Abstract
OBJECTIVE To evaluate arteriosclerosis using Cardio-Ankle Vascular Index (CAVI) and to explore the relation between the body fat percentage (BFP) and CAVI. DESIGN A retrospective observational study. SETTING AND PARTICIPANTS A total of 1152 patients admitted to a geriatric unit and general practice at a mega hospital in Wuhan, China, from November 2018 to November 2019 were included in this study. PRIMARY OUTCOME Association between BFP and CAVI. RESULTS Multiple linear regression analysis showed that BFP was positively correlated with CAVI after correction for potential confounding variables (β=0.03; 95% CI: 0.01 to 0.05); this association persisted after BFP was treated by quartile categorical variables and the trend test was statistically significant (p for trend=0.002). Meanwhile, the generalised additive model showed a non-linear association between BFP and CAVI. When BFP<20.6%, BFP is not associated with CAVI for (β=-0.02; 95% CI: -0.06 to 0.03), but when BFP≥20.6%, there is a linear positive association between BFP and CAVI (β=0.05; 95% CI: 0.02 to 0.07). Subgroup analysis showed that there was an interaction between BFP and CAVI in the age stratification (p interaction=0.038). CONCLUSION BFP was non-linearly correlated with CAVI, with a 0.05 increase in CAVI for every 1% increase in BFP when BFP≥20.6% and a 0.03 increase in CAVI in those >65 years of age.

[PMID: 35049240 PMCID: PMC9191392 DOI: 10.1097/md.0000000000028114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 11/16/2021] [Indexed: 11/26/2022] Open
Abstract
Body mass index (BMI) is positively associated with survival in heart failure (HF) patients with reduced ejection fraction (HFrEF). However, emerging evidence shows that this benefit may not exist in diabetic patients with HFrEF. As this relationship has not been investigated in Asian patients, the aim of this study was to examine the association between obesity and outcomes in HrEFF patients with and without diabetes mellitus (DM), and discuss the potential underlying mechanisms.The analysis included 900 patients with acute decompensated HF from the Taiwan Society of Cardiology-Heart Failure with Reduced Ejection Fraction Registry, of whom 408 had DM (45%). The association between BMI and all-cause mortality was examined using multivariate Cox proportional hazards regression after adjusting for covariates and Kaplan-Meier survival analysis. Echocardiography parameters were also analyzed in patients with different BMI and DM status.After adjusting for confounding factors, BMI was a significant independent predictive factor for all-cause mortality in the non-diabetic patients (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.81-0.95) and in Kaplan-Meier survival analysis (log-rank test, P = .034). For diabetic patients, BMI was not a significant predictive factor for all-cause mortality (HR, 0.96; 95% CI, 0.90-1.02) and in Kaplan-Meier survival analysis (log-rank test P = .169). Both DM (47.8 vs 45.4 mm, P = .014) and higher BMI (48.6 vs 44.9 mm, P < .001) are independently associated with higher left atrial size. Patients with a higher BMI had a lower proportion of severe mitral regurgitation (10.0% vs 14.1%, P < .001).In non-diabetic patients with HFrEF, BMI was a significant predictor of survival. However, in diabetic patients with HF, BMI was not a significant predictor of survival. Diastolic dysfunction in patients with DM and obesity may have played a role in this finding.

