Filter by:The purpose of this study is to assess the effectiveness of squat-to-stand maneuver in eliciting left ventricular outflow gradients in patients with Hypertrophic Cardiomyopathy (HCM) compared to Valsalva, amyl nitrite inhalation, and exercise stress echocardiogram (ESE).
This is a prospective multicenter randomized open-label study aiming to assess whether endocardial or endocardial-epicardial ablation is superior to the standard approach (i.e., Antiarrhythmic drugs) in achievement of long-term ventricular tachycardia (VT) treatment success.
The purpose of this research is to investigate the effect of using this surgical technique in conjunction with bypass surgery to improve heart function and size, as well as decrease the possibility of future mitral valve surgery.
COVID-19 is associated with complications including ARDS and myocardial injury, which informs prognosis and patient outcome. The laboratory plans to perform immunophenotyping of peripheral T-cells in patients with COVID-19 and complications (ARDS, ITU admission, myocardial injury) and map this against clinical patient outcomes. The aim is to determine if there is a specific T-cell immunophenotype associated with COVID-19 and/or complications, which can be used to inform prognosis and potential therapies.
This phase II trial compares two drug therapy plans for the correction of heart function changes (reduced ejection function) in patients who have undergone anthracycline-based treatment for lymphoma, sarcoma, or breast cancer. "Reduced ejection fraction" means the left ventricle of the heart is pumping a reduced blood volume with each heartbeat. Treatment is recommended, and the purpose of this research is to compare two different drug therapy plans (standard therapy with carvedilol and lisinopril and standard therapy with carvedilol and lisinopril plus pravastatin and spironolactone) and their effects on improvement of heart function. All of these drugs are heart medications, and carvedilol and lisinopril are commonly used to improve heart function. Adding pravastatin, a cholesterol lowering drug with additional beneficial effects on the cardiovascular system, and spironolactone, a water pill with additional beneficial effects on the cardiovascular system, may lead to even better (and faster) improvements in heart function.
The purpose of this project is to evaluate parameters of diastolic dysfunction assessed by clinical echocardiogram in patients who have had recovery of systolic function.
Study evaluates the relationships between daily physical activity levels (PAL) and functional capacity (VO2peak) in patients with dilated cardiomyopathy (DCM)
The purpose of this study is to explore how the End Tidal Carbon Dioxide monitoring via nasal cannula (ETCO2-NC) device may allow for earlier detection of respiratory complications. This device will detect the amount of carbon dioxide exhaled with each breath and may better predict high levels of this than traditional monitoring. This may reduce the number and severity of respiratory issues. A convenience sample of 60 participants either scheduled for continuous flow left ventricular assist device (CF-LVAD) implant or who have been readmitted to an ICU with a CF-LVAD will be recruited and randomized to usual care or usual care plus ETCO2-NC throughout their stay in the ICU.
Peripartum cardiomyopathy (PPCM) is a rare, but significant heart disease affecting young women in the puerperal period. Thus far, no specific treatment has been approved to treat this disease. PPCM has a wide spectrum of clinical manifestations ranging from mild heart failure to severe cardiomyopathy, cardiogenic shock and death. A significant proportion of survivors have persistent chronic heart failure leading to disabling symptoms and decreased quality of life. Animal studies have suggested that prolactin is central to the development of PPCM. Prolactin has pro-inflammatory and anti-angiogenic effects that may promote PPCM. Bromocriptine, a central dopamine agonist known to decrease prolactin levels, might thwart its deleterious effects in women suffering from PPCM. Following this rationale, bromocriptine should improve myocardial function in women suffering from PPCM and thus, improve cardiovascular outcomes and healthcare outcomes.
Cardiac amyloidosis describes a process by which abnormally folded proteins infiltrate the heart tissue. Given the insidious nature of this disease process, diagnosis is often too late for a meaningful intervention. Advances in the treatment of the amyloidoses have improved outcomes for patients with these conditions. The focus of this study is to identify the involvement of the heart, most closely associated with mortality, so that aggressive management can be instituted improving prognosis.
