Treatments for CVD: Benefits & Risks
- 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
- ACE inhibitors are a type of drug that block the production of angiotensin, a hormone that causes constriction of the blood vessels
- This keeps the arteries dilated, which lowers the blood pressure
- 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
- Statins also reduce inflammation in the arterial lining, which lowers the risk of atherosclerosis
Anticoagulants
- These drugs reduce blood clotting
- Blood clotting can be referred to as blood coagulation
- Warfarin is an anticoagulant that decreases the level of prothrombin in the bloodstream
- 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
- Aspirin and clopidogrel are the most commonly used examples of these drugs
- They prevent the clumping together of platelets, so preventing the formation of blood clots
