Central neural contribution to the perception of chest pain in cardiac syndrome X.

CARDIOVASCULAR MEDICINE Central neural contribution to the perception of chest pain in cardiac syndrome X

Objective: To investigate the central neural contribution to chest pain perception in cardiac syndrome X (angina-like pain, ECG changes during stress, angiographically normal coronary arteriogram). Subjects: Eight syndrome X patients and eight healthy volunteers. Methods: Dobutamine stress using echocardiography to assess myocardial function, and positron emission tomography to measure changes ...

How Effective Is the Use of Metaphor Therapy on Reducing Psychological Symptoms and Pain Discomfort in Patients with Non-Cardiac Chest Pain: A Randomized, Controlled Trial

Introduction: Psychological symptoms of non-cardiac chest pain (NCCP) including perceptual, emotional, and behavioral problems can effect patient perception of chest pain. This study was conducted to determine the effect of metaphor therapy on mitigating depression, anxiety, stress, and pain discomfort in patients with NCCP. Materials and Methods: This randomized, controlled, trial was conducte...

The complex link between brain and heart in cardiac syndrome X.

In cardiac syndrome X, the presence of ischaemic-like ST segment changes during chest pain, in the absence of epicardial coronary stenoses, suggests that myocardial ischaemia caused by coronary microvascular dysfunction is responsible for angina. This view is supported by the documentation of abnormalities in myocardial perfusion on radionuclide studies 3 and abnormal coronary blood flow respon...

Cardiac patients perception about psychological risk factors on chest pain intensity and discomfort

ارتباط بین آنژین صدری و هیپرانسولینیسم در زنان یائسه

Background: Cardiac X Syndrome is the occurrence of angina pectoris in spite of a normal coronary angiogram, probably due to a disorder of the cardiac sensory nervous system (pain perception). The insulin resistance (metabolic X) syndrome is an important determinant of coronary artery disease. There is a dearth of research on the association between insulin resistance and cardiac X syndrome. We...
