There were no operation-related death;one died of respiratory failure 14 days after operation while staying in hospital; there were more respiratory complications in the conventional coronary artery bypass grafting group (CCABG) than in the OPCABG group; and the PaO2/FiO2 in the CCABG group was higher than that in the OPCABG group during operation because of CPB, but lower than that in the OPCABG group 6-12 hours after operation. OPCABG seemed more suitable than CCABG for coronary artery disease patients with chronic obstructive pulmonary disease due to less damage to their oxygen-exchange capability and the fewer respiratory complications.展开更多

RESULTS: One to three days after the onset of SARS, the major clinical symptoms were fever (in 88.14% of patients), fatigue, headache, myalgia, arthralgia (25-36%), etc. The counts of WBC (in 22.56% of patients) lymphocyte (70.25%)and CD3, CD4, CD8 positive T cells (70%) decreased. From 4-7 d, the unspecific symptoms became weak; however, the rates of low respiratory tract symptoms, such as cough (24.18%), sputum production (14.26%), chest distress (21.04%) and shortness of breath (9.23%) increased, so did the abnormal rates on chest radiograph or CT. The low counts of WBC, lymphocyte and CD3, CD4, CD8 positiveT cells touched bottom. From 8 to 16 d, the patients presented progressive cough (29.96%), sputum production (13.09%), chest distress (29.96%) and shortness of breath (35.34%). All patients had infiltrates on chest radiograph or CT, some even with multi-infiltrates. Two weeks later, patients' respiratory symptoms started to alleviate, the infiltrates on the lung began to absorb gradually, the counts of WBC, lymphocyte and CD3, CD4, CD8 positive T cells were restored to normality.CONCLUSION: The data reported here provide evidence that the course of SARS could be divided into four stages, namely the initial stage, progressive stage, fastigium and convalescent stage.展开更多

The age range of patients was 21-50, with a mean of 38.5 years. Ten out of 12 were females, 1 patient had candia failure due to almost incessant VT while the rest had normal left ventricular function. Twelve pts had VT arising from the right ventricle; of those, 9 were from the outflow truct, 2 from the RV apex, and 1 from the RV inflow. In all pts the diagnostic study and therapeutic RFA were combined in a single procedure. Pacemapping and local activition time were used to guide the site of RFA in pts with VT arising from the right ventricle. RFA was successful in 11 of the 12 pts(91 % ). Number of RF applications were 1 -27, mean 9. 6;fluo- roscopy time were 4-75, mean 26. 9 minutes. RFA for idiopathic RV has a high success rate. This mode of treatment should be considered as a nonpharmacological curative treatment for symptomatic pts.展开更多
