New Test Can Detect 'Broken Heart Syndrome' Like a Heart Attack

Topic: Health

Scientists have created a new test called BioTAK that can identify Takotsubo syndrome, also known as 'broken heart syndrome', with high accuracy. This condition mimics the symptoms of a heart attack but doesn't involve blocked coronary arteries. The test uses blood biomarkers and sex to diagnose the condition.

Takotsubo syndrome is a sudden heart condition that affects mostly postmenopausal women. It can be triggered by intense emotional or physical stress. This condition accounts for about 2% of patients initially thought to have a heart attack, but it's very hard to tell apart from a heart attack in the first stages of evaluation.

People with Takotsubo syndrome can experience chest pain, abnormal electrocardiogram results, and elevated levels of cardiac enzymes. These symptoms are similar to those of a heart attack. However, the key difference is that Takotsubo syndrome doesn't involve blocked coronary arteries.

A team of international researchers has developed a new diagnostic scoring system called BioTAK. This tool combines biological sex with several blood biomarkers linked to different processes in the cardiovascular system. The researchers used artificial intelligence to determine which combination of biomarkers provided the most useful diagnostic information and incorporated those markers into a clinical decision tool.

The BioTAK score was tested on nearly 1,800 patients and identified Takotsubo syndrome with high accuracy. The test correctly classified almost 90% of participants before they underwent cardiac catheterization.

Why It Matters

This new test can help doctors diagnose Takotsubo syndrome more accurately, reducing the number of unnecessary invasive tests. This is especially important in India, where heart disease is a growing concern. Early diagnosis and treatment can save lives and improve patient outcomes.
