Pressure-Derived Indices in the Left Main Coronary Artery Disease

Pressure-Derived Indices in the Left Main Coronary Artery Disease

Left main coronary artery (LMCA) disease can lead to what’s known as a ‘widowmaker’ heart attack, so-called because of the low odds of survival. But this can be avoided if someone is given a stent to open up the narrowed LMCA, or heart bypass surgery. However, research conducted by the Dr Ozan Demir and published in the journal Circulation: Cardiovascular Interventions reveals how doctors may be missing up to 28 per cent of people with LMCA disease because current clinical guidelines on how to interpret test results may need to be updated. https://www.kcl.ac.uk/news/a-commonly-used-test-could-miss-the-most-dangerous-type-of-heart-disease
