exercise

    I am age 64, male with appropriate weight and reasonable blood pressure and statin reduced cholesterol of 113.    Recent CT suggests 40 to 70% blockages in two arteries, although I am able to enjoy a fairly physical outdoor lifestyle.  Last summer I was able to hike 10 miles round trip to 10500 feet in Wyoming and did not get short of breath.  However, I am concerned about more vigorous aerobic excercise.   What precautions should I take, and would stenting these arteries be of any benefit in terms of activity.  I am aware it would not help longevity.  
   Also before my successful ablation, I think I had an a fib attack triggered by an adverse reaction to a flu shot.  I have been reluctant to have a flu vaccination now.  Should I continue to avoid it?

My apologies forum readers.  I thought I was posting on the Doctor forum.  However, if anyone does have experience or imput, it would be welcome.

Hi.. I would say swimming !!
Flu vaccination ,I never went to ask one . Never will. I stay healthier without mercury.

I'm about your age, BP and Cholesterol controlled by medications, have numerous stents and currently have two arteries about 60% blocked.  My Cardiologist strongly urges me to continue daily aerobic exercise, which I try and do - either 4 mph walking (tough to do in the winter), aerobic machines or swimming.  I have found consistent, daily exercise to be a great way for me to monitor my cardiac health.  On several occasions I have been able to detect blockages that were successfully stented as I suddenly became short of breath and very weary, as I noticed a difference in my exercise tolerance.
