For people with Type 2 diabetes and stable heart disease, drug treatments are as effective as angioplasty or bypass surgery in some cases, a new study suggests. It's an important issue given that adults with Type 2 diabetes are two to four times more likely to develop heart disease, and heart attacks and strokes are more likely to be fatal, the researchers said. When doctors decide angioplasty and a stent (a wire mesh scaffold that props open an artery) are needed to restore blood flow and reduce chest pain, the latest results suggest it's safe to use drug treatments. But for people with extensive coronary artery disease, getting invasive bypass surgery right away may help to prevent a future heart attack.
