title: [Survey of medical care resources of acute myocardial infarction in different regions and levels of hospitals in China].
abstract: OBJECTIVE
  To investigate the medical care resources of acute myocardial infarction (AMI) in Chinese hospitals of different regions and levels.
  
  
  METHODS
  We selected 115 hospitals in China, including 61 northern hospitals, 54 southern hospitals, 52 eastern hospitals, 26 central hospitals, 37 western hospitals, 79 tertiary hospitals, 36 secondary hospitals, 34 pro vincial-level hospitals, 46 prefectural-level hospitals and 35 county hospitals. From November 2012 to August 2013, we sent questionnaire to the cardiologists in each hospital, to collect related information.
  
  
  RESULTS
  (1) The number of AMI admitted each year of northern hospital was more than the number of southern hospital (220 (120, 400) cases vs. 220 (80, 350) cases, P=0.033), while number of coronary care unit (CCU), thrombolytic therapy, percutaneous coronary intervention (PCI), primary PCI and coronary artery bypass grafting (CABG) were similar (all P> 0.05). (2) The number of AMI admitted each year of eastern, central and western hospital was 295(150, 501) cases, 175(75, 300) cases and 170(50, 250) cases respectively(P=0.007), with no significant difference among them for setting CCU, carrying out thrombolytic therapy, PCI, primary PCI and CABG (all P>0.05). (3) The total number of the in-patient beds and AMI admitted each year of tertiary hospitals were significantly higher than that in the secondary hospitals(104(70, 152)vs. 47(30, 52), P<0.001) and (300(200, 460)cases vs.80(47, 135)cases, P<0.001) respectively. There was a significant difference between tertiary and secondary hospitals for the number of CCU (97.5% (77/79)and 75.0%(27/36)), PCI (98.7%(78/79)and 27.8%(10/36)), primary PCI (96.2%(76/79)and 22.2%(8/36)), CABG (81.0%(64/79)and 11.1%(4/36)), intra-aortic balloon pump (IABP) (91.1%(72/79) and 13.9%(5/36)) respectively (all P<0.001). (4) There were obvious differences among provincial-level, prefectural-level and country-level hospitals for the admitted AMI patient numbers annually which was 400(250, 600), 232(100, 380)and 80(50, 162)cases, CCU proportion which was 100 %(34/34), 95.7%(44/46) and 74.3%(26/35), thrombolytic therapy proportion which was 88.2%(30/34), 100%(46/46)and 91.4%(32/35), PCI proportion which was 100%(34/34), 89.1%(41/46)and 37.1%(13/35), primary PCI proportion which was 100%(34/34), 84.8%(39/46)and 31.4%(11/35), CABG proportion which was 97.1%(33/34), 67.4%(31/46) and 11.4%(4/35)respectively (P<0.01 or 0.05) .
  
  
  CONCLUSIONS
  Different regional hospitals have no significant difference in number of CCU and reperfusion therapies, while there is a big difference on medical care resources of AMI between different-level hospitals, which may affect the diagnosis and treatment effect of patients with AMI.
