Sodium Nitroglycerin Induces Cerebrovascular Vasodilation in Patients with Ischemic Heart Disease

Aging patients with ischemic heart disease (IHD) have impaired cerebrovascular vasodilation in response to hypercapnia, but whether this is due to endothelial dysfunction or impairment in the vascular smooth muscle remains unknown. Further, despite being a standard drug given to patients with cardiovascular disease, the role of an exogenous nitric oxide donor (sodium nitroglycerin – NTG, which acts independently of the endothelium) in the …
