Active clinical trials for "Heart Diseases"

The aim of this study is to assess cardiac rate and respiratory responses and rhythm after workplace exposure to combustion particulates. A repeated measurement study is being performed on acute boilermakers (apprentices and journeymen). A stratified analysis is then done on those with and without chronic bronchitis, after adjustment for relevant covariates.

To examine the role of reduced vagal control of heart rate in the increased risk of cardiac mortality associated with anxiety in a population with established coronary artery disease (CAD). A second objective is to determine whether the effects of anxiety are independent of the effects of depression.

To conduct extended analysis of the Postmenopausal Estrogen/Progestins Intervention PEPI trial database to address questions related to cardiovascular disease risk factor response and the possible determinants of this response.

To investigate the relationship of birth weight and childhood blood pressure.

To test whether novel cardiovascular risk factors are related to the presence and development of atherosclerosis and macrovascular events in Type 2 diabetes mellitus and to determine whether intensive glucose lowering therapy will reduce the levels of these cardiovascular risk factors.

To develop and evaluate a nutrition education program to reduce cardiovascular disease risk in persons with low literacy skills.

To utilize a community-based approach to nutrition education in an urban African American community.

To examine the effects of ethnicity, socioeconomic status (SES) and behavior in overweight adults.

To investigate the prevalence and prognostic value of subclinical atherosclerosis in the Pittsburgh SHEP cohort and a cohort of normal controls.

To determine whether an impairment of myocardial perfusion reserve is an early indicator of coronary artery disease.
