Why Use Stents When They Don’t Work?

Again and again, studies have shown that doctors tend to make clinical decisions for patients based on how much they themselves will get paid.In 2007, we learned from the COURAGE trial that angioplasty and stents—percutaneous coronary intervention (PCI)—don’t reduce the risk of death or heart attack

Do Heart Stents Benefit Angina Chest Pain?

Sham surgery trials prove that procedures like non-emergency stents offer no benefit for angina pain—only risk to millions of patients. Angioplasty and stents—percutaneous coronary intervention (PCI)—for stable, non-emergency coronary artery disease are among “the most common invasive procedures per

Why Aren’t Angioplasty Heart Stents More Effective?
Michael Greger M.D. FACLM on 04/10/2025

Why Aren’t Angioplasty Heart Stents More Effective?

Most heart attacks are caused by nonobstructive plaques that infiltrate the entire coronary artery tree. There is no such thing as “1-vessel disease,” “2-vessel disease,” or “left main disease.” Atherosclerotic plaque is continuous throughout the coronary arteries of heart attack victims. In angiopl

The Effectiveness of Angioplasty and Heart Stent Procedures

There are demonstrably no benefits to the hundreds of thousands of angioplasty and stent procedures performed outside of an emergency setting. They don’t prevent heart attacks, enable you to live longer, or even help with symptoms any more than placebo (sham) surgery. Large national cardiology confe
