ABSTRACT

Objective: To determine the frequency of primary percutaneous coronary intervention (PPCI) use as reperfusion strategy in patients with STEMI and in-hospital outcomes.

Study Design: Cross-sectional study

Place and Duration of Study: Department of Cardiology, National Institute of Cardiovascular Disease, Karachi from 1st January 2020 to 30th June 2020.

Methodology: Three hundred and seventy-one patients were enrolled. Patients with unstable angina or non-ST-elevation myocardial infarction (NSTEMI) were excluded. Data regarding demographics, clinical features, and duration of signs& symptoms, the treatment was given was recorded.

Results: There were 300 (80.86%) males and 71 (19.34%) females with a mean age were 51.42±6.75 years and the mean duration of symptoms was 97.20±76.92 minutes. More than half of all patients (53.1%) belonged to urban areas; the other one-third (32.3%) were from peri-urban areas while those from rural areas were only 14.6%. One-third (35.6%) were smokers, one quarter (24.8%) were obese, the other 12.7% had diabetes mellitus, 18.3% had hypertension while 8.6% of patients had a positive family history of CAD.

Conclusion: The survival rate among patients treated with primary PCI is more than those treated with pharmacological therapy alone. Some influencing factors are age, gender, duration of reaching the tertiary care hospital, and residence of patients.
