Systolic blood pressure of a patient was 140 mm Hg while his diastolic blood pressure is 90 mm Hg . If this is not controlled , it can lead to
(a) Heart disease
(b) Brain hemorrhage
(c) Damage of the blood vessels of kidney
(d) Failure in conducting system

Options

A. a,b,c and d
B. a, b and c
C. Only a and b
D. b and c only

Answer

To solve the question regarding the implications of a systolic blood pressure of 140 mm Hg and a diastolic blood pressure of 90 mm Hg, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Blood Pressure Readings**:
- Blood pressure is measured in millimeters of mercury (mm Hg) and consists of two numbers: systolic (the pressure when the heart beats) and diastolic (the pressure when the heart is at rest).
- Normal blood pressure is typically around 120/80 mm Hg.

2. **Identifying Hypertension**:
- A reading of 140/90 mm Hg indicates hypertension, which is a condition where the blood pressure is consistently too high.
- Hypertension can lead to various health complications if not managed.

3. **Potential Complications of Hypertension**:
- **Heart Disease**: High blood pressure can lead to the thickening of the heart muscle and increase the risk of heart attacks.
- **Brain Hemorrhage**: Hypertension can cause blood vessels in the brain to rupture, leading to strokes or brain hemorrhages.
- **Kidney Damage**: The kidneys filter blood and can be damaged by the high pressure, leading to kidney disease or failure.

4. **Evaluating the Options**:
- (a) Heart disease: Possible due to long-term hypertension.
- (b) Brain hemorrhage: Possible due to high blood pressure affecting cerebral blood vessels.
- (c) Damage of the blood vessels of the kidney: Possible due to hypertension affecting renal blood flow.
- (d) Failure in conducting system: This is less relevant as hypertension primarily affects organs rather than the conducting system of the heart.

5. **Conclusion**:
- Since options (a), (b), and (c) are all potential complications of uncontrolled hypertension, the most direct answer to the question is **(b) Brain hemorrhage**, as it is a severe and acute consequence of high blood pressure.

### Final Answer:
(b) Brain hemorrhage
