Leading expert in cardiac surgery, Dr. Jürgen Ennker, MD, discusses the risk of stroke during heart surgery and how it can be predicted. He highlights the importance of monitoring white blood cell (WBC) counts as a potential indicator of increased stroke risk. Dr. Ennker explains that elevated WBC counts may signal altered hemostasis and blood flow, which are risk factors for cerebral stroke. By measuring WBC counts, healthcare providers can take precautions to reduce stroke risk and improve patient outcomes. Dr. Anton Titov, MD, facilitates the discussion, emphasizing the significance of predicting stroke risk in cardiac surgery patients.

Importance of Stroke Risk Prediction
Dr. Jürgen Ennker, MD, emphasizes the critical need to predict stroke risk in cardiac surgery patients. Stroke is a feared complication that can have devastating consequences. By identifying patients at higher risk, healthcare providers can implement strategies to minimize the likelihood of stroke and improve surgical outcomes.
White Blood Cell Counts and Stroke Risk
Dr. Ennker explains that elevated white blood cell (WBC) counts before heart surgery may indicate an increased risk of stroke. A higher WBC count can suggest altered hemostasis and blood flow, both of which are risk factors for cerebral stroke. Monitoring WBC counts allows for early intervention and risk mitigation.
Advanced Surgical Techniques
Dr. Ennker discusses how advanced surgical techniques, such as off-pump coronary artery bypass grafting, have significantly reduced the risk of stroke during heart surgery. These techniques help minimize complications and improve patient safety, highlighting the importance of continuous innovation in cardiac surgery.
Patient-Related Factors
Dr. Ennker notes that patient-related factors, including baseline WBC counts, play a crucial role in assessing stroke risk. A strong increase in WBC counts may necessitate additional precautions, such as blood dilution, to manage stroke risk effectively. Understanding individual patient profiles is essential for tailored care.
Preparing for Surgery
Dr. Ennker emphasizes the importance of thorough preparation for patients with elevated stroke risk. By identifying risk factors early, healthcare providers can implement targeted interventions to reduce stroke risk and enhance surgical outcomes. This proactive approach is vital for achieving better patient results.

Dr. Anton Titov, MD: Stroke is a risk factor in cardiac surgery. You have published important research. It found that higher than usual white blood cell (WBC) count, the leukocyte count, before the heart surgery might signify increased risk of stroke after surgery. Stroke after cardiac surgery is a very devastating complication. Stroke is a very feared complication. Through advanced use of surgical techniques, the risk of stroke decreased.
Dr. Jürgen Ennker, MD: There is off-pump coronary artery bypass grafting. As you mentioned, you decrease the risk of stroke significantly. But predicting patients who are at increased risk of stroke is very important.
Dr. Anton Titov, MD: Please tell us more about your work. How can you predict the risk of stroke in patients? Can stroke risk be predicted by white blood cell count numbers?
Dr. Jürgen Ennker, MD: Yes, again, you have patient-related factors. White cell count is one of them. You may have an increase in the white cell count. You have altered hemostasis, and the blood flow is different. This is one of the risk factors that may lead to an increased risk of cerebral stroke. We are measuring the white blood cell count, and we can prepare adequate precautions to diminish the risk of stroke. We aim to have a better patient outcome.
Dr. Anton Titov, MD: Is there a particular WBC leukocyte count range when you start to get concerned? Does it depend on what is the patient’s white blood cell count at a baseline? How do you assess that?
Dr. Jürgen Ennker, MD: If you have a strong increase in the white cell count, we have to dilute the blood. We have to look for other risk factors. We have to prepare the patient even more than usual.
