Official title
Vitamin D and Omega-3 Trial: Ancillary Study (VITAL-Echo) on the Impact of Vitamin D Supplementation on Cardiac Structure and Function
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The VITamin D and OmegA-3 TriaL (VITAL; NCT 01169259) is a randomized clinical trial in 20,000 U.S. men and women investigating whether taking daily dietary supplements of vitamin D3 (2000 IU) or fish oil (1 gram of omega-3 fatty acids) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. This ancillary study (VITAL-Echo) is being conducted among participants in VITAL and will examine whether vitamin D compared to placebo: (1) reduces left ventricular (LV) mass in elderly individuals as measured with 2-dimensional echocardiography and (2) improves LV systolic and diastolic function as measured with tissue Doppler echocardiography.
