25 Clinical Trials for Various Conditions
The overall objective of the DISCERN study is to develop and validate a genomic diagnostic assay to identify patients at increased risk for lethal ventricular arrhythmias and sudden cardiac death (SCD).
Beta blockers have been shown to decrease the risk of intraoperative cardiac events in patients at high cardiac risk. However, they have also been associated with side effects (for instance, stroke.) The role of beta blockers in patients at intermediate cardiac risk undergoing surgery is controversial. Heart rate variability is a way of evaluating the cardiac function of a patient. Decreased heart rate variability is associated with early cardiac death in patients with congestive heart failure (CHF) and after a heart attack. It has been shown to transiently decrease in patients in hemorrhagic shock after trauma and returns to normal after resuscitation in trauma and burn patients. The investigators hypothesize that beta blockers will maintain pre operative heart rate variability in patients with intermediate risk of cardiac events during operative intervention with laparoscopic surgery.
The objective of this pilot study is to evaluate the prevalence of biological aspirin resistance in women at risk for CHD taking low dose (81 mg) aspirin. Aspirin responsiveness will be measured with the VerifyNow device (Accumetrics; San Diego, CA). Those women identified as biologically resistant will be switched to aspirin 325 mg for 14 days and then re-tested for aspirin responsiveness.
This will be a prospective cross-sectional study evaluating a convenience sample of patients in the ED with low-risk chest pain defined by a HEART score of 3 or less.
Patients undergoing liver transplantation (LT) have a high risk for cardiovascular disease (CVD). Frailty is a frequent condition among LT candidates. Together, CVD and frailty are major causes of morbidity and mortality before and after LT. Conventional methods to diagnose and predict CVD in LT candidates lack sensitivity and clinically relevant application. However, cardiopulmonary exercise testing (CPET) can directly estimate coronary artery disease, cirrhotic cardiomyopathy, and indirectly assess frailty. Such versatility of CPET has caused it to become the standard of care in many LT centers outside of the United States. In preliminary work (funded internally by the Pittsburgh Liver Research Center) that will be used to fund a more definitive study (RO1), the investigators plan to investigate CVD and frailty in LT candidates, both from existing standard of care (SOC) methods and CPET. The investigators expect results to improve the current capacity to assess and prognosticate CVD and frailty in LT, ultimately changing practice.
This is a multicenter, randomized, double-blind, parallel group study to investigate the efficacy of pemziviptadil (PB1046) by improving the clinical outcomes in hospitalized COVID-19 patients at high risk for rapid clinical deterioration, acute respiratory distress syndrome (ARDS) and death. The study will enroll approximately 210 hospitalized COVID-19 patients who require urgent decision-making and treatment at approximately 20 centers in the United States.
This study aims to evaluate the effect of a novel hemodynamic management and monitoring strategy for reducing cardiac bio marker elevations and major adverse cardiac events.
The purpose of this study is to determine if Apixaban is safer than a Vitamin K Antagonist given for 6 months in terms of bleeding in patients with an irregular heart beat (atrial fibrillation) and a recent heart attack or a recent procedure to open up a blood vessel in the heart. All patients would also be taking a class of medicines called P2Y12 inhibitors (such as clopidogrel/Plavix) and be treated for up to 6 months. The primary focus will be a comparison of the bleeding risk of Apixaban, with or without aspirin, versus a Vitamin K antagonist, such as warfarin, with or without aspirin.
The purpose of the study is to see if using 2% Chlorhexidine cloths will reduce surgical site infections in patients having elective cardiac surgery.
The purpose of this study is to look at a new method for finding out if patients have a risk of heart complications from surgery. At the present, to find out if patients have a risk of heart complications from surgery, look at whether the patient has heart disease, diabetes, kidney problems, and stroke. The investigators hope that this study will confirm a new, safe test to help us predict the risk of surgery.
The primary objective of this study is to determine the degree of additional reduction in cardiovascular risk that was accrued to patients by lowering their LDL-C beyond the currently accepted minimum target level for patients with pre-existing CHD. Secondary objectives include the safety profile of this treatment strategy, its cost-effectiveness, effect on other atherosclerotic-related events and procedures, and total mortality.
CKJX839D12302 is a pivotal Phase III study designed to test the hypothesis that treatment with inclisiran sodium 300 milligram (mg) subcutaneous (s.c.) administered on Day 1, Day 90, and every 6 months thereafter in patients at high cardiovascular (CV) risk without a prior major atherosclerotic cardiovascular disease (ASCVD) event will significantly reduce the risk of 4-Point-Major Adverse Cardiovascular Events (4P-MACE) defined as a composite of CV death, non-fatal myocardial infarction (MI), non-fatal ischemic stroke, and urgent coronary revascularization, compared to placebo.
This is a non-randomized, non-interventional pilot observational study designed to follow high-risk patients through their surgical and hospital stay. The investigators will collect 2 4ml vial's of blood (total of 8ml) prior to surgery to assess CV biomarkers - inflammatory, metabolic, hypercoagulable and platelet.
