Abstract
Apparent resistant hypertension, defined as uncontrolled office blood pressure despite ≥ 3 antihypertensive medications including a diuretic or use of ≥ 4 medications regardless of blood pressure, occurs in ≤ 15% of treated hypertensives. Apparent refractory hypertension, defined as uncontrolled office pressure despite use of 5 or more medications including a diuretic, occurs in ≤ 10% of resistant cases. Both are associated with increased comorbidity and enhanced cardiovascular risk. To rule out pseudo-resistant or pseudo-refractory hypertension, employ guideline-based methodology for obtaining pressure, maximize the regimen, rule out white-coat effect, and assess adherence. True resistant hypertension is characterized by volume overload and aldosterone excess, refractory by enhanced sympathetic tone. Spironolactone is the preferred agent for resistance, with lower doses. Spironolactone, potassium binders, or both, are preferred if the estimated glomerular filtration rate is below 45. If significant albuminuria, finerenone is indicated. The optimal treatment of refractory hypertension is unclear, but sympathetic inhibition (α-β blockade, centrally acting sympathoinhibitors, or both) seems reasonable. Renal denervation has shown minimal benefit for resistance, but its role in refractory hypertension remains to be defined.

Abstract
Aim. To study the effect of catheter-based sympathetic renal denervation (RDN) by radiofrequency ablation on glucose metabolism in patients with type 2 diabetes and uncontrolled hypertension.Material and methods. Sixty patients were randomly assigned in a 1:1 ratio to the RDN group and the control group. Radiofrequency ablation was performed through the femoral access using a Symplicity Spyral™ renal denervation system (Medtronic, USA).Results. The technical success was 100%. There were no any complications. During the follow-up period, patients in the RDN group showed a significant decrease in the average level of glycated hemoglobin — from 7,9 (6,83-8,35) to 6,85 (6,12-7,10)% (p<0,001) and basal glycemia — from 9,5 (7,17-10,28) to 7,55 (6,43-8,95) mmol/l (p<0,001) with no significant changes in the control group. Changes in glucose levels and the degree of insulin resistance correlated with a decrease in office systolic blood pressure (r=0,36, p=0,005). After 6-month follow-up period in the RDN group, along with a significant decrease in the HOMA-IR by 1,92 (p<0,001), the average high-density lipoprotein cholesterol level also significantly increased by 0,17 mmol/l (p<0,001), and mean triglyceride level decreased by -0,55 mmol/l (p<0,001).Conclusion. The study results confirm the hypothesis of pleiotropic effects of RDN in patients with comorbid pathology associated with central sympathetic nervous system hyperactivity (diabetes, hypertension, dyslipidemia).

COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:7889024. [PMID: 35936366 PMCID: PMC9348927 DOI: 10.1155/2022/7889024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 06/15/2022] [Accepted: 06/20/2022] [Indexed: 11/17/2022]
Abstract
Refractory hypertension seriously affects the life safety of patients. To investigate the effect of carvedilol combined with conventional antihypertensive therapy on blood pressure, blood sugar, blood lipids, and cardiovascular and cerebrovascular complications in elderly patients with refractory hypertension, a total of 80 elderly patients with refractory hypertension who were admitted from June 2019 to September 2021 were selected as the retrospective research objects and divided into the observation group and the control group according to the random number table method, 40 cases in each group, and the control group received conventional antihypertensive therapy. On this basis, the observation group was treated with carvedilol, and the effects of blood pressure, blood sugar, blood lipids, and cardiovascular and cerebrovascular complications were analyzed in the two groups. After treatment, the systolic blood pressure, diastolic blood pressure, adrenal medulla (AM), and endothelin (ET) of the observation group were significantly lower than those of the control group, but the heart rate and NO of the observation group were significantly higher than those of the control group. After treatment, the fasting blood glucose, insulin, triacylglycerol (TG), cholesterol (CHO), and low-density lipoprotein (LDL-C) of the observation group were significantly higher than those of the control group, but the ISI and HDL-C of the observation group were significantly lower than those of the control group. After treatment, the levels of IL-1β, IL-6, TNF-α, UAER, BUN, and SCr in the observation group were significantly lower than those in the control group. The TC of the observation group was lower than that of the control group. Combination therapy has a remarkably stable, sustained, and safe antihypertensive effect on patients with refractory hypertension.

