the resistance that the ventricle of the heart has to overcome to eject the blood from the ventricle chamber during systole.
hemorrhage that happens immediately prior to death as a result of tissue anoxia.
a sac formed by the dilation of the wall of an artery, vein, or the heart; it is filled with fluid or clotted blood, often forming a pulsing tumor.
any of a group of diseases characterized by the thickening and loss of elasticity of arterial walls.
inflammation of an artery
a common form of arteriosclerosis with formation of deposits of yellowish plaques (atheromas) containing cholesterol, lipoid material, and lipophages in the intima and inner media of large and medium-sized arteries.
slowness of heartbeat, as evidenced by slowing of the pulse rate.
acute compression of the heart caused by increased intrapericardial pressure due to the collection of blood or fluid in the pericardium from rupture of the heart, penetrating trauma or progressive effusion.
thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles.
excessive or abnormal accumulation of fluid, as of blood in a part.
acute overload of the right ventricle due to pulmonary hypertension, usually resulting from acute pulmonary embolism.
cor pulmonale, acute
heart disease characterized by hypertrophy and sometimes dilation of the right ventricle secondary to disease affecting the structure or function of the lungs, but excluding those pulmonary disorders resulting from congenital heart disease or from diseases primarily affecting the left side of the heart.
cor pulmonale, chronic
a condition in which blood clots form throughout the body's small vessels.
Disseminated intravascular coagulation (DIC)
congenital displacement of the heart outside the thoracic cavity because of maldevelopment of the pericardium and sternum.
inflammation of the tunica intima of an artery; intimits.
diffuse patchy thickening of the mural endocardium, particularly in the left ventricle due to proliferation of collagenous and elastic tissue usually in association with congenital cardiac malformations.
layer of epithelial cells that lines the interior of structures such as cavities of the heart, lumina of blood and lymph vessels, and serous cavities of the body; originates from mesoderm.
a membrane or sac that surrounds the heart
serous membrane that forms the innermost layer of pericardium and outermost layer of the heart.
irregular uncoordinated contraction of cardiac myocytes, either individually or in small goups.
the intrinsic ability of cardiac muscles to produce greater active force in response to stretch, a phenomenon known as length-dependent activation.
cause cellular damage. atoms or groups of atoms with an odd (unpaired) number of electrons and can be formed when oxygen interacts with certain molecules. They react with important cellular components.
localized areas of subendocardial fibrosis, usually in the atria, thought to be due to abnormal jets of blood by valvular lesions.
mineralization seen in areas of necrosis.
mineralization that happens when there is hypercalcemia in normal tissue.
a thick bundle of muscle in the central part of the right ventricle of the heart.
a small muscle within the heart that anchors the heart valve.
inflammation of a vein
a serious blood vessel disease in which small and medium sized arteries become swollen and damaged.
initial stretching of the cardiac myocytes prior to contraction due to volume overload.
refers to the pathological state of cardiac muscles in which it has to contract while experiencing an excessive afterload.
(non cancerous cardiac tumor) a benign tumor of striated muscle.
a blood clot that breaks off from a larger clot in the heart, travels down the aorta and lodges at the saddle.
occurs when the heart is unable to pump as much blood as the body needs.
the sudden and temporary loss of consciousness that is also described as fainting or passing out.
a faster than normal heart rate at rest.
swelling (inflammation) of a vein caused by a blood clot
irregular bundles and bands of muscle projecting from a great part of the interior walls of the ventricles of the heart.
the innermost layer of an artery or vein.
the middle layer of an artery or vein.
the strong outer covering (layer) of an artery or vein.
inflammation of blood vessels.
refers to the state of one of the chambers of the heart in which too large a volume of blood exists within it for it to function efficiently.
