San Francisco, Feb 20 (Ians) A group of scientists has discovered that in addition to the lungs and respiratory system, Covid-19 may have long-term effects on heart health, even in patients with no history of heart disease.
According to Time, Dr Andrew Marks, chair of the US-based Columbia University’s Department of Physiology, and his colleagues documented abnormalities in the heart tissue of Covid-19 patients who died as a result of the disease.
The team performed autopsies and discovered a number of anomalies, particularly in the way heart cells regulate calcium.
Calcium is required for all muscles, including those in the heart, to contract. Muscle cells store calcium and use special channels within their cells to release it when it is needed, according to the report.
In some cases, such as heart failure, the channel remains open in an attempt to assist the heart muscle in contracting more actively.

New York, Feb 19 (Ians) Scientists have found that Covid-19 infection can cause changes in calcium channels that can affect how the heart beats which can also trigger inflammation and oxidative stress in the heart.
In heart tissue from patients who had Covid-19, the team from Columbia University observed increases in oxidative stress (harmful production of unstable molecules) and signals of inflammation, as well as changes in calcium.
They also detected adverse changes to a protein called RyR2, which is responsible for regulating the heart’s calcium ion levels.
The heart muscle, like all muscle cells, needs calcium ions to contract.
The heart’s system for managing calcium ions is essential for the coordinated contractions of the atria and ventricles that pump blood throughout the body.
When calcium in the heart becomes dysregulated, it can cause arrhythmias or heart failure.

Exclusive: Following in the footsteps of fellow ballers like Kobe Bryant (Kobe Studios), Lebron James (SpringHill Entertainment), and Stephen Curry (Unanimous Media), NBA All-Star and Dwight Howard is getting into the film business. The Washington Wizards center, via Mansa Productions, has come aboard as an executive producer of Percy, an anti-gmo indie film starring Oscar-winner Christopher Walken, Christina Ricci, and Zach Braff.
Grasshopper + Marks Productions (Brewmaster) has also signed on as exec producers of the film, which is being directed by Clark Johnson.
Written by Hilary Pryor and Garfield L. Miller, the plot follows a small-town Saskatchewan farmer Percy Schmeiser (Walken) who challenges a major conglomerate when the company’s genetically modified (Gmo) canola is discovered in the 70-year-old farmer’s crop.
Additional cast includes Roberta Maxwell as Percy’s wife; Adam Beach as Percy’s neighbor, Alton Kelly; Luke Kirby as Percy’s son; Martin Donovan as the conglomerate’s lead lawyer,...
