Atherosclerosis A number of ageing changes occur in the aorta‚ arteries and arterioles. The age related changes that occur in muscular arteries are usually known as arteriosclerosis. It involves alterations of the smooth muscle hypertrophy and intimal fibrosis further reducing the diameter of the vessel. Atherosclerosis is the most common arterial abnormality known as arteriosclerosis which is defined as the stiffening or hardening of the artery walls. However‚ atherosclerosis refers to the hardening

EKG changes) will disappear. Myocardial injury occurs when myocardial oxygen supply is unable to meet cellular demand. An example of this would be the sudden loss of blood supply due to the complete occlusion of a coronary artery as a result of a thrombus formation at the site of a plaque. Without oxygen‚ the myocardial cells are unable to function. Oxygen supply may be restored through measures such as the administration of clot-dissolving drugs (thrombolytics) or by procedures such as angioplasty

MITRAL VALVE DISEASE MITRAL STENOSIS Mitral stenosis is almost always rheumatic in origin‚ although in the elderly it can be caused by heavy calcification of the mitral valve apparatus. There is also a rare form of congenital mitral stenosis. In rheumatic mitral stenosis‚ the mitral valve orifice is slowly diminished by progressive fibrosis‚ calcification of the valve leaflets‚ and fusion of the cusps and subvalvular apparatus. The flow of blood from left atrium to left ventricle
