This study aimed to investigate whether OSA patients without heart morbidity develop LV dysfunction, and to assess the effect of continuous positive airway pressure (CPAP) on LV function.<\/jats:p><jats:p>Twenty-nine OSA patients and 12 control subjects were studied using technetium-99m ventriculography to estimate LV ejection fraction (LVEF), LV peak emptying rate (LVPER), time to peak emptying rate (TPER), peak filling rate (LVPFR) and time to peak filling rate (TPFR) before and after 6 months of treatment with CPAP.<\/jats:p><jats:p>A significantly lower LVEF was found in OSA patients, compared to control subjects, (53\u00b17<jats:italic>versus<\/jats:italic>61\u00b16%) along with a reduced LVPER (2.82\u00b10.58<jats:italic>versus<\/jats:italic>3.82\u00b10.77 end-diastolic volumes\u00b7s<jats:sup>\u22121<\/jats:sup>).
