ABSTRACT
Objective: To analyze the atrial fibrillation(AF) and the burden of illness(BOI) led by AF, to scientifically recognize the current situation of management and treatment for AF, to provide scientific references for designing the AF prevention and control strategy for Chinese people and effectively improve the reasonable allocation of medical resources. Methods: The disability adjusted life years(DALY)was used to evaluate the BOI of AF. The method of population attributable risk percent-age was applied to estimate the treatment cost of AF cerebral apoplexy. Results: In China, the loss of DALY brought by AF was 4 599 687 yuan, which is higher than the loss of DALY brought by hypertensive heart disease(3 348 925 yuan)and close to the loss of DALY brought by diabetes(4 769 127 yuan). The DALY of group over 30 is 7.15/1000 person. Cerebral apoplexy is the main reason for the BOI of this disease. It is estimated that the annual treatment cost of AF cerebral apoplexy is 4.9 billion yuan(about 800 million dollars), 89%of treatment cost come from patients over 60 years old with AF and cerebral apoplexy. Conclusion: AF brought heavy BOI to Chinese society. Cerebral apoplexy is the main reason for the burden of this disease. The loss of DALY led by AF cerebral apoplexy is more than the BOI of many chronic disease in India and European countries. The diagnosis and treatment cautious of AF need to be strengthened. The correct treatment results in restoring sinus thymes, so as to decrease complication like cerebral apoplexy. That would be the target of AF treatment in future China.
ABSTRACT
Objective To observe the characteristics of the images of optical coherence tomography (OCT) performed on the patients with vitreomacular traction syndrome and its clinical significance. Methods The clinical data of 25 patients with vitreomacular traction syndrome diagnosed by OCT, fundus fluorescein angiography, and B-scan ultrasonography and confirmed by surgical treatment were retrospectively analyzed. The features of images of OCT in vitreomacular traction syndrome were observed. Results Five types were found in the images of OCT in the patients with vetreomacular traction syndrome. The main characteristic of the images of OCT in the patients with vitreomacular traction was the highly reflective band of the vitreous posterior cortex inservion at fovea. In 25 patients, vitreomacular traction associated with macular edema was found in 10, macular hole in 3, macular epiretinal membrane in 6, retinoschisis in 1, and retinal detachment in 5. Conclusion OCT is a potential powerful toll for detecting and monitoring vitreomacular traction syndrome.
