BACKGROUND.: A high homocysteine level is associated with an increased risk of ischaemic heart disease. Folate therapy has shown to reduce the homocysteine blood level, but does it decrease the risk of coronary restenosis in patients with coronary arterial disease? METHODS.: A systematic online literature search followed by a critical appraisal resulted in three suitable articles to provide an evidence-based evaluation of this clinical query. RESULTS.: The rate of coronary restenosis was reduced after folate therapy, except in patients who have had coronary stenting. An adverse effect of folate therapy on in-stent coronary restenosis was observed. CONCLUSION.: The effects of folate therapy on the rate of coronary restenosis after balloon angioplasty are contradicting. Until more clinical research has been preformed we recommend a conservative attitude towards folate therapy. (Neth Heart J 2007;15:12-5.).
高同型半胱氨酸水平与缺血性心脏病的风险增加有关。叶酸治疗已被证明可降低血液同型半胱氨酸水平,但它是否会降低冠状动脉疾病患者的冠状动脉再狭窄风险?
系统的在线文献检索,随后进行批判性评估,得出了三篇合适的文章,为这一临床问题提供了循证评估。
除了接受冠状动脉支架植入术的患者外,叶酸治疗后冠状动脉再狭窄的发生率降低。观察到叶酸治疗对支架内冠状动脉再狭窄有不良影响。
叶酸治疗对球囊血管成形术后冠状动脉再狭窄率的影响存在矛盾。在进行更多的临床研究之前,我们建议对叶酸治疗持保守态度。(荷兰心脏杂志 2007 年;15:12-5.)。
