Abstract

Right cardiac catheterization, serial determination of creatine phosphokinase (CPK) and of CPK-MB activities, and precordial 35-lead ECG mapping were performed in 17 consecutive patients with a first anterior acute myocardial infarction (AMI) within 6 hours of the onset of symptoms. Left ventricular function as determined by the stroke index (SI, ml/m2) to mean pulmonary capillary wedge pressure (PCWP, mmHg) ratio inversely correlated either with the total CPK and CPK-MB released and with peak enzymatic activity, or with the entity of early (6th hour ECG) ST-segment elevation. Conversely, a direct correlation was found between the SI/PCWP ratio and the ratio of R to Q + S waves from late (48th hour) ECG. Residual left ventricular function after a first anterior AMI can therefore be estimated noninvasively in the individual patient by early precordial ECG mapping and by peak enzymatic activity.
