Right ventricular dilatation in patients with coronary heart disease without myocardial infarction: According to the data of the Coronary Angiography Surgery Registry

Abstract

Aim. To identify factors associated with right ventricular (RV) dilatation in patients with coronary heart disease (CHD) without prior myocardial infarction (MI). Subjects and methods. Out of 16 839 patents from the Coronary Angiography Surgery Registry, the investigators selected patients with >75% stenosis in at least one coronary artery without acute or prior MI: 75 patients with echocardiographically detected RV dilatation and 1134 without RV dilatation. Results. Among the patients with RV dilatation, there were more men (92% versus 80.2%; p=0.012). In this group, the mean body mass index (BMI) was higher (31.7±5.2 kg/m2 versus 30.1±4.7 kg/m2; р=0.019); there was more commonly higher NYHA functional class (FC) (III) chronic heart failure (CHF) (22.2% versus 12.5%; p=0.002), clinically relevant mitral regurgitation (29.4% versus 4.0%; all рs
