Acute pulmonary embolism (PE) management guidelines categorize normotensive patients with right ventricle dysfunction (RVD) and normal cardiac troponin (cTn) as intermediate low risk. This study explores the prevalence of cardiovascular comorbidities and their impact on risk stratification in this specific cohort. To investigate the characteristics of normotensive acute PE patients with RVD and normal cTn, emphasizing the role of pre-existing cardiovascular diseases in determining the intermediate-low risk status. A total of 1675 PE patients from a regional registry were screened, excluding high-risk and intermediate-high-risk cases. Among the remaining 400 normotensive patients with RVD, 353 with echocardiography and normal cTn were included. Patients were categorized into low or intermediate-low risk based on RVD presence. Cardiovascular comorbidities were assessed, and logistic regression analyzed their association with intermediate-low risk. Intermediate-low-risk patients (n=137) exhibited significantly higher rates of chronic heart failure, arterial hypertension, coronary artery disease, diabetes, and atrial fibrillation compared to low-risk patients (n=216). A substantial 77.4% of intermediate-low-risk patients had at least one cardiovascular comorbidity, significantly elevating the risk of RV dysfunction (adjusted OR 2.954, p<0.001). The all-cause hospital mortality was 5.1% in intermediate-low-risk and 1.4% in low-risk PE. Normotensive acute PE patients with RVD and normal cTn are predominantly burdened with chronic cardiovascular conditions. The majority of intermediate-low-risk patients have at least one cardiovascular comorbidity, indicating an increased risk of death during hospitalization compared to low-risk patients. This study underscores the necessity for nuanced risk stratification considering pre-existing cardiovascular diseases for tailored and effective management. These findings have important implications for optimizing treatment strategies and improving outcomes in this high-risk population.
Active malignant disease is associated with pulmonary embolism and the treatment of this condition is very challenging. The efficacy and safety of thrombolytic therapy for acute severe PE in patients with active malignant disease is unknown. This study aimed to investigate hospital mortality rate and the incidence of major bleeding at 7 days according to the International Society of Thrombosis and Hemostasis (ISTH) criteria in patients with active malignant disease who were treated with thrombolytic therapy due to severe acute PE. Patients with acute PE proven by computed tomography pulmonary angiography who were admitted to intensive care units have enrolled in the Regional PE Registry (REPER) since 2015, consisting of 10 hospitals from the 4 east Balkan countries. The decision to use thrombolytic therapy was at the discretion of the attending physicians, and it was used in high-risk, and intermediate-high-risk PE patients. Hospital mortality and the incidence of major bleeding at 7 days were compared between patients with active cancer and those without it who received thrombolytic therapy. Alteplase-based therapy was used. Among 2070 patients with acute PE enrolled in REPER, intermediate-high and high-risk PE had 795 patients without malignant disease and 135 had active malignant disease in the last 6 months. Patients with malignant disease had less chance to be treated with thrombolysis than patients without it (29.1% vs 44.7%, OR 0.508, 95%CI 0.341-0.756, p=0.001). For patients treated with thrombolysis, hospital mortality was non significantly higher in patients with the malignant disease compared to patients without it (25.6% vs 16,1%, OR 1.803, 95%CI 0.833-3.904, p=0.132), and the incidence of major bleeding at seven days was similar (15.4% vs 18.5%, OR 0.800, 95%CI 0.322-1.989, p=0.6131). There was no significant difference in age, sex, and PE risk distribution between patients with active malignant disease and those without it who were treated with thrombolysis. Thrombolytic therapy seems to be underutilized in patients with the active malignant disease compared to patients without it in severe acute PE. In the selected patients who were treated with thrombolysis for severe acute PE, the efficacy and safety are similar between patients with and without active malignant disease.
