Targeted Therapies for Microvascular Disease.

Area of Science:

• Cardiology
• Vascular Biology
• Internal Medicine

Background:

• Coronary microvascular dysfunction (CMD) causes myocardial ischemia without obstructive coronary artery disease, hindering adequate oxygen supply.
• Current diagnostic and therapeutic strategies for CMD are limited by insufficient mechanistic research and targeted treatments.
• CMD affects the heart's ability to meet oxygen demands, leading to significant clinical challenges.

Purpose of the Study:

• To review current evidence on managing coronary microvascular dysfunction.
• To explore the role of invasive assessment in stratifying antianginal therapies for CMD.
• To provide an evidence-based appraisal of treatment strategies for CMD.

Main Methods:

• Literature review of recent evidence on CMD management.
• Appraisal of diagnostic approaches for coronary microcirculation assessment.
• Evaluation of therapeutic interventions including risk factor modification, antianginal therapy, and atherosclerosis treatment.

Main Results:

• Invasive assessment aids in stratifying antianginal therapies for improved patient outcomes in CMD.
• Management strategies involve addressing cardiovascular risks, optimizing antianginal treatments, and managing atherosclerosis.
• Evidence supports tailored therapeutic approaches based on the specific diagnosis of coronary microcirculation impairment.

Conclusions:

• Stratified antianginal therapy based on invasive CMD assessment can improve patient outcomes.
• Comprehensive management of CMD requires addressing cardiovascular risk factors and atherosclerosis.
• Further research into CMD mechanisms is crucial for developing more targeted therapies.
