Key result
Tall T waves without ST elevation in anterior MI linked to ~2-fold higher initial mortality.
Why the study?
The clinical significance of tall T wave without ST elevation on chest lead ECGs in acute anterior myocardial infarction within 6 hours was unclear.
Observational (n=85)
No
Answers are grounded in this paper and cite their sources.
May signal high early mortality risk in anterior MI without ST elevation; leaves open whether this ECG pattern warrants distinct acute strategies.

Noike et al. (1991) conducted an observational in Acute anterior myocardial infarction (n=85). Tall T wave without ST elevation (Type A) vs. ST elevation (Type B) and dome-shaped/plateau ST elevation (Type C) was evaluated on Mortality rate. Patients with acute anterior myocardial infarction presenting with tall T waves without ST elevation had a higher initial mortality rate (41.7%) but a significantly shorter time to peak CPK (12.6 hours) compared to those with ST elevation.
