Preliminary quantitative myocardial perfusion in response to cold pressor test in normals
نویسندگان
چکیده
Background Echo and nuclear studies have shown that coronary flow changes with the cold pressor test (CPT). CPT has been used to measure coronary flow response because it provides an endothelium-dependent coronary vasodilation that is sensitive for detecting early changes in coronary endothelial function. There was also a study showed myocardial perfusion increases during CPT with first pass perfusion imaging [1]. We studied the regional myocardial perfusion values in normal volunteers under stress (CPT), at rest, and myocardial flow reserve (MFR).

AIMS To investigate whether and how cold pressor test (CPT) could affect myocardial perfusion and left ventricular (LV) function in patients with previous LV ballooning syndrome (LVBS). METHODS AND RESULTS Cold pressor test (3 min hand immersion in ice-water) was performed in 17 women with previous LVBS and in 7 age- and risk factor-matched women with chest pain and normal coronary arteries. ...

Purpose Alterations in myocardial perfusion are crucial for coronary artery disease (CAD). In nuclear medicine a risk assessment is established that can reveal endothelial dysfunction which is the first step towards CAD: the cold pressor test (CPT) [1, 2]. Nuclear medicine provides the opportunity to quantify myocardial blood flow but suffers from two main drawbacks: limited spatial resolution ...

Objective: To test the hypothesis that scintigraphic regional myocardial perfusion defects during exercise in patients with normal coronary angiography may be related to abnormal endothelium dependent vasoreactivity of the corresponding myocardial territory in response to cold pressor testing. Methods: 38 patients were classified into two groups according to the presence or absence of exercise ...
متن کاملImpaired Coronary Blood Flow Regulation in Patients With Early Atherosclerosis
Background. The vascular endothelium is capable of regulating tissue perfusion by the release of endothelium-derived relaxing factor to modulate vasomotor tone of the resistance vasculature. Methods and Results. To test whether atherosclerosis is associated with a functional abnormality of endothelium-mediated microvascular relaxation affecting coronary blood flow regulation, we compared corona...
متن کاملImpairment of coronary microvascular dilation in response to cold pressor--induced sympathetic stimulation in type 2 diabetic patients with abnormal stress thallium imaging.
Coronary microcirculation dysfunction may be associated with myocardial perfusion defects on thallium imaging in diabetic patients without coronary artery stenosis. Microvascular coronary adaptation to increased myocardial oxygen demand in response to sympathetic stimulation evoked by the cold pressor test was examined in 22 type 2 diabetic patients with thallium imaging defects and in 15 contr...
