Blood clotting is a natural process that occurs to prevent excessive bleeding. However, blood clots can also form on the inside of blood vessels.

Thrombosis is when a blood clot (thrombus) forms inside a blood vessel, potentially blocking the flow of blood through the circulatory system and causing serious health issues.

Heart and cardiovascular conditions can be life-changing. Understand the impact of these common conditions, and find out what you can do about them.

Heart failure is when the heart does not work as well as it should in pumping blood and oxygen around the body, causing extra fluid to build up in the body.

Cardiovascular disease (CVD) refers to all the diseases of the heart and circulation, including coronary heart disease, atrial fibrillation, heart attack, congenital heart disease and stroke.

Diabetes is a condition in which the body cannot maintain healthy blood glucose levels. People living with type 2 diabetes are over twice as likely to develop cardiovascular disease.

A stroke occurs when the brain does not get the blood supply that it needs.

Discover the key distinctions between cardiac arrest and heart attack. Learn about signs and symptoms, and how to react in each situation.

A heart attack occurs when the heart is deprived of oxygen due to a blockage in one of the coronary arteries that supplies blood to the heart.

A heart attack is a critical event. Know the symptoms and warning signs of heart attack in women so that you can seek emergency help immediately if you suspect a heart attack.

Coronary heart disease, also known as coronary artery disease, is a common condition where the major blood vessels to the heart become blocked and narrowed.

Acute coronary syndrome (ACS) is an umbrella term for situations where blood supply to the heart is blocked.

Peripheral artery disease (PAD) is a type of cardiovascular disease in which the narrowing of arteries results in reduced blood flow to a body part outside of the heart or brain.

Atherosclerotic plaque is composed of fat, cholesterol, calcium and inflammatory cells that build up on the inside of the body’s arteries.

Atherosclerosis is the main underlying cause of cardiovascular disease.

Congenital heart disease is a general term for problems with the heart’s structure that are present from birth. It is the most common type of birth defect.
