Precision Medicine: Therapeutically Targeting Mitochondrial Alterations in Heart Failure

Area of Science:

• Cardiovascular Disease Research
• Mitochondrial Biology
• Metabolic Disorders

Background:

• Heart failure (HF) affects over 64 million adults globally, significantly contributing to cardiovascular disease burden.
• Mitochondrial dysfunction, oxidative stress, and impaired myocardial energetics are key drivers of HF progression and mortality.
• Current HF therapies target neurohormonal pathways but do not directly address mitochondrial defects.

Purpose of the Study:

• To review metabolic derangements driving HF progression, focusing on mitochondrial roles.
• To identify knowledge gaps and highlight translational strategies for targeting mitochondrial pathways in HF.
• To discuss challenges and recent developments in novel mitochondrial-targeted therapies for HF.

Main Methods:

• Literature review summarizing metabolic pathways and mitochondrial function in HF.
• Analysis of current therapeutic approaches and their limitations regarding mitochondrial targets.
• Exploration of emerging mitochondrial-targeted strategies and their translational potential.

Main Results:

• Mitochondrial respiratory alterations and oxidative stress are central to HF pathogenesis.
• Conventional HF therapies offer limited direct benefits for mitochondrial dysfunction.
• Targeting mitochondria presents a promising avenue for novel HF treatments.

Conclusions:

• Mitochondrial-targeted therapies hold significant potential for advancing HF treatment beyond current standards.
• Addressing metabolic derangements and mitochondrial dysfunction is crucial for effective HF management.
• Further research and development are needed to overcome challenges in deploying novel mitochondrial therapies for HF.
