How aortic stiffness in postmenopausal women is related to common cardiovascular risk factors

Association between sarcopenia and cardiovascular disease according to menopausal status: findings from the China Health and Retirement Longitudinal Study (CHARLS)

BACKGROUND

Little is known about the association between sarcopenia and cardiovascular disease (CVD) according to menopausal status, and we conducted cross-sectional as well as longitudinal analyses Using nationally representative data from the China Health and Retirement Longitudinal Study (CHARLS) to investigate the association between sarcopenia and CVD in Chinese women according to menopausal status.

METHOD

The study sample included 5365 (mean age 60.3 ± 9.3 years) female participants from CHARLS 2015 (wave 3). Additionally, 3,882 participants without cardiovascular disease (CVD) were recruited in CHARLS 2015 (Wave 3) and followed up in 2018 (Wave 4). CVD was defined as the presence of physician-diagnosed heart disease and/or stroke. Menopausal status was determined based on self-reported information from questionnaires. Sarcopenia status was assessed using the diagnostic criteria established by the Asian Working Group on Sarcopenia in 2019 (AWGS 2019). Binary logistic regression analyses were conducted to explore the association between sarcopenia and CVD in both premenopausal and postmenopausal women. Further analyses examined the interaction between sarcopenia and menopausal status to better understand its impact on CVD.

RESULTS

The prevalence of CVD in the total population is 22.5% (1209/5365). Among premenopausal women, the prevalence in no-sarcopenia, possible sarcopenia, and sarcopenia group are 11.3% (86/759), 16.2% (17/105), and 13.9% (5/36), respectively, for postmenopausal women, the prevalence are 19.2% (320/1668), 32.6% (520/1597), and 21.8% (261/1200). Both possible sarcopenia (OR = 1.58; 95% CI: 1.29-1.93) and sarcopenia (OR = 1.34; 95% CI: 1.05,1.72) are associated with CVD in the population of postmenopausal women. There was a significant positive interaction between menopause and sarcopenia on CVD, the RERI = 5.30 (95%CI: 4.63, 5.98), the SI = 2.44 (95%CI: 1.84, 3.63), and the multiplicative effect = 2.18 (95%CI: 1.70, 2.66). In the longitudinal analysis, 514 (13.2%) new cases of CVD were diagnosed. In premenopausal women, sarcopenia was significantly associated with the development of CVD (OR = 2.44, 95% CI: 1.3,4.59). In postmenopausal women, possible sarcopenia (OR = 1.45, 95% CI: 1.28, 1.65) and sarcopenia (OR = 1.42, 95% CI: 1.23, 1.65) were more likely to have new-onset CVD than the postmenopausal no-sarcopenia women.

CONCLUSIONS

Sarcopenia and cardiovascular disease (CVD) risk show significant variations in cross-sectional and longitudinal associations across different menopausal statuses, with higher risks in postmenopausal women. An interaction between menopausal status and sarcopenia on CVD risk was found.

Early Diagnosis of Subclinical Atherosclerosis in Asymptomatic Type 2 Diabetic Normotensive Menopausal Women: A Global Pulse Wave Velocity Study

Arterial stiffness serves as a cardiovascular disease marker, aiding in the early identification of high-risk patients. We aimed to evaluate the prevalence of arterial stiffness, measured by global pulse wave velocity (gPWV), among diabetic normotensive menopausal women (DPMW) and its correlation with levels of glycosylated hemoglobin (HbA1c). We recruited 641 consecutive DPMW diagnosed with type 2 diabetes over 5 years. The control group (CG) consisted of 300 normotensive, normoglycemic menopausal women. Normal gPWV was defined as a velocity ≤7.1 m/s. We enrolled 641 DPMW with a mean age of 57 ± 12 years. The CG comprised 300 normotensive, normoglycemic postmenopausal women with a mean age of 56 ± 4 years. Among DPMW, 29 (4.5%) exhibited increased gPWV compared with 4 (1.3%) in the CG (p < 0.01). Of the 225 (35.1%) DPMW with HbA1c > 7.5%, 23 (10.2%) had increased gPWV. In contrast, among the 416 (64.9%) DPMW with HbA1c < 7.5%, only 6 (1.4%) had increased gPWV (p < 0.0001). Electrocardiographic (ECG) abnormalities were detected in 208 (32.4%) DPMW, with 11 (5.3%) of them exhibiting increased gPWV (p = 0.6). There was a higher prevalence of increased gPWV in asymptomatic normotensive DPMW, with a significant association between increased gPWV and elevated HbA1c levels. However, there was no correlation between increased gPWV and abnormal ECG findings, despite ECG being the sole test recommended by current guidelines for all diabetic patients. Early detection of elevated HbA1c levels and increased gPWV may identify asymptomatic DPMW at higher cardiovascular risk, highlighting the inadequacy of a simple ECG in assessing cardiovascular risk in this population.

