Objective: To collect data on percutaneous coronary intervention (PCI) performed in mainland China.
Methods: Questionnaires on PCI were distributed to all hospitals capable of performing PCI through national society of cardiology. Data in calendar year 2008 were analyzed.
Results: (1) 182,312 PCI were performed in mainland China in 2008 (+26.02% vs. 2007), average PCI rate was 1.39 per 10,000 people. (2) PCI was performed in 1061 hospitals and 171.83 PCI was performed per hospital. Among them, there were 461 hospitals performed more than 100 PCI (+54.18% vs. 2007). (3) The number of PCI performed among provinces was positive correlated with local per capita gross domestic product (GDP, β = 0.06, P < 0.05) and the number of the hospitals performed more than 100 PCI per year (β = 434.23, P < 0.05), and negatively correlated with local population number (β = 0.49, P < 0.05). There were no correlation between the ratio of the hospitals performed more than 100 PCI per year (β = -2746.35, P > 0.05) and the ratio of people with medical insurance (β = -855.78, P > 0.05).
Conclusions: From 2005, PCI rose 23.87% per year in mainland China. There are significant differences among provinces on the development of PCI.
