Abstract

Objective: To describe the clinical, subclinical and coronary artery damage characteristics of patients ≥75 years old with acute ST elevation myocardial infarction. Subjects and methods: Interventional, prospective, cross-sectional study was conducted on 104 patients aged ≥75 years, diagnosed with acute ST elevation myocardial infarction, and indicated for primary percutaneous coronary intervention at the Vietnam National Heart Institute - Bach Mai Hospital, Hanoi Heart Hospital, Huu Nghi Hospital from 2018-2023. Results: The proportion of patients aged 80-89 years was 51.0%, ≥90 years old was 8.7%, male was 64.4%. The proportion of typical chest pain was 63.4%; dyspnea was 89.4% and fatigue was 93.3%. The Killip grade III was 11.5% and grade IV was 1.9%. The average concentration of NT-proBNP was 3052.47±5499.18ng/dl. The proportion of sinus rhythm was 90.4%; atrial fibrillation was 8.7%, atrioventricular block 9.6%. Posterior infarction was 39.4%; anterior wall was 38.5%. The proportion of regional movement disorders was 47.1%; EF <50% was 33.7%. The proportion of damage to 4 coronary branches was 3.8%; 3 branch damage was 26.0% and 2 branch damage was 38.5%. The location of damage is anterior interventricular artery 81.7%; right coronary artery 60.6%; circumflex artery damage 46.2%. The proportion of TIMI 0 flow before intervention was 43.3%; TIMI 1 was 41.3% and TIMI 2 was 15.4%. Conclusion: Patients aged ≥75 years with acute ST elevation myocardial infarction have mainly damage to 2 or more branches and the main of damage is the anterior interventricular artery
