Congenital heart disease is one of the most common malformations in newborns. About 1% of newborns have cardiac malformations. Many need open heart surgery, which contributes substantially to pediatric mortality and morbidity. Recent advances in genetics suggest that many congenital heart defects are caused by mutation of genes. So far, half a dozen genes are found to be associated with congenital heart diseases, such as TBX5, NKX2.5, and GATA4, to name a few. In the near ...
Previous scientific research has found multiple genes that affect the risk for developing heart disease or complications during the treatment of heart disease. Less is currently known about how patients with heart disease may differ on the basis of other ailments they may have and how these other ailments may affect their treatment and prognosis. For this reason, researchers at the Mid America Heart Institute are conducting this research to find out how genes affect heart di...
Hypermetropia in school-aged children is a pathology which is very common and responds to treatments early. No studies have been found in the literature on the efficancy of the hypermetropia treatments with physiotherapy methods. In our study, it was aimed to investigate the effects of different eye exercises on hypermetropia defects in school age children aged 7-17 years and to determine whether exercise protocols have superiority against each other.
This study will evaluate how the cardiovascular system interacts with mechanical hearts to provide blood flow to the body during exercise. Two aims are proposed: 1) to determine the impact of a mechanical heart on exercise pressor reflexes in heart failure patients; and 2) to define the primary determinant(s) of exercise capacity in heart failure patients before and after device implantation.
The purpose of this study is to determine whether vigorous exercise training 4-5 days/week for one year in sedentary middle aged (ages 40-64) individuals at high risk for future development of heart failure will improve cardiac and vascular compliance to a degree equivalent to life-long exercisers and the sedentary young. To date, no effective therapy for heart failure with preserved ejection fraction (HFpEF) has been found; therefore prevention is critical and discovering nove...
Oxygen is routinely given to patients with common conditions such as COPD and heart failure. There is no evidence behind giving oxygen to patients specifically in heart failure due to a stiff heart. This study aims to explore the effect oxygen has on the ability of patients with chronic heart failure and the ability to exercise. Other common variables will be assessed such as heart rate and blood pressure to observe the response to varying concentrations of oxygen. The ...
Atrial fibrillation is a type of irregular heartbeat that is common after having heart surgery. There may be many different reasons why some people get atrial fibrillation after their heart surgery. These reasons may include that a person is older or that he/she is taking certain types of medications before surgery. Genes may also be a reason. Genes contain the material passed from parent to child that determines the make-up of the body and mind. For example, some genes cont...
The purpose of this research study is to better understand how skeletal muscle is affected by heart failure, and to determine how exercise interventions impact skeletal muscle and functional capacity. While many think of heart failure as a disease that only affects the heart, doctors now believe that it actually affects the whole body, including skeletal muscle, such as the muscles of your arms and legs. Therefore, while many people with heart failure develop weakness and reduc...
Exercise intolerance is a major burden for patients with complex congenital heart disease (CHD), significantly affecting their quality of life. Cardiopulmonary exercise testing provides a reliable tool both for assessing exercise capacity of CHD patients and for risk stratification and is becoming part of the routine clinical assessment of these patients. Exercise has an effect on the muscular, metabolic and circulatory systems. While exercise training has been widely studied i...
The primary purpose of this pilot study is to determine whether African Americans with mild Alzheimer's disease (AD) can be enrolled and retained in a 6-month aerobic exercise-training study.
Heart disease and stroke disproportionately affect African Americans in the United States. These conditions are likely caused by both environmental and genetic factors. This study will attempt to identify specific genes of African and European ancestral origins that may influence the development of heart disease in African Americans.
Regular exercise is known to produce significant health benefits and to reduce the risk of heart diseases, although how this benefit occurs is not well understood. White blood cells are known to be involved in triggering heart attacks, and which genes are switched on or off in white blood cells determines whether they have beneficial or harmful effects. Previous studies, and studies ongoing in our group, have demonstrated measurement of peripheral blood gene expression (which r...
