Angioplasty ke baad running safe? Walking kafi hai ya cardio jaruri? Please help!

Yaar, kal subah walk pe gaya tha. 3 km bhi nahi hua tha ki saans phool gayi, chakkar aane lage. Bahut darr lag raha hai honestly. Angioplasty ke baad se har choti cheez mein heart attack ka khayal aata hai.

Doctor ne kaha walking is best, lekin mera beta bolta hai "Papa, running karo, cardio improve hoga." Main confuse hoon. Walking se toh confidence aa raha hai slowly, lekin running ka dar hai ki kahin strain na aa jaye. Office mein bhi pressure hai - project deadlines, client meetings - sab manage karna hai. Wife bolti hai "bas ghar mein rest karo", lekin woh possible nahi hai.

Maine socha walking hi continue karun, lekin kya running se heart ko zyada fayda hai? Ya phir walking enough hai? Koi experienced bhai jo angioplasty ke baad exercise routine follow kar raha hai, pls guide karo. Kya running safe hai ya nahi? Aur koi specific breathing tips ho toh batado. Bahut anxious hoon yaar.
