Acute Inferior Myocardial Infarction

Background: The patient with inferior wall AMI, site of culprit lesions is an important determinant of outcome. Patient with RV infarction have a poor prognosis whereas those with occlusion of LCX have a good prognosis. Early diagnosis and treatment substantially reduce cardiac events particularly in high-risk patients. V4R can be used as to locate the site of obstruction. Materials and methods: 81 patients with acute inferior myocardial infarction admitted to the coronary care unit (CCU) within 12 hours after the onset of chest pain who underwent coronary angiogram were included in the study. Standard 12-lead ECG with right precordial lead V4R was recorded. Patients were categorized into within 3 groups according to early changes of V4R-Group- I - ST-segment elevation > 1 mm and positive T- wave, Group-II- ST-segment iso-electric and positive T-wave, Group-III- ST-segment depression >1 mm and negative T -wave. Results: In group I patients, highest percentage of the patients had lesion in proximal RCA (97.2%); whereas in group II patients, highest percentage in the distal RCA (89.7%) followed by LCX (41.4%) and in group III patients, highest percentage also in LCX (100.0%) followed by LAD (56.3%). Based on analysis of sensitivity and specificity, it was revealed that in group I patients of ECG finding suggested 100.0% sensitivity, 97.8% specificity and 98.8% accuracy. In group II patients, 92.9% sensitivity, 94.3% specificity and 93.8% had accuracy. In case of group III patients, 93.8% sensitivity, 98.5% specificity and 97.5% accuracy. Conclusion: The configuration of the ST-T segment in lead V4R is a sensitive and specific tool to recognize the occluded vessel in acute inferior MI whether it is proximal RCA, distal RCA or LCX. Since it is an inexpensive method, it can be readily used to locate the site of occlusion in AMI - Inferior. Keywords: Coronary artery disease; Myocardial infarction;, Lead V4r.

Background: The clinical implications of precordial ST segment depression (PSTD) during acute inferior myocardial infarction has been an area of debate, and still under investigation with conflicting results. Based on previous studies, the presence of PSTD defines a high risk subset of patients with acute inferior myocardial infarction due to a more extensive myocardial ischemia that lead to a higher incidence of major adverse cardiovascular events (MACE). Despite of these results, others still considered this ECG finding as a benign electrical phenomenon. The aim of this study is to compare the incidence of in-hospital MACE in patients of acute inferior myocardial infarction with or without PSTD and to know whether PSTD can be used as a predictor of in-hospital MACE in acute inferior myocardial infarction.Methods: A total of 96 acute inferior myocardial infarction patients admitted from December 2013-2015 at Cardiology Department of Haji Adam Malik General Hospital were retrospectively analyzed. Patients were divided into two groups based on the presence of PSTD on admission ECG. Bivariate and multivariate analyses were performed to study the association between PSTD and in-hospital MACE, p value<0.05 was considered statistically significant.Results: The bivariate analysis showed that in-hospital MACE was significantly higher in patients of acute inferior myocardial infarction with PSTD than without PSTD (92% vs 8%, p<0.001). On multiple logistic regression analysis, patients of acute inferior myocardial infarction with PSTD have a 5.4 fold increased risk of in-hospital MACE than patients without PSTD (OR 5.480; 95% CI 1.759-17.067, p=0.003).Conclusion: The presence of precordial ST segment depression on admission ECG in acute inferior myocardial infarction patients was associated with a higher in-hospital MACE and was an independent predictor of in-hospital MACE.

Patients of acute inferior myocardial infarction, in addition to the ST segment elevation in inferior leads often have ST segment depression in the precordial leads. This study was performed to observe the incidence of these ‘reciprocal’ ST changes. One hundred consecutive acute inferior myocardial infarction patients were included in the study. They were further allocated to two electrocardiographic groups. Group 1 consisted of patients of acute inferior myocardial infarction with precordial ST segment depression & Group 2 consisted of patients of acute inferior myocardial infarction without precordial ST segment depression. Among the 100 consecutive patients, a large number of patients were included in group 1 (76%). Significant number of patients of group 1 belonged to the age group of above 60 years compared to group 2 (27.6% vs. 4.2%; p < .02). Conversely significantly higher number of younger patients ≤ 40 years belonged to group 2 (41.7% vs. 11.9%; p < .01). Mean ST segment elevation (mm) was also significantly higher in group 1 than group 2 (4.07 ± 1.93 vs. 2 ± 0.78; p <.001). The patients of acute inferior myocardial infarction thus show a significant number of ST segment depression in their precordial leads. In different studies these subset of patients showed increased morbidity and mortality. Key words: acute inferior myocardial infarction; precordial ST segment depression.
