The purpose of this study is to test the effect of prolonged therapy (24 weeks) with isosorbide dinitrate ± hydralazine on arterial wave reflections, exercise capacity, left ventricular (LV) mass/fibrosis and diastolic function in patients with Heart Failure and Preserved Ejection Fraction (HFPEF). This is a double-blind, placebo-controlled pilot randomized …
This is a prospective, single-center, randomized double-blind, placebo-controlled, crossover study conducted in the United States (US). Patients will be randomized into two treatment sequences (treatment A in period 1, followed by treatment B in period 2, or treatment B in period 1, followed by treatment A in period 2). At …
Subjects with symptomatic PAF who have had at least one AF episode documented within one (1) year prior to enrollment and who have failed at least one antiarrhythmic drug (AAD). The Main Study will consist of a prospective, multi-center, randomized (1:1 concurrent nMARQ Catheter System [nMARQ] vs THERMOCOOL® Navigational Family …
The purpose of the study is to compare the effectiveness of the Cool Flex Irrigated Catheter Ablation System to routine drug therapy without ablation to treat VT or prevent VT from developing in patients at risk. The study will also evaluate the safety of the catheter device. Information on the …
The purpose of the research study is looking at a new algorithm (step by step approach) for patients with heart failure who are indicated for an BiV (biventricular) pacing device.
The primary efficacy objectives of this study are to demonstrate that sensitivity and specificity of gadobutrol-enhanced CMRI exceed prespecified minimum performance thresholds (MPT) of 60% and 55%, respectively and to show superior sensitivity over unenhanced wall motion CMRI at vasodilator rest/stress for the detection of significant coronary artery disease (CAD) …

Over the past 2 decades, there has been a significant increase in life span of patients with cancer so that now, there are more than 10 million cancer survivors in the U.S. [1]. There is a growing recognition that although survival has improved, many long-term side effects including cardiac complications …
Tyrosine kinase inhibitors such as sunitinib are used in the treatment of renal cell carcinoma and have significant off-target effects with cardiac toxicity and resultant ventricular cardiac dysfunction being a major concern. However, the mechanisms of these effects in humans remains poorly defined, as are the clinical methods to risk …
