| Objective: To discuss the clinical features of acute myocardial infarction(AMI)and coronary artery lesions in young people in Inner Mongolia.Methods : From October 2016 to October 2020,we retrospectively analyzed 201 young patients who were diagnosed with AMI through coronary angiography from the Inner Mongolia People’s Hospital,including120 cases of Han nationality(Three generations of parents were Han nationality and were not intermarried with other ethnic groups),81 Mongolian cases(parents were both Mongolian nationality and were not intermarried with other nationalities).At the same period,we selected 155 young patients who were excluded the diagnosis of coronary heart disease through coronary angiography,including 105 cases of Han nationality and 50 cases of Mongolian cases.By collecting and analyzing their smoking history,clinical data drinking history,family history of coronary heart disease,hypertension,history of diabetes,BMI,biochemical,coronary artery disease,etc.,to obtain the clinical features of young AMI in Inner Mongolia.Results:(1)Compared with the youth control group,the young AMI group combined with hypertension and diabetes were significantly higher than the youth control group.The biochemical indicators included WBC,NE,TC,TG,LDL-C,Lp(a),NT-pro BNP,Hb A1 c and CRP were significantly higher than the youth control group,and the difference was statistically significant(P < 0.05).(2)Binary Logistic regression results show that smoking history(OR=2.240),hypertension(OR=2.496),diabetes(OR=3.714),family history of coronary heart disease(OR=6.969)are independent risk factors of acute myocardial infarction.(3)Through the comparison of various indicators of AMI patients between young Han and young Mongolians,we found that the differences in drinking history,BMI,and Lp(a)were statistically significant(P<0.05),and Han nationality’s proportion of drinking history,BMI,Lp(a)were all significantly higher than young Mongolians.(4)There was no significant difference in the number of diseased vessels between the two ethnic groups(P>0.05),and the proportion of single-vessel disease in both ethnic groups was the highest.(5)There was no statistically significant difference between the blood vessels of criminals of the two ethnic groups(P>0.05).(6)Compared the classification of coronary artery disease between the two ethnic groups,the difference was statistically significant(P<0.05),and type A was more common in Han nationality,and type B was more common in Mongolian nationality.(7)There was no statistically significant difference in the incidence of thrombosis and collateral circulation between the two ethnic groups(P>0.05).There was a statistically significant difference in Gensini score between the two groups(P<0.05),and the Han nationality was significantly higher than the Mongolian nationality.Conclusion:(1)Young AMI patients with smoking history,hypertension,diabetes,family history of coronary heart disease,inflammatory indicators,and abnormal blood lipid levels are higher than those of young normal patients.The independent risk factors are smoking history,hypertension history,diabetes history,and family history of coronary heart disease.(2)The proportion of drinking history,BMI and Lpa of young Mongolian AMI patients are higher than that of Han young AMI patients.(3)Coronary angiography of young AMI patients of Han nationality and young Mongolian AMI patients are more common in single-vessel lesions,and the diseased vessels are successively LAD,RCA,LCX,LM.Three-vessel lesions,diffuse lesions and collateral circulation are less common,and the limitation coronary artery lesions are more common. |
