Clinical features and outcomes of patients with stable or unstable chest pain and no-obstructive coronary artery disease

Frontiers in Cardiovascular Medicine, 2022
BackgroundCoronary microvascular dysfunction can be responsible for both stable angina and acute coronary syndrome (ACS). There are scarce data, however, about comparisons of clinical characteristics and outcomes of these 2 groups of patients.Materials ...

The relationships between acetylcholine-induced chest pain, objective measures of coronary vascular function and symptom status

Frontiers in Cardiovascular Medicine, 2023
BackgroundAcetylcholine-induced chest pain is routinely measured during the assessment of microvascular function.AimsThe aim was to determine the relationships between acetylcholine-induced chest pain and both symptom burden and objective measures of ...

Obesity, inflammation and brachial artery flow-mediated dilatation: Therapeutic targets in patients with microvascular angina (Cardiac Syndrome X)

, 2012
Background The pathophysiology of microvascular angina (cardiac syndrome X, CSX), (effort-induced angina, a positive response to exercise stress testing and angiographically normal coronary arteries) has not been fully elucidated.

Whole blood viscosity in microvascular angina and coronary artery disease: Significance and utility

Revista Portuguesa de Cardiologia, 2020
Introduction and Objectives: Whole blood viscosity (WBV) is the intrinsic resistance of blood flow in vessels, and when elevated induces endothelial shear stress and endothelial inflammation and can accelerate the atherosclerotic process. This study aims

Paradoxical coronary vasospasm and transient apical ballooning in a post-menopausal woman: An imaging case report of an unusual INOCA presentation

American Heart Journal Plus, 2022
Ischemia with non-obstructive coronary artery disease (INOCA), a common cause of angina, can occur due to coronary vasospasm, microvascular dysfunction, endothelial dysfunction, atherosclerosis or a combination of these mechanisms.

Management options for coronary microvascular dysfunction: Present status and future perspectives

Journal of Clinical and Preventive Cardiology, 2016
Coronary micro vessels are not visible on coronary angiography. These include prearterioles, arterioles, and capillaries. Significant number of patients of angina have coronary microvascular dysfunction alone or in combination with stenosis and/or spasm ...

Fluoroscopic methods of assessment of coronary microvascular dysfunction – a review of literature [PDF]

Българска кардиология
A large proportion of patients with angina and evidence of myocardial ischemia do not have obstructive coronary disease. One of the main mechanisms of ischemia/angina with non-obstructive coronary arteries is coronary microvascular dysfunction, which is ...

The invasive investigation of INOCA in the coronary catheterization lab

American Heart Journal Plus
Over half of all patients with angina have no angiographically demonstratable obstructive coronary disease, with a significant proportion of these patients having undiagnosed microvascular dysfunction and/or vasospastic angina.

Different definition of microvascular angina [PDF]

European Journal of Clinical Investigation, 2015
AbstractWe sometimes encounter patients with microvascular angina (MVA), a disease characterized by anginal pain without abnormal coronary arteriographic findings or coronary spasm. More than 40 years have passed since MVA was first confirmed. The terms ‘syndrome X’, ‘cardiac syndrome X’ and ‘microvascular dysfunction’ have also been used to describe ...

Takotsubo cardiomyopathy in two patients with microvascular angina

, 2015
We present two cases in which takotsubo cardiomyopathy (TC) developed immediately after a diagnosis of microvascular angina had been established. One patient who had been diagnosed as having endothelium-dependent microvascular angina (microvascular spasm)
