Biomarker to tackle cardiovascular risk in older people?

Biomarker to tackle cardiovascular risk in older people?
25th May 2011

Older patients, possible home care users, who have symptoms of heart failure and a certain biomarker in the blood have an associated increased risk of death, according to new findings.

A study published in journal JAMA found that increased concentrations in the blood of biomarker copeptin or a combination of high levels of copeptin concentrations and biomarker NT-proBNP, along with symptoms of heart failure, caused an increased risk of all-cause death.

Copeptin could be a potential surrogate marker for measurement of vasopressin - a cardiovascular disease marker - in the blood.

According to authors: "These data, together with our findings of the prognostic information provided by measurement of copeptin concentrations in elderly patients with symptoms of heart failure, suggest that vasopressin may be a potential target for therapeutic intervention."

This follows Johns Hopkins research which revealed that when a stroke occurs, a 'survival protein' is produced in the brain in order to protect cells.
