For example, in recent years, a number of studies have demonstrated that the presence of coronary microvascular disease (CMVD) contributes to increased cardiovascular morbidity and mortality independent of the extent and severity of coronary epicardial disease. The index of microcirculatory resistance (IMR) is an invasive index proposed for the diagnosis of CMVD. The ability of IMR to motivate therapeutic changes in order to subsequently reduce symptoms and improves the quality of life of our patients with stable coronary artery disease (CAD) was recently demonstrated. The prognostic value of IMR has also been shown in stable CAD with PCI. Thus, after optimal epicardial evaluation and if necessary revascularization according to FFR, IMR could represent a tool for personalized medicine adapted to the presence of severe CMVD.\n\nThe aim of the study is to demonstrate a positive effect of personalized medicine on angina in patients with epicardial coronary network lesion assessment by FFR and with significant CMVD assessed by IMR.",[73],"Coronary Microvascular Disease",[75],"index of microcirculatory resistance","2024-06-21",{"date":78,"type":79},"2024-06-24","ACTUAL",{"date":81,"type":79},"2022-03-31",{"date":83,"type":67},"2026-03",{"name":5,"class":6},1]
