Taking ISMN for a long time might harm your blood vessels by making them more stressed and less able to function properly, not because of how your body usually breaks down the drug, but because it triggers two specific harmful processes in the vessel walls.

Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
Evidence from Studies
Supporting (1)
This study shows that long-term use of ISMN, a heart medication, can harm blood vessels by increasing harmful stress and tightening signals — and this happens without needing a specific enzyme (ALDH-2) that other similar drugs use, which matches the claim.
