Abstract
BackgroundMetabolic syndrome is a pre-diabetes condition that is associated with increased cardiovascular morbidity and mortality. We aimed to explore how exercise capacity, cardiac structure, and function were affected in patients with metabolic syndrome.MethodsOutpatients with echocardiography and exercise stress test combined with impedance cardiography (ETT + ICGG) results available from Nov 2018 to Oct 2020 were retrospectively enrolled. Echocardiographic, ETT + ICG profiles, and exercise performance were compared between patients with metabolic syndrome and the ones without. Sensitivity analyses were performed excluding patients without established coronary heart disease and further 1:1 paired for age and gender, respectively. Multiple linear regression was used to find out related predictors for maximal metabolic equivalents (METs).ResultsThree hundred and twenty-third patients were included, among whom 97 were diagnosed as metabolic syndrome. Compared to patients without metabolic syndrome, echocardiography showed that patients with metabolic syndrome had a significantly lower E/A ratio (p < 0.001). Besides, they have larger left atrium, larger right ventricle, and thicker interventricular septum (all p < 0.001), but similar left ventricular ejection fraction (P = 0.443). ICG showed that patients with metabolic syndrome had significantly higher stroke volume at rest and maximum (p < 0.001), higher left cardiac work index at rest and maximum (p = 0.005), higher systemic vascular resistance (SVR) at rest (p < 0.001), but similar SVI (p = 0.888). During exercise, patients with metabolic syndrome had lower maximal METs (p < 0.001), and a higher proportion suffering from ST-segment depression during exercise (p = 0.009). Sensitivity analyses yielded similar results. As for the linear regression model, 6 independent variables (systolic blood pressure, BMI, E/A ratio, the height of O wave, the peak value of LCWi, and the baseline of SVR) had statistically significant effects on the maximal METs tested in exercise (R = 0.525, R2 = 0.246, P < 0.001).ConclusionPatients with metabolic syndrome had significant structural alteration, apparent overburden of left ventricular work index, pre-and afterload, which may be the main cause of impaired exercise tolerance.

Quantification and Verification of Cardiorespiratory Fitness in Adults with Prehypertension. Sports (Basel) 2021; 9:sports9010009. [PMID: 33440896 PMCID: PMC7827435 DOI: 10.3390/sports9010009] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 01/02/2021] [Accepted: 01/06/2021] [Indexed: 12/31/2022] Open
Abstract
Background: Low cardiorespiratory fitness is associated with increased risk of hypertension and atherosclerosis in adults with prehypertension. The purpose of this study was to quantify cardiorespiratory fitness and to examine the utility of supramaximal constant-load verification testing for validating maximal oxygen uptake (VO2max) attainment in adults with prehypertension. Methods: Eleven adults (four women) with prehypertension (22.5 ± 2.9 y; body mass index (BMI): 24.6 ± 3.2 kg·m2) underwent an incremental exercise test followed 15 min later by a verification test at 105% of maximal work rate on a cycle ergometer. Results: There was no statistical difference in VO2 between the incremental (2.23 ± 0.54 L·min−1) and verification tests (2.28 ± 0.54 L·min−1; p = 0.180). Only three out of eleven participants had a higher VO2 during the verification when compared with the incremental test. If the verification test had not been conducted, one participant would have been incorrectly classified as having low cardiorespiratory fitness based on incremental test results alone. Conclusions: Verification testing validates the attainment of VO2max and can potentially reduce the over-diagnosis of functional impairment (i.e., deconditioning) in adults with prehypertension.

