Comparison of Bleeding and Major Cardiovascular Events between the Use of Enoxaparin and Fondaparinux in Patients with Acute Myocardial Infarction without the Elevation of the ST Segment with Type 2 Diabetes Mellitus
Background
Acute myocardial infarction without the elevation of the ST (IMA-nest) segment is a complex condition that often accompanies various comorbidities, including Diabetes Mellitus type 2 (DMT2). Patients with DMT2 are at a higher risk of experiencing cardiovascular disease, with a 2 to 4 times increased risk compared to individuals without diabetes. This increased risk is attributed to hemostasis disorders that occur in DMT2, such as platelet hyper-reactivation, hypercoagulation, and decreased fibrinolysis function. These conditions can reduce the effectiveness of anticoagulants, thereby increasing the risk of stent thrombosis, the need for revascularization, and recurrent infarction and major cardiovascular events (KKVM). Therefore, it is essential to assess the effects of commonly used anticoagulants, namely enoxaparin and fondaparinux, in IMA-nest patients with DMT2.
The Importance of Choosing the Right Anticoagulant
The choice of anticoagulant is crucial in managing patients with IMA-nest and DMT2. Enoxaparin and fondaparinux are two commonly used anticoagulants that have different mechanisms of action and side effect profiles. Enoxaparin is a low molecular weight heparin that inhibits factor Xa and thrombin, while fondaparinux is a synthetic pentasaccharide that selectively inhibits factor Xa. Understanding the effects of these anticoagulants on bleeding and KKVM events is essential in making informed decisions about patient care.
Research Methods
This study involved 67 patients diagnosed with IMA-nest with DMT2 who were treated at HAM Hospital during the period January to October 2018. Patients were divided into two groups based on the types of anticoagulants used: enoxaparin and fondaparinux. Observations were carried out on bleeding and KKVM events, including mortality, acute heart failure, cardiogenic shock, malignant arrhythmia, and stroke. Statistical analysis was conducted using the Chi-Square test or Fisher Exact test to determine the comparison between the two groups.
Research Results
The study found that the majority of patients (76%) were men with an average age of 55 years. The ECG results showed that the enoxaparin group experienced more depression of ST in the initial presentation compared to the fondaparinux group (88% vs. 64.7%, p = 0.026). Minor bleeding occurred in 7 (10.4%) patients, with no statistically significant difference between the two groups (RR 2,576; p value 0.259).
In KKVM analysis, 26 (38.8%) patients experienced KKVM events, including heart failure, cardiogenic shock, malignant arrhythmia, and stroke. The comparison between the two groups showed a significant difference (RR 1,946; p value 0.035). Specifically, the enoxaparin group showed a higher event rate for heart failure compared to fondaparinux (RR 2,833; p value 0.034), while the incidence of cardiogenic shock, malignant arrhythmia, and stroke did not show a significant difference between the two groups.
Conclusion
This study found that there were no significant differences in terms of side effects of bleeding between the use of enoxaparin and fondaparinux during treatment. However, fondaparinux showed a lower KKVM level compared to enoxaparin in IMA-nest patients with DMT2. This finding is important for clinical practice in choosing the right anticoagulants for patients with similar conditions. Although this result can be influenced by several factors not identified in this study, it is essential to consider the risks and benefits of using enoxaparin and fondaparinux in managing patients with IMA-nest and DMT2.
Implications for Clinical Practice
A better understanding of the risks and benefits of using enoxaparin and fondaparinux can improve the quality of patient care with acute myocardial infarction and diabetes mellitus. Clinicians should consider the individual patient's risk factors and comorbidities when choosing an anticoagulant. This study highlights the importance of further research into the effects of anticoagulants on bleeding and KKVM events in patients with IMA-nest and DMT2.
Future Directions
Future studies should investigate the long-term effects of enoxaparin and fondaparinux on bleeding and KKVM events in patients with IMA-nest and DMT2. Additionally, studies should explore the impact of other factors, such as patient age, sex, and comorbidities, on the choice of anticoagulant. By understanding the complex interactions between anticoagulants and patient factors, clinicians can make informed decisions about patient care and improve outcomes for patients with IMA-nest and DMT2.
Limitations of the Study
This study had several limitations, including a small sample size and a short follow-up period. Additionally, the study did not control for other factors that may have influenced the results, such as patient age, sex, and comorbidities. Future studies should address these limitations and explore the effects of enoxaparin and fondaparinux on bleeding and KKVM events in a larger and more diverse population.
Conclusion
In conclusion, this study found that fondaparinux showed a lower KKVM level compared to enoxaparin in IMA-nest patients with DMT2. This finding is important for clinical practice in choosing the right anticoagulants for patients with similar conditions. By understanding the risks and benefits of using enoxaparin and fondaparinux, clinicians can make informed decisions about patient care and improve outcomes for patients with IMA-nest and DMT2.Frequently Asked Questions (FAQs) about Enoxaparin and Fondaparinux in Patients with Acute Myocardial Infarction without the Elevation of the ST Segment with Type 2 Diabetes Mellitus
