Cell Free DNA in Cardiac Sarcoidosis
Sarcoidosis is a multisystem granulomatous disease of unknown cause that can affect any organ in the body, including the heart. Granulomatous myocarditis can lead to ventricular dysfunction and ventricular arrhythmias causing significant morbidity and mortality. Immunosuppressive therapy (IST) has been shown to reverse active myocarditis and preserve left ventricular (LV) …
Early Cardiac Magnetic Resonance Imaging in Suspected Non-ST-Elevation Myocardial Infarction
Background and rationale: Evaluating patients with acute chest pain, elevated high-sensitive cardiac troponin (hs-cTn) levels and non-diagnostic electrocardiogram (ECG), i.e. suspected non-ST elevation myocardial infarction (MI), is a daily challenge. Although contemporary hs-cTn assay-based algorithms have greatly facilitated clinical decision-making, still one-quarter of patients is categorized as 'observe' group and …
MCG Discovery Study in Emergency Departments
This prospective discovery study is designed to demonstrate the feasibility of using an unshielded, mobile MCG device in an Emergency Department (ED) setting. The main question it aims to answer is whether interpretable data can be reliably collected as part of an ED workflow.
Peri-Procedural Transmural Electrophysiological (EP) Imaging of Scar-Related Ventricular Tachycardia
Ventricular tachycardia (VT) contributes to over 350,000 sudden deaths each year in the US. Malignant VTs involve an electrical "short circuit" in the heart, formed by narrow channels of surviving tissue inside myocardial scar. An important treatment is to use catheter ablation to "block" the channel that forms the circuit. …
Cardiac Radioablation for VT
The goal of this interventional study is to determine the minimum dose necessary for successful cardiac radioablation of refractory ventricular tachycardia (VT) and to study the utility of target volume definition using Delayed Enhancement Cardiac MRI (DE-CMR) .
Cohort Study - SBRT for VT Radioablation
Ventricular tachycardia (VT) contributes to over 350,000 sudden deaths each year in the US. Malignant VTs involve an electrical "short circuit" in the heart, formed by narrow channels of surviving tissue inside myocardial scar. Current treatment for VT consists of either implantable defibrillators (ICDs), suppressive drug therapy, catheter ablation or …
Identification of Genomic Predictors of Adverse Events After Cardiac Surgery
This study aims to identify genetic causes of adverse events after cardiac surgery, such as atrial fibrillation, myocardial infarction, renal dysfunction and heart failure. Patients undergoing heart surgery at Brigham and Women's Hospital and Texas Heart Institute are eligible to participate.
Metformin and Prevention of Cardiovascular Events in Patients With Acute Myocardial Infarction and Prediabetes (MIMET)
Prediabetes is associated to an increased risk of cardiovascular disease and mortality. Although metformin can delay progression to diabetes there is a lack of RCTs evaluating the effect of metformin on cardiovascular outcomes. MIMET aims to investigate if addition of metformin to standard care has effects on the occurrence of …
High-Sensitivity Troponin T Plasma Levels in Patients With Aortic Stenosis (Tyrolean Aortic Stenosis Study-2)
TASS-2 (Tyrolean Aortic Stenosis Study-2) aims to characterize the clinical value of minimally elevated troponin T plasma levels both in patients with asymptomatic and symtomatic aortic stenosis.
LIVEBETTER: A Trial Comparing Medications in Older Adults With Stable Angina and Multiple Chronic Conditions
To establish the effectiveness and tolerability of standard of care anti-anginal treatment (beta-blocker and calcium channel blocker medications) in older adults with symptomatic Stable Ischemic Heart Disease (SIHD) and multiple chronic conditions (MCC).
