| Popis: | Objectives This study sought to determine whether combined assessment of autonomic tone plus cardiac electrical substrate identifies most patients at risk of serious events after myocardial infarction (MI) and to compare assessment at 2 to 4 weeks versus 10 to 14 weeks after MI. Background Methods to identify most patients at risk of serious events after MI are required. Methods Patients (n = 322) with an ejection fraction (EF) Results Mean EF significantly increased over the initial 8 weeks after MI. Testing 2 to 4 weeks after MI did not reliably identify patients at risk, whereas testing at 10 to 14 weeks did. The 20% of patients with impaired HRT, abnormal exercise TWA, and an EF Conclusions Impaired HRT, abnormal TWA, and an EF http://www.clinicaltrials.gov/ct/show/NCT00399503?order=1 ; NCT00399503 ) |
