Magnified Risks From Cigarette Smoking for Coronary Prone Families in Utah

AUTOR(ES)
RESUMO

The contribution of currently accepted risk factors to the familiality of early coronary heart disease (CHD) is poorly understood. In a telephone and mail survey, risk factor and disease morbidity and mortality data were collected from 100 proband and 185 control families encompassing about 40,000 person-years of experience. Probands were white married men who had died of CHD by age 45. There was a threefold increase in CHD incidence among first-degree relatives of probands compared with control families. In all, 67% of probands had at least one first-degree relative with early CHD, and 29% had two or more first-degree relatives with early CHD compared with 8% of the control families with two or more cases of early CHD.
