Key facts
The essentials at a glance.
The symptoms to recognise, when to seek help, which specialist to see, and what treatment usually involves.
-
Who it helps most: people at intermediate risk who are unsure about statins, or with a family history that standard calculators handle badly
-
A calcium score is not for diagnosing chest pain - symptomatic patients need a different pathway, usually CT coronary angiography
-
Specialist: a consultant cardiologist usually leads assessment and treatment
-
A score of zero supports deferring medication in many cases; scores above 100, or above the 75th centile for age, generally tip the balance towards statins and tighter risk control
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The scan takes minutes, needs no needles or dye, and counts calcium deposits that mark established atherosclerosis. Its power lies in reclassification: a zero score identifies people whose short-to-medium-term risk is genuinely low, while a high score reveals disease that risk calculators built on averages would miss entirely.
Diagnosis and treatment routes
The score has limits - it cannot see soft, non-calcified plaque, so it does not rule out disease in younger people or exclude the cause of symptoms. Used in the right group, and interpreted by a cardiologist alongside your cholesterol, blood pressure and family history, it turns an abstract percentage into a concrete, personal decision. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a consultant cardiologist. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
