  1. The mean ± standard deviation are reported for age.
  2. Subjects were scanned at 1.5T magnetic resonance scanners (n = 661).
  3. 25 patients with pulmonary arterial hypertension and 17 healthy young adult volunteers were scanned at 3T magnetic resonance scanners.
  4. * CHILL-MI study comprised 85 patients, MITOCARE study comprised 80 patients. Note that some subjects were excluded compared to the original trials as long-axis images were missing. Duplicates with data from Skåne University Hospital were removed as this was one of the centers
