Depends on the steroid.
List of complete drugs you have taken please:
Include, ephedrine, clenbuterol, T3, testosterone, deca, tren...
ANY Prohormones or over the counter stuff when it was legal, and now (some stuff is still legal).
DMT derivatives (Pheraplex, p-plex that stuff) for example is associated with some issues.
Basically yes, there are plenty of steroids that enlarge the heart and can cause issues.
Basic outlines of what you have taken in the past and the dosages/durations will allow us to give you a pretty straight answer as to why you might have some issues.
But also remember that most issues are simply compounded by improper steroid usage, MANY MANY people have undiagnosed heart conditions that they live their whole lives with fairly sedentary and are never aware of.
Hence in current years kids dropping dead suddenly in sports is becoming more common, because the minor heart defects only cause issues under high stress loads...since our society rarely experiences these, the heart defects are not "natural selecting" themselves out of the gene pool.
I would highly recommend anyone interested in heavy steroid usage and powerlifting/weightlifting or highly competitive high stress activities...to go to a doctor and get their heart checked out with an EKG and a scan first to check for serious heart defects.
In highschool we had 2 kids drop dead of heart defects and die instantly, 4 guys I know personally needed surgery in highschool to correct holes and valve issues that only became apparent after they started competing in sports at a high level.
I myself have an improper heart arrhythmia called a shadow beat or a ghost double or something, heart will sometimes skip its one of its contractions then fire twice in rapid succession, so instead of lub dub lub dub it goes lub dub....lub lub, feels freaky.
It causes pretty severe pain when it hits and feels really weird. I had to wear an electronic heart monitor strapped to my chest for a week or two, and I had lots of EKGs and MRIs
In the end they basically told me, it hurts and its odd, but its not serious enough to risk fixing and we are not entirely sure we could fix it as its seems fairly random.
Scary stuff, but definitely something to think about if you intend to play with things that HIGHlY stress the body and allow you to place incredible loads on your muscles and organs during workouts and recovery.
