Key result
A widening of the frontal QRS-T angle above 0° during follow-up was independently associated with an increase in mortality in patients with heart failure (P<0.0001).

Serial QRS-T angle changes were associated with HF survival; hypothesis-generating and requires prospective validation before clinical adoption.

Does widening of the frontal QRS-T angle predict increased mortality in patients with heart failure?
p-value: p=<0.0001
Widening of the frontal QRS-T angle over time is an independent predictor of increased mortality in patients with heart failure.
Gotsman et al. (2018) conducted a cohort in Heart failure (n=2,929). Widening of the frontal QRS-T angle vs. Stable or narrowing QRS-T angle was evaluated on Mortality (p=<0.0001). A widening of the frontal QRS-T angle above 0° during follow-up was independently associated with an increase in mortality in patients with heart failure (P<0.0001).
