Orthostatic hypertension, which appears to be mediated through excess neurohumoral activation while standing, is a common blood pressure trait among patients with and without arterial hypertension. However, lack of consensus regarding the definition of orthostatic hypertension makes it difficult to assess the true prevalence of this condition. Orthostatic hypertension appears to predict the risk for progression to arterial hypertension in younger and risk of cardiovascular morbidity and mortality in older persons. Yet, the risk may differ between populations. Whether orthostatic hypertension indicates a generally increased risk of death, constitutes an intermediate variable in the causal pathway of cardiovascular risk factors, a simple measure of disease severity, or an independently acting mechanism is not known. Since both orthostatic hypotension and orthostatic hypertension herald increased risk of cardiovascular disease, it appears reasonable to screen the patients for abnormal orthostatic blood pressure responses using simple orthostatic testing. However, how presence of orthostatic hypertension may affect clinical management decisions such as the choice of antihypertensive drugs is currently difficult to ascertain. Clearly, this issue deserves more attention.

The prevalence of arterial hypertension (AH) increases with age: among people over 60 years old this index is more than 2 times higher in the general population, 2/3 of people over 65 years old suffer from hypertension. Among patients 65–89 years old with hypertension, 2/3 patients have isolated systolic hypertension (ISAG). Features of hypertension in the elderly patients are: lability of blood pressure (BP), increasing frequency of pseudohypertension, high frequency of «white coat hypertension», decreased sensitivity of pressor factors for antihypertensive drugs, high frequency of resistant to treatment of hypertension. The new recommendations of the European Society of Cardiology for the diagnosis and treatment of hypertension emphasize 2 groups of elderly patients: 65–79 years old and ≥80 years old, which described the epidemiological features, the prevalence of risk factors for cardiovascular events, blood pressure levels for antihypertensive therapy and target blood pressure, and the recommended principles of drug therapy that are different from young and middle-aged patients. For most patients, fixed combinations are indicated as starting AGT, but monotherapy is recommended for the treatment of hypertension in very elderly patients (over 80 years old) and elderly patients over 65 years old with senile asthenia. The decreasing of blood pressure should be gradual, taking into consideration the increased risk of orthostatic reactions at this age. European and American experts recommend os first-line drugs low doses of thiazide diuretics and calcium channel antagonists (mainly dihydropyridine), which are especially indicated in isolated systolic arterial hypertension to effectively reduce the frequency of cardiovascular complications in the treatment of elderly patients with hypertension.

Abstract Aim To study the dynamics of the prevalence, awareness, risk factors (RF) and treatment of arterial hypertension (AH) among men and women according to a survey of a representative sample of the population of the Ryazan region (RR) in 2007–2016. Materials and methods In 2002, as a part of the Russian epidemiological “EPOCH” study, a representative sample of the RR population (2098 people, average age 44.8±18.6 years) was formed and surveyed using step-by-step randomization of medical institutions, medical districts and apartments. A repeated survey of the sample was conducted in 2007 (1,760 people, response 83.9%) and in 2016 (1,497 people, response 85.1%). The AH group included persons with blood pressure ≥140/90 mmHg detected during the double measurement and with normal blood pressure while receiving antihypertensive therapy. In individuals with AH the risk factors were assessed: smoking, alcohol abuse, salt abuse, obesity, burdened family history, low physical activity. Results The prevalence of AH over the past 9 years has increased from 39.3% to 43.9%, p<0.001. The age-standardized prevalence of AH among women is higher than among men as in 2007 (42.1% versus 34.8%, p<0.001) and in 2016 (46.9% vs. 41.8%, p<0.05). Women's awareness about having AH increased from 83.9% to 88.9%, p<0.05, in men it decreased (84.0% against 77.4% in 2007, p>0.05). In the group of persons with AH, the more common risk factors are older age (56.8%), hereditary predisposition (58.9%), low physical activity (96.0%) and obesity (34.3%) compared with persons without AH (12.9%, 48.2%, 84.5% and 9.2%, respectively), they smoke less often (10.7% versus 23.2%) and use extra salt less often (29.5% against 38.4%), p<0.001. The number of patients taking antihypertensive drugs reached 91.2% against 84.0% in 2007, p<0.001. There was a decrease in the number of AH patients who: are treated intermittently (from 12.3% to 3.6%, p<0.001), who take drugs only when blood pressure is high (from 16.2% to 6.2%, p<0.001). The most frequently used antihypertensive drugs are still ACE inhibitors (64.8%), beta-blockers (48.9%), diuretics (42.5%), ARBs (29.2%) and calcium channel blockers (21.3%). The ratio of effectively treated AH patients increased in men from 14.6% to 27.8%, p<0.001, in women from 25.0% to 39.5%, p<0.001. A negative influence on the effectiveness of therapy was caused by smoking (RR 1.23; CI 1.11–1.37, p=0.005), salt abuse (RR 1.11; CI 1.06–1.23, p=0.04) and obesity (RR 1.16; CI 1.06–1.27, p=0.003). Conclusion Over the past nine years, the prevalence of hypertension in both the men and women has significantly increased in the Ryazan region. Increased treatment coverage and positive changes in drug therapy led to an increase in the number of effectively treated patients (from 21.4% to 35.5%, p<0.001). Obesity, smoking, salt abuse are associated with an increased risk of non-effectiveness of hypertension therapy.

