What is Chance of dying during single coronary bypass surgery?

The chance of dying during single coronary bypass surgery is typically low, but it can vary depending on several factors, including the patient's overall health, the severity of their heart condition, and the skill of the surgical team. According to the Society of Thoracic Surgeons (STS), the average mortality rate for isolated coronary artery bypass grafting (CABG), which involves bypassing a single blocked or narrowed coronary artery, is approximately 1.5% to 2%. However, this number can be higher or lower depending on individual circumstances.

Factors that can increase the risk of mortality during single coronary bypass surgery include:

1. Advanced age

2. Diabetes

3. Obesity

4. Kidney disease

5. Poor lung function

6. History of heart failure or previous heart surgery

7. Emergency surgery (as opposed to elective surgery)

On the other hand, patients who are younger, otherwise healthy, and undergoing elective bypass surgery have a lower risk of mortality. Additionally, the skill and experience of the surgical team play a significant role in patient outcomes. Hospitals and surgeons with higher volumes of CABG procedures tend to have better success rates.

It is important to note that the mortality rates mentioned above are general estimates, and individual patients may have a different risk profile. Before undergoing bypass surgery, patients should discuss their specific risks and expected outcomes with their doctor to make an informed decision about the best course of treatment.
