Peripheral arterial disease and multisite atherosclerosis in patients undergoing percutaneous coronary intervention.

Key Points Atherosclerosis is a systemic disease and frequently coronary artery disease is intertwined with peripheral arterial disease (PAD). This large study showed that PAD and its extension (multisite atherosclerosis) negatively affects the risk of in‐hospital mortality in patients with coronary artery disease undergoing PCI. PAD status and its extension in the principal vascular territories should be carefully assessed during hospitalization for coronary revascularization and should be regarded as important risk factors.
