Active clinical trials for "Heart Diseases"

To determine the prevalence and longitudinal course of sleep apnea among men and women and to examine the associations of apnea, oxygen desaturation, snoring, high blood pressure, and other biomedical correlates.

To conduct a surveillance study of congestive heart failure (CHF).

To examine some of the psychosocial predictors of poor outcome among revascularized coronary artery disease patients.

To identify early childhood determinants of eating and exercise behaviors that relate to cardiovascular disease.

To study mechanisms of excess coronary ischemia secondary to alterations in autoregulation and arteriolar vasoreactivity in Black Americans with hypertension, varying degree of left ventricular hypertrophy, and angiographically normal or mildly diseased coronary arteries.

To estimate the relative risks of acute myocardial infarction (MI) and of stroke in postmenopausal users of estrogen/progestogen (E/P) combinations and to estimate the relative risks of MI and of stroke in users of estrogen alone.

To compare rates of coronary heart disease (CHD), cancer, total mortality and exercise injuries in 68,000 runners and 68,000 walkers during four years of surveillance

This retrospective study aimed to evaluate the demographic characteristics, clinical conditions in term of physical examination findings), functional status, and laboratory results of patients with thalassemia minor (TM) and breast cancer (BC) in order to identify any differences between the group with BC only. Available data as anticancer treatment, comorbidities, weight and height will be combined to report body mass index (BMI) in kg/m2, systolic and diastolic blood pressure, heart rate, ECG, transthoracic echocardiography, blood count, lipid panels, glucose, kidney function tests, (N terminal) NT-proBNP, troponins, handgrip assessments, functional status were extracted from patients files and hospital electronic archives.

Babies can be born with heart problems and sometimes need a heart surgery to fix the heart problem. Heart surgery can cause swelling from the build-up of extra fluid. Swelling can make it harder for babies to breath and has to be treated with medicine called diuretics. Swelling is hard to measure in babies, so it can be hard to know how much diuretic they need to treat the swelling. The investigators are looking for a better way to measure swelling in babies who have had heart surgery. Ultrasound uses sound waves to take pictures of the inside of the body. Ultrasound is used to take pictures of babies before they are born and to take pictures of their heart after they are born. New ultrasound software has been made from a company called MuscleSound that can quickly measure the amount of swelling in adults, usually in less than 2 minutes. This software has not yet been used to measure swelling in kids. This study plans to learn more about swelling in babies and will try to measure swelling in babies before and after heart surgery with the new ultrasound software. The study will also make the same measurements in babies who do not have heart disease to compare to babies having heart surgery.

Clinical ultrasound has become essential in emergency medicine. The guidelines are to use of echocardiography in specific contexts: dyspnea, hypotension or chest pain. The evaluation of left ventricle ejection fraction (LVEF) is one of the basic objectives of echocardiography. The reference assessment in emergency medicine is visual assessment. It suffers from poor inter-observer reproducibility. Pocket ultrasound scanners seem to meet the constraints of point-of-care ultrasound. A new tool is available on a pocket ultrasound device: the automatic evaluation of LVEF. Its interest could be to have a better inter-observer reproducibility than visual evaluation.
