“…We thought it was probably due to a higher prevalence of CAD risk factors, however, we did not find any statistically significant differences regarding these risk factors between both groups, except for hypertension. Similarly, Nour et al found no differences in CAD risk factors between patients with and without PSTD 16 . Consistent with the findings of previous studies, our results showed that the presence of PSTD in inferior MI was associated with a more extensive myocardial ischemia or a larger infarcts as evidenced by a higher level of cardiac enzymes, a lower mean LVEF, and therefore, the rate of MACE (acute heart failure) as represented by KILLIP class ≥ 2 was also higher 3,5-7. We found statistically differences between the two groups concerning the onset of MI.…”

“…In this study, the proportion of inferior MI patients with PSTD was 54%, and this number was almost similar as reported by Sato et al with 60%2. Previous studies demonstrated that patients with PSTD had more complex CAD than patients without PSTD 16 . We thought it was probably due to a higher prevalence of CAD risk factors, however, we did not find any statistically significant differences regarding these risk factors between both groups, except for hypertension.…”

“…Second, the mechanism of PSTD in inferior MI is best described by using the concept of "ischemia at a distance" which suggested that an acute occlusion of the right coronary artery (RCA) may produce ischemia in the myocardium supplied by left anterior descending artery (LAD) if it has significant stenosis and depends on collateral blood flow from the RCA 13,14 . Precordial ST segment depression represent a concomitant anterior ischemia due to LAD disease (multivessel coronary artery disease in inferior MI) [15][16][17][18] . Thus, two mechanisms with different pathophysiologic bases may produce the same ECG pattern.…”

Background: Whether a precordial ST segment depression (PSTD) is merely a benign electrical phenomena or a sign of multivessel coronary artery disease (MVCAD) in inferior myocardial infarction (MI) remains unclear. The objective of this study is to analyze the complexity of coronary artery disease (CAD) in inferior MI patients with PSTD and to investigate whether PSTD can be used as a predictor of MVCAD in inferior MI. Methods: Patients with inferior MI were divided into two groups based on the presence of PSTD on admission ECG and were compared based on the patient's coronary artery complexities. Results: A total of 215 patients with inferior MI were found in this study period, with 102 patients meet the inclusion and exclusion criteria. Patients with PSTD had a higher incidence of MVCAD and SYNTAX score. Further analyzes showed PSTD on admission ECG was an independent predictor of MVCAD in inferior MI [45 (66%) vs 23 (34%); OR 4.097; 95% CI 1.638-10.247; p=0.003). Conclusion: In daily clinical practice, PSTD on admission ECG may serve as a simple noninvasive tool for predicting MVCAD or a more complex CAD in inferior MI.

Background; Magnesium has been implicated in the pathogenesis of acute myocardial infarction and its related complication like arrhythmia. Magnesium helps in myocardial metabolism, inhibits calcium accumulation and myocardial cell death. It has role in improving the vascular tone, peripheral vascular resistance, after load and cardiac output, reduces cardiac arrhythmias and improves lipid metabolism. Magnesium reduces vulnerability to oxygen derived free radicals, improves endothelial function and inhibits platelet function including platelet aggregation and adhesion. Objective: To know the relationship between the serum magnesium levels and arrhythmias in patients with acute myocardial infarction.70 cases of acute myocardial infarction, admitted in a tertiary care hospital over a period of 2 years i.e., between October 2015 to October 2017. Results: There is a signicant difference in the magnesium levels in patients with arrhythmias and without arrhythmias. Conclusion: In acute myocardial infarction, patients with low magnesium levels are more prone to get arrhythmias. That is the reason magnesium treatment can be considered in patients of acute myocardial infarction with low magnesium levels.
