Currently we are funded by the National Heart Lung and Blood Institute (NHLBI) of the National Institutes of Health and the American Heart Association to perform research grants investigating the role of circulatory dysfunction and respiratory dysfunction in postural tachycardia syndrome (POTS). Further NIH funding for studies of specific central nervous system effects of nitric oxide and angiotensin are pending as does a renewal of CFS funding.

We have solicited patients for the POTS study since September 2004 and this is on-going although the precise experiments have changed to include basic mechanisms of central nervous system control of blood pressure in subsets of POTS patients. Additionally we have observed similarities among findings in low flow POTS patients and in patients with forms of kidney disease with and without renal failure, and in young subjects with obesity related metabolic syndrome both of which are the subjects of funded investigations.
