Table 4 LA strain data compared with normal values in healthy individuals

From: Left atrial strain - an early marker of left ventricular diastolic dysfunction in patients with hypertension and paroxysmal atrial fibrillation

Variable Study population (95% CI) Normal values according to metanalysis (95% CI) [8]
Mean contractile strain −14.14 (−15.61–-12.67) % 17.4 (16.0–19.0) %
Mean conduit strain 15.98 (14.76–17.20) % 23.0 (20.7–25.2) %
Mean reservoir strain 31.03 (29.11–32.96) % 39.4% (38.0–40.8) %
  1. Contractile, conduit and reservoir strains in patients with mild hypertension and paroxysmal AF are lower compared to normal population
