The progression from concentric left ventricular (LV) hypertrophy to heart failure has not been well defined. Of 159 predominantly hypertensive African-American patients with LV hypertrophy and a normal ejection fraction (EF), 28 (18%) developed a reduced EF after a median follow-up of approximately 4 years. Risk factors for this outcome included a history of coronary artery disease, pulmonary edema seen on a chest x-ray, or a subsequent myocardial infarction.
从同心性左心室肥厚发展至心力衰竭的过程尚未完全明确。在159例主要为高血压的非裔美国左心室肥厚患者中，其射血分数（EF）正常，经过约4年的中位随访后，28例（18%）出现了EF降低。这一结果的危险因素包括冠状动脉疾病史、胸部X线显示的肺水肿或随后发生的心肌梗死。
