Guide for Patients with Coronary Atherosclerosis

Coronary atherosclerosis is an accumulation of fatty deposits in the coronary artery wall. As coronary atherosclerosis progresses, this leads to gradual narrowing of the coronary arteries that are responsible for supplying nutrient to the muscle of the heart.

  • Aerobic exercises such as brisk walking, jogging or swimming, is the best type of exercise for heart health. Walking is the safest form of exercise to start if you are uncertain of the level of intensity.

    • Healthy adults should ideally complete at least 150 minutes a week of moderate intensity exercise (e.g. brisk walk). Seek your doctor’s advice for suitable physical exercise tailored to your condition.
    • Inactive adults should start gradually, with light or moderate intensity at a shorter duration (<10 min), with sessions spread throughout the week.
  • Get 6 to 8 hours of sleep daily. Inadequate sleep of ≤ 4 hours or excess sleep ≥ 10 hours has been linked with increased risk of coronary artery disease.
