A spiroergometric test was performed in 31 males, on the 28th day following a nontransmural myocardial infarction (NTMI). The patients were distinguished in two groups on the basis of the clinical and ECGraphic response of this test. Group A: 20 subjects, aged from 32 to 59 (average 49.5). No patient of this group stopped the test for chest pain nor ischemic changes of the ECG. Group B: 11 subjects, aged from 39 to 63 (average 55,2). In every patient of this group the test was stopped because of anginal pain or ischemic changes of the ECG. Following the test, all the subjects performed a supervised rehabilitation program, arranged on the data of the evaluation test. The group A subjects increased their Maximal Work Capacity (MWC) to 27,7% and Total Work Performed (TWP) to 67%. No patient complained of chest pain nor depression of S-T segment nor arrhythmias during the ECG-monitored rehabilitation sessions. All the patients ended the training program and none showed angina pectoris nor ECGraphic ischemic changes in the final evaluation test. The group B subjects did not increase significantly their MWC nor TWP. Frequently these patients complained of chest pain or S-T depression or arrythmias during the ECG-monitored rehabilitation sessions. Of these 4 patients did not finish the training program: in 3 cases because of the onset of resting angina, in 1 case because of a new acute myocardial infarction. The remaining 7 patients showed ischemic changes of the ECG in the final evaluation test. These findings indicate that a spiroergometric test, performed 28 days later a NTMI, is able to discriminate two clinical patterns, conditioning the possibility of the cardiac rehabilitation. In particular, it appears to be contraindicated in patients of group B. These patients need a diagnostic search, including coronary angiographic procedure, in view of medical or surgical treatment.
