angina and myocardial infarction

The heart is often a complex structure. This important organ delivers the body a life source, the oxygenated blood. These functions are carried out with the aid of the arteries and blood vessels. Blocked arteries of the heart or atherosclerosis are life-threatening conditions in particular when left undiagnosed and untreated. Blocked arteries could result into coronary artery disease wherein additional arteries circling the heart are involved. These arteries are also those responsible in bringing in oxygen to the heart.
