Percutaneous Intervention and Coronary Artery Bypass Graft Surgery Instable Angina

Stable angina pectoris represents a prevalent and clinically significant manifestation of coronary artery disease. Despite advances in medical therapy, many patients continue to experience symptoms that necessitate revascularization. Among the current strategies, percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) are widely used, both aiming to restore myocardial perfusion impaired by coronary artery stenosis or occlusion. This article provides a comprehensive overview of stable angina’s clinical presentation, diagnostic evaluation, and current treatment options. Emphasis is placed on appropriate patient selection for each revascularization modality, including the application of the SYNTAX II score and other clinical parameters. Special populations such as diabetic, renal failure, and heart failure patients are also addressed, in line with contemporary evidence and guidelines.
