NCT ID: NCT04749927 Recruiting - Clinical trials for Cardiovascular Disease

Deep Learning of Retinal Photographs and Atherosclerotic Cardiovascular Disease

Start date: October 11, 2020
Study type: Observational

The research team has developed a deep learning algorithm that predicts anthropometric factors from fundus photographs and an algorithm that predicts cardiovascular disease risk. Fundus photographs are taken for various cardiovascular diseases (myocardial infarction, heart failure, hypertension with target organ damage, high-risk dyslipidemia, diabetic patients, and low-risk hypertension patients), and a deep learning algorithm for predicting developed anthropometric factors will be validated. Fundus photographs will also be taken twice in the first year, and additional fundus photographs will be taken two years later. Major cardiovascular events will be followed up for 5 years to verify the deep learning algorithm predicting cardiovascular disease risk prospectively.

NCT ID: NCT04717336 Recruiting - Clinical trials for Cardiovascular Disease

Genomics, Environmental Factors and Social Determinants of Cardiovascular Disease in African Americans Study (GENE-FORECAST): Sodium Intervention Trial (SIT)

Start date: January 22, 2021
Phase: Early Phase 1
Study type: Interventional

Background: Hypertension is a risk factor for heart disease. Low-sodium diets rich in fruits, vegetables, and other healthy foods are a good way to reduce blood pressure in people with hypertension. Researchers want to learn more about why African Americans seem to have the greatest benefit from certain dietary interventions. Objective: To better understand the body s response to adding more salt to the diet. Eligibility: U.S.-born African American adults ages 21 to 65 who are in good general health and took part in the GENE-FORECAST. Design: Participants will be screened with a medical history and physical exam. If needed, they will take a pregnancy test. These tests will be repeated during the study. Each day for 2 weeks, participants will take 3 capsules that contain either placebo or salt. Then they will take no pills for 3 weeks. Then they will take placebo or salt capsules for 2 more weeks. Participants will talk about the foods and drinks they have consumed over the past 24 hours. They will take a survey about their physical activity and sleep. Participants will complete taste tasks to obtain their responses to sweetness or saltiness. Sucrose and salt detection thresholds and preferences will be assessed. Participants will give blood and urine samples. Saliva samples will be collected from their mouth by passive drool or by spitting into a sterile tube. Skin samples will be collected from behind their ears and the inner part of their elbow, using sterile swabs. Participants will get kits to collect stool samples at home. Participants will have 4 study visits over 7 weeks.

NCT ID: NCT04588727 Recruiting - Clinical trials for Cardiovascular Disease

Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Study of AZD3366 in Healthy Subjects

Start date: October 15, 2020
Phase: Phase 1
Study type: Interventional

Part A of this study is a Phase 1, First-in-human (FiH), randomized, single-blind, placebo controlled study to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD3366 following single intravenous (IV) ascending doses. Part B of this study is a randomized, single blind, parallel group placebo- controlled study to assess the safety, tolerability and PD of a single IV administration of AZD3366 with concomitant loading doses followed by repeated maintenance dosing of ticagrelor and acetylsalicylic acid (ASA).

NCT ID: NCT04568161 Recruiting - Breast Cancer Clinical Trials

Effect of Anthracyclines and Cyclophosphamide on Cardiovascular Responses

Start date: August 3, 2020
Phase: N/A
Study type: Interventional

The present study aims to investigate the chronic effect of treatment with doxorubicin and cyclophosphamide on neurovascular control and blood pressure in women undergoing adjuvant treatment for breast cancer.

NCT ID: NCT04545489 Recruiting - Hypertension Clinical Trials

A Nurse-led Intervention to Extend the Veteran HIV Treatment Cascade for Cardiovascular Disease Prevention

Start date: December 1, 2020
Phase: N/A
Study type: Interventional

The VA is the largest single provider of HIV care in the US and Veterans with HIV use significantly more healthcare services and have a 1.5-2x higher risk of atherosclerotic cardiovascular disease (ASCVD) compared to uninfected Veterans. The goal is to improve BP treatment for Veterans with HIV to reduce ASCVD risk. Within a RCT, the investigators hypothesize that the VA adapted nurse-led intervention will result in a clinically significant 6mmHg reduction in SBP over 12 months compared to those receiving enhanced education only. The study is innovative because of the use of stakeholder-engaged design process, multi-component nurse-led intervention, and VA Video Connect (VVC) to monitor CVD risk factors. The project meets VA strategic priorities including: 1) greater choice for Veterans; 2) improve timeliness of services; 3) focus more resources more efficiently (strengthen foundational services in VA). If shown to be effective, this intervention will have substantial impact among high-risk Veterans, potentially reducing ASCVD events by more than a quarter.

