Management of ST-segment elevation myocardial infarction in comparison to European society of cardiology guidelines in Alexandria University Hospitals, Egypt.

backgroundFor patients with ST-elevation myocardial infarction (STEMI), early reperfusion with primary percutaneous coronary intervention (PPCI) or thrombolytic treatment is essential to prevent major adverse cardiac events. The aim of the study is to compare the current status of managing STEMI patients at **** with European Society of Cardiology guidelines recommendations. Prospective cohort of all patients presenting with ST-elevation myocardial infarction (STEMI) between March 2020 and February 2021 in Alexandria University hospitals. Reporting patterns, causes of delay, and reperfusion status for all STEMI patients were noted. MACE: (Mortality, Re-infarction, Stroke, or Heart failure) was reported and compared among different management strategies.

resultsThe study was conducted over one year on 436 patients, 280 (64.2%) of them underwent PPCI, 32 (7.3%) received thrombolysis, and 124 (28.5%) had a conservative strategy. Patients' mean age was 55.2 years, 72.2% were smokers and 80.9% were men. Family history was positive in 14.2% of patients, 33.5% had diabetes, 7.3% had renal impairment, and 41.5% had hypertension. The median pre-hospital waiting time was 360 min; the mean pre-hospital waiting time was 629.0 ± 796.7 min. The median Emergency Room waiting time was 48.24 ± 89.30 min. The median time from CCU admission to wire crossing was 40.0 min with a mean value 53.86 ± 49.0 min. The mean ischemia duration was 408 min, while the total ischemic time was 372 min. All patients who presented within 12 h received reperfusion therapy either a PPCI or thrombolysis at a rate of 71.5%, with 35.0% of those patients achieving prompt reperfusion in accordance with ESC guidelines. The PPCI group mortality rate was 2.9%, in comparison to 12.9% in the conservative group, which was statistically significant (P < 0.001). Overall in-hospital mortality was 5.5%, and total MACE was 27.3%. A statistically significant difference was observed between the three management groups as regards MACE rate, being 15%, 28.1%, and 54.8% in PPCI, thrombolysis, and conservative groups, respectively.

conclusionsDespite financial and technical constraints, appropriate, timely reperfusion was near to achieving the ESC guidelines for the management of STEMI. The most common reperfusion strategy was PPCI, with an in-hospital death rate of less than 5% in the PPCI group. There was a concern about the increase in the total ischemia time due to some financial and technical constraints.
