观察组与对照组再住院率比较,观察组再住院病人4例,再住院率为5.0%;对照组再住院病人8例,再住院率为10.0%;经χ2检验分析,观察组在再住院率上低于对照组(P<0.01)。由于两组总例数和死亡例数较少,观察时间较短,因此,死亡率统计分析意义不大。 表1 治疗6个月后观察组与对照组运动及气体代谢指标的比较 (略) 表2 治疗6个月后观察组各项运动及气体代谢指标的比较 (略) 3 讨论 4 小结 [参考文献] 1 Esler M,Kaye D,Lambert G,et al.Adrenergic nervous system in heart failure.Am J Cardiol,1997,80:7-14. 2 Bristow MR.Mechanism of action of beta-blocking agents in heart failure.Am J Cardiol,1997,80:26-40. 3 Colucci W.Molecular and cellular mechanisms of myocardial failure.Am Cardiol,1997,80:15-25. 4 Mckee PA,Castell WP,McNamara PM,et al.The natural history of congestive heart failure,the framingham study.N Engl J Med,1971,285:1441-1448. 5 Maranti PR,Tobin JN,Wassertheil-Smoller S,et al.The relationship between left ventricular systolic function and congestive heart failure diagnosed by clinical criteria.Circulation,1998,77:607-614. 6 Criteria Committee,New York Heart Association,Inc.Diseases of the heart and blood vessels.Nomenclature and criteria for Diagnosis.6thed Boston little Brown and Co,1964,p114-120. 7 Bristow MR.Mechanism of action of beta-blocking agents in heart failure.Am Cardiol,1997,80:26-40. 8 Colucci W.Molecular and cellular mechanisms of myocardial failure.Am J Cardiol,1997,80:15-25. 9 Thomas JA,Marks BH.Plasma norepinephrine in congestive heart failure.Am J Cardiol,1978,41:233-243. 10 Cohn JN,Levine B,Olivari T,et al.Plasma norepinephrine as a guide to prognosis in patients with congestive heart failure.N Engl J Med,1984,311:819-823. 11 Lechat P,Packer M,Chalon S,et al.Clinical effects of β-adrenergic blokade in chronic heart failure.Circulation,1998,98:1184-1191. |
