Percutaneous Intervention and Coronary Artery Bypass Graft Surgery Instable Angina
Gulana Agayeva* and Narmin Islamova
Abstract
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.
