Changing presentation of coronary heart disease in an inpatient population within the U.S. military health care system



Changing presentation of coronary heart disease in an inpatient population within the U.S. military health care system



Military Medicine 158(9): 598-603



This study examines the changing presentation of coronary heart disease (CHD) in an inpatient population at Brooke Army Medical Center. The specific objectives of the study were to examine the presentation of CHD in a population unbiased by diagnosis-related group (DRG) reimbursements and to assess the importance of unstable angina and prior history of disease in the presentation of CHD. One thousand fifteen discharges in 1985 and 1,304 discharges in 1990 with the diagnosis of CHD were reviewed by cardiologists for evidence of symptomatic heart disease at the time of hospitalization. Forty percent of these charts were accepted into this study. The presentation rates of CHD were 1% with sudden death, 26% with myocardial infarction, 64% with angina, and 9% with congestive heart failure (CHF). During the study period, stable angina, Q-wave infarctions, and the myocardial infarction case fatality rate decreased (p < 0.05) and CHF and non-Q wave infarcts increased (p < 0.001). However, unstable angina was the most common presentation of CHD, and differences (p < 0.05) were noted in the presentation of CHD in patients with and without a prior history of disease. This study demonstrates the significance of unstable angina and prior history of CHD in an environment free of bias from DRG reimbursements.
