Koracevic G, Micic S, Stojanovic M, Zdravkovic M. A Need for Improvement in the Definition of Resistant Arterial Hypertension. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:803. [PMID: 37109761 PMCID: PMC10145005 DOI: 10.3390/medicina59040803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 04/12/2023] [Accepted: 04/18/2023] [Indexed: 04/29/2023]
Abstract
With the medical and social importance of resistant arterial hypertension (HTN) in mind, we had three goals in this paper: to study the definitions of resistant HTN in the guidelines on the topic, to analyze them, and to suggest some improvements. We found (at least) eleven insufficiencies in the definition of resistant HTN: (1) different blood pressure (BP) values are used for diagnoses; (2) the number of BP measurements is not specified; (3) the time-frame for the definition is not obtained; (4) it fails to provide normal or target or controlled BP values; (5) secondary HTN is not currently defined as true resistant HTN, but as apparently treatment-resistant HTN; (6) the definition usually directly incorporates BP cut-offs for systolic BP (sBP) and diastolic BP (dBP) making the diagnosis temporary; (7) stress is not included in the exclusion strategy for resistant HTN; (8) there is potentially a need to introduce a category of recovered resistant HTN; (9) to what degree do healthy lifestyle measures have to be fulfilled to consider it as sufficient to change the diagnosis from "apparent treatment-resistant HTN" to the "resistant HTN"; (10) sBP values normal-for-the-age for 61 and 81 year old patients in some guidelines fulfill the criterion for resistant HTN; (11) it probably ought to read "In the absence of contraindications and compelling indications…" in the others. We believe that it is better to use the phrase "above the target BP" for the definition of (treatment) resistant HTN, because the whole story of resistant HTN is related to non-responders to antihypertensive treatment. Therefore, as we treat to target and not to normal values, it is appropriate to define resistant HTN as an insufficiency to reach the target BP values. Moreover, the definition of (treatment) resistant HTN should not be universal for every patient with HTN, but it should be age-related: (treatment) resistant HTN is elevated BP over the target/normal BP values. Using this modification, there will be no need to automatically change the definition of resistant HTN when we change the BP targets in the future.

Abstract
Patients with masked hypertension (MH) and masked uncontrolled hypertension (MUCH) are easily overlooked, and both cause target organ damage. We propose a prediction model for MH and MUCH patients based on clinical features at a single outpatient visit. Data collection was planned before the index test and reference standard were after. Thus, we retrospectively collect analyzed 804 subjects who underwent ambulatory blood pressure monitoring (ABPM) at Renmin Hospital of Wuhan University. These patients were divided into normotension/controlled hypertension group (n = 121), MH/MUCH (n = 347), and sustained hypertension (SH)/sustained uncontrolled hypertension group (SUCH) (n = 302) for baseline characteristic analysis. Models were constructed by logistic regression, a nomogram was visualized, and internal validation by bootstrapping. All groups were performed according to the definition proposed by the Chinese Hypertension Association. Compared with normotension/controlled hypertension, patients with MH/MUCH had higher office blood pressure (BP) and were more likely to have poor liver and kidney function, metabolic disorder and myocardial damage. By analysis, [office systolic blood pressure (OSBP)] (P = .004) and [office diastolic blood pressure (ODBP)] (P = .007) were independent predictors of MH and MUCH. By logistic regression backward stepping method, office BP, body mass index (BMI), total cholesterol (Tch), high-density lipoprotein cholesterol (HDL-C), and left ventricular mass index are contained in this model [area under curve (AUC) = 0.755] and its mean absolute error is 0.015. Therefore, the prediction model established by the clinical characteristics or relevant data obtained from a single outpatient clinic can accurately predict MH and MUCH.

Prevalence and clinical characteristics of primary aldosteronism in a tertiary-care center in Korea. Hypertens Res 2022; 45:1418-1429. [PMID: 35681044 DOI: 10.1038/s41440-022-00948-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Revised: 05/11/2022] [Accepted: 05/13/2022] [Indexed: 11/08/2022]
Abstract
Approximately 29% of Korean adults have hypertension; however, the prevalence of primary aldosteronism among the hypertensive population is largely unknown. The aim of our study was to evaluate the prevalence and clinical characteristics of primary aldosteronism in a tertiary-care center in Korea. We retrospectively analyzed 1173 patients with newly diagnosed or preexisting hypertension who were referred to our tertiary-care hospital between January 2013 and December 2018. Patients were screened for primary aldosteronism with the aldosterone-renin ratio and underwent a saline infusion test for diagnostic confirmation. Adrenal computed tomography and adrenal venous sampling were performed for subtype classification for primary aldosteronism. Among the 1173 patients (mean age, 51.8 years; women, 53.2%), 360 (30.7%) had positive screening-test results, of whom 71 (6.1%) were finally diagnosed with primary aldosteronism. Conclusive subtype differentiation was made in 55 patients, of whom 15 (27%) had an aldosterone-producing adenoma, 4 (7%) had unilateral adrenal hyperplasia, and 36 (66%) had bilateral adrenal hyperplasia. Patients with primary aldosteronism had a higher ambulatory blood pressure, left ventricular mass index, and urinary albumin-to-creatinine ratio than those without. Moreover, the primary aldosteronism group had a higher prevalence of left ventricular hypertrophy and albuminuria than the non-primary aldosteronism group. Primary aldosteronism may be more common (6.1%) among Korean patients with hypertension than generally recognized. Primary aldosteronism was associated with a higher degree and prevalence of target organ damage and a higher blood pressure level. Wide application of screening tests for primary aldosteronism may be beneficial in detecting this potentially curable cause of hypertension.

Abstract
The prognosis of refractory hypertension is largely unknown due to its low prevalence. This study aimed to investigate the prognosis of refractory hypertension and compare it with those of resistant and nonresistant hypertension. We retrospectively analyzed the data of 16,284 participants with hypertension who underwent ambulatory blood pressure (BP) monitoring between 2012 and 2019 at a tertiary center. Uncontrolled BP was defined as a 24-h BP ≥ 130/80 mmHg as assessed by ambulatory BP monitoring. Resistant hypertension was defined as uncontrolled BP despite the use of three antihypertensive medications, including a diuretic or the use of ≥4 drugs regardless of BP control. Refractory hypertension was defined as uncontrolled BP despite the use of ≥5 antihypertensive medications. Among 16,284 patients with hypertension (mean age 59.2 ± 15.5 years, 52.7% men), 1501 (9.2%) and 150 (0.9%) patients had resistant and refractory hypertension, respectively. The prevalence of chronic kidney disease, end-stage renal disease, heart failure, previous stroke, left ventricular hypertrophy, and the riser/nondipper patterns of circadian BP rhythm progressively increased from patients with nonresistant hypertension to patients with resistant hypertension to patients with refractory hypertension. During a median follow-up of 3.9 years, the risk of cardiovascular mortality progressively increased from patients with nonresistant hypertension to patients with resistant hypertension (hazard ratio 1.62, 95% confidence interval 1.16-2.26) to patients with refractory hypertension (hazard ratio 5.22, 95% confidence interval 3.04-8.96). In conclusion, refractory hypertension, defined as uncontrolled ambulatory BP levels, was associated with a higher risk of all-cause and cardiovascular mortality than nonresistant or resistant hypertension.
