This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Patients with metabolic syndrome, characterized primarily by insulin resistance are at increased risk of developing diabetes and often have hypertension-HTN. Thiazide diuretics are recommended for treating HTN in patients with metabolic syndrome, despite being associated with metabolic disturbances that result in increased insulin resistance. The major hypothesis of this study is that in patients with metabolic syndrome and HTN, blockade of the renin-angiotensin system-RAS with an angiotensin converting enzyme-ACE inhibitor attenuates the adverse metabolic effects of a thiazide diuretic.
Specific aims are designed to investigate whether this attenuation occurs after the addition of ACE inhibitor to diuretic and/or as a consequence of pretreatment with an ACE inhibitor. Also, laboratory based pharmacogenomic investigations will be conducted in a separate cohort of 6000 hypertensive CAD patients to identify polymorphisms associated with diabetes in the ACE, ADD1 and KCNJ1 genes, selected on the basis of their critical role in ACE inhibitor and diuretic response. This research seeks to overcome gaps in knowledge regarding the metabolic impact of antihypertensive drugs in patients with metabolic syndrome and will provide data to influence future prescribing patterns.
