Abstract
Sit-stand maneuvers (SSM) have increasingly been used for baroreflex sensitivity (BRS) measurement in physiological research, but it remains unknown as to how many SSM need to be performed to measure BRS and assess its relation with cardiovascular disease (CVD) risk. Therefore, this study aimed to determine 1) the effect of the number of SSM repetitions on BRS and 2) the association between BRS and CVD risk factors. Data were collected from 174 individuals during 5 minutes of spontaneous rest and 5 minutes of repeated SSM at 0.05 Hz (i.e., 15 cycles of 10-second sit and 10-second stand). During SSM, BRS was calculated from the incremental cycles of 3, 6, 9, 12, and 15 SSM using transfer function analysis of heart rate (HR) and systolic blood pressure (SBP). General CVD risk factors, carotid arterial stiffness, and cardiorespiratory fitness were measured. In result, HR and SBP increased during SSM (p<0.05). The BRS remained at a similar level during the resting and SSM conditions, while the coherence function reached its peak after 3 cycles of SSM. BRS with ≥6 cycles of SSM was strongly correlated with age (r=-0.721 to -0.740), carotid distensibility (r=0.625 to 0.629), and cardiorespiratory fitness (r=0.333 to 0.351) (all p<0.001). Multiple regression analysis demonstrated that BRS with ≥6 cycles of SSM explained >60% of the variance in CVD risk factors. Therefore, our findings suggest that repeated SSM significantly strengthens the association between BRS and CVD risk factors. Particularly, BRS with ≥6 cycles of SSM is strongly associated with CVD risk.

Performance of Carotid Revascularization Procedures as Modified by Sex. Ann Vasc Surg 2021; 81:171-182. [PMID: 34752853 DOI: 10.1016/j.avsg.2021.08.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Revised: 08/27/2021] [Accepted: 08/31/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Current recommendations on carotid revascularization postulate that women have both increased perioperative risks, such as stroke and death, as well as reduced benefit from intervention. These recommendations do not include data on transcarotid artery revascularization (TCAR). This study strives to compare safety and benefits of TCAR, TFCAS (Transfemoral Carotid Artery Stenting), and CEA (Carotid Endarterectomy) with regard to patient sex. METHODS We performed retrospective analysis of the Society for Vascular Surgery (SVS) Vascular Quality Initiative (VQI) CEA and stenting registries, as well as TCAR Surveillance Project data. We compared outcomes after TCAR, TFCAS, and CEA based on sex. The primary outcome was the rate of in-hospital stroke or death. Secondary outcomes included in-hospital stroke, death, transient ischemic attack (TIA), myocardial infarction (MI), stroke/death/MI, stroke/TIA, and recurrent ipsilateral stroke and/or death at 1-year of follow-up. RESULTS A total of 75,538 patients were included, of which 28,960 (38.3%) were female and 46,578 (61.7%) were male. TFCAS females had more than 2 times higher odds of stroke/death (OR:2.85, 95%CI: 2.21-3.67, P < 0.001) and stroke/death/MI (OR:2.23, 95%CI:1.75-2.83, P < 0.001) when compared to CEA females. Odds of TIA were also higher in both TFCAS females (OR:2.01, 95%CI:1.19-3.42, P = 0.010) and TCAR females (OR:1.91, 95%CI:1.09-3.35, P = .023) when compared to CEA females. However, only TFCAS females experienced increased odds of stroke/TIA (OR:1.96, 95%CI:1.45-2.65, P < 0.001) when compared to CEA females. TFCAS males had almost twice the odds of stroke/death (OR:1.74, 95%CI:1.39-2.16, P < 0.001) and 44% higher odds of stroke/death/MI (OR:1.44, 95%CI:1.19-1.75, P < 0.001), and more than 3-times increased odds of death (OR:3.45, 95%CI:2.53-4.71, P < 0.001) when compared to CEA males. Odds of in-hospital stroke were comparable between TFCAS and CEA after adjusting for covariates. TCAR males have half the odds of MI when compared to CEA males (OR:0.52, 95%CI:0.34-0.80, P = 0.003). At 1-year TCAR had comparable risk of stroke/death while TFCAS had increased risk of stroke/death when compared to CEA among both males and females. CONCLUSION TCAR performed similarly to CEA in both sexes regardless of symptomatic status. Stroke/death and stroke/death/MI rates were similar in symptomatic and asymptomatic males and females treated by CEA or TCAR. The 1-year outcomes of TCAR were also comparable to CEA in both sexes. It seems that TCAR may be a safe alternative to CEA particularly in women when surgical risk prohibits CEA and while TFCAS is associated with substantial adverse outcomes.

