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 #x003C;0.05). Subjects with higher LVEF and SBP had fewer MACEs (P-value #x003C;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 #x003C;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.
