Abstract

We studied prognostic value of left ventricular (LV) diastolic dysfunction (DD) in relation to sudden cardiac death (SCD) after myocardial infarction (MI). We examined 603 patients in acute period of MI (including 551 with preserved LV systolic function and DD). Duration of follow-up was 1-7 years. According to data of Cox multifactorial regression analysis LVDD was not an independent prognostic factor. ut it increased SCD risk at the account of interrelationship with such predictors as ventricular rhythm disturbances, lowering of heart rate variability, and sensitivity of cardiochronotropic component of arterial baroreflex.
