This podcast explores two studies on how exercise can help reduce plaque buildup in the coronary arteries of people with existing heart disease. The first study involved 60 patients who participated in a six-month interval training program, which resulted in a 5% reduction in total plaque and a 1% decrease in percent atheroma volume (PAV). This finding is significant since even small reductions in PAV can lead to considerable decreases in risk. The second, smaller study compared interval training with continuous cardio (both maintaining the same calorie burn) over 12 weeks. While both groups showed a trend toward plaque reduction, there were notable statistically significant decreases in necrotic core size, a key indicator of vulnerable plaque. Together, these studies suggest that consistent exercise, whether interval-based or continuous, may effectively reduce plaque and enhance cardiovascular health. However, further research with larger participant groups and longer durations is essential to confirm these results and evaluate their impact on actual heart events. Always consult your doctor before starting a new exercise routine.
