If he has a cardiologist who uses AS he should consult with him. Otherwise he's going to get a resounding NO from a US cardiologist whether it's dangerous or not. This is where demonizing steroids in the medical community does the most damage. The cardiologist is likely very unfamiliar with AAS but will give you the typical, programmed, knee jerk, response. So the question will, in fact, go unanswered.
If he's done steroids in the past he already has more information about what will happen than he's ever going to get from a cardiologist. And don't read this as a recommendation that he cycles. Like I said, there is no answer and there isn't likely to be.
