Prognosis of symptomatic coronary artery disease in young adults aged 40 years or less.
The clinical course and coronary angiographic features of symptomatic coronary artery disease (CAD) in patients younger than 40 years old are described with particular emphasis on the prevalence of myocardial infarction and the degree of diminished functional capacity. Eighty-five patients with CAD proven by coronary angiography were studied. There were 73 men and 12 women aged 27 to 40 years. Fifty-nine patients presented with acute myocardial infarction, most of whom denied previous chest pain, and 14% (12 patients) presented with less acute chest pain syndromes. Coronary angiography was performed in all patients, and greater than or equal to 70% luminal diameter narrowing was considered significant. Coronary angiographic findings reveal 51% with 1-vessel CAD, 31% with 2-vessel and 19% with 3-vessel. Subsequently, 23 patients had coronary artery bypass graft surgery, 7 underwent angioplasty and 55 were treated medically. Follow-up for a mean of 3 years revealed only 1 death and 4 subsequent hospital admissions for cardiac events. Fifty-three percent of the patients are entirely pain free, and only 4 (5%) have significant symptoms of angina pectoris. Although 15 (18%) are not employed regularly, the remainder work full- or part-time, or plan to work in the near future. These data suggest that the short-term prognosis and functional status of young patients with CAD is excellent.
