The three important public tools for addressing a heart disease includes hospitals, internet and fact sheet on cardiovascular diseases.
<u>EXPLANATION:</u>
The Internet provides wholesome details regarding heart disease and it is one of the public tools that could be accessed instantly whenever we need to address heart disease.
Hospitals are another source of public tool where the doctors who excel in addressing a heart disease provide relative information.
Fact sheet on cardiovascular disease is a public tool released by WHO that provides details about heart disease.
It may be either Disagreements or Intractable Situations. I'm not completely sure, sorry. I'd wait for another to come answer your question just to be safe.
