Plamna dynorphin Al-13 levels were measured in 33 patients with mitral stenosis before and afteT percutaneous balloon mitral eommimurotomy (PBMC). The results show that the basal levels of plasma dynorphin in blood from the antecubital vein in the patients were signifieantly higher than those in 31 healthy control subjects. The increase in circulating dynorphin closely correlated with the functional cardiac status and the presence of atrial fibrillation. Ten to fifteen minutes after PBMC, plasma dynorphln levels in blood from the femoral vein increased significantly. Seventy-two hours after the procedure, the levels of plasma dynorphin in blood from the anteeubltal vein had decreased significantly, but they did not decrease to the normal range. Plasmm dynorphin levels in blood from the femoral vein were positively correlated with the mean laft atrial pressure and the mean right atrial pressure before the first balloon inflation. Plasma dynorphin levels in blood from the anteeubital vein were positively correlated with the heart rate and the mean transmittal presstme gradient,and negatively with the mitral valve area before and 72 hours after PBMC. 相似文献

特发性心肌病是指病变主要位于心肌,也找不到其他疾病的关系,临床以心脏增大、心律失常、心力衰竭、血管栓塞为主要表现的心脏疾患。1880年世界卫生组织将本病分为三型,即扩张型(Dilated Cardiomyopathy,以下简称DCM)、肥厚型和限制型。在许多发展小国家该病约占心脏病的15%或以上。本病病因未明,有人报导部分病人的血清中有抗心肌抗体(Heart Muscle Antibody,HMA)存在,因而认为本病的发生可能是由于感染引起的心脏自身抗原抗体反应所致,可能是一种自身免疫性疾病。自从Masugi 1933年和Cavelti 1945年提出在某些心脏病中存在着抗心肌抗体以来,已 相似文献