Objective: Hypertension causes 7.5 million deaths annually worldwide. Antihypertensive drugs cause side effects, potentially leading to non-adherence, hence uncontrolled hypertension and increased risk of cardiovascular morbidity and mortality. Therefore, there has been increasing interest in alternative pharmacological treatments for hypertension, one of which is black cumin, or Nigella sativa, a traditional medicine that has been empirically used. This evidence-based case report aims to evaluate the current evidence for the effectiveness of Nigella sativa in reducing blood pressure in a mildly hypertensive patient. Methods: A literature search was performed on MEDLINE, TRIP Database, Clinical Key, ScienceDirect, and DynaMed, using the keywords “nigella sativa”, “hypertension”, and “blood pressure” with all their synonyms and related terms. The included studies were two systematic reviews and two clinical trials, which were then critically appraised. Results: Out of the four studies, three were considered valid. In terms of importance, Sahebkar et al. showed a reduction of the weighted mean difference (WMD) by Nigella sativa: −3.26 mmHg, 95% CI: −5.10, −1.42, I2 = 59% for systolic blood pressure and WMD: −2.80 mmHg, 95% CI: −4.28, −1.32, I2 = 60% for diastolic blood pressure. Badar et al. concluded that Nigella sativa significantly reduced systolic and diastolic blood pressure compared with the control group. Two studies were considered applicable to our patient in question. Conclusion: The current evidence for the effect of Nigella sativa in lowering blood pressure is limited. However, one study gives strong evidence for significant antihypertensive effects of Nigella sativa. In mild hypertension, Nigella sativa could be one of the therapeutic options.

Arterial hypertension (AH) is one of the most significant modifiable risk factors that increase cardiovascular morbidity and mortality worldwide, including Russia. The complex of structural and functional changes in the heart that occurs during AH consists not only in the formation of left ventricular (LV) myocardial hypertrophy, but also in the myocardial stiffness increasing due to collagen formation and cardiomyocytes apoptosis. These abnormalities are substrate for diastolic function disturbances, electrical myocardial instability and ischemia. The article provides a clinical case of amlodipine/lisinopril single-pill combination (A/L SPC) use in real clinical practice in a patient with stage II grade 2 newly diagnosed AH and its effect on blood pressure and echocardiographic myocardial fibrosis markers, including speckle tracking parameters The high antihypertensive efficacy of A/L SPC, a favorable effect on blood pressure circadian rhythm, as well as pronounced target-organ protective properties, in particular the ability to reduce LV and left atrial stiffness, were demonstrated. So, we conclude that A/L SPC improve the elastic properties of the left heart.

Abstract Objectives First generation baroreflex activation therapy (BAT) devices showed clinical efficacy in patients with drug-resistant arterial hypertension (AHT), but the safety profile was insufficient. Data regarding efficacy of second-generation devices were generated mostly from office blood pressure (BP) measurements or short-term 24-hour ambulatory blood pressure measurements (ABPM). We present a mid-term prospective registry to evaluate the efficacy and safety of recent BAT devices. Purpose The purpose of our study was to find a method that helps patients with drug-resistant arterial hypertension to control their blood pressure. Further we sought to reduce the overall amount of antihypertensive drugs to lessen side effects, as well as the effects of polypharmacy. Methods All patients receiving Barostim neo between November 2013 and June 2019 for resistant AHT were prospectively included into this observational study. ABPM was performed at baseline, in 3-month intervals in the first year after BAT implantation and in 6-month intervals afterwards for up to 42 months. Patients were assigned into two groups of responders and non-responders. Non-responders had a mean blood pressure drop (BPD) below 5mmHg. Responders in turn were categorized into 3 sub-groups (low-BPD between 5–9 mmHg, medium-BPD between 10–19 mmHg and high-BPD ≥20 mmHg). The primary efficacy end-points were changes in systolic and diastolic BP and number of antihypertensive medications. The primary safety end point was BAT-related major adverse events (MAE). Results 64 patients (mean age 63 years, 67% males) were included. Only patients who completed a 24-hour ABPM during a follow up were counted in the statistical analysis. We had an overall responder rate of 67.8%. Out of those 15.4% had low-BPD, 38.4% medium-BPD and 46.2% had a high-BPD. Systolic BP decreased over the 3.5-years period from 168±17 mmHg to 149±19 mmHg (n=19, mean change −18.8 mmHg; 95% confidence interval [CI]: −29.32 to −8.36; p&lt;0.0007). Diastolic BP decreased from 97±16 to 85±12 mmHg (n=19, mean change −11.7 mmHg; 95% CI: −19.2 to −4.2; p&lt;0.0021). The mean number of antihypertensive drugs was reduced from 6.9±1.3 to 5.2±1.5 (n=19, mean change −1.7; 95% CI: −0.8 to −0.27; p&lt;0.0009). The time course of primary end-points is shown in Fig.1. Freedom from BAT-related MAE was 93.5%. 4 perioperative complications (1 pocket bleeding, 1 pocket infection, 1 N. hypoglossus palsy, 1 hoarseness) resolved without residual side effects. There were five non BAT related deaths (7,8%) in the follow up period. Conclusion Systolic and diastolic ABP, as well as number and dosage of antihypertensive drugs decreased significantly during 3.5-years follow-up after Barostim neo implantation in 64 consecutive patients (of whom 62 completed at least one follow-up). No MAE associated with BAT were observed after the perioperative period. However, further controlled trials are needed to confirm the long-term efficacy of BAT. Figure 1.

