Tottenham manager Harry Redknapp believes he will be back on the White Hart Lane touchline in a matter of weeks.
Redknapp revealed he felt chest pains and struggled to breathe as he ran at his home late last week. The 64-year-old subsequently had two stents inserted to unblock coronary arteries on Wednesday, forcing him to miss Spurs' Europa League game at Rubin Kazan.
"I have a running machine at home and run or jog for around half an hour several times a week to help stay fit," he told The Sun. "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. I just stopped running there and then and I went to see the club doctor at Spurs. He got me in to see a specialist on Saturday and by Monday I was in hospital.
"I've had narrow or blocked arteries for some time. I've been taking tablets for it just like a lot of people my age do. It's no big thing."
Redknapp hailed Wednesday's procedure a success, saying: "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. I'm lucky that I work in an industry where there are experts and specialists on hand to look after you properly."
The Spurs boss has been instructed by his doctors to rest for the next few weeks, but the resilient manager is already looking forward to returning to White Hart Lane.
"After this weekend we have a break for international matches coming up anyway. After that I'll be back in at Tottenham and back on the training pitch."
"This isn't going to stop me doing the job I love. I love my football and won't be walking away any time soon. I can assure everyone I'm doing okay. It won't stop me running - I might even do the marathon one day."
