Abstract
Background: Previous studies documenting underutilization of angiotensin‐converting enzyme inhibitors (ACEIs) in acute myocardial infarction (AMI) have been limited to Medicare populations.
Hypothesis: This study examines ACEI prescription rates and predictors in a community sample of hospitalized patients with AMI.
Methods: The charts of 1163 community patients with AMI, prospectively identified at admission between January 1, 1994, and April 30, 1995, were reviewed.
Results: Only 64 of 158 (40%) patients considered ideal candidates for ACEI prescription were discharged with a prescription for an ACEI. In a multivariate logistic regression model, prior ACEI utilization [adjusted odds ration (OR) = 3.26; 95% confidence interval (CI) = 2.05–5.20], presence of congestive heart failure (OR = 2.33; CI = 1.50–3.61) and black race (OR = 2.20; CI = 1.34–3.64) were identified as positive predictors of ACEI prescription. Conversely, lack of left ventricular ejection fraction (LVEF) measurement (OR = 0.46; CI = 0.28–0.75), LVEF > 40 (OR = 0.27; CI = 0.18–0.40), and acute renal failure (OR = 0.08; CI = 0.01–0.44) were negative predictors. Women were also less likely to be discharged with an ACEI prescription (OR = 0.71; CI = 0.48–1.05). Furthermore, women were significantly less likely to have LVEF measured prior to discharge than were males (77 vs. 85%, p = 0.001).
Conclusion: This study underscores the need for improvement in the utilization of ACEI in eligible patients with AMI. It also identifies opportunities for improvement in prescription rates, especially in women.
