Effect of Post Dilatation on TIMI Flow in Patients Undergoing Primary Percutaneous Coronary Intervention

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