Comparison of Myocardial Blush Grade in Patients with Acute Myocardial Infarction of ST Segment Elevation with and without Resolution Depression ST Segment of ST Reciprocals Undergoing Primary Percutaneous Coronary Interventions

Introduction

Acute coronary syndrome (ACS) is a major challenge in the field of cardiovascular health, with acute myocardial infarction with ST segment elevation (STEMI) being a life-threatening condition. Primary percutaneous coronary intervention (PCI) is a recommended procedure by the European Society of Cardiology (ESC) to improve blood flow to the heart, thereby reducing morbidity and mortality. However, in some cases, the depression of the ST segment (DSST) occurs in areas opposite to the infarction, making it essential to analyze the myocardial blush grade (MBG) to evaluate the effectiveness of myocardial reperfusion in patients with STEMI.

The Importance of Myocardial Blush Grade

Myocardial blush grade (MBG) is a critical parameter in evaluating the success of primary PCI in patients with STEMI. It reflects the effectiveness of myocardial reperfusion and is closely related to the patient's outcome. A higher MBG value indicates better myocardial reperfusion, which can lead to improved recovery after infarction, reduced morbidity, and mortality. Therefore, assessing the differences in MBG between patients with and without resolution of DSST reciprocal is essential to optimize therapeutic strategies.

Methodology

This study employed a retrospective cohort design, involving 67 STEMI patients who underwent primary PCI in three hospitals in Medan, Indonesia, between October 2018 and the study period. All patients were evaluated using MBG after the procedure and electrocardiographic examination to detect changes in DSST on the reciprocal lead before and 90 minutes after PCI. Statistical analysis was performed to compare MBG between patients with resolution of DSST reciprocal and without resolution.

Results

The study found that 35 patients experienced resolution of DSST reciprocal with an MBG value of 3, while 32 other patients did not experience resolution with an MBG value ≤2. The analysis showed a significant difference related to the location of the infarction (p = 0.001) and the classification of Killip (p <0.005). Furthermore, there was a significant difference between MBG in patients with resolution of DSST reciprocal compared to without resolution (p <0.001).

Discussion

The results of this study indicate that the resolution of DSST reciprocal is closely related to an increase in MBG, which reflects the effectiveness of better myocardial reperfusion. This is a crucial finding, as patients with higher MBG values have the potential to achieve better recovery after infarction, leading to decreased morbidity and mortality. The classification of Killip, which also shows a significant difference, highlights the importance of comprehensive evaluation of STEMI patients, including analysis of electrocardiographic and MBG changes, for optimizing therapeutic strategies.

Conclusion

In conclusion, this study demonstrates a significant difference between Myocardial Blush Grade in patients who experience resolution DSST reciprocal compared to those who do not, after undergoing primary percutaneous coronary interventions. This discovery emphasizes the importance of monitoring and proper management to increase results in patients with STEMI. The findings of this study can contribute to the development of more effective therapeutic strategies for STEMI patients, ultimately improving patient outcomes.

Recommendations

Based on the results of this study, the following recommendations can be made:

Comprehensive evaluation of STEMI patients should include analysis of electrocardiographic and MBG changes to optimize therapeutic strategies.
Monitoring and proper management of patients with STEMI are essential to increase results and improve patient outcomes.
Further research is needed to investigate the relationship between DSST reciprocal and MBG in patients with STEMI.

Limitations

This study has several limitations, including:

Small sample size: The study involved only 67 patients, which may limit the generalizability of the findings.
Retrospective design: The study employed a retrospective cohort design, which may be subject to biases and limitations.
Limited follow-up: The study did not have a long-term follow-up, which may limit the understanding of the long-term effects of DSST reciprocal and MBG on patient outcomes.

Future Directions

Future studies should aim to:

Investigate the relationship between DSST reciprocal and MBG in patients with STEMI using larger sample sizes and prospective designs.
Develop more effective therapeutic strategies for STEMI patients based on the findings of this study.
Conduct long-term follow-up studies to understand the long-term effects of DSST reciprocal and MBG on patient outcomes.
Frequently Asked Questions (FAQs) about Myocardial Blush Grade in Patients with Acute Myocardial Infarction of ST Segment Elevation
