The Creation

SummaryAnalysis of electrocardiograms tape-recorded from patients admitted to hospital with acute myocardial infarction revealed that the pattern of ventricular extrasystolic activity was not significantly different among those who subsequently developed ventricular fibrillation and those who did not. Episodes of ventricular fibrillation occurred predominantly within 4 hours from the start of infarction. Patients were 3 times less likely to survive an episode of ventricular fibrillation if they also had left ventricular failure than if this feature was absent. Management of episodes of ventricular fibrillation was compared in patients before and after the creation of a specially staffed and equipped coronary care unit. The success of electric shock as a treatment for ventricular fibrillation was similar before and after the creation of the coronary care unit. An attempt was made to determine which features in the management of ventricular fibrillation in this and in previously published series were associated with patient survival.

Abstract Background Cardiac troponin (cTn) is the preferred biomarker for the diagnosis of acute myocardial infarction (AMI). Octogenarians who presented cTn positive AMI are not usually recruited in clinical trials. Therefore, their clinical characteristics and prognosis are rarely investigated. Objective To study the characteristics and prognosis in octogenarians who presented cTn positive AMI. Methods and results The Japanese registry of acute Myocardial INfarction diagnosed by Universal dEfiniTion (J-MINUET) is a prospective and multicenter registry. A total of 3,283 consecutive AMI patients who were diagnosed by cTn-based criteria were included. The patients were divided into non-octogenarians (n=2,593) and octogenarians (n=690). Compared with non- octogenarians, octogenarians showed significantly lower incidence of diabetes mellitus (37.6% and 31.9%, p=0.006) and dyslipidemia (53.6% and 45.6%, p<0.001), and significantly higher incidence of hypertension (64.1% and 75.3%, p<0.001) and chronic kidney disease (38.7% and 68.7%, p<0.001). Octogenarians showed significantly longer onset to door time (p<0.001) and longer door to device time (p<0.001). Though, compared with non-octogenarians, octogenarians showed lower peak CK (2,506 and 1,926, p<0.001), LVEF was significantly lower in octogenarians (54.6% and 52.6%, p=0.005). The presentation of AMI was different between the two group. The incidence of ST-segment elevation MI (STEMI) was 70.7% in non-octogenarians and 62.0% in octogenarians. Non-STEMI with CK elevation and without CK elevation were 16.2% and 13.1% in non- octogenarians, and 20.9% and 17.1% in octogenarians. In-hospital mortality was higher in octogenarians (4.7% and 13.2%, P<0.001). Especially, octogenarians with STEMI and non-STEMI with CK elevation showed the highest in-hospital mortality. And octogenarians without CK elevation showed similar in hospital mortality with non-octogenarians with STEMI (Figure). Conclusions J-MINUET showed the poor prognosis of octogenarians who were diagnosed as AMI based on cTn. Acknowledgement/Funding None
