OR48. Major risk factors for in-hospital mortality events of acute coronary syndrome patients in the rural hospital setting

This study was performed to find major risk factors for all-cause in-hospital mortality events of acute coronary syndrome (ACS) patients in the rural hospital setting, where diagnostic and therapeutic resources were limited.

We enrolled 57 ACS patient data that were admitted from January to December 2020 from medical records. Patient baseline data, clinical characteristics, risk factors and their association with in-hospital all-cause mortality events were analyzed. The median age of all patients was 58.0 ± 10.63 years, with predominantly male patients (68.4%). There were 35.1% ST-elevation acute coronary syndrome (STEACS) and 64.9% non-ST-elevation acute coronary syndrome (NSTEACS) cases, with 17.5% all-cause in-hospital death cases. All of the dead patients were male and had active smoking behaviour. The other most prevalent risk factors were history of chronic heart failure (60.0%), ST-segment deviation (50%) and atrioventricular block findings on electrocardiogram (50%). Bivariate Fischer’s exact test showed significant correlation in male patients (OR: 0.74; 95% CI: 0.62 to 0.89; p: 0.022), history of chronic heart failure (OR: 0.16; 95% CI: 0.04 to 0.68; p: 0.015), and active smoking behaviour (OR: 0.72; 95% CI: 0.59 to 0.84; p: 0.009) with all-cause in-hospital mortality events.

Active smoking behaviour, history of chronic heart failure and male patients were found to be major risk factors for all-cause in-hospital mortality events in acute coronary syndrome patients in the rural hospital setting.
