New perspectives on cardiovascular risk factors.
Atherogenic traits, living habits, signs of preclinical disease, and susceptibility all contribute to cardiovascular disease. High low-density lipoprotein is positively related to coronary heart disease, and high high-density lipoprotein is inversely related. Systolic or diastolic hypertension at any age in either sex contributes powerfully. The impact of diabetes is greater for women and varies with the number of accompanying risk factors. High-normal fibrinogen values further escalate risk of these atherogenic factors. An atherogenic life-style is typified by a diet excessive in fat, calories, and salt; sedentary habits; unrestrained weight gain; and cigarette smoking. Moderate alcohol use may be beneficial. Use of oral contraceptives beyond age 35 years and in conjunction with cigarette smoking predisposes one to thromboembolism. Type A behavior carries an increased risk, and men married to more highly educated women and to women in white-collar jobs are more vulnerable. Signs of preclinical ischemia include silent myocardial infarction, left ventricular hypertrophy on ECG, blocked intraventricular conduction, and repolarization abnormalities. Measures of innate susceptibility include a family history of early cardiovascular disease. Quantitative combination of risk factors provides optimal prediction, including persons with multiple marginal abnormalities. Preventive management should also be multifactorial and requires a commitment to behavior modification and alteration in life-style.
