定义:心力衰竭(Heart Failure, HF):是各种原因引起心脏结构或功能改变,导致心室充盈和(或)射血功能受损,心排血量不能满足机体组织代谢需要,以肺循环和(或)体循环淤血,器官、组织血液灌注不足为临床表现的一组综合征,主要表现为呼吸困难、体力活动受限和体液储留。 分类 按部位 左心衰:肺循环淤血 左心泵血减少→...
The NYHA functional classification of heart failure is widely used in practice and in clinical studies. It is based on symptom severity and the amount of exertion needed to provoke symptoms. NYHA heart failure classes are as follows [2] : Class I: No limitation of physical activity Class II...
HF: heart failure JVD: jugular venous distention New York Heart Association (NYHA) functional classification[1,2,13,22] This system classifies cases based on the degree of effort to evoke breathlessness but does not correlate with the degree of cardiac structure abnormalities. Class I: no limita...
Cardiac resynchronization therapy (CRT) reduces morbidity and mortality in patients with heart failure (HF) with reduced ejection fraction (HFrEF) and electrical dyssynchrony but outcome effects of CRT in pacing-induced HF have...
‘shunt creation’ with the use of dedicated shunt device successfully attenuated the exercise-induced elevation in LA pressure and it showed favourable trends in several haemodynamic and functional end points for patients with ...
All patients were receiving treatment and had had symptoms of heart failure with NYHA functional class II or III. Patients had a significantly higher body mass index compared with control subjects, but VO2max, which accounted for body mass index and age, was significantly lower in patients ...
In a cohort of more than 300 HF patients, more than 90% reported reduced libido and erectile problems, which was independent of the New York Heart Association (NYHA) functional class (our data, unpublished). In our own chronic HF population, at least 75% of patients admitted to experiencing...
infarction and were more likely to be previously hospitalized for HF or had implantable cardioverter defibrillators (ICDs). Those with HFimpEF generally carried a diagnosis of HF for longer and were more likely to have New York Heart Association (NYHA) functional class II (versus III and IV) ...
Further studies also revealed that linear HRV were associated with volume status, functional class of HF, LVEF, serum norepinephrine and tumor necrosis factor level in HF patients28,29,30,31. Furthermore, functional test and the alternation of heart loading condition also interfere the diagnostic ...
