BACKGROUND: Platelets are important in the pathogenesis of atherosclerotic complications. Higher mean platelet volume (MPV) levels are related to greater in vitro aggregation, and have been identified as an independent risk factor for myocardial infarction, and for death or recurrent vascular events.

AIM: To determine the relationship between MPV and the coronary collateral circulation.

METHODS: The sample consisted of 96 patients with coronary artery disease, and patients were separated into two groups according to their poorly developed or well-developed collateral circulation. Coronary collateral vessels were analyzed according to the Cohen and Rentrop grading system of 0-3.

RESULTS: All analyses were conducted using SPSS 11.5 (SPSS for Windows 11.5, Chicago, IL, USA). Continuous variables were expressed as mean ± SD, and categorical variables were expressed as percentages. Comparison of categorical and continuous variables between the group with well-developed coronary collateral vessels and the group with poorly developed vessels was performed using the chi-squared test and independent samples t-test, respectively. Platelet count and MPV values were similar between the two groups.

CONCLUSIONS: Our study found that MPV levels are not related to coronary collateral circulation.