Alcohol drinks, especially wine, have been described since 6,000 B.C. For many years in modern medicine, wine in moderation has been considered healthy for cardiovascular prevention, i.e., recommended by nutrition committees. Some regional guidelines still recommend one to two standard drinks per day. By the very recent (January 2023), World Health Organization and Canadian Guidance on alcohol emphasize that any alcoholic drink is hazardous to the health and the safe amount is zero. The risk starts with every single drop. It was also nicely summarized in the manuscript “Alcohol-dose question and the weakest link in a chemical interplay” (Explor Cardiol. 2023;1:15–25. doi: 10.37349/ec.2023.00003) especially from the standpoint of a researcher in the cardiovascular arena. The newest recommendations are based on observational studies and their meta-analysis, therefore establishing associations, pointing out that alcohol may somewhat prevent cardiovascular diseases and diabetes type 2, but with a significant increase in non-cardiovascular morbidity and mortality, especially cancers. Previous recommendations, therefore, may be obsolete as they were based on studies where abstainers from alcoholic beverages had inherent higher risks. The current controversy with conflicting guidelines for alcoholic beverage consumption in the era of precision medicine may stimulate more fundamental investigations up to genetic ones and find the cause-effect relations. In the era of precision medicine, it may come closer to discovering the causes of cancers and many other diseases, enabling predictions of reactions to alcoholic beverages by each person, not just in the population.
Background: Patients with acute pulmonary embolism (PE) may have various types of atrial fibrillation (AF). The role of AF in hemodynamic states and outcomes may differ between men and women. Methods: In total, 1600 patients (743 males and 857 females) with acute PE were enrolled in this study. The severity of PE was assessed using the European Society of Cardiology (ESC) mortality risk model. Patients were allocated into three groups according to their electrocardiography recordings taken during hospitalization: sinus rhythm, new-onset paroxysmal AF, and persistent/permanent AF. The association between the types of AF and all-cause hospital mortality was tested using regression models and net reclassification index (NRI) and integrated discrimination index (IDI) statistics with respect to sex. Results: There were no differences between the frequencies of the types of AF between men and women: 8.1% vs. 9.1% and 7.5% vs. 7.5% (p = 0.766) for paroxysmal and persistent/permanent AF, respectively. We found that the rates of paroxysmal AF significantly increased across the mortality risk strata in both sexes. Among the types of AF, the presence of paroxysmal AF had a predictive value for all-cause hospital mortality independent of mortality risk and age in women only (adjusted HR, 2.072; 95% CI, 1.274–3.371; p = 0.003). Adding paroxysmal AF to the ESC risk model did not improve the reclassification of patient risk for the prediction of all-cause mortality, but instead enhanced the discriminative power of the existing model in women only (NRI, not significant; IDI, 0.022 (95% CI, 0.004–0.063); p = 0.013). Conclusion: The occurrence of paroxysmal AF in female patients with acute PE has predictive value for all-cause hospital mortality independent of age and mortality risk.
INTRODUCTION Sodium-glucose cotransporter-2 (SGLT2) inhibitors are integral in treating patients with heart failure, regardless of the existence of diabetes mellitus. In light of their benefits on the heart muscle, the question of their effect on acute coronary syndrome is raised, and a hypothesis as to whether they can be implemented in its treatment is proposed. The aim of the article was to indicate the potential of using SGLT2 inhibitors in the treatment of myocardial infarction (MI). EVIDENCE ACQUISITION A PubMed search for articles published between October 2017 and May 2022 was conducted using the following keywords: "SGLT2 inhibitors," "Acute Coronary Syndrome," "Treatment," "Prognosis." Reference lists of identified articles were searched for further articles. EVIDENCE SYNTHESIS Reports from clinical trials and animal studies thus far investigating mechanistic pathways of SGLT2 inhibitors' effect in relation to acute myocardial infarction were interplayed to extract relevant findings and analyze the safety of this therapy in acute coronary syndrome (ACS) patients. CONCLUSIONS SGLT2 inhibitors indicate beneficial effects in acute cardiovascular incident by various mechanisms, and early initiation of therapy may improve outcomes for AMI survivors.
