Health industry expects little change from heart study

A new federal study said stents and bypass surgery are no more effective than drugs for treating blocked arteries, but the health care industry and its investors aren't banking on major changes to heart care as a result.

The big picture: Placing stents and performing bypasses are two of the most common operating room procedures. Science continues to say we don't need to be doing them so often, but overhauling that standard of care isn't easy — in part because hospitals and device makers make a lot of money from them.

More older Americans rely on Medicare and Medicaid

Retirement in America is growing less secure, physically and financially, given the omnipresent threat and cost of serious illness or disease.

Why it matters: Qualifying for Medicare does not guarantee that older adults will skirt potentially ruinous medical bills. Millions of seniors have also come to rely on the taxpayer-funded program for lower income people — Medicaid — and there's no indication that will slow down.
