Global longitudinal peak strain was an independent predictor of heart failure hospitalization or cardiovascular death (P<0.0001), including in patients with preserved ejection fraction (P=0.04).

Does speckle strain echocardiography predict the composite of heart failure hospitalization or cardiovascular death in patients with heart failure?
Speckle strain echocardiography, specifically global longitudinal peak strain, is an independent predictor of adverse outcomes in heart failure patients regardless of ejection fraction.
p-value: p=<0.0001
BACKGROUND: While speckle imaging has been shown to predict outcome in patients with heart failure (HF), it remains unclear whether speckle strain predicts outcome in patients with HF with preserved ejection fraction (HFPEF). METHODS: Four hundred twenty patients with HF by Framingham criteria and either: left ventricular (LV) EF -15 (χ(2) = 4.1, P = 0.04), whereas LVEF did not predict event-free survival. CONCLUSION: Speckle strain echocardiography is an important predictor of outcome in HF patients with both depressed and preserved LVEF.
Stampehl et al. (Sat,) conducted a observational in Heart failure with depressed and preserved ejection fraction (n=420). Speckle strain echocardiography (Global longitudinal peak strain) was evaluated on Heart failure hospitalization or cardiovascular death (p=<0.0001). Global longitudinal peak strain was an independent predictor of heart failure hospitalization or cardiovascular death (P<0.0001), including in patients with preserved ejection fraction (P=0.04).
