Just recently, researchers found that risks associated with non-cardiac surgeries are highest in the first six months following a coronary stent implantation. Undergoing a surgery post-stent implantation just might not be a good idea.
Stents and Non-Cardiac Procedures
Researchers performed a retrospective analysis to find out the incremental risk of non-cardiac procedures on patients that recently underwent stent implantation. That is, they wanted to find what risks are present if you recently had a stent implanted in you and you’re planning to undergo a non-cardiac surgery.
The analysis included 20,590 patients undergoing non-cardiac surgery within two years of getting a stent, and 41,180 patients with stent but did not undergo non-cardiac surgery in the two years following the implantation.
The results of the study, published in the Journal of the American College of Cardiology, suggest that in the first month following a non-cardiac surgery, patients who received a stent in the previous 24 months were at higher risk of being diagnosed with myocardial infarction(MI) and/or need coronary revascularization.
Recovering Completely Before Another Surgery
This just highlights the need for ample recovery time before undergoing other medical or surgical procedures. When undergoing controlled stent placement, you will likely need a few weeks to let the body recover properly. The stent’s mesh will be covered by arterial cells, creating an inner layer resembling the inside of a normal blood vessel, but it will take some time.
The study suggests delaying any non-cardiac procedure in the first six months following a stent implantation.
“The incremental risk of non-cardiac surgery on adverse cardiac events among post-stent patients is highest in the initial six months following stent implantation and stabilizes at 1.0 percent after six months,” the authors said.
Patients undergoing elective, high-risk, or inpatient surgeries, and those with drug-eluting stents may benefit most from a 6-month delay after stent placement, the study concludes.
