LOS ANGELES, Feb. 17 (UPI) -- U.S. recording artist David Crosby said in a statement Monday he is recovering from a cardiac catheterization and angiogram he underwent last week.
Crosby, 72, had the procedures Friday after a routine cardiac stress test indicated they were necessary to avoid a heart attack.
The left anterior coronary artery was found to be 90 percent blocked, and two stents were placed to provide blood flow to his heart muscle.
Crosby, who had a liver transplant in 1994, and has diabetes and a history of drug and alcohol issues, said he is expected to make a full recovery.
His sold-out shows scheduled for the Great American Music Hall in San Francisco Feb. 20-21 have been postponed to April 20-21 to allow him time to rest.
The five sold-out shows at the Troubadour in Los Angeles, previously scheduled for Feb. 23, 24, 25, 27, 28, will also be postponed to April. The exact dates will be announced shortly.
"I am very glad that I listened to my doctors and my family. It seems I am once again a very lucky man," Crosby said in a statement. "I'm sorry to have to move the dates, but I promise the music will be good when we do play them."
All Crosby, Stills & Nash shows will continue as scheduled. The first show of CSN's 2014 tour is to kick off in Richmond March 4.
