Big data and data sharing: opportunities for the urgent challenges in cardiovascular disease

The past half-century has witnessed unbelievable progress in cardiovascular (CV) medicine, determining a swirling reduction in mortality. Despite this progress, the decline in incidence and mortality leveled off in recent years. Age-adjusted CV mortality remained flat independently of race and ethnicity, with only few exceptions. In other words, disparity in CV health is still observed across sex, race and ethnicity. The rise of obesity, diabetes and other risk factors has been widely used to explain this trend in CV mortality.
