Abstract:
Objective To investigate the prevalence rate of heart valve calcification and its relativity with pathological changes and clinical pathogenic factors in elder patients at autopsy Methods Pathology data at autopsy of 1047 patients with age from 60 to 106 years in Beijing Hospital from November 1954 to March 2016 were collected.Cases of heart valve calcification verified at autopsy were retrospectively reviewed.The prevalence of heart valve calcification and its relativity with age,clinical disease and coronary atherosclerosis was investigated.Results Among 1047 autopsies,aortic valve calcification(AVC)was found in 15.2 ％ (n=159),mitral valve calcification(MVC)in 9.6 ％ (n=101),both AVC and MVC calcification in 5.4 ％ (n =57)and heart valve calcification in 19.4 ％ (n =203).The prevalence of heart valve calcification was 6.4％ (15/234)at age of 60-69,12.8％(37/289)at age of 70-79,22.5％(70/311)at age of 80-89 and 38.0％ (81/213) at age of 90-106 years,respectively(tendency x2 =82.523,P＜0.01).Calcification prevalence was significantly increased when complicated with coronary artery stenosis,hypertension,coronary artery disease (CAD),diabetes and chronic kidney disease (CKD).Multivariate regression analysis showed that age and CAD were independently risk factors for heart valve calcification(OR=1.066,95％ CI:1.048-1.086,P＜ 0.01;OR =2.238,95％ CI:1.396-3.589,P＜0.01,respectively),while hypertension,diabetes and CKD were not independent risk factors(OR =1.223,95％ CI:0.859-1.741,P＞ 0.05;OR =1.053,95％ CI:0.700-1.586,P ＞0.05;OR =0.924,95％ CI:0.610-1.399,P＞ 0.05,respectively).As compared with patients without heart valves calcification,patients with heart valve calcification had more increased risk for coronary atherosclerosis(OR =2.983,95a％CI:1.868-4.765,P＜0.01).Conclusions Prevalence of heart valve calcification is increased in elder patients with increasing age.Prevalence of heart valve calcification is higher in CAD patients than in non-CAD patients.And heart valve calcification is sigmficantly associated with coronary atherosclerosis.
