Introduction: Up to 50% of patients with acute heart failure (AHF) have preserved left ventricular ejection fraction (HFPEF group)1. Due to diverse activated pathophysiological pathways, there should be a difference in biomarkers release in heart failure with preserved ejection fraction (HFPEF) and reduced ejection fraction (HFREF). BNP is the best studied biomarker in AHF, but we want to investigate difference in release of troponin (marker of myocytes stress and injury), tumor marker CA125 (marker of congestion and volume overload om HF) and cystatin C (marker of interstitial fibrosis).

The r enal damage is an emerging complication of excess weight.  Aim of this study was to determine the occurrence of chronic kidney disease (CKD) in subjects depending on their weight and the influence of body mass index (BMI) on glomerular filtration (GF) rate decline in outpatients with hypertension and/or diabetes mellitus type 2. Methods: This observational, cross sectional, pilot study included 200 adult patients suffering from hypertension and/or diabetes mellitus type 2 from March 2012. to March 2013. in the Institute for Occupational Medicine of Canton Sarajevo. Renal function was evaluated by using MDRD equation and measurement of microalbuminuria and proteinuria in 24 - hour urine, using nefelometric method at the Institute of Clinical Biochemistry of the University Clinical Center in Sarajevo K/DOQI classification  was used to define the stages of CKD. Results: Of the total 200 patients (62.5% male; mean age of 52.46 ± 8.2 years) most of them had a BMI of 25 - 30 (n=99; 49.5%). Most patients with a body mass index above 30 suffered from hypertension associated with diabetes mellitus type 2 (n=23; 34.3%,  p<0.05). The average values of BMI were statistically higher in men than in women (29.16±4.4 vs. 27.76±3.7). Early CKD was found in 118 patients (59.0%), mostly those with a BMI above 30 (63.8%). Conclusion: Early detection of CKD in primary care should definitely be a priority, especially in high - risk patients. It is also necessary to increase work on the prevention of obesity in order to prevent disease progression.

Background: Intraneural (intrafascicular) injection of various solutions can result in a mechanical injury to the fascicle(s). Additional injury can be expected when injectate has neurotoxic properties. In this study we examined the neurologic consequences of intraneurally injected lidocaine 2% and 0.9% NaCl. We postulated that intraneural injection of lidocaine 2% results in greater and longer-acting neurologic deficit in rats compared to intraneural injection of 0.9% NaCl. Methods and Materials: The study was conducted in accordance with the principles of laboratory animal care and was approved by the Laboratory Animal Care and Use Committee. Twenty four adult Wistar rats (300 g) both sexes were studied. After induction of general anesthesia (ether), the median nerve was exposed bilaterally. Under direct vision, a 27-gauge needle was placed either perineurally (n=24) or intraneurally (n=24), and 3 mL of preservative-free lidocaine 2% or 0.9% was injected using an automated infusion pump (3ml/min). Injection pressure data were acquired using an in-line manometer coupled to a computer via an analog-to-digital conversion board. After injection, the rats were awakened and subjected to serial neurologic examinations. Neurologic examination protocol was followed to determine grip strength and toe pinch reaction. Day 7 of the experiment, the animals were sacrificed and the neural tissue histologically examined. Results: Over the week following the procedure, all animals in both injection protocols (intraneural and perineural) initially lost and subsequently regained grip strength and paw pinch withdrawal reflex. Animals in the perineural group fully recovered grip strength and toe pinch score within 24-hours of surgery; the saline group showed more rapid recovery. In contrast, neither the lidocaine 2% or 0.9% saline intraneural group fully recovered a grip strength or toe pinch until the 7th or 4th day of recovery, respectively. There were no differences in the extent of neurologic impairment or speed of recovery between the saline and lidocaine 2% groups. Post-hoc comparisons of the four injection group by treatment condition effect at each testing interval post-surgery showed superior recovery in the perineural injected preparations at all intervals tested after hour 4 (p < 0.001). The average peak pressure for the intraneural injection group was 80.96 ± 20.94 kPa versus 21.63 ± 5.58 kPa for the perineural injection group (p < 0.0001). Histologic features of the injured tissues ranged from perineural ablation, cellular infiltration to destruction of neural architecture and axonal degeneration in intraneural preparations. No differences in this regard were found between lidocaine 2% and saline 0.9% groups. Conclusions: Intraneural injection of lidocaine 2% or 0.9% NaCl result in an indistinguishable neurologic deficit that is similar both in extent and duration. Intraneural injection is associated with significantly higher injection pressure as compared to the perineural injection. These results suggest that the main mechanism of neurologic injury resulting from an intraneural injection of lidocaine 2% may be a mechanical, injury to the fascicle(s), rather than a direct neurotoxicity.

