ABSTRACT
SUMMARY OBJECTIVE:
Severe inflammation is reportedly associated with subsequent cardiovascular events, including in patients with coronary artery disease. This study aimed to examine the prognostic value of systemic immune-inflammation index and determine mortality and clinical outcomes in patients with chronic coronary total occlusion.METHODS:
Our study evaluated 366 consecutive coronary total occlusion patients. The clinical end points were all-cause mortality and major adverse cardiovascular events, which include target vessel revascularization, myocardial infarction, and cerebrovascular events during 105 months follow-up.RESULTS:
The study findings showed 59 (16.1%) all-cause death, 22 (6%) target vessel revascularization cases, 32 (8.7%) myocardial infarction cases, and 13 (3.6%) cerebrovascular events cases, with a median follow-up of 49 months (26-74). Multivariate logistic regression analysis showed that systemic immune-inflammation index was not associated with target vessel revascularization, myocardial infarction, and cerebrovascular events. Multivariate Cox regression analysis found systemic immune-inflammation index to be associated with all-cause death. Kaplan-Meier analysis showed a lower survival rate and myocardial infarction-free survival time in patients with higher systemic immune-inflammation index scores.CONCLUSION:
Although systemic immune-inflammation index is a preferable tool for the detection of mortality, it failed to give adverse outcomes. Larger multicenter studies are thus warranted to investigate the effect of systemic immune-inflammation index on clinical outcomes.