Abstract
PURPOSE OF REVIEW To perform a narrative systematic review on refractory hypertension (RfHT) with particular emphasis on prognosis. RECENT FINDINGS There were 37 articles on RfHT, 13 non-systematic reviews, and 24 original studies. RfHT, a recently described extreme phenotype of anti-hypertensive treatment failure, shall be defined as uncontrolled out-of-office blood pressure (BP) levels despite the use of at least 5 anti-hypertensive drugs, including a long-acting diuretic and a mineraloreceptor antagonist. Its prevalence ranges from 0.5 to 4.3% of general treated hypertensives and between 3.6 and 51.4% of patients with resistant hypertension (RHT). RfHT is associated with younger age, African ancestry, obesity, hypertension-mediated organ damage and clinical cardiovascular diseases, and with some comorbidities, such as diabetes and obstructive sleep apnea. Its physiopathological mechanisms probably involve sympathetic overactivity and not volume overload. Patients with RfHT have a worse prognosis than non-refractory RHT individuals, with higher risks of adverse cardiovascular and renal outcomes and of mortality. RfHT represents a rare but true extreme phenotype of anti-hypertensive treatment failure distinct from RHT and with a significantly worse prognosis. Identifying such individuals is important to tailor specific interventions.

High carbohydrate high fat diet causes arterial hypertension and histological changes in the aortic wall in aged rats: The involvement of connective tissue growth factors and fibronectin. Exp Gerontol 2021; 154:111543. [PMID: 34455071 DOI: 10.1016/j.exger.2021.111543] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 08/23/2021] [Accepted: 08/23/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND Age and diabetes are risk factors for arterial hypertension. However, the relationship between age, connective tissue growth factors, vascular aging and arterial hypertension while on a the high-carbohydrate high-fat diet (HCHFD) remains poorly understood. PURPOSE To estimate the relationship between humoral factors, the morphological changes of aorta and impaired blood pressure regulation under the influence of age and a HCHFD. METHODS A study was carried out in male Wistar rats, which were divided into the following groups: 1st (n = 15) - naive young rats; 2nd (n = 15) - young rats, exposed to HCHFD; 3rd (n = 14) - naive old rats; 4th (n = 12) - old rats exposed to HCHFD. The age of old rats was 540 days, and young rats 150 days at the end of the diet. HCHFD contained proteins 16%, fats 21%, carbohydrates 46%, including 17% fructose, 0.125% cholesterol, 90 days. Blood pressure and body weight were measured weekly, carbohydrate metabolism, histological signs of changes in the aorta, serum transforming growth factor-β (TGF-β), connective tissue growth factor (CTGF), fibronectin, and endothelin-1 levels were determined one week after the onset of diet. RESULTS The severity of arterial hypertension and its histological signs in the aortic wall was found to be most pronounced in elderly rats kept on a HCHFD. In young rats kept on a HCHFD, arterial hypertension was transient. An increase in systolic blood pressure has a positive correlation with the degree of obesity, serum fibronectin, and endothelin-1 content, and impaired carbohydrate metabolism. The rise in diastolic blood pressure has a positive correlation with the serum CTGF, endothelin-1, fibronectin levels and aortic wall thickness, and impaired carbohydrate metabolism. A rise in the serum concentration of fibronectin was also associated with increased endothelin-1, TGFβ and CTGF serum levels. CONCLUSION This study indicated that an increase in blood pressure in old rats with a high-carbohydrate high-fat diet is due to a disturbance of a structure of the vascular wall, the release of fibronectin, which can occur under the influence of carbohydrate metabolism disorders, endothelin-1, TGFβ and CTGF.
