Abstract

ABSTRACT

Introduction: It is debatable how SPD (stent post-dilatation) work during PPCI (primary percutaneous

intervention). It is up to the operator to decide when to execute stent after dilatation because there are

currently no definitive rules or general agreement on the subject. Objective: To assess the results of PPCI

(primary percutaneous coronary intervention) in participants having ST segment elevation myocardial

infarction with as well as without post-dilatation. Methodology: This retrospective analysis research was

performed in Hayatabad medical complex, Peshawar, Pakistan after the approval from the institutional

and ethical review board. The study included 180 patients, both sexes, ages 18 to 70 years, who received

primary percutaneous coronary intervention due to STEMI. The patients' various characteristics, such as

DM, HTN (hypertension), CKD (chronic kidney disease), BMI, smoking history, the location of the MI,

blood pressure, the type of artery, and the TIMI flow before and after the procedure, were recorded in an

excel sheet. Results: Regarding the culprit artery, there wasn't a scientifically significant distinction between

the two categories; group 1's left anterior descending artery (LAD) was observed in 50 (55.5%) cases & in

group 2 in 49(54.4%) cases. Right coronary artery (RCA) in group 1 in 31(34.4%) and 27(30%) in group

2. Left circumflex artery (LCX) in group 1 was noted in 17(18.9%) and 19(21.1%) in group 2. The use of

thrombus aspiration catheters was greater in group 2 than in group 1, with 24 (26.7%) compared to 15

(16.7%). GP IIb/IIIa inhibitors were given to 20 (22.2%) individuals in group 2 compared to 18 (20%)

patients in group 1. Patients in groups 1 and 2 had substantially larger pre-stenting balloon dilatation, 44

(48.9%) and 11 (12.2%), respectively. In both groups, every patient got DES (drug-eluting stents).

Conclusion: In patients with STEMI, selective postdilation enhanced some angiographic and clinical

outcomes, and it could not be discouraged from being used in the primary percutaneous coronary

intervention
