Abstract

In Reply.—  Among those who have made a study of the issue, opinion is divided as to how much of the decline in cardiovascular mortality has resulted from an altered life-style and how much is a consequence of innovations in medical care. To provide a supportable answer, certain currently unavailable information is required. It is necessary to know whether the incidence (attack rate) has declined along with mortality; whether reinfarction rates have decreased; whether the ratio of sudden to nonsudden deaths has changed; and whether there has been a decrease in incidence of myocardial infarction following angina. Unfortunately, data on these points are sparse and inconsistent.The case for either improved treatment or risk-factor modification is difficult to sustain. A substantial part of coronary heart disease (CHD) mortality progresses from inapparent disease to death rather precipitously. Much of the premature coronary mortality comes on with little warning, in a population
