Diseased hearts may be thrown out of rhythm by structural differences -- now visible for the first time -- in protein groups that connect heart muscle cells, according to the authors of a study to be ...

"The human heart actually has multiple layers of helically aligned muscles with different angles of alignment," said Huibin Chang, a postdoctoral fellow at SEAS and co-first author of the paper. "With ...

What makes a body’s organs into what they are is more than just a grouping of specialized cells. They also need to be oriented and attached to each other and scaffolding in order to create structures ...

Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying donated human hearts found that diabetes disrupts how heart cells produce ...

The cardiac troponin test detects damage to the heart muscle. Troponin is a protein that appears in the blood only when the heart muscle is damaged, as in a heart attack. There are other causes of ...

Phase II ARCHER trial showed a significant reduction in left ventricular (LV) mass (p=0.0117) and improvements in multiple key cardiac MRI (CMR) measures of structural heart recovery in patients with ...

Uncontrolled high blood pressure & blood sugar can alter structure of heart muscle, obstructing the heart's electrical ...
