本文从血液动力学角度探讨了老年人贫血的代偿机理和心脏疾病方面的代偿失调,以及贫血时的特异性心血管合并症。 方法:用染料稀释法测定了正常老年人(30例)、贫血病人(30例)和有心脏病的贫血病人(29例)的血液动力学变化。对12例贫血伴有心血管合并起病人进行了临床病理学探讨。 结果.贫血病例血球容积(Ht)为21.4,心脏指数(升/分/米~2)平均为4.43,与正常老年人
This paper explores the compensatory mechanism of anemia in the elderly and the decompensation of heart disease from the hemodynamic point of view, as well as specific cardiovascular complications during anemia. Methods: The hemodynamic changes of normal elderly (30 cases), anemic patients (30 cases) and anemic patients with heart disease (29 cases) were determined by dye dilution method. Clinicopathological study of 12 patients with anemia associated with cardiovascular complications. Results Anemia patients had a hematocrit (Ht) of 21.4 and an average heart index (L / min / m ~ 2) of 4.43,