Abstract
Apparent resistant hypertension (ARH) is rife among people living with hypertension and is associated with significant morbidity and mortality. There is however paucity of data from sub-Saharan Africa on the burden of ARH. We sought to report on the frequency and factors associated with ARH among a cohort of Ghanaians with hypertension. A cross-sectional study involving 2912 participants with hypertension enrolled at five health facilities in Ghana. ARH was defined as either office BP ≥ 140/90 mm Hg on 3 or more antihypertensive medications or on 4 or more antihypertensive medications regardless of BP. Factors associated with ARH were evaluated in a multivariate logistic regression model. We found 550 out of 2,912 (18.9%) of study participants had ARH. Out of these 550 subjects, 511 (92.9%) were on 3 or more antihypertensive medications with BP ≥ 140/90 mm Hg and 39 (7.1%) were on 4 or more antihypertensive medications with BP ≥ 140/90 mm Hg. The prevalence of ARH was 15.5% among elderly aged 75 + years (n = 341), 20.7% among 65-74 years (n = 588), and 18.9% among those ≤ 64 years (n = 1983). The adjusted odds ratio (95% CI) of factors independently associated with ARH was duration of hypertension, 1.05 (1.03-1.06) for each year rise; eGFR < 60 mL/min, 1.73 (1.33-2.25); and diabetes mellitus, 0.59 (0.46-0.76). Attaining secondary level education and residence in a peri-urban setting were significantly associated with ARH though not in a dose-dependent manner. ARH is rife among Ghanaians and may negatively impact on cardiovascular outcomes in the long term.

Abstract
Pulse wave velocity (PWV) is a reliable measurement of arterial stiffness. Our study assesses the association between body mass index (BMI) and brachial-ankle PWV (baPWV) in a healthy cohort and seeks to explain possible mechanisms associated with the obesity paradox.A cross-sectional study was conducted in 578 normal individuals. The mean age was 48.3 ± 14.6 years, and 468 (81.0%) were men. 288 subjects (49.8%) were overweight and obese. baPWV and ankle-brachial index (ABI) were performed to evaluate arterial stiffness and atherosclerosis respectively. Normal weight was defined as 18.5 < BMI <25 kg/m, overweight as 25 ≤ BMI < 28 kg/m and obesity as BMI ≥28 kg/m.The overweight/obese subjects had significantly higher baPWV than the normal-weight group (1490.0 ± 308.0/1445.2 ± 245.2 cm/s vs 1371.2 ± 306.4 cm/s, P < .001). For the whole cohort, baPWV showed a significant positive correlation with BMI (r = 0.205, P < .001). However, baPWV was significantly lower as BMI increased: 1490.0 ± 308.0 cm/s (overweight); 1445.2 ± 245.2 cm/s (obese); P < .001) when adjusted for age, gender, heart rate, mean blood pressure, and cardiovascular risk factors (glucose, cholesterol, triglyceride, and low-density lipoprotein). For the whole cohort BMI was negatively associated with baPWV (β = -0.06, P = .042). ABI showed no relationship with BMI. In a middle-age healthy Chinese population, arterial stiffness measured as baPWV increased with BMI.Evidence of reduced arterial stiffness with increasing BMI when accounting for all other cardiovascular risk factors may contribute to underlying factors involved in the obesity paradox that becomes more prominent with increasing age.

Abstract
Background There were little national data on hypertension based on the oldest-old, and lack of information on chronological changes. This study aimed to describe trends of blood pressure (BP) levels and hypertension prevalence for the past 16 years among the oldest-old in China. Methods All the oldest-old who had participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) 1998 to 2014 with information about BP levels and hypertension were included in the analysis. Results There was fluctuation over the past 16 years for both SBP and DBP levels. The mean SBP level decreased from 148.4 ± 24.4 mmHg in 1998 to 130.8 ± 18.7 mmHg in 2005, and then increased to 139.7 ± 22.0 mmHg in 2014. The mean DBP level decreased from 84.3 ± 13.4 mmHg in 1998 to 78.9 ± 11.7 mmHg in 2008, and then increased to 79.7 ± 11.8 mmHg in 2014. The hypertension prevalence increased from 43.1 to 56.5% for the 16 years. The prevalence of isolated systolic hypertension was lowest in 2002–2005 (14.3%), and then increased to 30.7% in 2014. Multivariate logistic regression showed that older age, lower education and economic level, without health insurance were associated with higher hypertension prevalence. Conclusions There was a significant increase in hypertension prevalence among the Chinese oldest-old from 1998 to 2014. Greater efforts are needed for hypertension prevention among this specific population.

