Association of Coronary Artery Dominance With Long-term Outcomes in Female Patients With Suspected Ischemia but Nonobstructive Coronary Artery Disease

Coronary artery dominance, referring to the arterial supply of the posterior descending artery (PDA), significantly impacts clinical outcomes in cardiac patients. Typically, the PDA originates from the right coronary artery in the right-dominant pattern, the most common form found in individuals. The less prevalent left-dominant type sees the PDA deriving from the left circumflex artery, and balanced dominance involves both the right coronary artery and left circumflex artery supplying the PDA. Notably, left coronary dominance has been found to be linked to adverse outcomes in patients with acute coronary syndrome who undergo percutaneous coronary interventions.
