Persistent, small increases in Tn and MB are thought to reflect on-going
ischemia/injury and should be investigated.
Patients with such increases are
greater risk of MI or sudden cardiac death within the next 6-9 months.
The diagnosis of MI may remain uncertain even after taking into account
patient history, ECG, & serum biomarkers…to improve certainty, echocardiography is done to detect ventricular systolic dysfunction & ischemic/infarcted regions.
