Insights
Mitochondria are vital for heart energy. Mitochondrial dysfunction contributes to heart failure, but targeting mitochondrial function shows promise for new heart failure treatments.
Area of Science:
- Cardiology
- Mitochondrial Biology
- Biochemistry
Background:
- The myocardium has high energy demands, utilizing significant adenosine triphosphate (ATP) daily.
- Mitochondria, the cell's powerhouse, are crucial for cardiomyocyte energy production.
- Mitochondrial dysfunction is implicated in various heart diseases and the progression to heart failure.
Purpose of the Study:
- To review key mitochondrial functions in the myocardium.
- To examine the role of mitochondrial dysfunction in cardiac disease and heart failure development.
- To discuss therapeutic strategies targeting mitochondrial function for heart failure.
Main Methods:
- Literature review of bench-to-bedside research.
- Analysis of mitochondrial roles in ischemia/reperfusion injury and calcium homeostasis.
- Examination of evidence for mitochondrial-targeted therapies.
Main Results:
- Mitochondria are central to myocardial energy metabolism and function.
- Dysfunctional mitochondria contribute to maladaptive pathways leading to heart failure.
- Targeting mitochondrial pathways offers potential therapeutic benefits.
Conclusions:
- Mitochondrial health is critical for preventing heart failure.
- Therapeutic strategies aimed at improving mitochondrial function are a promising avenue for heart failure treatment.
Abstract:
The myocardium is among the most energy-consuming tissues in the body, burning from 6 to 30 kg of ATP per day within the mitochondria, the so-called powerhouse of the cardiomyocyte. Although mitochondrial genetic disorders account for a small portion of cardiomyopathies, mitochondrial dysfunction is commonly involved in a broad spectrum of heart diseases, and it has been implicated in the development of heart failure via maladaptive circuits producing and perpetuating mitochondrial stress and energy starvation. In this bench-to-bedside review, we aimed to (i) describe the key functions of the mitochondria within the myocardium, including their role in ischemia/reperfusion injury and intracellular calcium homeostasis; (ii) examine the contribution of mitochondrial dysfunction to multiple cardiac disease phenotypes and their transition to heart failure; and (iii) discuss the rationale and current evidence for targeting mitochondrial function for the treatment of heart failure, including via sodium-glucose cotransporter 2 inhibitors.

Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
