Wang L, Yang Y, Zhou Y,

To investigate the prevalence of TRA and TRI in China in the years 2006 and 2007.

About 47wQbNPTDJp9hMYdvogK2hAUiHsGeiybwaWe36bwtRQ3UTpYV7YuZ8FV5j9nauFCWwcjM6dTzpL5s2N79Rp5unwdMvc8ZKU and 2008.

Data was collected from 163 and 111 hospitals all over China in the year 2006 and 2007, respectively. A total of 108,658 CAG and 45,176 PCI cases in 2006 and 115,124 CAG and 48,379 PCI cases in 2007 were enrolled in the study. There were more TRA and TRI in 2007 than 2006 (TRA, 60.23% vs. 47wQbNPTDJp9hMYdvogK2hAUiHsGeiybwaWe36bwtRQ3UTpYV7YuZ8FV5j9nauFCWwcjM6dTzpL5s2N79Rp5unwdMvc8ZKU catheter types during TRA in 2006 and 2007 (Judkin’s, 47.62% vs. 40.52%; MP, 41.23% vs. 47wQbNPTDJp9hMYdvogK2hAUiHsGeiybwaWe36bwtRQ3UTpYV7YuZ8FV5j9nauFCWwcjM6dTzpL5s2N79Rp5unwdMvc8ZKU. 93.13% in 2007). Unfractionated heparin (UFH) was the major anticoagulant during TRA and TRI (88.76% in 2006 vs. 99.10% in 2007,). Nitroglycerine (NTG) was the major vasodilator to prevent radial artery spasm (75.80% in 2006 vs. 92.79% in 2007).

Transradial approach has become the primary access of CAG and PCI in China.
