Dear Editor, I have read with great interest the recently published article by Urbanowicz et al. [1]. This study aimed to explore the possible dependence on mean platelet volume (MPV) and postoperative percutaneous coronary interventions (PCI) risk in patients with complex coronary artery disease undergoing coronary artery bypass grafting in off-pump technique (OPCAB). The authors reported that MPV can be regarded as a simple marker of PCI risk following OPCAB procedures. The preoperative MPV indicates the individual tendency for worse prognosis more than procedure dependence. However, there are major limitations in MPV measurement. In this study, MPV measurement technique is not described. The mean platelet volume is dependent on a number of variables, including time of analysis after venepuncture, method of analysis, anticoagulant used and specimen storage temperature. Although EDTA is traditionally used and recommended for samples destined for blood counting, it is well known that platelets collected into EDTA anticoagulants undergo time-dependent platelet swelling and activation [2, 3]. The retrospective nature of the study leads to a significant problem because the MPV results could not be standardized. This study has no exclusion criteria. However, there are many diseases and medications affecting MPV levels [4] Therefore, MPV-based analysis results can be misleading.
