Although current clinical guidelines stipulate that patients with hypertrophic cardiomyopathy should not partake in high intensity exercise (HIE) or competitive sport due to safety concerns, there is no clear evidence to support this notion. In fact, two exercise training interventions in this population indicates that regular moderate to vigorous intensity exercise is efficacious for improving exercise capacity and cardiorespiratory fitness, and does not increase arrhythmia burden or adverse events. Moreover, moderate intensity exercise and HIE training significantly increases cardiorespiratory fitness in patients with cardiac disease. Such improvements are associated with substantial reductions in cardiovascular mortality and might outweigh the risk of adverse events in patients with hypertrophic cardiomyopathy (HCM). Having a genetic cardiomyopathy does not grant immunity against lifestyle related cardiometabolic diseases and inactivity is rife in HCM patients likely due to misinformation/education. It is therefore paramount to further explore the benefits of regular moderate intensity exercise and HIE in patients with HCM for proper therapeutic management of the condition.
Aortic stenosis is the most common heart valve disease requiring intervention in high income countries. It is characterised by progressive valvular thickening, and restriction as well is hypertrophy and fibrosis of the left ventricle in response to pressure overload. The pathological processes in the left ventricle that ultimately result in heart failure and death are incompletely understood. Further elucidation of these processes and how they correlate with novel blood biomarkers may help us design new treatments and optimise the timing of surgical intervention. In brief, recruited patients with severe aortic stenosis and scheduled to undergo valve replacement surgery will be invited for some simple tests (blood sampling, ECG, echocardiogram). A septal myocardial biopsy will be taken at the time of surgery and the disease valve retained. These will be examined histologically and pathological changes compared with results obtained from ECG, echocardiogram and blood tests.
The frequency of cardiac amyloidosis among patients presenting with a so-called left ventricular hypertrophy remains unknown. This problem is especially relevant in the Caribbean's, where an amyloidosis-prone mutation of transthyretin gene might be frequent.
The purpose of this pivotal investigation is to evaluate the efficacy and safety of the Cutera enlighten multi-wavelength 532 nm and 1064 nm Nd:YAG picosecond pulse duration laser and an investigational micro-lens array (MLA) handpiece attachment for improvement of acne scars.
Differentiating hypertrophic cardiomyopathy (HCM) from hypertensive heart disease (HHD) unavoidably encounters diagnostic challenges especially in patient of suspected HCM with history of hypertension. Diverse and overlapping forms of HCM can often lead to ambiguity when diagnosis is based on a single genetic or morphological index. The investigators have deduced a integrated formula based on cardiac magnetic resonance (CMR) imaging and established a differentiating flow-chart between HCM and HHD, the investigators aim to identify their method in the current multi-center trial.
This is a randomized, controlled, within-patient, single-blinded, pilot study that will evaluate the impact of laser treatment on burn HSc relative to self-matched control scars. The studied primary outcomes of treatment are scar pliability, thickness, vascularity, pain, itch and patient satisfaction.
Assess the efficacy of fimasartan on left ventricular hypertrophy in hypertensive patients
Obstructive sleep apnea syndrome (OSA) is the most frequent sleep disorder characterized by excessive decrease in muscle tone of the soft palate, the tongue and the posterior pharyngeal wall. It leads to airway collapse. In cases of decreased airway passage hypoventilation (hypopnea) occurs while periodic lack of airflow is called apnea. An obstructive sleep apnea syndrome is recognized as an independent cardiovascular risk factor. OSA is very common in patients with resistant hypertension. RAH is diagnosed when blood pressure remains elevated despite simultaneous use of 3 antihypertensive agents from different groups of drugs at optimal to maximum doses, including a diuretic. In patients with OSA frequent episodes of hypoxemia during sleep result in the repeated activation of the sympathetic nervous system. What is more, the episodes of respiratory disorders increases in levels of aldosterone serum concentration with following sodium and water retention and elevation of blood pressure finally. An increased aldosterone level also stimulates synthesis of collagen, promotes stiffening of the arterial wall, myocardial fibrosis with heart muscle remodeling and takes part in development of left ventricular hypertrophy (LVH) - common complication of hypertensive patients with OSA. Several studies, including the Sleep Heart Health Study have confirmed that severe OSA is associated with high prevalence of concentric hypertrophy through sympathetic activation and vasoconstriction. Eplerenone is a selective mineralocorticoid receptor inhibitor. It has no affinity for glucocorticoid, progesterone and androgen receptors and therefore has lower risk of side effects. Eplerenone lowers blood pressure and inhibits heart muscle fibrosis. The hypotensive effect is caused by reduction of fluid retention. Probably, in patients with OSA, a reduction of fluid accumulation especially at the level of the neck may contribute to lowering the resistance in the upper respiratory tract and in that way it may help to decrease the severity of OSA. As LVH remains a strong and independent predictor of total mortality and death from cardiovascular causes, in this study we want to assess whether the addition of Eplerenone to a standard antihypertensive therapy will favorably change left ventricular geometry. We also want to check if the addition the Eplerenone to a standard antihypertensive therapy could be an effective therapeutic option for patients with OSA and RAH.
Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated. The investigators will perform a comparative trial testing etelcalcetide vs. alfacalcidol treatment on top of conventional HPT therapy for 12 months. A total of 62 hemodialysis patients with sHPT and LVH will be enrolled in the study. After a washout of all calcimimetic and vitamin D treatment, subjects will be randomized at 1:1 ratio to either etelcalcetide or alfacalcidol. The participants will undergo cardiac imaging consisting of cardiac resonance imaging (cMRI) and strain echocardiography before and at baseline and one year. Etelcalcetide or alfacalcidol will be administered intravenously three times per week following chronic hemodialysis treatment. The primary end point will be a change in left ventricular mass index (LVMI) measured in g/m2. As secondary end points the changes in left atrial diameter (LAD), cardiac fibrosis, wall motion abnormalities and left ventricular function, changes in serum FGF 23 and soluble Klotho levels as well as changes in proBNP as well as pre- and postdialysis troponin T (TnT) levels will be determined. Additionally a quantitative analysis of the treatment influence on the individual metabolites of the renin-angiotensin-aldosterone system (RAAS) will be performed using mass spectrometry ("RAAS fingerprint").
