Insights

Intracoronary nicorandil reduced reperfusion complications like no-reflow and ventricular arrhythmia during percutaneous coronary intervention (PCI) for acute myocardial infarction (MI), improving myocardial perfusion.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Pharmacology

Background:

  • Intravenous nicorandil aids cardiac function post-percutaneous coronary intervention (PCI) in acute myocardial infarction (MI).
  • Limited data exists on intracoronary nicorandil's efficacy in acute MI patients undergoing PCI.

Purpose of the Study:

  • To evaluate the effectiveness of intracoronary nicorandil in reducing reperfusion injury during PCI for acute ST-segment elevation MI.

Main Methods:

  • A randomized study involved 73 acute ST-segment elevation MI patients undergoing PCI.
  • Patients were assigned to receive either intracoronary nicorandil (Nicorandil Group, n=37) or a control (Control Group, n=36).
  • Composite endpoints included ventricular arrhythmia, no-reflow, and slow flow, with Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow assessed.

Main Results:

  • The Nicorandil Group showed a significant reduction in the composite endpoint (p=0.037).
  • Post-PCI TIMI grade 3 flow was significantly higher in the Nicorandil Group (p=0.019).
  • Major adverse cardiac events were comparable between groups during hospitalization and at 30 days.

Conclusions:

  • Intracoronary nicorandil administration effectively reduces no-reflow, slow reflow, and reperfusion arrhythmias in acute MI patients undergoing PCI.
  • It improves myocardial perfusion and TIMI flow, leading to better clinical outcomes.
  • Intracoronary nicorandil is a promising therapeutic option for mitigating reperfusion injury in acute MI.

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...

Antianginal Drugs: Nitrates and β-Blockers

In cardiovascular health, antianginal drugs combat angina pectoris — a condition marked by chest pain owing to diminished blood flow to the heart.
Organic nitrates,  such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow. Administered...