Introduction: Many epidemiological studies have shown that there are numerous risk factors for acute coronary disease. The aim is to determine the effect of risk factors on the echocardiographic changes and quality of life in patients treated with different methods 1 year after myocardial infarction. Methods: The research was a prospective–retrospective, clinical, epidemiological study and was conducted at the Clinic of Cardiology, University Clinical Center Sarajevo. Patients were divided into four groups based on the therapy treatment they got. The patients were divided into four groups based on the therapy treatment they received. The first group consisted of 40 patients who had had myocardial infarction and were treated with medications. The patients in the groups II and III were treated with percutaneous coronary intervention (PCI) [who immediately after incident underwent primary PCI or delayed PCI], and each group consisted of 40 patients. The group IV consisted of 40 patients, who underwent surgical revascularization (coronary artery bypass surgery). After the treatments have finished, an echocardiogram was performed on every patient. The Short Form (SF)-36 health survey was used for testing the life quality. Echocardiogram and the quality of life (QoL) testing were repeated a year after the treatment. Results: The study included 160 patients with a history of myocardial infarction, of which 130 (81.3%) were men, and 30 (18.8%) were women. The average age in the total sample was 54.9 ± 8.8 years. The review of risk factors’ presence showed that in the total sample, most present was hypertension with 134 (83.8%), smoking with 120 (75.0%), and hypercholesterolemia with 110 or 68.8% of patients. Hypertension showed a statistically significant negative effect on the SF-scales only in the group III according to the mental health (P = 0.020), social functioning (P = 0.013), and pain (P = 0.011). A statistically significant effect of smoking was observed in the group III according to left ventricular internal dimension in end-diastole (P = 0.000) and left ventricular internal dimension in end-systole (P = 0.001) in the sense that smokers have the higher values of these parameters, and negative to ejection fraction (EF) (P = 0.001) in the sense that smokers have lower EF. In the group IV, positive correlation was observed to EF (P = 0.038), and negative toward the mitral regurgitation (P = 0.032). Conclusion: High blood pressure negatively affected the QoL. Smoking is negatively associated with all observed echocardiographic parameters in all the groups except with the size of the left atrium.

Introduction: Cardiovascular diseases are the leading cause of death in most countries. The aim was to examine the quality of life and to determine the differences in the quality of life in patients one year after myocardial infarction and the relationship between quality of life and echocardiographic parameters in these patients. Material and Methods: The research was a prospective, clinical, epidemiological study and was conducted at the Clinic of Cardiology, University Clinical Center Sarajevo (UCCS). The research was conducted on a sample of 160 patients who had acute myocardial infarction, which are based on the therapeutic procedures divided into four groups. The average age in the total sample was 54.9±8.8 years (range 37-76 years). The research was conducted one year after myocardial infarction (I group of subjects) or 12 months after PCI therapeutic procedures (II and III group of respondents) or coronary artery bypass surgery (IV group of respondents). Results: Comparison of the mean scores of scales in SF-36 questionnaire showed that the highest total score had patients in the group II 67.3±15.2, and the lowest in the group I 57.8±21.4. The increase in ejection fraction leads to a statistically significant increase in quality of life scores at all subscales, in all groups, so that EF has the greatest impact on the quality of life in all respondents. Statistically significant differences in the effects of mitral regurgitation in particular groups have been recorded only in the case of the mental health scale. Conclusions: Ejection fraction has the greatest impact on the quality of life in all patients, regardless of the type of medical treatment.

