I am a 65 year old male, 6'5" and 210 lbs. A year ago following successful a fib ablation, a CT suggested 40-70% blockages in two arteries. I can walk and golf 18 holes on a hilly golf course and hike 10 miles at high elevation in the Wyoming mountains. Yet, I tend to get short of breath when I carry heavy objects up stairs or when doing physical work that requires lifting or straining. I know stents do not extend life, but would a stenting the arteries give me more energy for my active lifestyle?
