【摘要】 观察76例心房纤颤患者,发现色氨酸(Trp)、5—羟色胺(5—HT)、5—羟吲哚乙酸(5—HIAA)、酪氨酸(Tyr)、去甲肾上腺素(NE)、多巴胺(DA)均比对照组明显增高(P<0.01)。5—HT在阵发性房颤组中增高较持续性房颤组更显著(P<0.01)。而Tyr则在持续性房颤组中增高明显(P<0.05)。房颤并发心襄组Tyr、NE、DA增高比不并发心衰组更明显,P值分别为<0.02、<0.01、<0.05。房颤并发感染的5—HT、Tyr、NE升高比不并发感染更显著,P值分别为<0.01、<0.05、<0.05。更多还原

【Abstract】 76 Casee of atrial fibrillation(AF) were studied for changes in plasma monoamines system. The mean values of plasma monoamines were found significantly higger in AF than in controlled healthy gtoups(P<0.01). Plasma 5-HT was even higher in paroxysmal AF than in sustained AF (P<0.01), whereas tyrosine (TYr)was higher in sustained. AF than in paroxysmal AF (P<0.05). In cases associated with heart failure, the raise in TYr, norepinephfine (NE), dopamine (DA) levels was more significant than in those without (P<0.01, <0.01, <0.05 respectivly). Similarly in AF complicated with respiratory infections the plasma 5-HT, TYr, NE were markedly higher than in those without such complications (P<0.01, <0.05, <0.05 respectively)更多还原
