Long term favorable prognostic value of negative treadmill echocardiogram in the setting of abnormal treadmill electrocardiogram: a 95 month median duration follow-up study.

Background: The aim of this retrospective study was to assess if negative treadmill echocardiographic (NTME) results retained their favorable prognosis over a long period of follow-up (median, 95 months) in the setting of ischemic stress electrocardiographic (ISECG) results.

Methods: Consecutive patients with NTME results were analyzed as 2 groups (those with ISECG results and those with normal stress electrocardiographic results). Patients were followed up for a median duration of 95 months to identify major adverse cardiac events (MACEs), including all-cause death, myocardial infarction, and coronary revascularization.