AMR101 (icosapent ethyl \[ethyl-EPA\]) is a highly purified ethyl ester of eicosapentaenoic acid (EPA) developed by Amarin Pharma Inc. for the treatment of cardiovascular disease in statin-treated patients with hypertriglyceridemia. The purpose of this study was to evaluate whether this drug, combined with a statin therapy, will be superior to the statin therapy alone, when used as a prevention in reducing long-term cardiovascular events in high-risk patients with mixed dyslipidemia.
A committee will judge the safety and effectiveness of edoxaban and the regular treatment (standard of care). All children in the study will receive free treatment. They will have a 2 in 3 chance to receive edoxaban, and a 1 in 3 chance to receive the standard of care for preventing blood clots. The study will find out if edoxaban is safer and more effective than the standard of care.
Arrhythmias remain a major health problem, causing at least 250,000 deaths annually in the United States. Pharmacological treatments often do more harm than good, and device therapies are limited by high cost and effects on quality of life. Ion channel mutations cause rare inherited arrhythmopathies, but account for only a small fraction of patients with life- threatening arrhythmias and sudden death. Most arrhythmias occur during myocardial ischemia, following myocardial infarction, and in patients with poor left ventricular (LV) function of any etiology. Aside from ejection fraction (EF), few clinically useful indicators to stratify the risk of sudden death have been identified. The role of subtle difference in ion channel expression and/or structure in predisposing patients to arrhythmias and modulating the risk of sudden death is unknown. In this study, we are prospectively testing whether polymorphisms in ion channels and ion channel modifying genes are associated with arrhythmias in a population with internal cardioverter-defibrillators (ICDs) and poor LV function. We will test the hypothesis that functional polymorphisms in the coding sequences and promoter regions of cardiac genes (e.g. ion channels, beta-adrenergic receptors) predispose individuals to arrhythmias and /or heart failure progression. We hope to identify genetic predictors for the common forms of sudden cardiac death. This would allow the identification of a subpopulation of heart failure patients that would benefit most from ICD placement.
This is a prospective study to evaluating the ability of the PD2i Cardiac Analyzer to predict the risk of serious heart rhythm abnormalities in high-risk patients that do not already have an Implantable Cardioverter Defibrillator.
The study aims to support patients immediately after percutaneous coronary intervention (PCI) by implementing a telemonitoring program. Eligible patients have coronary heart disease and undergo PCI. The intervention group receives remote monitoring and text-based follow-up, with established health goals and education on using the telemonitoring application, along with necessary devices. The control group gets standard care. Outcomes measured include blood pressure, LDL levels, patient satisfaction, revascularization, and mortality. The study findings will enhance patient care after PCI and contribute evidence for widespread telemonitoring implementation in healthcare systems, aiding medical therapy and lifestyle modifications.
Implement an intensive cardiac rehabilitation program at Arkansas Heart Hospital (AHH) to find out if the AHH-ICR is equivalent to the CMS approved programs when it comes to results.
This trial is designed to evaluate QPI-1002 versus placebo for the prevention of Major Adverse Kidney Events (MAKE) in subjects at high risk for acute kidney injury following cardiac surgery. Half of the participants will receive QPI-1002 while the other half will receive placebo.
Polypharmacy is common among older adults in the United States and is associated with harms such as adverse drug reactions and higher costs of care. This pilot-phase project is designed to test two electronic health record (EHR)-based behavioral economic nudges to help primary care clinicians reduce the rate of high-risk polypharmacy among their older adult patients.
Sudden cardiac death continues to be a major contributor to mortality in patients with ischemic cardiomyopathy. While implantable defibrillators can prevent death from ventricular arrhythmias, our current approach to identify patients at highest risk primarily rests on demonstrating a reduction in left ventricular ejection fraction less than 35%. The purpose of this observational cohort study is to prospectively test whether this can be enhanced by quantifying the amount of sympathetic denervation, left ventricular end-diastolic volume or brain natriuretic peptide levels.
The primary objective of the study was to compare the effect of sotagliflozin to placebo on total occurrences of cardiovascular (CV) death, hospitalization for heart failure \[HHF\], and urgent visit for heart failure \[HF\] in participants with type 2 diabetes, cardiovascular risk factors, and moderate to severely impaired renal function.
A novel Cardiac MRI sequence, developed by Dr. Maria Altbach (Double Inversion radial fast Spin Echo T2 mapping), has been tested clinically. It demonstrated a high sensitivity to the heart muscle swelling ("edema") in different types of heart injury, including heart attacks. The investigators propose to use T2-Map methodology in patients with acute heart attacks and to compare value of this method with other clinical and imaging parameters in predicting short-term (30 day) clinical outcomes of these patients. If successful, the project will provide an effective risk-stratification tool to identify patients with heart attack as a result of atherosclerotic disease, who require more aggressive therapeutic approach and closer follow-up after initial hospitalization.
The main purpose of this study is to determine if retatrutide can significantly lower the incidence of serious heart-related complications or prevent the worsening of kidney function. The trial will enroll adults with body mass index 27 kg/m\^2 or higher and Atherosclerotic Cardiovascular Disease and/or chronic kidney disease. The study will last for about 5 years. Participants will have up to 27 clinic visits with the study doctor.
