Filter by:Main research question: Is vertical scar reduction mammoplasty superior when compared to inferior pedicle reduction mammoplasty in terms of patient quality of life and cost-effectiveness? Why is this research important?: There is on-going controversy among plastic surgeons as to the superiority of one technique (vertical scar mammoplasty versus inferior pedicle reduction mammoplasty) over the other in terms of patient health related quality of life and health care resource utilization. What is being studied?: We are studying (comparing) two surgical procedures for breast reduction mammoplasty (vertical scar mammoplasty versus inferior pedicle reduction mammoplasty).
To investigate the effect of pulse width on the treatment response of keloidal and hypertrophic sternotomy scars to a 595-nm pulsed dye laser
Left ventricular hypertrophy (LVH) increases the risk of cardiovascular morbidity and mortality in patients with high blood pressure, compared to those without LVH. Reduction of left ventricular mass (LVM) with antihypertensive agents is associated with improved clinical outcome. This study will evaluate the effects of amlodipine/benazepril in reducing LVM in patients with high risk hypertension.
This study is designed to compare the effects of COREG MR (carvedilol modified release formulation) to atenolol on indices of left ventricular dimensions when added to standardized angiotensin converting enzyme (ACE) inhibition, and to the effect of ACE inhibition alone. Subjects with LVH (left ventricular hypertrophy) and hypertension will be studied. The primary endpoint will be the change in left ventricular mass index (LVMI) characterized by magnetic resonance imaging (MRI) following 12 months of treatment. Secondary endpoints include the change in LV (left ventricular) mass, LV wall thickness, diastolic left ventricular filling parameters, and left ventricular ejection fraction by echocardiographic methods at Treatment Month 12. Composite outcomes and individual event data will also be evaluated by treatment group.
This study will examine how heart stiffness and a weak atrium affect exercise capacity and symptoms in patients with hypertrophic cardiomyopathy (HCM). The atrium is the booster pumping chamber of the heart that helps the ventricle (main pumping chamber), to fill properly. HCM is an inherited disease in which the ventricle becomes thickened and, in some patients, stiff. The stiffness makes it difficult for the ventricle to fill and empty, causing breathing difficulty, fatigue, and reduced exercise capacity. Scar formation and a weakened atrium can cause the heart to stiffen. Information gained from this study may guide doctors in prescribing medicines to reduce scarring or improve atrial function. Patients 21 years of age and older with hypertrophic cardiomyopathy may be eligible for this study. Candidates will be screened with a medical history and physical examination, electrocardiogram (EKG), blood tests, Holter monitor, and echocardiogram. A Holter monitor is a device about the size of a Walkman that is connected to three wires that are attached to the chest. It is worn for 24 hours to provide continuous monitoring of heart rhythm. An echocardiogram uses a small probe that emits sound waves to produce images of the heart. The probe is moved across the chest and the reflection of the sound waves from the chambers of the heart produce images showing the heart's thickness and function. Participants will undergo the following tests and procedures over 3 days: - Physical examination and echocardiogram. - Intravenous cannula insertion: A plastic tube is inserted into an arm vein for collecting blood samples to measure substances that the heart and circulatory system release at rest and during exercise. - Impedance cardiography: A small current of electricity is passed across the chest and electrodes similar to those used for an EKG test are placed to measure blood flow in the area of the current. - Pulmonary artery catheterization: A catheter (plastic tube) is inserted into a vein either in the arm, under the collarbone, or in the neck and advanced to the right atrium and ventricle. The catheter remains in place during the echocardiogram tilt and bicycle exercise tests (see below). - Echocardiogram tilt test: The patient lies flat on a table. After a few minutes, the table is tilted so that the patient's head is just above his or her feet for a short while, then is positioned flat again, and then tilted so the feet are just above the head. Echocardiographic measurements and blood samples are taken at intervals to examine heart function during changes in posture. - Echocardiogram bicycle stress test: The patient exercises for as long as possible on a bicycle-like machine while lying on his or her back. Echocardiographic measurements and blood samples are taken at intervals during the test. - Treadmill stress test: The patient runs for as long as possible on a treadmill that increases in difficulty. The patient wears a facemask or mouthpiece through which small amounts of gases are added in order to measure the ability of the heart and lung to increase their effectiveness with exercise. - Digoxin loading: Only patients who demonstrate limited exercise capacity and for whom digoxin is not a risk will undergo this procedure. A medicine that makes the heart contract more strongly, digoxin is used to treat certain heart abnormalities. Patients are given doses of either digoxin or placebo (a look-alike injection with no active ingredient) at 4-hour intervals over a 24-hour period and then repeat the tilt test and the bicycle and treadmill exercise tests
How high blood pressure in hemodialysis patients should be diagnosed and treated using medications or without medications is the purpose of this study.
The purpose of this study is to evaluate the safety and efficacy of ALT-711 in the treatment of isolated systolic hypertension in a formal study in patients with left ventricular hypertrophy. Eligible patients will be randomized to double-blind treatment once daily for 6 months with oral ALT-711 (210 mg) or placebo.
To use magnetic resonance imaging to identify subclinical atherosclerosis and left ventricular hypertrophy in the Framingham Heart Study cohort.
Multi-center, prospective randomized dosing and safety research study. A maximum of 150 men will be enrolled in the study. Qualifying patients will receive one of three possible doses of the study drug. Symptoms will be evaluated before treatment, and then 1-week, 1-month, 3-months, and 6-months following treatment.
This study will test the feasibility of a modified procedure for treating obstructive hypertrophic cardiomyopathy (OHC). Patients with OHC have a thickening of the heart muscle that obstructs blood flow out of the heart, causing breathlessness, chest pain, palpitations, tiredness, lightheadedness, and fainting. The current treatment for OHC is a procedure called alcohol septal ablation (also percutaneous transluminal septal ablation, or PTSA), which involves injecting a small amount of alcohol into a tiny artery that supplies the part of muscle causing blood flow obstruction. The success of PTSA is limited, however, by problems of heart anatomy and the ability to find the appropriate artery to inject. Modifying the procedure by injecting the alcohol through the wall of the lower right chamber of the heart may improve its safety and effectiveness. The new technique requires positioning a catheter (a flexible tube) into the appropriate area of the heart. This study will test the ability to accurately guide the catheter to that area. Patients with OHC 18 years of age and older who are scheduled to have a cardiac catheterization may be eligible for this study. At the end of the catheterization procedure, participants will undergo intra-cardiac echocardiographic imaging. For this test, one of the catheters placed in the femoral artery (at the top of the leg) for cardiac catheterization will be substituted for a larger one. Through this catheter, a special catheter will be introduced and advanced to the heart to provide images. This pilot feasibility study does not involve injection of alcohol.
