Normal lvef at stress
Web16 de mar. de 2024 · The definition of classical LFLG AS proposed in the guidelines 2, 3 includes LVEF <50% but does not include any criteria for low flow state. Hence, a few patients with mild‐to‐moderate LV systolic dysfunction (LVEF 40%–50%) and large LV end‐diastolic volume may generate a mean flow rate ≥250 mL/s at rest. Web18 de mar. de 2024 · In healthy controls, no significant difference was seen in stress MBF between the 3 protocols. In patients with known or suspected CAD, and those with heart failure and mild systolic impairment (LV ejection fraction (LVEF) ≥ 40%) no significant difference was seen in stress MBF between standard and high dose adenosine.