Sex steroids and markers of micro- and macrovascular damage among women and men from the general population. Eur J Prev Cardiol 2021; 29:1322-1330. [PMID: 33580786 DOI: 10.1093/eurjpc/zwaa031] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 07/11/2020] [Accepted: 07/27/2020] [Indexed: 12/18/2022]
Abstract
AIMS The contribution of sex hormones to micro- and macrovascular damage might differ among women and men. In particular, little is known about the association between sex hormones and small vessel disease. Therefore, we examined the association of total oestradiol, total testosterone, free-androgen index (FAI), dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione levels with micro- and macrovascular diseases. METHODS AND RESULTS This cross-sectional study included 2950 women and 2495 men from the population-based Rotterdam Study. As proxy of microvascular damage, we measured diameters of retinal arterioles and venules. Markers of macrovascular damage included carotid intima-media thickness and carotid plaque, coronary artery calcification (CAC), and peripheral artery disease. Linear and logistic regression models were used and adjusted for age, cardiovascular risk factors, and years since menopause. Associations with microvasculature: In women, total testosterone [mean difference per 1-unit increase in natural-log transformed total testosterone (95% confidence interval, CI): 2.59 (0.08-5.09)] and androstenedione [4.88 (1.82-7.95)] and in men DHEAS [2.80 (0.23-5.37)] and androstenedione [5.83 (2.19-9.46)] were associated with larger venular caliber. Associations with markers of large vessel disease: In women, higher total testosterone [-0.29 (-0.56 to -0.03)], FAI [-0.33 (-0.56 to -0.10)], and androstenedione levels [-0.33 (-0.64 to -0.02)] were associated with lower CAC burden and FAI [odds ratio (95% CI): 0.82 (0.71-0.94)] was associated with lower prevalence of plaque. CONCLUSION A more androgenic profile was associated with more microvascular damage in both women and men. Among women, however, higher androgen levels were also associated with less macrovascular damage. Our findings suggest that androgens might have distinct effects on the vasculature, depending on the vascular bed and stages of the atherosclerosis process.

Abstract
OBJECTIVE : An exaggerated exercise SBP, which is potentially modifiable, may be associated with incident depressive symptoms via an increased pulsatile pressure load on the brain. However, the association between exaggerated exercise SBP and incident depressive symptoms is unknown. Therefore, we examined whether exaggerated exercise SBP is associated with a higher risk of depressive symptoms over time. METHODS : We used longitudinal data from the population-based Maastricht Study, with only individuals free of depressive symptoms at baseline included (n = 2121; 51.3% men; age 59.5 ± 8.5 years). Exercise SBP was measured at baseline with a submaximal exercise cycle test. We calculated a composite score of exercise SBP based on four standardized exercise SBP measures: SBP at moderate workload, SBP at peak exercise, SBP change per minute during exercise and SBP 4 min after exercise. Clinically relevant depressive symptoms were determined annually at follow-up and defined as a Patient Health Questionnaire score of at least 10. RESULTS : After a mean follow-up of 3.9 years, 175 participants (8.3%) had incident clinically relevant depressive symptoms. A 1 SD higher exercise SBP composite score was associated with a higher incidence of clinically relevant depressive symptoms [hazard ratio: 1.27 (95% confidence interval: 1.04-1.54)]. Results were adjusted for age, sex, education level, glucose metabolism status, lifestyle, cardiovascular risk factors, resting SBP and cardiorespiratory fitness. CONCLUSION : A higher exercise SBP response is associated with a higher incidence of clinically relevant depressive symptoms.

