David Crosby of the rock group Crosby, Stills & Nash underwent heart surgery on Valentine's Day and has postponed several sold-out California shows.
The news was reported on the 72-year-old performer's web site on Monday, Feb. 17.
At the urging of his doctor, on Friday, February 14, David Crosby underwent a cardiac catheterization and angiogram, based on the results of a routine cardiac stress test," the message said. "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."
"David is expected to have a full recovery," the message added. "He did not have a heart attack, though it is certain that had he chosen to ignore his doctor's urgent recommendation, it would have led to one."
Crosby added: "I am very glad that I listened to my doctors and my family. It seems I am once again a very lucky man. I'm sorry to have to move the dates, but I promise the music will be good when we do play them."
Crosby has had several health problems over the years. In 1994, he underwent a liver transplant -- a procedure paid for by fellow rock star Phil Collins.
"Look, I have maybe 10 more years, if I'm lucky," he said in an interview with the website Jazz Wax in 2013. "I have three fatal diseases -- hepatitis C, diabetes and heart disease. All killers, and no cure. I'm managing them. I'm going to the gym three days a week, I'm feeling strong and I can still make audiences feel great."
Meanwhile, all Crosby Stills & Nash concerts are still set to take place, starting in Richmond, Virginia on March 4, although not all rescheduled dates have been announced. Check out a list below.
