Abstract
Importance Prehypertension increases the risk of developing hypertension and other cardiovascular diseases. Early and effective intervention for patients with prehypertension is highly important. Objective To assess the efficacy of Tai Chi vs aerobic exercise in patients with prehypertension. Design, Setting, and Participants This prospective, single-blinded randomized clinical trial was conducted between July 25, 2019, and January 24, 2022, at 2 tertiary public hospitals in China. Participants included 342 adults aged 18 to 65 years with prehypertension, defined as systolic blood pressure (SBP) of 120 to 139 mm Hg and/or diastolic BP (DBP) of 80 to 89 mm Hg. Interventions Participants were randomized in a 1:1 ratio to a Tai Chi group (n = 173) or an aerobic exercise group (n = 169). Both groups performed four 60-minute supervised sessions per week for 12 months. Main Outcomes and Measures The primary outcome was SBP at 12 months obtained in the office setting. Secondary outcomes included SBP at 6 months and DBP at 6 and 12 months obtained in the office setting and 24-hour ambulatory BP at 12 months. Results Of the 1189 patients screened, 342 (mean [SD] age, 49.3 [11.9] years; 166 men [48.5%] and 176 women [51.5%]) were randomized to 1 of 2 intervention groups: 173 to Tai Chi and 169 to aerobic exercise. At 12 months, the change in office SBP was significantly different between groups by -2.40 (95% CI, -4.39 to -0.41) mm Hg (P = .02), with a mean (SD) change of -7.01 (10.12) mm Hg in the Tai Chi group vs -4.61 (8.47) mm Hg in the aerobic exercise group. The analysis of office SBP at 6 months yielded similar results (-2.31 [95% CI, -3.94 to -0.67] mm Hg; P = .006). Additionally, 24-hour ambulatory SBP (-2.16 [95% CI, -3.84 to -0.47] mm Hg; P = .01) and nighttime ambulatory SBP (-4.08 [95% CI, -6.59 to -1.57] mm Hg; P = .002) were significantly reduced in the Tai Chi group compared with the aerobic exercise group. Conclusions and Relevance In this study including patients with prehypertension, a 12-month Tai Chi intervention was more effective than aerobic exercise in reducing SBP. These findings suggest that Tai Chi may help promote the prevention of cardiovascular disease in populations with prehypertension. Trial Registration Chinese Clinical Trial Registry Identifier: ChiCTR1900024368.

Prevalence of hypertension mediated organ damage in subjects with high-normal blood pressure without known hypertension as well as cardiovascular and kidney disease. J Hum Hypertens 2021; 36:610-616. [PMID: 34493835 DOI: 10.1038/s41371-021-00604-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 08/21/2021] [Accepted: 08/26/2021] [Indexed: 11/09/2022]
Abstract
Purpose of our study was to assess the prevalence of hypertension mediated organ damage (HMOD) in healthy subjects with high-normal Blood Pressure (BP) comparing them with subjects with BP values that are considered normal (<130/85 mmHg) or indicative of hypertension (≥140/90 mmHg). Seven hundred fifty-five otherwise healthy subjects were included. HMOD was evaluated as pulse wave velocity (PWV), left ventricular mass index (LVMI), and carotid intima-media thickness (IMT) and plaque. When subjects were classified according to BP levels we found that the high-normal BP group showed intermediate values of PWV and higher values of IMT. This corresponds to intermediate prevalence of arterial stiffness, while there were no differences for increased IMT or carotid plaque. No subjects showed left ventricular hypertrophy. At multivariable analysis, the odds of having arterial stiffness or carotid HMOD in the high-normal group resulted not different to the normal group. In conclusion, in our otherwise healthy population, high-normal BP values were not related to aortic, carotid or cardiac HMOD.

