Endocarditis, Pericarditis and Myocarditis Endocarditis Most of endocarditis caused by viridans streptococci are microorganisms that live in the upper airway. Prior to the discovery of antibiotics, then 90-95% of endocarditis infection, caused by viridans streptococci , but since the presence of antibiotics, viridans streptococci cause infective endocarditis 50%, which is 1/3 of the source of infection. Another cause of infective endocarditis is more pathogens are Staphylococcus aureus , which causes subacute infective endocarditis. Other causes include fecal streptococci , staphylococci , gram-negative aerobic / anaerobic, fungi, viruses, yeast, and candida. Pericarditis 1) The cause of idiopathic or nonspecific. 2) Infection Bacteria: Streptococcus, staphylococcus, meningococcus, gonococcus . Viruses: coxsakie, influenza. Fungi: rickets, parasites. 3) connective tissue disorders - systemic lupus erythematosus, rheumatic fever, rheumatoid arthritis, polyarteritis. 4) The state of

Endocarditis, Pericarditis and Myocarditis Endocarditis Endocarditis is an infection of the heart valves and the endothelial surface caused by the direct invasion of bacteria or other organisms and cause deformity of the valve blade. Causing microorganisms including bacteria ( streptococci, enterococci, pneumococci, staphylococci ), fungal, rickettsial, and viridans streptococci . Infectious endocarditis is common in the elderly may be due to decreased immunological response to infection, metabolic changes due to aging and the increase of invasive diagnostic procedures, particularly in genitourinary disease. Pericarditis Pericarditis is an inflammation of the parietal pericardium, the visceral pericardium, or both. Pericarditis is divided up; Acute pericarditis, subacute pericarditis, and chronic pericarditis. Subacute and chronic pericarditis have etiology, clinical manifestations, diagnostic approaches, and management of the same. Classification of pericarditis, both clinically and t

Cardiovascular system is a system that gives facilities the transport of a variety of substances, and to the body's cells. The system consists of a driving organ called the heart, and the channel system consisting of an artery that carries blood from the heart, and veins that supply blood to the heart. The human heart is a hollow heart has two atria and two ventricles. The heart is a muscular organ that is able to push the blood to various parts of the body. The human heart is shaped like a cone and the size of a fist, located on the left hand of the chest cavity. The heart is covered by a membrane called the pericardium. The heart is responsible for maintaining the flow of blood with the help of a number of valves that make it up. To assure the continuity of the circulation, the heart contracts periodically. The heart muscle to contract continuously without experiencing fatigue. Contraction of the human heart is a myogenic contraction, the contraction begins excitatory strength of
