We investigated in a prospective study of 2,148 persons (mean age 81 years), the association between mitral annular calcium and new thromboembolic stroke at 44-month follow-up. Independent risk factors for new thromboembolic stroke were prior stroke (risk ratio 2.4), mitral annular calcium (risk ratio 2.6), atrial fibrillation (risk ratio 3.0), and male gender (risk ratio 1.6).
