A new study in the Journal of the American Medical Association found that an inexpensive blood test could predict future heart problems.
The blood test detects levels of a protein in the blood called NT-proBNP. NT-proBNP levels show that a heart is under stress at early stages, when other types of tests like an electrocardiogram and stress test might miss signs of trouble.
This blood test could help doctors to identify patients at highest risk earlier.
The researchers studied about 1,000 patients for more than three years and found that those with the highest levels of the amino acids had about eight times the risk of heart attack, heart failure or stroke.
