An abnormal blood pressure response to exercise has been reported to be associated with left ventricular subendocardial ischemia in patients with hypertrophic cardiomyopathy (HCM), but the underlying mechanism remains unclear. We report a case of HCM with an abnormal blood pressure response and subendocardial ischemia, in which the analysis of heart rate variability revealed exercise-induced vagal enhancement. The present case highlights the possible mechanism linking abnormal blood pressure response and left ventricular subendocardial ischemia in patients with HCM.
据报道,肥厚型心肌病(HCM)患者运动时血压异常反应与左心室心内膜下缺血有关,但其潜在机制尚不清楚。我们报告了一例伴有血压异常反应和心内膜下缺血的HCM病例,其中心率变异性分析显示运动诱发迷走神经增强。本病例突出了HCM患者血压异常反应与左心室心内膜下缺血之间可能的机制。
