Filter by:This study plans to learn more about differences in heart disease risk after gender-affirming orchiectomy (i.e., testes removal) in older transgender (trans) women compared to younger trans women.
This study intends to establish the normal reference values of carotid artery intima-media thickness and vascular elasticity of Chinese adults based on ultrasound radio frequency technology through a multi-center large-sample study, which provides important information for the risk prediction and prognosis evaluation of Chinese adults' cardiovascular disease.
Arterial disease is the leading cause of morbidity/mortality in Metabolic syndrome (MetS). This occurs early as evidenced by arterial dysfunction that, in turn, raises blood pressure and glucose. Health organizations recommend exercise in an intensity based manner to promote cardiovascular adaptation and prevent disease. Metformin is a common anti-diabetes medication that reduces future type 2 diabetes and cardiovascular risk. However, the optimal exercise dose to be combined with metformin for additive effects on vascular function is unknown. Based on the investigator's preliminary work, the overall hypothesis is that metformin blunts adaptation following high intensity exercise training (HiEx) by lowering mitochondrial derived oxidative stress signaling. The investigators further hypothesize that low intensity exercise (LoEx) training combined with metformin will promote additive effects on vascular function compared to LoEx or HiEx+metformin, and maintain/improve non-exercise physical activity patterns. In this double-blind trial, obese 30-60y MetS participants will be randomized to: 1) LoEx+placebo; 2) LoEx+metformin, 3) HiEx+placebo; or 4) HiEx+metformin for 16 weeks.
This study will examine the impact of cardiac rehabilitation on blood vessel health using a newly developed microfluidic-based tactile sensor to assess blood vessel health. The participants will have their blood vessel health measured using a sensor that is placed on top of the skin over the artery before and after exercise (1, 3, 5, 10, 30 and 60 mins). The investigators will study these responses at the first session of cardiac rehabilitation and following 1 and 4 weeks of cardiac rehabilitation (sessions 3 and 6). The investigators will also collect some information from the medical record regarding: age, gender, body mass index, resting cardiovascular measures (heart rate, blood pressure etc), medications, reasons which qualified the participant into cardiac rehabilitation, blood tests related to heart or cardiovascular function, metabolic panel, lipid panel, echocardiogram results, recorded electrocardiogram, known vascular diseases, presence of implantable devices, Seattle Heart Failure Model data and cardiovascular measures and exercise workloads during cardiac rehabilitation.
The aim of this study is to assess the effect of interval hypoxy-hyperoxic training (IHHT) on the arterial stiffness and elasticity of the liver tissue in patients with metabolic syndrome and on other components of the metabolic syndrome, and the possibility of their reversible recovery after training.
The objective of this study is to assess the effect Spinal Cord Stimulators have toward improving vascular changes of diabetes mellitus in patients eligible for SCS placement based on their condition of painful diabetic neuropathy; we will evaluate improving their disability and quality of life, improving micro-circulatory changes induced by Diabetes Mellitus (DM), improving macro-circulatory changes induced by DM and improving arterial stiffness of the vessels of the lower extremity.
In the United States, secondhand smoke is the third leading preventable cause of death. Flavored hookah (waterpipe) tobacco smoking, a highly social activity common in hookah bars, is a key source of SHS exposure. While smoke-free air laws have decreased exposure to secondhand smoke, the majority of laws do not include hookah smoking. Thus, as a social outlet for youth and young adults, hookah smoke exposure may harm non-smokers, including women of reproductive age or pregnant, hookah bar workers, children, and individuals with heart and lung disease. While more is known on the acute effects of active hookah smoking and the literature is emerging on active e-hookah vaping, little is known about the acute vascular effects of secondhand exposure to hookah smoke and aerosol. The study aims to examine the acute effects of secondhand exposure of hookah smoke and aerosol on endothelial and vascular function. Eligible volunteers will be invited to participate in a total of 3 study visits (2-3 hours each): e-hookah aerosol exposure, charcoal-heated hookah smoke exposure and smoke-free room air. Non-invasive blood pressure and blood flow measurements will be taken before and after the exposure sessions.
This is a single-center observational study on adolescents to determine predictors of the early steps of the formation of atherosclerosis and to quantify their influence on Intima-Media-Thickness of the carotid artery and the aorta and on the Pulse-Wave Velocity. A long-term follow-up by means of record linkage is furthermore planned to evaluate the effect of early atherosclerosis and the cardiovascular risk profile on future morbidity with a special focus cardio- and cerebrovascular events.
This observational study will evaluate the effect of puberty suppression on insulin sensitivity, metabolic rate and vascular health among transgender female youth at baseline and 6 months after initiation of a gondoatropin releasing hormone agonist compared to matched cisgender male controls.
The investigators aim to investigate the factors affecting cardiorespiratory fitness in individuals with systemic hypertension.
