“…Another study in our local population by Saif M et al 15 observed 28.0% RVI in patients with acute IWMI. Barrillon et al 16 highlighted the increased risk of conduction problems in patients with RV involvement, while a study conducted by Zehender et al 17 reported a higher incidence of ventricular fibrillation and sustained ventricular tachycardia in patients with RV involvement as indicated by ECG. Mehta et al 18 conducted a largescale study that compared clinical manifestations and outcomes of patients with acute myocardial infarction based on right ventricular involvement.…”

Objectives: Right ventricular infraction has prognostic significance in the setting of acute “inferior wall myocardial infarction (IWMI)”, this research is intended to determine the frequency of “right ventricular infarction (RVI)” in patients with acute IWMI. Methodology: This descriptive cross-sectional study took place at a tertiary care hospital in Peshawar, Pakistan. The study included consecutive patients who were diagnosed with acute IWMI. The presence of RVI was determined based on specific ECG findings showing >1.0mm ST segment elevation on right-sided chest leads. Results: In a sample of 150 patients, 87 (58%) were male. The average age of the patients was 61 ± 10.7 years. Among the patients, 111 (74%) had hypertension, 64 (42.7%) were diabetic, and 45 (30%) were smokers. A body mass index (BMI) exceeding 25 kg/m2 was observed in 83 (55.3%) patients. RVI was observed in 62 (41.3%) of the patients. The occurrence of RVI did not show statistically significant differences between males and females (41.4% vs. 41.3%; p=0.989), hypertensive and non-hypertensive individuals (41.4% vs. 41.0%; p=0.964), diabetics and non-diabetics (42.2% vs. 40.7%; p=0.855), smokers and non-smokers (42.2% vs. 41.0%; p=0.885), and patients with BMI ≤25 kg/m2 and >25 kg/m2 (41.8% vs. 41.0%; p=0.920), respectively. Conclusion: Based on the research findings, it can be concluded that RVI is a relatively common occurrence in patients with acute IWMI, as it was observed in more than 40% of the patients studied. However, no statistically significant association exists between RVI and various demographic and clinical factors.

“…A study in a dog model [32] demonstrated a marked deterioration in the RV end-diastolic size, systolic pressure, and contraction in cases of RCA ligation with isolated ligation of the right atrial branch. sustained ventricular tachycardia, all leading to higher mortality rates [33], were found more often in patients with RVI [9,[11][12][13]34]. Complete SA or AV blocks leading to bradycardia and loss of atrioventricular synchrony account in part for the ventricular dysfunction [35] and the development of hypotension and shock [36].…”

“…The clinical presentation of RVI varies from no hemodynamic compromise to cardiogenic shock and multi-organ failure [1,3,7,8,]. Right ventricular involvement in inferior-wall infarction is associated with higher rates of major complications and increased in-hospital-mortality [2,3,7,[9][10][11][12][13][14]. Although the short-term prognosis for RVI is poor, patients who survive the hospitalization show better long-term prognosis compared to patients with shock due to LV failure [15].…”

Background: Acute right ventricular infarction (RVI) is associated with hemodynamic and electrical complications and worse prognosis. The ability to predict which patients with inferior wall ST-elevation MI will develop right ventricular cardiogenic shock is limited.Methods: Consecutive patients admitted with STEMI secondary to occlusion of the right coronary artery were retrospectively analyzed. The association between demographic, angiographic and clinical characteristics and the development of cardiogenic shock due to right ventricular failure was evaluated. The accuracy of angiographic factors for the prediction of cardiogenic shock was assessed.Results: Out of 152 patients, 14 (9.21%) developed cardiogenic shock because of right ventricular failure. Three of them (21.42%) died during hospitalization. There were no deaths in patients without cardiogenic shock. In the cardiogenic shock group, 92.9% of patients had aculprit lesion in the proximal RCA and 78.6% of patients had multi-vessel coronary disease, compared to 42.8% and 39.1%in patients without shock. Proximal RCA occlusion, multivessel coronary disease, and failure of reperfusion were independent predictors for cardiogenic shock (ORs 15.7, 5.3 and 4.7 respectively). Conclusion:A culprit lesion in the proximal right coronary artery, the presence of multi-vessel disease and failure of reperfusion are strong predictors for the development of cardiogenic shock in patients presenting with inferior wall STEMI. Identification of these simple variables routinely available in the diagnostic angiogram performed upon admission may warrant careful and prolonged monitoring in the ICU, in order to identify early signs of cardiogenic shock.
