Relation of Occupation to Presence or Absence of Coronary Artery Disease: An Angiographic Study
Suite 10-D University of South Alabama Medical Center 2451 Fillingim Street Mobile, AL 36617
To determine the relation of occupation to the presence or absence of coronary artery disease (CAD) and cardiovascular risk factors, the authors compared the occupations of a series of 116 consecutive patients who underwent coronary angiography and were found to have normal or near-normal coronary arteries (<30% stenosis of all major coronary arteries) with those of a series of 116 patients with moderate to severe CAD (

60% stenosis of one or more major coronary artery). The usual lifetime occupational status of each study participant was classified as sedentary, intermediate, or strenuous. The presence of the usual cardiovascular risk factors in the patients was also recorded. There was no significant difference in the frequency of the three occupational categories between the two groups (those with or without CAD) when subjects of all ages were considered or when subjects less than 40 years or more than 60 years old were consid ered. However, the results indicate that among 40-60-year-old individuals CAD occurred significantly more frequently in those engaged in strenuous occupations than in those engaged in sedentary occupations. Cardiovascular risk factors occurred significantly more frequently in patients with CAD than in those with normal coronary arteries and in those engaged in strenuous occupations compared with those in sedentary occupations.
