Mory Gharib and Caltech colleagues have developed an app which uses a phone camera to monitor heart health. When held to the neck, it infers the left ventricular ejection fraction of the heart by measuring the amount that the carotid artery displaces the skin of the neck as blood pumps through it.
According to Gharib:”What is exciting about this study is that it shows our technique is as accurate as echocardiography at estimating LVEF when both are compared to the gold standard of cardiac MRI. This has the potential to revolutionise how doctors and patients can screen for and monitor heart disease both in the US and the developing world.”
