Draw back narrow pericarditis complication and first _ symptom
1.The chronic heart is pressed and filled in Draw back the stiff degree of increase because of chronic inflammation of pericardium of the narrow pericarditis, the pericardium can't expand and press and press and rise in the heart notably in the pericardium, in the pericardium when the pressure rises and reaches atrium dextrum and right ventricle diastolic pressure level, the heart keeps dropping and closes to zero across the wall, press and fill in the pericardium. 2.Source liver cirrhosis of heart Accounts for 16.6% that all heart sources hardened; Because is chronic while drawing back narrow pericarditis, the plump, stiff pericardium limits the heart plentifully, make diastolic pressure and atrium dextrum of right ventricle press and raise, the intravenous reflux blockage of liver, the blood flow delays in time when staying in intravenous sinus of liver. In addition, the cardiac output is reduced, blood and oxygen saturation lever is reduced, oxygen content of central district of small leaf of the liver is further reduced, this district hepatocyte wither so that disappear, form netted subside and fiber of support organize hyperplasia in the liver slowly. With extension of time, fiber take, develop towards small neighbouring leaf and until fibrous organization join each other around the neighbouring central vein, surround original pieces of pulse district, form the small abnormal leaf, this pathological change is considered to be the pathologic characteristic of source liver cirrhosis of heart. The oxygen deficiency of hepatocyte is slow but incomplete while drawing back narrow pericarditis, so no acute and extensive necrosis or a large amount of necrosis will happen, the inflammatory response is relatively light, there is no hyperplasia of obvious hepatocyte. 3.The lung artery is narrow Chronic to draw back narrow pericarditis, because of the positions (the ditch department of room room) of four rings of heart Move in one degree of largest positions for the heart. The pericardium wall here, dirty friction of storey are the greatest at the time of pericarditis, therefore the inflammatory response is strong, fiber, calcification incident, even belt band, reduce drawing back the function easily of the heart. So pericarditis can be similar to lung artery narrow clinical manifestation and dynamics of blood flow to change.
