The aim of this study is to measure how different people respond to mental stress. The investigators will measure if there are differences in cardiovascular responses to mental stress among different groups of subjects. In one part of the study the investigators will compare the cardiovascular responses to mental stress between healthy women and healthy men. In another part of the study, the investigators will compare the cardiovascular responses to mental stress between women with apical ballooning syndrome and healthy post-menopausal women. The investigators hypothesize that healthy men will have an increased vascular response to and decreased endothelial function in response to to mental stress, compared to health women. Furthermore, the investigators hypothesize that women with apical ballooning syndrome will have an increased vascular response to and decreased endothelial function in response to mental stress.

Coronary Endothelial Dysfunction

Peripheral and coronary endothelial dysfunction in type 2 diabetic patients may be influenced by therapeutics. Using Radial flow monitoring and myocardial perfusion magnetic resonance imag...
The purpose of this study is to examine the hypothesis that the presence of complex coronary lesions is associated with endothelial dysfunction, the investigators investigated whether fing...
Coronary Artery Disease (CAD) is common in Mexico, while morbidity and mortality is high. Drug therapy can relieve angina pain and stabilize plaque, but it is not able to re-flow a coronar...
The aim of this study is to show the frequency of endothelial dysfunction in patients suffering from ectatic coronary arteries as compared to those who have normal coronary arteries. Shoul...
The aim of this prospective study is to investigate the prevalence of endothelial dysfunction in subjects with family history of premature coronary heart disease. At the same time, the eff...
The role of serum uric acid in coronary artery disease has been extensively investigated. It was suggested that serum uric acid level (SUA) is an independent predictor of endothelial dysfunction and r...
Coronary artery disease (CAD) is now an important cause of premature death in people with HIV but the causes of accelerated CAD are poorly understood. Epicardial adipose tissue (EAT) is metabolically-...
To date, clinical evidence of microvascular dysfunction in patients with heart failure (HF) with preserved ejection fraction (HFpEF) has been limited. We aimed to investigate the prevalence of coronar...
The xanthine oxidase (XO) system is a significant source of vascular oxidative stress, which is believed to impair endothelial function, an important contributor to atherosclerotic disease. We tested ...
Diabetes is a complex progressive disease characterised by chronic hyperglycaemia and dyslipidaemia associated with endothelial dysfunction. Oxidised LDL (Ox-LDL) is elevated in diabetes and may contr...
Abnormal balloon- or sac-like dilatation in the wall of CORONARY VESSELS. Most coronary aneurysms are due to CORONARY ATHEROSCLEROSIS, and the rest are due to inflammatory diseases, such as KAWASAKI DISEASE.
Malformations of CORONARY VESSELS, either arteries or veins. Included are anomalous origins of coronary arteries; ARTERIOVENOUS FISTULA; CORONARY ANEURYSM; MYOCARDIAL BRIDGING; and others.
Complete blockage of blood flow through one of the CORONARY ARTERIES, usually from CORONARY ATHEROSCLEROSIS.
Direct myocardial revascularization in which the internal mammary artery is anastomosed to the right coronary artery, circumflex artery, or anterior descending coronary artery. The internal mammary artery is the most frequent choice, especially for a single graft, for coronary artery bypass surgery.
Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
