Abstract

Objectives

To determine the effect of mean platelet volume (MPV) to platelet count (PC) ratio on postoperative poor outcomes, early mortality and long-term survival rate in patients undergoing CABG.

Methods

Between February 2016 and September 2018, all patients undergoing CABG in our department were retrospectively reviewed. A total of 213 consecutive patients were included in the study.

Results

Mean age was 61.5 ± 9.7 years and mean follow-up of all patients was 1.4 ± 0.5 years. All patients were divided into two groups as high and low MPV/PC ratio in terms of 3.825 of cut-off point. 72 patients had a high MPV/PC ratio, whereas, 141 patients had low MPV/PC ratio. The rates of reoperation for early vein-graft occlusion, low cardiac output syndrome and respiratory complication were significantly higher in group 1 (p = 0.03, 0.04 and 0.01). The mean hospital length of stay was higher in group 1 (p = 0.03). MPV/PC ratio for reoperation for early vein-graft occlusion; MPV and ejection fraction for low cardiac output syndrome; hyperlipidemia, chronic renal failure history and MPV/PC ratio for sepsis; male gender, CRF history and CPB time for atrial fibrillation; age, congestive heart failure history, myocardial infarction history and CPB time for the early mortality were found to be independent predictors. Peripheral arterial diseases, USAP and MPV/PC ratio were found to be independent predictors for the late mortality.

Conclusions

A high MPV/PC ratio is associated with early vein-graft occlusion and poor postoperative outcomes in the early period after CABG. Furthermore, it has a negative effect on late survival.
