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. Web25 de abr. de 2024 · Patients with a normal LVEF (≥50%) without chamber dilation were included irrespective of the test indication. Exclusion criteria were age < 20 years, LVEF <50%, LV volume index (LVVI) ≥75 mL/m 2, baseline or stress-induced wall-motion abnormalities, and more than moderate valvular disease.

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. Web(BMI≥30), overweight (25≤BMI<30), and normal weight (BMI<25). The LVEF was 76.7±7.6, 76.2±9.2 and 78.5±9.9 in obese, overweight and normal weight subjects respectively … WebA reduction in LVEF after stress seems to be related to an increase in ESV. The inadequate contraction may cause the increase in ESV ( 2 , 16 ). It has been demonstrated that patients with myocardial stunning have more severe clinical, angiographic, perfusion, and function findings ( 2 , 16 ), suggesting that the identification of this phenomenon may have a … diabacore ingredients
