RIGHT VENTRICULAR DIASTOLIC DYSFUNCTION: MECHANISM OF DEVELOPMENT, DIAGNOSIS AND PROGNOSTIC SIGNIFICANCE

Abstract

In patients with ischemic heart disease (IHD), the main focus is currently on the pathology of the left ventricle (LV), while the right ventricle (RV) is overlooked. This is logical, since, in IHD, as a result of damage to the left parts of the heart, their remodeling, dilatation and development of heart failure (HF) occur. However, the results of studies in recent years have shown that IHD, ischemia and myocardial infarction (MI) of the pancreas, are one of the main causes of pancreatic dysfunction. Thus, in patients with lower myocardial infarction, pancreatic pathology occurs in 41.1% of cases and is a predictor of mortality in late periods after myocardial infarction, associated with the occurrence of recurrent myocardial infarction and stent thrombosis [1,15]. In general, right ventricular dysfunction is considered to be one of the strongest independent predictors of prognosis after MI, even in the absence of RV MI [2], so it is important to diagnose this pathology as early as possible. In this regard, the assessment of RV diastolic function is considered more informative, which, on the one hand, is a marker of early or latent RV dysfunction [3, 4], and on the other hand, also has independent prognostic value [2,15].
