Dubai, United Arab Emirates (CNN) — Heart disease is the leading killer worldwide, and the largest cause of death in the United States.
These diseases killed an estimated 17.9 million people in 2019, representing 32% of all deaths worldwide, according to the World Health Organization (WHO).
But not all heart diseases are the same, and they can affect the blood vessels going to the heart, or the brain, heart muscles, valves, and other areas of the body.

A cardiac arrest is different from a heart attack, but almost any known heart condition, including a heart attack, can cause a heart attack.
