The 83-year-old suffers from COPD – chronic obstructive pulmonary disease – and he was rushed to the center after a 911 call on February 19.
Sources said that paramedics on the scene didn’t want to take any risks with the star, opting instead to get him in front of a doctor as soon as possible.
The actor has has previously spoken about his struggle with COPD, which makes it increasingly difficult to breathe.
Leonard – famous for his portrayal of Commander Spock – has been in and out of hospitals multiple times throughout the last few months, following his announcement that he suffers from the potentially fatal lung disease.
Leonard took to Twitter in 2014 to share his diagnosis, and some advice, saying: ‘I quit smoking 30 years ago. Not soon enough. I have COPD. Grandpa says, quit now!! LLAP [Live Long and Prosper]’.
The former science fiction star blames his illness on the years he did spend smoking, as it is said to be caused by the habit.
