[Fighting the coronary artery disease epidemic in Chile: caveats in the control of cardiovascular risk factors].
In this issue of the journal Lanas et al report an estimation of population attributable risk (PAR) for myocardial infarction (MI) derived from different risk factors in Chile. Cigarette smoking, dyslipidemia and hypertension accounted for 71% of total PAR. Mortality from MI has decreased in Chile, but epidemiologic surveys carried out in different hospitals across the country, strongly support that most of this effect comes from better treatment of MI. Recent changes in public health policies, favoring the treatment of hypertension and diabetes may help control cardiovascular morbidity and mortality. However, a really significant impact will be obtained when the development of the disease may be halted. To evaluate this possibility, newer methods to diagnose atherosclerosis non invasively may come to our rescue. On the other hand, pharmacologic treatment of dyslipidemia and hypertension continue to offer the most powerful way to decrease levels of cardiovascular risk factors. According to current knowledge, wise balance of non pharmacologic and pharmacologic means of primary prevention, with due respect for ethic aspects, is the most effective way to curve the epidemic of coronary artery disease in Chile.
