Coronary microvascular dysfunction

Area of Science:

• Cardiology
• Vascular Biology
• Internal Medicine

Background:

• Coronary microvascular dysfunction (CMVD) affects a significant patient population.
• Patients often experience angina symptoms, leading to a reduced quality of life despite a good overall prognosis.
• Understanding CMVD is crucial for improving patient outcomes.

Purpose of the Study:

• To summarize clinical presentations of CMVD, including stable and unstable microvascular angina.
• To discuss risk factors, pathogenic hypotheses, diagnosis, and treatment of CMVD.
• To analyze less understood microvascular alterations, prognosis, and quality of life impacts.

Main Methods:

• Literature review and synthesis of current knowledge on CMVD.
• Discussion of clinical presentations, risk factors, and pathophysiology.
• Analysis of diagnostic approaches and therapeutic strategies.

Main Results:

• CMVD presents with various clinical pictures, notably stable and unstable microvascular angina.
• Key risk factors and current pathogenic hypotheses are outlined.
• Diagnostic criteria and treatment options are reviewed, including novel insights.

Conclusions:

• CMVD significantly impacts patient quality of life through persistent angina.
• Further research into microvascular alterations like slow flow and no-reflow is needed.
• Comprehensive management strategies are essential for improving outcomes in CMVD patients.
