BACKGROUND: As percutaneous coronary intervention (PCI) is most commonly performed for relief of angina, it is important to identify factors associated with recurrence of anginal symptoms.
METHODS: We examined symptoms at 1-year follow-up in 1755 consecutive NHLBI Dynamic Registry patients who underwent PCI in the setting of symptoms or acute infarction.
RESULTS: At 1-year follow-up, 26% of patients reported angina in the previous 6 weeks. Younger patients and females reported more symptoms. History of coronary artery bypass graft (CABG) or PCI, prior myocardial infarction (MI), diabetes, graft disease, and extensive coronary artery disease (CAD) (>4 significant lesions) were also associated with follow-up angina. Patients receiving stents reported less angina (24% vs 29%, P <.05). Completely revascularized patients and those with residual single-vessel disease had comparable 1-year angina rates (23% both subgroups), while 32% of patients with residual multivessel CAD reported symptoms. Patients undergoing repeat PCI during follow-up reported more 1-year angina than others (34% vs 24%, P <.001), whereas those undergoing CABG after post-PCI hospitalization had less symptoms (15% vs 26%, P <.05). After adjustment for baseline symptom status and outcome of index PCI, residual CAD, and reintervention during follow-up, patient characteristics significantly predictive of angina included female sex, age <62 years, and prior MI.
CONCLUSIONS: While approximately three quarters of patients receiving PCI are angina-free at 1 year, females continue to have more symptoms, as do other subgroups including patients with history of MI or previous intervention. As these symptoms are associated with self-reported activity and quality of life limitation, evaluations of PCI should include angina as a key follow-up outcome.
