Abstract

Ischemic heart disease (IHD) and acute coronary syndrome are the main cause of sudden cardiac death (SCD). Incidence of SCD in patients after myocardial infarction (MI) is 4-6-fold higher than in general population. The review focuses on electrophysiological changes during acute myocardial ischemia and mechanisms of myocardial electromechanical remodeling in remote period after MI. Current data on arrhythmia substrates and triggers are presented. Nowadays, the main guide for implantable cardioverter-defibrillator (ICD) use for primary prevention of SCD is reduced left ventricular ejection fraction. The significance of this parameter has been repeatedly demonstrated in large randomized studies. However, the use of a single indicator cannot solve the problem. In this review we present analysis of modern additional predictors of fatal arrhythmias which are available in clinical practice, as well as the perspective for further research of this highly important scientific, clinical, and social problem.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
