  • Title: [Recommendations for secondary prevention of the clinical coronary cardiopathy].
    Journal: Rev Esp Cardiol; 1985; 38(1):14-20. PubMed ID: 2858911.
    Abstract:
    These recommendations for secondary prevention of clinical coronary cardiopathy are the result of a symposium attended by 46 experts belonging to the councils on arteriosclerosis, clinical cardiology, epidemiology, and prevention and rehabilitation of the International Society and Federation of Cardiology. Secondary prevention of coronary cardiopathy refers to measures designed to prevent deterioration or death in patients with clinical manifestations of coronary cardiopathy. Such measures in addition to drugs include health actions that may improve the status of various coronary risk factors: the patient's life style should stress maintenance of proper weight, regular physical exercise, reduction of saturated fats and cholesterol in the diet, and elimination of smoking and excessive alcohol consumption. It is considered reasonable to control hypertension through the most innocuous means possible, but findings of the few existing controlled studies of effects of treatment of hypertension in coronary cardiopathy are complex. Drug treatment may be necessary for most patients, but nondrug measures should be added when possible. Various proofs including results of some controlled studies justify the recommendations for reducing elevated levels of serum cholesterol and low density lipoprotein cholesterol through dietary measures. Optimum plasma cholesterol levels are 5.2 mmol/1 or less, and the upper limit is 5.7 mmol/1. The rules for secondary prevention are the same for diabetics as for nondiabetics, but some special precautions are necessary in diabetics. Habitual and vigorous physical activity has been associated with a decline in the incidence of coronary cardiopathy in different population studies, although there has been no demonstration that exercise can alter the progression of atherosclerosis or improve collateral circulation. Stress should be recognized as a risk factor and included in secondary prevention, but the concept that stress is the key risk factor in coronary events is in conflict with a large body of scientific evidence. Oral contraceptives (OCs) tend to increase boood pressure and weight as well as serum triglyceride levels, and to reduce glucose tolerance and high density lipoprotein cholesterol in some formulations. OCs also affect the integrity of the vascular endothelium and alter blood coagulation, fibrinolysis, and platelet function. These thrombogenic changes are intensified with age, especially after 35, and with smoking. OCs are innocuous in women under 35 with no history of venous or arterial disease or pulmonary embolism and who have normal blood pressure and serum cholesterol levels. Patients using OCs should control their blood pressure and weight and be alert to any symptoms of thrombotic episodes. The risk/benefit ratio of longterm estrogen treatment in meno- and postmenopausal women with coronary cardiopathy has not yet been established. Apart from 1 study in primates, there is no evidence that vasectomy should be considered either indicated or contraindicated for coronary patients. Beta blockers, platelet function inhibitors, anticoagulants, and other drugs are under active study for secondary prevention of coronary cardiopathy.
