Definition and Classification

Hypertensive disorders of pregnancy (HDP) are a group of conditions characterized by high blood pressure during pregnancy, which can lead to significant maternal and fetal morbidity and mortality. The American College of Obstetricians and Gynecologists (ACOG) classifies HDP into four categories:

1. *Gestational Hypertension*: New-onset hypertension after 20 weeks of gestation without proteinuria or other signs of organ damage.

2. *Preeclampsia*: New-onset hypertension after 20 weeks of gestation with proteinuria (excess protein in the urine) or other signs of organ damage.

3. *Chronic Hypertension*: Pre-existing hypertension before pregnancy or diagnosed before 20 weeks of gestation.

4. *Chronic Hypertension with Superimposed Preeclampsia*: Pre-existing hypertension with new-onset proteinuria or other signs of organ damage after 20 weeks of gestation.

Risk Factors

Several risk factors increase the likelihood of developing HDP:

1. *Previous history of HDP*

2. *Chronic medical conditions* (e.g., hypertension, diabetes, kidney disease)

3. *Multiple gestations* (e.g., twins, triplets)

4. *Family history of HDP*

5. *Age > 35 years*

6. *Obesity*

7. *Socioeconomic factors* (e.g., low income, limited access to healthcare)

Clinical Presentation

HDP can present with a range of symptoms, including:

1. *Hypertension*: Blood pressure ≥140/90 mmHg

2. *Proteinuria*: Excess protein in the urine

3. *Severe headache*

4. *Visual disturbances* (e.g., blurred vision, double vision)

5. *Abdominal pain*

6. *Nausea and vomiting*

7. *Edema* (swelling of hands, feet, and face)

Diagnosis

Diagnosis of HDP is based on:

1. *Blood pressure measurement*: ≥140/90 mmHg

2. *Urine protein-to-creatinine ratio*: ≥0.3 mg/mg

3. *Laboratory tests*: Complete blood count, liver function tests, and renal function tests

4. *Imaging studies*: Ultrasound to assess fetal growth and well-being

Management

Management of HDP depends on the severity of the condition and the gestational age:

1. *Mild HDP*: Close monitoring of blood pressure and fetal well-being, with possible outpatient management.

2. *Severe HDP*: Hospitalization for close monitoring and possible delivery, regardless of gestational age.

3. *Preeclampsia with severe features*: Immediate delivery, regardless of gestational age.

4. *Chronic hypertension*: Continued management of hypertension, with possible adjustment of medications.

Complications

HDP can lead to significant maternal and fetal complications, including:

1. *Maternal complications*:

    - Stroke

    - Seizures

    - Liver failure

    - Kidney failure

    - Placental abruption

2. *Fetal complications*:

    - Growth restriction

    - Premature birth

    - Low birth weight

    - Stillbirth

Prevention

While there is no surefire way to prevent HDP, several strategies can reduce the risk:

1. *Preconception counseling*: Identifying and managing underlying medical conditions before pregnancy.

2. *Early prenatal care*: Regular monitoring of blood pressure and fetal well-being.

3. *Lifestyle modifications*: Maintaining a healthy weight, following a balanced diet, and engaging in regular physical activity.

4. *Aspirin prophylaxis*: Low-dose aspirin therapy for high-risk women.
