概括

较高的脚跟骨矿物质密度 (eBMD) 与心血管疾病 (CVD) 风险和死亡率的降低有关. 然而,基因分析并未证实骨密度与心脏病之间的直接因果关系.

科学领域:

心血管健康心血管健康
骨的新陈代谢骨的新陈代谢
流行病学流行病学

背景情况:

心血管疾病 (CVDs) 构成了全球健康的重大负担.
已观察到骨矿物质密度 (BMD) 与心血管健康相关.
了解 BMD 和 CVD 之间的关系对于公共健康至关重要.

研究的目的:

调查估计的脚骨矿物质密度 (eBMD) 与流行/发生心血管疾病之间的关联.
检查eBMD与全因,心血管疾病和缺血性心脏病 (IHD) 死亡率之间的关系.
评估eBMD与心血管磁共振 (CMR) 测量之间的联系.

主要方法:

利用了来自485,257名参与者的英国生物库数据.
使用定量超声波进行eBMD估计.
进行了前性后续和门德尔随机化 (MR) 分析.

主要成果:

较高的eBMD与较低的流行心血管疾病的几率相关,特别是心力衰竭 (HF) 和非缺血性心肌病 (NICM).
较高的eBMD与减少全因,心血管疾病和IHD死亡率有关.
观察数据显示,更高的eBMD与更大的大动脉延伸性有关,但MR分析不支持因果关系.

结论:

高跟鞋的eBMD与普遍和偶发性心血管疾病和死亡率的风险降低有关.
这些发现表明共享的风险因素,而不是骨和心血管健康之间的直接因果关系.
需要进一步的研究来阐明骨密度和心血管结果之间的复杂相互作用.

Osteoclasts in Bone Remodeling

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