Relation between aortic elasticity parameters and SYNTAX score in postmenopausal diabetic women

BACKGROUND

Postmenopausal women are at increased risk of coronary artery disease (CAD). Diabetes Mellitus is a major risk factor for CAD. The stiffening of the aorta is associated with increased cardiovascular morbidity and mortality. We aimed to investigate the relation of aortic elasticity parameters to CAD severity assessed by SYNTAX score (SS) in diabetic postmenopausal women. The study prospectively included 200 consecutive diabetic postmenopausal women with CAD who underwent elective coronary angiography. Patients were classified into 3 groups based on SS, low-SS ≤ 22, intermediate-SS ≥ 23- ≤ 32, and high-SS ≥ 33. Echocardiographic aortic elasticity parameters, including aortic stiffness index (ASI), aortic strain (AS) (%) and aortic distensibility (AD) were obtained in all patients.

RESULTS

Patients in the high SS group were older age and had a higher aortic stiffness. After adjusting different co-variates AD, AS, and ASI could be used as independent predictors of high SS with the following P-values (0.019, 0.016 and 0.010) and cut-off values (2.5, 3.6 and 2.9), respectively.

CONCLUSIONS

In diabetic postmenopausal women, the simple echocardiography-derived aortic elasticity parameters might predict the severity and complexity of angiographic coronary lesions assessed by the SS.

Hypertension in Women

Hypertension is one of the main causes of morbidity and mortality in the human population. Nevertheless, the intricate network of pathophysiological mechanisms that lead to the development of hypertension in women still awaits to be fully understood. From young age to maturity and senescence, the female body transits through different stages, each of them characterized with specific physiological features and disposition to particular pathological conditions, and that is exactly what makes the understanding of the genesis and adequate treatment of hypertension in women so challenging. Clinical and experimental findings emphasize the role of sex hormones, autonomic nervous system, renin-angiotensin-aldosterone system and arterial stiffness in the development of chronically elevated blood pressure in females. The purpose of this review is to briefly summarize the knowledge of the mechanisms and treatment of hypertension in women.

Habitual Combined Exercise Protects against Age-Associated Decline in Vascular Function and Lipid Profiles in Elderly Postmenopausal Women

Postmenopausal status is associated with increased risks for cardiovascular diseases (CVD). This study investigated differences in vascular function, lipids, body composition, and physical fitness in elderly postmenopausal women active in combined resistance and aerobic exercise (CRAE) training for 1 year versus a sedentary cohort of similar-in-age counterparts. Elderly postmenopausal women performing habitual CRAE training for 1 year (age ~75 year; CRAE, n = 57) and elderly sedentary postmenopausal women (age ~78 year; SED, n = 44) were recruited. Arterial stiffness (brachial-to-ankle pulse-wave velocity, baPWV), blood pressure, blood lipids, anthropometrics, 2-min walking distance, and muscular strength were assessed for both groups. There were significant differences for baPWV, systolic blood pressure, low-density lipoprotein, and body fat percentage, which were significantly lower (p < 0.05) in CRAE vs. SED, and both 2 min walking distance and muscular strength were significantly greater (p < 0.05) in CRAE vs. SED. These results indicate that elderly postmenopausal women participating in habitual CRAE training may have better protection against risks for CVD and have better physical fitness compared to SED counterparts.

