Garry Shandling had been planning to make a trip to the emergency room shortly before his death on Thursday.

TMZ reports that the comedian had been experiencing shortness of breath and aches on Wednesday afternoon so he called over a doctor friend who gave him a check up and told him that if he was still in pain on Thursday he should get to a hospital.

Shandling did not make it in time, however, calling 911 Thursday morning and falling unconscious before he could even finish his call with the dispatcher, dying just hours later of a massive heart attack.
