Lamar Odom's condition has improved in a hugely important way...his heart is on the mend, according to TMZ.
Sources familiar with the situation says, tests on Lamar's heart Friday morning revealed his heart function is better. Doctors have told Lamar's friends and family that it is a good sign of improvement, that a critical organ is responding.
Doctors have asked for calm in Lamar's room because they do not want him stimulated, because non-stimulation promotes healing.
Toward that end, doctors have ordered that virtually no one have access to Lamar's room, but Khloe is still by Lamar's bedside.
