FREQUENCY OF RESOLUTION OF ST-SEGMENT ELEVATION AFTER PRIMARY PERCUTANEOUS CORONARY INTERVENTION IN PATENTS WITH STEMI

Abstract

Objectives: To determine frequency of resolution of ST-segment elevation after primary percutaneous coronary intervention (PPCI) in patents with STEMI.

Materials and Methods:  After approval by the CPSP and the institutional ethics committee, all eligible patients presenting to the Cardiology Department of PGMI/Lady Reading Hospital, Peshawar, were enrolled. Informed consent was obtained, and baseline data (age, gender, BMI, infarct territory) were recorded. Primary PCI was performed by experienced cardiologists following a standard protocol. A repeat ECG was done 30 minutes post-PCI to assess ST-segment resolution. Data were collected using a structured proforma and analyzed with SPSS version 26.

Results: The mean age was 59.77±11.74 years and mean BMI was 26.61 ± 3.15 kg/m². Of the participants, 45.6% were male and 54.4% female. Most were aged 51–60 years, and anteroseptal infarcts were the most common (30.1%). ST-segment resolution occurred in 87.5% of patients. No significant associations were found between resolution and gender, age, infarct territory, or BMI (p > 0.05).

Conclusion: It was concluded that most STEMI patients showed successful ST-segment resolution after primary PCI, with no significant link to age, gender, BMI, or infarct territory. ST-segment resolution remains a key marker of effective reperfusion and should be routinely evaluated. Further large-scale studies are needed to identify additional influencing factors and improve post-PCI care.
