心脏收缩性调制 (CCM) 疗法可以长期稳定心力衰竭患者的功能. 患者心脏功能有所改善,但功能受损表明心力衰竭并发症的风险更高.
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 医疗器械 医疗器械
背景情况:
- 心脏植入式电气设备可以通过血液动力学变化影响功能.
- 心脏收缩性调制 (CCM) 是一种治疗慢性心力衰竭 (HF) 患者的疗法,患者对医疗治疗没有反应.
- 需要进一步调查CCM治疗的长期心脏和脏效应.
研究的目的:
- 评估CCM治疗对心力衰竭患者功能的长期 (长达60个月) 影响.
- 为了比较晚期慢性病 (aCKD) 和保存或轻度CKD (pCKD) 的患者之间的功能变化.
- 评估基线功能和CCM后的HF并发症之间的关系.
主要方法:
- 该研究分析了60个月的MAINTAINED研究中的187名CCM接受者.
- 使用血清肌素和估计的淋巴细胞过率 (eGFR) 监测功能.
- 为了进行比较,患者被分为aCKD (eGFR ≤59 mL/min/1.73 m2) 和pCKD (eGFR ≥60 mL/min/1.73 m2) 的两组.
主要成果:
- 在60个月的随访期间,CKD阶段分布保持稳定.
- 在60个月后的总队列中观察到eGFR的轻微但显著下降,主要是在pCKD组中.
- 在两组中,CCM治疗导致NYHA分类和LVEF显著改善.
- 患有CKD的患者经历了更多的HF住院和腹腔心动力障碍.
结论:
- 在心力衰竭患者中,CCM疗法可以长期保持稳定的功能和CKD阶段.
- 无论基线功能如何,都观察到LVEF和功能状态的改善.
- 在CCM患者中,先前存在的功能受损可能与心血管并发症的增加和HF并发症风险的增加有关.

Factors Affecting Renal Clearance: Renal Impairment
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...
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
