A rare case of systemic AL-amyloidosis under the mask of myocardial infarction in the absence of myocardial hypertrophy: case report
Abstract
Systemic amyloidosis is a group of diseases associated with extracellular deposition of fibrillar proteins, resulting in the loss of normal organ structure and function. AL-amyloidosis occurs when amyloid is deposited, consisting of full-length lambda or kappa immunoglobulin light chains, or fragments thereof. This article describes the complexity of timely diagnosis of systemic AL-amyloidosis with a predominant heart lesion in the absence of myocardial hypertrophy on the example of an elderly patient in whom the leading manifestation of the disease was heart failure with a preserved left ventricular ejection fraction.
