文中指出心力衰竭(HF)的通用定义:心力衰竭是一种临床综合征,其症状和/体征由心脏结构和/或功能异常引起,并由利钠肽水平升高和/或肺部或全身充血的客观证据所证实。并根据左室射血分数(left ventricular ejection fraction, LVEF)提出一种新的心衰分类方法。 HF新...
In heart failure with reduced ejection fraction (HFrEF—sometimes called systolic heart failure): The heart contracts less forcefully and pumps out a lower percentage of the blood that is returned to it. As a result, more blood remains in the heart. Blood then accumulates in the lungs, veins...
A clinically useful classification of the syndrome is,patients with left ventricular systolic impairment (Heart Failure and reduced ejection fraction, HFREF) and patients with preserved left ventricular systolic function (HFPEF). The pharmacological treatment for patients with HFREF has evolved over the ...

population, thus counting around 36 million of individuals globally; it consists of a chronic and progressive syndrome characterized by structural or functional cardiac dysfunctions with reduced (HFrEF; < 40%) or preserved (HFpEF; ≥ 50%) left ventricular ejection fraction [1, 2, 3, 4...

intensive care unit in the alert and usual-care groups, respectively. A total of 367 patients (23.1%) and 359 patients (23.4%) had a left ventricular ejection fraction of 40% or less in the alert and usual-care gr...
E) AICD recalibration Answer: D This patient has multiple indicators for the definition of advanced chronic heart failure, including symptom-based high New York Heart Association (NYHA) classification, severe chronic obstructive pulmonary disease, and left ven- tricular ejection fraction below 30 %. ...
The contribution of clinical inertia to suboptimal guideline-directed medical therapy (GDMT) for patients with heart failure with reduced ejection fraction (HFrEF) remains unclear. This study examined reasons for GDMT nonintensification and characterized clinical inertia. In this secondary analysis of EPIC...
