Active clinical trials for "Heart Diseases"

The aim of this prospective study is to investigate the prevalence of coronary artery disease using computed tomography with family history of premature coronary heart disease

To assess the need of respiratory gated radiotherapy in left sided breast cancer patients.

Rheumatic heart disease remains a major health problem in developing countries. It is the most important sequel of rheumatic fever and occurs in about 30% of patients with rheumatic fever.Rheumatic heart disease presents with different degrees of pancarditis and associated valve failure. Involvement of the mitral leaflets can cause mitral regurgitation (MR) or stenosis and eventually can lead to heart failure. Mitral repair or replacement is therefore recommended before left ventricular (LV) dysfunction develops. Study Objectives/Specific Aims Overall Goal: To determine the benefit the patient with pulmonary hypertension will get from mitral valve replacement as regard function improvement and remodeling of the right ventricle. Objective1: Identify risk factors that are predictive of outcomes.(Type and severity of Mitral valve pathology , severity of pulmonary hypertension, tricuspid regurge, preoperative RV dysfunction) Objective2: Determine the value of management strategies (Mitral valve replacement in pulmonary hypertension i.e. : decrease RV pressure overload and enhance RV remodeling) Objective3: Assessment of the outcomes clinically & Echocardiographically : postoperative results during hospital stay and follow up (short term up to 3 months).

It is unclear to what extent systemic fluid overload has an impact on T1-mapping results by cardiovascular mangetic resonance imaging. In this study, patients will undergo body composition monitoring assessing systemic fluid overload and T1-mapping using MOLLI by cardiovacular magnetic resonance imaging in order to investigate a possible association with each other.

Hypertension is a serious threat to human health and a major global economic burden.Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure.Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension.Therefore, this study intend to use two-dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction the change of the global and local cardiac work, and the influence of aterosclerosis in thes patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function.To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases.

Children born with congenital heart problems face numerous physical, developmental, and social challenges. Complications in pregnancy have potential to impair brain development, leading a smaller brain volume and less mature brain even in babies born at full term. As the brain is less mature, it may be more susceptible to oxygen deprivation and other forms of brain injury. Urgent surgery is often required in the first few weeks of life to improve functioning of the heart, but this surgery also carries a risk of additional brain injuries. The aim of this study is to provide a better understanding of factors associated with the development of brain injury in neonates undergoing heart surgery in the first year or life. The short-term aim of this study is to provide data to help our team to develop advanced monitoring software that can be used to guide perfusion of the brain during surgery with a view to preventing surgery-related brain injury. The mid-term goal of the study is to identify risk factors associated with brain injury and inflammation around the time of surgery, through using MRI and taking blood samples. A longer term aim of this study is to be able to follow the children as they develop to see if any problems develop later in life. In this study, we will ask parents to complete two brief questionnaires when their infant reaches 2 years of age. Overall, this study aims to improve our understanding of the causes of brain injury in patients born with congenital heart problems. The data provided by this study will help us to develop new tools for monitoring brain perfusion during surgery.

The objective of this study is to research the relationship between maternal exposure to environmental factors and fetal congenital heart disease in a community-based case-control study.

This research will focus on young women between the ages of 18-38 who underwent a heart operation and their life experiences. This research will focus on these life events and the paradigm of these women being raised as "heart sick," and consequently lacking self-esteem (Frigiola, Bull, & Wray, 2014; Hickey et al., 2012). Most qualitative studies focusing on the quality of life compare men and women, completely ignoring women's body image and the experience of womanhood (Hickey et al., 2012; Hövels-Gürich et al., 2007; Sarikouch, et al., 2013). This study aims to focus on women's stories about their life experiences and the influence of surgery(ies) on their daily life using an the qualitative phenomenological approach.
