Atherosclerosis clinical trials at UCSF
3 in progress, 1 open to new patients

  • Mediators of Atherosclerosis in South Asians Living in America (MASALA) Social Network Study

    open to eligible people ages 40 years and up

    It has been argued that social relationships are important to health and well-being. This study will investigate links between social networks and cardiovascular disease risk factors in South Asians, the second fastest growing ethnic group in the US and one with disparate rates of coronary heart disease. Identifying and understanding the links between social networks and cardiovascular disease is key to the development and testing of family- and community-level prevention interventions for minorities.

  • Inflammation, Viral Replication, and Atherosclerosis in Treated HIV Infection

    Sorry, in progress, not accepting new patients

    This is a longitudinal observational study of HIV-infected patients and HIV-negative control patients that is being conducted to learn more about immunologic factors, inflammation, and cardiovascular risk in patients with HIV infection or in patients with autoimmune disease. The investigators plan to obtain measurement of carotid artery intima media thickness (IMT) using high resolution ultrasound as a noninvasive means for tracking atherosclerotic progression. The investigators will also measure lipid and lipoprotein levels, inflammatory markers, markers of Cytomegalovirus (CMV) infection, thrombotic markers, atherogenic lipoproteins, and markers of immune function. Immunophenotyping will be performed on freshly collected blood and analyzed by flow cytometry to identify activated T-cells, T-cell turnover, proportions of T-cells, and CMV function. HIV-infected patients will have CD4 count and HIV viral load measured in addition. Patients will undergo detailed clinical history including HIV disease, specific HIV medications, comorbid conditions, and health related behaviors. Physical exam and measurements will be obtained to assess for the presence of lipodystrophy. Patients will undergo study visits for ultrasound, blood draw, and interview at 4-12 month intervals for the next 3 years. Patients will also go assessment of endothelial function, endothelial progenitor cells, arterial stiffness as measured using pulse wave tonometry. To demonstrate the feasibility of a larger scale investigation of cardiac arrhythmia in HIV positive and negative patients with cardiac disease, the investigators will use 48-hour Holter monitor surveillance to monitor HIV-infected and uninfected patients with a history of myocardial infarction, systolic left ventricular dysfunction, and/or pulmonary artery hypertension for the presence of cardiac arrhythmia. The FDG PET scan (18F-fluorodeoxyglucose positron emission tomography-computed tomography) will be used to detect and quantify inflammation in the body.

  • Mediators of Atherosclerosis in South Asians Living in America

    Sorry, accepting new patients by invitation only

    South Asian (Indian, Pakistani, Bangladeshi, Nepali, and Sri Lankan) individuals have high rates of cardiovascular disease that is not explained by traditional cardiovascular risk factors. Though South Asians represent over one-quarter of the world's population, there are no longitudinal studies in this high-risk ethnic group. The investigators aim to establish a longitudinal study of South Asians at two United States centers to identify risk factors linked to subclinical atherosclerosis and incident cardiovascular disease. The purpose of this study is to understand the causes of heart disease and stroke in South Asians and compare these causes to those in other United States ethnic groups.
