T-Wave Axis Deviation and Prognosis in Chagas' Cardiomyopathy

Description

Salles et al used the T-wave axis in the electrocardiogram to stratify patients with Chagas' cardiomyopathy based on prognosis. This can help to identify a patient who may benefit from more aggressive management. The authors are from Clementino Fraga Filho University Hospital and Federal University of Rio de Janeiro in Rio de Janeiro, Brazil.

Patient selection: Chagas' cardiomyopathy

Outcomes: sudden death, Chagas'-related mortality, all-cause mortality

Parameters:

(1) frontal plane T-wave axis on admission

(2) electrocardiogram at baseline

T-wave Axis	Interpretation
< -15 degrees	abnormal
-15 to 14 degrees	borderline abnormal
15 to 75 degrees	normal
76 to 105 degrees	borderline abnormal
> 105 degrees	abnormal

T-wave Axis	Baseline ECG	Prognosis
normal	NA	good (90% survival at 10 years)
borderline abnormal	normal	fair
borderline abnormal	abnormal	guarded
abnormal	NA	poor (40% survival at 10 years)
