Angiographic verifi cation and clinical predictors of anatomical variations of radial artery / 中国介入心脏病学杂志

ABSTRACT

Objective To discuss the incidence and clinical predictor factors of anatomical variation of radial arteries among patients in the XingJing province of China. Methods A total of 1731 patients who underwent transradial coronary intervention for the first time during the period of Jan.2016-June.2016 in the People‵s Hospital of Xin jiang Uyghur Autonomous Region were enrolled in this study. All relevant basic information and related medical history were recorded in detail.Right radial artery angiography was performed in all patients, According to the definition of radial artery variation, the patients were decided into the radial artery variation group and the normal radial artery group. Single factor and multiple factors logistic regression analysis were performed to evaluate the predictive value of variables factors in radial artery variations. Results The incidence of radial artery variation was 4.97%(86/1731).The incidence of radial artery spasm in the radial artery variation group33.72%(29/86),and 2.74% (45/1645) in the normal radial artery group (P<0.001).The failure rate of coronary intervanton by right radial artery in the radial artery variation group was 26.74%(23/86)and 1.51%(25/1645)in the normal radial artery group(P<0.001).The overall success rate of coronary intervention through right radial artery approach was 97.23%(1683/1731).Female gender,short statue、low body weight,history hyperlipidemia,smoking,drinking rabbit,occupation as farmer were found to be associated with the existence of radial artery variation (all P < 0.05).Diabetes,body mass index,hyperlipidemia and ethnicity were not associated with the existence of radial artery variation (all P >0.05). Multivariate logistic regression analysis showed age, gender, farmer occupation, hyperlipidemia were associated with the occurrence of radial artery variation. Increased in age by every 10 years would bring a 0.264 fold increase in risk of radial artery variation(OR 1.264,95%CI 1.006-1.587, P=0.044)and the risk of radial artery variation in females was 3.999 times to males(OR 3.999, 95%CI 2.241-7.136,P<0.001).The risk of radial artery variation in patients with hyperlipidemia was 1.776 times to patients without hyperlipidemia(OR 1.776,95%CI 1.011-3.122,P=0.046)and the risk of radial artery variation in farmers was 2.188 times higher than others(OR 2.188,95%CI 1.238-3.867, P=0.007). Conclusions For people in Xinjiang in China,anatomical variation of radial artery was uncommon. Advanced age, female gender, short states, low body weight, hyperlipidemia, smoking, drinking and farmer occupation were associated with the occurrence of radial artery variation. Multivariates logistic regression analysis showed advanced age, female gender, hyperlipidemia, farmers were associated whit the presence of radial artery variation. These factors have predictive value for the existence of radial artery variation.