High Prevalence of Prehypertension and its Association with Modifiable Risk Factors: Findings of Household STEPS Survey from Urban Puducherry, South India. Int J Prev Med 2020; 11:162. [PMID: 33312471 PMCID: PMC7716600 DOI: 10.4103/ijpvm.ijpvm_6_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Accepted: 08/16/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Prehypertension increases the likelihood of hypertension, cardiovascular diseases, and renal failure, and it is amenable to control if it is detected early. The burden of prehypertension prevalent in the community is not much explored. This study aimed to estimate the prevalence and to identify the socio-behavioral and dietary factors related to prehypertension in South India. METHODS A community-based cross-sectional study was carried out where data related to socio-demographic status, substance use, dietary patterns, physical activity, and associated comorbidities were assessed using the WHO STEPwise survey tool. Adults aged >=18 years who were not previously diagnosed and treated for hypertension were assessed for prehypertension. Prevalence of prehypertension is reported as percentage with 95% CI. Association was reported as adjusted prevalence ratio obtained through multivariable log binomial regression adjusted for potential confounders. RESULTS Among 2399 participants, 2213 underwent screening. Among 2213 adults, 810 (36.6%, 95% CI: 34.6-38.6%) were in the prehypertension range. The adjusted prevalence for prehypertension was 36.2% among males and 37.2% among females, respectively. Being in the age group of 45-54 years aPR-1.36, body mass index (BMI) >23 Kg/m2 aPR-1.25, consumption of more than 6 grams of salt per day aPR-1.15 times were more likely to be associated with prehypertension. The comorbid conditions such as diabetes are less likely to be associated with prehypertension aPR-0.54 (0.41-0.72). CONCLUSIONS This community-based surveillance showed 36% of prehypertension among adults which would have been missed if we were to follow the routine cares such as opportunistic and high-risk-based screening. Since prehypertension increases the risk for various end organ failures, there is an impending need to focus on screening and promote healthy lifestyles.

Abstract
Background: Prehypertension is common in China, but its causes and associated factors have not been well studied. This study aimed to examine the age and gender-specific associations between CVD risk factor clustering and prehypertension among adults in China.Methods: This cross-sectional study used data from participants (n = 8735) aged over 45 in the China Health and Retirement Longitudinal Study (CHARLS) Baseline conducted from 2011-2012. The participants' data were collected using standard questionnaires, anthropometric, and biochemical tests. Logistic regression analyses were used to examine the associations between cardiovascular risk factors, their clustering and prehypertension.Results: Overall, 21.1%, 39.5%, 27.6% and 11.8% participants had 0, 1, 2, ≥ 3 CVD risk factors in prehypertension group, respectively. Diabetes and overweight/obesity were significantly associated with prehypertension (OR, 1.24; 95% confidence interval [CI], 1.06-1.44; OR, 1.55; 95% CI, 1.38-1.75) in the overall population, and diabetes was associated with prehypertension only in men (OR, 1.26; 95% CI, 1.00-1.58) and older adults (OR, 1.32; 95% CI, 1.03-1.69). Moreover, participants with 1, 2 and ≥3 risk factors had increased odds of having prehypertension (OR, 1.29; 95% CI, 1.12-1.49; OR, 1.59; 95% CI, 1.31-1.78; OR, 2.05; 95% CI, 1.66-2.53, respectively) and existed dose-response relationship, regardless of age and gender.Conclusions: This study indicated that CVD risk factor clustering was significantly associated with prehypertension and hypertension. These results provide valuable information for health professionals to better understand the impact of CVD risk factor clustering on prehypertension and hypertension.

