Is heart failure with midrange ejection fraction similar to preserved ejection fraction? Against.
The new European guidelines (2016) for heart failure (HF) include the concept of HF with intermediate left ventricular ejection fraction (LVEF), i.e. an LVEF between 40 and 49%. Although few studies have been carried out, there are claims that HF with intermediate LVEF is not the same as HF with preserved LVEF. Perhaps the most consistent claim is the high percentage of associated ischemic heart disease, which could reflect LVEF recovery after adequate anti-ischemic treatment of HF with depressed LVEF, or even the progressive deterioration of LVEF following an ischemic event.
