Case reports of co-occurring variant angina and syndrome X support shared mechanisms; leaves open confirmation in larger cohorts.
Case Report (n=3)
The simultaneous occurrence of variant angina and cardiac syndrome X in the same patients suggests shared pathogenetic mechanisms between macrovascular and microvascular coronary dysfunction.
Infusino et al. (2009) conducted a case report in Prinzmetal's variant angina and cardiac syndrome X (n=3). Simultaneous variant angina and cardiac syndrome X was evaluated on Clinical manifestations of functional macrovascular and microvascular coronary artery abnormalities. Three patients exhibited simultaneous angina episodes typical of both variant angina and cardiac syndrome X, suggesting common pathogenetic factors for macrovascular and microvascular abnormalities.
