In an interview, he said he felt lucky and joked that he wants 'four more years' to live, referring to the presidential term of office.
The US President, George W Bush, called Mr Clinton to wish him a speedy recovery.
Mr Clinton's wife, Senator Hillary Clinton, cancelled her appointments to be with her husband.
