Proceedings from Duke resistant hypertension think tank.

To identify patients at increased risk for cardiovascular outcomes, apparent treatment resistant hypertension (aTRH) is defined as having a blood pressure (BP) above goal despite the use of ≥3 antihypertensive therapies of different classes at maximally tolerated doses, ideally including a diuretic. In light of growing scientific interest in the treatment of this group, a multistakeholder think tank was convened to discuss the current state of knowledge, improve the care of these patients, and identify appropriate study populations for future observational and randomized trials in the field. Although recent epidemiologic studies in selected populations estimate that the prevalence of aTRH is 10% to 15% of hypertensive patients, further large-scale observational studies will be needed to better elucidate risk factors. To spur the development of therapies for aTRH, the development of an "aTRH" label for pharmacologic and device therapies with a developmental pathway including treatment added to the use of existing therapies is favored. Although demonstration of adequate BP lowering should be sufficient to gain Food and Drug Administration approval for therapies targeting aTRH, assessment of improvement in quality of life and cardiovascular outcomes is also desirable and considered in Centers for Medicare and Medicaid Services coverage decisions. Device trials under the aTRH label will need uniform and consistent processes for defining appropriate patient populations as well as postapproval registries assessing both long-term safety and duration of responses. Finally, patients with aTRH are likely to benefit from evaluation by a hypertension team to assure proper patient identification, diagnostic work-up, and therapeutic management before consideration of advanced or novel therapies to lower BP.
