概括

通过肌肉指数测量的心肌桥梁 (MB) 严重程度与接受冠状动脉计算机断层扫描血管造影的患者的左心室缩 (LVH) 有关. 这一发现表明MB和LVH之间存在潜在的关联.

科学领域:

心脏病学心脏病学
放射学放射学是一门学科.
医疗成像医学成像

背景情况:

心肌桥梁 (MB) 越来越多地通过冠状动脉计算机断层扫描血管学 (CCTA) 检测到.
虽然MB与心肌病相关,但其与左心室缩 (LVH) 的关联尚未得到充分证实.
了解这种关系对于评估心血管健康至关重要.

研究的目的:

调查心肌桥架 (MB) 严重程度和左心室缩 (LVH) 之间的关系.
评估冠状动脉计算机断层扫描血管学 (CCTA) 转诊的患者的MB.

主要方法:

通过640切片CCTA诊断出MB的227名患者的横截面研究.
使用MB肌肉指数 (MMI) 量化MB肌肉指数的严重程度.
左心室缩 (LVH) 通过 transthoracic心声学进行评估.

主要成果:

所有患者都存在心肌桥梁 (MB),通常在左前下降动脉上.
左心室缩 (LVH) 在36.1%的患者中被发现.
与没有LVH的患者相比,LVH患者的MB肌肉指数 (MMI) 显着更高 (P=0.022).
在左心室质量指数和MB长度 (r=0.414),MMI (r=0.310) 和年龄 (r=0.191) 之间发现了正相关性.

结论:

心肌架桥 (MB) 是CCTA检查中的一个常见发现.
心肌桥梁 (MB) 的严重程度与左心室缩 (LVH) 有显著的关联.
这些发现突显了MB严重程度和心脏重塑之间的潜在联系.

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Pathophysiology of Heart Failure

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...
