Angioplasty not always worth it, findings show

The findings showed angioplasty improved angina-related symptoms in some patients but at a cost generally considered to be prohibitive as a routine treatment.

But researchers say this doesn't mean the procedure shouldn't be performed. They say there needs to be a way to fix the cost.

Previous research has shown that angioplasty combined with other medical therapy does not reduce the incidence of cardiovascular events any more than medication alone.
