Short-term outcomes of tirofiban use in primary percutaneous coronary intervention for acute ST-segment elevation myocardial infarction (STEMI)

Abstract

Introduction: When patients suffering from acute ST-elevation myocardial infarction (STEMI) undergo for percutaneous coronary intervention, tirofiban is mostly prescribed. Objective: In this study, patients undergoing for primary percutaneous coronary intervention for ST-segment elevation myocardial infarction were evaluated to determine the impact of a high bolus dose (HBD) of tirofiban on clinical outcomes. Methods: This study included 272 acute STEMI patients aged less than 79 years, admitted to the Hayatabad Medical Complex hospital, Peshawar from April 2021 to February 2022. According to the random number table, these patients were divided into four groups: the control group (n= 65), low-dose group (n=69), medium-dose group (n=71) and high-dose group (n=67). Results: After percutaneous coronary intervention, the high-dose group experienced higher rates of corrected TIMI frame count (CTFC), Thrombolysis In Myocardial Infarction (TIMI) grade 3, and total frequency of ST-segment resolution greater than 50% than the other 3 groups while compared to the low- dose group as well as control group, the CTFC were greater in the medium dose group. Furthermore, the LVEF of the medium-dose group was much better than that of the low-dose group. Compared to other groups, the left ventricular end-diastolic and end-systolic dimensions of the high-dose group remained suggestively elevated.
