THIS IS A GUESS!!! silent killer means that you might die instantly. If you have a high blood pressure, you might die.
Silent killer means that there are not any overt symptoms when your blood pressure is high.

Example, generally, you can't feel that your blood pressure is high (like pain) and therefore, you won't know to see a doctor for treatment.

Generally, untreated HBP damages blood vessels and causes the heart to enlarge.
HBP can also cause strokes in the brain.
