HF with reduced EF(HFrEF)射血分数降低性心衰/收缩性心衰 小于40% (HFmrEF)射血分数中间值的心力衰竭 40%--50% HF with preserved EF(HFpEF)射血分数保留性心衰/舒张性心衰 大于50% 二、病因及诱因 心输出量CO=每搏输出量SV×心率HR 每搏输出量SV取决于: 心肌收缩力、前负荷(舒张期容量)、后负荷(射血...
2022 AHA/ACC/HFSA指南仍然按照射血分数(EF)作为首次分类和再分类的标准,将心力衰竭分为“射血分数降低的心力衰竭(heart failure with reduced ejection fraction,HFrEF)”、“射血分数轻度降低的心力衰竭(heart failure with mildly reduced ejection fraction,HFmrEF)”以及“射血分数保留的心力衰竭(heart failure wit...
"There was a dose-response relationship between smoking and heart failure overall, as well as heart failure with reduced ejection fraction and heart failure with preserved ejection fraction," said Kunihiro Matsushito, MD, PhD, John Hopkins Bloomberg School for Public Health and John Hopkins Ciccar...
射血分数轻度降低的心力衰竭(heart failure with mildly reduced ejection fraction,HFmrEF):LVEF为41%~49%且有证据表明LV充盈压力增加; 保留射血分数的心力衰竭(heart failure with preserved ejection fraction,HFpEF):LVEF≥50%且有证据表明LV充盈压升高; HfimpEF:首次分类为HFrEF,再次测量LVEF>40% 。 所有目前或...
Left ventricular ejection fraction (EF)of 55%as cutoff for late transition from heart failure (HF)with preserved EF to HF with mildly reduced EF. Ueda T,Kawakami R,Nishida T,et al. Circulation Journal . 2015Ueda T, Kawakami R, Nishida T, Onoue K, Soeda T, Okayama S, et al. Left ...
This study sought to evaluate the influence of race/ethnicity on the relationship between body mass index (BMI) and mortality in heart failure with preserved ejection fraction (HFpEF) and HF with reduced EF (HFrEF) patients. Background Prior studies demonstrated an “obesity paradox” among overwei...
EF ejection fraction HF heart failure HFrEF heart failure with reduced ejection fraction LVEF left ventricular ejection fraction The etiology of heart failure (HF) has changed over time in more developed countries and is also evolving in less developed and other non-Western societies 1, 2, 3, 4...
Despite its initiated safety concerns, beta blockers are now one of the most used and safer drugs for the ailment of heart failure. These have proved not only effective for heart failure but also for many other conditions such as migraine headaches, breast cancer to reduce the mo...
2024年4月,美国心脏病学会(ACC)官方期刊《JACC: Heart Failure》刊登的研究《Cost-Effectiveness of Medical Therapy for Heart Failure With Mildly Reduced and Preserved Ejection Fraction》提出了重要见解。该研究通过精细的健康经济模型分析,评估了HFmrEF和HFpEF患者在接受当前推荐的药物治疗时的成本效益比。研究考虑...
Kelly toldtheheart.org|Medscape Cardiology, "Many of us in the heart failure community are very aggressive with rhythm control, particularly in patients with heart failure with a reduced ejection fraction. But this analysis specifically looks at patients with heart failure with preserved ejection frac...