Introduction: The term masked hypertension (MH) should be used for untreated individuals who have normal office blood pressure but elevated ambulatory blood pressure. For treated patients, this condition should be termed masked uncontrolled hypertension (MUCH). Research Objectives: Masked uncontrolled hypertension (MUCH) has gone unrecognized because few studies have used 24-h ABPM to determine the prevalence of suboptimal BP control in seemingly well-treated patients, and there are few such studies in large cohorts of treated patients attending usual clinical practice. This is important because masked hypertension is associated with a high risk of cardiovascular events. This study was conducted to obtain more information about the association between hypertension and other CV risk factors, about office and ambulatory blood pressure (BP) control as well as on cardiovascular (CV) risk profile in treated hypertensive patients, also to define the prevalence and characteristics of masked uncontrolled hypertension (MUCH) among treated hypertensive patients in routine clinical practice. Patients and methods: In this study 2514 male and female patients were included during a period of 5 years follow up. All patients have ambulatory blood pressure monitoring (ABPM) for at least 24h. We identified patients with treated and controlled BP according to current international guidelines (clinic BP, 140/90mmHg). Cardiovascular risk assessment was based on personal history, clinic BP values, as well as target organ damage evaluation. Masked uncontrolled hypertension (MUCH) was diagnosed in these patients if despite controlled clinic BP, the mean 24-h ABPM average remained elevated (24-h systolic BP ≥130mmHg and/or 24-h diastolic BP ≥80mmHg). Results: Patients had a mean age of 60.2+10 years, and the majority of them (94.6%) were followed by specialist physicians. Average clinic BP was 150.4+16/89.9+12 mmHg. About 70% of patients displayed a very high-risk profile. Ambulatory blood pressure monitoring (ABPM) was performed in all recruited patients for at least 24h. Despite the combined medical treatment (78% of the patients), clinic control (<140/90 mmHg) was achieved in only 26.2% of patients, the corresponding control rate for ambulatory BP (<130/80 mmHg) being 32.7%. From 2514 patients with treated BP, we identified 803 with treated and controlled office BP control (<140/90 mmHg), of whom 258 patients (32.1%) had MUCH according to 24-h ABPM criteria (mean age 57.2 years, 54.7% men). The prevalence of MUCH was slightly higher in males, patients with borderline clinic and office BP (130–139/80–89 mmHg), and patients at high cardiovascular risk (smokers, diabetes, obesity). Masked uncontrolled hypertension (MUCH) was most often due to poor control of nocturnal BP, with the proportion of patients in whom MUCH was solely attributable to an elevated nocturnal BP almost double that solely attributable to daytime BP elevation (22.3 vs. 10.1%, P 0.001). Conclusion: The prevalence of masked suboptimal BP control in patients with treated and well-controlled clinic BP is high. The characteristics of patients with MUCH (male, longer duration of hypertension, obesity, smoking history, and diabetes) indicate that this is a higher-risk group with most to gain from improved BP.

