Filter by:The consequence of aortic valve stenosis (AVS) is increased pressure load on the left ventricle which causes left ventricular (LV) hypertrophy, and myocardial stretch will cause activation of cardiac peptides and activation of the renin angiotensin aldosterone system (RAAS). The consequence of LV hypertrophy is increased chamber-stiffness and delayed active LV relaxation which initially will cause diastolic and later systolic dysfunction. In heart failure (HF) and ischemic heart disease the degree of diastolic dysfunction has been demonstrated to correlate with functional class, neurohormonal activation and prognosis which also recently have been suggested for AVS. With longstanding elevated filling pressures the left atrium (LA) will dilate. Only limited data are available on the degree and importance of LA dilatation in AVS. When apparent, symptoms of HF in AVS are associated with high mortality rates. If LV systolic dysfunction also is present prognosis will deteriorate further. In these cases aorta valve replacement (AVR) is recommended. AVR will normalize pressure overload and thereby decreases LV hypertrophy. Previously it was believed that in time LV hypertrophy regressed towards normal and even normalized. Recent studies however have demonstrated that LV hypertrophy regression mainly happens during the first year after AVR, and little subsequent changes are seen during the remaining 10 years. Furthermore, patients that experience most regression of hypertrophy have more favourable outcome and better functional class than patients with less regression of hypertrophy. Thus absence of reverse remodelling is associated with poor outcome after AVR. Importantly the regression of LV hypertrophy is closely paralleled by decreasing RAAS hyperactivity. RAAS hyperactivity may be attenuated pharmacologically with angiotensin II receptor blockers (ARB) which in systemic hypertension with LV hypertrophy has been associated with reverse remodelling. The hypothesis is that in patients undergoing AVR for symptomatic AVS, 12 months post operative blockade of the angiotensin II receptor will accelerate LV and LA reverse remodelling, reduce filling pressures and suppress neurohormonal activation compared with conventional therapy. This will lead to improved exercise tolerance and due to improved left atrial function reducing the risk of atrial arrythmias.
The purpose of this study is to identify the patients seen in our practice who are seen with Hypertrophic Myopathy diagnosis in order to better understand the presenting characteristics of their disease, the diagnostic testing to determine the diagnosis, the methods used to follow the disease progression and management practices used in caring for these patients. The objectives of this data review will be an analysis to determine if there is a methodology that will foster improved diagnostic speed and accuracy, and determine the best management practices based on outcomes in these patients.
The purpose of this study is to examine the effect of dietary cholesterol administered as whole egg or egg white (control)on muscle mass gain with resistance training in a young old population of men and women (age 50-69). It is hypothesized that dietary cholesterol will be significantly associated to muscle mass gain.
Uroxatral (alfuzosin) may not only help BPH symptoms but may also improve sexual function in males with BPH and ED.
Supine feeding position is associated with serous otitis media. The hypothesis is that supine feeding is associated with recurrent otitis media, tonsillar and adenoid hypertrophy and recurrent pneumonia secondary to recurrent aspiration.
The aim of this study is the identification of familial congenital arrhythmogenic disorders and their clinical follow-up.
To compare the efficacy and safety of aliskiren in combination with losartan compared to losartan on the regression of the increased size of the left ventricle in overweight patients with high blood pressure.
Pyloric stenosis is a condition that develops in infants and that leads to an obstruction of the channel going out of the stomach. This study is being performed to determine if there is an advantage to the laparoscopic approach or the open approach for the surgical correction of the enlarged pylorus.
Left ventricular hypertrophy (LVH) predicts mortality at start of dialysis. Prevention of of LVH is important. It is not known whether secondary hyperparathyroidism might induce LVH. In the present study patients are randomised to 1.25 dihydroxycholecalciferol or no treatment to study the effect on LVH.
Despite the growing evidence showing that breast hypertrophy is associated with reduced Health-Related Quality of Life (HRQL) and that reduction mammoplasty has a significant positive impact on HRQL, there are unresolved issues that need to be addressed. These include our ability to measure quantitatively the change that occurs after reduction and the ongoing restriction or denials of third party payments based on body mass index (BMI). The primary purpose of this study is to assess and measure the HRQL experienced by breast reduction patients using four reliable and validated HRQL measures. Fifty-two consecutive patients with the diagnosis of breast hypertrophy were invited to participate in this prospective study. Participants completed the Health Utilities Index Mark 2 (HUI2) and Mark 3 (HUI3) and the Breast Reduction Assessment Value and Outcomes (BRAVO) instruments (the Short Form 36, the Multidimensional Body-Self Rating Questionnaire Appearance Assessment, and the Breast Related Symptom Questionnaire) at one week and one day pre-surgery and one, six, and 12 months post-surgery.
