Study Population

Participants will be selected from hospital/policlinic database by random telephone dialing to every third patient who are diagnosed with arterial hypertension (SBP/DBP\>140/90 Hg or taking antihypertensive drugs)

You may qualify if:

  • Cases: every third patient from hospital/policlinic database who are diagnosed with arterial hypertension (SBP/DBP\>140/90 Hg or taking anti hypertensive drugs) and with frequent (weekly or daily) hypertensive urgencies (SBP/DBP≥180/110 Hg) will be potentially eligible for the study.
  • Controls will be selected from the same population of participants by random telephone dialing to every third patient with arterial hypertension (SBP/DBP\>140/90 Hg or taking anti hypertensive drugs) and with seldom (monthly, several times in the year or never) hypertensive urgencies.

You may not qualify if:

  • Hypertensive emergency
