CHARACTERISTICS OF THE FIRST ORGANS DAMAGED IN HYPERTENSION THE BRAIN, HEART AND KIDNEYS

Systemic arterial hypertension is characterized by persistently high blood pressure (BP) in the systemic arteries. BP is commonly expressed as the ratio of the systolic BP (that is, the pressure that the blood exerts on the hypertension depend on the measurement method. Several aetiologies can underlie arterial walls when the heart contracts) and the diastolic BP.The BP thresholds that define hypertension. The majority (90 90–95%) of patients have a highly heterogeneous essential or primary hypertension with a multifactorial gene gene-environment aetiology.
