Factors associated with right ventricular dilatation in coronary artery disease patients with prior q-wave myocardial infarction

Factors associated with right ventricular (RV) dilatation in patients with prior Q-wave myocardial infarction (MI) have been determined. Out of 16839 patients from «Register of performed coronary angiography» we selected those with prior Q-wave MI who had no congenital heart disease: 1263 patients without RV dilatation and 99 patients with RV dilatation. There were more males in the group with RV dilatation (97.0 vs 89.6%, p = 0.018). Mean body mass index (BMI) was higher in this group (31.0±5.1 vs 29.4±4.6 kg/m 2, p = 0.003). Patients with RV dilatation more often had a higher New-York Heart Association (NYHA) functional class (III/IV - 50.5 vs 17.4%) and arrhythmias (45.5 vs 17.8%, both p2). This group often demonstrated a reduced LV systolic function (71.7 vs 32.9%) and significant mitral regurgitation (52.5 vs 12.4%, all p
