Other researchers are developing techniques that use cell phone cameras to measure other aspects of heart health, such as blood pressure.
Researchers from the University of Toronto, Canada, and Hangzhou Normal University in Zhejiang, China, Slight changes in facial blood flow from a selfie video using a smartphone’s front-facing camera.
Another team of Chinese scientists used a smartphone to take four photos—a frontal view, two side views, and one top-down view—to get a picture of heart health. We have developed a deep learning algorithm that can detect other signs.Algorithm seemed to focus Subtle changes especially in cheeks, forehead and noseWrinkles and creases under the skin, fatty deposits, etc. that are difficult to detect with the human eye.
It correctly detected heart disease in 80% of cases, but incorrectly identified risk in 46% of cases. This means that not seeking further professional medical diagnosis may cause unnecessary anxiety to the patient. (Read more about invisible warning signs that predict your health.)
The device could be an “inexpensive, simple and effective” way to identify patients who need further investigation, said a cardiologist at China’s National Cardiovascular Disease Center who was involved in the study. increase.
