Frequency of non-st segment elevation myocardial infarction (NSTEMI) in acute coronary syndrome among patients presenting with the chest pain in emergency department of tertiary care hospital.

Objective: To determine the frequency of NSTEMI (non- st elevation myocardial infarction) in acute coronary syndrome patients presenting with the chest pain in emergency department of tertiary care hospital. Study Design: Cross Sectional study. Setting: Jinnah Post graduate Medical College Hospital Karachi. Period: June 20, 2023. Methods: Enrolling 112 consecutive volunteers was carried out Interview questions focused on the participants' smoking, blood pressure, diabetes, and type of chest pain. Whether or not the participants had ACS, their diagnosis was documented. NSTEMI frequency was computed. Results: We have 112 patients enrolled with mean age was 52.73±14.24 years. Sixty five (58%) were male while forty seven (41.9 %) were females. out of 112 patients 45 (40.1%) were hypertensive, 32(28.5%) were diabetes and 29 (25.8%) were smoker. Among the participants 21 (18.7%) had NSTEMI and showed positive correlation with age, gender, nature of chest pain, hypertension and smoking. Conclusion: Among the individuals, one of the most frequent causes of chest pain was acute coronary syndrome.
