A Prospective Evaluation of Health Services Outcomes & Emerging

Status Active, not recruiting

Clinical Trial Summary

The primary aim of the proposed research is to examine the relationship of lifestyle changes to new dietary, biomedical, and cellular parameters among new enrollees entering the "Dr. Dean Ornish Program for Reversing Heart Disease program" at 5 selected sites. Specifically, the investigators will add assessments of emerging cardiac risk factors (e.g., high sensitivity C-reactive protein [hsCRP], fibrinogen, lipoprotein(a) [Lp(a)], small, dense LDL, apolipoprotein B [apoB], apolipoprotein A-I [apo A1], the apoB/apoA1 ratio, homocysteine [Hcy], B-type natriuretic peptide [BNP], oxidized LDL, fasting insulin and waist-to-hip ratio [WHR]), protective and pathogenic dietary markers (e.g., folate, carotenoids, trans fatty acids), and measures of social support and cognitive functioning to the already existing assessment variables in the Multisite Cardiac Lifestyle Intervention Program (MCLIP).

Hypothesis 1: Participation in the lifestyle program will not only be associated with favorable changes in standard coronary risk factors and quality of life, but also with improvements in emerging cardiac risk factors [hsCRP, Hcy, BNP, fibrinogen, Lp(a), small, dense LDL, apoB, apoA1, oxidized LDL, fasting insulin, and abdominal obesity] and psychosocial well-being (i.e., social support, and cognitive functioning).

Hypothesis 2: High intake of emerging protective dietary factors and low intake of emerging pathogenic dietary factors will be associated with improvements in both standard and emerging cardiac risk factors (e.g. Hcy, oxidized LDL).

Hypothesis 3: Degree of adherence to the lifestyle change program will be associated with differential improvement in standard coronary risk factors, emerging risk factors, cellular aging, and psychosocial variables.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
