Table 3 Myocardial perfusion data

From: Impaired myocardial perfusion is associated with increasing end-systolic- and end-diastolic volumes in patients with non-ischemic systolic heart failure: a cross-sectional study using Rubidium-82 PET/CT

All patients (N = 151)
Median global rest MBF (IQR) – ml/g/min 0.94 (0.76–1.09)
Median global stress MBF (IQR) – ml/g/min 2.18 (1.69–2.76)
Mean MFR (95% CI) 2.38 (2.24–2.52)
Mean coronary vascular resistance rest – mmHg/(ml/g/min) (95% CI) 89 (85–93)
Mean coronary vascular resistance stress – mmHg/(ml/g/min) (95% CI) 43 (39–47)
Median TID (IQR) 1.07 (1.02–1.14)
Median SRS (IQR) 2.0 (0.0–4.0)
Median SSS (IQR) 4.0 (2.0–7.0)
Median SDS (IQR) 2.0 (1.0–5.0)
