Background: Inferior wall ST-segment elevation myocardial infarction (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.
Objective: 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.
Methods: 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.
Result: 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.
Conclusion: 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.
