What are the hypertensive disorders in pregnancy?
The 4 categories of hypertensive disorders of pregnancy are chronic hypertension, gestational hypertension, preeclampsia-eclampsia, and chronic hypertension with superimposed preeclampsia. These disorders are among the leading causes of maternal and fetal morbidity and mortality.
What is the difference between gestational hypertension and chronic hypertension?
Gestational hypertension is high blood pressure in pregnancy. It occurs in about 3 in 50 pregnancies. This condition is different from chronic hypertension. Chronic hypertension happens when a woman has high blood pressure before she gets pregnant.
What causes hypertension in pregnancy?
The cause of gestational hypertension is unknown. Some conditions may increase the risk of developing the condition, including the following: Pre-existing hypertension (high blood pressure) Kidney disease.
Which classification of hypertension in pregnancy is no longer recommended?
The use of automated BP measuring devices is not recommended because they tend to under-record BP and they are unreliable in pre-eclampsia . Hypertension disorders in pregnancy (HDP) are classified into mild HTN (systolic BP 140-159 mmHg and/or diastolic BP 90-109 mmHg) or severe HTN (BP ≥160/110 mmHg) .
WHO classification pregnancy-induced hypertension?
Pregnancy-induced hypertension (PIH) complicates 6-10% of pregnancies. It is defined as systolic blood pressure (SBP) >140 mmHg and diastolic blood pressure (DBP) >90 mmHg. It is classified as mild (SBP 140-149 and DBP 90-99 mmHg), moderate (SBP 150-159 and DBP 100-109 mmHg) and severe (SBP ≥ 160 and DBP ≥ 110 mmHg).
What blood pressure is considered gestational hypertension?
After 20 weeks of pregnancy, blood pressure that exceeds 140/90 mm Hg — documented on two or more occasions, at least four hours apart, without any other organ damage — is considered to be gestational hypertension.
What is the difference between preeclampsia and pregnancy induced hypertension?
Pregnancy-induced hypertension is a rise in blood pressure, without proteinuria, during the second half of pregnancy. Pre-eclampsia is a multisystem disorder, unique to pregnancy, that is usually associated with raised blood pressure and proteinuria. It rarely presents before 20 weeks’ gestation.
What is the normal blood pressure during pregnancy?
– mild hypertension is when your top figure is between 140 and 149 and your bottom figure is between 90 and 99 – moderate hypertension is when your top figure is between 150 and 159 and your bottom figure is between 100 and 109 – severe hypertension is when your top figure is 160 or greater and your bottom figure is 110 or greater
What are the diagnostic criteria for gestational hypertension?
– Chronic/pre-existing hypertension. Hypertension discovered preconception or prior to 20 weeks’ gestation. – Gestational hypertension. Hypertension that appears de novo after 20 weeks’ gestation and normalizes after pregnancy. – Preeclampsia-eclampsia.
