Despite favorable correlations, some investigators have proposed that the method is an unreliable means of assessing filling pressure. In decompensated advanced systolic heart failure, E/e’ showed a poor correlation with intracardiac filling pressures, especially in large LV volumes, worse cardiac indices, and in the presence of cardiac resynchronization therapy. These results are likely driven by significant mitral regurgitation (present in 22% of the patients) as well as half of the patients with a broad QRS and consequent abnormal septal motion.The study should remind us of the pitfalls of measuring E/e’.

Mas todos sabem das limitações do marcador, tantas vezes criticado.
