What is coronary heart disease

CHD is a condition in which vascular supply to the heart is impeded by a trauma, thrombosis or spasm of coronary arteries.
This impairs the supply of oxygenated blood to cardiac tissue causing myocardial ischaemia which if severe or prolonged may cause the death of cardiac muscles (myocardial infarction).

Myocardial ischemia can also arise if oxygen demand is ↑ such as in severe ventricular hypertrophy (due to hypertension) or iron deficiency anemia (because of decreased capacity of blood to carry oxygen).