Hypertension is the most important modifiable risk factor for primary and secondary stroke prevention. All antihypertensive drugs are effective in primary prevention: the risk reduction for stroke is 30—42%. However, not all classes of drugs have the same effects: there is some indication that angiotensin receptor blockers may be superior to other classes of antihypertensive drugs in stroke prevention. Seventy-five percent of patients who present to hospital with acute stroke have elevated blood pressure within the first 24—48 hours. Extremes of systolic blood pressure (SBP) increase the risk of death or dependency. The aim of treatment should be to achieve and maintain the SBP in the range 140—160 mmHg. However, fast and drastic blood pressure lowering can have adverse consequences. The PROGRESS trial of secondary prevention with perindopril + indapamide versus placebo + placebo showed a decrease in numbers of stroke recurrences in patients given both active antihypertensive agents, more impressive for cerebral haemorrhage.There were also indications that active treatment might decrease the development of post-stroke dementia.

Introduction: Visit-to-visit blood pressure variability (BPV) has been associated with greater cardiovascular and all-cause mortality, cognitive impairment, and incident dementia. It may also represent a decline in homeostatic mechanisms in blood pressure (BP) regulation associated with frailty, one of the most problematic expression of population aging. Hypothesis: We hypothesized that visit-to-visit systolic (SBPV), diastolic (DBPV), mean arterial (MAPV) and pulse pressure (PPV) variability are associated with greater incident frailty. Methods: We included 1,394 non-frail community-dwelling participants aged ≥ 70 years from the Multidomain Alzheimer Preventive Trial (MAPT) who underwent repeated clinical examinations over a 5-year follow-up period. SBPV, DBPV, MAPV and PPV were evaluated using standard deviation, coefficient of variation (CV), average real variability, successive variation, variation independent of mean and residual standard deviation. Incident frailty was assessed using the Fried phenotype. Cox proportional hazards models were used for the analyses. Results: Higher SBPV was significantly associated with increased risk of incident frailty (1-sd increase of CV: HR = 1.18, 95% CI [1.02-1.37], p=0.03) after adjustment for demographics, body mass index, stroke, ischemic heart disease, diabetes, heart failure, antihypertensive drugs, systolic BP, MAPT intervention groups and baseline pre-frail status. Similar results were observed with all indicators of variability. DBPV and MAPV were not associated with incident frailty (p=0.6 and p=0.2, respectively). Interestingly, higher PPV was also associated with a greater risk of developing frailty over time (1-sd increase of CV: HR = 1.17, 95% CI [1.01-1.35], p=0.03). Conclusion: Independently of BP, higher SBPV and PPV are major clinical predictors of incident frailty. Our findings support the concept of BP physiological dysregulation underlying the frail state and suggest that controlling BP instability could be a promising interventional target in preventing frailty.

