Surgery for Blocked Arteries Is Often Unnecessary, Says StudyWibbitz - News
Surgery for Blocked Arteries Is Often Unnecessary, Says Study. The study known as Ischemia followed 5,179 participants for a median time span of three and a half years. It is the largest study of its kind. The federal study focused on patients who were treated for non-emergency blocked arteries with stint or bypass surgeries and patients who were treated with medication alone. The study found that deaths occurring after stint or bypass surgery reached 145 people. Deaths among those who were treated with only medication reached 144. 276 of those in the stint and bypass group suffered heart attacks compared to 314 of those who were treated with medication. Many doctors expected that stents or bypass would benefit those with severe chest pain or blockages. But according to the study, "there was no suggestion that any subgroup benefited.". Doctors say the study "certainly will challenge our clinical thinking."
