Cardiac amyloidosis is a subcategory of amyloidosis where there is depositing of the protein amyloid in the cardiac muscle and surrounding tissues. Amyloid, a misfolded and insoluble protein, can become a deposit in the heart's atria, valves, or ventricles .
Amyloid cardiomyopathy (stiff heart syndrome) [5] is a condition resulting in the death of part of the myocardium (heart muscle). It is associated with the systemic production and release of many amyloidogenic proteins , especially immunoglobulin light chain or transthyretin (TTR). [ 6 ]
Due to this resistance to degradation, when amyloid fibrils accumulate in the heart's walls, specifically the left ventricle, rigidity prevents the heart from properly relaxing and refilling with blood: this is called diastolic dysfunction which can ultimately lead to heart failure. [2]
Amyloid shows up as homogeneous pink material in lamina propria and around blood vessels. 20× magnification. Amyloids are aggregates of proteins characterised by a fibrillar morphology of typically 7–13 nm in diameter , a β-sheet secondary structure (known as cross-β) and ability to be stained by particular dyes, such as Congo red .

Amyloid deposits in tissue can cause enlargement of structures. Twenty percent of people with AL amyloidosis have an enlarged tongue, that can lead to obstructive sleep apnea, difficulty swallowing, and altered taste. [11] Tongue enlargement does not occur in ATTR or AA amyloidosis. [10] Deposition of amyloid in the throat can cause hoarseness ...
Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80."
AA amyloidosis is a form of amyloidosis, a disease characterized by the abnormal deposition of fibers of insoluble protein in the extracellular space of various tissues and organs. In AA amyloidosis, the deposited protein is serum amyloid A protein (SAA), an acute-phase protein which is normally soluble and whose plasma concentration is highest ...
The C-reactive protein is produced by the liver, and may mean that there is inflammation in the body when levels increase, according to the Mayo Clinic. Refined carbohydrates
