NCT00887588
The study will assess the effects of 36 weeks of treatment with LCZ696 compared to valsartan on N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) in patients with chronic heart failure and preserved left-ventricular ejection fraction.
NCT00997503
The TAXUS Libertē Post-Approval Study is an FDA-mandated prospective, multi-center study designed to collect real-world safety and clinical outcomes in approximately 4,200 patients receiving one or more TAXUS Liberté Paclitaxel-Eluting Stents and prasugrel as part of a dual antiplatelet therapy (DAPT) drug regimen. This study will also contribute patient data to an FDA-requested and industry-sponsored research study that will evaluate the optimal duration of dual antiplatelet therapy (DAPT Study).
NCT01478061
The Study plan is a post-market prospective, multi-center, open-label registry. The vein graft failure rates for the currently commercialized C-Port devices will be compared to an a priori rate taken from the peer-reviewed literature.
NCT00094302
The purpose of this study is to evaluate the effectiveness of aldosterone antagonist therapy in reducing cardiovascular mortality, aborted cardiac arrest, and heart failure hospitalization in patients who have heart failure with preserved systolic function.
NCT01408303
The primary objective is to evaluate the efficacy of adding Epanova (2 g or 4 g daily) to an optimal statin monotherapy for lowering non-high-density lipoprotein (non-HDL) cholesterol in subjects with persistent hypertriglyceridemia and high risk for cardiovascular disease.
NCT01425359
This study will evaluate the effect of ranolazine compared to placebo on the average weekly angina frequency in subjects with chronic stable angina and coronary artery disease (CAD) who have a history of type 2 diabetes mellitus (T2DM), and whether ranolazine can reduce the frequency of angina (chest pain) attacks, compared to a placebo. Subjects will be asked to record their daily angina episodes in a diary at the end of each study day. Ranolazine is approved for the treatment of chronic angina, and is not approved for the treatment of T2DM.
NCT00041938
The purpose of this study is to determine which of two treatments, Warfarin or aspirin, is better for preventing death and stroke in patients with poor heart function. We are now transitioning into the sub-analysis part of the WARCEF patient data. The study has recently completed data analysis for its Primary Aim. All randomized patients have completed their follow up. All study related procedure as per the protocol has been completed. We are now in the extension phase of the study to obtain more patient data to address further aims of the study. No new procedures are performed and data already in place at the sites will be collected (EKG and echocardiograms). The aims for this study extension are: * To assess progression of cardiac dysfunction over time among heart failure patients * To correlate prognosis with cardiac dysfunction
NCT00738049
The primary objective of this study is to test the hypothesis that myocardial perfusion heterogeneity, quantified by Markovian Homogeneity analysis of cardiac PET perfusion images, will improve in a quantitative manner after treatment with selective ETA receptor antagonist darusentan 100 mg per day for 2 weeks compared to baseline and post-treatment PET scans in clinically stable subjects with coronary atherosclerosis and/or risk factors.
NCT00763867
Diastolic heart failure (DHF), which affects older individuals and women at a disproportionate rate, is a condition that can lead to shortness of breath and fluid build-up in the lungs. This study will evaluate the effectiveness of the medication sildenafil at improving exercise ability and health outcomes in people with DHF.
NCT00201084
The purpose of this study is to test the theory that a major factor in poor blood pressure (BP) control is that physicians fail to intensify antihypertensive therapy for their patients.
NCT00032370
Although a number of sophisticated diagnostic tests have been shown to be helpful in identifying patients at high risk for perioperative cardiac complications, no study has addressed the most important question: Should prophylactic coronary revascularization be performed prior to elective vascular surgery? This study is designed to answer this question.
NCT01414309
Central sleep apnea (CSA) has been associated with increased mortality and primarily occurs in patients with heart failure (HF). The primary purpose of this study is to document the natural progression of moderate to severe CSA in heart failure patients.
NCT00803634
The purpose of this study was to evaluate the efficacy and safety of intravenous (IV) clevidipine as compared with standard of care IV antihypertensive agents for blood pressure (BP) lowering in patients with acute heart failure and elevated BP.
NCT01419171
The purpose of this study is to evaluate the safety and effectiveness of the OMEGA Coronary Stent System for the treatment of subjects with a de novo atherosclerotic coronary artery lesion.
NCT01605292
Radial artery access for cardiac catheterization can require multiple attempts. Multiple attempts increase the time required, patient discomfort, and the risk of arterial spasm. Ultrasound guidance has been shown in other studies to reduce the number of attempts and complications in central venous and femoral artery access. This study will test if the addition of ultrasound guidance reduces the number of attempts and time required to access the radial artery.
NCT01067859
A placebo controlled, double-blind and randomized study to assess different doses of a new drug (BAY58-2667) given intravenously, to evaluate if it is safe and can help to improve the well-being of patients with acute decompensated heart failure.
NCT01200160
Post-Marketing Observational study of Niaspan® tablet in accordance with each country regulations. This study will be conducted in a prospective, single-arm, multi-center format. As this study is observational in nature, the follow-up of subject's is not prescriptive in nature and is according to the judgment of the physician (investigator in the course of treatment for each patient), within the period of observation of 12 months. This includes an enrollment period of 6 months in which each subject will be observed for approximately 6 months. Examinations, diagnostic measures, findings and observations performed as per usual medical practice during the observation period will be recorded on Case Report Forms (CRFs) by the investigator or site staffs according to the protocol.
NCT01740895
To assess the clinical value of iFR to characterize, without concomitant administration of hyperemic agents and outside a specified range of iFR values, coronary stenosis severity as determined with fractional flow reserve (FFR)
NCT01523366
The purpose of this study is to assess the pharmacodynamic effect of ticagrelor in Hispanic patients with stable coronary artery disease.
NCT01272453
This is a prospective, controlled observational trial of patients undergoing clinically indicated cardiothoracic computed tomography (CT), including pulmonary or aortic angiography and coronary CT angiography (CCTA).
