ABSTRACT
Objective To investigate the related factors of early angina after acute myocardial infarction,and to provide basis for the disease prevention and control.Methods 1 32 cases with acute myocardial infarction were selected.The clinical data were collected.The occurrence rate of early angina pectoris after acute myocardial infarc-tion,and clinical characteristics were analyzed.The related factors of acute myocardial infarction angina were explored.Results The incidence rate of early angina pectoris after acute myocardial infarction was 29.55%.Within 7 days after acute myocardial infarction occurred angina,the highest rate for 64.1 0%,followed by 7 -1 4 days in the occurrence of angina pectoris,28.21 %.34 cases were the original location of myocardial infarction ischemia and 5 cases were the far part of ischemia,21 cases showed ST segment elevation,1 8 cases showed ST lack blood group downward.Anterior wall,inferior wall infarction composite,successful thrombolytic therapy recanalization,myocardial infarction before episodes of angina pectoris,history of hypertension,heart function classification more than or equal to grade III in patients with acute myocardial infarction occurred after the proportion of early angina pectoris were signifi-cantly higher (all P <0.05).Conclusion Anterior wall,inferior wall infarction composite,successful thrombolytic therapy recanalization,myocardial infarction before episodes of angina pectoris,history of hypertension and cardiac functional grading more than or equal to grade III are related to early angina pectoris after acute myocardial infarction. We should actively take measures aimed at early prevention and treatment of early angina pectoris after acute myocar-dial infarction to avoid illness aggravating,improve the patients'prognosis.
