Brief Summary:
It is hypothesised that, in individuals being considered for cardiovascular preventative therapy, computed tomography coronary angiography guided management will reduce the future risk of coronary heart disease death or non-fatal myocardial infarction compared to management guided by the current standard of care, a cardiovascular risk score.

Condition or disease Intervention/treatment Phase
Cardiovascular Diseases Diagnostic Test: Computed tomography coronary angiography Other: ASSIGN Score Not Applicable

Detailed Description:
Prevention of cardiovascular disease is currently guided by probabilistic risk scores that both over and under treat individuals, commit most middle-aged people to pharmacotherapy, and have little evidence base. It has been demonstrated that use of computed tomography coronary angiography (CTCA) is associated with changes in the diagnosis and treatment of patients presenting with stable chest pain, and that this leads to a marked reduction in the future risk of myocardial infarction. Importantly, the proportionate reduction in coronary events was most marked in those with non-anginal chest pain irrespective of their cardiovascular risk score which again demonstrated poor discrimination. The research team propose a randomised controlled trial of at least 6,000 middle-aged individuals at risk of cardiovascular disease that will compare these two strategies of targeting preventative therapies: a probabilistic cardiovascular risk score, and screening with CTCA. This trial will determine if CTCA guided management will be associated with better targeted intervention, prevent over medicating the general population, and result in fewer future coronary heart disease events than the current standard of care using a cardiovascular risk score.

Primary Outcome Measures :
  1. Coronary heart disease death or non-fatal myocardial infarction [ Time Frame: 5 years ]
    The primary research objective of the trial is to determine whether, in individuals with risk for cardiovascular disease, coronary heart disease screening with CTCA is associated with a reduction in the rate of coronary heart disease death or non-fatal myocardial infarction when compared to a probabilistic cardiovascular risk score approach.

Secondary Outcome Measures :
  1. Death [ Time Frame: 5 Years ]
    Number of all-cause, cardiovascular, coronary heart disease and non-cardiovascular deaths

  2. Cardiovascular Events [ Time Frame: 5 Years ]
    Number of participants who have fatal and non-fatal myocardial infarction or stroke

  3. Cardiovascular Procedures [ Time Frame: 5 Years ]
    Number of Invasive coronary angiography and coronary revascularisation procedures

  4. Quality of Life (EQ-5D-5L) [ Time Frame: 2 Years ]
    Quality of life measured using EQ-5D-5L instrument

  5. Prescription [ Time Frame: 5 Years ]
    Rates of prescription of preventative therapies (anti-platelet, statin and angiotensin-converting enzyme inhibitor therapies)

  6. Lifestyle Modification [ Time Frame: 2 Years ]
    Uptake of lifestyle modifications (smoking, exercise and diet) measured using self-reported questionnaire

  7. Health Economics [ Time Frame: 2 Years ]
    Health economic assessment of cost-effectiveness

  8. Cholesterol [ Time Frame: 5 Years ]
    Serum cholesterol concentration

  9. Disadvantages of CTCA- Radiation [ Time Frame: 5 Years ]
    Radiation dose (mGy-cm)

  10. Disadvantages of CTCA- incidental findings [ Time Frame: 5 Years ]
    Number of participants with incidental findings from CTCA
