Cardiovascular disease refers to a group of conditions affecting the heart and blood vessels. It includes conditions involving the coronary arteries, heart rhythm, heart muscle, heart valves, and blood vessels throughout the body.
Important: This article is for general information only and is not a substitute for professional medical advice, diagnosis, or treatment.
Terms like “cardiovascular disease,” “heart disease,” and “coronary artery disease” often get used interchangeably, but they’re not quite the same thing. The CDC describes heart disease as a group of conditions affecting the heart, with coronary artery disease as the most common individual type in the U.S. Cardiovascular disease is the broader umbrella that includes heart disease plus conditions affecting blood vessels elsewhere in the body, including the brain.
This guide covers the major types of cardiovascular disease, what causes them, who’s at risk, how they’re diagnosed and treated, and practical, evidence-based ways to lower your risk.
What Is Cardiovascular Disease?
Cardiovascular disease isn’t one diagnosis — it’s a category that covers dozens of specific conditions affecting how blood moves through your body. What they share is a connection to the heart, the blood vessels, or both.
Cardiovascular Disease vs. Heart Disease
These terms overlap heavily but aren’t identical:
- Heart disease generally refers to conditions affecting the heart itself — its muscle, valves, rhythm, or the coronary arteries that supply it.
- Cardiovascular disease is broader. It includes heart disease plus conditions affecting blood vessels throughout the rest of the body, such as stroke and peripheral artery disease.
A simple way to picture the hierarchy:
Cardiovascular Disease → includes → Heart diseases (coronary artery disease, heart failure, arrhythmias, valve disease) and Blood vessel diseases (stroke, peripheral artery disease, aortic disease)
Our guide to what heart disease is covers the heart-specific conditions in more depth.
What Are the Different Types of Cardiovascular Disease?
Coronary Artery Disease
Coronary artery disease (CAD) is the most common type of cardiovascular disease in the United States. It develops when plaque — made of cholesterol and other substances — builds up inside the arteries that supply blood to the heart. As that buildup narrows the arteries, blood flow to the heart muscle decreases, which can cause angina (chest pain from reduced blood flow) and, if an artery becomes suddenly blocked, a heart attack.
Heart Failure
Despite the alarming name, heart failure doesn’t mean the heart has stopped. It means the heart can’t pump or fill with blood as efficiently as the body needs. The CDC estimates that nearly 6.7 million U.S. adults have heart failure, and it’s most often caused by another condition that has damaged the heart over time — commonly coronary artery disease or long-standing high blood pressure.
Arrhythmias
An arrhythmia is an abnormal heart rhythm — the heart beats too fast, too slow, or irregularly. Common types include:
- Atrial fibrillation (AFib) — the most common type of treated arrhythmia, in which the heart’s upper chambers beat out of coordination with the lower chambers
- Bradycardia — an abnormally slow heart rate
- Tachycardia — an abnormally fast heart rate
Heart Valve Disease
The heart has four valves that keep blood flowing in the right direction. Valve disease occurs when a valve doesn’t open or close properly — either narrowing (stenosis), which restricts blood flow, or leaking (regurgitation), which lets blood flow backward. Severity ranges widely, from conditions that just need monitoring to those requiring surgical repair.
Cardiomyopathy
Cardiomyopathy refers to diseases of the heart muscle itself, which can make it harder for the heart to pump blood effectively. It can result from genetics, prior heart damage, certain infections, or other causes, and severity varies considerably.
Congenital Heart Disease
Some cardiovascular conditions are present from birth, ranging from minor structural differences that need no treatment to complex defects requiring early surgical intervention. Advances in detection and treatment mean many people with congenital heart disease now live long, active lives.
Peripheral Artery Disease
Peripheral artery disease (PAD) affects arteries outside the heart, most often in the legs. Like coronary artery disease, it’s usually caused by plaque buildup that narrows the arteries — in this case, reducing blood flow to the limbs rather than the heart. It shares many of the same risk factors as coronary artery disease and often occurs alongside it.
Stroke and Cerebrovascular Disease
A stroke happens when blood flow to part of the brain is blocked or a blood vessel in the brain bursts. It’s technically a disease of the brain rather than the heart, but it’s included under the cardiovascular disease umbrella because it results from the same underlying blood vessel disease — atherosclerosis and clot formation — that drives heart attacks. This is exactly why blood pressure, cholesterol, and diabetes management matter for stroke risk just as much as for heart disease risk.
