In the US and Europe, 500,000 patients have stents for stable chest pain, and there were a lot of questions about whether the devices actually alleviate pain. A new study suggests they don’t.
Stents are commonly used for stable chest pain - but the devices may not be helping.
There's an epidemic of unnecessary medical treatments, as David Epstein of ProPublica recently documented in a terrific investigation: Doctors routinely perform procedures that aren't based on high-quality research, or even in spite of evidence that contradicts their use.
One of the prime examples of a dubious treatment that Epstein and others have pointed to is cardiologists putting little mesh tubes called stents in patients with stable angina - chest pain caused by clogged coronary arteries that arises only with physical exertion or emotional stress.
Doctors insert the devices into narrowed or blocked arteries to pop them open, helping blood flow to the heart again. The idea is that stents should help soothe the suffering of patients with angina (or chest pain) and drive down the risk of a heart attack and death in the future.
