ABSTRACT
Objective To analyse the rate of coincidence to suspected coronary artery disease (CAD) patient between positive exercise treadmill testing (TET) and coronary angiography (CAG) test.Method Two hundred and sixty-eight chest pain patients positive in TET were performed CAG test,coronary stenosis exceed 50% was diagnosed CAD. Results One hundred and seventy-six patients (65.67%) was diagnosed by CAG, 105 male and 71 female in them. Ninety-two (34.33%) patients was negative in CAG test. The false positive rate of TET between post-menopause patients (30.12%, 25/83 ) andmale patients (28.08%, 41/146) was no significant difference(P > 0.05 ); the difference of false positive rate between pro-menopause patients (66.67%, 26/39) and male patients (28.08% ,41/146) was statistical significance (P < 0.01 ). Conclusions The positive rate of CAG can be greatly improved by screening the chest pain patients though TET before CAG, if the positive in TET performed CAG only. TET false positive rate of pro-menopause female is significantly higher than post-menopause female or male.
ABSTRACT
Objective To investigate the effects of placing medical collagen sponge on the wound surface for severe rupture of liver.Methods In 132 patients with severe hepatic trauma , 68 cases were randomly enrolled in collgan spong treatment group, in which the hepatic wound was treated with collagen sponge,while the 64cases in control group were treated with commonly used gelatin sponge. Results The therapeutic results of collagan spong group were better than those of control group in the hemostatic time [(19.65?1.28)min vs (34.3?1.2)min], hemorrhagic volume [(301.57?56.8)mL vs (642.3?61.8)mL], abdominal cavity drainage volume[(380.45?12.34)mL vs (693.2?219.4)mL], recovery time of hepatic tissue [(30.30?6.42)d vs (62.1?7.2)d], postoperation complications (re-bleeding , and hepatobiliary leakage) [11.5% and 3.0% vs 6.3% and 9.5%], and hospital time stay [(24.01?4.89)d vs (35.8?5.9)d] (all with P
