Abstract
<p style="text-align:justify"><span style="font-size:medium"><span style="font-family:Aptos,sans-serif"><span style="color:#000000"><strong>Background:</strong> Inferior myocardial infarction (MI) with right ventricular (RV) involvement is frequently associated with conduction abnormalities, hemodynamic instability and adverse outcomes. This study aimed to evaluate long-term outcomes in patients with inferior MI and RV involvement. </span></span></span></p> <p style="text-align:justify"><span style="font-size:medium"><span style="font-family:Aptos,sans-serif"><span style="color:#000000"><strong>Methods:</strong> Retrospective, single-centre study, analysing consecutive patients admitted to a cardiac intensive care unit for inferior ST-segment elevation MI between 2015 and 2024. RV involvement was diagnosed by right precordial leads ST elevation ≥1 mm and/or echocardiographic evidence of dysfunction [tricuspid annular plane systolic excursion <18mm and RV systolic velocity on tissue Doppler< 10cm/s]. The primary endpoint was 1-year all-cause mortality. Secondary endpoints included heart failure hospitalization (HFH), ventricular arrhythmias, and RV systolic dysfunction during follow-up. Predictors of 1-year mortality and RV systolic recovery were explored in uni- and multivariate analysis. </span></span></span></p> <p style="text-align:justify"><span style="font-size:medium"><span style="font-family:Aptos,sans-serif"><span style="color:#000000"><strong>Results:</strong> From a total of 391 patients, 32% (n=127) had RV involvement, mostly identified by echocardiographic criteria (83%). The right coronary artery (RCA) was the culprit vessel in 86% of patients with RV involvement versus 68% without (p < 0.001). Cardiogenic shock occurred more frequently in the RV involvement group (18% vs. 6%, p < 0.001), and complete AV block was significantly more common (31% vs. 9%, p < 0.001), with 14% vs 4% requiring permanent pacemaker implantation (p = 0.01). In-hospital mortality was higher among patients with RV involvement (7% vs. 2%, p = 0.02). </span></span></span></p> <p style="text-align:justify"><span style="font-size:medium"><span style="font-family:Aptos,sans-serif"><span style="color:#000000">At 1 year, Kaplan–Meier analysis showed increased mortality in the RV involvement group (14% vs. 6%; log-rank p = 0.01). RV involvement was an independent predictor of 1-year mortality, after adjusting for age, LVEF, multivessel disease, incomplete revascularization and complete AV block (adjusted HR 1.7, 95% CI 1.09–2.66, p= 0.02). RV involvement also showed increased risk of HFH and ventricular arrhythmias during follow-up (HR 2.5 95% CI: 1.45–4.29, Log-rank p < 0.001 and HR: 2.7 95% CI: 1.17–6.39, Log-rank p = 0.02, respectively).</span></span></span></p> <p style="text-align:justify"><span style="font-size:medium"><span style="font-family:Aptos,sans-serif"><span style="color:#000000">Echocardiographic follow-up at 1 year (available in 85% of survivors) showed significant RV systolic recovery: TAPSE improved from 13.6 ± 2.8 mm to 18.2 ± 3.1 mm (p < 0.001) and RV S′ from 8.0 ± 1.8 cm/s to 10.5 ± 1.7 cm/s (p < 0.001). Overall, 74% of patients with RV involvement achieved RV systolic recovery at 1 year. Baseline RV dysfunction, incomplete revascularization, multivessel disease, and reduced LVEF all independently predicted RV non-recovery.</span></span></span></p> <p style="text-align:justify"><span style="font-size:medium"><span style="font-family:Aptos,sans-serif"><span style="color:#000000"><strong>Conclusions:</strong> Inferior MI with RV involvement poses higher risk of 1-year mortality, HF hospitalization and ventricular arrhythmias. Despite this, RV systolic recovery occurred in most patients, with baseline RV dysfunction, delayed or unsuccessful revascularization, multivessel disease, and reduced LVEF being key predictors of RV non-recovery.</span></span></span></p>
