Efficacy of metabolic modulators in ischemic heart disease: an overview

Area of Science:

• Cardiology
• Metabolic Medicine
• Pharmacology

Background:

• Myocardial ischemia, a reduction in heart oxygen supply, causes cardiac dysfunction and remains a leading cause of mortality.
• Current treatments for myocardial ischemia and infarction focus on restoring coronary artery blood flow via fibrinolysis or percutaneous intervention.
• Despite advancements, myocardial ischemia complications persist, highlighting the need for alternative therapeutic strategies.

Purpose of the Study:

• To explore novel therapeutic strategies for myocardial ischemia by focusing on optimizing cardiac energy metabolism.
• To review the role of pharmacological manipulation of metabolic pathways in limiting myocardial damage.
• To discuss conventional and novel metabolic modulators for treating acute and chronic angina.

Main Methods:

• Review of existing literature on metabolic modulators for myocardial ischemia.
• Analysis of evidence for therapeutic interventions targeting cardiac energy metabolism.
• Discussion of pharmacological approaches to alter myocardial substrate utilization.

Main Results:

• Optimizing cardiac energy metabolism presents a promising approach to limit myocardial damage in ischemia.
• Metabolic support strategies aim to enhance glucose metabolism (glycolysis and oxidative phosphorylation) while reducing fatty acid oxidation.
• Evidence for both conventional and emerging metabolic modulators in managing angina is presented.

Conclusions:

• Pharmacological manipulation of cardiac metabolism offers a promising adjunct or alternative therapy for myocardial ischemia.
• Targeting metabolic pathways can mitigate myocardial damage and improve outcomes in patients with ischemic heart disease.
• Further research into metabolic modulators is warranted for effective management of acute and chronic angina.
