Effects of Curcuminoids on Myocardial Injury After Percutaneous Coronary Intervention.

The rise of cardiac troponin post-percutaneous coronary intervention (PCI) is associated with a high risk of long-term cardiovascular events. Previous studies have shown that curcuminoids decreased myocardial injury post-coronary bypass graft surgery through anti-oxidant and anti-inflammatory effects. We sought to examine whether curcuminoids could prevent PCI-related myocardial injury. One-hundred enrolled patients receiving elective PCI were randomized to obtain curcuminoids or placebo 4 g/day at least 1 day before and after the scheduled PCI. Cardiac troponin-T and 12-lead electrocardiogram were evaluated before PCI and at 24 and 48 h post-PCI. The definitions of PCI-related myocardial injury and myocardial infarction were in line with the third universal definition of myocardial infarction. Baseline characteristics of patients and procedures did not differ between the curcuminoids and placebo groups. The mean age was 63.9 ± 10.8 years. The incidence of PCI-related myocardial injury was not different between curcuminoids and placebo groups (32% vs. 38%,  = .675). The peak high-sensitive cardiac troponin T levels after PCI were not different between the curcuminoids and placebo groups (201.0 ± 547.0 ng/L vs. 187.0 ± 703.9 ng/L respectively,  = .912). Further, the high-sensitive C-reactive protein levels post-PCI were similar in patients receiving curcuminoids and placebo (7.2 ± 18.8 mg/dL vs. 6.6 ± 17.5 mg/dL, respectively,  = .873). We found that short-term treatment with curcuminoids did not reduce the occurrence of PCI-related myocardial injury. We did not observe the role of anti-oxidative and anti-inflammatory effects of curcuminoids in the PCI-related myocardial injury.