Dehydroepiandrosterone and age-related musculoskeletal diseases: Connections and therapeutic implications. Ageing Res Rev 2020; 62:101132. [PMID: 32711158 DOI: 10.1016/j.arr.2020.101132] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 06/01/2020] [Accepted: 07/18/2020] [Indexed: 12/12/2022]
Abstract
Musculoskeletal disorders related to ageing are one of the most common causes of mortality and morbidity among elderly individuals worldwide. The typical constitutive components of the musculoskeletal system, including bone, muscle, and joints, gradually undergo a process of tissue loss and degeneration as a result of life-long mechanical and biological stress, ultimately leading to the onset of a series of age-related musculoskeletal diseases, including osteoporosis (OP), sarcopenia, and osteoarthritis (OA). Dehydroepiandrosterone (DHEA), a precursor of androgen secreted mainly by the adrenal gland, has attracted much attention as a marker for senescence due to its unique age-related changes. This pre-hormone has been publicly regarded as an "antidote for ageing" because of its favourable effect against a wide range of age-related diseases, such as Alzheimer disease, cardiovascular diseases, immunosenescence and skin senescence, though its effect on age-related musculoskeletal diseases has been explored to a lesser extent. In the present review, we summarized the action of DHEA against OP, sarcopenia and OA. Extensive detailed descriptions of the pathogenesis of each of these musculoskeletal disorders are beyond the scope of this review; instead, we aim to highlight the association of changes in DHEA with the processes of OP, sarcopenia and OA. A special focus will also be placed on the overlapping pathogeneses among these three diseases, and the molecular mechanisms underlying the action of DHEA against these diseases are discussed or postulated.

The effect of different estradiol levels on carotid artery distensibility during a long agonist IVF protocol. Reprod Biol Endocrinol 2020; 18:44. [PMID: 32398163 PMCID: PMC7216631 DOI: 10.1186/s12958-020-00608-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Accepted: 05/03/2020] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND This study was made to figure out, does low and high estradiol levels during in vitro fertilization (IVF) cycles have a different effect on carotid artery distensibility (Cdis), carotid artery diameter (Cdia), blood pressure and metabolic factors? Can the stimulation protocol be considered safe to women's vasculature? METHODS We studied 28 women having a long agonist protocol IVF-treatment in Kuopio University Hospital during the years 2011-2016. Patients were examined at three time points: in the beginning of their own period (low estradiol), during the gonadotrophin releasing hormone (GnRH) analogue downregulation (low estradiol) and during the follicle stimulating hormone (FSH) stimulation (high estradiol). Women served as their own controls and their menstrual phase (2- to 5-day period after the beginning of menstruation with low estrogen) was used as the reference. Cdis and Cdia were assessed using ultrasound. Blood pressure, weight, estradiol levels and lipids were monitored. RESULTS Cdis, Cdia, systolic and diastolic blood pressures peaked during the GnRH-analogue treatment with the lowest estradiol levels. Cdis, Cdia and systolic blood pressures declined by 11% (P = 0.002), 3,8% (P < 0.001) and 2,5% (P = 0.026) during the FSH-stimulation when the estradiol levels were high. Cdis correlated significantly (P < 0.05) with systolic blood pressure, diastolic blood pressure and triglycerides in high estrogenic environment and with diastolic blood pressure (P < 0.05) when estrogen profiles were low. CONCLUSIONS Carotid artery stiffens during the high estradiol levels compared to low levels and this was not explained by the higher diameter of the carotid artery, hyperlipidemia or blood pressure profiles. All the changes in Cdis and Cdia are variations of normal, and if there is no history of cardiovascular problems, it can be considered, that the stimulation protocol is not hazardous to vasculature.

Sex differences in the circulatory responses to an isocapnic cold pressor test. Exp Physiol 2018; 104:295-305.