What Causes Cardiovascular Disease?
Cardiovascular disease doesn’t have a single cause — the mechanism varies somewhat by condition. That said, several underlying processes show up repeatedly across different types:
- Plaque buildup narrowing the arteries (atherosclerosis)
- Inflammation within blood vessel walls
- Blood clot formation
- High blood pressure sustained over time
- Abnormal cholesterol levels
- Elevated blood glucose and diabetes
- Tobacco exposure
For coronary artery disease specifically, the CDC explains that plaque made of cholesterol and other substances builds up inside the coronary arteries, and this buildup — atherosclerosis — narrows the arteries and can reduce blood flow to the heart. The same basic process drives peripheral artery disease and many strokes, just in different blood vessels.
It’s worth being precise here: not every form of cardiovascular disease shares this exact mechanism. Arrhythmias, for example, often stem from electrical signaling problems rather than blocked arteries, and congenital heart disease results from how the heart developed before birth.
What Increases Your Risk of Cardiovascular Disease?
Modifiable Risk Factors
Factors you can often change or manage:
- High blood pressure
- High LDL cholesterol
- Smoking and tobacco use
- Physical inactivity
- An unhealthy dietary pattern
- Excess body weight
- Diabetes and elevated blood sugar
- Excess alcohol use
- Poor sleep
The CDC identifies high blood pressure, high cholesterol, and smoking as key heart disease risk factors, alongside diabetes, obesity, unhealthy diet, physical inactivity, and excessive alcohol use.
Nonmodifiable Risk Factors
Factors that can’t be changed:
- Age
- Family history of early heart disease
- Genetics
- Certain congenital conditions
Why Multiple Risk Factors Matter
Cardiovascular risk isn’t determined by any single measurement in isolation — it’s shaped by the combination of factors present at once. Someone with mildly elevated blood pressure and no other risk factors faces a different overall risk than someone with the same blood pressure reading who also smokes and has diabetes. This is exactly why healthcare providers increasingly look at combined cardiovascular risk assessment rather than treating each number separately, which we cover in more detail below.
How Does High Blood Pressure Affect Cardiovascular Health?
High blood pressure is one of the most significant, and most common, drivers of cardiovascular disease — largely because it’s also one of the easiest to miss. It typically causes no symptoms, so many people don’t know they have it until it’s measured.
The 2025 AHA/ACC hypertension guideline describes high blood pressure as a major modifiable risk factor for cardiovascular disease, including coronary artery disease, heart failure, atrial fibrillation, and stroke. Persistently elevated pressure strains blood vessel walls and adds to the heart’s workload with every beat — over years, that combination contributes to atherosclerosis, weakens the heart muscle, and raises the risk of kidney disease as well.
Regular monitoring is what actually catches this early, since symptoms usually won’t. Our guides to blood pressure and heart health and how to lower blood pressure safely cover this connection and practical management in more depth.
How Does Cholesterol Affect Cardiovascular Disease?
Cholesterol travels through your bloodstream in a few different forms:
- LDL cholesterol can contribute to plaque buildup within artery walls
- HDL cholesterol helps clear cholesterol away from the arteries
- Triglycerides are another blood fat linked to cardiovascular risk when elevated
The 2026 ACC/AHA/Multisociety Dyslipidemia Guideline emphasizes managing cardiovascular risk factors across the lifespan and identifies elevated atherogenic lipoproteins — including LDL — as an important driver of future atherosclerotic cardiovascular disease risk. The relationship is largely about duration: the longer LDL cholesterol stays elevated, the more it contributes to plaque buildup over time, which is part of why the guideline emphasizes earlier testing and management rather than waiting until midlife. Our guides to high cholesterol and cholesterol and heart health go into more detail.
What Are the Symptoms of Cardiovascular Disease?
Symptoms vary substantially depending on the specific condition — and importantly, some cardiovascular disease produces no symptoms at all, especially in earlier stages.
Common Symptoms
Across various types of cardiovascular disease, possible symptoms include:
- Chest pain or pressure
- Shortness of breath
- Unusual fatigue
- Dizziness or lightheadedness
- Palpitations
- Swelling in the legs, ankles, or feet
- Reduced exercise tolerance
This isn’t a diagnostic checklist — having one or more of these doesn’t confirm cardiovascular disease, and a healthcare provider is needed to sort out what’s actually going on. Our guides to what causes dizziness, shortness of breath, and what causes fatigue cover these symptoms and their many other possible causes.
