Clinical, echocardiographic, and EKG clues to cardiac amyloidosis.17,19,20,26,27,28,29,30,31,32 AL: amyloid light chain; BB: beta blocker; ACEi: angiotensin converting enzyme inhibitor; ARB: angiotensin receptor blocker; ARNI: angiotensin receptor neprilysin inhibitor; LVEF: left ventricular ejection fraction; GLS: global longitudinal strain; EKG: electrocardiogram; LV: left ventricle; MI: myocardial infarction. Here, ACE is linked to cardiac amyloidosis.