Abstract
Previous studies have shown that allicin can lower blood pressure (BP) by reducing oxidative stress and inflammation. However, the association between habitual raw garlic intake (as allicin source) and prehypertension are unclear. The aim of this study was to investigate how raw garlic consumption is associated with prehypertension in an adult population. A cross-sectional study was conducted with 22,812 adults (mean [standard deviation] age: 39.4 [10.7] years; males, 47.7%) in Tianjin, China. Raw garlic consumption was assessed using a validated food frequency questionnaire. BP was measured at least twice by trained nurses using an automatic device. Prehypertension was defined as systolic BP of 120-139 mmHg and/or diastolic BP of 80-89 mmHg without taking antihypertensive medication. Multiple logistic regression models were used to assess the association between raw garlic consumption and prehypertension. The prevalence of prehypertension was 49.9%. After fully adjusting for potential confounders, the ORs (95% confidence intervals) of having prehypertension by increasing frequency of raw garlic consumption were 1.00 (reference) for ≤3 times/week, 0.96 (0.87, 1.06) for 4 times/week to 1 time/day, and 0.69 (0.52, 0.90) for ≥2 times/day (p for trend = 0.06). In contrast, no associations were observed between other kinds of allium vegetables consumption and prehypertension. In conclusion, our results suggested that a more frequent consumption of raw garlic was inversely associated with prehypertension. This is the first large-scale study on the association between raw garlic consumption and prehypertension in the general population.

Abstract
BACKGROUND Right ventricular (RV) morphology has been associated with drivers of atrial fibrillation (AF) risk, including left ventricular and pulmonary pathology, systemic inflammation, and neurohormonal activation. The aim of this study was to investigate the association between RV morphology and risk of incident AF. METHODS AND RESULTS We interpreted cardiac magnetic resonance imaging in 4204 participants free of clinical cardiovascular disease in the MESA (Multi-Ethnic Study of Atherosclerosis). Incident AF was determined using hospital discharge records, study electrocardiograms, and Medicare claims data. The study sample (n=3819) was 61±10 years old and 47% male with 47.2% current/former smokers. After adjustment for demographics and clinical factors, including incident heart failure, higher RV ejection fraction (hazard ratio, 1.16 per SD; 95% confidence interval, 1.03-1.32; P=0.02) and greater RV mass (hazard ratio, 1.25 per SD; 95% confidence interval, 1.08-1.44; P=0.002) were significantly associated with incident AF. After additional adjustment for the respective left ventricular parameter, higher RV ejection fraction remained significantly associated with incident AF (hazard ratio, 1.15 per SD; 95% confidence interval, 1.01-1.32; P=0.04), whereas the association was attenuated for RV mass (hazard ratio, 1.16 per SD; 95% confidence interval, 0.99-1.35; P=0.07). In a subset of patients with available spirometry (n=2540), higher RV ejection fraction and mass remained significantly associated with incident AF after additional adjustment for lung function (P=0.02 for both). CONCLUSIONS Higher RV ejection fraction and greater RV mass were associated with an increased risk of AF in a multiethnic population free of clinical cardiovascular disease at baseline.

Abstract
Background This study aimed to describe the prevalence and risk factors of prehypertension and hypertension in Jiangxi Province, China. Individuals with prehypertension frequently progress into hypertension and are at high risk of developing cardiovascular disease and stroke. Methods A cross-sectional survey of 15,296 participants (15 years or older) was conducted in Jiangxi Province, China, in 2013, using questionnaire forms and physical measurements. Results The prevalence of prehypertension and hypertension was 32.3% (39.2% in men and 27.6% in women) and 29.0% (30.1% in men and 28.2% in women), respectively. The awareness, treatment, and control rates among all hypertensive participants were 64.8%, 27.1%, and 12.6%, respectively. The prevalence of prehypertension in males declined with age, but the prevalence of hypertension increased in different genders. The prevalence of prehypertension and hypertension increased with increasing body mass index (BMI). The prevalence of prehypertension decreased, in parallel to an increase in the prevalence of hypertension, with increasing waist circumference (WC). A combination of WC and BMI was superior to individual indices in identifying hypertension. A multivariate logistic regression analysis indicated that increasing age, high BMI, high visceral adipose index, and high heart rate were risk factors for prehypertension and hypertension. The high body fat percentage was significantly associated with prehypertension. Living in an urban area, male sex, abdominal obesity, and menopause were correlated with hypertension. Conclusions Prehypertension and hypertension are epidemic in southern China. Further studies are needed to explore an indicator that can represent the visceral fat accurately and has a close relationship with cardiovascular disease.

