Hey press1, I dug up  some information I have been reading the last couple of years.

 

What kind of symptoms do you have only palpitations or more? HB and HT need to be in check, it may be elevated on cycle/ blast. This can give you some sensations and irregular heart rhythm when you get warm and start sweating, even when take a hot shower it can feel troubling. I would definitely let this checked out by a doctor when you are worried about this.

 

The only possible problem is that you must have an episode when they examine you.  This took almost 1  year for me, they give you a monitoring device and 24/48 hrs. the monitor. But it never happens when you got the device on you, lol.

 

I have rhythm problems my condition is called AVNRT and I got third degree AV blocks in my sleep.

The AVNRT is a condition that has episodes so when I get it , often the following days my body is somehow triggered and alarmed so I get the high heart rate more often in the following days. See the link below for some explanation about this condition. Stress can be a trigger, like when I sleep less because of worrying about something and workout and don’t listen to my body signals.

The 3rd degree av block is something else, this happens sometimes when I sleep. My doctor has implanted a loop recorder in my chest. So they can monitor my heartrate, 1 time every day the device sends the info to the hospital. This is how they found this 3rd av block problem. Because of this problem I can’t get any medication because of the contra indication. Medicine to lower my heart rate can get me in the AV- blocks and the other way around. There are studies that indicates that HGH can be beneficial for 3rd degree av blocks and heart failure, that’s why I am on a low dose hgh protocol. Also peptides like GHRP with CJC can be a good tool.  If someone is interested I can post links of these studies.

The thickened heart tissue is created with long intense training and like you said gear is not helping. The steroids will keep de thickening consistent even when you don’t workout anymore.  I had wall thickness of 19mm, when I researched on the web I was really alarmed with his report : One of the elite bodybuilders has the largest left ventricular wall thickness (16 mm) ever reported in a power athlete. Retrospectively, 43% of the drug-free bodybuilders and 100% of the steroid users had left ventricular wall thickness beyond the normal range of 11 mm. In addition, 1 drug-free subject and 3 steroid users were beyond the critical mark of 13 mm. No subjects demonstrated diastolic dysfunction. In contrast to previous reports, we have demonstrated that left ventricular wall thicknesses >/=13 mm can be found routinely in elite resistance-trained athletes. The use of anabolic steroids concomitant with intensive resistance exercise does appear to augment left ventricular size without dysfunction. Anabolic steroids may accelerate left ventricular wall thickening indirectly by increasing strength, thus augmenting the pressor response.  Also the ejection fraction can be chanced this is the pomp function.

To restore your hearts inner wall to a normal size you can’t only stop training or your roids. You need to stop training or at least stop your intense workouts and stop all AAS and stims that have a effect on your heart or cardiovascular system. This a link with multiply studies and a more readable version. Here is a small piece of the article that will hopefully give you a better view on the  possibility on reversing the thick heart wall. At the bottom you find the source so you can still see the real report, i don’t do brosience!  

Athlete’s heart is not entirely permanent.

In many cases, athlete’s heart reverses completely or largely with de-training.(113-118) Heart disease generally doesn’t regress, at least without surgery, drugs, or other treatments.(119-122)

Many of the changes in “athlete’s heart” start to reverse themselves after just 8-12 weeks.(123-127) Hearts of athletes even shrink during the rest season when they reduce their training levels.(128-130) This would probably not happen if “athlete’s heart” was a form of heart disease.(131,132)

In highly trained athletes with more advanced “athlete’s heart,” however, the changes sometimes don’t completely go away years after they stop training.(133-137) They mostly regress, but not completely.

This is especially true for endurance athletes, who usually have much larger hearts.

But most measures still fall back to the upper end of the normal range.(138-142)

One study found that retired pro cyclists still had significantly enlarged hearts 30 years after retirement. However, the absolute differences in heart size were minor. There was also no evidence this caused any long-term problems.(143)

Another study on elite athletes found that after six years of no intense training, most changes in heart size and function were back to the normal. About 20% of the athletes still had higher than normal heart volumes, but there was “no clinical or echocardiographic evidence of systolic or diastolic LV [left ventricle] dysfunction, cardiac symptoms, or impaired physical performance.”(144)

These athletes also tended to remain more active later in life and/or gain more weight, which explained about 50% of their persistently enlarged hearts.

That said, the authors could not “exclude the possibility that this marked residual chamber enlargement” (that was not explained by continued training and increased body weight), “could ultimately lead to clinical consequences [heart problems] later in life.”(145)

The largest study of this kind, using a cohort of 947 Olympic endurance athletes, found that after an extended break there were significant reductions in heart size and no evidence of heart dysfunction.(146) However, these athletes were much younger on average, so it could be that heart damage only occurs after a longer period of time.

Most other studies, however, have also shown that athlete’s with persistently enlarged hearts tend to have heart function that is about the same as the average population.(147,148)

Other studies indicate that heart function does sometimes change when the heart does not completely go back to normal, but there’s little evidence these changes are bad.(149,150)

We already discussed the studies that seem to disagree with this conclusion in the previous part of this article.(151-153)

In all of these studies, most of the athlete’s hearts substantially shrunk after they stopped exercising. It didn’t always completely return to normal, but it did regress as you would expect any adaptation to do if you stop training

I hope this will help you and maybe other people on the board.  You need to know a lot of studies are not with bodybuilders. This doesn’t mean we are out of risk zone, the opposite is true. Better take some time of between cycles or blasts. Also intense workout periods need to be switched with periods of rest and recovery. Also for people who are new to this. Do your homework like bloods. Buy blood pressure monitor and Sp02, these devices are cheap!  And should be in everyone's safety kit.

Thanks bro! My goal is the 70-80s look, the golden era.
