Abstract

OBJECTIVE: To determine causes of treatment resistance in patients with refractory hypertension, and to estimate the prevalence of true resistant hypertension. METHODS: We studied 50 consecutive patients referred with refractory hypertension after exclusion of hypokalemia and stenosis of the renal artery. Ambulatory blood pressure monitoring was performed in all patients to detect white-coat effect. The patients were hospitalized, antihypertensive drugs were withdrawn and a screening for secondary hypertension was performed. In addition, these patients, and a control group of essential hypertensives controlled with three antihypertensive drugs, underwent a OGTT with 75 g of glucose. RESULTS: Primary normokalemic hyperaldosteronism was diagnosed in seven patients. Two patients had a pheochromocytoma and six had white-coat effect. The 35 remaining patients with true resistant hypertension shown significant differences in serum insulin and HOMA IR when compared with the control group. CONCLUSIONS: These findings show that among normokalemic treatment-resistant hypertension, the presence of hyperaldosteronism and pheochromocytoma is quite high. Moreover, treatment resistance in hypertensive patients appears to be associated with insulin resistance.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
