NCT00829660
The purpose of this study is to determine whether acarbose therapy can reduce cardiovascular-related morbidity and mortality in patients with impaired glucose tolerance (IGT) who have established coronary heart disease (CHD) or acute coronary syndrome (ACS). A secondary objective of the study is to determine if acarbose therapy can prevent or delay transition to type 2 diabetes mellitus (T2DM) in this patient population.
NCT01501981
In this pilot, investigator-initiated multi-centre, multinational, observational study the investigators would like to examine the impact of therapy optimization on the level of biomarkers in patients with acute decompensated and decompensated chronic heart failure. The primary objective is to determine the best time point for measuring biomarker levels during therapy optimization in patients with decompensation to predict clinical outcomes such as mortality, hospitalisation, and quality of life. Secondary objectives are: 1. To evaluate the impact of guideline-recommended medication on biomarker levels during and following recompensation. 2. To evaluate whether the trajectory of relevant biomarkers (MR-proANP, MR-proADM) is of relevance to guide medical therapy following decompensation. 3. To evaluate whether the degree of biomarker change (e.g. slow versus rapid change) is of relevance with regard to hemodynamic stability and cardiovascular events such as hospitalisation. 4. To evaluate whether the trajectory of relevant biomarkers (copeptin, CT-pro-ET1) is of relevance to guide medical therapy following decompensation.
NCT02409225
Purpose: Home monitoring (HM) services supplied by different manufacturers (St Jude Medical, Biotronik, Medtronic) enables trained medical staff (doctors, electrophysiology nurses and technicians) to safely follow-up patients with implanted ICD/CRT-D remotely, with omitting unnecessary visits in outpatient clinic, shortening time to medical intervention and therefore help to decrease hospitalization rate among those patients. The RESULT study primary endpoint of the trial will be a composite of all-cause death or hospitalization due to cardiovascular reasons. The primary technical endpoint is to construct and evaluate a unified and integrated platform for data collected from RM devices manufactured by different companies: Carelink™ (Medtronic®, Minneapolis, MN, USA), Merlin™ (Saint Jude Medical®, St. Paul, MN, USA) and Home Monitoring™ (Biotronik®, Berlin, Germany).

NCT03227497
This cross-over study investigates health effects of dietary intake of whole walnuts towards cardiovascular risk factors in adults under low cardiovascular risk. Investigators hypothesize that daily intake of whole nuts as a replacement meal, would improve cardiovascular risk factors, including traditional risk factors and molecular biomarkers. The participants are randomly assigned to receive either study treatment, or no treatment, and are crossed after five weeks. The study subjects are instructed to continue with their habitual diet and physical activity.
NCT01853332

