Cardiovascular disease (CVD) is the leading cause of death worldwide, responsible for nearly one in three deaths globally. It refers to a range of disorders affecting the heart and blood vessels, from coronary artery disease to stroke. Understanding what cardiovascular disease is, what causes it, and how it can be prevented is essential for reducing its enormous burden.
According to the World Health Organization, CVD accounted for 19.8 million deaths in 2022, with 85% of those deaths resulting from heart attacks and strokes. The condition affects people of all ages, genders, and backgrounds, though the risk increases with age and certain lifestyle factors. Many forms of CVD develop silently over years, making awareness and early detection critical.
This article provides a comprehensive, fact-based overview of cardiovascular disease—its definition, causes, symptoms, types, treatment, and prevention—based on authoritative sources such as the World Health Organization, the NHS, and the American Heart Association.
What is cardiovascular disease?
A group of disorders of the heart and blood vessels, including coronary heart disease, stroke, and peripheral artery disease.
Primarily atherosclerosis (plaque buildup), but also hypertension, high cholesterol, smoking, diabetes, and genetic factors.
Chest pain, shortness of breath, fatigue, palpitations, leg pain, and in severe cases heart attack or stroke.
Lifestyle changes (diet, exercise, no smoking), medications (statins, antihypertensives), and procedures (angioplasty, bypass surgery).
Key insights
- Cardiovascular diseases are the leading cause of death globally, accounting for over 18 million deaths each year (WHO).
- Many CVDs are preventable through addressing modifiable risk factors like tobacco use, unhealthy diet, physical inactivity, and harmful use of alcohol.
- Early detection and management of CVDs are critical; symptoms may be subtle or absent until a serious event occurs.
- The British Heart Foundation estimates that around 7.6 million people in the UK live with heart and circulatory diseases.
- CVD is an umbrella term for conditions affecting the heart and blood vessels.
- Global impact: 32% of all deaths worldwide, according to the WHO 2025 fact sheet.

What causes cardiovascular disease?
Most cases of CVD develop as a complication of atherosclerosis—a condition in which fatty deposits (plaques) build up inside the arteries, narrowing them and restricting blood flow. This process can begin early in life and progress silently for decades.
Primary causes and underlying mechanisms
Several conditions directly contribute to atherosclerosis and CVD: high blood pressure (hypertension), high cholesterol (dyslipidemia), diabetes, and chronic inflammation. Viral infections, structural abnormalities present at birth, and autoimmune conditions can also lead to CVD. According to WHO research, broader forces such as globalization, urbanization, population aging, poverty, stress, and hereditary factors drive the disease at a population level.
The INTERHEART study, covering 52 countries, identified nine modifiable risk factors that together account for 90% of the risk of a first heart attack. Smoking alone accounts for 36% of population-attributable risk. The other factors include dyslipidemia, hypertension, diabetes, abdominal obesity, psychosocial factors, low fruit and vegetable intake, regular alcohol consumption, and physical inactivity.
Modifiable risk factors
Beyond the INTERHEART factors, additional modifiable risks include tobacco use (including vaping), excess weight and obesity, a diet high in sodium, sugar, and fat, harmful alcohol use, air pollution, misuse of prescription or recreational drugs, chronic inflammatory or autoimmune conditions, and chronic kidney disease.
Non-modifiable risk factors
Some risk factors cannot be changed: family history of heart disease, genetic predisposition and familial hypercholesterolemia, older age, sex and gender differences, race and ethnicity, and pregnancy-related conditions such as preeclampsia or gestational diabetes. Research published in JAMA indicates that lifetime CVD risk exceeds 50% for both men and women, and even among those with few risk factors the risk remains above 30%.
What are the symptoms of cardiovascular disease?
Symptoms vary depending on the type of CVD and may be subtle or absent until a serious event occurs. Common symptoms include chest pain or discomfort (angina), shortness of breath, exhaustion and fatigue, palpitations (irregular heartbeat), and leg pain or cramping (particularly in peripheral artery disease). In women, symptoms can differ—for example, nausea, jaw pain, or extreme fatigue may accompany a heart attack more often than in men.
Chest pain, especially when accompanied by shortness of breath, sweating, or pain spreading to the arm or jaw, may indicate a heart attack and requires immediate emergency care. Sudden weakness or numbness on one side of the body, trouble speaking, or severe headache can signal a stroke.
What are the main types of cardiovascular disease?
CVD is not a single condition but a group of disorders. The most common types include:
- Coronary artery disease (CAD) – also called coronary heart disease, affecting the arteries that supply the heart muscle.
- Cerebrovascular disease – affecting blood vessels in the brain, including stroke.
- Rheumatic heart disease – damage to heart valves from rheumatic fever.
