Coronary Stent Restenosis in a Patient with Sepsis Caused by Pseudomonas Aeruginosa. Case Report

Abstract

Coronary artery disease is a major global health problem, leading to the accumulation of atheromatous plaque within the tunica intima of the coronary artery, limiting blood perfusion throughout the heart. To restore normal blood flow within the coronary artery, the coronary artery is expanded using a balloon-tipped catheter and a stent is placed. Drug-eluting coronary stents are the most effective option in percutaneous coronary intervention while reducing restenosis. However, the implantation of a stent can cause other complications such as infection and thrombosis. The case of a 51-year-old man is presented, who presents a picture of oppressive chest pain intensity 10/10, radiating to the neck and left scapula, an electrocardiogram with ST-segment depression in V3-V6 is performed, coronary angiography is performed with coronary artery disease of multiple vessels, stent restenosis of the circumflex and anterior descending artery, with chronic total occlusion of the right coronary artery, saccular aneurysm of the anterior descending artery. At 3 weeks he presented fever spikes and new very high-risk angina events due to dynamic electrocardiographic changes in the anterolateral face, for which blood cultures were taken, resulting positive for Pseudomonas aeruginosa. Complications such as stenosis phenomenon and stent thrombosis occur in approximately 2% of cases, while coronary stent infection occurs in less than 0.1% of cases.
