Filter by:The largest epidemiologic study of Hispanic/Latino participants thus far, i.e., the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) documented that 80% of men and 71% of women have at least one major cardiovascular disease (CVD) risk factor. The American Heart Association emphasizes that current CVD prevention efforts are sparse and ineffectual in minority populations and acknowledges the need for new and more effective disease prevention strategies. This observational study and pilot cluster-randomized clinical trial seeks to implement and evaluate a novel 8-week Positive Psychology (PP) Intervention (compared to an attention control condition) in Hispanic/Latino adults with uncontrolled hypertension, i.e., elevated 24-hour ambulatory blood pressure, with primary interest in testing efficacy for clinically meaningful improvements in cardiovascular function.
Ischemic Heart Disease (IHD) is a condition of recurring chest pain or discomfort that occurs when a part of the heart is not receiving sufficient blood flow. It is a major public health concern internationally and in Singapore, the leading cause of death from cardiovascular disease. Cardiovascular magnetic resonance (CMR) has the ability to assess heart structures, scarring or lack of blood supply to the heart muscle with great accuracy and without any radiation involved. A CMR-compatible cycle ergometer can offer a safe and low cost stress equipment to assess heart function and motion abnormalities, and restrictions of the blood supply to the heart tissues due to partial or complete blockages of the blood vessels. This study aims 1. to develop an exercise-CMR stress protocol by testing its feasibility and robustness in assessing changes in cardiac volumes and function due to physical exertion in healthy individuals and 2. to assess the accuracy of the multiparametric stress-CMR as a diagnostic tool for ischemic-causing coronary artery disease (CAD) with coronary fractional flow reserve (FFR) as a reference. 3. to measure the overall economic impact of ischaemic heart disease by estimating the direct and indirect medical costs for each participant. The current sample costs will be extrapolated to estimate the annual costs of treating and managing ischaemic heart disease in the local population. 4. to evaluate the effects of coronary microvascular dysfunction on coronary flow and regulation, physiological response and cardiac sympathetic signaling in patients with chest pain.
In the proposed method of sensing the vital health sign related to cardiovascular diseases, thermal heat transfer performance of the skin will be evaluated using a non-contact based Infra-Red temperature sensor. The temperature of the skin is significantly dependent upon the heat source as blood vessels (veins and capillaries) in the vicinity of the skin. However, there are several locations in the human body, where arteries are also at a relatively less depth from the outer skin surface (radial or ulnar arteries at the wrist and carotid artery in the neck). If it is possible to track the flow of blood from the thermal performance of the skin, then it could be useful in predicting various states of the human health related to cardiovascular activities. Subjects will undergo Existing Procedure EP- Passive Thermography PT for Phase I and Existing Procedure EP- Active Thermography ATLIC/ATPC for Phase II, with Duplex Ultrasound being the existing procedure that is considered as more reliable in clinical practice. Existing Passive Thermography will be used to setup the baseline data for Phase I. The currently under-development temperature mapping method (Active Thermography) that involves application of cooling (either pulsed or lock-in cooling) over the skin will be utilized for Phase II.
This study will test whether a digital health intervention (DASH Cloud) using smartphones can improve diet quality among women at risk for cardiovascular disease. The DASH (Dietary Approaches to Stop Hypertension) Diet has been proven to lower blood pressure, yet dissemination efforts remain poor. This study aims to use technology to improve adherence to DASH.
This study plans to learn more about how to increase postpartum weight loss and how to decrease risk factors for postpartum women at increased risk for diabetes and heart disease. The program is delivered using a mobile application (app) and a lifestyle coach. This mobile application is developed for women who are at higher risk for diabetes and heart disease. Women who have gestational diabetes, (diabetes during pregnancy, or GDM), gestational hypertension (high blood pressure), and/or preeclampsia (high blood pressure and protein in the urine), and/or small-for gestational-age, and/or preterm (early) delivery during their pregnancies have a higher risk for diabetes and heart disease. This mobile application was developed using the latest research studies and using the evidence-based Diabetes Prevention and Colorado Weigh programs. The goal of the program is to help women lose weight and participate in physical activity after delivery.
This study intends to investigate the relevant risk factors of perioperation complications or mortality in older patients with cardiac diseases undergoing teeth extraction surgery and this study aims to quantify the risk factors and then to establish the predictive scoring systems. Hypothesis:Preoperative parameters could predict postoperative complications.
Continued uncertainty exists over benefits of early intensive blood pressure (BP) lowering in acute intracerebral hemorrhage (ICH), related to the non-significant primary outcomes, patient selection, and discordant results of INTERACT2 and ATACH-II. We designed INTERACT3 to determine the effectiveness of a goal-directed care bundle of active management (intensive BP lowering, glycemic control, treatment of pyrexia and reversal of anticoagulation) vs. usual care in ICH. INTERACT3 is a large-scale pragmatic clinical trial to provide reliable evidence over the effectiveness of a widely applicable goal-directed care bundle in acute ICH.
Atherosclerosis in the setting of HIV infection is distinct and includes increased vascular inflammation, worsened endothelial function, and a predominance of non-calcified plaque. These outcomes can be assessed using specialized noninvasive imaging which strongly predict future CV events in the general population. PCSK9 has emerged as an important pharmacologic target for cholesterol lowering in the general population and recent studies among individuals without HIV have shown that PCSK9 inhibitor therapy is safely tolerated and significantly reduces major CV events in the general population. The investigators will perform a clinical trial of PCSK9 inhibition in the setting of HIV infection. This will be a randomized, placebo-controlled study to evaluate the effects of PCSK9 inhibition on vascular inflammation, endothelial function, and non-calcified plaque using a PCSK9 inhibitor called alirocumab. This study will recruit 140 treated individuals with HIV who are aged 40 and older, with known CVD or risk factors for CVD and who have evidence of vascular inflammation at baseline. The primary and secondary objective of this study is to determine whether PCSK9 inhibition can improve arterial inflammation as assessed by FDG-PET/CT and endothelial function as assessed by flow mediated vasodilation. The investigators will correlate changes in arterial inflammation and endothelial function with lipids and markers of inflammation and immune activation. The tertiary objective is to perform a pilot evaluation of the impact of PCSK9 inhibition on non-calcified plaque as measured by coronary CT angiography. Non-calcified plaque measurements will be correlated with changes in lipid parameters and markers of inflammation and immune activation.
The aim of the BRAGATSTON study is to provide a low cost tool for measuring CAC in breast cancer patients, thereby identifying patients at increased risk of CVD. Breast cancer patients and doctors can act upon this, by adapting the treatment and/or by adopting cardioprotective interventions. Hereby, the burden of CVD in breast cancer survivors can be reduced and better overall survival rates can be achieved.
The purpose of this research study is to design, implement, and evaluate a community level, socio-ecological based CVD prevention intervention using a participatory approach for women in a homogeneous ultra-Orthodox Jewish Hasidic community in Israel. A quasi-experimental, pre-post study design will be utilized, where all community participants will be exposed to intervention components. Pre and post samples will be selected through randomized cluster sampling of pre-existing community groups. It is hypothesized that ultra-Orthodox Jewish Hasidic women exposed to this community intervention will have improved healthy eating behaviors, reduced unhealthy eating behaviors, increased engagement in physical activity and sleep, and reduced risk for obesity (weight, BMI).
