| Abstract: | PurposeData comparing the clinical benefits of medical treatment with those of percutaneous coronary intervention (PCI) in an elderly population with angina pectoris are limited. Therefore, we evaluated the efficacy of elective PCI versus optimal medical treatment (OMT) in elderly patients (between 75 and 84 years old) with angina pectoris.ResultsMajor adverse events occurred in 5 patients (5.6%) of the PCI group and in 17 patents (19.5%) of the OMT group (p=0.015). There were no significant differences between the PCI group and the OMT group in cardiac death hazard ratio (HR) for the PCI group 0.454; 95% confidence interval (CI) 0.041–5.019, p=0.520], myocardial infarction (HR 0.399; 95% CI 0.039–4.050, p=0.437), or stroke (HR 0.919; 95% CI 0.057–14.709, p=0.952). However, the PCI group showed a significant preventive effect of the composite of major adverse events (HR 0.288; 95% CI 0.106–0.785, p=0.015) and against the need for coronary revascularization (HR 0.157; 95% CI 0.035–0.703, p=0.016).ConclusionElective PCI reduced major adverse events and was found to be an effective treatment modality in elderly patients with angina pectoris and significant coronary artery stenosis, compared to OMT. |
