Heart disease is the single greatest cause of death in most countries. According to the WHO, CVDs account for around 17.9 million deaths every year, which is 32% of all deaths worldwide. Of these deaths, 85% are due to heart attacks and strokes. In fact, even though there is much advancement in medical care, people do not know what to look out for when experiencing a heart attack, and most deaths occur before a person can be medically treated.
