Almost a third of all human deaths in the world are caused by cardiovascular disease (CVD), so encouraging news about breakthrough developments in diagnoses powered by machine-learning is enough to make your heart skip a beat. Traditionally, healthcare providers are sluggish to embrace technology and, in addition, the industry is highly regulated, understandably so as people's lives are at stake. However, the growing evidence that machine-learning should be fully utilised is becoming overwhelming. The meshing of big data and machine-learning enables much speedier and accurate diagnostic processes. It is already proving life-saving in healthcare in general and for those with CVD specifically as related conditions can be identified early, and impending strokes and heart attacks spotted in advance.
