ABSTRACT Objective: To evaluate impact of post dilatation performed with NonCompliant Balloon on Angiographical outcome (that is TIMI flow grade) in patients who underwent the primary percutaneous coronary intervention. Study Design: Retrospective crosssectional study. Place and Duration of Study: At Tertiary Cardiac Care Center, Rawalpindi Pakistan from Nov 2020 to Apr 2021. Methodology: The retrospective data of the all the patients with STEMI was assessed via nonprobability consecutive sampling technique and analyzed statistically. The study participants were classified into two categories based on whether they underwent postdilatation or not, i.e., CategoryI: patients who underwent postdilatation with NC balloon and CategoryII: patients who did not undergo postdilatation. The primary study endpoint was postdilatation TIMI flow grade. Continuous study variables were expressed as Mean±SD and categorical variables as frequencies and percentages. Chi square test was applied to find the association between study variables by keeping 95% CI and 5 % margin of error. pvalue <0.05 was considered statistically significant. Results: The study included (n=410) eligible patients in total. Majority were males (n=303; 73.9%), 217 (52.9 %) patients underwent PD procedure. TIMI flow grade did not differ significantly between the two study categories (pvalue > 0.05). Postprocedural success rate was 81.3% for patients with PD. Conclusion: The current study illustrates that PD does not adversely affect the final angiographic outcomes when performed after primary angioplasty. [ABSTRACT FROM AUTHOR]