Abstract
NEW FINDINGS What is the central question of this study? Do sex differences exist in the cardiorespiratory responses to an isocapnic cold pressor test (CPT)? What is the main finding and its importance? During the CPT, there were no sex differences in the respiratory response; however, females demonstrated a reduced mean arterial pressure and reduced dilatation of the common carotid artery. Given that the CPT is predictive of future cardiovascular events, these data have clinical implications for improving the utility of the CPT to determine cardiovascular health risk. Sex differences should be taken into consideration when conducting and interpreting a CPT. ABSTRACT The cold pressor test (CPT) elicits a transient increase in sympathetic nervous activity, minute ventilation ( <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub><mml:mover><mml:mi>V</mml:mi> <mml:mo>̇</mml:mo></mml:mover> <mml:mi>E</mml:mi></mml:msub> </mml:math> ), mean arterial pressure (MAP) and common carotid artery (CCA) diameter in healthy individuals. Although the extent of dilatation of the CCA in response to the CPT has been used as a clinical indicator of cardiovascular health status, the potential sex differences have yet to be explored. In response to a CPT, we hypothesized that elevations in <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub><mml:mover><mml:mi>V</mml:mi> <mml:mo>̇</mml:mo></mml:mover> <mml:mi>E</mml:mi></mml:msub> </mml:math> and MAP and dilatation of the CCA would be attenuated in females compared with males. In 20 young, healthy participants (10 females), we measured the respiratory, cardiovascular and CCA responses during a CPT, which consisted of a 3 min immersion of the right foot into 0-1 ice water. Blood pressure (via finger photoplethysmography), heart rate (via electrocardiogram) and CCA diameter and velocity (via Duplex ultrasound) were simultaneously recorded immediately before and during the CPT. During the CPT, while controlling end-tidal gases to baseline values, the main findings were as follows: (i) no sex differences were present in absolute or relative changes in <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msub><mml:mover><mml:mi>V</mml:mi> <mml:mo>̇</mml:mo></mml:mover> <mml:mi>E</mml:mi></mml:msub> </mml:math> (P = 0.801 and P = 0.179, respectively); (ii) the relative MAP and CCA diameter response were reduced in females by 51 and 55%, respectively (P = 0.008 and P = 0.029 versus males, respectively); and (iii) the relative MAP responses was positively correlated with the dilatation of the CCA in males (r = 0.42, P = 0.019), in females (r = 0.43, P = 0.019) and in males and females combined (r = 0.55, P < 0.001). Given that the CPT is used as a clinical tool to assess cardiovascular health status, sex differences should be considered in future studies.

Abstract
The menopause transition (MT) is a critical period of women's lives marked by several physiologic changes and menopause-related symptoms that have implications for health. Risk for cardiovascular disease, the leading cause of death in women, increases after menopause, suggesting a contribution of the MT to its development. This article focuses on the relationship between 2 main features of the MT and women's cardiovascular health: (1) dynamic alterations of sex hormones, particularly endogenous estradiol and follicle-stimulating hormone, and (2) vasomotor symptoms, the cardinal symptom of the menopause. Limitations and future directions are discussed.

Abstract
BACKGROUND Women experience a steeper decline in aortic elasticity related to aging compared to men. We examined whether sex hormone levels were associated with ascending aortic distensibility (AAD) in the Multi-Ethnic Study of Atherosclerosis. METHODS We studied 1,345 postmenopausal women and 1,532 men aged 45-84 years, who had serum sex hormone levels, AAD measured by phase-contrast cardiac magnetic resonance imaging, and ejection fraction>50% at baseline. Among these participants, 457 women and 548 men returned for follow-up magnetic resonance imaging 10-years later. Stratified by sex, and using mixed effects linear regression methods, we examined associations of sex hormones (as tertiles) with baseline and annual change in log-transformed AAD (mm Hg-110-3), adjusting for demographics, body size, lifestyle factors, mean arterial pressure, heart rate, hypertensive medication use (and in women, for hormone therapy use and years since menopause). RESULTS The mean (SD) age was 65 (9) for women and 62 (10) years for men. AAD was lower in women than men (P < 0.001). In adjusted cross-sectional analysis, the highest tertile of free testosterone (compared to lowest) in women was significantly associated with lower AAD [-0.10 (-0.19, -0.01)] and the highest tertile of estradiol in men was associated with greater AAD [0.12 (0.04, 0.20)]. There were no associations of sex hormones with change in AAD over 10 years, albeit in a smaller sample size. CONCLUSIONS Lower free testosterone in women and higher estradiol in men were associated with greater aortic distensibility at baseline, but not longitudinally. Sex hormone levels may account for differences in AAD between women and men.

