The drummer was forced to pull out of two concerts after falling ill and having to undergo a "minor medical procedure" and now he tells Tv and radio presenter Eddie Trunk the reports about his health were vastly overblown.
He says, "The likes of Tmz and some others out there said that I had previous problems, that I had existing heart problems from the past and it was something that I always had, which was just completely not true.
"I’ve never had any problems in the past. It’s just strictly a hereditary thing. There’s a family history, and I was the victim. But no more.”
He insists he wasn't as near to death as some outlets reported: "It wasn’t my time... for my ticket to be punched. And so I got fixed, and I’m back 150 per cent, and everything is as good as it can possibly be.
"I kept getting this burning sensation in my chest, so I kept taking antacids and, finally, my Gp (doctor) said to me, 'Just to make sure and rule out that it’s anything cardiac related, go and take a stress test'.
"So I went and took the stress test. I got through the echocardiogram with flying colours. He said that my cardiovascular system looked like that of a 48 or a 50-year-old, and I’m 64! And then I got on the treadmill, and when I got on the treadmill, it started to bother me a little bit."
Kramer reveals he underwent an angioplasty, and had two stents added.
He adds, "Now it’s better than ever. I feel great and the playing is great."
Kramer's son Jesse took his place in Aerosmith while dad was recovering.
