Cardiac screening

The Singapore Heart Foundation states that 17 men and women die every day from heart problems. Coronary artery disease, atherosclerosis, high blood pressure, and stroke are the most common heart conditions reported in Singapore. Cardiac Screening can help with early identification, management, and prevention of these diseases.

We have several comprehensive packages available for screening, however these can also be customized after a discussion with Dr MacDonald.

High Blood Pressure

Hypertension. An incredibly common condition that usually has no symptoms and if left untreated can lead to kidney failure, blindness, heart attacks and strokes.

Coronary Heart Disease

  • Atherosclerosis – the process where fatty plaques build up in the artery walls.
  • Angina – when the fatty plaques cause severe blockages that cause chest tightness at times of stress
  • Heart attack – When a fatty plaque ruptures and blocks the artery causing severe pain and sometimes sudden death


  • Ectopics – extra heart beats caused by premature firing of the heart.
  • SVT – Fast heart rhythm originating in the atria
  • VT – Fast and dangerous heart rhythm originating in the ventricles
  • Atrial fibrillation – Common, irregular heart rhythm that increases the risk of having a stroke.

Heart Failure

Heart failure. Commonly caused by heart attacks and high blood pressure, but can also be inherited from your parents. The heart fails to pump blood properly causing breathlessness, ankle swelling and early death if not treated.

Valvular heart disease

  • Mitral regurgitation – Leaky mitral valve
  • Aortic stenosis – Narrowed aortic valve sometimes due to a bicuspid aortic valve,
  • Aortic regurgitation – Leaky aortic valve
  • Mitral stenosis – Narrowed mitral valve, often caused by rheumatic fever.
