Coronary Spasm: Ethnic and Sex Differences [PDF]

European Cardiology Review, 2023
Coronary spasm (CS), which may occur at the epicardial (focal or diffuse spasm) and/or microvascular (microvascular spasm) level, is a well-established cause of myocardial ischaemia, in particular in patients with anginal chest pain despite unobstructed ...

Spontaneous multi-focal coronary artery spasm: a case report [PDF]

Journal of Cardiovascular and Thoracic Research, 2016
Spontaneous coronary artery vasospasm is one of the important causes of acute chest pain syndromes. The diagnosis of diffuse multifocal spasm can be quite challenging and it could be easily mistaken for diffuse coronary artery disease.

Coronary Artery Spasm [PDF]

Angiology, 1980
Coronary artery spasm is a transient reduction in lumen diameter of an epicardial coronary artery of sufficient degree to produce objective evidence of myocardial ischemia in the absence of any significant increase in heart rate or blood pressure. In this article are summarized pathophysiological observations, the coronary angiographic anatomy of ...

Layered Plaque in Organic Lesions in Patients With Coronary Artery Spasm

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2022
Background Coronary artery spasm plays a vital role in the pathogenesis of coronary plaques. We sought to investigate the plaque characteristics of co‐existing organic lesions in patients with coronary artery spasm in comparison to those without coronary

Complete Blood Count-Derived Indices as Prognostic Factors of 5-Year Outcomes in Patients With Confirmed Coronary Microvascular Spasm

Frontiers in Cardiovascular Medicine, 2022
BackgroundCoronary microcirculatory dysfunction is a meaningful factor in the development of ischemic heart disease. We investigated the relationship between coronary microvascular spasm and complete blood count indices.MethodsBetween 2010 and 2013, we ...

Prevention of epicardial coronary artery spasm with intracoronary nitroglycerine during acetylcholine testing in a female patient with resting angina—implications for optimal pharmacological management

Clinical Case Reports, 2022
We here present the case of a 55‐year old woman who presented with recurrent angina at rest followed by presyncopal attacks and nausea to our clinic. Her only cardiovascular risk factor was arterial hypertension. High‐sensitive troponin T was 3 pg/ml (n

Clinical Characteristics and Prognosis of Patients with Vasospastic Angina Subjected to the Spasm Provocation Test and the Unavoidable Use of Nitroglycerin

Journal of Cardiovascular Development and Disease, 2023
Background: Multi-vessel spasm (MVS) has a prognostic impact in patients with vasospastic angina (VSA). Thus, the presence of coronary spasm in both the left coronary artery (LCA) and right coronary artery (RCA) should be assessed through the spasm ...