- Angina – chest pain caused by reduced blood flow to the heart.
- Heart failure – when the heart cannot pump enough blood to meet the body’s needs.
- Congenital heart disease – structural heart problems present from birth.
- Myocarditis – inflammatory disease of the heart muscle.
Other important conditions include peripheral artery disease, arrhythmias, and valvular heart disease.
How has our understanding of cardiovascular disease evolved over time?
- Ancient times: Recognition of heart attacks and strokes existed, but the mechanisms were not understood.
- 1912: James Herrick first described acute myocardial infarction (heart attack).
- 1950s–1960s: The Framingham Heart Study identified key risk factors—cholesterol, hypertension, and smoking.
- 1970s: Introduction of coronary artery bypass surgery.
- 1980s: Development of statins to lower cholesterol.
- 2000s: Increased focus on prevention and public health campaigns.
- 2020s: Advances in genetic testing and personalized medicine for CVD.
What do we know and what remains uncertain about cardiovascular disease?
| Established information | Information that remains unclear |
|---|---|
| Atherosclerosis is the underlying cause of most CVD. | Exact role of genetics versus environment in individual cases. |
| Smoking, hypertension, diabetes, and high cholesterol significantly increase risk. | Optimal prevention strategies for different populations (e.g., aspirin use). |
| Regular exercise and a healthy diet reduce risk. | Long-term effects of new treatments and medications are still being studied. |
Why does cardiovascular disease remain a major health challenge?
Despite major advances in treatment and prevention, CVD remains the world’s biggest killer. Socioeconomic factors, unequal healthcare access, and lifestyle changes—such as sedentary jobs and the widespread availability of processed foods—continue to drive prevalence. Public health initiatives like the UK’s NHS Health Check and the WHO’s “25 by 25” goal aim to reduce premature CVD deaths. Emerging research into inflammation, the gut microbiome, and dietary patterns offers hope for more targeted therapies, but implementing proven prevention strategies at scale remains difficult.

Early action remains the most powerful tool against the world’s leading cause of death.
Frequently asked questions about cardiovascular disease
What is cardiovascular disease journal?
There are many medical journals focusing on cardiovascular disease, such as the Journal of the American College of Cardiology (JACC), Circulation, and the European Heart Journal. They publish research on causes, diagnosis, treatment, and prevention. You can find them through PubMed or university libraries.
Where can I download a PDF list of cardiovascular diseases?
Health organizations like the WHO and NHS provide PDF fact sheets. The WHO fact sheet on CVDs includes a list of major types. The British Heart Foundation also offers downloadable resources on specific conditions.
How does cardiovascular disease affect the body?
CVD impairs heart and blood vessel function. Coronary artery disease reduces blood flow to the heart, causing chest pain or heart attack. Stroke cuts off blood supply to part of the brain. Peripheral artery disease causes leg pain and poor circulation. Over time, CVD can damage organs due to inadequate blood supply.
What are the early signs of cardiovascular disease?
Early signs can include chest discomfort, shortness of breath, fatigue, palpitations, and leg pain. Many people have no symptoms until a heart attack or stroke occurs. Regular check-ups are important for detecting risk factors like high blood pressure and high cholesterol.
What is the difference between heart disease and cardiovascular disease?
Cardiovascular disease is a broader term that includes all conditions affecting the heart and blood vessels. Heart disease usually refers specifically to conditions that affect the heart, such as coronary artery disease and heart failure. All heart diseases are CVD, but not all CVD is heart disease (e.g., stroke).
How can cardiovascular disease be prevented naturally?
Natural prevention focuses on lifestyle: eating a diet rich in fruits, vegetables, and whole grains; maintaining a healthy weight; exercising regularly; not smoking; limiting alcohol; managing stress; and monitoring blood pressure, cholesterol, and blood sugar. These measures can reduce risk by up to 80%.
Do cardiovascular disease symptoms differ in women?
Yes. Women may experience less typical symptoms during a heart attack, such as nausea, indigestion, jaw pain, or extreme fatigue. They are also more likely than men to have microvascular disease (affecting small arteries). Awareness of these differences can improve early recognition and treatment.
What is the most common type of cardiovascular disease?
Coronary artery disease (also called coronary heart disease) is the most common type of cardiovascular disease. It affects the arteries that supply blood to the heart muscle and can lead to angina, heart attacks, and heart failure. It is a leading cause of death worldwide.
What are the global statistics for cardiovascular disease?
In 2022, CVD caused 19.8 million deaths (32% of all deaths). 85% were due to heart attack or stroke. Over three-quarters of these deaths occur in low- and middle-income countries. One-third of CVD deaths are in people under 70. Lifetime risk exceeds 50% for both men and women.
