Regional wall motion abnormalities were present with a grade 1a/4 left ventricular diastolic dysfunction with increased right ventricular wall thickness
The size of the heart, left and right ventricular wall thickness
were separately calculated by randomly selecting 6 different places in the sections, using ocular and stage linear micrometer (Oakley, 2004).
As a novel, we showed that severe and moderate OSA patients had left (3) and right (4) ventricular global (systolic and diastolic) dysfunction with an increased myocardial performance index (MPI), and continuous positive airway pressure (CPAP) therapy significantly decreases left and right ventricular wall thickness
and improves ventricular global function (MPI) even with six months of CPAP usage (3,4).
