Background Capsaicin has been shown to exert direct vasodilating effects through increased calcitonin gene-related peptide (CGRP) release. However, no data exist on its effect following systemic administration in humans. Methods Twelve male patients with stable coronary disease and a persistently positive exercise were selected for study. According to a double blind, placebo-controlled, cross-over study, patients were randomized to placebo or 3 g oleic capsaicin-containing patches, on 2… 

A Randomized, Placebo‐Controlled Study of the Effects of Telcagepant on Exercise Time in Patients With Stable Angina

The hypothesis that telcagepant does not reduce TET was supported if the lower bound of the two‐sided 90% confidence interval (CI) for the mean treatment difference (telcagespant–placebo) in T ET was more than −60 s.

A reactive oxygen species-mediated component in neurogenic vasodilatation.

In vivo evidence that ROS are involved in mediating TRPV1- and neuropeptide-dependent neurogenic vasodilatation is provided, and an essential role of NADPH oxidase-dependent ROS is revealed that may be of fundamental importance to the neurogenic Vasodilator component involved in circulatory homeostasis and the pathophysiology of certain cardiovascular diseases.

Effect of Capsaicin Supplementation on Performance of and Physiological Response to Repeated Sprinting

Capsaicin did not influence repeated sprint performance or the inflammatory response, but reduced HR during intense activity and causes substantial GD.

Capsaicin may have important potential for promoting vascular and metabolic health

In rodent studies, capsaicin-rich diets have shown favourable effects on atherosclerosis, metabolic syndrome, diabetes, obesity, non-alcoholic fatty liver, cardiac hypertrophy, hypertension and stroke risk and further clinical studies are needed to establish protocols that are tolerable for most patients, and to evaluate the potential of Capsaicin for promoting vascular and metabolic health.

Capsaicin and TRPV1 Channels in the Cardiovascular System: The Role of Inflammation

This review focuses on vascular TRPV1 channels that are endogenously expressed in both vascular smooth muscle and endothelial cells and emphasizes the role of inflammation in sensitizing the TRpV1 channel to capsaicin activation.

Harnessing the Therapeutic Potential of Capsaicin and Its Analogues in Pain and Other Diseases

This review summarizes the historical background, source, structure and analogues of capsicin, and capsaicin-triggered TRPV1 signaling and desensitization processes and will focus on the therapeutic roles of Capsaicin and its analogues in both normal and pathophysiological conditions.

The effect of 4-week chilli supplementation on metabolic and arterial function in humans

Four weeks of regular chilli consumption has no obvious beneficial or harmful effects on metabolic parameters but may reduce resting heart rate and increase effective myocardial perfusion pressure time in men.

Dietary Capsaicin: A Spicy Way to Improve Cardio-Metabolic Health?

It is concluded that although a chili pepper-rich diet is associated with a reduced risk of dying due to cardiovascular disease, dietary capsaicin has no clear effect on blood glucose or lipid profiles, and the reduced mortality risk may reflect the beneficial action of digested Capsaicin on gut microbiota.

Erectile Dysfunction in Coronary Artery Disease and Heart Failure

Although sexual activity is not contraindicated in these patients, men with HF should receive detailed cardiologic assessment before having sexual intercourse, and the administration of phosphodiesterase type-5 inhibitors for the treatment of ED might counteract endothelial dysfunction and decrease fibrosis, apoptosis, and hypertrophy.

Results suggest that capsaicin can dilate microvessels by releasing CGRP, which can modulate tone, which is consistent with the hypothesis that this agent causes depletion of an endogenous vasodilator.