Background The incidence of the signs and symptoms of acute pulmonary embolism (PE) according to mortality risk, age and sex has been partly explored. Patients and methods A total of 1242 patients diagnosed with acute PE and included in the Regional Pulmonary Embolism Registry were enrolled in the study. Patients were classified as low risk, intermediate risk or high risk according to the European Society of Cardiology mortality risk model. The incidence of the signs and symptoms of acute PE at presentation with respect to sex, age, and PE severity was investigated. Results The incidence of haemoptysis was higher in younger men with intermediate-risk (11.7% vs 7.5% vs 5.9% vs 2.3%; p=0.01) and high-risk PE (13.8% vs 2.5% vs 0.0% vs 3.1%; p=0.031) than in older men and women. The frequency of symptomatic deep vein thrombosis was not significantly different between subgroups. Older women with low-risk PE presented with chest pain less commonly (35.8% vs 55.8% vs 48.8% vs 51.9%, respectively; p=0.023) than men and younger women. However, younger women had a higher incidence of chest pain in the lower-risk PE group than in the intermediate-risk and high-risk PE subgroups (51.9%, 31.4% and 27.8%, respectively; p=0.001). The incidence of dyspnoea (except in older men), syncope and tachycardia increased with the risk of PE in all subgroups (p<0.01). In the low-risk PE group, syncope was present more often in older men and women than in younger patients (15.5% vs 11.3% vs 4.5% vs 4.5%; p=0.009). The incidence of pneumonia was higher in younger men with low-risk PE (31.8% vs<16% in the other subgroups, p<0.001). Conclusion Haemoptysis and pneumonia are prominent features of acute PE in younger men, whereas older patients more frequently have syncope with low-risk PE. Dyspnoea, syncope and tachycardia are symptoms of high-risk PE irrespective of sex and age.
In modern cardiology, sodium‐glucose cotransporter 2 (SGLT2) inhibitors are critical components of heart failure (HF) treatment algorithms and exert their effects primarily by preventing glucose reabsorption and facilitating its urinary excretion. The objective was to systematically review randomized controlled trials (RCTs) assessing the effects of SGLT2 inhibitors, particularly canagliflozin, empagliflozin, dapagliflozin, ertugliflozin, sotagliflozin (dual SGLT inhibitor), and their use in HF. Systematic searches of PubMed/Medline, The Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov databases were performed. There were no restrictions imposed on the date and status of publication; however, there were restrictions on language for the searched studies. A total of 1139 records were identified in the bibliographic searches from both databases and the register of choice for this systematic review. Following duplicate removal, screening for titles and abstracts, and thorough assessment of full‐text articles, 12 RCTs met the inclusion criteria. Altogether, 83 878 patients were included in this review. Among the included studies, two RCTs, with six respective reports, investigated canagliflozin, four RCTs with 13 derived reports investigated dapagliflozin, three RCTs with 12 separate reports studied the effects of empagliflozin, one RCT and its three respective reports assessed ertugliflozin's effects, and two RCTs with one added report investigated the dual inhibitor sotagliflozin. Pooled meta‐analytic effects of SGLT2 inhibitors were as follows: on atrial fibrillation odds ratio (OR) = 0.83, 95% confidence interval (CI): 0.68–1.01, prediction interval (PI): 0.57–1.19; on HF hospitalization OR = 0.69, 95% CI: 0.60–0.78, PI: 0.60–0.78; on cardiovascular death OR = 0.82, 95% CI: 0.58–1.15, PI: 0.42–1.60; and on major adverse cardiovascular events OR = 0.90, 95% CI: 0.77–1.06, PI: 0.71–1.15. SGLT2 inhibitors significantly improve the quality of life in HF patients. Their beneficial effects on HF, especially in left ventricular dysfunction, have made their use possible irrespective of diabetes mellitus or atrial fibrillation status.
BACKGROUND Heat-not-burn (HNB) technology by the U.S. Food and Drug Administration has been classified as a modified risk tobacco product, which can be a better option for those populations who cannot give up the habit of smoking. The outlook on the effects of these products is quite controversial in the scientific world. OBJECTIVE To present the effect of HNB tobacco products on the cardiovascular system, with reference to the existence of possible benefits of the technology. METHODS The literature search was conducted in PubMed/Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov databases, with reliance on a well-defined guiding research statement. Quality appraisal was performed using the CASP checklist for randomized controlled trials. RESULTS The search of three databases identified 167 records, and after selection process, 25 randomized controlled trials were eligible for our study's criteria. Twenty studies investigated the effects of HNB products on biomarkers of clinical relevance. Five studies evaluated other functional heart parameters rather than biomarkers. CONCLUSION With HNB tobacco products, significant reductions were found in biomarkers of exposure and biological effect related to pathways involved in cardiovascular disease, including inflammation, oxidative stress, lipid metabolism, platelet function, and endothelial dysfunction.
