Kurtul A, et al. – In acute coronary syndrome (ACS) patients, link between admission mean platelet volume-to-lymphocyte ratio (MPVLR) levels and development of contrast–induced acute kidney injury (CI–AKI) following percutaneous coronary intervention (PCI), was investigated. Findings demonstrated a strong and independent association of admission MPVLR levels with the development of CI–AKI following PCI in these subjects.
