High blood pressure (hypertension) is a common condition in which the long-term force of the blood against your artery walls is high enough that it may eventually cause health problems, such as heart disease.

Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease. With high cholesterol, you can develop fatty deposits in your blood vessels.

Dyslipidaemia is a preferable term to hyperlipidaemia because it includes risk factors such as a decreased concentration of high density lipoprotein (HDL) cholesterol as well as qualitative changes in low density lipoprotein (LDL), notably the presence of small, dense LDL particles.

The usual cause is the build-up of plaque. This causes coronary arteries to narrow, limiting blood flow to the heart. Coronary artery disease can range from no symptoms, to chest pain, to a heart attack. Treatments include lifestyle changes, medication, angioplasty and surgery.

Cardiomyopathy (kahr-dee-o-my-OP-uh-thee) is a disease of the heart muscle that makes it harder for your heart to pump blood to the rest of your body. Cardiomyopathy can lead to heart failure. The main types of cardiomyopathy include dilated, hypertrophic and restrictive cardiomyopathy.

Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot forms in a deep vein. These clots usually develop in the lower leg, thigh, or pelvis, but they can also occur in the arm.

Varicose veins are twisted, enlarged veins. Any superficial vein may become varicosed, but the veins most commonly affected are those in your legs. That's because standing and walking upright increases the pressure in the veins of your lower body.
