Abstract

40 patients, showing a hyperkinetic response during an ergometric test 30 days after a myocardial infarction, were randomly divided into 4 groups consisting of 10 subjects and treated as follows. Group M: metoprolol 200 mg/die; Group P: propranolol 160 mg/die; Group A: amiodarone 400 mg/die; Group V: verapamil 240 mg/die. A new ergometric test was performed 15 days later. In every case the total work performed was higher in the second test than in the first one. Lowering of the maximal double product faced increasing of the total work performed. Submaximal HR, sBP and double product was found to be reduced after all the 4 treatments. These data confirm that pharmacological treatment is useful to readjust the cardiac work to the total external work. Two patients belonging to Groups M and P stopped the second test due to signs of pump failure. The author's conclusions are: the drugs tested here are useful to reduce the hyperkinetic response to exercise after myocardial infarction. Nevertheless, metoprolol and propranolol hold the risk of effort cardiac failure. On the contrary, verapamil and amiodarone do not seem to present this risk.
