Abstract
Left ventricular (LV) diastolic dysfunction is an important contributor to many different cardiovascular diseases. LV diastolic dysfunction can manifest itself as slow LV relaxation, slow LV filling or high diastolic LV stiffness. Diastolic abnormalities have been described in the senescent heart, in heart failure with preserved ejection fraction (HFPEF), in diabetic cardiomyopathy, in aortic valve stenosis (AVS), in hypertrophic cardiomyopathy (HCM), as well as in Fabry disease (FD), however, exact cellular and molecular alterations behind the diastolic deterioration in these diseases are not yet completely characterized. Several studies thoroughly investigated altered cardiomyocyte function, changes of contractile myofilaments, extracellular collagen deposition and advanced glycation end products (AGEs) cross-linking in the background of diastolic dysfunction. These clinical and experimental data suggest that underlying mechanisms of LV diastolic dysfunction are divergent in different cardiac pathologies, therefore the present review aims to summarize mechanisms at the cellular level of diastolic abnormalities in various cardiovascular diseases.

Artificial Intelligence in Bioinformatics
Bioinformatics is an interdisciplinary field that analyzes and explores biological data. This field combines biology and information system. Artificial Intelligence (AI) has attracted great attention as it tries to replicate human intelligence. It has become common technology for analyzing and solving complex data and problems and encompasses sub-fields of machine ...read more
