A bold new approach to heart attack treatment is challenging conventional wisdom. Cardiologists are now suggesting a wait-and-see strategy for additional stents, a controversial move that could revolutionize care.
When a patient experiences an acute heart attack due to a blocked coronary artery, the immediate response is to open the artery with a stent procedure. But here's where it gets controversial: if other arteries show signs of narrowing, the traditional approach has been to treat them all at once. However, a recent study by cardiologists at Radboud university medical center suggests a different path.
The study, published in The New England Journal of Medicine, involved 1,146 participants and found that waiting to treat those additional narrowed arteries is just as safe as immediate treatment. And this is the part most people miss: by waiting, the number of stent procedures can be halved.
Each year, thousands of people are admitted to hospitals with heart attacks. The urgency to open the blocked artery is critical to prevent heart muscle damage. But during these procedures, doctors often discover other narrowed arteries. The question then becomes: should they treat them all immediately, or can they wait for a calmer moment?
Researchers from 41 hospitals, led by Radboudumc, set out to answer this question. Their study found that waiting is not only safe but also reduces the need for immediate, extensive treatment. Professor Robin Nijveldt, a cardiovascular imaging expert at Radboudumc, explains the key finding: "We saw no difference in outcomes between the two groups. Death, new heart attacks, and hospital admissions due to heart failure were the same, regardless of whether treatment was immediate or deferred."
Professor Niels van Royen, a cardiologist, sheds light on why this approach works. "In the acute phase, we measure pressure inside the blood vessel to determine if stenting is necessary. Later, we can use an MRI scan to map the heart's blood flow. If the heart is receiving adequate oxygen, stenting a single narrowed artery may not be essential."
But why not just treat everything at once? Van Royen notes that while it's often more convenient for patients, there are situations where waiting is necessary. "Sometimes, the patient's condition or the arrival of another critical case may delay additional treatment. Now we know it's safe to do so."
The study also highlights the role of MRI scans in reassuring patients. "An MRI scan a few weeks later can confirm that no further stenting is needed. However, some patients choose to skip follow-ups, which may not be the best decision," Van Royen adds.
This new approach is expected to challenge current guidelines, which recommend immediate treatment of all narrowed arteries during the acute phase. "Our study provides clarity that the immediate treatment benefit is short-lived and not seen in the long term," Nijveldt concludes.