Ahn N, Kim K. Can Active Aerobic Exercise Reduce the Risk of Cardiovascular Disease in Prehypertensive Elderly Women by Improving HDL Cholesterol and Inflammatory Markers? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17165910. [PMID: 32824020 PMCID: PMC7459903 DOI: 10.3390/ijerph17165910] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Revised: 08/11/2020] [Accepted: 08/12/2020] [Indexed: 12/22/2022]
Abstract
This study aims to verify the efficacy of exercise programs designed to prevent and treat hypertension-induced cardiovascular disease (CVD) by analyzing the effects of a 6-month active aerobic exercise program, administered to prehypertensive elderly women, on reducing the risk of developing CVD by enhancing their physical fitness level and improving the detailed markers of high-density lipoprotein cholesterol (HDL-C) and inflammatory markers. We assigned the elderly women (≥65 years) recruited into normal blood pressure (120–129/80–84; NBP, n = 18) and high-normal blood pressure (130–139/85–89; HNBP, n = 12) groups according to the European guidelines for the management of arterial hypertension. The exercise program was made up of combined workouts of elastic band resistance exercise and aerobics with dance music. The program took place three times a week for six months, with each session lasting 60 min. We measured pre- and post-intervention body composition, blood pressure, physical fitness level, blood lipids profile, HDL-C, SAA, TNF-α, IL-6, IL-4, IL-15, CRP, and HSP70 and calculated the Framingham risk scores for comparison. A significant post-intervention reduction in the mean systolic blood pressure (SBP) was observed in the HNBP group (p < 0.001), with significant increase in HDL-C (p < 0.01) and significant decrease in serum amyloid A (SAA) concentration (p < 0.01). A significant improvement in physical fitness factors such as physical efficiency index (PEI) was also observed in the HNBP group (p < 0.05). The post-intervention TNF-α, IL-6, and SAA concentrations were more significantly lower in the HNBP than in the NBP group (p < 0.05). Compared to the baseline values, a significant decrease in SAA concentration (p < 0.01) and significant increase in HSP70 concentration (p < 0.001) were observed in the HNBP group. The HNBP group’s 10-year CVD risk was also significantly reduced (p < 0.05). The pre–post differences in SBP and DBP were significantly correlated with those in the anti-inflammatory markers IL-4 and IL-15 (p < 0.01). In conclusion, the 6-month active aerobic exercise program of moderate intensity administered to prehypertensive elderly women (≥65 years) had the effect of reducing the 10-year CVD risk through a substantial reduction in SBP, overall physical fitness improvement, increase in HDL-C, decrease in SAA concentration, and substantial decrease in inflammatory biomarkers. It was also confirmed that an increase in anti-inflammatory markers, which showed a small range of increase with respect to the decrease in blood pressure, may have a major effect.

Abstract
Although the American College of Cardiology/American Heart Association guidelines have introduced a novel definition of hypertension in their 2017 hypertension guidelines, the influence of novel stage 1 hypertension on cerebrovascular diseases remains unclear. In this study, we evaluated the relationship between stage 1 hypertension, as defined by the 2017 American College of Cardiology/American Heart Association guidelines and cerebral small vessel disease in a healthy population. We assessed consecutive health checkup participants without the use of antihypertensive medication between 2006 and 2013. White matter hyperintensity volumes were rated using semiautomated quantitative methods. The presence of lacunes, cerebral microbleeds, and enlarged perivascular spaces was also measured as cerebral small vessel disease lesions. We classified the blood pressure of all participants according to the 2017 American College of Cardiology/American Heart Association guidelines. A total of 2460 participants were evaluated. In adjusted linear and logistic regression analyses, stage 1 hypertension was independently associated with white matter hyperintensity volume (β=0.158; 95% CI, 0.046-0.269; P=0.006), presence of lacune (adjusted odds ratio, 1.66; 95% CI, 1.00-2.73; P=0.048), and deep cerebral microbleeds (adjusted odds ratio, 2.50, 95% CI, 1.08-5.79; P=0.033). Stage 2 hypertension showed higher coefficients or adjusted odds ratio values and lower P values in all analyses of white matter hyperintensity volumes, lacunes, and deep cerebral microbleeds, indicating dose-response effects across blood pressure categories. Stage 1 hypertension according to the 2017 American College of Cardiology/American Heart Association guidelines is associated with cerebral small vessel disease lesions, especially in white matter hyperintensity lesions, lacunes, and deep cerebral microbleeds.

Abstract
AIMS Obesity induces left ventricular diastolic dysfunction and ultimately causes heart failure. Sarcopenic obesity is common in heart failure with preserved ejection fraction (HFpEF). However, the precise mechanism by which sarcopenic obesity is related to HFpEF is poorly understood. We aimed to evaluate the combined effect of sarcopenia (SP) and obesity on left ventricular diastolic function and exercise capacity. METHODS This study included 733 healthy subjects who underwent health check-ups in a tertiary hospital in Korea. All participants were categorized into four groups: non-SP/non-obese, SP/non-obese, non-SP/obese, and SP/obese. Comprehensive echocardiography with cardiopulmonary exercise testing was performed. Diastolic dysfunction was defined as an E/e' ratio ≥ 10. RESULTS Across SP and obesity groups, a gradual decrease in e' velocity and an increase in the E/e' ratio was noted after adjustment for age and sex. Furthermore, a gradual decrease in percent-predicted peak VO2 was observed across the groups. In the multivariate logistic regression analysis, the SP/obese group had the highest risk for diastolic dysfunction (OR 4.27, 95% CI 2.41-7.57), followed by the non-SP/obese group (OR 2.88, 95% CI 1.57-5.29) and the SP/non-obese group (OR 1.90, 95% CI 1.01-3.56) compared with the reference (non-SP/non-obese) group even after controlling for various confounders. CONCLUSION Sarcopenic obesity was associated with impaired diastolic function and decreased exercise capacity, suggesting a possible mechanism by which sarcopenic obesity contributes to the development of HFpEF.

