A normal screening result is reassuring, but it does not guarantee that a cardiac condition will never develop in the future. Some inherited heart conditions can develop or become more apparent as an individual gets older, particularly during adolescence and early adulthood.
Based on the latest recommendations from our clinical team at St George’s, the advised screening intervals are:
- Ages 14 to 21: screening every 3 years
- Ages 21 and over: screening every 5 years
These intervals reflect current evidence and clinical practice. The recommendation changes at age 21 because even adults diagnosed with cardiac conditions are typically reviewed every five years, making a five-year screening interval consistent with routine clinical follow-up.
While routine repeat screening is important, it is equally important to remain vigilant for symptoms that could indicate an underlying heart condition. Symptoms to be aware of include:
- Chest pain during exercise
- Unexplained breathlessness that is disproportionate to the amount of exercise being performed
- Palpitations
- Dizziness during exercise
- Blackouts during exercise
- Blackouts without warning
Anyone who develops these symptoms should seek medical advice, regardless of when they were last screened.
Individuals with a family history of an inherited cardiac condition may also require additional assessment or follow-up, based on the advice of their cardiologist or healthcare professional.
A normal screening result is reassuring, but if symptoms develop or there is a significant change in family history, further investigation may be needed before the next routine screening is due.
