Acute coronary syndrome occurs when there isn't enough blood flowing through your heart. It can be felt as chest pain (angina) or a heart attack.
Daily fevers, achy joints and an intermittent, salmon-pink rash may be an indication that you have a rare inflammatory disorder called adult Still's disease.
Angina is a common type of chest pain caused by coronary artery disease. Unstable angina can be a warning sign of a heart attack.
Acute respiratory distress syndrome (ARDS) is a sudden and serious lung failure that develops in people who are critically ill or have major injuries.
Atrial septal defect (ASD) is an abnormal opening between the heart's upper pumping chambers. It's common and readily treated.
Atrioventricular canal defect is a congenital heart defect involving a hole in the center of the heart and abnormal valves between the heart's chambers.
Broken heart syndrome, also called stress cardiomyopathy, mimics a heart attack. Discover how stress could trigger this puzzling condition.
Brucellosis is an infectious disease that spreads from animals to people, mainly via unpasteurized dairy products. Travelers should take special care to avoid infection.
Bundle branch block is a disorder that affects the electrical impulses traveling to your heart. It may be a sign of underlying heart disease.
Cardiomyopathy is a heart muscle disease. Treatment options depend on what type of cardiomyopathy you have.
Coarctation of the aorta is a cardiovascular defect resulting in a narrowing of the aorta, the blood vessel that delivers oxygen-rich blood to your body.
Conjoined twins are identical twins most often joined at the chest, head or pelvis. In some cases, conjoined twins can be surgically separated.
Dressler's syndrome is a complication of a heart attack, heart surgery or other traumatic injury to the heart.
Ebstein's anomaly is a rare heart defect. Some people may not have any symptoms, but others may need treatment, including surgery.
Ehlers-Danlos syndrome (EDS) includes a group of uncommon genetic disorders that mainly affect the joints, skin and walls of blood vessels.
Eisenmenger syndrome, a complication of congenital heart defects, can be life-threatening if not properly treated. Find out more.
Enlarged heart is often a sign of a serious heart condition. Find out causes and treatments for enlarged heart.
Heart disease, usually thought of as blockages in the arteries that can cause a heart attack, can describe any medical condition affecting your heart.
Heart failure means your heart can't efficiently pump blood throughout your body. Medications, and sometimes devices or surgery, can help you manage this condition.
Heart palpitations are skipped, fluttering or racing heartbeats that aren't usually a symptom of a serious heart problem. Discover the causes and symptoms of this condition.
High blood pressure in children and adolescents is often caused by another health condition, but is usually treatable with diet and exercise.
Hypertrophic cardiomyopathy is a genetic disorder in which heart muscle becomes abnormally thick. It's the most common cause of sudden cardiac death in young people.
Hypoplastic left heart syndrome is a rare and complex congenital heart condition in which the left side of the heart is underdeveloped.
Kawasaki disease — the leading cause of acquired coronary disease in children — causes artery wall inflammation throughout the body. It affects children younger than age 5.
Left ventricular hypertrophy, thickening of the wall of your heart's main pumping chamber, increases your risk of cardiovascular diseases.
Low blood pressure (hypotension) can be a sign of good health or of a life-threatening condition. Find out more about hypotension's causes and treatment options.
Mitral valve prolapse occurs when the valve separating two of your heart's chambers malfunctions. The disorder usually isn't serious and often doesn't require surgical treatment.
Myocardial ischemia is a heart problem that occurs when blood flow to your heart muscle is decreased, reducing the heart's oxygen supply.
Myocarditis is a disease in which the heart muscle becomes inflamed and swollen, often as the result of an infection.
Noonan syndrome is caused by a mutation in one of the genes responsible for normal development in many parts of the body, including the heart.
Orthostatic hypotension (postural hypotension) is a form of low blood pressure that occurs when you stand up.
Patent ductus arteriosus (PDA) is a persistent, abnormal opening between the aorta and pulmonary artery. If it doesn't resolve on its own, it's readily treated.
Patent foramen ovale, an opening between the heart's upper chambers, usually doesn't require treatment.
Pericardial effusion, the accumulation of excess fluid in the sac-like structure around the heart, can decrease heart function and can be life-threatening.
Having a preemie can be overwhelming. Here's what you need to know about your baby's care and the possible complications of a premature birth.
Pulmonary atresia is a heart defect that you're born with. Fortunately, treatment soon after birth and ongoing throughout childhood and adulthood greatly improve your prognosis.
Pulmonary fibrosis results from scar tissue that forms in your lungs. This affects your ability to breathe and obtain enough oxygen.
High blood pressure affecting only the arteries in your lungs is known as pulmonary hypertension. Discover the symptoms, risk factors and treatment for this condition.
Pulmonary valve stenosis is a narrowing of the valve that controls blood flow from your heart to your lungs. It's usually present at birth.
Rheumatic fever, an inflammatory disease triggered by untreated or poorly treated strep throat, can cause permanent heart damage.
Stroke occurs when the blood supply to part of your brain is interrupted, depriving brain tissue of oxygen and nutrients. Stroke is a medical emergency.
Sudden cardiac arrest is a medical emergency. Rapid treatment improves your chances of survival.
Tetralogy of Fallot, a cause of "blue baby" syndrome, is a congenital heart condition resulting in oxygen-poor blood leaving the heart and entering the body.
Transposition of the great arteries is a congenital heart defect in which the placement of the aorta and the pulmonary artery is switched.
A heart with tricuspid atresia doesn't have a tricuspid valve. This heart defect prevents blood flow from the right atrium to the right ventricle.
Vasovagal syncope (fainting) is a sudden and brief loss of consciousness that occurs when the blood flow to your brain is markedly reduced.
