Pulse pressure and inferior wall ST‑segment elevation myocardial infarction: investigating mortality, hospital major cardiovascular events, and long‑term prognosis

Abstract

Inferior Wall ST‑Segment Elevation Myocardial Infarction (INF STEMI) is a severe condition with high mortality. Rapid treatment with Primary Percutaneous Coronary Intervention (PPCI) is preferred. Pulse Pressure(PP) is a known risk factor for both cardiovascular disease and may be a valuable predictor of outcomes in these patients. The study aims to evaluate the relationship between PP and long‑term prognosis, mortality, and major cardiovascular events after inferior STEMI in cases who underwent PPCI. This cross‑sectional study included subjects with a confirmed diagnosis of inferior STEMI who underwent PPCI. Patient data were gathered from hospital records and analyzed for the relationship between PP and MACE during hospitalization and one‑year follow‑up. Statistical analysis was performed using SPSS. This cross‑sectional study of 320 cases found that DM, DBP, and Cr patients had a higher incidence of MACEs (P‑value <0.05). Subjects with higher LVEF and SBP had fewer MACEs (P‑value <0.05). Cases with a PP of ≤50 had a higher mortality and heart failure incidence during hospitalization than those with a PP >50(P‑value <0.05). However, the two groups had no significant difference in one‑year MACE rates. The study found that increasing DBP, Cr, and DM and decreasing LVEF and SBP impacted MACE incidence. PP ≤50 had more heart failure incidence and mortality during hospitalization in patients with inferior STEMI.
