I am a 41 year old male with 25 stents spread out through my RCA, DX, and LAD.  My LAD fully jacketed and no bypass can be done there.  I am also have hypogonadism and have been on Testim for four years.  While on the Testim, my maximum heart rate was 180-190bpm.  When I went off of it for three months, about 2 months in my exercise tolerance dropped and my maximum heart rate seemed to be pegged at 162bpm.  I passed a nuclear stress test, but felt I got a false negative.  I only made it 10 minutes when my usual time is around 15:30 minutes. 

I am not sure if this is due to the age of my heart rate monitor, but I used a watch and got within the ballpark.  I am now on a Testosterone renormalization protocol and my hypogandism was deemed reversible (finally found a good doctor who specializes in this).  I was on HCG 2000IU every other day for twenty days, 50 mg Clomiphene twice a day for two months and 10mg Tamoxifen twice a day for two months (I am a little over 1 month in). 

My testosterone is increasing and I have noticed my exercise tolerance has really improved.  It is probably the best it has ever been.  However, my maximum heart rate is still around 163 although it will briefly shoot up to 180-190 every now and then.  The frequency of these brief increases has increased a little since I started my therapy. 

Should I be concerned?  I also forgot to mention that prior to starting the Testosterone replacement protocol I was getting angina during my workouts.  This has since stopped.  I have read that Tamoxifen, for males at least, widens the blood vessels over time.

My resting heart rate is around 58-60 bpm.

Concerned,

Gerald
