ABSTRACT
ObjectiveTo explore the diagnostic value of Tei index of right ventricle and serum level of NT-proBNP in patients with high-altitude heart disease (HAHD).MethodsRight ventricle Tei index and serum NT-proBN level were calculated and tested in 32 local healthy volunteers and 34 cases of HAHD patients hospitalized in our hospital in Golmud city (2808 meters above sea level) from 2008 to 2010,and a correlation study was conducted thereafter.ResultsThe pulmonary arterial systolic pressure and right ventricle Tei index,elevated significantly in HAHD patients compared with the control group [(86.61 vs 9.72)mm Hg(1 mm Hg=0.133 kPa) and(0.90 vs 0.33)respectively,P＜0.05].Patients diagnosed as mild pulmonary hypertension without alteration in cardiac structure showed higher pulmonary arterial systolic pressure and the Tei index compared with the control group [( 57.1 vs 9.72 )mm Hg and (0.78 vs 0.33 ) respectively,P ＜ 0.05 ].In addition,the level of serum NT-proBNP was significantly higher in HAHD group than that of control group [( 1246.8 ± 512.6) ng/L and (98.6 ± 21.7 ) ng/L respectively,P ＜ O.05 ].ConclusionRight ventricle Tei index and serum NT-proBNP level are sensitive indicators for right ventricular function and thus of favorable clinical significance for the diagnosis of HAHD.
ABSTRACT
Objective To observe through Color Doppler cordis Ultrasonographic image screening the characteristic changes on Chronic High Altitude Heart Diseases among Tibetans based on the data stand -ard set up by Qing Hai researchers .Methods Ninety-five subjects suffering from chronic high altitude diseases were checked by Color Doppler Ultrasonographic image devise .Datum were collected on the flowing rang measurement of the left ventricular ( LV) diameter, right ventricular diameter , left atrial ( LA) diame-ter, right atrial (RA), pulmonary aortic (PA) diameter.Index of the RV systolic and diastolic function were measured .The control group was fifth health subjects .Results There was transverse diameter of the RA and RV and also the diameter of the aotic and PA , showed highly significance in differences ( P 0.05 ) .The study group subjects LV systolic and diastolic function were declined , showed significant differences (0.01
