Abstract :effects of endotracheal intubation and laryngeal mask airway insert ignore into journalissuearticles values(LMA); insertion on the risk of myocardial ischemia in patients with coronary artery disease insert ignore into journalissuearticles values(CAD); and/or congestive heart failure insert ignore into journalissuearticles values(CHF);. Methods: Thirty patients, ASA lll-IV, having CAD and/or CHF, undergoing elective peripheral surgery insert ignore into journalissuearticles values(orthopaedic, urologic, ear-nose and throat and ophthalmologic surgery); were investigated. Anesthesia was induced with 0.2 mg/kg etomidate, 15pg/kg alfentanil and 0.1 mg/kg vecuronium i.v. in all patients. In group I the patients were intubated, in group II LMA was inserted for maintenance of airway. Mean arterial pressure insert ignore into journalissuearticles values(MAP);, heart rate insert ignore into journalissuearticles values(HR);, rate pressure product insert ignore into journalissuearticles values(RPP);, and ST segmet changes were recorded. Postoperatively 12 lead electrocardiography and CPK, CPK-MB levels were also recorded. Results: MAP and RPP increased significantly 1 min after intubation in group I, there was no difference in MAP and RPP and a significant decrease in HR in group II. ST segment changes indicated ischemia were recorded 15 times in 6 patients in group I and 4 times in 3 patients in group II. Conclusion: Unless contraindicated, airway maintenance by LMA should be preferred in patients with CAD in order to protect myocardial perfusion.
