Стандартная терапия включает бета-адреноблокаторы, антикоагулянты, дезагреганты. Описаны два клинических случая успешного внутривенного применения левокарнитина с целью кардиопротекции у пациентов старческого возраста с острыми формами ишемической болезни сердца при многососудистом поражении. Послеоперационный период протекал гладко, отмечалась сглаженность динамики биомаркеров (тропонин I, креатинфосфокиназа, МВ-фракция креатинфосфокиназы), ишемические сдвиги ЭКГ были мало выражены. Ожидаемые результаты применения методики — снижение интраоперационных и послеоперационных осложнений ишемии/реперфузии и повышение эффективности клинических результатов стентирования у пациентов высокого риска.</p></abstract><trans-abstract xml:lang="en"><p>The main causes of postoperative mortality associated with percutaneous coronary interventions involving the coronary artery stent insertion are perioperative myocardial infarction and acute heart failure due to inadequate protection of the myocardium against ischemia/reperfusion. The standard therapy includes beta blockers, anticoagulants, antiplatelet drugs. Two clinical cases of successful use of intravenous levocarnitine for cardioprotection in senile patients with acute forms of coronary heart disease with multivessel lesions are reported. The postoperative period went well, smooth dynamics of biomarker levels (troponin I, creatine phosphokinase, MB fraction of creatine phosphokinase) was observed, and ischemic ECG changes were relatively small. The expected results of the technique application include reduction of intraoperative and postoperative complications of ischemia/reperfusion and the increase in effectiveness of the stent insertion clinical outcomes in high-risk patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ишемическая болезнь сердца</kwd><kwd>острый коронарный синдром</kwd><kwd>острый инфаркт миокарда</kwd><kwd>ишемия/реперфузия</kwd><kwd>чрескожные коронарные  вмешательства</kwd><kwd>левокарнитин</kwd><kwd>внутрикоронарное введение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>coronary heart disease</kwd><kwd>acute coronary syndrome</kwd><kwd>myocardial infarction</kwd><kwd>ischemia/reperfusion</kwd><kwd>percutaneous coronary interventions</kwd><kwd>levocarnitine</kwd><kwd>intracoronary administration</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках Государственного задания 075-01609-23-04 «Адъювантная цитопротекция левокарнитином методом  интракоронарного введения при реваскуляризации у больных с острым и хроническим коронарным синдромом (FUEM-2023-0018).
