Cardiovascular Diseases Clinical Trials

Treatment strategies for cardiac surgery patients have been evolving significantly for the last decade. While clinical outcomes have been improving, there are still significant areas unexplored in these patients. Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons. It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, and atherosclerosis. Biobanking is a fundamental process required in the better understanding of human diseases together with their underlying mechanisms. Biobanking refers to the process by which samples of bodily fluid or tissue are collected for research use to improve the understanding of health and disease. For this study, the investigator's objective is to acquire elucidation in disease etiology, translation, and advancing public health by evaluating blood and tissue results of those with cardiac disease undergoing cardiac surgery.

This randomized controlled trial will evaluate whether use of the PulsePoint system increases bystander CPR or defibrillator use compared to standard dispatch procedures in patients who suffer non-traumatic, out-of-hospital cardiac arrest in a public location. Half of all suspected cardiac arrest 9-1-1 calls in a public location will receive PulsePoint alerts (treatment arm). The other half of this eligible patient cohort will receive standard dispatch procedures (control arm). Read Less

The purpose of this clinical study is to compare how well two different devices for achieving hemostasis perform in patients undergoing transfemoral procedures with 6 French Access. Both devices are approved by the FDA for this use, and have already been used by clinicians on patients undergoing transfemoral procedures. It is believed that the use of both devices in combination compared to the Perclose alone will shorten the time that it takes to 'seal' the artery, resulting in a shorter period of time that patients would need to lay flat.

Cardiac rehabilitation (CR) is a secondary prevention program for patients with cardiovascular disease (CVD). It is especially valuable as CVD increasingly occurs in combination with comorbidity, frailty, and complexities of care that predispose patients to functional decline, disability, and high costs. Still, few Veterans participate in CR, in part because of the difficult logistics to attend. Promising Practice home-based CR (HBCR) was developed to increase CR participation, but many Veterans remain too limited by comorbidity and frailty for participation. A Transition to CR (T2CR) intervention is a face-to-face program that fosters vital skills, education, insights, motivation, and patient-provider relationships conducive to successful HBCR thereafter. This study compares Veterans eligible for CR who are randomized to T2CR intervention versus usual care. Differences in functional capacity, HBCR participation, and healthy days at home are compared over one year. Patients' experiences and providers' perspectives of barriers and facilitators to T2CR are also compared. Read Less

This is a study of biomarkers obtained from prospectively collected subject samples and their correlation with cardiovascular and metabolic diseases. The purpose of this initiative is to develop an enduring tool to allow for collaborative research between clinicians at Cleveland Clinic Main Campus and basic scientists at the Lerner Research Institute. This collaboration will allow resources to be available to clinical and basic researchers alike. This tool will enable research of vascular disease in the Vascular Lab and will leverage this valuable asset to the fullest extent to allow for interdepartmental collaboration. Read Less

This study is a randomized, factorial experiment using the basic Science of Behavior Change (SOBC) approach to efficiently test the effects of four distinct behavior change techniques (BCTs), goal setting, action planning, self- monitoring and feedback, thought to engage one key behavioral mechanism of action (MoA) for improving daily walking by at least 1000 steps per day in persons who have been objectively verified as sedentary and are at risk for cardiovascular disease.

Metabolic surgery is an emerging option to treat obesity-related metabolic diseases (e.g., type 2 diabetes) and prevent cardiovascular disease (CVD). Metabolic surgery can profoundly alter the gut microbiota; meanwhile, gut microbiota may affect surgical outcomes. Longitudinal studies that examined pre- to post-surgery changes in gut microbiota and its relation to cardiometabolic health after surgery are limited. Furthermore, few studies have included African Americans, a population with high rates of cardiometabolic diseases. The investigators aim to fill these research gaps by establishing a longitudinal, observational study of metabolic surgery patients and applying multi-omics to identify stool, blood, and/or tissue microbial features related to post-surgery cardiometabolic outcomes. In the current study, the investigators plan to enroll up to 300 patients who undergo metabolic surgery at Vanderbilt University Medical Center and follow them for up to 10 years after surgery. Fasting blood and stool samples will be collected at pre-surgery and 3-month, 1-year, 2-year, and 3-year post-surgery clinical visits. Tissue samples (e.g., biopsies of the liver and adipose and remnants of the stomach) will be collected during operation. Meanwhile, participants will complete a REDCap survey at baseline and 1-year, 2-year, and 3-year post-surgery. Participants' electronic medical records will be used to obtain additional information and facilitate long-term follow-up. The investigators will evaluate pre- to post-surgery changes in the fecal microbiome and fecal and blood levels of metabolites and proteins and the associations of microbiome, metabolites, and proteins with cardiometabolic improvements after surgery. This study will advance our understanding of the role of gut microbiota in metabolic surgery, which may translate into novel approaches to identify and treat obese patients for better cardiometabolic health.

The purpose of this study is to demonstrate whether Behavioral Activation for depression delivered via home based telehealth (BA-HT) is effective in improving social and role functioning in Veterans recently discharged from Cardiovascular disease (CVD-related) inpatient care. Eligible participants will receive either (1) twelve sessions of BA-HT or (2) standard best practices post CVD hospitalization care. Study participants will be 132 Veterans discharged from the Ralph H. Johnson VA Medical Center inpatient care facilities with CVD diagnoses corresponding to ICD 10 codes I20-I25 (120 unstable angina, stable angina; 121 NSTEMI, STEMI, initial encounter; 122 NSTEMI, STEMI, subsequent encounter; 124 acute coronary syndrome; 125 coronary arteriosclerosis with angina). They will be male or female, age 21 and above, and with approximately 40-50% minority representation. There will be assessment at baseline, 1 week post treatment, as well as 3 and 9-months post treatment. The investigators predict that BA-HT will more effectively increase social role and activity functioning, activity, mood and reduce 9-month re-hospitalization compared to current best-practices post-discharge care among patients scoring at least moderately depressed on the PROMIS Depression scale one week following hospital discharge for a CVD event.
