Key indicator of heart diseases

A team that includes Dartmouth College researchers has discovered a new way to detect cardiolipin, a key indicator of heart diseases and some genetic disorders.

The results, which appear in the journal Analytical Chemistry, may eventually help to diagnose these conditions earlier on and to provide real-time monitoring of cardiolipin levels.

Cardiolipin is a unique lipid of mitochondria, the cell structures that generate energy. Cardiolipin is important for mitochondrial function in both respiration and apoptosis (programmed cell death). This lipid is an important indicator for cardiac diseases, Barth syndrome and Tangier disease and has been linked to neurodegenerative diseases, HIV and cancers.
