Management of Pregnant Patients with Multiple Comorbidities

Hypertension Management

The American College of Cardiology recommends initiating antihypertensive medication immediately in pregnant patients with blood pressure ≥140/90 mmHg, particularly those with a history of gestational hypertension and pre-eclampsia 1, 2
Target diastolic BP of 85 mmHg and systolic BP between 110-140 mmHg to ensure adequate uteroplacental perfusion 1, 2
First-line agents for hypertension management in pregnancy include oral methyldopa, labetalol, or nifedipine, as recommended by the European Society of Cardiology 3, 1, 2
The American Heart Association recommends discontinuing propranolol due to its association with fetal growth retardation when used long-term during pregnancy 3
Labetalol is the preferred beta-blocker for anxiety/hypertension in pregnancy, as recommended by the European Society of Cardiology 3, 1

The European Society of Cardiology recommends obtaining urine culture immediately and initiating empiric antibiotic therapy in pregnant patients with suspected UTI 3
Safe antibiotics in pregnancy include nitrofurantoin, amoxicillin-clavulanate, or cephalexin, as recommended by the European Society of Cardiology 3

The American Academy of Family Physicians recommends increasing folic acid supplementation to 4 mg daily in pregnant patients taking antiepileptic drugs, such as levetiracetam, to reduce neural tube defect risk 4

The American Society of Hematology recommends obtaining baseline platelet count immediately and monitoring platelet counts monthly in the first and second trimesters, and every 2 weeks in the third trimester 5, 6
No treatment is needed if platelet count remains ≥20-30 × 10⁹/L and patient is asymptomatic throughout the first two trimesters, as recommended by the American Society of Hematology 5, 6, 7
Treatment is indicated if patient becomes symptomatic with bleeding, platelet count falls below 20-30 × 10⁹/L, or procedures are planned, as recommended by the American Society of Hematology 5, 6
Target platelet count ≥50 × 10⁹/L for vaginal delivery or cesarean section, and ≥75 × 10⁹/L if epidural/spinal anesthesia is desired, as recommended by the American Society of Hematology 5, 6, 7

The American College of Cardiology recommends considering low-dose aspirin prophylaxis in pregnant patients with a history of early-onset pre-eclampsia, although evidence is mixed 3
Monitor for proteinuria at every visit, and obtain 24-hour urine collection or protein/creatinine ratio if dipstick shows ≥1+ protein, as recommended by the American College of Cardiology 3, 1, 2
BP ≥170/110 mmHg is a hypertensive emergency requiring hospitalization, as recommended by the American College of Cardiology 3, 1

Establish a care team including an obstetrician experienced in high-risk pregnancy, hematologist, neurologist, and obstetric anesthetist, as recommended by the American Society of Hematology 5, 6, 7

Most antihypertensives are compatible with breastfeeding, though specific agent selection should consider this, as recommended by the American College of Cardiology 1
Sertraline has relatively low breast milk transfer and is generally considered compatible with breastfeeding, as recommended by the European Society of Cardiology 3

Do not use atenolol or propranolol long-term due to their association with fetal growth restriction, as recommended by the European Society of Cardiology 3
Do not withhold antihypertensive treatment, as untreated hypertension ≥140/90 mmHg increases maternal and fetal morbidity, as recommended by the American College of Cardiology 1, 2
Do not delay ITP treatment if platelets fall or bleeding occurs, as maternal hemorrhage risk increases significantly, as recommended by the American Society of Hematology 5, 6
Do not discontinue levetiracetam without neurology consultation, as seizures during pregnancy pose greater risk than medication exposure, as recommended by the American Academy of Family Physicians 4
