Impaired endothelium-dependent relaxation to aggregating platelets and related vasoactive substances in porcine coronary arteries in hypercholesterolemia and atherosclerosis.
Vasoconstrictor responses are augmented in porcine coronary arteries in hypercholesterolemia and atherosclerosis, leading to an occurrence of coronary vasospasm in the latter condition. The role of the endothelium in the vascular hyperreactivity in hypercholesterolemic and atherosclerotic coronary arteries was examined, particularly in response to aggregating and related vasoactive substances. ...
متن کاملEndothelin. Key to coronary vasospasm?
In 1959, Prinzmetal and colleagues described a new form of chest pain that developed at rest and very often occurred in the early morning hours.12 The pain was associated with ST segment elevations in the electrocardiogram and relieved by nitroglycerin. They named the syndrome "variant angina" and suggested that it was caused by a spasm of a major epicardial coronary artery. Subsequently, coron...
متن کاملTwo-dimensional myocardial deformation in coronary vasospasm-related Takotsubo cardiomyopathy
RATIONALE Although transient reduction in the left ventricular ejection fraction is characteristic of Takotsubo cardiomyopathy, little is known about the time-course changes of myocardial deformation in coronary vasospasm-related Takotsubo cardiomyopathy. PATIENT CONCERNS We retrospectively analyzed the time-course changes in left ventricle, right ventricle, and left atrium strain values in a...
متن کاملIntrarenal transport and vasoactive substances in hypertension.
Blood pressure is influenced by several vasoactive factors that also regulate nephron transport. An imbalance in regulation of salt reabsorption by the nephron contributes to hypertension. In the spontaneously hypertensive rat (SHR), the responses to dopamine and angiotensin II in the proximal nephron are diminished and enhanced, respectively. This partially explains why the proximal tubule of ...
متن کاملThe interaction of vasoactive substances during exercise modulates platelet aggregation in hypertension and coronary artery disease
BACKGROUND Acute vigorous exercise, associated with increased release of plasma catecholamines, transiently increases the risk of primary cardiac arrest. We tested the effect of acute submaximal exercise on vasoactive substances and their combined result on platelet function. METHODS Healthy volunteers, hypertensive patients and patients with coronary artery disease (CAD) performed a modified...
