Similar to the other subtypes of cardiac amyloidosis, a biopsy is required for diagnosis. However, formal diagnosis of Senile cardiac amyloidosis is a diagnosis of exclusion. Biopsy with histological evaluation can rule out Light chain and Familial subtypes, leaving the diagnosis of Senile. This type is often misdiagnosed, however, greater use of cardiac magnetic resonance has increased the rate of diagnosis The severity of the disease tends to be less than the Light chain and Familial variants. This is due to the amount of time that it takes to accumulate the amyloid depositions being longer in the Senile variant. Symptoms and signs
Symptoms of cardiac amyloidosis 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.Cardiac 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 cardiac amyloidosis, regardless of changes to coronary perfusion.For patients with light-chain amyloidosis, there can be depositions of amyloid into numerous different organs. Deposition of amyloid into other organs makes the diagnosis of cardiac amyloidosis difficult as these extracardiac manifestations mask the diagnosis.
Dental abscess—A dental abscess is a collection of pus that accumulates in teeth or gums as a result of bacterial infection, giving rise to a severe throbbing pain at the site of the abscess. It is caused by consuming sugary or starchy food and poor dental hygiene and is treated by a dentist by draining the pus and, possibly, removing the infected tooth/teeth altogether. See also
