Incidence and Predictors of Cardiac Markers Elevation after Coronary Intervention

Objectives-This study evaluated the incidence and predictors of CK-MB and troponin elevation after successful coronary intervention. Background- CK-MB and troponin elevation after coronary intervention correlate with late cardiac events and survival.1 2 19 2 4 We investigated the incidence and predictors of CK-MB and troponin elevation in patients who underwent percutaneous coronary intervention in Rajaie Cardiovascular, Medical and Research Center. Results CK-MB and troponin elevation was detectable in 203 (70%) patients. Predictors of cardiac enzyme elevation were hyperlipidemia, functional class, and smoking. There were no in-hospital adverse events in the CK-MB and troponin elevation group. Conclusion- Cardiac enzyme elevation after coronary intervention was detected in 70% of all our patients and was more common in diffuse atherosclerosis hyperlipidemia, smoking, and high functional class. Enzyme elevation was observed even in the absence of discernible procedural complications, and early discharge of patients with CK-MB and troponin elevation is safe. Mid-term survival of patients with CK-MB and or troponin elevation was similar to those with normal enzymes
