HypertensionHypertension
• Hypertension means “high pressure”Hypertension means “high pressure”
• Blood pressure is the force that the blood exerts, drivenBlood pressure is the force that the blood exerts, driven
by the heart. This pressure has two values:by the heart. This pressure has two values: systolicsystolic
pressurepressure (when the ventricles contract) and(when the ventricles contract) and diastolicdiastolic
pressurepressure (when the heart is relaxed)(when the heart is relaxed)
• Normal pressure is around 120 mm Hg (systolic) and 70-80Normal pressure is around 120 mm Hg (systolic) and 70-80
mm Hg (diastolic)mm Hg (diastolic)
• Hypertension occurs if the systolic pressure is over 140 mm HgHypertension occurs if the systolic pressure is over 140 mm Hg
or the diastolic pressure is over 100 mm Hgor the diastolic pressure is over 100 mm Hg
• Causes of high blood pressure include:Causes of high blood pressure include:
• Stress, consumption of stimulants (tobacco, caffeine, etc),Stress, consumption of stimulants (tobacco, caffeine, etc),
excess weight, excess salt in the dietexcess weight, excess salt in the diet
HypotensionHypotension
• Opposite of hypertension, when the blood pressure is veryOpposite of hypertension, when the blood pressure is very

flowing back through the veinsflowing back through the veins
• Blood accumulates inside the veinsBlood accumulates inside the veins
AneurysmAneurysm

Blood Vessel ObstructionBlood Vessel Obstruction
• StrokeStroke – produced when the interruption of blood supply– produced when the interruption of blood supply
affects a region of the brain, either due to a blood vesselaffects a region of the brain, either due to a blood vessel
breaking or becoming obstructedbreaking or becoming obstructed
• Embolism –Embolism – caused by blood clots, which dislodge andcaused by blood clots, which dislodge and
