Objective To assess the safety and efficacy of the new Cordis coronary stent in the Chinese population.Patients A total of 32 patients recieved 34 Cordis stents (target lesions of 32) from July to December 1995 in our hospital. Vessel distribution was 18 LAD (53%), 8 Lcx (23.5%) and 8 RCA (23.5%).Methods All cases were studies retrospectively. The coronary lesions were predilated with standard balloon angioplasty followed by implantation of Cordis stents. The reference diameter of the vessels and the minimal luminal diameters (both before and after stent implantation) were measured by quantitative angiography. All patients were followed up at mean peroid of 3 months with regards to their symptoms and angiographic follow-up at 6 month's time were carried out in 8 patients.Results Delivery success was achieved in all lesions except 1 unsuccessful delivery due to failure to negotiate an acute angle of a left main vessel to LAD. Average MLD post stenting was satisfactory (0.53±0.36 mm vs 3.32±0.34 mm) compared to reference diameter of 3.13±0.4 mm. There was 1 patient with complication of subacute stent thrombosis. Another patient died 5 weeks later from non-ischaemic end stage heart failure secondary to severe aortic regurgitation. Loop seperations occurred in 2 stents (5.8%) during deployment.Conclusions The Cordis stent implantation is efficacious with high angiographic success rate. The strong radiopacity facilitates precise positioning of the stent in the target lesions. Our experience in the Chinese population is favourable. Stent deformity was possible. For smaller stents of 3 mm, higher pressure of balloon inflation for deployment followed by adequate anticoagulation is recommended. Further studies are required to investigate the long term restenosis rate.

Objectives:
This study aimed to investigate the relationships of foot and leg symptoms, structure, and function with functional limitations and osteoarthritis (OA).
Methods:
We included 1253 participants (mean age 58.1 years) from the Hong Kong Osteoporosis Study who completed an examination on foot posture, function, pain, and presence of deformities such as hallux valgus and varus knee. Using logistic regression, we estimated cross-sectional associations of each foot and knee problem with functional outcomes (slow walking speed, self-reported falls, and functional limitations) and OA. Through linkage to electronic health records, we further examined their associations with incident OA over 8 years using Cox models. All models were adjusted for age, sex, and body mass index.
Results:
The prevalence of hallux valgus, foot pain, and varus knee were 33.1%, 35.1%, and 25.8%, respectively.Planus foot posture was associated with varus knee, and pronated foot function was associated with hallux valgus. Of the assessed foot problems, only foot pain showed significant associations with functional outcomes, including functional limitations and recurrent falls. Foot pain was also associated with prevalent OA at baseline but not incident OA. Meanwhile, we observed a 3-times increased risk of incident OA associated with varus knee (95% CI = 1.48–6.10), and this association was particularly seen in older adults, women, and obese individuals.
Conclusions
In community-dwelling Chinese adults, foot pain, but not the reported foot deformities, is associated with functional limitations and falls, while varus knee is associated with incident OA.