Abstract
Background Physical inactivity is an important but often neglected risk factor for various cardiovascular diseases. We hypothesized that physical inactivity might have deleterious effects on metabolic health in obese and non-obese subjects. Methods We evaluated the effect of physical activity on the cardiometabolic profiles of a nationwide cohort of non-obese and obese individuals who did not have overt cardiovascular diseases. A total of 3,830 study subjects were divided into two groups based on their body mass index (BMI). Within each BMI group, participants were divided according to their physical activity level. To ascertain their cardiometabolic profiles, we collected data regarding the homeostasis model assessment-estimated insulin resistance (HOMA-IR) index, high-density lipoprotein (HDL)-cholesterol level, systolic blood pressure, heart rate, and high-sensitivity C-reactive protein (hsCRP) level. Results Physically inactive subjects demonstrated markedly elevated HOMA-IR index and heart rates in each BMI category, even after adjustments for baseline covariates. They also tended to have worse profiles for HDL-cholesterol, systolic blood pressure, and hsCRP levels. A significant elevation in cardiometabolic risk was noted across the four physical activity/obesity groups (p<0.05). HOMA-IR index was largely affected by obesity, but within each BMI category, physical inactivity independently elevated the risk for worsening insulin resistance. In addition, physical inactivity significantly increased the risk of elevated heart rate in both non-obese and obese individuals. Notably, the detrimental effect of physical activity on heart rate was not modified by obesity. Conclusions Physical activity was associated with favorable cardiometabolic risk profiles with regard to insulin resistance status and heart rate level in both BMI groups. Our results suggest that increasing physical activity could be a helpful strategy for improving the cardiometabolic health in the Korean population, regardless of obesity status.

Abstract
OBJECTIVES To determine whether high heart rate is associated with low bone mineral density (BMD) in older women with hypertension. DESIGN Retrospective cohort study. SETTING Population-based study conducted in Korea (Korea National Health and Nutritional Examination Survey 2009-10). PARTICIPANTS Postmenopausal women aged 60 and older with hypertension (N=981) divided into 2 groups according to resting heart rate, with a cut-off value of 80 bpm, which has been found to be associated with osteoporosis. MEASUREMENTS BMD profiles and clinical and laboratory data were collected. Osteoporosis was defined as a T-score of -2.5 or less, according to World Health Organization criteria. RESULTS BMD was significantly lower in participants with a high heart rate, even after adjustment for age, diabetes mellitus, white blood cell count, and fasting glucose and triglyceride levels. The prevalence of osteoporosis was also significantly higher in those participants. In multivariate logistic regression analysis, the group with high heart rate was 1.7 times as likely (95% confidence interval=1.2-2.3) to have osteoporosis as those with a lower heart rate, independent of age, body mass index, comorbidities, and laboratory findings. CONCLUSION High heart rate is independently associated with lower BMD in older women with hypertension; proactive surveillance of BMD could be helpful when managing older women with hypertension and a high heart rate.

Abstract
Cardiovascular diseases are the leading cause of death. The underlying pathophysiology is largely contributed by an overactivation of the renin-angiotensin-aldosterone-system (RAAS). Herein, angiotensin II (AngII) is a key mediator not only in blood pressure control and vascular tone regulation, but also involved in inflammation, endothelial dysfunction, atherosclerosis, hypertension and congestive heart failure. Since more than three decades suppression of AngII generation by inhibition of the angiotensin-converting enzyme (ACE) or blockade of the AngII-receptor has shown clinical benefit by reducing hypertension, atherosclerosis and other inflammation-associated cardiovascular diseases. Besides pharmaceutical ACE-inhibitors some natural peptides derived from food proteins reduce in vitro ACE activity. Several animal studies and a few human clinical trials have shown antihypertensive effects of such peptides, which might be attractive as food additives to prevent age-related RAAS activation. However, their inhibitory potency on in vitro ACE activity does not always correlate with an antihypertensive impact. While some peptides with high inhibitory activity on ACE-activity in vitro show no antihypertensive effect in vivo, other peptides with only a moderate ACE inhibitory activity in vitro cause such effects. The explanation for this conflicting phenomenon between inhibitory activity and antihypertensive effect remains unclear to date. This review shall critically address the effects of natural peptides derived from different food proteins on the cardiovascular system and the possible underlying mechanisms. A central aspect will be to point to conceptual gaps in the current understanding of the action of these peptides with respect to in vivo blood pressure lowering effects.

Abstract
Prehypertension (systolic blood pressure 120-139 or diastolic blood pressure 80-89 mm Hg) confers a risk of progression to hypertension, impairment of cognitive function, increased left ventricular mass, risk of end-stage renal disease, and an association with arteriosclerosis. Recent studies provide data that could support the rationale for treating prehypertensives subjects with antihypertensive medications in addition to lifestyle modification, especially if they have concomitant cardiovascular risk factors.
