In this article, we’ll delve into the specifics of heart disease, why it’s such a silent killer, and how to prevent it.

The risk factors for heart disease

There are several risk factors that can significantly increase your chances of developing heart disease, including:

If you have one or more of these risk factors, it’s essential to take steps to lower your risk of developing heart disease.

In conclusion, heart disease is a silent killer that affects millions of people worldwide.
