I agree, exercise if good, and I add too much exercise if bad.
Start slow and work your way up. Don't quit exercising.
You say you are overweight, that could be a big part of the problems: getting into a stronger physical condition, and high blood pressure.
Focus on exercise that use the large muscle: legs, but again start slow and build up. The exercise will strengthen you cardiovascular and burn calories. So, even if you don't cut down on your calorie intake, you can lose weight via exercise...careful not to increase you intake.
If you do this consistently and you don't find any improvement in a couple of months (keep records on how far, how fast, how often... and HRs) this is how you know if your are getting stronger, numbers don't lie.
Hi Jake
Have you tried to swin instead of jogging? My cardiolgist suggests me swimming is good to me.
I understand what you mean" I am worried to exercise now". months ago, I have same situation, after jogging and my heart seems going to jump out from my throat, then I refuse to go jogging anymore and was really scared/worried to any exercise. However, few months later, I found my immune system gets pretty bad, catching flu very easily and last-long and very ill even just a simple flu, so I decide to recover my regular exercise again, but just go slow jogging in shorter distance or swiming from time to time.
Never give up the exercise, this is what my doctor suggests me.
Wish you best
