对于左心室扩张功能障碍 (LVDD) 的异常心声学参数,即使存在轻微功能下降,也存在. 随着功能下降,LVDD异常的风险显著增加.
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學.
- 诊断成像 诊断成像 诊断成像
背景情况:
- 左心室扩张性功能障碍 (LVDD) 经常与慢性病共存.
- 声心图对于评估心脏功能,包括透静功能至关重要.
研究的目的:
- 调查功能不同阶段与LVDD的指标心声学参数之间的关联.
- 为了确定LVDD异常在估计膜过率 (eGFR) 的不同水平的患病率.
主要方法:
- 追溯分析4022名患者的可用血清肌素和心声回声数据.
- 根据eGFR,患者被分为四组:正常 (≥90),轻度 (60-90),中度 (30-60),严重 (<30毫升/分钟/1.73米2).
- 使用后勤和线性回归分析来评估功能和LVDD参数之间的关系.
主要成果:
- 在功能的所有阶段观察到异常的LVDD回声心脏学参数,包括E/e'比,左心房体积指数 (LAVI),TR速度和左心室质量指数 (LVMI).
- 患有轻微功能下降的患者表现出异常E/e'比率的几率增加 (OR: 1.51).
- 患有中度和重度功能障碍的患者表现出多个LVDD异常的几率显著更高,eGFR和LVDD参数之间明显的反向关联.
结论:
- 即使在功能障碍的早期阶段,LVDD的心声学证据也可以检测到.
- 功能逐渐下降与LVDD的风险和严重程度逐步增加有关.
- 这些发现强调了心脏和脏健康的相互联系,以及心脏查对患有脏疾病的患者的重要性.

Heart Failure Drugs: Diuretics
350
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Factors Affecting Renal Clearance: Renal Impairment
62
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
