ABSTRACT
Objective To study hyperbaric oxygen on left ventricular ejection fraction preserved by the influence of left ventricular remodeling in patients with heart failure. Methods A total of 110 patients with heart failure and normal ejection fraction were randomly allocated into the control group (n=55) and the HBO group (n=55). The control group were given the routine therapy, the HBO group were treated with hyperbaric oxygen on the basis of conventional drug. The application of color doppler ultrasound before and after treatment for 3 months left ventricular structure indicators. Results Left ventricular structure indicators were significantly decreased (LVDd、IVSD、LVPWD、LVMI)(P<0.01). Compared with the control group the difference was statistically significant (P<0.05). Follow-up of 3 months, The treatment group composite cardiovascular events was fewer than the control group and had significant difference (P<0.05). Conclusion Hyperbaric oxygen therapy can significantly improve left ventricular ejection fraction preserved by heart failure of left ventricular diastolic and systolic function and reverse left ventricular remodeling,And can reduce the happening of cardiovascular events.
ABSTRACT
Objective To study the clinical valne of color Doppler ultrasound for the diagnosis of primary ureteral carcinoma. Methods 15 patients with pathologically confirmed primary ureteral carcinoma by color Doppler ultrasound were retrospectively analyzed. Results 15 patients with lesions above the ureter and renal pelvis and varying degrees of expansion,water, of which 11 cases of solid mass within the probe and ureter. Color Doppler showed lesions could be detected, and dot, stripe and dendritic arterial blood flow signal, resistance index (RI) 0. 58 ～ 0. 67.Conclusion Color Doppler ultrasound screening of primary ureteral carcinoma has important diagnostic value, can increase the rate of preoperative diagnosis,and can provide reference for clinical staging.
ABSTRACT
Objective To study the effects of hyperbaric oxygen on the diastolic heart failure in hypertensive patients. Methods 60 hypertensive patients with diastolic heart failure were randomly divided into treatment group and control group. Conventional therapies were given to patients of both groups. In addition, hyperbaric oxygen therapy was applied to those of treatment group. After 3 months, Doppler ultrasound recordings were obtained from all patients to determine the left ventricular diastolic function. Results The indexes of left ventricular diastolic function were im-proved after treatment in both groups(P < 0.01) ,and treatment group was better than control group(P < 0. 05). Conclusion For hypertensive patients with diastolic heart failure, hyperbaric oxygen can improve heart diastolic function.
ABSTRACT
Objective To study the effects of enhanced external counterpulsation (EECP) on the diastolic heart failure in hypertensive patients.Methods 104 hypertensive patients with diastolic heart failure were randomly divided into treatment group and control group,52 patients were given 36 hours of treatment EECP.After 6 months,Doppler ultrasound recordings were obtained from all patients to determine the left ventrlcular diastolic function.Resuits Left ventricular diastolic function index and the left ventrich mass weight index (LVMI) wero impmved after treatment in both groups(P＜0.01),and EECP treated group was better than control group(P＜0.05).Conduslon For hypertensive patients with diastolic heart failure,EECP could not only improve heart diastolic function,but also reverse reconstruction of the left ventricuhr.
ABSTRACT
Objective To investigate the echocardiographic determination of uremic patients with myocardial weight and in the evaluation of cardiac function in patients with uremia heart the significance of the damage.Methods 70 cases of uremic patients and 30 normal physical were examined by routine echocardiography,cardiac measurements through the menu of uremic patients with myocardial weight and heart function.The patient group and the normal control group were compared.Results 70 patients with uremic echocardiography resuits of the analysis showed,respectively,12.8%and 84.3%existence of left ventricular systolic dysfunction and left ventricular diastolic dysfunction.left ventricular mass in patients with significant increase are significantly higher than those in healthy control group(P＜0.01).Conclusion Uremic patients left ventricular diastolic dysfunction and left ventricular hypertrophy most of echocardiography is the detection of cardiac damage in patients with uremia practical,sensitive,non-invasive examination will be able to clinical diagnosis and treatment provide guidance in the clinical widely used.
ABSTRACT
Objective Delve into the applied value of CDFI to diagnose deep vein thrombosis(DVT)in lower limbs.Methods Analyze the diagnosis of 65 chronic cases of DVT with a two-dimensional CDFI,and contrast it with the operation,X-ray angiography and clinical features.Results 36 acute cases of DVT;29 chronic cases of DVT;38 cases of lesion in left lower hmb(58.5%);21 in right lower limb(32.3%);and 6 in both lower limbs(9.2%).In the chronic cases,11 have formed collateral branch circulation.Conclusion CDFI has a safe and rapid effect on vein illness in lower limbs and can show the state of blood streams and the condition around the veins.It Can explain the unknown swollen in limbs.Realizing DVT in early stage has good value for its occurring,expanding and treating.
