Biomarker to tackle cardiovascular risk in older people?

A biomarker for cardiovascular conditions has identified a possible therapeutic target for heart failure.
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
