Minimally invasive myocardial revascularization in acute period of myocardial infarction after complicated right coronary artery stenting

Multi-vessel coronary artery disease is quite a common state, which is often diagnosed by coronary angiography in patients with both stable coronary artery disease and acute coronary syndromes. Major difficulties in percutaneous coronary intervention include stent thrombosis and the need for antiplatelet therapy (aspirin and a P2Y12 inhibitor). Stent thrombosis leads to the recurrence of myocardial infarction and may occur within the first few hours after percutaneous coronary intervention. The use of dual antiplatelet therapy, especially that combined with low-molecular-weight heparin in the first days after myocardial infarction, poses a risk of bleeding, which often occurs in real clinical practice. Among P2Y12 inhibitors, ticagrelor causes bleeding somewhat more frequently than clopidogrel. A case of multi-vessel coronary artery disease is described in this paper. Coronary angiography revealed right-dominant circulation; occlusion of the proximal and medial segments of the right coronary artery, thrombolysis in myocardial infarction flow grade 0; stenosis of the left main coronary artery (50-60%), thrombolysis in myocardial infarction flow grade 2; diffuse stenosis of the medial and distal segments of the left anterior descending artery, thrombolysis in myocardial infarction flow grade 1; stenosis of the proximal segment of the left circumflex artery (> 75%), thrombolysis in myocardial infarction flow grade 1. The patient underwent percutaneous coronary intervention; the stents were implanted in the infarct-dependent right coronary artery. The clinical course was complicated by early stent thrombosis with subsequent thrombus extraction; a day later melena developed. Bleeding was stopped, the intensity of antithrombotic therapy was reduced: the combination of aspirin and ticagrelor was replaced by the combination of aspirin and clopidogrel. Six weeks after stenting of the infarct-dependent coronary artery, complete myocardial revascularization (hybrid intervention) was performed: coronary artery bypass grafting [the left internal mammary artery → the left anterior descending artery], coronary autogenous bypass grafting [the aorta → the right coronary artery and the aorta → the left circumflex artery]. The role of fractional flow reserve or instantaneous wave-free ratio-controlled complete myocardial revascularization techniques is discussed. The following algorithm for myocardial revascularization was used: percutaneous coronary intervention for the right coronary artery + coronary artery bypass grafting-3: the left internal mammary artery → the left anterior descending artery, the aorta → the left circumflex artery, the aorta → the right coronary artery.

The aim of the paper is to correlate the results of endovascular myocardial revascularization (EMR) in patients under 40 years of age with acute coronary syndrome (ACS) / stable angina, primary EMR age ≤35/36–40 and stent diameter. Materials and Methods. The authors examined 208 patients (24–40 years of age) with coronary artery disease: 157 patients (75.5 %) aged 36–40; 51 patients (24.5 %) aged ≤35. All in all, 165 (79.3 %) patients underwent EMR; 32 patients (15.4 %) underwent coronary artery bypass grafting; 11 patients (5.3 %) refused medical intervention. EMR results and the quality of life were studied in 126 patients (76.4 %) at 10–107 months of observation (62.5±2.6 months). Results. 84 patients with ACS (50.9 %) and 81 patients with stable angina (49.1 %) underwent EMR. There were no any peri-procedural complications. The authors observed 0 % hospital and 30-day mortality. The survival rate of patients for the period up to 9 years was 99.2 %; long-term mortality was 0.8 %; the constancy of results up to 1, 2 and 3 years of follow-up was 90.5 %, 84.1 % and 81.7 %, respectively, and up to 5–9 years it was 79.4 %. An active lifestyle was verified in 74.6 % of patients; a sparing lifestyle was observed in 25.4 %; 86.5 %, of patients returned to work; transient sexual disorders were found in 28.6% of patients. 83.3 % and 27.8 % of patients kept to drug therapy and dietary regimen. 34.1 % and 23.8 % of patients kept smoking and taking power drinks; overweight and obesity were observed in 23.8 % and 19 % of patients. Recurrent myocardial infarction (MI) / angina was verified in 23 % of patients; 20.6 % of patients underwent second EMR. 23 % of patients got depressed due to recurrent myocardial infarction / angina, while 18.3 % of patients were down due to the quarantine (COVID-19); 6.3 % suffered from panic attacks, for fear of recurrent anginous pain. Conclusion. Predictors of recurrent EMR and stability of results were: 1) ACS; 2) patients’ age (≤35); 3) history of MI, ejection fraction ≤35–40 %, diabetes; 4) stent diameter (<28 mm); 5) smoking and taking power drinks. The leading predictor was the aggressiveness of atherosclerosis and diabetes in persons under 40, causing: a) early stent dysfunction; b) native and “protected” coronary vessels damage in case of intact stents patency.

Корреляция результатов эндоваскулярных реваскуляризаций миокарда (ЭВРМ) у больных моложе 40 лет с острым коронарным синдромом (ОКС) / стабильной стенокардией, возрастом при первичной ЭВРМ ≤35 лет / 36–40 лет и диаметром стентов. Материалы и методы. Обследовано 208 больных ИБС в возрасте 24–40 лет: 157 (75,5 %) чел. – в возрасте 36–40 лет, 51 (24,5 %) – ≤35 лет. ЭВРМ выполнена 165 (79,3 %) больным, коронарное шунтирование – 32 (15,4 %), 11 (5,3 %) пациентов отказались от вмешательства. Исходы ЭВРМ и качество жизни изучены у 126 (76,4 %) больных на сроках 10–107 мес. (62,5±2,6 мес.) наблюдения. Результаты. ЭВРМ выполнена 84 (50,9 %) больным ОКС и 81 (49,1 %) больному стабильной стенокардией. Перипроцедурных осложнений не выявлено. Госпитальная и 30-дневная летальность составила 0 %. Выживаемость пациентов на сроках до 9 лет – 99,2 %; отдаленная летальность – 0,8 %; сохранность результатов до 1, 2 и 3 лет наблюдения составила соответственно 90,5, 84,1 и 81,7 %, до 5–9 лет – 79,4 %. Активный образ жизни верифицирован у 74,6 % обследованных, щадящий – у 25,4 %, возврат к работе – у 86,5 %, транзиторные сексуальные нарушения – у 28,6 %. Медикаментозную терапию и диетический режим питания соблюдали 83,3 и 27,8 % пациентов. Продолжали курить и принимать энергетические напитки 34,1 и 23,8 % обследованных; избыточный вес и ожирение сохранялись у 23,8 и 19 %. Рецидив инфаркта миокарда (ИМ) / стенокардии отмечен у 23 % пациентов; повторные ЭВРМ выполнены 20,6 % больным. Депрессию из-за рецидива ИМ / стенокардии отмечали 23 % пациентов, ввиду карантина (COVID-19) – 18,3 %; 6,3 % страдали паническими атаками, боясь повторения ангинозных болей. Выводы. Предикторами повторных ЭВРМ и стабильности результатов являются: 1) ОКС; 2) возраст ≤35 лет; 3) анамнез ИМ, фракция выброса ≤35–40 %, диабет; 4) диаметр стентов <28 мм; 5) курение и прием энергетических напитков. Ведущий предиктор – агрессивность атеросклероза и диабета у лиц не старше 40 лет, обусловливающих: а) раннюю дисфункцию стентов; б) при сохранной проходимости стентов – поражение нативных и «защищенных» коронарных сосудов. Ключевые слова: ишемическая болезнь сердца, молодые больные, профиль риска, семиотика коронарных артерий, эндоваскулярная реваскуляризация миокарда, качество жизни.
