Erratum to: J Zhejiang Univ-Sci B (Biomed & Biotechnol) 2010 11(8):631-633 doi:10.1631/jzus.B1001012. The online version of the original article can be found at http://dx.doi.org/10.1631/jzus.B1001012.
The original version of this article unfortunately contained a mistake. In the 6th paragraph of Section “4 Evaluation of PCI status in 2009”, the underlined data in “Online data showed that unstable angina, non-ST elevation myocardial infarction (NSTEMI), and ST elevation myocardial infarction (STEMI) occupied 54%, 29%, and 6% of the total PCI cases, respectively, 79% when added together.” were incorrect. The correct version is given below:
Online data showed that unstable angina, non-ST elevation myocardial infarction (NSTEMI), and ST elevation myocardial infarction (STEMI) occupied 54%, 6%, and 29% of the total PCI cases, respectively, 89% when added together.
