概括

亚皮性缩性心肌病 (ApHCM) 患者的预后比非ApHCM患者更好,心脏不良事件较少. 左心室喷射分数 (LVEF) 和年龄是ApHCM长期结果的关键预测因素.

科学领域:

心脏病学心脏病学
遗传学是一个遗传学.
内部医学内部医学

背景情况:

皮性多变性心肌病 (Apical hypertrophic cardiomyopathy,ApHCM) 是一种独特的多变性心肌病 (hypertrophic cardiomyopathy,HCM) 亚型,其自然史和预后尚未完全理解.
描述ApHCM对于准确的诊断和风险分层至关重要.

研究的目的:

确定ApHCM患者的临床特征和长期结果.
在APHCM中确定心脏不良事件的独立预测因子.

主要方法:

一个单一中心的回顾性研究涉及479名HCM患者,分为ApHCM和非ApHCM组.
临床,心电图,心声图和生存数据的比较.
主要结局:住院和随访期间发生的重大心脏不良事件.

主要成果:

与非ApHCM患者 (n=109) 相比,ApHCM患者在诊断时年龄较大,并表现出更多的心电图异常,但与非ApHCM患者 (n=370) 相比,他们的脑内尿素水平较低,左心室喷射率 (LVEF) 更好.
在平均5.59年的随访期间,ApHCM患者发生的重大心脏不良事件显著减少 (11.4%与27.2%相比).
在ApHCM中观察到减少全因死亡和致命的心室心律不整. 在ApHCM中,LVEF和年龄独立地预测了不良结果.

结论:

与其他形式的HCM相比,角性HCM与潜在的更好的长期预后有关.
左心室喷射分数 (LVEF) 和患者年龄是ApHCM中不良结果的显著独立预测因素.

关键词:

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...
