Contraception Recommendations for Women with Multiple Cardiovascular Risk Factors

Introduction to Contraceptive Options

The American College of Cardiology recommends that women with poorly controlled hypertension, smoking history, obesity, and age over 35 use progestin-only contraceptives or non-hormonal methods, as combined hormonal contraceptives are absolutely contraindicated due to the increased risk of cardiovascular events 1, 2, 3

Women with systolic blood pressure ≥160 or diastolic ≥100 mmHg have a Category 4 contraindication to combined hormonal methods, according to the MMWR Recommendations and Reports 2, 4
The combination of poorly controlled hypertension, age >35 years, smoking history, and obesity creates a 6.1-68.1 times higher risk of myocardial infarction compared to women without these risk factors, as stated by the Praxis Medical Insights 3
The risk of ischemic stroke increases 8-15 fold in hypertensive women using combined oral contraceptives versus women without either risk factor, according to the Praxis Medical Insights 3

Progestin-only pills are Category 2 for women with poorly controlled hypertension, with no significant association with elevated blood pressure in studies, as reported by the MMWR Recommendations and Reports 2, 4
The etonogestrel implant is Category 2 for women with poorly controlled hypertension and is highly effective with no daily adherence requirements, according to the MMWR Recommendations and Reports and Praxis Medical Insights 2, 4, 5
The levonorgestrel IUD is Category 2 for women with poorly controlled hypertension, with minimal systemic hormone absorption, as stated by the MMWR Recommendations and Reports 2, 4
The copper IUD is Category 1 for all conditions, including poorly controlled hypertension, obesity, smoking, depression, and headaches, with no hormonal effects on blood pressure or cardiovascular risk, according to the MMWR Recommendations and Reports 2, 4

Blood pressure must be properly measured and documented on at least two separate occasions to confirm severity, with differences >20 mmHg systolic or >10 mmHg diastolic requiring vascular evaluation, as recommended by the European Heart Journal 6
The patient's poorly controlled hypertension must be addressed urgently before or concurrent with contraceptive initiation, with a goal blood pressure <130/80 mmHg, according to the Journal of the American College of Cardiology 1

Blood pressure must be checked at least every 6 months for any woman using hormonal contraceptives, and more frequently until hypertension is controlled, as stated by the Praxis Medical Insights 3, 5

Current smokers using combined hormonal contraceptives have a 10-fold increased risk of myocardial infarction, but progestin-only methods remain safer options, according to the MMWR Recommendations and Reports 2
Obesity alone is Category 2 for combined methods, but combined with other risk factors makes them Category 4, while progestin-only pills, implants, and both IUDs are Category 1 for obesity, as reported by the MMWR Recommendations and Reports 2, 4
All contraceptive methods are Category 1 for depressive disorders, according to the MMWR Recommendations and Reports 2, 4
Non-migrainous headaches are Category 1-2 for progestin-only methods, with monitoring required for any change in headache pattern, as stated by the MMWR Recommendations and Reports and Stroke 2, 4, 7

The American Heart Association recommends that combined hormonal contraceptives containing ≥20 mcg ethinyl estradiol are associated with measurable blood pressure elevations, with systolic BP increases of 0.7-5.8 mmHg and diastolic BP increases of 0.4-3.6 mmHg 8
Women with uncontrolled hypertension face a higher risk and have an absolute Category 4 contraindication for combined hormonal contraceptives, according to the American College of Cardiology 9
The hypertensive effect of combined hormonal contraceptives is related to the progestogenic potency of the preparation, not the estrogenic component, as stated by the European Society of Cardiology 10
Progestin-only pills, such as norethindrone or drospirenone, have a failure rate of 6-12% with typical use and are associated with irregular bleeding patterns, according to the World Health Organization 8, 9

The Copper Intrauterine Device (IUD) has a failure rate of <1% with typical use and is considered a Category 1 option for all women with hypertension, regardless of severity or control status, by the American College of Obstetricians and Gynecologists 9
The Levonorgestrel Intrauterine Device has a failure rate of <1% with typical use and is considered a Category 2 option for women with poorly controlled hypertension, as recommended by the National Institute for Health and Care Excellence 9
The Etonogestrel Subdermal Implant has a failure rate of <1% with typical use and is considered a Category 2 option for women with poorly controlled hypertension, according to the Faculty of Sexual and Reproductive Healthcare 9

The American Heart Association recommends checking blood pressure at least every 6 months for any woman using hormonal contraceptives, including progestin-only methods, with more frequent monitoring required until hypertension is controlled 10
If hypertension develops or worsens on combined hormonal contraceptives, discontinuation is recommended, as blood pressure typically returns to baseline within 2-6 months, according to the European Society of Cardiology 8, 10
