How to Lower Your Cardiovascular Risk: What Actually Works
Heart attack and stroke risk is driven by a few modifiable factors. What genuinely lowers it per the ESC — blood pressure, cholesterol, smoking, blood sugar, weight, activity — and how to find your risk.
Contents
Heart attack and stroke risk isn't a lottery or a matter of luck with your genes. It's mostly set by a short list of modifiable factors, and a few of them do almost all the work. The good news: you don't need to make them perfect — even partial improvements in blood pressure, cholesterol, or quitting smoking move your 10-year risk down meaningfully.
First — find your number
Before changing anything, it helps to know where you stand. European cardiologists (ESC) estimate 10-year risk with the SCORE2 scale: it takes age, sex, smoking, systolic blood pressure and cholesterol, and returns your chance of a heart attack or stroke over the next 10 years.

The number matters because it decides how aggressively to push each factor: at low risk, lifestyle usually suffices; at high risk, medication is added.
What actually lowers risk
| Factor | Why it matters | Target |
|---|---|---|
| Smoking | One of the largest avoidable factors; risk drops within the first year of quitting | Full stop |
| Blood pressure | The main driver of stroke; even a 10 mmHg drop cuts risk noticeably | around 120–129/80 |
| LDL cholesterol | A causal factor in atherosclerosis: lower and longer is better | Depends on overall risk |
| Blood sugar / diabetes | Diabetes sharply raises risk; glucose and weight control matter | HbA1c in target range |
| Weight and waist | Abdominal fat links to blood pressure, sugar and lipids | Waist < half your height |
| Movement | 150 minutes of moderate activity a week lowers risk regardless of weight | 150 min/wk + strength |
Note that LDL cholesterol has no single "normal for everyone" — the target is lower the higher your overall risk. So a lab number is best read alongside your SCORE2 result, not on its own.

Blood pressure — the most underrated lever
High blood pressure doesn't hurt for years, so it's easy to ignore — yet it's the main driver of stroke. The good news: it responds to both lifestyle (salt, weight, movement, alcohol) and medication. Start by simply knowing your numbers and their category.

What you can't change — and why it isn't a verdict
Age, sex and genetics feed the calculation but can't be influenced. Lipoprotein(a) is a separate case: a genetically set factor that ordinary measures barely move. That's not a reason to give up — it's a reason to hold the changeable factors tighter: blood pressure, LDL, smoking, weight.

When medication is needed
Lifestyle is the foundation, but not always enough. At high calculated risk, high LDL, diabetes, or after an event, a doctor adds medication — most often statins. That's not "giving up" but reinforcing: statins lower LDL and event risk on solid evidence, and the myths around them are mostly overblown.

FAQ
What affects heart attack and stroke risk the most?+
A short list of modifiable factors: smoking, blood pressure, LDL cholesterol, blood sugar (diabetes), excess weight and low physical activity. In risk models like SCORE2 these — together with age and sex — set your 10-year risk. Age, sex and genetics (e.g. Lp(a)) can't be changed, which makes the changeable ones matter more.
How do I find my cardiovascular risk?+
European cardiologists (ESC) use the SCORE2 scale: it estimates your 10-year chance of a heart attack or stroke from age, sex, smoking, blood pressure and cholesterol. You can run it with our CVD risk calculator, using real numbers from a blood-pressure monitor and a blood test.
Does aspirin help for prevention?+
For primary prevention (no prior heart attack or stroke), routine aspirin is no longer broadly recommended: bleeding risk often outweighs the benefit. It's an individual decision for your doctor. After an event it's a different story — aspirin is usually prescribed there.
Can I lower my risk without medication?+
Largely yes, especially at low-to-moderate risk: quitting smoking, controlling blood pressure and weight, moving and eating well do most of the work. But with high LDL cholesterol, diabetes or a high calculated risk, lifestyle is combined with medication (statins and others) — not replaced by it.
