Cardiac Amyloidosis or Stiff Heart Syndrome is caused by deposits of abnormal proteins in the heart tissue. This results in the heart ceasing to function properly due to the replacement of normal heart muscle tissue with amyloids. Cardiac Amyloidosis is associated with thick heart walls and large atria. It can affect electrical conductivity resulting in arrhythmias and heart block .1 2 3

Top panel = light microscopy; bottom panel = polarised light microscopy. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6334035/.

Although Cardiac Amyloidosis can be inherited, it can also develop from bone marrow (AL – amyloid light chain) or liver (ATTR – amyloid transthyretin) sources. It is more common in men and rare in people under age 40.

A 29-year-old man with no medical history or coronavirus disease 2019 (COVID-19) infection developed chest pain 4 days after his first dose of the Moderna mRNA COVID-19 vaccine (Moderna, MA, USA).

Inflammation of the myocardium (myocarditis) is highly-associated (temporally) with the COVID-19 injectable products.4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

The figures below are heart tissue specimens stained with Hematoxylin–eosin (H&E) stain which is a stain used for visualizing Eosinophylic amyloid.

Figure 3: Histopathological Findings from Endomyocardial Biopsy and Autopsy. Hematoxylin–eosin stains of heart-tissue specimens obtained by means of endomyocardial biopsy in patient 1 (Panel A) and autopsy in patient 2 (Panel B) showed myocarditis in both patients, with multifocal cardiomyocyte damage (arrows) associated with mixed inflammatory infiltration. Scattered eosinophils were noted (arrowheads). The images of the hematoxylin–eosin stains were obtained with 10× eyepieces and 40× or 60× objectives. Additional information is provided in the Supplementary Appendix. RV denotes right ventricle, and LV left ventricle. https://pubmed.ncbi.nlm.nih.gov/34407340/

Figure 4: Histopathology of the heart. (A) Hematoxylin and eosin stains of atrial septum shows massive inflammatory infiltration with neutrophil predominance. (B) The myocytes often show contraction band necrosis (yellow arrows), which were highlighted by Masson’s trichrome staining. (C) The atrioventricular node area shows extension of atrial myocarditis to the superficial layer of the node. (D) The ventricular myocardium is free of inflammatory infiltrates, but there are multiple large foci of contraction band necrosis (yellow arrows) particularly in the left ventricular wall and the ventricular septum. Bars represent 100 µm. The blue arrows in insets show where the section was taken from the low magnification views. Hematoxylin and eosin stain was used for the specimen shown in (A) and Masson’s trichrome stain was used for the specimen shown in (B-D). RA = right atrium, LA = left atrium, RV = right ventricle, LV = left ventricle. https://pubmed.ncbi.nlm.nih.gov/34664804/

Figure 6: The superior sagittal sinus has been partially incised showing acute, venous thrombosis (arrows). H&E sections show centrally located red blood cells/hemorrhagic areas and surrounding fibrin accumulations (B, Orig. Magn. 10 ×) as well as small areas with alternating lines of erythrocytes and fibrin (C, Orig. Magn. 40 ×). https://pubmed.ncbi.nlm.nih.gov/34591186/

Cardiac amyloidosis, also called infiltrating interstitial fibrosis, involves deposition of amyloid in the myocardium. In contrast to traditional myocardial fibrosis, the condition arises independently of cardiac stress or load. In cardiac amyloidosis, ECG and imaging may yield findings that resemble myocardial fibrosis (low voltage, hypertrophy and signs of fibrosis). Various biomarkers and cardiac MRI can distinguish between the conditions. Cardiac amyloidosis causes severe heart failure with a poor prognosis.25

In a study entitled: “Myocarditis is rare in COVID-19 autopsies: cardiovascular findings across 277 postmortem examinations”, 11 cases of Cardiac Amyloidosis were identified in contrast to only 20 cases of myocarditis.

Amyloidosis, albeit not the result of COVID-19, was a more homogeneous finding, being reported in 5 separate studies with the highest incidence in any study being 28.5% (6 of 21 cases). [Halushka MK. et al., 2021]
