And marathon running every day
See http://qr.ae/Khwh7 .
However, if you rarely stress your heart these drugs are basically causing the chemical equivalent (depending on dose and route of entry) of running a 10K without being able to stop. Interestingly cocaine/amphetamines can have a protective effect on the heart (in terms of heart attacks) because they cause your body to recruit more blood vessels to deal with the times when the drug causes serious vaso-constriction and limits blood flow (much bigger issue with cocaine), so if an entire artery was blocked you would have "collaleral" flow which would save that tissue. The problem is that chronically these events could cause micro-infarcts (think very small heart attacks) resulting in loss of functional heart tissue that could lead to heart failure. Unfortunately I think our generation are the guinea pigs to see how much "chronic" use (every day) of these meds actually matters
I'm curious...
Could marathon running/increased heart rate be innocuous for those with BPs of 100/60, but more risky for those with higher BPs? Also, what if one's BP doesn't increase at all on meds? (even if one's heart rate increases).
