Coronary Artery Disease

Other names: Ischaemic heart disease, IHD, CAD, atherosclerosis

Basic overview

Atherosclerosis may be asymptomatic for decades, but eventually the plaques may cause a significant narrowing of the heart arteries – restricting blood supply to the heart muscle – resulting in angina (usually with exercise / physical activity), or if this occurs suddenly (i.e. vessel occlusion) it will cause a ‘heart attack’

Risk factors for atherosclerosis include: being overweight, diabetes, smoking, lack of physical exercise and a poor diet


If the atherosclerotic plaque has not narrowed the arteries to a significant degree (usually at least 70%) then there may be no symptoms at all

Angina can present differently depending on the person, especially in diabetic patients. Classically, angina is described as a central chest pressure / tightness that may radiate to the arm or jaw. It is triggered by exercise and relieved with rest (except in the case of a sudden heart attack)


Lifestyle modifications:

  • Healthy eating (Mediterranean diet), especially in order to lose weight if your BMI is >25
  • Salt restriction (less than 4g daily)
  • Limitation of alcohol intake (no more than two standard drinks a day for men and one for women, with at least 2 alcohol-free days a week)
  • At least 30 minutes of moderate intensity exercise daily
  • Avoidance of smoking


There are many classes of medications, but the most commonly prescribed medications include: 

  • Anti-platelet medications (such as aspirin)
  • Cholesterol-lowering medications (such as statins)
  • Anti-anginal medications (such as beta-blockers, nitrates, calcium channel blockers or nicorandil)


For patients with significant symptoms despite medications or with very severe vessel narrowing, an intervention may be required:

  • Stent
  • Coronary Artery Bypass Grafting
