Cardiovascular risk factors
Understand them to protect your heart and live longer.
Cardiovascular disease does not appear suddenly. In most cases, it results from a process that unfolds slowly over many years.
Atherosclerosis, which underlies many cardiovascular conditions, can begin early and progress silently for a long time before symptoms appear.
This is why effective prevention means more than treating an existing disease. Above all, it means identifying people at risk early and taking action before the disease develops.
Knowing your cardiovascular risk factors means gaining a better understanding of your future cardiovascular health and, above all, the opportunity to change it.
What are cardiovascular risk factors?
Cardiovascular risk factors are individual characteristics, clinical conditions or lifestyle habits associated with a greater likelihood of developing heart or blood vessel disease over time.
Having a risk factor does not necessarily mean you will develop cardiovascular disease.
It does, however, mean that your likelihood is higher than that of someone without that factor. This is precisely where prevention comes in: recognizing risk before it becomes disease.
Not all risk factors are the same
Nonmodifiable factors
These are characteristics we cannot change directly, but which must be considered in a comprehensive assessment:
Age
Genetics
Family history of cardiovascular disease
Understanding them matters because they can change the significance of other risk factors.
Modifiable factors
These are conditions that can be addressed through lifestyle changes and, when necessary, treatment:
Hypertension
High cholesterol
Smoking
Diabetes
Overweight and obesity
Lifestyle is part of prevention
Today, cardiovascular prevention also recognizes the essential role of lifestyle. Physical inactivity, an unbalanced diet and other unhealthy habits can contribute over time to the development of major risk factors and the progression of cardiovascular damage. Conversely, regular physical activity, a balanced diet, weight management and smoking cessation are essential tools for prevention.
A fundamental principle of modern cardiovascular prevention is that the same measurement can mean different things in different people.
A particular cholesterol level, for example, should not be interpreted in isolation, but alongside age, blood pressure, diabetes, smoking, family history and the other characteristics of that individual.
The question should therefore be more than:
“What is my cholesterol level?”
The more important question is:
“What is my overall cardiovascular risk?”
How is cardiovascular risk calculated?
Risk factors do not act independently.
When several factors are present at the same time, overall cardiovascular risk increases. Modern prevention therefore considers overall cardiovascular risk, integrating the person's different characteristics rather than focusing on a single measurement.
Blood pressure + Cholesterol + Smoking + Diabetes + Weight + Age + Genetics + Lifestyle
Overall cardiovascular risk
Personalized prevention
Cardiovascular prevention and longevity
Protecting your heart also means increasing your chances of living longer in good health. An international study of more than 2 million people from 39 countries across six continents showed that, after age 50, the absence of the five main risk factors - hypertension, hyperlipidemia, overweight/obesity, smoking and diabetes - was associated with 14.5 additional years of life in women and 11.8 in men.
Cardiovascular prevention is about more than adding years to life. It is about trying to add life to those years.
Understanding risk to decide how to act
Knowing the main cardiovascular risk factors is the first step, but treating them as a simple checklist is not enough. A table of cardiovascular risk factors can provide useful guidance; however, an assessment must determine how much each factor matters for the individual and how it interacts with the others. Cardiovascular risk calculation, as part of a comprehensive clinical assessment, helps establish realistic priorities and a personalized prevention plan. Addressing modifiable factors while accounting for nonmodifiable ones turns an understanding of risk into practical choices for heart health and a longer, healthier life.
Frequently asked questions about cardiovascular risk factors
What are the main cardiovascular risk factors?
The main cardiovascular risk factors include age, genetics and family history, which cannot be changed, as well as hypertension, high cholesterol, smoking, diabetes, overweight and obesity. Physical inactivity and an unbalanced diet also contribute to the overall risk profile.
What are the five most studied cardiovascular risk factors?
The five cardiovascular risk factors commonly referred to are hypertension, high cholesterol or other blood lipid abnormalities, overweight or obesity, smoking and diabetes. These factors are modifiable, and managing them can have a substantial impact on cardiovascular health and longevity.
What is the difference between modifiable and nonmodifiable cardiovascular risk factors?
Nonmodifiable cardiovascular risk factors, such as age, genetics and family history, are part of a person's background and must be considered in the assessment. Modifiable cardiovascular risk factors, such as high blood pressure, cholesterol, smoking, diabetes and excess weight, can be corrected or controlled through lifestyle changes and, when indicated, treatment.
How is cardiovascular risk calculated?
Cardiovascular risk calculation is not a simple sum of individual factors. It uses validated tools that integrate data such as age, sex, smoking status, blood pressure and cholesterol levels. The choice of tool also depends on age, existing disease and clinical context. A physician must interpret the result alongside personal and family history and any additional risk factors.
Is there a formula for calculating cardiovascular risk?
There is no single formula that suits everyone. Among the most reliable, scientifically validated algorithms for calculating individual cardiovascular risk are SCORE2 and SCORE2-OP (Systematic Coronary Risk Evaluation 2), developed by the SCORE2 Working Group in collaboration with the European Society of Cardiology.
The tool was developed using epidemiological data from more than 677,000 participants in 45 study cohorts across 13 European countries. The resulting value is a probability estimate, not a diagnosis. It should therefore not be interpreted in isolation or used to change treatment without medical advice.
Is a table of cardiovascular risk factors enough to determine my risk?
No. A table can help identify common factors, but it cannot measure overall cardiovascular risk on its own. The same blood pressure or cholesterol level can carry different significance depending on age, smoking, diabetes, family history and other clinical conditions.
Are there new cardiovascular risk factors?
Alongside traditional factors, research is investigating additional conditions and markers that may help refine risk assessment. Chronic kidney disease, inflammatory conditions, psychosocial factors and certain findings from specific tests may be important in selected individuals. They do not replace the main cardiovascular risk factors, however, and must be evaluated in the individual's clinical context.
