New research led by Patricia Thistlethwaite, MD, cardiothoracic surgeon at UC San Diego Health, shows that a simple blood test could help doctors detect serious heart problems earlier, including pulmonary arterial hypertension, potentially before they become life-threatening.
"This has been a holy grail in the field — a simple blood biomarker that could tell us you have the disease, and yes, it's getting worse," said Thistlethwaite. "(It) would be a great advance compared to the multiple combinations of tests, some of them invasive, that are used to diagnose this disease."
