| Objective:In this study,we retrospectively analyzed the clinical data of patients with acute myocardial infarction(AMI)who underwent coronary intervention therapy in a third Class A Hospital in Qiqihar City in 2017,to understand the demographic characteristics and clinical auxiliary examination indexes of different types of AMI patients.The methods of treatment,complications after coronary intervention,adverse cardiovascular events and death in hospital were designed to investigate the diagnosis and treatment of AMI and the recent prognosis of patients in a classified 3A hospital in this area.To reduce AMI mortality and improve the prognosis of patients in clinical work to provide a reference.Methods:A total of 572 hospitalized patients diagnosed with acute myocardial infarction and were treated with percutaneous coronary intervention were selected from January2017 to December 2017 of a classified 3A hospital in Qiqihaer city.The study collected general information,diagnosis and treatment,and recent prognosis of the subjects.Epidata 3.1 was used to establish the database and the above information was entered.IBM SPSS 24.0 statistical software was used to organize and analyze the above data.Results:1.Of the 572 patients,412(72.0%)were male and 160(28.0%)were female;50(8.7%)were in the< 45-year-old group,and 225(39.3%)were in the 45-59 age group,There were 242 patients(42.3%)in the 60-74 age group and 55 patients(9.6%)in the?75-year-old group.2.A total of 31 patients(5.4%)had complications associated with PCI during hospitalization,of which 3.3% had no reflow during PCI.The incidence of cardiovascular failure(MACCE)during hospitalization was 18.0%,including 15.6%in patients with heart failure;2.3% in patients with cardiac death.3.Of the 572 patients,369(64.5%)had ST-segment elevation myocardial infarction(STEMI)and 203(35.5%)had non-ST-segment elevation myocardial infarction(NSTEMI).Among patients with STEMI,those with high white blood cell count(58.0%),higher absolute neutrophils(70.5%),higher glucose(81.8%),higher creatine kinase(72.7%),and higher creatine kinase isoenzymes(44.5%)were higher than NSTEMI patients(34.0%,43.3%,68.5%,60.8%,and27.8%);the absolute neutrophil/lymphocyte(NLR)(P<0.01)and platelet count/ lymphocyte absolute value(PLR)(P=0.04)levels were higher in patients with STEMI than in patients with NSTEMI.4.In patients with STEMI,the incidence of complete occlusion of the vessel(59.0%),Segmental ventricular wall dyskinesia(63.7%),and ejection fraction(EF)abnormality(36.7%)was higher than that of NSTEMI patients(48.3%,37.3%,and22.9%),the difference was statistically significant(P <0.05).5.The proportion of emergency PCI patients(62.1%)and the use of temporary pacemakers(5.7%)was higher in STEMI patients than in NSTEMI patients(23.2%and 1.5%).10.4% of NSTEMI patients received ?3 coronary stent implantations,which was higher than STEMI patients(5.5%).6.The incidence of MACCE events during hospitalization for STEMI patients(21.4%)was higher than that of patients with NSTEMI(11.8%).Both the proportion of heart failure(17.9%)and malignant arrhythmia(6.0%)in STEMI patients was higher than that in NSTEMI patients(11.3% and 1.0%),and the difference was statistically significant(P<0.05).7.The proportion of in-hospital deaths in patients with AMI who had elevated white blood cell count,elevated neutrophil count,and high glucose and creatinine were 3.9%,3.7%,2.9%,and 6.9%,;Among patients the above indicators were normal or low,the proportion of in-hospital deaths was 0.7%,0.0%,0.0%,and 1.8%;the NLR level of death patients(9.51(4.76,15.00))was higher than that of non-dead patients(4.54(2.81,7.82))The differences were statistically significant(P=0.011).8.In-hospital mortality(19.4%)in patients with AMI who had surgery-related complications was higher than in patients without surgery-related complications(1.3%);In-hospital mortality(11.2%)in patients with AMI who experienced heart failure during hospitalization was higher than that in patients without heart failure(0.6%);The in-hospital mortality of patients with TIMI blood flow grading ? 2 after PCI was significantly higher than that of patients with TIMI grade 3 blood flow,the difference was statistically significant(P < 0.001).Conclusion1.In this study,patients with AMI were mainly concentrated in the 45-74 age group,mostly male and STEMI patients,and there are more STEMI in male patients and more NSTEMI in female patients.2.Compared with NSTEMI patients,STEMI patients with high inflammatory response and myocardial damage.In addition,in-hospital fatality rate is higher in patients with high inflammatory reaction.3.Compared with NSTEMI,patients with STEMI have severe stenosis,poor cardiac function,and are more likely to have MACCE events during hospitalization,especially heart failure.4.In-hospital fatality rate is higher in AMI patients with PCI-related complications and recurrent acute heart failure. |