Introduction: The association between high blood pressure (BP) and risk of death varies by age and appears to be attenuated in some elderly adults. Walking speed is an excellent measure of functional status and may identify which elders may be most at risk for the adverse consequences of hypertension. Hypothesis: We hypothesized that elevated BP would be associated with greater risk of mortality in faster walkers, but not in slower walkers. Methods: The study population included 2,340 persons ≥ 65 years, with measured BP, in the National Health and Nutrition Examination Survey (NHANES) waves 1999-2000 and 2001-2002. Mortality data was linked to death certificate data in the National Death Index. Walking speed was measured over a 20-foot walk; 243 (8%) did not complete the walk for various safety and logistical reasons. Participants with walking speed above the mean (2.7 ft/sec) were classified as faster walkers. Potential confouders included age, sex, race, survey year, lifestyle and physiologic factors, chronic health conditions, and antihypertensive use. Results: There were 589 deaths recorded through December 31 st , 2006. Among faster walkers, those with elevated systolic BP (≥140 mmHg) had a higher mortality rate compared to those with systolic BP <140 mmHg (236 vs. 161 per 100,000 person-years). Among slower walkers, mortality rates did not appear to differ by the presence of elevated systolic BP (586 vs. 563 per 100,000 person-years). This pattern remained after multivariable adjustment; there was an association between elevated systolic BP and mortality in faster, but not slower walkers (Table). Elevated diastolic BP was not independently associated with an increased risk of mortality. Conclusions: If confirmed in other studies, walking speed could be a simple measure to identify elderly adults who are most at risk for poor outcomes related to high blood pressure. Table Association of elevated blood pressure and mortality, stratified by walking speed Hazard Ratio (HR) of Death Faster Walking Speed >2.7 ft/sec (n = 1,279) Slower Walking Speed ≤ 2.7 ft/sec (n = 818) p-value for interaction HR (95% CI) p-value HR (95% CI) p-value Elevated Systolic BP (≥140 mmHg) 1.44 (1.04, 1.99) 0.03 1.08 (0.82, 1.42) 0.56 0.11 Elevated Diastolic BP (≥90 mmHg) 1.09 (0.52, 2.27) 0.82 0.65 (0.30, 1.45) 0.28 0.28 Funding (This research has received full or partial funding support from the American Heart Association, Western States Affiliate (California, Nevada&Utah))

Prazosin (Hypovase - Pfizer; Sinetens - Carlo Erba) is intended for the treatment of arterial hypertension. It is a quinazoline derivative and chemically unlike other antihypertensive drugs. The manufacturers claim that it works by relaxing arteriolar smooth muscle, which results in ‘smooth, gradual lowering of blood pressure’.

Abstract Background Blood pressure (BP) control is critical in delaying the progression of chronic kidney disease (CKD), which otherwise results in an increased risk of cardiovascular morbidity and mortality. Angiotensin II receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors, are recommended by several guidelines as first-line treatment for patients with hypertension and CKD. Purpose We reviewed and analysed the effect of ARB treatment on BP and renal outcomes (estimated glomerular filtration rate (eGFR), serum creatinine (SCr), creatinine clearance (CrCl) or proteinuria) in patients with hypertension and CKD with or without diabetes, including large clinical trials such as RENAAL and IDNT. Methods MEDLINE, EMBASE, and BIOSIS databases were searched for literature from the earliest available date to July 2017. Randomised (parallel-group) controlled trials of ≥8 weeks assessed the impact of ARBs on systolic/diastolic BP (SBP/DBP), eGFR, SCr, CrCl or proteinuria were included in the analysis. Meta-analysis (post- versus pre-treatment) and meta-regression were conducted in R-statistical software (v3.4.1) using meta- and metafor-packages. Mean difference (MD, generic inverse variance) with 95% confidence intervals (CIs) was used to pool data for an outcome in a single forest plot. The risk of bias (quality) of included studies was assessed by the six items of the Cochrane instrument. Results Of the 165 articles assessed for eligibility, 24 studies were included in the analysis (19 evaluated ARBs as monotherapy, 4 evaluated ARBs in combination with other antihypertensives and 1 evaluated ARBs both as mono- and combination therapy). Treatment with ARBs as monotherapy for ≥8 weeks to <1 year significantly reduced mean office SBP (MD, −12.60 mmHg; 95% CI, −18.53 to −6.67)/DBP (−6.52 mmHg; −11.27 to −1.77) (p<0.01). BP reduction was also significant (p<0.01) with ARB monotherapy for ≥1 year SBP (−14.84 mmHg; −17.82 to −11.85)/DBP (−10.27 mmHg; −12.26 to −8.27). ARBs also significantly reduced SBP/DBP when combined with other antihypertensive treatments for ≥8 weeks to <1 year as well as for ≥1 year (Figure). Moreover, ARBs induced significant reductions (p<0.01) in proteinuria (≥8 weeks to <1 year [MD, −0.6 g/L; 95% CI, −0.93 to −0.26; ≥1 year [−0.9 g/L; −1.22 to −0.59]), but no significant changes in eGFR, CrCl or SCr levels. The beneficial effect of ARBs was maintained overtime with no significant additional impact on SBP change (estimate: 0.025; 95% CI, –0.14 to 0.19) or eGFR (estimate: 0.068; 95% CI, −0.14 to 0.28; p=0.53). The overall risk of bias was judged to be low. Effect of ARBs on blood pressure changes Conclusion Treatment with ARBs effectively and sustainably lowered BP and proteinuria with no significant change in eGFR in patients with hypertension and CKD with or without diabetes.
