Angioplasty’s golden era may be fading

Recent analyses suggest the meteoric rise of angioplasty during the past three decades has ended. Three major studies indicate that using the procedure to open blocked arteries to treat chest pain, or angina, may be riskier and no more beneficial than medication. The research also suggests angioplasty is used too often, and in many cases, the modest benefits don't justify the procedure's cost.
