Hidden dangers
Understanding the risks
Sudden Cardiac Death (SCD) is a devastating event that often occurs unexpectedly, but knowledge is our best defence. By identifying the specific risk factors for heart conditions linked to Sudden Cardiac Death, families and individuals can seek early intervention and prevent tragedy long term.
Underlying causes
Conditions that increase risk
While SCD can happen suddenly, it is often the result of underlying heart conditions that have gone undetected and increase the risk of heart failure or arrest
- Coronary Artery Disease (CAD) is the leading cause of SCD. It occurs when the arteries become narrowed or blocked, restricting the flow of blood to the heart muscle.
- Cardiomyopathy covers diseases of the heart muscle which reduce its ability to pump blood effectively. It can be a genetic condition or develop through issues like high blood pressure.
- Arrhythmias are significant irregularities in the heart’s rhythm. These electrical faults can disrupt the heartbeat.
- Inherited Cardiac Conditions, including Long QT Syndrome and Brugada Syndrome, affect the heart’s electrical system. These genetic predispositions increase the risk of sudden death, even in structurally normal hearts.
Personal & environmental factors
Understanding your risks
Recognising personal and environmental factors is crucial for early diagnosis and effective prevention, particarly for family members of those affected. Below are risk factors for Sudden Cardiac Death.
- A family history of unexplained sudden death or heart disease. Similarly, those with existing conditions like heart failure or previous heart attacks require close monitoring.
- Risk generally rises with age and is statistically higher in men. However, lifestyle choices, including smoking, poor diet, and inactivity, are factors that heavily influence heart health.
- While SCD can be silent, symptoms like chest pain, breathlessness, palpitations, or unexplained fainting should never be ignored.
- Prevention is possible. Regular check-ups and simple screening tests, such as an ECG, can detect hidden heart defects before a cardiac arrest occurs.
