Irregularity in the heart beat or action. arrythmia
Complete stopping of heart activity. Cardiac arrest
Pathological condition of the heart in which there is a reduced outflow of blood from the left side of the heart because the left ventricle myocardium has become too weak to efficiently pump blood. Results in weakness, breathlessness, and edema. Congestive heart failure

Weakness in the wall of an artery resulting in localized widening of the artery. Aneurysm
Thickening, hardening, and loss of elasticity of the walls of the arteries. Most often due to artherosclerosis. Arteriosclerosis
The most common form of arteriosclerosis. Caused by the formation of yellowish plaques of cholesterol on the inner walls of arteries. atherosclerosis
The obstruction of a blood vessel by a blood clot that has broken off from a thrombus somewhere else in the body and traveled to the point of obstruction. Embolus
Inflammation of a vein resulting in the formation of blood clots within the vein. Thrombophlebitis
A blood clot within a blood vessel. Thrombus
