Introduction: Myocardial infarction is fatal one-third of patients. In others, concequences can be different forms and degrees of complications, e.g. left ventricular dysfunction. Fibrinolythic therapy is the only non-invasive treatment that directly influences the infarction outcome. The purpose of the study was to compare systolic function of the left ventricle measured by ejection fraction in circumstances in which an acute myocardial infarction was treated by primary stent implantation, by administration of fibrinolytic agent streptokinase, and medical treatment when none of the above mentioned methods has been used. Material and methods: A retrospective-prospective study was conducted with a sample of 90 patients, that were hospitalized in 2005 and 2006 for acute myocardial infarction, mean age being of 56±7. Patients were divided into three groups, with 30 patients in each: a group of patients refered to primary stenting, a group that received streptokinase, and a group of patients that were not treated with either of these methods. Elecrocardiogram and echocardiographic study were performed on all patients. Results: Ejection fraction was 58%±8 in stented group, 47%±7 in streptokinase group, and 33%±8 in group without either (p< .001). Discussion and Conclusion: Global systolic left ventricular function was significantly better in the group of stented patients compared to the one in patients treated with streptokinase. Streptokinase administered in the first 6 hours from myocardial infarction onset significantly improves preservation of left ventricular systolic function compared to conditions in which no fibrinolysis is used.

In this study we investigated the association of the interleukin-1 receptor antagonist gene variable number tandem repeat (IL1RN VNTR) polymorphism and of the inhibitor of kappa B-like protein (IKBL) gene polymorphism with myocardial infarction (MI) in a group of patients with type 2 diabetes. The IL1RN VNTR and the IKBL+ 738T > C gene polymorphisms were tested in 374 Caucasians: 151 cases with MI and 223 subjects with no history of coronary artery disease. The IL1RN VNTR polymorphism was not a risk factor for MI in Caucasians with type 2 diabetes (genotype 22 vs. the rest: odds ratio (OR) 1.6; 95% confidence interval (CI) = 0.8-3.5; p = 0.2). We also failed to demonstrate that IKBL+ 738T > C gene polymorphism was associated with MI in patients with type 2 diabetes (OR = 0.9; 95% CI = 0.3-2.6; p = 0.9). We provide evidence that the IL1RN VNTR and the IKBL + 738T > C gene polymorphisms are not risk factors for MI in Caucasians with type 2 diabetes.

Intracardial electrophysiology testing is in use to estimate mechanism of heart rate dysfunction, and is the most useful procedure in treatment of arrhythmias and dysfunction in impulse conduction. QRS complex is main electrocardiographically characteristic for supraventricular and ventricular tachycardia, because of that tachycardia can be with narrow QRS complex or with wide QRS complex. Tachycardia with narrow QRS complex is one where the QRS complex last <120 millisecond. Atrioventricular node reentry tachycardia in reentry flow involves atrioventriculare node and surrounding atrial tissue. Wide QRS tachycardia (120 millisecond) can be supraventricular arrhythmias with continuous or frequent dependent aberrant intraventricular conduction and supraventricular arrhythmias with anterograde preexcitacion and ventricular arrhythmia.Safety and cost effectiveness of radiofrekvent ablation, made ablation method of choise in most patients with supraventricular rhythm disorders.

Genetic epidemiology studies of hereditary hemochromatosis (HHC) have shown a high prevalence of the C282Y mutation in individuals of the North Western European origin, whereas lower prevalence of HFE gene mutations was detected in the populations from southern European countries. However, no HFE mutation prevalence data have been provided for the population of Bosnia-Herzegovina so far. Therefore, the aim of this study was to determine the frequency of the C282Y and H63D HFE gene mutations in the population of Bosnia-Herzegovina. Among 200 analysed subjects 8 (4%) were C282Y heterozygotes; no C282Y homozygotes were found. The frequency of the H63D allele was 11.5%. There were 33 (16.5%) heterozygotes and 6 (3%) homozygotes for the H63D mutation. One (0.5%) compound heterozygote C282Y/H63D was identified. The observed C282Y and H63D allele frequency was 2.25% (95% confidence interval: 1.2-4.2) and 11.5% (95% confidence interval: 8.7-14.9), respectively. The prevalence of the C282Y and H63D mutations was estimated in Bosnia-Herzegovina, which fit well in the European northwest-to-southeast gradient of the C282Y mutation distribution. In addition, these results have an important implication for clinical evaluation of HHC in Bosnia-Herzegovina.

Atrial fibrillation characterized by uncoordinated atrial activation. On the electrocardiogram is described by the replacement of consistent P waves by rapid oscillations or fibrillatory waves that vary in size and shape. The incidence of atrial fibrillation in patients under 22 years old is 2%, whereas for patients under 60 years old, the incidence is 8.8%. The most common cause of death in patient with atrial fibrillation is stroke, and occurs in 1% to 5% patients in the age group 50 to 59 years, whereas 30% patients in the age group 80 to 89 years. The incidence of atrial fibrillation after coronary artery bypass surgery occurs in 20% to 40% patients. We examined the incidence atrial fibrillation in patients after coronary artery bypass surgery, most common risk factors for occurs atrial fibrillation. Prospective study was conducted on 100 patients, who were divided in two groups, which had similar age structure, gender and they had disease coronary artery which required coronary artery bypass surgery. We established that incidence atrial fibrillation after coronary artery bypass surgery was 24%. Age was one of main risk factors that is responsible for appearance of atrial fibrillation. Gender like risk factor at 60 year old persons does not have statistical significance, while at persons which are younger then 60 years male has greater statistical significance like risk factor. Patients with triple vessel disease after coronary artery bypass surgery had most common atrial fibrillation.

Angiotensin II is the major effector molecule of renin-angiotensin system; its production can be conveniently interrupted by angiotensin-converting enzyme (ACE). Typical plasma levels of ACE accompany the I/D polymorphism; however, a controversy exists as to whether the DD genotype of the ACE polymorphism affects the risk for the development of coronary artery disease (CAD) and to what extent the ACE polymorphism is associated with CAD in different populations. We compared the I/D polymorphism in 212 CAD patients younger than 50 years with 165 healthy control individuals. They were all from the Tuzla region in Bosnia and Herzegovina. Patients with CAD had a higher prevalence of the DD genotype (36.3%) than controls (25.6%). The odds ratio for the ACE DD genotype in CAD patients was 1.7 (95% confidence interval 1.0-2.7; p < 0.05). We may conclude that the D/D genotype of the ACE gene polymorphism is associated with an increased risk for CAD in the Bosnian population.

Intervenient cardiology is significantly more represented in attempts to solve problems of heart coronary artery disease in comparison to aortocoronary bypass procedures. Resthenoses of coronary artery blood vessel after PTCA, or PTCA and stent placement are frequent. The main causes are: neointimal hyperplasia, late contraction, and remodelling. The application of brachitherapy offers the possibility to prevent resthenosis especially stent resthenosis. Our report encompasses eight patients diseased from coronary artery occlusionn. Half of there patients had a stent resthenosis. The average degree of blood vessel occlusionn before the intervenient manipulation was 78%, and after treatment 25%-30%. Early results after recanalisation of coronary blood vessel are thus fat satisfactory, but results are to be followed carefully.
