别嘌呤醇对慢性心力衰竭患者心功能的影响

目的 观察别嘌呤醇治疗慢性心力衰竭的临床效果.方法 选择2007年1月至2008年1月在我院住院的慢性心力衰竭患者56例,随机分成治疗组(别嘌呤醇组)和对照组(常规治疗组).常规治疗组:标准抗心衰治疗.别嘌呤醇组在常规治疗的基础上加用别嘌呤醇0.3 g/d,观察12周.两组均于治疗前以及治疗12周后由专人用超声心动图测左室射血分数(LVEF)、左室收缩末容量指数(LVESVI),测量治疗前及治疗12周后血清尿酸浓度.结果 别嘌呤醇组在血清尿酸浓度明显减少,心功能得到明显改善,而常规治疗组无显著变化.结论 在标准抗心衰治疗的基础上加用别嘌呤醇(0.3 g/d)能给慢性心力衰竭患者带来益处.

Tackling heart failure in the twenty-first century

Heart failure, or congestive heart failure, is a condition in which the heart cannot supply the body's tissues with enough blood. The result is a cascade of changes that lead to severe fatigue, breathlessness and, ultimately, death. In the past quarter century, much progress has been made in understanding the molecular and cellular processes that contribute to heart failure, leading to the development of effective therapies. Despite this, chronic heart failure remains a major cause of illness and death. And because the condition becomes more common with increasing age, the number of affected individuals is rising with the rapidly ageing global population. New treatments that target disease mechanisms at the cellular and whole-organ level are needed to halt and reverse the devastating consequences of this disease.
