Researcher's Work from First Hospital of Lanzhou University Focuses on Heart Disease (Clinical value of fractional flow reserve in coronary heart disease: A retrospective study).

A study conducted at the First Hospital of Lanzhou University in China focused on the clinical value of coronary arteriography (CAG) combined with fractional flow reserve (FFR) in treating coronary heart disease (CHD) with coronary artery stenosis exceeding 70%. The retrospective analysis included 344 patients with CHD, with findings indicating that the CAG + FFR group showed a 44.72% reduction in the need for surgical treatment and a decreased number of stents placed, helping to prevent overtreatment. The research concluded that FFR could significantly prevent overtreatment and provide more precise guidance for CHD treatments. [Extracted from the article]
