Cardiovascular prevention, Johannesburg
Cardiovascular risk assessment in Johannesburg.
Most heart attacks and strokes develop over years. A structured risk assessment aims to identify that risk while it is still modifiable.
In short
A cardiovascular risk assessment estimates the likelihood of future atherosclerotic cardiovascular disease using established factors such as age, blood pressure, smoking, diabetes and lipids, then selectively adds markers such as ApoB, lipoprotein(a) or coronary artery calcium when they are likely to reclassify risk or change treatment. No single blood test or scan provides the full answer.

The approach
Understand first. Then treat.
Heart attack and stroke prevention begins with established risk factors, not with expensive imaging. Blood pressure, smoking, diabetes, cholesterol, kidney disease, age and family history remain the foundation.
Additional testing becomes useful when the standard picture leaves genuine uncertainty. ApoB can clarify particle burden, Lp(a) identifies inherited risk, and coronary artery calcium can sometimes help resolve a treatment decision in an otherwise uncertain patient.
What a cardiovascular risk assessment may include
- Blood pressure
- Smoking and nicotine exposure
- Family history of premature cardiovascular disease
- Standard lipid profile
- ApoB selectively
- Lipoprotein(a) at least once in adulthood
- Glucose, HbA1c and diabetes status
- Kidney-disease context
- Weight, waist and metabolic health
- Coronary artery calcium only where treatment uncertainty makes it useful
Start with established risk factors
Most risk estimation comes from information available without advanced testing: age, blood pressure, smoking, diabetes, cholesterol and relevant medical history. These factors have the strongest evidence and should be addressed before adding more complex markers.
When ApoB and Lp(a) add information
ApoB can refine risk when LDL cholesterol may not reflect atherogenic particle number, especially in cardiometabolic disease. Lp(a) is largely inherited and current guidance supports measuring it at least once in adulthood. Neither result should be interpreted in isolation.
When coronary artery calcium can help
Coronary artery calcium is not routine screening for everyone. In selected adults with borderline or intermediate risk where the decision about preventive drug treatment remains uncertain, a calcium score can sometimes reclassify risk and make that decision clearer. Age, symptoms and clinical context matter.
What changes after risk is defined
The purpose of assessment is action. Depending on the result, management may include blood-pressure treatment, smoking cessation, improved metabolic health, exercise and nutrition, and lipid-lowering medication where indicated. The intensity of treatment should match absolute risk rather than one laboratory value.
Common questions
Answers before you book.
Can I have heart risk with normal cholesterol?
Yes. Blood pressure, smoking, diabetes, kidney disease, family history and elevated Lp(a) can increase risk even when standard cholesterol values are not striking. Risk is the combined picture.
Should everyone get a coronary calcium score?
No. It is most useful when a prevention decision remains genuinely uncertain after standard risk assessment. It is not a routine screening test for every healthy adult.
What does Lp(a) add?
Lp(a) identifies an inherited source of cardiovascular risk that is usually invisible on a standard lipid panel. A high result can justify more intensive management of modifiable risk factors.
How often should cardiovascular risk be reassessed?
Frequency depends on age, baseline risk and whether treatment is changing. Higher-risk patients and those starting therapy need closer review, while low-risk stable patients can be reassessed less often.
