Introduction
Oral contraceptives are widely used, with millions of women relying on them to regulate their menstrual cycles, prevent pregnancy, and relieve symptoms associated with premenstrual syndrome. However, research has shown that oral contraceptives may increase the risk of cardiovascular disease, which is the leading cause of death worldwide.
This article will look at the cardiovascular risk factors associated with using oral contraceptives, as well as the management of cardiovascular risk in women who use oral contraceptives.
What Are the Common Cardiovascular Diseases Seen in Women on Oral Contraceptives?
Women who use oral contraception are at a higher risk of developing several cardiovascular diseases, including:
1. Deep Vein Thrombosis (DVT): DVT is a condition in which blood clots form in the deep veins of the arms or legs. The risk of developing DVT is higher in women who take oral contraceptives due to the increased levels of estrogen in their bodies.
2. Pulmonary Embolism (PE): PE is a critical medical condition that happens when a blood clot dislodges from its site of origin and travels to the lungs, where it blocks a blood vessel, leading to reduced blood flow to the affected area of the lung.
3. Stroke: Because of the increased risk of blood clots and hypertension, women on oral contraceptives are at an increased risk of stroke.
4. Heart Attack: Oral contraceptives have been linked to an increased risk of heart attack, particularly in women who smoke or have other cardiovascular risk factors.
5. Hypertension: Oral contraceptives can raise blood pressure in some women, resulting in hypertension.
What Are the Cardiovascular Risk Factors?
Cardiovascular disorders(CVD) are governed by a number of risk factors, including.
-
Age: As age increases, the risk of developing CVD increases. This is because the blood vessels become less flexible and more prone to damage over time, which can lead to conditions like atherosclerosis.
-
Gender: Men are generally more likely than pre-menopausal women to develop CVD. However, after menopause, women's CVD risk rises to match that of men.
-
Family History: A family history of CVD, especially involving a first-degree relative (parent or sibling), raises the risk of developing CVD. This suggests that the disease may have a genetic component.
-
Smoking: Cigarette smoking is a significant contributor to the development of cardiovascular disease (CVD). It damages the blood vessel lining, raises blood pressure and heart rate, and promotes the formation of fatty deposits in the arteries.
-
Diabetes: Diabetes patients are at a higher risk of developing CVD. This is due to the fact that high blood sugar levels can cause blood vessel damage and increase the risk of atherosclerosis.
-
Hypertension: Elevated blood pressure is a significant risk factor for CVD as it causes the heart and blood vessels to work harder, which can result in harm and a greater possibility of heart attack and stroke.
-
Dyslipidemia: Dyslipidemia refers to abnormal levels of cholesterol and other fats in the blood. Elevated levels of LDL cholesterol, commonly referred to as bad cholesterol, can contribute to the development of atherosclerosis and increase the risk of CVD.
What Is Oral Contraceptive and How Does It Cause Cardiovascular Diseases?
Oral Contraceptives (OCs) are hormonal medications that contain synthetic estrogen and progestin. They are widely used for birth control and other indications, such as menstrual irregularities, acne, and polycystic ovary syndrome. The hormonal components of OCs can affect various physiological processes, including coagulation, lipid metabolism, and endothelial function, which can impact cardiovascular risk.
The cardiovascular risks associated with OC use are largely dependent on the dose and type of hormones used in the medication, as well as the individual's underlying cardiovascular risk factors.
According to some studies, using OCs may increase the risk of arterial thrombosis, which can lead to Myocardial infarction, stroke, and other cardiovascular events. This risk is thought to be higher in women who smoke, have a history of thrombosis, or have other cardiovascular risk factors.
Role Of Smoking In Women On Oral Contraceptives:
-
Oral contraceptive use has been linked to an increased risk of blood clots, stroke, and heart attacks in women, making it a risk factor for cardiovascular disease when combined with smoking.
-
When compared to non-smokers who use oral contraceptives, women who smoke and use oral contraceptives have a higher risk of blood clots, stroke, and heart attacks.
-
Several studies have found that smoking and oral contraceptive use increase the risk of Venous thromboembolism significantly more than non-smoking oral contraceptive users.
Studies have shown that third-generation OCs may increase the risk of Venous Thromboembolism (VTE) compared to second-generation OCs. This increased risk is thought to be due to the higher estrogen dose and the use of newer types of progestin, which have been shown to have a greater impact on coagulation and fibrinolysis than the older progestin used in second-generation OCs.
By altering some of these risk factors, oral contraceptives raise the risk of CVD by:
-
Estrogen in oral contraceptives raises the risk of thrombosis by increasing coagulation factor production while decreasing fibrinolysis.
-
Estrogen also reduces the clearance of low-density lipoprotein cholesterol (LDL), resulting in dyslipidemia.
-
Progestins in oral contraceptives may also contribute to dyslipidemia by raising triglyceride levels and lowering HDL cholesterol.
Women using oral contraception should be aware of these potential cardiovascular risks and discuss any concerns with their healthcare provider. Women taking oral contraceptives may require regular monitoring and management of cardiovascular risk factors such as blood pressure and cholesterol levels.
How to Prevent and Manage Cardiovascular Diseases in Women Using Oral Contraceptives?
The management of cardiovascular risk in women who use oral contraceptives (OCs) involves a multidisciplinary approach that includes regular cardiovascular assessments, individualized counseling, and medication management.
1. Cardiovascular Assessment
-
Women who use OCs should undergo regular cardiovascular risk assessments, including blood pressure checks and lipid profiles.
-
Women with underlying cardiovascular risk factors, such as hypertension, diabetes, or a family history of cardiovascular disease, may need more frequent monitoring.
-
Women who smoke or have a history of thrombosis should be routinely watched for cardiovascular problems.
2. Individual Counselling
-
Women who use OCs should receive individualized counseling to discuss their specific cardiovascular risks and benefits.
-
Women with significant underlying cardiovascular risk factors should be informed about the potential cardiovascular risks associated with OC use and advised to consider alternative methods of contraception.
3. Medication Management
-
The type and dose of hormones used in OCs can have different effects on cardiovascular risk. Some hormonal contraceptives may raise the risk of blood clots and cardiovascular events, whereas others may be neutral or protective.
-
For example:
-
Research has indicated that some women, especially those with a history of cardiovascular disease, high blood pressure or who smoke, may experience an increased risk of blood clots and stroke when using estrogen-containing oral contraceptives.
-
Contraceptives that only contain progestin are generally considered safe for women with cardiovascular risk factors, though they may have a slightly higher risk of blood clots than combined hormonal contraceptives.
-
As a result, if a woman has a history of cardiovascular disease or risk factors for heart disease, the healthcare provider may advise the patient to use a progestin-only method of contraception or a non-hormonal method, such as a copper intrauterine device (IUD).
-
For women who have significant cardiovascular risk factors, other medications may be recommended to manage their risk. For example, statins may be prescribed to manage dyslipidemia, and antihypertensive medications may be prescribed to manage hypertension.
Conclusion
Oral contraceptives (OCs) have both positive and negative effects on cardiovascular health. The risk of cardiovascular disease (CVD) depends on the type and dose of hormones used in the medication and individual cardiovascular risk factors. Second-generation OCs are less likely to cause CVD than first-generation OCs, while third-generation OCs may increase the risk of venous thromboembolism compared to second-generation OCs.
Regular cardiovascular risk assessments and considering other cardiovascular risk factors are critical for women who use oral contraceptives (OCs). Women who are at higher risk of cardiovascular disease should consider alternative contraception methods. The type and dose of OC should be tailored to the individual to reduce the risk of CVD while maintaining the benefits of contraception.
