概括

心肌工作指数 (MWI) 在异常缩 (EH) 和正常几何体质的耐力运动员之间没有差异. 运动员的EH与更高的VO2max有关,这表明MWI可能有助于区分生理适应和病理变化.

科学领域:

心脏病学
运动医学
生理学

背景情况:

耐力运动员经常表现出心脏重塑,特别是古怪的缩 (EH),可以模仿病态状况.
区分生理适应和潜在心肌病对于运动员的健康至关重要.
心肌工作指数 (MWI) 显示出区分这些疾病的潜力,但运动员的数据有限.

研究的目的:

在精英耐力运动员的队列中描述MWI.
研究运动员MWI与心脏几何之间的关系.
评估MWI在区分生理心脏重塑与潜在病理方面的有用性.

主要方法:

153名奥运会耐力运动员接受了心肺运动测试 (CPET) 和胸腔心声扫描 (TTE).
运动员根据心脏几何形状进行分类:异常增高 (EH) 与正常几何形状 (NG).
包括全球工作指数,全球建设性工作,全球浪费工作和全球工作效率在内的MWI与应变率和CPET参数一起进行了评估.

主要成果:

87名运动员 (56. 9%) 患有EH,而66名 (43.1%) 患有NG;训练量在两组之间相似.
在患有EH和NG的运动员之间没有发现MWI参数的显著差异.
运动员表现出更高的功能能力,在CPET期间VO2max和O2脉冲增加,心律失常负担相似.

结论:

在耐力运动员中, 奇特的重塑是普遍存在的,
在这个队列中,MWI没有区分EH和正常几何.
运动员中VO2max和O2脉的增加表明了生理适应,支持MWI在运动员中良性与病态心脏变化的区分方面的潜在作用.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Pathophysiology of Cardiac Performance

Pathophysiology of Cardiac Performance

Typical heart performance is influenced by heart rate, rhythm, myocardial contraction, and metabolism or blood flow. The cardiac muscle exhibits distinct electrophysiological features, including pacemaker activity and calcium channel control, which play a vital role in the heart's response to various drugs. The autonomic nervous system, comprising the sympathetic and parasympathetic branches, regulates heart rate. Sympathetic activation increases heart rate, while parasympathetic activation...
