Table 4 Multiple regression: predicting new onset AF in all HCM patients

From: Incremental value of left atrial booster and reservoir strain in predicting atrial fibrillation in patients with hypertrophic cardiomyopathy: a cardiovascular magnetic resonance study

  HR (95% CI) P value
Age ≥ 55 years 5.22 (2.12–12.83)  < 0.001**
LA reservoir strain ≤ 18% 1.21 (0.44–3.32) 0.717
LA booster strain ≤ 8% 3.08 (1.43–6.64) 0.004**
LAEF ≤ 45% 1.73 (0.68–4.40) 0.252
  1. LAEF left atrial ejection fraction, HR hazard ratio, LA left atria, LAEDV left atrial end diastolic volume
  2. *Indicates a significant difference of P < 0.05
  3. **Indicates a significant difference of P < 0.01
