Heart Health Guidelines May Not Apply Universally, Expert Says

Experts question if global heart health advice works everywhere, especially for people with low incomes.

Heart disease is a big killer, mainly in poor and middle-income countries.

Things like exercise and healthy food help prevent it, but not everyone can easily get them.

The study found that exercise is easier in rich places.

People in poorer areas do physical work, but often don't get exercise.

Healthy eating is also a challenge, as it can be costly to consume nutritious foods.

Standard guidelines might not fit everyone since environment and money matter.
