Google Predicts Heart Attacks Through Eyes

By looking at the human eye, Google’s algorithms were able to predict whether someone had high blood pressure or was at risk of a heart attack or stroke, Google researchers said last week, opening a new opportunity for artificial intelligence in the vast and lucrative global health industry.

The algorithms didn’t outperform existing medical approaches such as blood tests, according to a study of the finding published in the journal Nature Biomedical Engineering. The work needs to be validated and repeated on more people before it gains broader acceptance, several outside physicians said.

But the new approach could build on doctors’ current abilities by providing a tool that people could one day use to quickly and easily screen themselves for health risks that can contribute to heart disease, the leading cause of death worldwide.

The Harms from Cigarette Smoking

A large study from the BMJ indicates that smokers must quit cigarettes, rather than simply cut back on them, to significantly lower their risk of heart disease and stroke.

Statistics demonstrated that those who smoked even one cigarette each day were still about 50% more likely to develop CVD, and 30% more likely to have a stroke, than people who had never smoked.

Cardiovascular disease, not cancer, is the greatest mortality risk for smoking, causing about 48% of smoking-related premature deaths. While the percentage of adults in the UK who smoked had been falling, the proportion of people who smoked one to five cigarettes a day had been rising steadily, researchers said.
