Symptoms of<unk>  are a combination of heart failure and amyloid deposition in various other organs. Amyloid deposition in the heart causes restrictive diastolic heart failure that progresses to systolic heart failure.<unk>  manifestations include: * Dyspnea on exertion * Peripheral edema and ascites * Pericardial effusion * Arrhythmias (secondary to disruption of the normal electrical system of the heart) * Atrial arrhythmias (such as atrial fibrillation) * First/second degree heart blocks * Syncope * Elevated neck veins and jugular venous pressure * Myocardial ischemia/Angina (secondary to amyloid deposition in the small arteries of the heart) * Myocardial oxygen demand is increased in patients with<unk> , regardless of changes to coronary perfusion. For patients with light-chain<unk> , there can be depositions of amyloid into numerous different organs. Deposition of amyloid into other organs makes the diagnosis of<unk>  difficult as these extracardiac manifestations mask the diagnosis. Extracardiac manifestations include: * Macroglossia * Periorbital bruising * Loss of the third and fourth heart sound * Thromboembolisms * Symmetric sensory neuropathy (such as bilateral carpal tunnel) * Postural hypotension (secondary to autonomic neuropathy) * Nephrotic syndrome (secondary to free light chain damage to the kidneys/deposition of amyloid in the kidneys)