Abstract
In this study, we have compared scintigraphic and echocardiographic data in order to investigate whether increased septal perfusion represents asymmetrical septal hypertrophy (ASH), which is a symptom followed in the scintigraphy of myocardial perfusion. The study consists of a total of 186 patients (120 females and 66 males with an average age of 59.45 ± 11.54 years) who had normal myocardial perfusion scintigraphy and echocardiography examinations. Statistical comparison of septal wall thickness measurements obtained from echocardiography and septal-to-lateral wall ratios (S/L ratio) was performed scintigraphically. Left ventricular mass values were obtained as both scintigraphic and echocardiographic data and their correlations were evaluated in order to assess the presence of left ventricular hypertrophy (LVH). In statistical analyses, the values of interventricular septal thickness in diastole (IVSd), left ventricle posterior wall thickness in diastole (LVPWd), left ventricle mass (LVM), and left ventricle mass index (LVMI) were found to be significantly higher in group 2 (S/L ratio >1) compared to group 1 (S/L ratio <1). In addition, S/L ratio is significantly correlated with echocardiographic IVSd, LVPWd, LVM, LVMI, and scintigraphic LVM (rest) values. Furthermore, echocardiographic LVM and LVMI values were significantly correlated with LVM and LVMI values obtained from scintigraphy. It should be known that increased S/L ratio that can be monitored during scintigraphic studies can be an indicator of septal hypertrophy and/or LVH, however, further examination and close follow-ups should be performed in necessary cases.

Abstract
The authors aimed to investigate the prevalence and risk factors of prehypertension among a cohort of patients presenting for a health check-up in Guangzhou. Using an age-and gender-stratified random sample method, 5170 urban adults aged 18-70 years undergoing health examination in Guangzhou were selected. Prehypertension was defined as systolic blood pressure (SBP) of 120-139 mmHg or diastolic blood pressure (DBP) of 80-89 mmHg. Overall prevalence of prehypertension in our study population was 35.15% (43.75% in men, 23.56% in women; P<0.05). Multivariate logistic regression analysis indicated that age (odds ratio [OR] =1.257), female (OR=0.437), fasting blood glucose (OR=1.514), total cholesterol (OR=1.241), triglycerides (OR=1.236), uric acid (OR=1.222), and body mass index (OR=1.778) were risk factors for prehypertension. The prevalence of prehypertension was reported to be higher among men in our study population in Guangzhou.

A Study on Effect of Electroacupuncture on Gene Expression in Hypothalamus of Rats with Stress-Induced Prehypertension Based on Gene Chip Technology. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2015; 2015:621237. [PMID: 26229544 PMCID: PMC4502326 DOI: 10.1155/2015/621237] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/11/2014] [Accepted: 03/02/2015] [Indexed: 02/01/2023]
Abstract
Objective. To explore the effect of electroacupuncture (EA) on gene expression in the hypothalamus of rats with stress-induced prehypertension and try to reveal its biological mechanism with gene chip technology. Methods. The stress-induced hypertensive rat model was prepared by combining electric foot-shocks with generated noise. Molding cycle lasted for 14 days and EA intervention was applied on model + EA group during model preparation. Rat Gene 2.0 Array technology was used for the determination of gene expression profiles and the screened key genes were verified by real-time fluorescence quantitative PCR method. Results. Compared with the blank group, 234 genes were upregulated and 73 were downregulated in the model group. Compared with the model group, 110 genes were upregulated and 273 genes were downregulated in model + EA group. The PCR results of the key genes including HSPB1, P2RX4, PPP1R14A, and TH are consistent with that of gene chip test. Conclusion. EA could significantly lower blood pressure of stress-induced prehypertension rats and affect its gene expression profile in hypothalamus. Genes and their signal transduction pathway that related to the contraction of vascular smooth muscle, concentration of Ca(2+), and excitability of sympathetic nerve may be involved in EA's antihypertensive mechanism.
