Coronary Microvascular Dysfunction, Microvascular Angina, and Treatment Strategies

JACC: Cardiovascular Imaging, 2015
Angina without coronary artery disease (CAD) has substantial morbidity and is present in 10% to 30% of patients undergoing angiography. Coronary microvascular dysfunction (CMD) is present in 50% to 65% of these patients. The optimal treatment of this cohort is undefined.

Breathlessness in microvascular angina

Respiratory Medicine, 1994
In patients with microvascular angina (MA), there is some evidence from studies of plethysmography, that there are widespread microvascular abnormalities. In addition to exertional chest pain, all these patients complain of breathlessness, with no evidence of airways obstruction or resting left ventricular dysfunction.

Comparison of Subfoveal Choroidal Thickness and Retinal Nerve Fiber Layer Thickness in Patients with Coronary Slow Flow Phenomenon and Microvascular Angina: Optical Coherence Tomography based study.

Photodiagnosis and Photodynamic Therapy, 2021
BACKGROUND The aim of this study was to evaluate and compare the subfoveal choroidal thickness (SFCT) and peripapillary retinal nerve fiber layer thickness (pRNFLT) in patients with microvascular angina (MA), coronary slow flow phenomenon (CSFP) and ...

Management of Microvascular Angina Pectoris

American Journal of Cardiovascular Drugs, 2013
Microvascular angina (MVA) is defined as angina pectoris caused by abnormalities of small coronary arteries. In its most typical presentation, MVA is characterized by angina attacks mainly caused by effort, evidence of myocardial ischemia on non-invasive stress tests, but normal coronary arteries at angiography.

Non-invasive assessment of microvascular dysfunction in patients with microvascular angina [PDF]

International Journal of Cardiology, 2017
We aimed to evaluate the microvascular function in patients with microvascular angina (MVA) by assessing 1) the endothelial glycocalyx barrier properties using sublingual microscopy, and 2) the myocardial perfusion reserve using cardiovascular magnetic resonance (CMR) imaging.Sublingual microscopy was performed in 13 MVA patients (angina pectoris, ST ...

Angina microvascular

Actualización en Medicina de Familia
El sistema arterial coronario está compuesto por dos redes vasculares: las arterias coronarias epicárdicas y la microcirculación coronaria. La microcirculación coronaria desempaña un papel crítico en la regulación del flujo sanguíneo coronario. La vasodilatación progresiva de las arteriolas coronarias puede llegar a quintuplicar la circulación ...

Microvascular Angina and Panic Disorder

The International Journal of Psychiatry in Medicine, 1990
Recent cardiac studies have suggested that patients with chest pain and angiographically normal coronaries have “microvascular angina” (MVA). In contrast, prior psychiatric studies have shown that some of these patients have panic disorder (PD). We compared the clinical and psychologic characteristics of fifteen patients with MVA and fifteen patients ...

Recent developments in microvascular angina

Current Atherosclerosis Reports, 2001
Microvascular angina (Syndrome X) is an extremely heterogeneous clinical entity that is the product of genetic, coronary microvascular, metabolic, and clinical factors, which combine together to produce distinct cardiac manifestations and complications. The interactions of these abnormalities remain poorly understood.

Marked Impairment of Endothelium-Dependent Digital Vasodilatations in Patients With Microvascular Angina

Arteriosclerosis, Thrombosis and Vascular Biology, 2020
Supplemental Digital Content is available in the text. Objective: It remains to be elucidated whether and how endothelial functions are impaired in peripheral circulation of patients with coronary functional disorders, such as vasospastic angina (VSA ...

Microvascular Angina: an Update On Diagnosis and Treatment

Future Cardiology, 2015
Many patients with chest pain who are relieved to learn that they have no obstructive stenoses at diagnostic angiography are misclassified as having noncardiac chest pain. Only recently have we developed the conceptual framework and diagnostic tools to understand that ischemic heart disease is not exclusively caused by obstructive coronary artery ...