This study will measure blood levels of endothelial progenitor cells (EPCs) and nitric oxide (NO) in patients with coronary artery disease (CAD) who are participating in a 3-month cardiac rehabilitation program at Suburban Hospital in Bethesda, MD. EPCs are a kind of stem cell produced by the bone marrow that can develop into cells found in arteries and in the heart and, therefore, can repair diseased vessels. The study will examine whether the EPCs are affected by exercise and...
The purpose of this study is to identify genes involved in depression. Specifically, the investigators will analyze some genes that may be related to whether or not a person responds to antidepressant medication. This project is part of basic scientific research to increase understanding of the role of genetic influences in psychological and mental processes involved in the response to treatment for depression.
Patients with CHF benefit from heart rate lowering, and the investigators have previously demonstrated that this does not adversely affect exercise tolerance. In a pacemaker population we also have shown that preventing heart rate lowering is detrimental in terms of symptoms and prognosis. The aim of the study is to therefore to establish whether heart rate limitation in patients with heart failure has a negative impact on exercise capacity. If the investigators establis...
This project deals with exercise in acute heart failure in three different groups (conventional medical treatment; exercise with non-invasive ventilation and exercise with placebo of non-invasive ventilation).
For implantation of developing conceptus, placental cells need to invade mother's uterus to access maternal blood supply in a control manner. We have found a combination of maternal immune genes (the KIR family) and fetal genes (HLA-C) strongly associated with pre-eclampsia where placenta does not implant adequately. The aim of this research is to investigate these two genes family in women suffering with recurrent miscarriages and find a possible link between them.
This is a multi-center, prospective evaluation of left ventricular recovery on conventional therapy in patients with the recent onset of dilated cardiomyopathy. In some subjects with this disorder, the heart will recover significantly over the first year, while others will be left with a chronically weak heart. The proteins that help the heart recover are encoded by genes, which can differ markedly between individuals. The goal of the current study is to determine whether vari...
The research project includes two components that assess exercise physiology parameters, cerebrovascular reserve, cognitive functions and cardiac function in coronary heart disease patients at rest, during an acute exercise, and after two different periodized training programs.
The purpose of this study is to determine if reducing blood flow to an exercising muscle during exercise training will enhance the training effect on that muscle in people who have limited exercise because of congestive heart failure
The purpose of this study is to learn if kinase, a protein found in the heart, contributes to thickening of the heart muscle in people with high blood pressure. A protein called myosin causes the heart to contract and relax. It is thought that kinase changes myosin to make it work better at different heart rates. This study will try to determine if, in some people with high blood pressure, the different forms of this protein cause changes in the heart. If the protein affect...
Up to half of all patients with clinical features of heart failure are found to have normal heart pumping function. Recently the investigators have shown that a drug called perhexiline markedly improved exercise capacity and symptoms in patients with heart failure associated with impaired cardiac pump function. In this proposal the investigators will assess whether perhexiline has beneficial effects in patients with heart failure and a normal heart pumping function.
The purpose of this is to develop and implement a pilot study that will demonstrate the ability to recruit, enroll, retain, conduct exercise training, and collect pre and post outcomes on the effect of exercise training on quality of life (QOL) and exercise capacity in patients with a diagnosis of heart failure with preserved ejection fraction (HFPEF).
Patients with heart failure cannot exercise as well as those who do not have heart failure, but the exercise dysfunction is not directly attributable to heart dysfunction. Rather, exercise is limited by problems with the skeletal muscles, the muscles in the arms and legs. In this study, the investigators are testing the hypothesis that high adrenaline levels lead to characteristic changes in skeletal muscles, and that interruption of these high adrenaline levels will lead to r...
The goal of this trial is to test the effect/benefit of a FDA approved blended pacemaker sensor which responds only by comparing physical activity, heart rate, and breathing rate; compared to the accelerometer pacemaker sensor which respond only by comparing physical activity and the heart rate in patients whose heart is unable increase its heart rate according to increase physical activity or demand (Chronotropic Incompetence). Only one pacemaker family will be used in this c...
