Key Points Question What is the self-perceived angina-specific health status before and after percutaneous coronary intervention (PCI) among patients without acute myocardial infarction in China? Findings In this cohort study of 1611 Chinese patients without acute myocardial infarction undergoing elective PCI, 27.5% had stable coronary artery disease and 72.5% had unstable angina. Of patients undergoing PCI for stable coronary artery disease, 25.7% had no reported angina symptoms at the time of the procedure, and patients with smaller clinical improvements in angina symptom burden at 1 year following PCI had significantly higher baseline Seattle Angina Questionnaire scores for all scales. Meaning These findings highlight the importance of ascertaining impairment from angina among patients without acute myocardial infarction prior to performing PCI.
