Value of maximal exercise tests in risk assessment of primary coronary heart disease events in healthy men. Five years' experience of the Seattle heart watch study.

摘要: Abstract Of 2,365 clinically healthy men who participated in the exercise testing unit of Seattle Heart Watch, follow-up by annual mail questionnaires identified 47 persons (2 percent) experienced primary coronary heart disease events. The mean period (± standard deviation) was 5.6 ±1.4 years. rates such events higher 55 or more years age than younger men. A count conventional risk factors at time initial examination associated with increased 5 year probability However, univariate analysis individual (positive family history, hypertension, smoking, hypercholesterolemia) did not show a significant increase probability. Four variables obtained from response to symptom-limited maximal were significantly subsequent These predictors chest pain during exertion, duration less 6 minutes Bruce protocol, failure attain least 90 percent age-predicted rate and ischemie S-T segment depression. When are both considered asymptomatic men, small group (1 total population) had highest (0.33). This one two identified. those but 0.015. Forty-one population no this 0.01. Exercise predictive value latter group.
