Effect of Remote Ischemic Preconditioning on Troponin I in CABG
BACKGROUND: Elective open heart surgery is associated with troponin release in some cases due to myocyte necrosis. OBJECTIVES: The aim of this study was to measure cardiac troponin I (cTnI) preoperatively in elective CABG after remote ischemic preconditioning. METHODS: Twenty-eight patients were sel...

Sumario: | BACKGROUND: Elective open heart surgery is associated with troponin release in some cases due to myocyte necrosis. OBJECTIVES: The aim of this study was to measure cardiac troponin I (cTnI) preoperatively in elective CABG after remote ischemic preconditioning. METHODS: Twenty-eight patients were selected for elective CABG. They were randomized to receive remote ischemic preconditioning (induced by three 5-min cycles of inflation with a pneumatic tourniquet and 5-min deflation between inflation episodes as reperfusion). OUTCOMES: Primary outcomes were cardiac troponin I levels at 6 and 24 hours after the procedure, and the secondary outcomes included creatine phosphokinase, lactate dehydrogenase, and serum creatinine levels. Hemodynamic changes were evaluated between the treatment and control groups. RESULTS: Cardiac troponin I at 6 hours after preconditioning was significantly lower compared to the control group (P = 0.036), and after 24 hours, there was still a significant difference between the two groups (P < 0.05). CONCLUSIONS: Remote ischemic preconditioning reduces ischemic biomarkers during coronary artery bypass graft and attenuates procedure-related cardiac troponin I release and eventually reduces cardiovascular events such as myocardial infarction, chest pain, and hemodynamic changes after cardiac surgery. |
