Calcium channel blockers and CHD

High blood pressure is a risk factor for patients with CHD. Calcium channel blockers are able to lower high blood pressure by relaxing muscles fibres found in the walls of blood vessels. This relaxing effect of the blood vessel muscles results in the arteries becoming wider. The widening in turn leads to a reduction of high blood pressure.

There are a number of calcium channel blocker medicines. Three examples are:

  1. Amlodipine
  2. Verapamil
  3. Diltiazem

As with nearly all medicines there are side effects that may occur. Some of the common side effects that may occur in some patients include headache and facial flushing, but theses side effects are usually mild and tend to resolve over time.

Diuretics and CHD

Having too much water in the blood can contribute to a raised blood pressure. Medicines called diuretics allow the body to remove excess water and salt via the kidneys in the form of urine.
