概括
直接口服抗凝剂 (DOAC) 对心房动 (AF) 和功能下降的八岁以上患者是安全有效的. 与维生素K对抗剂 (VKA) 相比,DOACs在这个患者群体中死亡率较低.
科学领域:
- 心脏病学 心脏病学
- 药理学 药理学是指药理学的学科.
- 腎臟病學 (nephrology) 是一種醫學專業.
背景情况:
- 心房动 (AF) 在老年人中很常见,通常与慢性病 (CKD) 并存.
- 口服抗凝剂 (OAC) 对于AF患者的中风预防至关重要,但其在八岁以上的不同功能患者的使用需要仔细考虑.
- 直接口服抗凝剂 (DOAC) 和维生素K抗剂 (VKA) 是主要的OAC选择,每种药物在患有功能障碍的老年人群中都具有不同的疗效和安全性.
研究的目的:
- 评估OACs的疗效和安全性,特别是DOACs与VKAs,在被诊断为AF的八十岁以上 (年龄≥80岁) 人群中.
- 分析不同功能水平的OAC结果,按肌素清除量 (CrCl) ≥45mL/min/1.73m2和<45mL/min/1.73m2.2进行分类.
- 为了确定与高风险患者队列中死亡率相关的因素.
主要方法:
- 来自AF研究数据库 (NCT03760874) 的901名80岁以上的AF患者的回顾性分析.
- 患者接受了DOAC (n=629) 或VKA (n=272) 的治疗,并以CrCl分层:≥45mL/min/1.73m2 (n=598) 或<45mL/min/1.73m2 (n=303).
- 主要结局包括主要出血事件 (安全性) 和血栓塞栓事件 (有效性). 还评估了死亡率和特定出血事件,如内出血 (ICH). 多变量回归被用于关联分析.
主要成果:
- 在功能组中,在DOAC和VKA之间没有观察到重大出血或血栓栓塞发事件的显著差异.
- 在CrCl<45mL/min/1.73m2的患者中,与DOAC (15%) 相比,VKAs (45%) 的死亡率明显高于DOAC (15%).
- 在CrCl≥45mL/min/1.73m2的患者中,DOAC与VKA相比,与较少的ICH (0.2%对2.8%) 和较低的死亡率 (7.9%对29.1%) 相关. 年龄和冠状动脉疾病与较高的死亡率有关,而DOAC使用与功能组的死亡率相反相关.
结论:
- DOACs在八十多岁的AF和CKD阶段≥G3b (CrCl <45mL/min/1.73m2) 的八十多岁患者中证明了安全性和有效性.
- 与VKAs相比,DOAC的使用与老年AF患者的功能障碍的死亡率降低有关.
- DOACs代表了80多岁的AF和不同程度的功能障碍患者的有利OAC选择,特别是在功能下降的患者中.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants
1.2K
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Renal Failure: Dose Adjustments
95
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
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...

Anticoagulant Drugs: Low-Molecular-Weight Heparins
708
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Factors Affecting Renal Clearance: Renal Impairment

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...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
436
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Antihypertensive Drugs: Direct Renin Inhibitors
632
The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...