Abstract
Cardiovascular disease is the leading cause of death in both women and men. Its pathogenesis is multifactorial, with sex hormones playing an important role. Androgens have both direct and indirect effects on the vasculature. This review summarizes evidence on the association of both endogenous and exogenous androgens with subclinical and overt cardiovascular disease in women and men. Concerning women, both high and low levels of endogenous androgens have been associated with cardiovascular disease, while other studies have reported no association. Adiposity, impaired glucose metabolism, dyslipidemia and estrogen levels may mediate the observed associations. Regarding testosterone therapy in women, there have been no large prospective studies on cardiovascular outcomes. Concerning men, most studies indicate that low levels of circulating testosterone are associated with increased rates of cardiovascular disease in the general population; the causality, however, of this association remains to be proven. Testosterone replacement therapy in men with symptoms of hypogonadism and low serum testosterone merits caution with regard to cardiovascular safety, as evidence is still conflicting.

Abstract
OPINION STATEMENT Prostate cancer is a common hormone-sensitive malignancy, and androgen deprivation therapy (ADT) is a cornerstone of therapy in advanced disease. The most important and controversial of ADT side effects is cardiovascular (CV) toxicity. Prospective trials have demonstrated that ADT increases CV risk by lowering insulin sensitivity, causing dyslipidemia, and causing weight gain thus mimicking metabolic syndrome. Retrospective data suggests that ADT increases CV risk; however, data on cardiovascular mortality is equivocal. This discrepancy can be explained by study design limitations and selection bias inherent to post hoc analysis of trials not designed to study CV outcomes. Despite the adverse CV and metabolic sequelae of ADT, little data is available for optimal cardiac screening or management in these patients. The short-term CV risk is higher in patients who have had CV events in the year prior to starting ADT. A careful discussion of risk and benefit of ADT must take place with patients with pre-existing CV disease prior to initiating hormonal therapy. The duration of ADT must be considered. We recommend diligent pretherapy screening and optimization of cardiac risk factors and close surveillance especially within the first year of ADT.

Abstract
OBJECTIVE To explore the preventive effect of aspirin on the cardiovascular complications in prostate cancer after endocrinotherapy. MATERIALS AND METHODS A total of 92 patients with prostate cancer were divided into observation group (n=44) and control group (n=48). The control group was treated with medical castration plus anti-androgenic drugs. Based on the above treatment, the observation group was added aspirin. The follow-up duration was 2 years. The changes of partial prothrombin time (PT), activated partial thromboplastin time (APTT), platelet aggregation rate (PAG), prostate-specific antigen (PSA) and serum testosterone (T) before and after treatment as well as incidence of cardiovascular disease were observed. RESULTS The 2-year survival rates of patients without cardiovascular disease in observation group and control group were 95.45% (42/44) and 72.92% (35/48), respectively, and significant difference was presented between two groups by comparison to the survival rates (χ2=8.5453, p=0.0035). There was no statistical significance between two groups as well as before and after treatment regarding PT (p>0.05). After treatment, APTT went down and PAG was gradually on the rise in control group, while PAG down and APTT on the rise increasingly in observation group. Significant differences were presented between two groups as well as before and after treatment (p<0.01). Both PSA and T levels were decreased significantly in two groups after treatment (p<0.01), but there was no statistical significant between two groups (p>0.05). CONCLUSIONS Application of endocrinotherapy in prostate cancer can easily lead to occurrence of cardiovascular disease, but cardiovascular complications can be prevented by aspirin, without affecting the effect of endocrinotherapy.
