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.

A - masks don't protect you, they protect others, B - what % of the population leaves the house when they feel sick enough that they should wear a mask?
