Efficacy of stents is improved when their placement is determined by arterial blood flow measurement
Date:2/6/2009

afen, Germany, said that, while PCI is clearly beneficial for the relief of symptoms in patients with stable angina, the prognostic impact of PCI in the patient group in this study is still a matter of debate. One reason for this, he explained, may be that some stent procedures are performed solely on the basis of "oculo stenotic reflex" (the visual presence of a stenosis).

However, he added: "One method which is easy to perform and readily available during diagnostic angiography is measurement of the fractional flow reserve, a method which can distinguish between hemodynamically relevant and irrelevant stenoses. The latter do not need intervention and can be safely treated with medical therapy. The FAME study has now shown that by using FFR we can improve the prognosis of patients and reduce the number of unnecessary interventions. As a result, this method should be used in patients with stable symptoms and without documentation of ischemia by another method. In patients with multivessel disease in particular, FFR can increase the safety and efficacy of coronary revascularisation. In addition, FFR seems cost effective and avoids unnecessary and potentially harmful interventions."
