Condition(s) targeted: Acute Myocardial Infarction; Percutaneous Coronary Intervention
Intervention: Diltiazem (Drug); Verapamil (Drug); Nitroglycerin (Drug)
Phase: Phase 4
Status: Completed

Summary
The purpose of this study is to evaluate the efficacy of three different vasodilators
including diltiazem, verapamil and nitroglycerin for reversal of no-reflow/slow-flow during
direct percutaneous coronary intervention for acute myocardial infarction.
Clinical Details
Official title: Reversal of No-reflow/Slow-flow During Percutaneous Coronary Intervention in Patients With Acute Myocardial Infarction--a Prospective Randomized Study Comparing Intracoronary Infusion of Diltiazem, Verapamil and Nitroglycerin
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: Vessel flow using TIMI flow grade and TIMI frame count
Secondary outcome: major adverse cardiovascular events (MACE)Left ventricular ejection fraction (LVEF) through echocardiography NT-proBNP levels incidence of complete ST-segment resolution peak troponin T level
Detailed description:
No-reflow/slow-flow is a frequent observation during direct PCI for AMI and associated with
a poor clinical outcome. The present pharmacological management involves the use of
different vasodilators including nitrates, verapamil, adenosine and nicorandil. But no
randomized trial has been conducted to assess any of these agents, or to determine the
appropriate dosage. This prospective randomized study aimed to confirm favorable effects of
diltiazem on no-reflow/slow-flow during direct PCI for AMI compared with verapamil and
nitroglycerin.