Abstract
Obesity is generally considered an undesirable risk factor for cardiovascular disease; however, obese subjects with heart failure paradoxically can have better outcomes than their lean counterparts. This study aimed to investigate this characteristic in an elderly Chinese population. Elderly participants (N = 414, age 77 ± 11 years, 211 males) were recruited from a Chinese community-dwelling elderly population. Subjects were divided into 3 groups according to body mass index (BMI ≤ 25, normal; 25-28, overweight; and ≥28, obese). Arterial stiffness was assessed by brachial-ankle pulse wave velocity (baPWV), and the atherosclerosis status was evaluated with the ankle brachial index (ABI). Brachial systolic blood pressure (BSBP) was significantly higher as BMI increased (135 ± 18.4, 138 ± 18.3, 147 ± 17.6 mm Hg; P = .003) adjusted for age, sex, and heart rate. However, baPWV was significantly lower as BMI increased (baPWV 1830 ± 18, 1793 ± 25, 1704 ± 36 cm/s; P = .008) in the three groups, even with additional adjustment for BSBP. BMI showed a significant negative correlation with baPWV (r = -.170, P = .001) after adjusting for confounding factors. Using multiple linear regression, BMI was negatively and independently associated with baPWV (β = -.190, P < .001) especially for age <80 years. Arterial stiffness, as measured by baPWV, is lower in overweight subjects in a Chinese elderly population compared to those with normal body weight. ABI showed no relationship with BMI. These findings suggest that reduced arterial stiffness in the overweight population, independent of confounding factors, may contribute to the explanation of the "obesity paradox."

Adipose afferent reflex is enhanced by TNFα in paraventricular nucleus through NADPH oxidase-dependent ROS generation in obesity-related hypertensive rats. J Transl Med 2019; 17:256. [PMID: 31391086 PMCID: PMC6686415 DOI: 10.1186/s12967-019-2006-0] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2019] [Accepted: 07/31/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The adipose afferent reflex (AAR), a sympatho-excitatory reflex, can promote the elevation of sympathetic nerve activity (SNA) and blood pressure (BP). Inflammation in the paraventricular nucleus (PVN) involves sympathetic abnormality in some cardiovascular diseases such as hypertension. This study was designed to explore the effects of tumor necrosis factor alpha (TNFα) in the PVN on the AAR and SNA in rats with obesity-related hypertension (OH) induced by a high-fat diet for 12 weeks. METHODS Renal sympathetic nerve activity (RSNA) and mean arterial pressure (MAP) were continuously recorded in anesthetized rats, and their responses to capsaicin (CAP) stimulation of the right inguinal white adipose tissue were used to evaluate the AAR. RESULTS Compared to the control rats, the systolic blood pressure (SBP), plasma norepinephrine (NE, indicating SNA) and TNFα levels, TNFα mRNA and protein levels, reactive oxygen species (ROS) content and NADPH oxidase activity in the PVN were significantly elevated in rats with OH. TNFα in the PVN markedly enhanced sympathoexcitation and AAR. Moreover, the enhancement of AAR caused by TNFα can be significantly strengthened by the pretreatment of diethyldithiocarbamate (DETC), a superoxide dismutase inhibitor, but attenuated by TNF-α receptor antagonist R-7050, superoxide scavenger PEG-SOD and NADPH oxidase inhibitor apocynin (Apo) in rats with OH. Acute microinjection of TNF-α into the PVN significantly increased the activity of NADPH oxidase and ROS levels in rats with OH, which were effectively blocked by R-7050. Furthermore, our results also showed that the increased levels of ROS, TNFα and NADPH oxidase subunits mRNA and protein in the PVN of rats with OH were significantly reversed by pentoxifylline (PTX, 30 mg/kg daily ip; in 10% ethanol) application, a cytokine blocker, for a period of 5 weeks. PTX administration also significantly decreased SBP, AAR and plasma NE levels in rats with OH. CONCLUSIONS TNFα in the PVN modulates AAR and contributes to sympathoexcitation in OH possibly through NADPH oxidase-dependent ROS generation. TNFα blockade attenuates AAR and sympathoexcitation that unveils TNFα in the PVN may be a possible therapeutic target for the intervention of OH.
