“…Establishing a Pd/Td cutoff value of 1000 mmHg/s to define systolic dysfunction with this means alone has been proposed to be reasonable 9 . The correlation between LVEF and Pd/Td was positive but weak, which is an aspect that has already been described in medical publications 9 , although when corrected LVEF is correlated with Pd/Td, Pearson's coefficient shows a slight improvement, from 0.457 to 0.547 (p = 0.6335, with no significant difference; Fig. 5).…”

“…Tabla 2. Reclasificación de pacientes a diferentes categorías de FEVI de acuerdo con la gravedad de la insuficiencia mitral Se ha planteado que es razonable determinar un valor de corte de dP/dT de 1,000 mmHg/s para definir disfunción sistólica con este medio solo 9 . La correlación entre FEVI y dP/dT fue positiva pero débil, un aspecto ya descrito en las publicaciones médicas 9 , aunque al correlacionar FEVI corregida con dP/dT el coeficiente de Pearson mejora discretamente, desde 0.457 hasta 0.547 (p = 0.6335, sin diferencia significativa; Fig.…”
