I had a stent emplace on my Anterior Decending artery. I went through rehab and the whole 9 yards. I went back to work 2 1/2 weeks after the attack. I'm a mechanic by trade. 3 weeks after starting work I hammered a wheelbearing out of a GMC pickup. Pushed it too hard and ended up back in for 2 days. Upper body workouts will get to you the quickest. Cycling would be good for you.
BUT DO NOT OVERDO IT!!!!!!!!!!!!!
Listen to yourself. When you get tired and winded call it a day. Work back slowly and all will be well. Be careful out there. And welcome back.
