An estimated
of 17 million people dies of cardiovascular diseases, particularly heart
attacks and strokes, every year.
Over 80% of CVD deaths take place in low- and
middle-income countries. By 2030, more than 23 million people will die annually
from CVDs
Experts say
substantial number of these deaths can be attributed to tobacco smoking, which
increases by three-fold the risk of dying from coronary heart disease and
cerebrovascular disease.
They list physical inactivity and unhealthy diet as
other main risk factors that increases individual risks to cardiovascular
diseases.
Heart attack
is viewed as a global epidemic, making the World Health Organization to
advocate the provision of actionable information for development and
implementation of appropriate policies.

This is most commonly due to occlusion (blockage) of a coronary artery following the rupture of a vulnerable atherosclerotic plaque, which is an unstable collection of lipids (cholesterol and fatty acids) and white blood cells (especially macrophages) in the wall of an artery.
The resulting ischemia (restriction in blood supply) and ensuing oxygen shortage, if left untreated for a sufficient period of time, can cause damage or death (infarction) of heart muscle tissue (myocardium).
Typical symptoms of acute myocardial infarction include sudden retrosternal chest pain (typically radiating to the left arm or left side of the neck), shortness of breath, nausea, vomiting, palpitations, sweating, and anxiety (often described as a sense of impending doom).
Women may experience fewer typical symptoms than men, most commonly shortness of breath, weakness, a feeling of indigestion, and fatigue. A sizeable proportion of myocardial infarctions (22–64%) are "silent", that is without chest pain or other symptoms.
