The clinical implications of increased cyclophilin A levels in patients with acute coronary syndromes

► Was CyPA level related to the stability of coronary atherosclerotic plaque? ► CyPA levels in ACS were significantly higher than those in SA and controls. ► Soluble CyPA was correlated to complex coronary stenoses and MMPs. ► CyPA may be a valuable marker for predicting the severity of ACS.
