Introduction: The goal of treatment of acute myocardial infarction is re-vascularation as soon as possible to minimize the myocardial. Messages of treatment: "Time is myocardium". Patients: 100 acute myocardial infarction cases, coronary intervention emergencies, including 80 cases of early intervention before 12 hours accounted for 80 percent. 15 intervention patients within 12 to 24 hours after onset of chest pain accounted for 15 percent and 5 patients received the intervention after 24 hours causes of late hospitalized, although the optimal medical therapy, but patients still in clinical chest pain. The door to balloon is 116.5 + or - 28.9 minutes. Conclusion: The implementation process of coronary intervention in the emergency treatment of acute myocardial infarction Viet-Tiep Hai Phong Hospital, shortening the time from onset of pain to re-vascularation contribute to effective treatment of acute myocardial infarction, reduced length of hospital stay, reduced complications and mortality, reduce cost and reduce the overload for the National Institute of Cardiovascular - Bach Mai Hospital.
