Can Exercise Reduce Existing Heart Plaque?

Introduces exercise benefits for heart health and questions if it can reduce existing plaque in heart disease.

Details a study with 60 men with heart disease, on usual medical care, split into a control group and an exercise group.

Describes the interval training program focusing on treadmill and stationary bikes, tailored to individual limitations.

Findings showed a 5% reduction in total plaque burden and a 1% decrease in percent atheroma volume after 6 months of exercise.

Discusses a previous study comparing interval training with continuous cardio, noting similar plaque reduction in both groups.

Discusses possible mechanisms through which exercise may reduce plaque, including increased shear stress on artery walls.

Highlights the need for longer trials to connect plaque reduction to heart attack and stroke reduction; advises consulting a doctor before starting new exercise routines.
