RESUMEN
@#Objective To investigate the correlation of diabetes duration and coronary arterial pathological changes by coronary angiography in patients with coronary heart disease and type 2 diabetes mellitus.Methods 206 patients with coronary heart disease admitted into the hospital were divided into 4 groups:no diabetes(n=62),the duration of diabetes ≤5 years(n=41),>5～≤10 years(n=38)and >10～≤20 years(n=45).The interventional therapy history and type 1 diabetes mellitus were excluded.The pathologic changes of coronary artery evaluated by coronary angiography and the results among different groups were analyzed with the diabetes duration.Results There was no significant differences in the pathological changes of coronary artery between the group of no diabetes and the groups of ≤5 years duration and >5～≤10 years duration.However,the group of >10～≤20 years duration showed more serious pathologic changes of coronary artery than other groups including the multi-branch lesion,diffuse lesion and obstruct lesion(P<0.01).Conclusion Following the process of the diabetes,the coronary lesions in patients with type 2 diabetes mellitus tend to be more widespread and severe.
RESUMEN
This paper reported the results of balloon pulmonary valvuloplasty for 8 patients (single-balloon for 7 cases,double-balloon for 1 case).The meanpulmonary valve orifice in diameter (PVOD) was dilated from 8.4?2.2 preoperation to 16.4?1.5mm of postoperation,the systolic pressure in rightventricle (RV)was reduced from 16.9?5.3 to 9.1?3.8kPa,the pressure gradient from RV to pulmonary artery was reduced from 14.9?5.1 to 6.6?2.9 kPa,the cardiac index was increased from 3.2?0.3 to-5.1?0.7L/min m-2.The symptoms and heart murmur were nearly,subsided after treatment,the patients dischargd within 5 days after operation.PBPV is a nonoperative procedure with good efffect and.safety.