Introduction: The commonest mitral regurgitation etiologies are degenerative (60%), rheumatic post-inflammatory, 12%) and functional (25%). Due to the large number of patients with acute MI, the incidence of ischaemic MR is also high. Ischaemic mitral regurgitation is a complex multifactorial disease that involves left ventricular geometry, the mitral annulus, and the valvular/subvalvular apparatus. Ischaemic mitral regurgitation is an important consequence of LV remodeling after myocardial infarction. Research Objectives: The objective of this study is to determine the role of echocardiography in detecting and assessment of mitral regurgitation mechanism, severity, impact on treatment strategy and long term outcome in patients with myocardial infarction during the follow up period of 5 years. Also one of objectives to determine if the absence or presence of ischaemic MR is associated with increased morbidity and mortality in patients with myocardial infarction. Patients and methods: The study covered 138 adult patients. All patients were subjected to echocardiography evaluation after acute myocardial infarction during the period of follow up for 5 years. The patients were examined on an ultrasound machine Philips iE 33 xMatrix, Philips HD 11 XE, and GE Vivid 7 equipped with all cardiologic probes for adults and multi-plan TEE probes. We evaluated mechanisms and severity of mitral regurgitation which includes the regurgitant volume (RV), effective regurgitant orifice area (EROA), the regurgitant fraction (RF), Jet/LA area, also we measured the of vena contracta width (VC width cm) for assessment of IMR severity, papillary muscles anatomy and displacement, LV systolic function ± dilation, LV regional wall motion abnormality WMA, LV WMI, Left ventricle LV remodeling, impact on treatment strategy and long term mortality. Results: We analyzed and follow up 138 patients with previous (>16 days) Q-wave myocardial infarction by ECG who underwent TTE and TEE echocardiography for detection and assessment of ischaemic mitral regurgitation (IMR) with baseline age (62 ± 9), ejection fraction (EF 41±12%), the regurgitant volume (RV) were 42±21 mL/beat, and effective regurgitant orifice area (EROA) 20±16 mm2, the regurgitant fraction (RF) were 48±10%, Jet/LA area 47±12%. Also we measured the of vena contracta width (VC width cm) 0,4±0,6 for assessment of IMR severity. During 5 years follow up, total mortality for patients with moderate/severe IMR–grade II-IV (54.2±1.8%) were higher than for those with mild IMR–grade I (30.4±2.9%) (P<0.05), the total mortality for patients with EROA ≥20 mm2(54±1.9%) were higher than for those with EROA <20 mm2(27.2±2.7%) (P<0.05), and the total mortality for patients with RVol ≥30 mL (56.8±1.7%) were higher than for those with RVol<30ml (29.4±2.9%) (P<0.05). After assessment of IMR and during follow up period 64 patients (46%) underwent CABG alone or combined CABG with mitral valve repair or replacement. In this study, the procedure of concomitant down-sized ring annuloplasty at the time if CABG surgery has a failure rate around 24% in terms of high late recurrence rate of IMR during the follow period especially after 18–42 months. Conclusion: The presence of ischaemic MR is associated with increased morbidity and mortality. Chronic IMR, an independent predictor of mortality with a reported survival of 40–60% at 5 years. Ischaemic mitral regurgitation has important prognosis implications in patients with coronary heart disease. Recognizing the mechanism of valve incompetence is an essential point for the surgical planning and for a good result of the mitral repair. It is important that echocardiographers understand the complex nature of the condition. Despite remarkable progress in reparative surgery, further investigation is still necessary to find the best approach to treat ischaemic mitral regurgitation.

