Objectives: Hemogram parameters such as mean platelet volume (MPV), neutrophil/lymphocyte ratio (NLr), red cell distribution width and platelet distribution width are widely used inflammatory indicators to assess prognosis in various cardiovascular diseases. In this study, we aimed to investigate the role of hemogram parameters to predict the development of contrast-induced nephropathy (CIN) in patients presenting with non-ST segment elevation myocardial infarction (non-STEMI) and treated with percutaneous coronary intervention (PCI).
Methods: All pateints who underwent PCI with a diagnosis of non-STEMI between 2017 and 2020 in our center were included retrospectively in this study.
Results: A total of 387 patients were included in this retrospective study. Advanced age (p=0.001, β:0.005, OR [95 % CI]: 0.002-0.007), diabetes mellitus (p=0.013, β:0.205, OR [95 % CI]: 0.150-0.260), congestive heart failure (p=0.009, β:0.095, OR [95 % CI]: 0.024-0.166), volume of contrast medium (p=0.008, β:0.241, OR [95 % CI]: 0.184-0.392), MPV (p=0.02, β:0.047, OR [95 % CI]: 0.028-0.065) and NLr (p=0.001, β:0.052, OR [95 % CI]: 0.040-0.063) were found as independent risk factors associated with CIN development according to multivariate logistic regression analysis. A cut off value of 5.5 for NLr was associated with 79.6 % sensitivity and 79.5 % specificity and 9.05 for MPV was associated with 64.1 % sensitivity and 58.7 % specificity in prediction of CIN development.
Conclusions: Hematological parameters, assessed by routine blood count analysis may serve as a promising and useful marker for CIN especially when used in combination with traditional risk factors. MPV and NLr were demonstrated as predictors of CIN development in non-STEMI patients who were treated with PCI in our study.
