Progress against heart disease has stalled, driving down life expectancy in the U.S. after decades in which each generation lived longer than the one that came before, The Wall Street Journal's Betsy McKay reports (subscription).

Why it matters, per WSJ: Cancer was set to take over as the nation's leading cause of death, and it was expected to do so by 2020. But now, heart disease is an "under-recognized contributor" to the decline in U.S. life expectancy.

Dassault Systemes, a French maker of industrial software and technology, is buying New York-based health data provider Medidata in a deal worth $5.8 billion.

The bottom line: Medidata registered a $52 million profit last year on $636 million of revenue, but Dassault is betting that more pharmaceutical and medical device companies will use Medidata's software to help their products clear clinical trials. More than 1,000 health care companies already use Medidata for clinical trial work.
