ABSTRACT
Objective: To investigate the incidence of coutrast media iodixanol-induced delayed adverse reaction with the risk factors in general clinical practice. Methods: A total of 20,185 patients with contrast iodixanol were recruited from 95 medical centers in China. The risk factors for adverse drug reaction as hypertension, asthma, previous contrast reaction were assessed;the administrative processes as route, injection manner, lfow rate of injection, prior heating of iodixanol were monitored and the demographic information was documented. The immediate adverse reaction within 1 hour of media administration and the delayed adverse reaction from 1 hour to 7 days after administration were recorded. The risk factors for iodixanol-induced delayed adverse reaction were studied by singlevariate and multivariate logistic regression analysis. Results: The overall iodixanol-induced adverse reaction rate was 1.52%, of which the immediate reaction was 0.58%and delayed reaction was 0.97%. The major delayed reaction was mild and it mostly happened in skin (0.68%) including rash, pruritus and urticaria. Multivariate logistic regression analysis revealed that male gender (OR=0.71, P=0.036), age (OR=0.82, P=0.001), route of administration (OR=0.21, P<0.001), prior heating of iodixanol (OR=1.44, P=0.036), lfow rate of injection (OR=1.28, P=0.001) and previous contrast reaction (OR=16.04, P<0.001) were the independent risk factors for delayed adverse reactions.
ABSTRACT
Objective To study the relationship between ankle-brachial index and all cause mortality and cardiovascular disease mortality in female Chinese patients with atherosclerotic risk factors.Methods A total of 1744 female patients with no less than two atherosclerotic risk factors were enrolled from several hospitals in Shanghai and Beijing.Baseline exams were measured.All the participants were followed up 13 months.Results The patients with PAD were significantly older than those without PAD[(72.42?9.158)years vs(65.89?10.366)years,P
