Heart, blood vessel, cholesterol, clotting, and stroke-related guides.
Aortic aneurysm (abdominal)
An abdominal aortic aneurysm (AAA) is a bulge in the lower part of the aorta, the body's largest artery, as it passes through the abdomen. The weakened.
Heart & CirculationBlood clots
Blood clots (thrombosis) form when blood thickens and clumps together inside blood vessels. A clot in a deep vein (deep vein thrombosis, DVT) most commonly.
Heart & CirculationCoronary artery disease
Coronary artery disease (CAD) is the narrowing or blockage of the arteries that supply blood and oxygen to the heart muscle, caused by a build-up of fatty.
Heart & CirculationHeart arrhythmias
Heart arrhythmias are abnormal heart rhythms where the heart beats too fast (tachycardia), too slow (bradycardia), or in an irregular pattern. Atrial.
Heart & CirculationHeart attack
A heart attack (myocardial infarction) occurs when the blood supply to part of the heart muscle is suddenly blocked, usually by a blood clot forming on top.
Heart & CirculationHeart failure
Heart failure is a condition where the heart cannot pump blood efficiently enough to meet the body's needs. Despite the name, the heart does not stop.
Heart & CirculationHeart valve disease
Heart valve disease occurs when one or more of the four heart valves do not work properly. A valve may be too narrow (stenosis, limiting blood flow) or may.
Heart & CirculationHigh blood pressure (hypertension)
Hypertension is persistently elevated blood pressure in the arteries. It is defined as readings consistently at or above 140/90 mmHg in clinic. Often.
Heart & CirculationHigh cholesterol
High cholesterol (hypercholesterolaemia) means there is too much cholesterol in the blood, particularly low-density lipoprotein (LDL) cholesterol. Excess.
Heart & CirculationPeripheral artery disease
Peripheral artery disease (PAD) is narrowing of the arteries supplying blood to the legs (and sometimes arms), caused by atherosclerosis. It reduces blood.
Heart & CirculationStroke
A stroke happens when blood flow to part of the brain stops. Learn the FAST warning signs, why every minute matters, and how treatment and recovery begin in hospital.
Heart & CirculationVaricose veins
Varicose veins are enlarged, twisted veins that most commonly appear in the legs. They develop when the one-way valves inside veins fail, allowing blood to.
