NCT01638897
The purpose of this study is to evaluate long-term performance of the DF4 Connector System. This evaluation is based on the number of DF4 lead-related complications occurring during the study compared to the number of leads enrolled in the study. The DF4 systems will be followed for 5 years after implant. This study is required by FDA as a condition of approval of the DF4 Connector Systems. This study is conducted within Medtronic's post-market surveillance platform.
NCT01663402
Primary Objective: To compare the effect of alirocumab with placebo on the occurrence of cardiovascular (CV) events (composite endpoint of coronary heart disease (CHD) death, non-fatal myocardial infarction (MI), fatal and non-fatal ischemic stroke, unstable angina (UA) requiring hospitalization) in participants who experienced an acute coronary syndrome (ACS) event 4 to 52 weeks prior to randomization and were treated with evidence-based medical and dietary management of dyslipidemia. Secondary Objectives: * To evaluate the effect of alirocumab on secondary endpoints (any CHD event , major CHD event, any CV event, composite of all cause mortality/non-fatal MI/non-fatal ischemic stroke, CHD deaths, CV deaths, all cause mortality). * To evaluate the safety and tolerability of alirocumab. * To evaluate the effect of alirocumab on lipid parameters.
NCT00453622
The purpose of the study is to identify if the combined use of cardiac troponin enzyme (cTnT) and brain natriuretic peptide (BNP) can predict Heart Failure (HF)improvement and all-cause mortality in patients implanted with cardiac pacemaker-defibrillation devices (CRT-D). Novel biochemical markers identifying patients with high risk cardiac mortality detected by plasma protein analysis will also be evaluated. Hypothesis #1: The combined use of cTnT and BNP at just before implant will predict and risk stratify all cause mortality or HF hospitalization up to 12 months. Hypothesis #2: The change in levels of said biomarkers at different points of follow-up can predict response to CRT through 12 months. Hypothesis #3: The levels of a panel of novel inflammatory mediators, namely chemokines, will be correlated with improvement in 6-minute walk testing, quality of life, and left ventricular ejection fraction in CRT patients.
NCT01786993
This IDE study is a prospective, randomized, double-blind, multi-center clinical study to evaluate the safety and efficacy of patient treatment with MPP compared to patient treatment with standard BiV pacing at 9 months. The study will be conducted at a maximum of 50 investigational centers located in the United States. A maximum of 506 subjects implanted with the Quadripolar cardiac resynchronization therapy device (CRT-D) system will be enrolled in the study.
NCT02679690
Develop an evidence-based intervention aimed at patients with heart failure (HF) using color-coded cue cards to assist in the selection of foods appropriate to their sodium restricted diet. The milligram per serving sodium content of foods will be assigned color-coded green/yellow/red designation according to very low/moderate/high as identified by the United States Food and Drug Administration's definitions of sodium content. Assess patient knowledge of foods with sodium content appropriate for consumption on a low sodium diet before implementation of the intervention by calculating average milligrams of sodium per serving via choices made through simulated grocery store shopping. Evaluate application of patient knowledge about low-sodium food choices using a simulated grocery store shopping intervention by calculating average milligrams of sodium per serving via choices made using the color-coded card.
NCT00303979
The purpose of this study is to characterize current management of patients with either heart failure or prior myocardial infarction and left ventricular dysfunction and to assess the effect of education, specific clinical guidelines, reminder systems, comprehensive disease state management tools, benchmarked quality reports, and academic detailing on the use of evidence-based heart failure therapies in cardiology practices. This study is a quality improvement initiative that is being conducted through review of patient records.
NCT00807040
People with coronary artery disease (CAD) or people who have had a heart attack may develop a leak in the mitral valve of their heart and may therefore need to undergo surgery to fix the valve. The best way to fix the mitral valve remains undetermined. This study will evaluate whether it is better for people with severe mitral valve leakage to undergo a mitral valve replacement procedure or a mitral valve repair procedure.
NCT01076348
Safety and effectiveness will be summarized for the model 4965 lead. This study was conducted within Medtronic's System Longevity Study (SLS).
NCT00916929
To demonstrate the safety and effectiveness of the Impedance Monitoring Feature in St Jude Medical cardiac devices.
NCT02548455
The primary intent of this study is to assess the safety of the model 1457Q Quartet LV lead at 3 months in a patient population indicated for cardiac resynchronization therapy.
NCT01498692
The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions. The lesions can be located in vessels that are smaller than average-sized.
NCT01500434
The purpose of this study is to evaluate the safety and effectiveness of the PROMUS Element™ Everolimus-Eluting Coronary Stent System for the treatment of patients with up to 2 de novo atherosclerotic coronary artery lesions. The lesions can be longer than average-sized.
NCT00927784
Left ventricular assist devices (LVADs) are one treatment option for people with congestive heart failure. This study will evaluate the safety of injecting mesenchymal precursor cells (MPCs) into the heart during LVAD implantation surgery and examine if injecting MPCs into the heart is effective at improving heart function.
NCT01826019
The overall objective of the HOPE-4 Phases (HT and CVD) is to develop, implement and evaluate an evidence-based, contextually appropriate programme for cardiovascular disease (CVD) risk assessment, treatment and control involving: (1) simplified algorithms implemented by non-physician health workers (NPHW) and supported by e-health technologies (tablets programmed with decision and counselling support software); (2) initiation of evidence-based cardiovascular (CV) medications and (3) treatment supporters to optimize long-term medication and lifestyle adherence.
NCT03169530
The Moderate Alcohol and Cardiovascular Health Trial (MACH15) is a multicenter, worldwide, randomized clinical trial of \~15 gm of alcohol daily versus abstention, using a balanced parallel design and single-blind assessment of all outcomes among approximately 7,800 participants aged 50 years and older with advanced cardiovascular risk. Intervention will average 6 years in duration with a common close-out date. Following recruitment and pre-screening, participants will attend a screening visit followed by a two-week abstention washout period, a baseline visit and randomization, and subsequent visits at 3 months, 6 months, 12 months, and then annually until close-out.
NCT01993862
The purpose of this study is to determine whether it is safe to send patients home from the hospital on the same day following an implantable cardioverter defibrillator (ICD) implant.

The study objectives are to determine the effectiveness of structured access to a Wii game computer compared to motivational support only in heart failure patients on exercise capacity and daily activity. Secondly, to determine the effectiveness of structured access to a Wii game computer compared to motivational support only in heart failure patients on the combined endpoint of death, readmission and quality of life. The following research questions will be addressed: * What is the effectiveness of structured introduction and access to a Wii game computer in patients with heart failure to improve their exercise capacity compared to patients with heart failure in a control group who only receive motivational support? * What is the effectiveness of structured introduction and access to a Wii game computer in patients with heart failure compared to patients with heart failure in a control group who only receive motivational support to increase their daily physical activity, decrease health care use and improve quality of life? * What are experiences of heart failure patients and how is their exercise motivation when they are introduced and instructed to play with a Wii game computer?
