Modulation of Vascular Function
Professor Peter Collins, Principal Investigator
Research efforts of this group concentrate on the investigation of vascular function in health and disease, with particular emphasis on coronary heart disease and modulation of endothelial function. Specifically, research has focussed on the investigation of a variety of hormones and related substances in isolated blood vessels and cardiac myocytes, and on the coronary and peripheral circulations of humans. Dietary modulation of vascular function and exercise performance is also being investigated.
Women’s heart health
Research investigating the actions of sex hormones on the cardiovascular system in women has led to an interest in women’s heart health. Chest pain syndromes such as cardiac syndrome X are more prevalent in women and a particular interest has developed to investigate new therapeutic options in this troublesome syndrome associated with considerable morbidity.
In collaboration with the MRI unit, a novel methodology has been pioneered and validated for the measurement of brachial artery endothelial function. The group has validated the use of radial artery applanation tonometry to measure endothelial function.