Is treatment effective in improving the disease pathology of patients with Heart Disease as assessed by a series of measurements indicating improvement, stability, or degradation of a patient's cardiovascular function and exercise capacity?
NCT02022046
Chronic kidney disease (CKD) and end-stage renal disease are highly prevalent in Taiwan. Cardiovascular disease (CVD) is the most common cause of death in children with CKD. Nitric oxide (NO) deficiency links CKD and CVD. Asymmetric dimethylarginine (ADMA), a NO synthase inhibitor, its level is increased in kidney disease and cardiovascular disease and serves as a methylation biomarker. In addition to ADMA, uremic environment, hyperhomocysteinemia (Hcy) and oxidative stress may affect DNA methylation. S-adenosylmethionine (SAM) is an important human methyl donor. S-adenosylhomocysteine (SAH) is demethylated product. Methylenetetrahydrofolate reductase (MTHFR), a folate metabolism enzyme can regulate methylation pathway. The investigators intend to examine whether ADMA, SAM/SAH ratio, Hcy, and MTHFR gene methylation can serve as biosignature to predict CVD in children with CKD children.
NCT01350791
This study is a non-randomized, prospective, open-label registry to compare the efficacy and safety of Promus Element stents versus first-generation drug-eluting stent (DES) in patients with coronary artery disease.
NCT00948714
Project Overview: Poor hypertension control has dire consequences for the African-American population who suffer greater death and disability from heart disease, stroke, and renal failure than whites. To reduce these health disparities it is critical to promote of a healthy lifestyle in regard to diet, exercise, adherence to medications, as well as other behaviors. However, physicians usually fail to address lifestyle behaviors in the context of the harried patient visit. Therefore, the investigators hypothesized that the investigators could reduce cardiovascular risk by providing additional support to persons with poorly controlled hypertension through phone calls from trained peer patients and visits to an office support staff member. Study Design: A single-blind, randomized, controlled trial in 280 African-American primary care patients aged 40-75 with poorly controlled hypertension (HTN). The intervention group receives a practice-based team intervention that combines peer coach with office staff (i.e., medical assistant or licensed practice nurse) visits to address lifestyle challenges. Both intervention and control groups receive informational materials and healthy soul food recipes from the American Heart Association. The 6 month intervention alternates monthly phone calls from peer coaches about lifestyle behavioral changes with office-based visits with the support staff member during which patients review and discuss low literacy slide shows about healthy behaviors as well as examine their personal cardiovascular risk profile.
NCT02695134
The purpose of the investigators proposed randomized, controlled study is to examine the effect of 6 one hour treatments of Healing Touch (HT) over 3 weeks on post-cardiac event patients, while they wait to enter a Cardiac Rehab (CR) program.Patients enrolled in the Scripps Center for Integrative Medicine (SCIM) Cardiac Rehab Program typically experience a waiting period of 3 weeks, or sometimes more, before starting the program. Secondary aims of the proposed study are to evaluate the effect of HT on CR program outcome measures of METs, BMI, physical and mental well-being, and attendance in this population. New participants in the CR program who qualify and agree to participate in the study will be consented and randomly assigned to the Intervention Group who will receive Healing Touch therapy, or to the Control Group, which will not receive HT. At baseline both groups will complete the Dartmouth Quality of Life and SF-36 Health Surveys. The questionnaires will be repeated at the end of the 3 week study period and at the end of the 3 months SCIM CR program. An effect size of 15% was chosen, with an alpha level of 0.05, 80% power, 95% confidence level, and using a two-tailed test, it was determined that a sample size of 56 patients in each group would be needed for between group comparisons. To account for potential attrition the study will enroll 124 subjects, 62 in each group. Our rationale is that Healing Touch, in addition to standard medical care will reduce post-cardiac event stress and anxiety symptoms in patients waiting to enter a cardiac rehab program, as measured by the Dartmouth Quality of Life Index and the SF36 questionnaire. Further, the investigators suggest that Healing Touch treatments will improve patient's final outcomes of the 12 week CR program.

NCT02111226
Heart disease and stroke are the number one killers world-wide. When someone has hypertension, the constantly elevated blood pressure damages their blood vessels and the organs that they supply blood to. This causes stroke, heart attack, heart failure, kidney failure and dementia. Finding and lowering high blood pressure to normal with lifestyle changes and if necessary medications, lowers the risk of these outcomes. Canada has high rates of blood pressure control compared to other countries in the world, due in large part to the successful dissemination of hypertension guidelines. However remote and disadvantaged communities have not been as successful and need additional measures to help achieve the same level of blood pressure control as the rest of the country. The DREAM-GLOBAL team has extensive experience working with Canada's Aboriginal Communities and a large community in Tanzania. The DREAM-GLOBAL project will integrate innovations in technology with the implementation of guidelines-based blood pressure control and through partnerships with experts in government and industry, overcome barriers to lowering blood pressure in Canada's Aboriginal Communities, and in a community in Tanzania. Tools will be developed and tested that will close the circle of care around people with hypertension by bringing measurement data to the medical record and health care provider and also sending useful medical feedback to the person with hypertension via secure data servers and routine SMS messaging on cell phones. The system will be tested for effectiveness of diagnosing and also for managing hypertension. To begin the process of preventing hypertension, the team will also explore with an Aboriginal community how to create policies to reduce the sodium content in their food. If proven effective, DREAM-GLOBAL can also become a platform for managing other chronic diseases.

NCT03217240
Advances in paediatric cardiology and cardiac surgery have enabled the survival of most patients born with congenital heart disease (CHD) into adulthood. Many CHD patients have undergone palliative or reparative surgery earlier in life. As patients survive into adulthood, they may need intervention or surgery for residual haemodynamic lesions. This is because they are at risk of arrhythmias secondary to structure heart disease and are susceptible to acquired heart disease. In these patients, pre-operative and post-operative evaluation of right ventricular (RV) structure (shape and volume) and function is an essential component of clinical management. Advances have been made in cardiac imaging so that accurate assessment of the right heart chamber in terms of its structure, function and physiology is possible. However, this technology has as yet never been applied in an effort to comprehensively assess RV structure, function and physiology. Cardiac Magnetic Resonance (CMR) will be used in this comprehensive assessment of structure and function. Thus, this research will allow development of a comprehensive integrated biomedical engineering (BME) R\&D platform for in-depth study and clinical diagnosis of the RV structure-function relationship and physiology and its association with biomarker, and exercise capacity in CHD.
