Postoperative Risks Posed by Coronary Stents Explored in AHRQ Study
Patients who have surgery to receive coronary stents have an approximately 2 percent risk of heart attack within one year of the surgery, but no difference in mortality is shown between those patients and matched surgery patients who did not receive stents, according to an AHRQ-funded study. Researchers used data for patients with coronary stents implanted in a Veterans Affairs hospital from 2000 to 2010. Each patient with a stent was matched with two surgical patients without stents on surgical characteristics and cardiac risk factors. Adverse cardiac events followed surgery in 5.7 percent of the 9,391 patients with stents and 3.6 percent of the 18,782 patients without stents. The trends for two years after stent placement revealed that the incremental risk for heart attack decreased from 5 percent immediately after stent placement to 2 percent one year later, and then was no longer significantly elevated. The incremental risk did not vary by stent type. “The Incremental Risk of Coronary Stents on Postoperative Adverse Events” appeared online with an abstract April 17 in the journalAnnals of Surgery.
