Filter by:Investigators will determine whether N-of-1 trials, as a pragmatic, patient-centered approach to medication optimization that can overcome key barriers of deprescribing, can lead to increased subject confidence regarding the decision to continue or discontinue beta-blockers in older adults with Heart Failure with Preserved Ejection Fraction (HFpEF).
Recent studies have shown that transthyretin amyloidosis (ATTR) can sometimes cause a type of heart failure where the pumping function of the heart is normal, also known as Heart Failure with Preserved Ejection Fraction (HFpEF) or diastolic heart failure. In this single center diagnostic study, we will evaluate for ATTR in patients with HFpEF in order to to determine how frequently this occurs and how we can predict which heart failure patients may have TTR amyloidosis. Our goal is to identify amyloidosis in heart failure patients earlier so that they can start treatment.
Heart failure (HF) with a left ventricular ejection fraction (LVEF) >0.40 is a large medical problem, for which no drug or device has a recommendation in current HF guidelines. The prevalence of mortality and HF hospitalizations in HF with LVEF >0.40 is high, but the identification of predictors for increased risk of mortality and HF hospitalizations in this patient category remains difficult. The hypothesis of this study is that the risk of all-cause mortality and HF hospitalizations can be measured by clinical factors, imaging parameters and circulating biomarkers, and that these factors can be used in a risk profile
Multicenter, Prospective, Randomized, Sham Controlled, Double Blinded Clinical Trial, with; 1:1 randomization
Our local IRB approved clinical studies seeking proof of principle for the hypothesis that SFN can be safely administered to humans at doses sufficient to protect age-associated cardiac dysfunctions. Beneficial effects of SFN-therapy will be assessed by Pre- and post-intervention echocardiography, and exercise endurance at 0 and 24 weeks. Peripheral blood cells from treated and control subjects will be compared for mitochondrial respiratory function, oxidative damage, pro-inflammatory cytokines, and expression of antioxidant & anti-electrophile genes.
This study explores whether spermidine supplementation improves the metabolic, neurological-cognitive and cardiovascular response to structured exercise training in patients with heart failure with preserved ejection fraction. The investigators aim to show that a faster adaptation to exercise may improve long term adherence to a more active lifestyle.
The AIM HIGHer Clinical Trial will evaluate the safety and efficacy of Cardiac Contractility Modulation (CCM) therapy in patients with heart failure with LVEF ≥40% and ≤60%.
Heart Failure (HF) is a complex disease associated with the highest burden of cost to the healthcare system. The cardiopulmonary exercise test (CPET) is instrumental in determining the prognosis of patients with HF. This study will evaluate whether aggregate biometric data from the Apple Watch combined with demographic, cardiac, and biomarker testing can improve our ability to predict heart failure outcomes among a diverse ambulatory HF population
In a prospective cohort study (n = 1.000), the investigators aim to investigate the correlation between cardiac biomarkers and advanced echocardiography and determine whether these are prognostic markers of heart disease in patients suffering from psoriasis.
Low level transcutaneous vagus nerve stimulation (LLTS) involves delivery of electrical impulses transcutaneously at the auricular branch of vagus nerve and it has been shown to have anti-inflammatory and anti-arrhythmic effects. In previous studies from our laboratory, we found that LLTS significantly suppressed atrial fibrillation (AF) inducibility and decreased AF duration. The anti-arrhythmic effects of LLTS were similar to those delivered to the cervical VN trunk. LLTS for just one hour significantly shortened the AF duration and decreased inflammatory cytokines. We have also shown that LLTS leads to favorable heart rate variability (HRV) changes and cardiac mechanics in patients with diastolic dysfunction. These results support the use of LLTS as a novel non-pharmacological, non-ablative treatment modality for AF and possibly other inflammatory conditions. However, the optimal stimulation parameters of LLTS remain to be determined. In this study, we aim to examine the effect of 2 different frequencies (5Hz and 20Hz) and 2 different amplitudes (50% below the pain threshold and 1mA below the pain threshold) of LLTS on heart rate variability with deep breathing (HRVdb), mental arithmetic stress test (MAST), frequency domain measures of heart rate variability (HRV) and brain stem evoked potentials (BSEVP) in healthy volunteers and patients with AF or heart failure with preserved ejection fraction (HFpEF). HRV is a marker of vagus nerve activity and can be easily measured by software calculating the distance between consecutive R waves on the ECG. BSEVP are a surrogate for the central projections of the vagus nerve. Patients will be randomized into 4 groups in a 2x2 factorial design. LLTS will be delivered through a transcutaneous electrical nerve stimulation (TENS) device for 15 minutes. HRVdb, HRV and BSEVP will be measured before and after LLTS and compared.
