Total Ischemic Time on In-Hospital Complication Predictor in ST-Elevation Myocardial Infarction (STEMI) Patients With...

Aim The purpose of this study was to examine the impact of total ischemic time (TIT) on in-hospital complications in acute ST-elevation myocardial infarction (STEMI) patients with renal dysfunction (RD). Methods The study included a total of 116 patients. All patients underwent percutaneous coronary intervention. Glomerular filtration rate (GFR) was < 60 ml/min/1.73 m² in all patients. The patients were split into two groups based on the TIT value. All eligible patients were assigned to two groups according to TIT: Group 1 comprised 54 patients with ≤ 6-hour TIT and Group 2 consisted of 62 patients with > 6-hour TIT. The groups' other characteristics were similar. The composite rate of pulmonary edema and cardiogenic shock were compared between groups. Results The mean TIT in Group 1 was 4.37 ± 1.35 and in Group 2 was 9.03 ± 1.59 (p < 0.0001). The incidence of pulmonary edema or cardiogenic shock was higher in Group 2 than in Group 1: 16.1% and 3.7%, respectively (p = 0.034). Conclusion STEMI patients with RD and higher TIT were more likely to develop pulmonary edema and cardiogenic shock.
