The cardiovascular system, also known as the circulatory system, includes the heart and blood vessels. It plays an important role in transporting blood to organs and tissues throughout the body.

Heart attacks remain a leading cause of death and disability worldwide. The permanent loss of heart muscle cells-known as ...

During a severe heart attack many heart muscle cells die and are replaced by scar tissue to stabilize the heart wall.

Meanwhile, tissues in other parts of the body don't get enough oxygen, causing muscle pain that shoots from the chest to the arms, and then to the shoulders, jaw, neck or back.

During a heart attack, heart muscle cells die and are replaced by scar tissue. This delays the electrical conduction in the heart and favours the onset of cardiac arrhythmia. To reduce this ...

Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle. However, treatment with heart progenitor cells could result in ...

Heart repair via neuroimmune crosstalk Date: November 17, 2023 Source: Max Delbrück Center for Molecular Medicine in the Helmholtz Association Summary: Unlike humans, zebrafish can completely ...

In the one patient, a 46-year-old woman with advanced heart failure who was waiting for a transplant, the patch remuscularized her heart tissue. She’d had a heart attack in 2016 and developed ...

Cardiac Conduction System Anatomy There are quite a few cells and nodes in your heart’s conduction system, and each has its own cardiac conduction system function, including: Sinoatrial node: As ...

An interdisciplinary research team from the University of Göttingen and Hannover Medical School (MHH) has detected significant changes in the heart muscle tissue of people who died from Covid-19.

A healthy heart typically pumps out 55-70% of its blood volume. With systolic heart failure, this number drops below 40%, indicating that the heart’s contractions have weakened significantly.

After a heart attack, this process of degradation has to be stopped so that tissues can health better. The protein-like polymer, or PLP, platform is made from a polymer that mimics Nrf2.
