ABSTRACT
BACKGROUND:
Despite the important role of some haematological parameters in tendency to thrombosis is known, their relationship with long-term stent thrombosis (ST) remains unclear.AIMS:
This study aimed to investigate the association between the mean platelet volume (MPV) to platelet count (PC) ratio and long-term ST and mortality in patients with ST-segment-elevation myocardial infarction (STEMI) treated successfully by primary percutaneous coronary intervention (pPCI).METHODS:
In a retrospective cohort study, according to their baseline MPV/PC ratios, 3667 consecutive STEMI patients undergoing pPCI were divided into three groups tertile 1 (T1) (n = 1222, 0.357 ≥ MPV/PC ≥ 0.043), tertile 2 (T2) (n = 1222, 0.033 < MPV/PC < 0.043) and tertile 3 (T3) (n = 1223, 0.009 ≤ MPV/PC ≤ 0.032). Patients were followed up with for 5 years, focusing on ST and all-cause mortality outcomes.RESULTS:
Patients with T1 displayed a greater 5-year ST rate, including a 2.76-fold greater (95% confidence interval 1.68-10.33) rate than that of patients with T3, who had the lowest rates and were used as the reference group. Meanwhile, the 5-year mortality rate was similarly higher among patients with T1 by 1.72 times (95% confidence interval 1.33-2.22) relative to that among patients with T3. These significant relationships persisted even after adjustment for all confounders.CONCLUSION:
We found that higher MPV/PC ratios were associated with long-term ST and mortality. The MPV/PC ratio may constitute both a rapid and an easily obtainable parameter for identifying reliably high-risk patients who have undergone pPCI.Palavras-chave
