A member asked:

If my lcx and lad are less than 50% blocked (lcx due to stenting) but my ramus gets totally blocked, can this cause a heart attack?

Yes: Any coronary artery, including small branches, can cause damage to heart muscle cells if occludes (measured by cardiac enzymes). A heart attack from a smaller vessel is much less likely to cause death or significant disability.

Acute coronary syndr: Heart attack is a sudden blockage of an artery in heart such that there's no time to develop alternate ways to get blood to specific area of heart which then dies (causing chest pain/pressure etc in process). But if blockage develops slowly over time, heart may have time to develop corollary (alternate) flow, like driving on surface streets when freeway is blocked up. Work w/doc to optimize risk.
