Effect Of Chest Pain Center Construction On Emergency PCI Diagnosis And Treatment In Patients With Acute ST-segment Elevation Myocardial Infarction

Objectives To investigate the changes of emergency PCI diagnosis and treatment in patients with acute ST-segment elevation myocardial infarction(STEMI)before and after the construction of Chest Pain Center in Zun hua City People's Hospital(upper secondclass hospital),evaluate the influence on the diagnosis and treatment in STEMI patients by the establishment of chest pain center.Method 103 cases of STEMI patients under PCI before the construction of Chest Pain Center were recruited as the control group and 120 cases of STEMI patients under PCI after the construction were recruited as the observation group.The length of hospital stay,the costs in hospital,the proportion of emergency PCI in the STEMI,the way to the hospital,the time of FMC2 B and D2 B,The standard rates of FMC2 B time and D2 B time,the ratio of the major adverse cardiovascular events and major complications were compared between the two groups.the indexes after 1 year follow-up :the major adverse cardiovascular events and cardiac rehabilitation indexes(standardized drug use and drug taking compliance,whether to quit smoking or not,whether to exercise rehabilitation or not)are compared between the two groups.Results FMC2 B time and D2 B time(176.3±79.4min and 67.8±38.4min respectively)in the observation group were shorter than those(235.6±76.9min and 117.4±48.0min respectively)in the control group(P<0.05).The standard rates of FMC2 B time and D2 B time(31.8% vs 20.3%;77.5%vs 49.5%)were higher than those in the control group(P<0.05).The proportion of emergency PCI(44.4%vs 34.9%)and 120 calling(30% vs11.7%)increased(P<0.05),the major adverse cardiovascular events(recurrent angina pectoris,recurrent acute myocardial infarction,heart failure,cardiac death,malignant arrhythmia)and major complications(no reflow of coronary,,coronary dissection,acute coronary occlusion,stent thrombosis,massive haemorrhage)in the observation group was lower than in the control group(P<0.05).the indexes after 1 year follow-up :the major adverse cardiovascular events(recurrent angina pectoris,recurrent acute myocardial infarction,heart failure,cardiac death)in the observation group was lower than in the control group(P<0.05),cardiac rehabilitation indexes(evidence-based drug use and drug taking compliance,whether to quit smoking or not,whether to exercise rehabilitation or not)improved significantly(P<0.05)and the length of stay and hospitalization expenses reduced in the observation group(P<0.05).Conclusion The construction of standardized chest pain center may effectively shortens the rescue time of emergency PCI patients with STEMI,improves the treatment effect,and reduces the length of stay and hospitalization expenses.The construction of chest pain center in hospitals of grade two and above two is worthy of further clinical promotion.
