概括
在接受levosimendan治疗的晚期心力衰竭患者中,高N终端脑前性尿素水平 (> 6000 pg/mL) 预测了更差的生存率. 其他基线特征并没有显著影响该队列的死亡率结果.
科学领域:
- 心脏病学 心脏病学
- 临床医学 临床医学
- 药理学 药理学是指药理学的学科.
背景情况:
- 晚期心力衰竭 (AHF) 提出了复杂的管理挑战.
- 间歇性无otropics,如levosimendan,用于改善AHF的症状和结果.
- 确定生存预测因素对于优化患者护理至关重要.
研究的目的:
- 为了确定基线临床特征是否预测AHF患者接受间歇性levosimendan.
- 为了评估年龄,NYHA类,LVEF,GFR,SBP和NT-proBNP的预后值.
主要方法:
- 对42名AHF患者进行了回顾性生存分析,这些患者接受了levosimendan治疗.
- 卡普兰-梅尔曲线和日志等级测试被用来评估生存率.
- 评估的基线特征包括年龄,NYHA类,LVEF,GFR,SBP和NT-proBNP.
主要成果:
- 39.5%的患者在1年的随访期间死亡.
- 较高的NT-proBNP水平 (>6000 pg/mL) 与明显更差的生存率有关 (HR: 2.72; P=0.0493).
- 根据GFR,LVEF,SBP,NYHA类或年龄,没有观察到显著的生存差异.
结论:
- >6000 pg/mL的NT-proBNP水平可能是接受levosimendan的AHF患者生存率低下的关键预测因素.

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

01:27Heart Failure I: Introduction
55
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...
