If people are this concerned about heart health, they'd be wise to continue a zero-covid lifestyle into 2026 and beyond, since each re-infection (which vaccines don't prevent) increases the risk of severe health outcomes, including heart-related issues among lots of others.

Yet I only see about .5-1% of the population in my area these days wearing any kind of mask/N95 respirator in public.
