Acute myocardial infarction; a discussion of certain controversial issues

As a general rule, it is not believed possible to classify patients with acute myocardial infarction as to the future severity of their illness at the time of the initial examination. However, classifications are possible from complete clinical data of the first few days with regard to the predicted mortality rates. Whether to manage the patient in the hospital or at home depends on the community facilities. The patient should be in bed for a period of two to three weeks if unquestioned infarction has occurred. The main avenue of investigation as to lowering of mortality needs to be directed toward the prevention of heart failure or sudden unexpected death probably related to arrhythmia. If the patient is hospitalized and laboratory facilities are available, anticoagulant therapy can be safely and effectively carried out without undue risk or prohibitive increase in the cost of management. The experience of the author and his colleagues has led to the belief that anticoagulants given routinely to patients with myocardial infarction are effective in decreasing the incidence of thromboembolic complications.
