Comparison of Mortality Rate in Coronary Arterial Bypass Surgery: On-pump vs off-pump

Introduction

Coronary heart disease (CHD) is one of the leading causes of death worldwide, accounting for millions of deaths each year. The development of medical technology has enabled the treatment of CHD not only with drug therapy, but also with interventions such as Percutan Coronary Intervention (PCI) and Coronary Arterial Bypass (CABG) operations. The purpose of these two procedures is to improve the life expectancy and quality of life of patients. In the context of CABG surgery, there are two main techniques: on-pump and off-pump. The on-pump technique uses a heart-lung machine to pump blood during surgery, while the off-pump technique is done without the heart-lung machine. This study aims to compare the mortality rate and major cardiovascular events in patients who undergo CABG with these two techniques.

Background

Coronary heart disease is a complex condition that affects the blood vessels of the heart, leading to reduced blood flow and oxygen supply to the heart muscle. CABG surgery is a common treatment for CHD, which involves bypassing the blocked coronary arteries with a graft. The goal of CABG surgery is to restore blood flow to the heart muscle, improving the patient's quality of life and reducing the risk of heart attack and death.

Methods

This study involved 62 patients undergoing CABG surgery using both on-pump and off-pump techniques. The patients were selected from a database of patients who underwent CABG surgery at Adam Malik Hajj Hospital between 2018 and 2020. The study used a retrospective design, where data was collected from medical records and patient charts. The study outcomes were major cardiovascular events, including heart attack, stroke, and death, as well as bleeding complications.

Results

The results of this study show a significant relationship between CABG techniques and major cardiovascular events (p = 0.026; OR 6.5; CI 1.25-33.69). This means that patients undergoing CABG with on-pump techniques have a 6.5-times greater risk of experiencing major cardiovascular events compared to patients undergoing CABG with off-pump techniques. In addition, a significant relationship was found between CABG technique and bleeding complications (p = 0.05).

Discussion

The results of this study indicate that the CABG technique can affect the mortality rate and major cardiovascular events. The off-pump technique seems to have the advantage in reducing the risk of major cardiovascular events and bleeding complications. This may be because the on-pump technique involves the use of heart-lung machines, which can cause trauma in the heart and blood vessels.

Limitations

This study has several limitations that need to be considered when interpreting the results. Firstly, the sample size is relatively small, with only 62 patients. This may not be enough to generalize the results to the wider population. Secondly, the study used a retrospective design, which can lead to potential bias. Finally, there may be confounding factors, such as age, sex, and basic medical conditions, that can affect the results.

Conclusion

The results of this study indicate that off-pump techniques can be a safer choice for patients undergoing CABG. However, further research needs to be done with a larger sample size and a stronger design to validate these findings. Discussion with a cardiologist is very important to determine the most appropriate CABG technique for each individual.

Recommendations for Readers

  • Consult with a heart specialist: Make sure to discuss treatment options and risks associated with each CABG technique.
  • Research and search for information: Find information about various CABG techniques and the benefits and risks of each technique.
  • Follow the doctor's instructions: After undergoing CABG, obey the doctor's instructions and follow the recommended treatment plan.

Future Directions

Future studies should aim to investigate the long-term outcomes of patients undergoing CABG with on-pump and off-pump techniques. Additionally, studies should explore the potential benefits and risks of other CABG techniques, such as robotic-assisted CABG. By continuing to investigate the effects of CABG techniques on patient outcomes, we can improve the quality of care for patients with CHD.

Frequently Asked Questions (FAQs) about Coronary Arterial Bypass Surgery: On-pump vs off-pump

Q: What is coronary arterial bypass surgery?

A: Coronary arterial bypass surgery, also known as CABG, is a surgical procedure that involves bypassing blocked or narrowed coronary arteries with a graft. The goal of CABG is to restore blood flow to the heart muscle, improving the patient's quality of life and reducing the risk of heart attack and death.

Q: What are the two main techniques used in CABG surgery?

A: The two main techniques used in CABG surgery are on-pump and off-pump. The on-pump technique uses a heart-lung machine to pump blood during surgery, while the off-pump technique is done without the heart-lung machine.

Q: What are the benefits of off-pump CABG surgery?

A: The benefits of off-pump CABG surgery include reduced risk of major cardiovascular events, such as heart attack and stroke, and reduced risk of bleeding complications. Off-pump CABG surgery may also reduce the risk of trauma to the heart and blood vessels.

Q: What are the risks of on-pump CABG surgery?

A: The risks of on-pump CABG surgery include increased risk of major cardiovascular events, such as heart attack and stroke, and increased risk of bleeding complications. On-pump CABG surgery may also increase the risk of trauma to the heart and blood vessels.

Q: Who is a good candidate for off-pump CABG surgery?

A: Patients who are good candidates for off-pump CABG surgery are those who have a low risk of major cardiovascular events and bleeding complications. Patients who have a history of heart disease, high blood pressure, or other cardiovascular conditions may be good candidates for off-pump CABG surgery.

Q: What are the potential complications of CABG surgery?

A: The potential complications of CABG surgery include major cardiovascular events, such as heart attack and stroke, bleeding complications, and trauma to the heart and blood vessels. Patients who undergo CABG surgery should be closely monitored for these complications.
