Preventive Cardiology: Knowing and Managing Your Risk
A great deal of cardiovascular disease is influenced by factors that can be identified and modified long before symptoms appear. Prevention is less dramatic than intervention, but across a population it prevents far more heart attacks than any procedure.
The major modifiable risk factors
High blood pressure, raised LDL cholesterol, diabetes, smoking, excess weight, physical inactivity and excessive alcohol are the principal modifiable contributors.
Each is measurable, and each responds to treatment. Their effects compound — someone with several factors carries considerably more risk than the sum of each considered alone.
Factors that cannot be changed
Age, sex, family history and ethnicity also influence risk. South Asians tend to develop coronary artery disease earlier and at lower body weights than many other populations, which is why waiting until later life to begin screening is not advisable in this group.
These factors cannot be altered, but knowing them changes how aggressively the modifiable ones should be managed.
When to start checking
Rather than waiting for symptoms, a reasonable approach is to know your blood pressure, cholesterol profile and blood sugar from early adulthood, particularly where there is a family history of heart disease or diabetes.
The frequency of subsequent checks depends on those initial results and your overall risk profile. Your doctor can advise on what is appropriate for you.
What actually helps
Regular physical activity — sustained and moderate rather than occasional and intense — is among the most effective interventions. A diet weighted toward whole grains, vegetables, fruit, pulses and nuts, with less fried, processed and salty food, supports blood pressure, cholesterol and weight simultaneously.
Stopping smoking produces measurable reduction in cardiovascular risk relatively quickly. Adequate sleep and managing chronic stress matter more than they are usually given credit for.
Why prevention deserves attention
Interventional cardiology can restore blood flow to a blocked artery, and it saves lives daily. But it addresses a problem that has already developed. Risk-factor management works on the process that produces the blockage in the first place.
The two are complementary, not alternatives. The best outcome is the heart attack that never happens.
Frequently asked questions
At what age should I have my first heart check?
This varies with individual and family history. Many clinicians suggest knowing your blood pressure, cholesterol and blood sugar from early adulthood, particularly where there is a family history.
Is a treadmill test needed for everyone?
No. It is used where there is a specific clinical question. Routine testing in people without symptoms or risk factors is not generally recommended.
Does family history mean heart disease is inevitable?
No. It raises risk and lowers the threshold for careful management, but the modifiable factors remain the main determinants.
How much exercise is recommended?
General guidance suggests regular moderate activity across the week, but the right amount depends on your health and any existing conditions. Ask your doctor before starting a new programme.
