Filter by:The purpose of this study is to determine the effectiveness of RXI-109 in reducing the recurrence of hypertrophic scar formation following elective revision of a pre-existing hypertrophic abdominal scar.
The aim of this study is to determine whether adherence to oral maintenance medications differs for patients randomized to receive a RxTimerCap, a Take-N-Slide, a standard pillbox, or none of these devices, with the hypothesis that low-touch devices improve adherence over control and that the increase in adherence is agnostic across devices.
This study will evaluate the safety and efficacy of a range of doses of botulinum toxin Type A (BOTOX®) for the treatment of patients with bilateral Masseter Muscle Hypertrophy (MMH).
This prospective evaluation studies the effectiveness of IL cryotherapy in treating keloids and hypertrophic scars in a large population of mixed Fitzpatrick skin types.
New-onset diabetes (NODAT) after solid organ transplantation is an important clinical challenge associated to increased risk of cardiovascular (CV) events. In end-stage renal disease (ESRD) patients, the impact of arterial stiffness on all-cause and CV mortality has been clearly documented. Arterial stiffness has a pivotal role in the genesis of high blood pressure (SBP), increased left ventricular hypertrophy (LVH), and consequently CV mortality. Both LVH and arterial stiffness are independent determinants of CV disease in patients with ESRD. The aim of this study is to evaluate the relationship between post-transplant new-onset diabetes and arterial stiffness and left ventricular mass index (LVMI) in kidney transplant recipients.
The purpose of this research study is to test whether treatment with isosorbide mononitrate will improve left ventricular hypertrophy ("thickening") which puts people at risk for developing heart failure. Once it develops, heart failure is a very serious condition and thus it is important to find ways to prevent it from happening. The investigators have reasons to believe that dilating the blood vessels with this specific medication will improve the thickening of the heart, which increases the risk of heart failure.
Kidney patients on dialysis commonly die because of heart disease. One of the biggest problems in their hearts is that the muscle wall of the heart thickens. This makes it less efficient. We found in patients with mild kidney disease that a drug normally used to treat gout (allopurinol) had the remarkable side effect of being able to reduce this thickening of their heart wall. In this new study we aim to find out if this benefit of allopurinol also occurs in severe kidney patients i.e. those on regular dialysis. We also are trying to figure out the best dose of allopurinol to use. To do this we are planning a study where we will recruit patients with kidney disease who are on dialysis. The 1st phase of the trial will be to determine the best dose of allopurinol to use and the second phase will be to do a clinical trial where patients will be randomly allocated to either this optimum dose of allopurinol or a dummy medication (placebo) and will receive one year of treatment. They will have a special scan of the heart using an MRI machine to measure the extent of thickening of their heart muscle before they start on treatment and will have a further MRI scan when their one year treatment finishes. Phase 1- the dose finding study, will involve 10 patients who will have between 3 and 7 visits to the hospital scheduled around 4 to 17 dialysis sessions. The later study will involve up to 76 patients who will be asked to attend the hospital up to 8 times over a 13 month period.
Hypertrophic cardiomyopathy (HCM) is the most common monogenic heart disease and the most frequent cause of sudden cardiac death (SCD) in the young. It is characterized by unexplained left ventricular hypertrophy (LVH), diffuse and patchy fibrosis, and myofibrillar disarray. While the majority of patients remain asymptomatic, prognosis is poor in a subset who present with SCD or progress to heart failure (HF). Current methods to predict risk of these adverse events and to target therapy are limited. Current medical therapy does not protect against SCD, nor does it prevent development of HF. Therefore, the identification of novel risk markers would help develop therapeutic targets aimed at altering the phenotypic expression to impact the natural history, especially SCD and HF. Cardiovascular magnetic resonance (CMR) is emerging as a powerful tool for diagnosis and risk stratification in HCM including assessment of LV mass and pattern of hypertrophy. Late gadolinium enhancement by CMR is a marker of focal myocardial fibrosis which is thought to underlie the arrhythmogenic substrate as well as promote development of HF. The investigators hypothesize that HCM patients with a higher primary outcome event rate can be identified by novel CMR findings. The majority of cases of HCM are autosomal dominant and about 60% are caused by mutations in genes encoding cardiac sarcomeric proteins. However, the relationship between genetic mutation, disease phenotype, and clinical outcomes remains poorly understood. The investigators hypothesize that HCM patients with sarcomeric HCM mutations will have a higher primary outcome event rate and more marked myocardial pathology on CMR than those without. Furthermore, there may be a link between sarcomeric mutations and fibrosis, as mutation carriers with overt HCM as well as those without hypertrophy have elevated markers of collagen turnover. The investigators therefore hypothesize that serum biomarkers of collagen metabolism in HCM will predict outcomes. Thus, the Specific Aim is to develop a predictive model of cardiovascular outcomes in HCM by: 1) using exploratory data mining methods to identify demographic, clinical, and novel CMR, genetic and biomarker variables associated with the outcomes and 2) develop a score from the predictive model that can be used to assess risk given a patient's combination of risk factors, thus establishing the evidence base to enable clinical trial design to reduce morbidity and mortality in HCM in a cost-effective manner.
The primary objective of this study is to determine which treatment will be more effective to reduce left ventricular mass in hypertensive patients with left ventricular hypertrophy comparing aliskiren and eplerenone.
Cardiac allograft remodeling causes poor quality of life, allograft failure and increased mortality after heart transplantation. Risk factors for cardiac allograft remodeling and its progression are poorly defined and there is a need for effective interventions.This is a multi-factorial phenomenon, associated with various immunological and non-immunological factors. Animal studies suggest M-TOR inhibition attenuates cardiac allograft remodeling secondary to down-regulation of M-TOR downstream targets and increased autophagy. There is a paucity of data regarding effect of Sirolimus, a M-TOR inhibitor, on human heart remodeling. This aim of the proposal to identify the prevalence of cardiac allograft remodeling on current immunosuppressive strategies and determine risk factors for its development. It will also identify molecular pathways associated with cardiac allograft remodeling and determine the impact of Sirolimus on these pathways.
