Antianginal medications and long-term outcomes after elective catheterization in patients with coronary artery disease.

Journal Article (Journal Article)

BACKGROUND: Antianginal medications are a class I recommendation by the American College of Cardiology/American Heart Association guidelines for stable ischemic heart disease. We sought to better understand guidance in drug selection and real-life outcomes of antianginal medication use. HYPOTHESIS: In patients with stable ischemic heart disease, antianginal medications lower mortality. METHODS: We evaluated 5608 patients with obstructive coronary artery disease (CAD) on elective cardiac catheterization with follow-up through self-administered questionnaires. Patients were classified as being prescribed a particular medication if they received that medication at index catheterization, or within 3 months postcatheterization. The association between antianginal medication use and outcomes was evaluated using Cox proportional hazards models. RESULTS: Compared with the 11% not prescribed any antianginal medication, patients prescribed antianginal medication were more likely to be older and female; have a history of hypertension, diabetes mellitus, peripheral vascular disease, or 3-vessel CAD; have lower adjusted mortality (hazard ratio [HR]: 0.75, 95% confidence interval [CI]: 0.63-0.89); and experience mortality or myocardial infarction (HR: 0.83, 95% CI: 0.71-0.98). Compared with patients not taking β-blockers (17%), those taking β-blockers had a lower risk of mortality (HR: 0.76, 95% CI: 0.66-0.88). Patients prescribed calcium channel blockers or long-acting nitrates had a higher risk of mortality compared with nonusers (HR: 1.16, 95% CI: 1.04-1.29; HR: 1.20, 95% CI: 1.08-1.34; respectively). CONCLUSIONS: Antianginal medications are not universally prescribed among obstructive CAD patients; nonuse was associated with higher mortality. For CAD patients with or without prior myocardial infarction, β-blockers were associated with improved long-term survival.
