Occurrences of arrhythmias during the acute myocardial infarction is explained with local ischaemia, but mechanism of later occurrences is unclear. Our study had for the aim to examine relationship between postinfarction left ventricle dilatation and appearance of arrhythhmias, and to show drug effects on remodelling. Patients who developed progressive left ventricle dilatation had higher mortality then patients without changes of left ventricle volume, and mortality is due of sudden cardiac death. Drugs who had preventive effects or reverse remodelling can help in prevention of malignant arrhythhmias and sudden cardiac death. It is showed that ACE inhibitors, beta-blockers and aldosterone antagonists had preventive effects on left ventricle remodelling. The combined therapy with ACE inhibitors, beta-blockers and aldosterone antagonists is showed as the most-effective in prevention of remodelling, appearaance of arrhythhmias and sudden cardiac death.

The Association of Neutrophil to Lymphocyte Ratio and Other Complete Blood Count Parameters with Global Registry of Acute Coronary Events Risk Score in Patients with Non-ST Segment Elevation - Acute Coronary Syndrome: A Single-Center Study.

Background: The involvement of inflammation in the start and advancement of atherosclerotic plaques in acute coronary syndrome has been clarified. White blood cell count and its differential are key inflammatory markers in cardiovascular disease, with the neutrophil-to-lymphocyte ratio (NLR) emerging as a marker of inflammation and a predictor of mortality in patients with acute coronary syndrome. The study aims to investigate the utility of neutrophil to lymphocyte ratio and other complete blood count parameters as a risk stratification tool and independent predictor of Global Registry for Acute Coronary Events (GRACE) risk score in Non-ST segment elevation acute coronary syndrome (NSTE-ACS).

Introduction And Objectives: Iron deficiency (ID) is a well-known prognostic marker in heart failure (HF), independent of anemia. However, its impact in acute coronary syndromes (ACSs) is not well established.
Methods: This is a retrospective analysis of patients admitted with ACS from January to December 2019.
Association between the proportionality of functional mitral regurgitation and survival after mitral valve operation.

Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden. The clinical relevance of proportionality remains unknown in mitral operations for ischemic mitral regurgitation. We aimed to characterize the association between mitral regurgitation proportionality and outcomes after mitral valve operations.

Introduction: Pulmonary atresia with intact ventricular septum is a rare congenital cardiac lesion with significant anatomical heterogeneity. Surgical planning of borderline cases remains challenging and is primarily based on echocardiography. The aim was to identify echocardiographic parameters that correlate with surgical outcome and to develop a discriminatory calculator.

Electrical cardioversion presents one of the treatment options for atrial fibrillation (AF). However, the early recurrence rate is high, reaching ~40% three months after the procedure. Features based on vectorcardiographic signals were explored to find association with early recurrence of AF.
