Active clinical trials for "Heart Diseases"

The purpose of this study is to determine if restoring normal metabolic function in patients with either type I or type II diabetes can improve the impact of the consequences of diabetic complications on heart disease in diabetic patients. Patients are treated once a week with pulsatile intravenous insulin therapy mimicking normal insulin secretion. A diabetic cardiac disease quality of life questionnaire is completed prior to the start of the treatment and monthly thereafter with detailed analysis performed to measure progress and outcomes. A carotid ultrasound and echocardiogram are performed at baseline and every six months to monitor progress.

To determine if 16-64 slice multidetector CT (MDCT) can replace the invasive procedure in patients scheduled for coronary angiography in order to exclude the presence of CAD

We hope to learn more about why certain people have higher levels of the 5-LO protein and whether taking fish oil supplements gives such individuals greater protection than others against cardiovascular disease. The 5-LO protein is important in the development of heart disease because it converts a type of oil from meat into a compound that can cause inflammation in blood vessels. This inflammation is a major cause of heart disease. Researchers think that people with higher levels of a protein called 5-LO in their white blood cells may have a healthier response to using fish oil supplements than do people with lower levels of this protein.

Intermittent pneumatic compression (IPC) of the lower extremities is a well-established technique for preventing deep vein thrombosis (DVT) and for treating venous stasis. IPC will be done in the home for 3 divided hours every day for 4 weeks. Lab tests, brachial ultrasound and MRI testing will be performed at baseline and after 4 weeks of daily IPC therapy. See detailed description for increase in healthy control subjects.

The aim of the present study is to assess the effect of a high intake of industrially produced trans fatty acids for 16 weeks on abdominal obesity and risk markers of type 2 diabetes and heart disease in healthy, moderately overweight, postmenopausal women.

The primary objective of the FIT Heart Study was to test the effectiveness of a hospital-based standardized screening and educational intervention targeted to family members of patients hospitalized with CVD, to increase adherence to CVD prevention guidelines.

This study will investigate the separate and combined effects of aerobic and resistance training on cardiovascular risk factors in overweight men and women with mild to moderate dyslipidemia.

In spite of declining trend coronary heart disease (CHD) is still a leading cause of morbidity and mortality. Many years of epidemiological research have identified several risk factors for CHD. The main causes are physical inactivity and inappropriate diet (mediated through high blood pressure, high cholesterol and fatness) and smoking. So far intervention studies on lifestyle factors have shown disappointing results, most probably due to insufficient interventions and methodology. Inter99 is a randomized non-pharmacological intervention study comprising 61,301 persons representing a well-defined population. About 13,000 are invited for a health examination and assessment of risk for CHD. Those at high risk are offered lifestyle intervention in three waves over a five year period. A priori the group is divided into a high intensive and low intensive intervention group. The remaining 48.285 individuals serve as control. After five years all individuals who attended the base-line examination are re-invited to assess the effect of the intervention on intermediate end-points as lifestyle, absolute risk of CHD and biological risk factors. The total cohort (61.301) is followed through central registers to evaluate the effect of the intervention on use of the health care system and the long term effect on incidence of CHD. The status for the project is that the four waves of intervention have been performed, the last follow-up was in March 2006. Data collection finalized with 10 years follow-up via Central National Registries and a questionnaire. No further follow-up is scheduled for the main purposes of the study. Analyses as regard the primary effect (on incidence of cardiovascular diseases) and secondary effect (on incidence of type 2 diabetes) are on-going. Analyses for a large number of spin off project are on-going. More than 25 Ph.d. studies and more than 200 peer-review publication have so far been produced.

Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. Using very low electrical pulses that travel across the inside of the chest cavity, thoracic fluid status monitoring (OptiVol™) can measure the level of resistance to the electrical pulses, which indicates the level of fluid in the chest. The purpose of this study is to collect information related to fluid build up in the chest of subjects with heart failure.

The purpose of this study is to determine the long-term safety and effectiveness of exercise training for individuals with congestive heart failure (CHF).
