Clinical Trials

This is a prospective, non-randomized, multicenter, pivotal Investigational Device Exemption (IDE) study. The intent of this study is to demonstrate the safety and effectiveness of the ST Monitoring Feature in St Jude Medical ICD systems.

The purpose of this study is to  identify the best timing of revascularization with coronary bypass surgery in patients  presenting with acute coronary syndrome and treated with Ticagrelor at an early time point.

The purpose of this study is to determine if testing patients for endothelial dysfunction will help identify which patients are more likely at risk to have another heart attack in the future. Study participants will undergo mental stress testing while at the same time being connected to a device that measures endothelial function via the Endopat device. These same participants will also undergo a sleep study via the Watchpat device.

This is a phase 3, multicenter, double-blind, randomized, placebo-controlled, parallel-group study to evaluate the efficacy and safety of CSL112 on reducing the risk of major adverse CV events [MACE - cardiovascular (CV) death, myocardial infarction (MI), and stroke] in subjects with acute coronary syndrome (ACS) diagnosed with either ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI), including those managed with percutaneous coronary intervention (PCI) or medically managed.

The purpose of this study is to see if using two-dimensional speckle tracking echocardiography improves the initial diagnosis of acute coronary syndrome in patients with chest pain who visit the emergency department. 

The purpose of this study is to validate the diagnostic accuracy of a transportable magnetocardiograph device for acute coronary syndrome (ACS), focusing on rule-out capability, in patients who present to the emergency department with chest pain symptoms consistent with ACS.

The objectives of this study are to measure psychosocial cardiac distress* in Latinx/Latino/Hispanic (L/H) women with a history of an acute coronary syndrome (ACS), as well as those with traditional cardiovascular risk factors, but no ACS (diabetes, hypercholesterolemia, obesity, and hypertension), to examine the effects a composite measure for psychosocial cardiac distress has on health-related quality of life (QoL) on women with ACS and those with cardiovascular risk factors and to examine the impact acculturation, acculturative stress, perceived discrimination, and familism can have on the association between cardiac distress and QoL on L/H women with ACS and cardiovascular risk factors. 

*Cardiac distress is defined as ...

The purpose of this study is to measure overall activity (sedentary-to-high intensity) during rehab and at 1 year follow-up.  

The purpose of this study is to screen for unique or characteristic circulating peptides, hormonal biomarkers and circulating mRNA in patients who have experienced spontaneous coronary artery dissection (SCAD).

The main purpose of the study is to examine the effect of two different high intensity interval training (HIIT) prescription approaches on improving fitness, heart function, and the ability of the body's muscles to receive oxygen. The two approaches of the same total exercise durston will include: 1) HIIT with progressively increased interval durations (PRO-HIIT) versus 2) HIIT with constant shorter interval durations (CON-HIIT). The study hypothesis is that the progressively increased interval duration at high-intensity (PRO-HIIT) will result in a greater increases in fitness, heart function, and the ability of the body's muscles to receive oxygen in patients enrolled in cardiac rehabilitation. 

The aim of this project is to assess the feasibility and utility of a virtual world-based cardiac rehabilitation (CR) program as an extension of a face-to-face conventional CR program (Destination Rehab).

The purpose of this study is to evaluate comparisons between a hybrid program of center-based CR which incorporates mHealth remote case management technology (CON+) to a traditional center-based program alone (CON) as well as comparisons between home-based mHealth remote case management alone (HOM+) to a traditional center-based program (CON).

Spontaneous coronary artery dissection (SCAD) is uncommon but important cause of acute coronary syndrome and sudden cardiac death. There is very little data exists in regards to patient clinical characteristics, risk factors, treatment and outcomes. Our objective is to prospectively assess long term outcomes. 

The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

The purpose of this study is to determine if apixaban given for 6 months is safer than Vitamin K Antagonist (VKA) given for 6 months in terms of major bleeding and non-major bleeding in patients with an irregular heart beat (atrial fibrillation) and a recent heart attack or in atrial fibrillation patients undergoing a procedure to open up a blood vessel in the heart (percutaneous coronary intervention). All patients would also be taking a class of medicines called P2Y12 inhibitors (such as clopidogrel). All patients would be treated for an intended 6 months.

The purpose of this study is to identify correlates of healthcare-seeking behavior in patients with ACS and CHF and its association with psychosocial and health outcomes.

The objectives of this study are to examine the prevalence of comorbid sleep disordered breathing (SDB) and insomnia in post-MI patients enrolled in cardiac rehabilitation (CR), to assess whether post-MI CR patients with comorbid SDB and insomnia exhibit a more unfavorable CV profile than those without, and to determine whether post-MI CR patients with comorbid SDB and insomnia show less adherence to CR than those without.

The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

The purpose of this study is to characterize TRPC6 risk variants for doxorubicin-related cardiotoxicity in prospectively collected samples from breast cancer patients.   

Breast cancer patients are more than three times at risk for developing congestive heart failure (CHF), compared with patients who did not have cancer. The increased risk of HF is observed as early as one year from diagnosis of cancer and overall, 7% of patients develop CHF (median follow-up 8.5 years)
