Angioplasty ke baad running? Doctor kya kehte hain aur dil ka darr kaise hatayein?

Yaar, ek doubt hai. Post-angioplasty (almost 2 months ho gaye) main walking kar raha hoon, roz 30-40 mins. Lekin mujhe lagta hai ki zyada kuch ho nahi raha, thoda slow progress hai. Mera ek friend bolta hai “bhai running start kar, heart strong hoga”. But mujhe darr lagta hai, kahi strain na aa jaye.

Kal hi maine 5 mins very slow jogging try kiya, aur thoda breathless feel hua. Heart rate monitor pe 135 dikh raha tha. Ab doctor ne kaha hai “moderate intensity” rakho, but what is moderate for a heart patient? Kya walking hi sufficient hai ya running bhi zaroori hai?

Meri age 48, sedentary lifestyle tha pichle 10 saal. Ab lifestyle change karna chah raha hoon. Koi experienced bhai hai jiska bhi heart issue hua ho? Walking se kaam chal jayega? Ya running ka koi safe way hai? Plz share your experience, main confuse hoon.
