Football manager Harry Redknapp has admitted his recent heart scare was "a warning sign from within", but vowed to be back doing the job he loves within weeks.
The 64-year-old Tottenham Hotspur boss underwent a procedure to unblock his coronary arteries on Wednesday after complaining of chest pains and breathing problems while running at home.
Speaking after the successful treatment, the former West Ham player said he was feeling "fine" and joked that he may even run a marathon in the future.
He told The Sun: "I have a running machine at home and run or jog for around half an hour several times a week to help stay fit. But this time I went on and had been running for no more than about two minutes when I felt pains in my chest. I had hardly got going when it went tight and I was struggling to breathe.
"As soon as that happens you know the best thing to do is stop immediately, which I did. I wasn't that frightened if I'm honest - but it was clearly a warning sign from within."
After the incident the grandfather said he went to see the Spurs club doctor and was referred to a specialist who recommended the artery-widening procedure - believed to be a coronary angioplasty.
During the treatment, which forced Redknapp to miss Spurs' trip to Russian club Rubin Kazan this week, two stents were inserted into arteries to improve his blood flow from the heart.
"I've had narrow or blocked arteries for some time," added the manager, who is recovering at his Dorset home after being discharged from hospital. "I've been taking tablets for it just like a lot of people my age do. It's no big thing. They didn't even put me out. I was sort of half-conscious while they did what they had to do and now it's all taken care of.
"I haven't had a heart attack. It was just that the specialist told me the arteries needed doing now. So we arranged it all and here I am. I feel fine and everyone tells me I will soon be feeling better than ever."
Redknapp says his doctor has advised him to put his feet up "for the next couple of weeks" but revealed he is looking forward to returning to Premier League management. "This isn't going to stop me doing the job I love," he added. "I love my football and won't be walking away any time soon. It won't stop me running - I might even do the marathon one day."
