Abstract：Objective To analyze the clinical characteristics of acute inferior wall myocardial infarction (IWMI) accompanied by or without right ventricular myocardial infarction (RVMI). Methods The patients (n=256) with IWMI hospitalized within 12 h after disease onset were chosen and divided into group without RVMI (n=167) and group of IWMI accompanied by RVMI (n=89) according to outcomes of CAG. The differences in major risk factors (smoking, hypertension, diabetes, hyperlipidemia and family history of coronary heart disease), clinical symptoms, complications and drug administration were analyzed and compared in two groups. Results There were no differences in major risk factors in two groups. The percentages of hypotension (80.0%vs. 19.8%, P<0.05), distension of jugular vein (50.6%vs. 1.8%) and Kussmaul sign (51.7%vs. 1.2%) were higher in group of IWMI accompanied by RVMI (P<0.01). More positive inotropic drugs (60.7%vs. 16.2%) were needed for keeping blood pressure, and morality (77.9%vs. 0.6%, P<0.05) was higher in group of IWMI accompanied by RVMI. Conclusion IWMI accompanied by RVMI is commonly complicated with right heart failure, which will induce poor prognosis.
