本文用荧光法测定了老年慢性肺源性心脏病发作期病人血清过氧化脂质(LPO)40例,老年前期慢性肺心病发作期病人25例,对照组53例。结果表明,老年慢性肺源性心脏病和老年慢性肺心病合并冠心病两组病人在发作期血清LPO显著高于对照组(P<0.05)。老年期与老年前期比较差异不显著(P>0.05)。单纯肺心病与肺心病合并冠心病组比较亦无显著差异(P>0.05)。但严重心衰伴呼衰的晚期肺心病人,血清LPO有显著下降趋势。 In this paper, 40 cases of elderly patients with chronic cor pulmonale were detected by fluorescence spectrometry. Serum lipid peroxides (LPO) were detected in 40 elderly patients with chronic cor pulmonale and 25 in control group. The results showed that the serum LPO levels in elderly patients with chronic cor pulmonale and elderly patients with chronic cor pulmonale and coronary heart disease were significantly higher than those in control group (P <0.05). There was no significant difference between old age and old age (P> 0.05). Pulmonary heart disease and pulmonary heart disease with coronary heart disease group also showed no significant difference (P> 0.05). However, severe heart failure with respiratory failure in patients with advanced pulmonary heart, serum LPO decreased significantly.
