The relationship between H2FPEF score and contrast induced nephropathy in patients with ST elevation myocardial infarction

Introduction: In the present study, we aimed to investigate the relationship between H2FPEF score and Contrast Induced Nephropathy (CIN) in patients with myocardial infarction with ST segment elevation (STEMI).

Methods: A total of 355 patients who had been diagnosed with ST elevation-myocardial infarction and undergone primary coronary angioplasty were retrospectively included in the study. The patients were divided into two groups according to the presence of CIN and these groups were compared in terms of baseline characteristics and laboratory findings. The H2FPEF score was calculated for each patient on admission and later compared between the groups.

Results: The distribution of the study population was as following: 63 (17.7%) CIN (+) and 292 (82.2%) CIN (-). In CIN (+) group, the mean H2FPEF Score (2.00±1.60 vs 1.25±1.26, P<0.001) was significantly higher than the CIN (-) group. H2FPEF Score (OR: 1.25, 95%CI: 1.01-1.55), and mean age (OR: 1.03, 95%CI: 1.00-1.06) were found to be independently associated with CIN development.

Conclusion: H2FPEF score is an independent predictor of CIN development in patients with acute STEMI. It is easily calculated and and may be used to estimate the CIN in STEMI patients.
