Active clinical trials for "Heart Diseases"

To examine the effect on health and disease of the work environment, psychological workload, control over work pacing and content, opportunity for use of skills, social support at work; the moderating effect on these relationships of social supports; and, the interaction between these psychosocial factors and other established risk factors in the etiology of chronic disease.

To develop a dietary intervention method that was capable of producing large sustained weight losses and was thus suitable for use in clinical trials related to obesity.

To study the relative effectiveness of teaching occupational nurses to conduct cholesterol screening, counseling and referral events (SCOREs) in their own worksites versus using an external organization to implement these programs. Also. to study the relative effectiveness of face-to-face behavior change counseling following the cholesterol measurement versus automated feedback of essentially the same individualized educational material.

To determine the effects of physical activity on blood pressure and body fat in children varying in ethnicity, gender, and health status.

To experimentally test methods to promote long-term smoking cessation in hospitalized patients.

To investigate whether a health education program, developed in partnership with the community and delivered by nurse supervised community health workers (CHWs), lowered high blood pressure (HBP) in inner city African American adults.

To study relationships among lipoprotein metabolism, hypertension, and hyperinsulinemia-insulin resistance in African American males and females. The study was part of a Collaborative Project on Minority Health which investigated the mechanisms by which insulin contributes to cardiovascular disease.

To investigate drug-gene interactions on the incidence of non-fatal myocardial infarction and stroke for hypertensive patients.

To continue an international collaborative study on hypertension in populations of West African origin.

To determine if selected circulating blood factors that reflect enhanced thrombogenesis are associated with an increased incidence of recurrent coronary events, including cardiac death or non-fatal myocardial infarction.