Abstract Introduction. Cardiovascular diseases are the leading cause of death in hemodialysis patients. The decline of residual renal function increases the prevalence and severity of risk factors of cardiovascular morbidity and mortality in these patients. Hypertension is common in dialysis patients and represents an important independent factor of survival in these patients. Methods. The study included 77 patients who are on chronic HD for longer than 3 months. Depending on the measured residual diuresis patients were divided into two groups. The study group consisted of patients with residual diuresis >250 ml/day, while patients from control group had residual diuresis <250 ml/day. All patients had their blood pressure measured before 10 consecutive hemodialysis treatments. Collected data were statistically analyzed using SPSS 16.0. Results. The study included 77 hemodialysis patients, mean age of 56.56±14.6 years and mean duration of hemodialysis treatment of 24.0 months. Of the total number of patients, 39(50.6%) had preserved residual renal function. Hypertension was more common in the group of patients who did not have preserved residual renal function (68.4% vs 25.6%). There was statistically significant negative linear correlation between the volume of residual urine output and the residual clearance of urea and values of systolic blood pressure [(rho=−0.388; p<0.0001); (rho=−0.392; p<0.0005)], values of mean arterial pressure [(rho =−0.272; p<0.05); (rho=−0.261; p=0.023; p<0.05)] and values of pulse pressure in hemodialysis patients [(rho =−0.387; p<0.001); (rho=−0.400; p<0.0005)]. Conclusions. Residual renal function plays an important role in controlling blood pressure in patients on hemodialysis. More attention should be directed to preserve residual renal function, and after the start of hemodialysis by avoiding intensive ultrafiltration with optimal antihypertensive therapy.

AIM To analyze differences in quality of life between smokers and non-smokers in relation to socioeconomic factors. METHODS This study was conducted on a sample of 600 respondents equally divided in two groups, smokers (300) and non-smokers (300). Former smokers were excluded. The study included both sexes equally further distributed into age groups: 19-34, 35- 49, 50-64 and 65-70 years. A questionnaire SF-36 to test the quality of life (36 questions measuring eight dimensions of quality of life) and questionnaire EuroQoL to examine the socioeconomic status was used. For the assessment of a given factor impact multivariant and univariant analyses of variance were used. RESULTS A significant difference in the quality of life between smokers and non-smokers according to the gender was found, but only at the subscales of physical functioning and bodily pain (p=0.000). An analysis of individual dimensions of quality of life in relation to marital status of smokers and non-smokers showed significant differences on the subscales of physical functioning (p=0.032), vitality (p=0.0430) and mental health (p=0.016). An analysis of life quality in relation to smoking status of respondents and the average monthly income showed that the average scores on all subscales were higher in non-smokers compared to smokers (p=0.000) and they were increased with the average monthly income. CONCLUSION The results of this study prove that there are significant differences in quality of life according to the smoking status. Also the socioeconomic factors which include age, gender, the surrounding, marital status, employment, total monthly income and level of education are of great influence on the quality of life with significant differences in relation to smoking status.

OBJECTIVE To assess serum levels of tumor marker carbohydrate antigen 125 (CA125) in patients with heart failure (HF) and to investigate possible correlation with echocardiographic parameters and level of brain natriuretic peptide (BNP). PATIENTS AND METHODS We included 76 patients with different cardiac symptoms hospitalized at Clinic for heart disease and rheumatism. Control group (n = 26) was consisted of patients without signs and symptoms of HF, normal left ventricle ejection fraction (LVEF) and normal BNP level. Patients with diagnosis of HF (n = 50) were subdivided into 2 group depending on signs and symptoms of fluid overload: compensated (compHF, n = 10) and decompensated group (decompHF, n = 40). Serum CA125 and BNP were measured on admission and all patient underwent ECG recording and trans thoracic echocardiographic examination. RESULTS The median CA125 level in HF group was significantly higher compared to control group (71.05 [30.70-141.47]U/ml vs 10.75 [8.05- 14.32] U/ml, p < 0.0005). Higher CA125 levels were found in decompHF group compared to compHF group (94.90 [49.75-196.75]U/ml vs 11.90 [10.25-15.80]U/ml, p < 0.0005). In decompHF group 13 of patients had pleural and/or pericardial effusion- their CA125 levels were significantly higher compared to patients without serosal effusion (n = 27) (205.10 [106.50-383.90]U/ml vs. 71.50 [47.30-109.55] U/ml, p < 0.002). We found significant difference in CA125 levels between patients with atrial fibrillation and sinus rhythm (98.40 [48.20-242.70] U/ml vs. 47.30 [12.95-99.05] U/ml, p = 0.015). There was no significant difference in CA125 levels in group with enlarged left atrium compared to normal sized atrium (p = 0.282), as well as in group with moderate/severe mitral regurgitation compared to group with no/mild mitral regurgitation (p = 0.99). Finally, levels of serum CA125 positively correlated with serum level of BNP (r = 0.293, p = 0.039), but not with LVEF (p = 0.369) and left atrium diameter (p = 0.636). CONCLUSION Serum CA125 is elevated in decompensated HF patients: more pronounced elevation was found in patients with pleural and/or pericard effusion compared to patients with no serosal effusion. CA125 level correlated with BNP, but not with left atrium diameter nor with LVEF. Tumor marker CA125 could be used as a marker of systemic congestion and volume overload in decompensated HF. We hypothesized that high CA125 level indicates that measured high BNP is actually wet BNP.

