Elevated Biomarkers Persist in Heart Attack Patients After Discharge
A biomarker is a protein measured in the blood whose concentration can indicate the presence or severity of disease.
In the study, researchers examined a subset of patients in a 4,500-patient heart attack registry from 24 U.S. hospitals.
They found that 9 percent of these participants had elevated levels of the biomarker troponin (TnT) after six months.
Thirty three percent had elevated level of the biomarker N-terminal pro-B-type Natriuretic Peptide (NTBNP) after six months.
Both TnT and NTBNP are associated with shortness of breath; NTBNP is associated with angina.
"These elevated biomarkers are definitely associated with a reduced quality of life for patients and may signal even worse outcomes," said Dr. David Lanfear.
"This data raises two important issues. The first is whether the biomarkers are a sign of ongoing problems or a reflection of the past heart attack itself. The second is whether closer monitoring of patients post heart attack, can help target our treatment to those who need it most," he added.
