Relation between initial treatment strategy in stable coronary artery disease and 1-year costs in Ontario: a population-based cohort study.

Background: Cardiovascular disease is costly, and annual expenditures are projected to increase. Our objective was to examine the variation in patient-level costs and identify drivers of cost in patients with stable coronary artery disease.

Methods: In this retrospective cohort study using administrative databases in Ontario, Canada, we identified all patients with stable coronary artery disease after index angiography between Oct.

Management and outcomes of non-ST elevation acute coronary syndromes in relation to previous use of antianginal therapies (from the Canadian Global Registry of Acute Coronary Events [GRACE] and Canadian Registry of Acute Coronary Events [CANRACE]).

Randomized trials have established the efficacy of antianginal medications in the treatment of chronic stable coronary disease. Using data from the Global Registry of Acute Coronary Events (GRACE) and Canadian Registry of Acute Coronary Events (CANRACE), we examined the temporal trends in antianginal use (beta blockers, calcium antagonists, and nitrates) before non-ST-elevation acute coronary syndrome presentation from 1999 to 2008 in 10,019 patients. The relationships among previous antianginal use, clinical characteristics on presentation, and in-hospital management and outcomes were examined.
