低钙较少见,但却可引起充血性心衰。许多临床医生可能尚未认识低钙和心衰的关系,它常被忽略,或仅见于内科学、心脏病学、内分泌学教科书中。曾有几篇关于低钙诱发心肌病的报道,但这些病例大都有其他影响心肌收缩的并发病。虽然一些学者曾推测低钙可能促成充血性心衰,但他们并未对患者的左室功能进行定量研究。 Low calcium is rare, but it can cause congestive heart failure. Many clinicians may not yet know the relationship between hypocalcemia and heart failure, it is often overlooked, or only found in medical, cardiology, endocrinology textbooks. There have been several reports of hypocalcemic cardiomyopathy, but most of these cases have other complications that affect myocardial contractions. Although some scholars have speculated that hypocalcemia may contribute to congestive heart failure, they did not conduct quantitative studies of patients’ left ventricular function.