Left ventricular mass, geometry and function in diabetic patients affected by coronary artery disease

INTRODUCTION

Coronary artery disease (CAD) is quite common among diabetic patients, our study goal is to detect the prevalence of left ventricular (LV) adverse changes in geometry, mass and diastolic function on diabetic, but not hypertensive patients, with coronary artery disease(CAD) and LV ejection fraction(LVEF)>45%, actually unknown, because of current guidelines that do not include echocardiographic assessment for follow up of diabetic patients.

PATIENTS AND METHODS

665 consecutive diabetic patients (443 females, mean age 66±9years), performed a complete echocardiographic assessment according to current ASE echo-guidelines: diastolic dysfunction (DD), eccentric hypertrophy (EH), concentric hypertrophy (CH) and concentric remodeling (CR) of LV were reported. CAD was assessed only by reports of bypass surgery, angioplasty or patients hospitalized for acute myocardial infarction.

RESULTS

218 patients (32.8%) presented LV changes: LVDD 49 (7.4%), LVEH 68 (10.2%), LVDD and EH 46 (6.9%), LVDD and CH 36 (5.4%), LVDD and CR 19 (2.9%). 447 (67.2%) had no LV changes. 81 (12.1%) patients with CAD, presented: LVDD 17 (21%), LVEH 32 (39.5%), LVDD and EH 9 (11.1%), LVDD and CH 7 (8.6%), LVDD and CR 8 (9.9%), 8 (9.9%) had no LV adverse changes. There were among CAD patients, a significantly higher prevalence of LVDD (p<0.02), LV eccentric hypertrophy (EH) (p<0.05), DD and LVEH (p<0.04), DD and LV concentric hypertrophy(CH) (p<0.03) and DD and LV concentric remodeling (p<0.02), when compared with those patients without CAD.

CONCLUSION

CAD is related to all different patterns of LV adverse changes in mass, geometry and diastolic function, with a significantly higher prevalence in our population of diabetic patients with normal systolic function. These changes however remain unrecognized until they undergo to a conventional echocardiographic assessment. We support this tool need to be included into future guidelines concerning follow-up of diabetic patients.

Metabolic syndrome and its components in postmenopausal women living in southern Italy, Apulia region

OBJECTIVES

The goal of our study was to determine the prevalence of metabolic syndrome (MetS) and all its components, in a population of postmenopausal women aged over 45 years, consecutively accessed to our Heart Station, during 2014, for their first cardiac examination,furthermore to estimate their cardiovascular risk and the achievement of target blood values of main risk factors, according to current Guidelines.

METHODS

We screened 1257 postmenopausal women. MetS was assessed according to the National-Cholesterol-Education-Program-Adult-Treatment-Panel III definition. Cardiovascular risk was calculated by the Systematic Coronary Risk Evaluation (<65 years).

RESULTS

MetS was assessed on 834 women (66.4%). Prevalence of each component was: hypertension on 767 women (91.9%), central obesity 758 women (90.9%), low high-density lipoproteins cholesterol (HDLc) increased levels 612 women (73.3%), high triglyceride levels 428 women (51.3%), glucose levels higher than 110mg/dl or diabetes 404 women (48.5%). Cardiovascular risk was moderate until 65 years, but it increases after. Metabolic control in postmenopausal women was poor for glucose, only 82 women (9.8%) presented glucose levels lower than 110mg/dl, it was better for systolic blood pressure, that was normal in 564 women (67.6%) and worse for lipid levels.

CONCLUSION

The prevalence of metabolic syndrome in our population of postmenopausal women is high. Hypertension and central obesity are the more common components. The cardiovascular risk is moderate-high, the achievement of target values for glycemic and lipid levels is unsatisfactory, while systolic blood pressure is enough well controlled but however it is mandatory to improve this goal. An early MetS diagnosis and an early educational intervention are useful to decrease cardiovascular risk of postmenopausal women affected by metabolic syndrome.
