While reducing the risk factors and lowering the risk of developing cardiovascular disease (CVD) is the best option, CVD is still very common and treatment options are needed
There are a number of different?treatment options?for cardiovascular disease, many of which?involve taking?medication
Types of medication for the treatment of CVD include
Antihypertensives
Statins
Anticoagulants
Platelet inhibitors
Antihypertensives
These drugs work by?lowering blood pressure
High blood pressure is also known as?hypertension
Lowering blood pressure?reduces the risk of arterial endothelial damage?and therefore reduces the risk of atheromas and thrombosis
Beta blockers,?vasodilators?and?diuretics?act as antihypertensives
Beta blockers prevent increases in heart rate
Vasodilators increase the diameter of the blood vessels
Diuretics reduce blood volume by decreasing the amount of sodium reabsorbed into the blood by the kidneys, therefore decreasing the volume of water reabsorbed into the blood
Statins
These drugs work by?lowering blood cholesterol
They block an enzyme in the liver which is needed to make cholesterol
This?lowers the LDL concentration?in the blood therefore reducing the risk of atheroma formation
LDLs are sometimes known as 'bad' cholesterol; at high levels they increase the risk of atheromas forming
Anticoagulants
These drugs?reduce blood clotting
Blood clotting can be referred to as blood coagulation
Reduced formation of blood clots?decreases the likelihood of thrombosis?and therefore reduces the risk of blood vessels being blocked by blood clots
Platelet inhibitors
These are also substances which?reduce blood clotting
Platelet inhibitors are a type of anticoagulant
They prevent the clumping together of?platelets,?so preventing the formation of blood clots
Aspirin?is an example?of a platelet inhibitor
Benefits and Risks of Cardiovascular Disease Drugs Table
Exam Tip
You need to know these four examples and their associated benefits and risks.? Be sure to be specific on how each medication type prevents CVD.