Symptoms by Condition
Coronary artery disease may cause chest pain or pressure (angina), particularly during exertion, along with shortness of breath.
Heart failure commonly causes shortness of breath, fatigue, and swelling in the legs, ankles, feet, or abdomen as fluid builds up.
Arrhythmias often cause palpitations — a fluttering, racing, or pounding sensation in the chest — along with dizziness or fainting in some cases.
Can Cardiovascular Disease Have No Symptoms?
Yes, and this is one of the most important things to understand about cardiovascular disease. The CDC notes that heart disease can sometimes remain silent until symptoms of an event — a heart attack, heart failure, or arrhythmia — appear for the first time. This is exactly why regular blood pressure and cholesterol checks matter even when you feel completely fine.
When Cardiovascular Symptoms May Be an Emergency
Some symptoms require immediate action rather than a wait-and-see approach. This section is worth reading closely even if you feel generally healthy.
Heart Attack Warning Signs
Possible symptoms include:
- Chest discomfort or pressure
- Shortness of breath, with or without chest discomfort
- Discomfort spreading to the arms, shoulder, back, neck, or jaw
- Nausea or a cold sweat
- Lightheadedness
Symptoms vary between individuals, and women in particular are somewhat more likely to experience symptoms beyond classic chest pain, such as shortness of breath, back or jaw discomfort, and nausea, according to the CDC’s guidance on women and heart disease. Our guides to heart attack symptoms and chest pain cover these in more detail.
Stroke Warning Signs: Act F.A.S.T.
The CDC recommends the F.A.S.T. test to quickly identify a possible stroke:
- F — Face drooping. Ask the person to smile. Does one side droop?
- A — Arm weakness. Ask the person to raise both arms. Does one arm drift downward?
- S — Speech difficulty. Ask the person to repeat a simple sentence. Is speech slurred or strange?
- T — Time to call 911. If you see any of these signs, call 911 immediately, even if symptoms go away.
Additional stroke symptoms can include sudden confusion, trouble seeing, sudden severe headache, or sudden trouble walking or loss of balance.
If you or someone near you has any of these symptoms, call 911 right away. Don’t wait to see if they pass, and don’t attempt to drive to the hospital yourself — treatments for both heart attack and stroke work best when given quickly.
How Is Cardiovascular Disease Diagnosed?
Diagnosis depends heavily on the specific condition a provider suspects, based on your symptoms, history, and risk factors. Not everyone needs every test — a provider determines which evaluation makes sense for your situation. Tests may include:
- Blood pressure measurement — repeated readings over time
- Cholesterol and blood tests — a lipid panel measuring LDL, HDL, and triglycerides
- Blood glucose or A1C — to assess diabetes or prediabetes
- Electrocardiogram (ECG/EKG) — checks the heart’s electrical activity
- Echocardiogram — an ultrasound that visualizes the heart’s structure and function
- Stress testing — evaluates how the heart performs under exertion
- Coronary CT or other imaging — visualizes the coronary arteries directly
- Cardiac catheterization — a more invasive procedure used in specific situations
How Is Your Risk of Cardiovascular Disease Estimated?
Beyond diagnosing a specific condition, healthcare professionals also estimate overall cardiovascular risk — essentially, the likelihood of a future cardiovascular event based on your combined risk factors. This typically draws on:
- Age
- Blood pressure
- Cholesterol
- Diabetes status
- Smoking status
- Kidney function
- Existing cardiovascular disease
The 2025 AHA/ACC blood pressure guideline incorporates the PREVENT equations — a tool that combines cardiovascular, kidney, and metabolic health measures — to estimate 10-year cardiovascular risk and help guide treatment decisions, including when to start blood pressure medication.
This kind of risk assessment is meant to inform a conversation with your provider, not to replace one. The PREVENT calculator is a clinical tool intended for use by healthcare professionals as part of an individualized evaluation, not something to self-diagnose from.
Can Cardiovascular Disease Be Prevented?
Many cases of cardiovascular disease can have their risk meaningfully reduced, even though prevention can’t be guaranteed for everyone — especially when nonmodifiable factors like genetics play a strong role. The CDC recommends healthy habits and management of conditions like blood pressure, cholesterol, and blood sugar to help reduce heart disease risk.
