C. If the blood pressure is 220/120 mm Hg it can lead to cerebrovascular accident
D. Hypertension can lead to 'angina pectoris'.

Answer

To determine which statement is not true about blood pressure, we will analyze each statement provided:

1. **High blood pressure leads to heart diseases and also affects vital organs like the brain and kidneys.**
- This statement is true. High blood pressure (hypertension) can cause damage to the heart and other vital organs over time.

2. **If the blood pressure of an individual is 140 by 90 mm Hg or higher, it is called hypertension.**
- This statement is also true. A blood pressure reading of 140/90 mm Hg or higher is classified as hypertension.

3. **If the blood pressure is 220 by 120 mm Hg, it can lead to cardiovascular accidents.**
- This statement is true as well. A reading of 220/120 mm Hg is considered severely high and can increase the risk of cardiovascular events such as strokes.

4. **Hypertension can lead to angina pectoris.**
- This statement is not true. Angina pectoris is characterized by chest pain due to inadequate blood supply to the heart muscle, but it is not directly caused by hypertension. Instead, it is often related to coronary artery disease.

Based on the analysis, the statement that is not true about blood pressure is: **"Hypertension can lead to angina pectoris."**
