Ws. Aronow et al., ASSOCIATION OF MITRAL ANNULAR CALCIUM WITH NEW THROMBOEMBOLIC STROKE AT 44-MONTH FOLLOW-UP OF 2,148 PERSONS, MEAN AGE 81 YEARS, The American journal of cardiology, 81(1), 1998, pp. 105
We investigated in a prospective study of 2,148 persons (mean age 81 y
ears), the association between mitral annular calcium and new thromboe
mbolic stroke at 44-month follow-up. Independent risk factors for new
thromboembolic stroke were prior stroke (risk ratio 2.4), mitral annul
ar calcium (risk ratio 2.6), atrial fibrillation (risk ratio 3.0), and
male gender (risk ratio 1.6).
