Cardiac clinical manifestations of amyloidosis
| Clinical characteristics of cardiac amyloid involvement |
|---|
| Dilated cardiomyopathy (cardiomegaly, predominant systolic dysfunction) |
| Restrictive cardiomyopathy (slight cardiomegaly, predominant diastolic dysfunction, stiff heart syndrome) |
| Congestive heart failure |
| Electrocardiographic disorders (rhythm abnormalities, low voltage QRS complex, sick sinus syndrome, pseudoinfarct pattern, atrioventricular and ventricular conduction abnormalities) |
| Coronary insufficiency (myocardial infarction, angina pectoris) |
| Valvular dysfunction |
| Pericardial tamponade |
| Enhanced sensitivity to digitalis glycosides |
| Atrial thrombosis—embolisation |
