The coronavirus can damage the heart, according to a major new study which found abnormalities in the heart function of more than half of patients. The coronavirus can damage the heart, according ...
The M protein is a transmembrane protein with three transmembrane domains and is around 230 amino acid residues long. [8] [9] In SARS-CoV-2, the causative agent of COVID-19, the M protein is 222 residues long. [10] Its membrane topology orients the C-terminus toward the cytosolic face of the membrane and thus into the interior of the virion.
Inflammation of the heart muscle, or myocarditis, seems to stem from the novel coronavirus attacking the heart, or the inflammation caused by the immune system overreacting to the virus ...

Figure A shows the location of the heart and a normal heart and pericardium (the sac surrounding the heart). The inset image is an enlarged cross-section of the pericardium that shows its two layers of tissue and the fluid between the layers. Figure B shows the heart with pericarditis.
On chest X–ray, the heart looks posteriorly rotated. Another feature is the sharp delineation of pulmonary artery and transverse aorta due to lung deposition between these two structures. If there is partial absence of pericardium, there will be bulge of the left atrial appendage. On CT and MRI scans, similar findings as chest X–ray can be ...
The morphology of the SARS-related coronavirus is characteristic of the coronavirus family as a whole. The viruses are large pleomorphic spherical particles with bulbous surface projections that form a corona around the particles in electron micrographs. [50] The size of the virus particles is in the 80–90 nm range.
Thromboembolic events, such as blood clots show with high risk in COVID-19 patients in some studies. [42] Other cardiovascular complications may include heart failure, arrhythmias, and heart inflammation. [43] [44] [45] They are common traits in severe COVID-19 patients due to the relation with the respiratory system. [46]
