AIMS: To examine combined and sex-specific temporal changes in risks of adverse cardiovascular events and coronary revascularization in patients with chronic coronary syndrome undergoing coronary angiography.

METHODS: We included all patients with stable angina pectoris and coronary artery disease examined by coronary angiography in Western Denmark from 2004 to 2016. Patients were stratified by examination year interval: 2004-2006, 2007-2009, 2010-2012, and 2013-2016. Outcomes were two-year risk of myocardial infarction, ischemic stroke, cardiac death, and all-cause death estimated by adjusted incidence rate ratios using patients examined in 2004-2006 as reference.

RESULTS: A total of 29,471 patients were included, of whom 70% were men. The two-year risk of myocardial infarction (2.8% versus 1.9%, adjusted incidence rate ratio 0.65, 95% CI 0.53-0.81), ischemic stroke (1.8% versus 1.1%, adjusted incidence rate ratio 0.48, 95% CI 0.37-0.64), cardiac death (2.1% versus 0.9%, adjusted incidence rate ratio 0.38, 95% CI 0.29-0.51), and all-cause death (5.0% versus 3.6%, adjusted incidence rate ratio 0.65, 95% CI 0.55-0.76) decreased from the first examination interval (2004-2006) to the last examination interval (2013-2016). Coronary revascularizations also decreased (percutaneous coronary intervention: 51.6% versus 42.5%; coronary artery bypass grafting: 24.6% versus 17.5%). Risk reductions were observed in both men and women, however, women had a lower absolute risk.

CONCLUSION: The risk for adverse cardiovascular events decreased substantially in both men and women with chronic coronary syndrome from 2004 to 2016. These results most likely reflect the cumulative effect of improvements in the management of chronic coronary artery disease.
