预防性穿皮冠状动脉干预与治疗脆弱动脉硬性冠状动脉斑块 (PREVENT) 的最佳药物治疗:多中心,开放,随机对照试验
在PubMed上查看摘要
概括
此摘要是机器生成的。预防性穿皮冠状动脉干预显著降低了非流量限制的脆弱斑块患者的重大心脏不良事件. 与单独的最佳药物治疗相比,这种针对脆弱斑块的焦点疗法在预防心脏事件方面具有前景.
科学领域
- 心脏病学
- 干预心脏病学
- 预防性心脏病学
背景情况
- 易受伤害的斑块,通常不限制流动,是急性冠状动脉综合征和突然心脏死亡的主要原因.
- 对这些特定斑块的预防性穿皮冠状动脉干预 (PCI) 的疗效在很大程度上尚未确定.
- 评估预防性PCI在高风险,不限制流动的脆弱斑块中的作用对于改善患者的结果至关重要.
研究的目的
- 评估预防性穿皮冠状动脉干预 (PCI) 与单独的最佳医学治疗 (OMT) 的有效性.
- 确定非流量限制的脆弱斑块的PCI是否可以减少心脏不良事件.
- 在高风险患者队列中比较PCI加OMT和单独OMT的临床结果.
主要方法
- 一个多中心的,开放的,随机对照试验 (PREVENT) 涉及1606名患者.
- 患有非流量限制的脆弱斑块 (FFR>0. 80) 的患者随机分为PCI+OMT或单独OMT.
- 主要结局是2年后心脏死亡,目标血管性心脏病发作,再血管化或不稳定的心痛住院.
主要成果
- 与单独使用OMT相比,预防性PCI显著降低了初级复合结果 (0. 4%与3. 4%,p=0.0003).
- 在两年内,两组之间没有发现严重不良事件 (包括死亡或心肌梗塞) 的显著差异.
- 预防性PCI的积极效果与主要综合结果的所有组成部分一致.
结论
- 预防性穿皮冠状动脉干预是有效的减少主要心脏不良事件的患者没有流量限制的脆弱斑块.
- 这些发现支持考虑扩大PCI指示,包括高风险,不限制流量的易受损害的斑块.
- PREVENT 试验提供了第一个针对易受损伤的焦点治疗的大规模证据.

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...
Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...