INTRODUCTION Usage of fibrinolytic therapy leads to reperfusion of the occluded coronary arteries, rescue of ventricle myocardium and successful recovery of patient. GOAL The objective of this study was to compare the reperfusion effect of streptokinase and alteplase in acute myocardial infarction (AMI) by analyzing echocardiographic parameters and post-coronarography treatment. PATIENTS AND METHODS We observed 53 patients in AMI and divided them depending on applied therapy in streptokinase and alteplase group. Both groups were further divided into three subgroups depending on the time passed from chest pain occurrence to admission at Clinic. Observed echocardiographic parameters were: mitral regurgitation, left ventricular systolic and diastolic function and signs of ischemic cardiomyopathy. On coronary angiogram we analyzed severity of coronary artery disease as well as recommended treatment thereafter. RESULTS There were no significant difference in post-coronarography treatment, incidence and severity of mitral regurgitation and ischemic cardiomyopathy in alteplase vs streptokinase group- only significantly less diastolic dysfunction was noted in alteplase group (p=0.037). We noticed only significant difference when we took into consideration time from chest pain to admission at clinic. In alteplase first subgroup were more patients treated only with medications (without need for revascularization) vs streptokinase first subgroup (62,5% vs 28.6%, p=0.047). In alteplase first subgroup was lower incidence of mitral regurgitation (p =0.045), developed cardiomyopathy (p =0.009) and more preserved left ventricular diastolic function (p =0.008) compared to first streptokinase subgroup. CONCLUSION In our study we have found a significant difference between streptokinase and alteplase in echocardiographic parameters and post-coronarography treatment when we took into consideration time from occurrence of chest pain to admission at Clinic. The best outcomes had patients who were treated with alteplase within 1.5 hour from occurrence of chest pain.

Brain natriuretic peptide (BNP) is released from ventricular myocites due to their stretching and volume overload. In heart failure there is BNP release. Aim of this study was to observe BNP release in acute myocardial infarction (AMI). We measured BNP in 75 patients with AMI. Control group (n=61) was similar by age and gender to AMI group. We found statistically significant elevation of BNP compared to controls (462.875 pg/ml vs 35.356 pg/ml, p< 0.001). Patients with severe systolic dysfunction had the highest BNP levels, while patients with the preserved systolic function had the lowest BNP levels (Group with EF< 30% BNP= 1129.036 pg/ml vs Group with EF31-40 % BNP= 690.177 pg/ml vs Group with EF 41-50% BNP= 274.396 pg/ml vs Group with EF> 51% BNP= 189.566 pg/ml, p< 0.001). We found statistically significant light positive correlation between BNP and left ventricle end-diastolic diameter (LVDd) (r= 0.246, p<0.05). and real positive correlation between BNP and peak troponin levels (r= 0.441, p < 0.05). BNP levels were higher in anteroseptal allocation of AMI compared to inferior allocation (835.80 pg/ml vs 243.03 pg/ml, p< 0.001) and in patients who were treated with heparin compared to fibrinolitic therapy (507.885 pg/ml vs 354.73 pg/ml, p< 0.05). BNP is elevated in AMI and is a quantitative biochemical marker related to the extent of infarction and the left ventricle systolic dysfunction. Besides echocardiographic calculation, elevation of BNP could be used for quick and easy determination of the left ventricle systolic dysfunction.

