    Abstract:
    The essential goal of medical treatment following myocardial infarction with left ventricular dysfunction must be the prevention of secondary cardiac failure. The existence of left ventricular dysfunction, in particular when it is not accompanied by clinical cardiac failure, is a virtually formal indication for beta-blocker treatment after an infarction. Beta-blockers with intrinsic sympathomimetic activity (ISA) are possibly better tolerated in this context. However, experience shows that cardiologists and general practitioners often remain reluctant to prescribe beta-blockers whenever left ventricular function is impaired. Converting enzyme inhibitors decrease the risk of onset of secondary cardiac failure, reduce sudden deaths by ventricular arrhythmias, reduce recurrences of myocardial infarction or unstable coronary insufficiency, and more generally reduce overall and cardiovascular mortality. This is a class effect. While there is no urgency to prescribe them during the acute phase, it is generally considered that it is extremely useful to give them fairly quickly, i.e. during the first 72 hours. At the end of the hospital phase, around two weeks, it is desirable, whenever possible, to prescribe a dose of the order of 75 mg/day of captopril or 2.5 mg/day of ramipril. The administration of aspirin can be considered virtually routine. Oral anticoagulants are desirable in the presence of a large akinetic pocket, a frequent starting point of thrombosis and/or systemic emboli, or in the presence of atrial fibrillation. Digitalis/diuretic treatment does not appear to be indicated at this stage. Other types of anti-ischemic treatment are not theoretically indicated as a matter of principle at this stage in the absence of residual ischemia.(ABSTRACT TRUNCATED AT 250 WORDS)