NCT ID: NCT04530825 Recruiting - Clinical trials for Cardiovascular Disease

PREVENT Tool Study: Late Effects Clinic

Start date: February 10, 2021
Phase: N/A
Study type: Interventional

The purpose of this study is to test the feasibility of a novel, Health Information Technology behavior change tool in a single clinic setting. The PREVENT tool is the first electronic health record (EHR)-compatible tool that both tailors evidence-based behavior change strategies and incorporates community-level data specific to each patient into routine care. The central hypothesis is that PREVENT will improve patient's attitudes towards behavior change recommendations, increase adherence to recommended behavior change and improve cardiovascular health. Fifty adolescents will be randomized to intervention or wait-list, routine care control to assess the preliminary effectiveness of PREVENT. Qualitative and quantitative methods will be used among patients, parents and providers to examine barriers to current and future implementation of the PREVENT tool to inform adoption and maintenance.

NCT ID: NCT04460131 Recruiting - Clinical trials for Cardiovascular Disease

Soluble ST2 and Cardiovascular Outcome

Start date: January 1, 2019
Study type: Observational

Cardiac surgery induces hemodynamic stress on the myocardium, and this process can be associated with significant cardiovascular morbidity and mortality. Soluble suppression of tumorigenicity 2 (sST2) is biomarker of myocardial remodeling and fibrosis; however, little is known regarding their potential association with cardiovascular events. This study aimed to investigate the release of sST2 and its association with cardiovascular events undergoing cardiac surgery.

NCT ID: NCT04450888 Recruiting - Stroke Clinical Trials

Effects of Message Framing and Time Discounting on Health Communication for Optimum Cardiovascular Disease and Stroke Prevention

Start date: July 1, 2020
Phase: N/A
Study type: Interventional

Effects of Message framing and Time discounting on heath communication for Optimum Cardiovascular disease and Stroke Prevention(EMT-OCSP)is a pragmatic, 2 × 2 factorial, randomized, controlled, observer blinded, multicenter trial with four parallel groups. It aims to determine if risk and intervention communication strategy(gain-framed versus loss-frame, long-term context versus short-term context and the potential interaction)have different effect on optimizing adherence to clinical preventive management (in the endpoint of CVD risk reduction)for subjects with at least one moldable risk factor for CVD.

NCT ID: NCT04310917 Recruiting - Clinical trials for Cardiovascular Disease

Clinico-biological Collection of Subjects With Hyper Lipoprotein a in Reunion Island

Start date: September 19, 2020
Phase: N/A
Study type: Interventional

Cardiovascular disease (CVD) is the second leading cause of death in France and the leading cause of death on Reunion Island. Some modifiable risk factors for cardiovascular diseases are well identified and can be easily modulated, in particular by hygiene and dietetic measures (tobacco, sedentary lifestyle). Other risk factors such as high blood pressure, diabetes or dyslipidemia can also be pharmacologically modulated. On the other hand, there is a cardiovascular risk factor that we do not know how to modulate: a high level of lipoprotein (a) (Lp (a)), whose regulation remains largely unknown. High plasma levels of Lipoprotein (a) remain a major risk for the development of cardiovascular disease and its clinical complications, which no drug can currently reduce. Understanding the biological and genetic determinants modulating Lp (a) levels remains a major challenge for treating subjects with hyper Lp (a). Several individuals and possibly Reunion families have been detected as having abnormally high rates of apo (a) Thanks to the link between cardiovascular clinical picture, Lp (a) concentration and other biological markers, the study should allow a better understanding of the mechanisms underlying the cardiovascular risk in order to offer advice. prevention and care of at-risk subjects screened; or even avenues for adapted genetic counseling (DNA sequencing). At the genetic level, several hypotheses could be explored making it possible to link the expression of the apo (a) protein to the genotype, in particular the presence of mutations in the gene, in the promoter region, polymorphisms, or epistatic regulation.
