Krishna Sudhir: What happens during a heart attack?

What happens during a heart attack?

Approximately seven million people around the world die from heart attacks every year. And cardiovascular disease, which causes heart attacks and other problems like strokes, is the world's leading killer. So what causes a heart attack? Krishna Sudhir examines the leading causes and treatments of this deadly disease. [Directed by Chadwick Whitehead, narrated by Addison Anderson, music by Dreikelvin Media & Sound].

Heart attacks kill around seven million people worldwide each year, making them the leading cause of death. They occur when fatty plaques build up in the arteries and suddenly block blood flow to the heart. Symptoms can be dramatic, like crushing chest pain, or subtle, especially in women and people with diabetes. While emergency treatments save lives, small changes in diet, exercise, and risk management can prevent countless tragedies.
