Our lab studies hormone systems that interact with central nervous system regulation during hypertension and heart failure, two cardiovascular disease conditions that have high mortality and morbidity. Primarily, the lab is focused on the link between hormonal systems (such as the renin angiotensin system), central sites of action of these hormones and the regulation of sympathetic nervous system outflow. We have focused our attention on the plasma hormone, angiotensin II, and examined its role in blood pressure regulation and the pathophysiology of heart failure at 3 specific brain regions (the area postrema, subfornical organ and organum vasculosum of the lamina terminalis) known as circumventricular organs. These areas lack the normal blood brain barrier and are therefore accessible by circulating peptide hormones. It is thought that hormones, such as angiotensin II act at these sites, cause downstream neural activation of the sympathetic nervous system, which in turn is linked to hypertension and chronic decreases in myocardial function after myocardial infarction. We use the rat as a model of hypertension or heart failure in our experiments. We also use state of the art radiotelemetry to continuously measure arterial pressure and heart rate in conscious, freely moving, rats for up to 6 months, and echocardiography to measure ejection fractions in rats with post myocardial infarctions. My collaborations involve direct interactions with physiologists, pathologists and cardiologists primarily but also I have a current collaboration with Dr. Al Beitz examining the effects of electroacupuncture on the long term hypertensive effects of angtiotensin II in the rat.