Eat a Heart-Healthy Diet
Build meals around vegetables and fruits, whole grains, legumes, nuts and seeds, fiber-rich foods, and healthy fats, while limiting sodium and highly processed foods. See our guides to heart-healthy foods, healthy fats, omega-3 fatty acids, and the Mediterranean diet.
Exercise Regularly
Combine aerobic activity with strength training, and reduce sedentary time where you can. Our guide to exercise and heart health covers how much activity you actually need.
Don’t Smoke
Quitting lowers cardiovascular risk regardless of how long you’ve smoked.
Manage Blood Pressure, Cholesterol, and Blood Sugar
Regular monitoring, lifestyle changes, and medication when appropriate all play a role. Our guides to what diabetes is and how to prevent diabetes cover the blood sugar side of this equation.
Maintain a Healthy Weight
Sustainable habits matter more than rapid weight loss. See our guide to weight management.
Get Adequate Sleep and Limit Alcohol
Both affect blood pressure and other cardiovascular risk factors over time. See our guide to improving sleep.
Keep Up With Preventive Healthcare
Routine visits are what catch silent risk factors before they cause damage.
For a full, practical breakdown of these steps, see our dedicated guide: How to Prevent Heart Disease: 10 Evidence-Based Ways to Protect Your Heart.
How Is Cardiovascular Disease Treated?
Treatment depends entirely on the specific condition involved — there’s no single treatment plan for “cardiovascular disease” as a whole.
Lifestyle Changes
For nearly every cardiovascular condition, heart-healthy eating, regular activity, not smoking, and managing related conditions form the foundation of treatment, often alongside other approaches below.
Medications
Depending on the condition, medications may target:
- Blood pressure
- Cholesterol
- Blood clotting (antiplatelet or anticoagulant medications)
- Heart failure symptoms and progression
- Abnormal heart rhythms
Procedures and Surgery
Some conditions require more direct intervention, including:
- Angioplasty and stenting to open blocked arteries
- Bypass surgery to reroute blood flow around blockages
- Valve repair or replacement procedures
- Ablation to correct certain arrhythmias
- Pacemakers or other implantable devices
Cardiac Rehabilitation
For people recovering from a heart attack, heart surgery, or certain other cardiovascular events, cardiac rehabilitation offers supervised exercise combined with broader lifestyle guidance — a structured way to rebuild activity tolerance safely rather than figuring out a safe starting point alone.
Who Can Develop Cardiovascular Disease?
Cardiovascular disease can affect people across age groups, and it’s not determined by sex or age alone.
In Women
Cardiovascular disease affects women at every age, and symptom patterns can differ somewhat from men’s — notably, women are more likely to experience heart attack symptoms beyond classic chest pain.
In Men
Men tend to develop coronary artery disease somewhat earlier in life on average, though individual risk varies enormously based on the full combination of risk factors present.
In Older Adults
Cardiovascular risk generally rises with age, as decades of exposure to risk factors accumulate and arteries naturally stiffen over time.
In Younger Adults
Cardiovascular disease isn’t exclusively a condition of older age. Risk factors like family history, congenital conditions, diabetes, and lifestyle habits can affect risk at any age, which is exactly why prevention habits matter well before midlife.
Family History and Genetic Risk
A strong family history — particularly a parent or sibling diagnosed with heart disease at an early age — raises individual risk and may point toward an inherited condition. It’s not, on its own, a guarantee of future disease, but it’s a good reason to discuss earlier or more frequent screening with a healthcare provider.
When Should You Talk to a Healthcare Professional?
Consider scheduling an evaluation if you have:
- Persistently elevated blood pressure
- Abnormal cholesterol
- Diabetes or prediabetes
- New or unexplained palpitations
- Unusual shortness of breath
- Reduced exercise tolerance
- Recurrent chest discomfort
- A strong family history of cardiovascular disease
- Questions about your overall cardiovascular risk
When to Seek Emergency Care
Treat the following as a medical emergency and call 911:
- New, severe chest pressure or discomfort
- Severe shortness of breath
- Any signs of stroke (use the F.A.S.T. test above)
- Fainting accompanied by other concerning symptoms
- Any other sudden, severe symptom that feels out of the ordinary
