[The clinical and diagnostic value of some hemodynamic indices for the assessment of silent ischemia in patients with low myocardial contractility].

During initial anesthesia, central and peripheral hemodynamic parameters were studied in 32 patients operated on for coronary heart disease (CHD). The patients were divided into 3 groups: 1) those with < 35% ejection fraction (EF) with postinfarct left ventricular (LV) aneurysm (PLVA); 2) those with > 35% EF with PLVA; 3) those with > 35% EF without PLVA. All the examinees were assigned as having NYHA functional class III-IV.