AIM γ-glutamyl transferase (GGT) is an independent prognostic marker for cardiac death and reinfarction in patients with coronary artery disease, but its clinical significance during early postmyocardial infarction period is unclear. PATIENTS & METHODS This short-term prospective study included 40 patients with acute myocardial infarction (AMI) in whom we determined GGT activity, lipids, uric acid, homocysteine (Hcy), high sensitivity C-reactive protein (hsCRP) and left ventricular (LV) function on admission and on day 5 following AMI. RESULTS In AMI patients on admission, logGGT was associated with logHcy (r = 0.36), uric acid (r = 0.48) and CK-MB activity (r = -0.41). Uric acid remained an independent determinant of serum GGT activity on admission. Significant increase in GGT activity (77.7%) was observed following AMI. On day 5 serum logGGT was significantly associated with LV relative wall thickness (r = -0.37), LV end-diastolic diameter (r = 0.41) and LV fractional shortening (r = -0.36). In addition, a significant positive correlation was found between serum logGGT and loghsCRP (r = 0.41) and logHcy values (r = 0.395), but only LV end-diastolic diameter remained independently associated with serum GGT activity on day 5 following AMI. CONCLUSION GGT is associated with oxidative/inflammatory markers and LV diastolic diameter suggesting its potential role in predicting LV dilatation and dysfunction during the early postmyocardial infarction period.

This study evaluated brain natriuretic peptide (BNP) release in acute myocardial infarction (AMI), absolute values as well as pattern of its release. There are two different patterns of BNP release in AMI; monophasic pattern--concentration in the first measurement is higher than in the second one, and biphasic pattern--concentration in the first measurement is lower than in the second one. We observed significance of biphasic and monophasic pattern of BNP release related to diagnostic and prognostic value. We included in this prospective observational study total of 75 AMI patients, 52 males and 23 females, average age of 62.3 +/- 10.9 years with range of 42 to 79 years. BNP was measured and pattern of its release was evaluated. In AMI group BNP levels were significantly higher than in controls (462.88 pg/mL vs. 35.36 pg/mL, p < 0.001). We found statistically significant real negative correlation (p < 0.05) between BNP concentration and left ventricle ejection fraction (LVEF) with high correlation coefficient (r = -0.684). BNP concentrations were significantly higher among patients in Killip class II and III compared to Killip class I; Killip class I BNP = 226.18 pg/mL vs. Killip class II 622.51 pg/mL vs. Killip class III 1530.28 pg/mL, p < 0.001. BNP concentrations were significantly higher in patients with; (i) myocardial infarction vs. controls; (BNP 835.80 pg/mL vs. 243.03 pg/mL); (ii) in pts with positive major adverse cardiac events (MACE) vs. negative MACE (BNP 779.08 pg/mL vs. 242.28 pg/mL, p < 0.001); (iii) in pts with positive compared to negative left ventricle (LV) remodelling (BNP 840.77 pg/mL vs. 341.41 pg/mL, p < 0.001). Group with biphasic pattern of BNP release had significantly higher BNP concentration compared to monophasic pattern group. In biphasic pattern group we found significant presence of lower LVEF, Killip class II and III, LV remodelling and MACE. We found that BNP is strong marker of adverse cardiac events in patients presenting with a myocardial infarction. In our AMI group we found significant elevation of BNP and it is suspected that second peak secretion is not only due to systolic dysfunction and subsequent remodeling of LV but also due to impact of ischaemia. Patients with biphasic pattern probably have worse prognosis due to severe coronary heart disease. Besides its diagnostic role as a simple blood marker of systolic function, BNP is also important prognostic marker who helps making clinical decision about early invasive vs. conservative management.
