老年人心脏钙化综合征是常见的,属于动脉粥样硬化的范畴。该综合征最多见的部位是冠状动脉外膜,冠状动脉内的钙沉积多在内膜形成斑块,而非冠状动脉的中层,这标志着冠状动脉粥样硬化的形成。在低年龄者冠状动脉外膜有钙质沉积,不仅提示动脉粥样硬化斑的存在,而且几乎均存在该部位严重的冠状动脉管腔狭窄。老年人心脏钙沉积其次常见的部位是二尖瓣环周围。“二尖瓣环钙化”(MAC)这一命名似欠妥当,因为通常肉眼看不见二尖瓣环部位的钙沉积,实际上钙沉积的部位在二尖瓣后叶下和与其平行的左心室内膜之间。二尖瓣后叶有C形环状面附着于二尖瓣
Elderly heart calcification syndrome is common and belongs to the category of atherosclerosis. The most common site of this syndrome is the adventitia of the coronary arteries, where calcium deposits in the coronary arteries are more plaques in the intima than in the middle coronary arteries, marking the formation of coronary atherosclerosis. Coronary adventitia in younger age with calcium deposits, not only prompted the presence of atherosclerotic plaque, and almost all of this area there is severe coronary artery stenosis. The second most common site of calcium deposition in the elderly is the mitral valve annulus. The term “mitral annulus calcification” (MAC) seems to be inappropriate because calcium deposits at the mitral annulus are not normally visible to the naked eye, and indeed the site of calcium deposition is below the posterior mitral valve and parallel to the left ventricle Between the inner membrane. Posterior mitral c-ring surface attached to the mitral valve
