Understanding Angina Symptom Trajectories After Invasive vs. Conservative Treatment | JACC Deep Dive

In this JACC Deep Dive, Dr. Harlan Krumholz highlights a study by Ikemura et al. that used data from the ISCHEMIA trial to model how angina symptoms evolve over three years in patients with stable coronary disease treated either invasively or conservatively. The study identified six distinct symptom trajectories, showing that while most patients improved over time, those undergoing revascularization were more likely to experience rapid and complete symptom relief. However, the benefit was not uniform—patients with frequent baseline angina saw the greatest improvement, and some had persistent symptoms regardless of treatment. These findings underscore the importance of personalized, shared decision-making based on a patient's likely symptom trajectory rather than a binary treatment choice.
