[Angina pectoris with normal coronary arteries]
1Hospital Distrital de Torres Vedras.
Insights
Angina with normal coronary angiograms, also known as INOCA, is being studied. Its cause may involve small vessel dysfunction and endothelial issues, not epicardial coronary artery disease.
Area of Science:
- Cardiology
- Vascular Biology
- Internal Medicine
Context:
- Investigating angina pectoris in patients presenting with normal coronary angiograms, a condition recognized since 1967.
- Exploring the etiology of chest pain when epicardial coronary artery disease is absent.
- Focusing on the role of small coronary vessels and endothelial function in this syndrome.
Purpose:
- To review the latest research on the pathophysiology of angina with normal coronary angiograms.
- To present current understanding of the clinical presentation of this condition.
- To summarize contemporary management strategies for patients with angina and normal coronary arteries.
Summary:
- This review synthesizes recent findings on angina pectoris in patients with unobstructed epicardial coronary arteries.
- It highlights the potential roles of small coronary artery dysfunction and endothelial abnormalities in the syndrome's development.
- The paper covers the pathophysiology, clinical features, and treatment approaches for this challenging condition.
Impact:
- Enhances understanding of ischemic chest pain in the absence of obstructive coronary artery disease.
- Provides clinicians with updated information for diagnosing and managing patients with angina and normal coronary angiograms.
- Contributes to the ongoing research into the complex mechanisms underlying microvascular dysfunction and endothelial impairment.
Abstract:
The occurrence of angina pectoris in patients with normal coronary angiograms is a subject of investigation since its first description as an entity in 1967. Its etiology remains unknown but, in the absence of disease of the epicardial coronary arteries, dysfunction of the small, most distal vessels and the endothelium appear to be incriminated. In this review, the most recent knowledge and understanding of the pathophysiology, clinical presentation and management of this syndrome is presented.
