E488 • Sep 1, 2026 • 13 mins

In this episode, Dr. Chi-Ming Chow begins with insights from a dietitian on the relationship between diet and sleep, exploring foods and dietary factors that influence sleep quality. He delves into the TARGET-CTCA study, examining the role of CT coronary angiography in acute coronary syndrome and its implications for patient care. The episode also addresses the potential cardiovascular risks associated with xylitol. Dr. Chow discusses challenges in subspecialist capacity and explores potential solutions to address these issues. The episode concludes with a wrap-up and closing remarks, emphasizing the importance of these health topics.

Key Points

  • Maintaining steady blood sugar levels through a balanced diet of lean proteins, slow-digesting carbohydrates, and healthy fats can improve sleep quality and prevent energy crashes.
  • The TARGET-CTCA study found no significant difference in cardiac outcomes between patients receiving routine CT coronary angiography and those receiving standard care after a heart attack has been ruled out.
  • A new study suggests a potential link between high blood levels of the artificial sweetener xylitol and an increased risk of cardiovascular events, though further research is needed to confirm these findings.
