简要总结
Studies have shown that people with rheumatoid arthritis (RA) have a higher rate of heart disease than people that do not have RA. we believe this is caused by the inflammation produced by RA.
详细描述
Aim 1: We want to study people with RA to see if we can detect very early changes in their heart muscle and compare these results to people who do not have RA.

结局指标
主要结局
Left Ventricular Mass Indexed to BSA, g/m^2
时间窗: one scan, cross sectional comparison
Left Ventricular Mass (LVM) is known to increase in proportion to overall body size and differs by gender. To assess an individual's risk for a cardiovascular event based on LVM,an adjustment for the patient's body size should be done. LVM in grams was divided by body surface area in meters squared, to adjust for body size. Body surface area was calculated by square root (height (cm) X weight (kg)/3600).
次要结局
- Left Atrium Size, mm(one scan, cross sectional comparison)
