Cardiovascular disease is caused by narrowed, blocked or stiffened blood vessels that make it so your heart, brain or other parts of your body don't receive enough blood. Cardiovascular disease symptoms can include:

* Chest pain (angina)
* Shortness of breath
* Pain, numbness, weakness or coldness in your legs or arms, if the blood vessels in those parts of your body are narrowed

You might not be diagnosed with cardiovascular disease until your condition worsens to the point that you have a heart attack, chest pain (angina), stroke, heart failure or sudden cardiac death. It's important to watch for cardiovascular symptoms and discuss any concerns with your doctor. Cardiovascular disease can sometimes be found early with regular visits to your doctor.

Heart disease symptoms caused by abnormal heartbeats (heart arrhythmias)
A heart arrhythmia is an abnormal heartbeat. Your heart may beat too quickly, too slowly, or irregularly if you have an arrhythmia. Heart arrhythmia symptoms can include:

* A fluttering in your chest
* A racing heartbeat (tachycardia)
* A slow heartbeat (bradycardia)
* Chest pain
* Shortness of breath
* Lightheadedness
* Dizziness
* Fainting (syncope) or near fainting

Heart disease symptoms caused by heart defects
Serious congenital heart defects — a defect you're born with — usually become evident during the first few hours, days, weeks and months of life. Heart defect symptoms could include:

* Pale gray or blue skin color (cyanosis)
* Swelling in the legs, abdomen or areas around the eyes
* Shortness of breath during feedings, leading to poor weight gain

Less-serious congenital heart defects are often not diagnosed until later in childhood, or even adulthood. Signs and symptoms of congenital heart defects that usually aren't immediately life-threatening include:

* Easily becoming short of breath during exercise or activity
* Easily tiring during exercise or activity
* Built-up fluid in the heart or lungs
* Swelling in the hands, ankles or feet
