Draw back narrow _ general knowledge of pericarditis
Contract getting narrow pericarditis hard and stiff surrounding by pericardium that fiber take thick for the intersection of pericardium and heart behind the inflammation, influence the ventricle to be normal and plentiful, energies of answering quantity is reduced, cause the heart to arrange blood volume and reduce a series of clinical manifestation of circulating the obstacle of increasing with venous pressure etc., the morbidity accounts for 1.6% of the total number of heart disease.
Cause of disease
Caused by tuberculosis, suppurative and non- specific pericarditis partly, seeing after pericardium traumatism too or patient of rheumatoid arthritis. Have a lot of contract getting narrow the intersection of pericarditis and patient organize inspection can't confirm cause of disease their either by the intersection of pericardium and pathology. It can cause a disease that pericardium tumour and radiotherapy are even.
Pathology and pathologic physiology
Contract in narrow pericarditis, the dirty storey of pericardium and wall, one storey of extensive adhesions, increasing the thick and calcification, but reach 0.5cm thick, the pericardium stops up the outer cover organized as a fibrous scar, charter shelter and the oppression whole hearts and trunk exits tightly. Pathological change is very serious on a certain position sometimes, such as the room room ditch, superior vena cava entry or and wall of the chest, separate and take place the extensive adhesion sideways, after can find the tuberculosis suppurative infection in some patients' pericardium tissueing, the granulation is organized, been hard, increased thick and drawing back the narrow pericardium cicatrix and oppressing the heart, expansion in the relaxation one of restriction ventricle, the blood which enters the ventricle is reduced, therefore the heart arranges blood volume low. The heart can cause the kidney to make the blood capacity increase to retention of the salt and water while arranging blood volume and reducing. Meanwhile, drawing back the narrow pericardium makes a blood reflux of relaxation become difficult while entering the heart, appear venous pressure rise, intravenous the intersection of anger and piece this, the intersection of liver and swelling, ascites, the intersection of chest and the intersection of ink, lower extremities edema,etc. and physical sign. Left heart especially atrium sinistrum are drawn back narrow influence, can cause the lung to be congested, have difficulty in breathing.
Get up disease hide, pericardium contract narrowly to take place several year on several months such as acute pericarditis often. The patient has dyspnea, belly swelling, weak, dizzy, stomach at various degrees to receive failing, coughing, weight to lighten and pain etc. in the liver district. Common physical sign is difficult to touch to beat for the apex of the heart, the heart voiced sound circle increases normally and slightly, the first sound is lowered, hear the early extra sound of the first relaxation among ribs third, four of left reason of brestbone sometimes, sonority change great, present, make person who hit gratified bag knock, hit transliteration sometimes. Mainly because the ventricle can't press sufficient relaxation, the blood of atrium is early at ventricle relaxation to enter the ventricle rapidly, and then the vibration that the unexpected stop causes and sound that produces. The heart rate is very fast, there can be beating, atrium fluttering or auricular fibrillation,etc. too early. The heart is pressed and the intravenous reflux blockage can present; The intersection of neck and intravenous the intersection of anger and piece, and anger one more obvious while inhaling, only relaxation can see and collapse (Friedreich solicits) in early period . Liver swelling, ascites, the intersection of lower extremities and edema, ascites the intersection of lower extremities and edema appear early obvious relatively, the systolic pressure of artery is reduced, the pulse pressure is low, there is strange pulse,etc.. Venous pressure is determined to increase notably, often exceed 2.45kpa(250mmH2O)
