I'm a Heart Patient - Are Oral Contraceptive Pills Safe for Me?

I'm A Heart Patient - Are Oral Contraceptive Pills Safe For Me?

Introduction

Dialogues concerning sexuality, reproductive health, contraception, and sexually transmitted illnesses (STIs) are limited worldwide. One of the biggest reasons for these decreased dialogues is the fear of spreading indecency among the younger population. Unfortunately, the failure to discuss these topics has had a great impact on public health and led to an increase in the prevalence of abortions and STIs, such as HIV, in the country. The current abortion rate in Pakistan stands at 50 per 1,000 women aged 15-49 years; one of the highest in the world<a href="#accordion">[1]</a>.

The lack of education on such topics also means that both men and women are generally unaware of reproductive health issues. Moreover, the lack of knowledge and awareness of contraception increases the risk of teenage pregnancies, unplanned pregnancies, and unsafe abortions. Thus, resulting in poor health outcomes for both mother and child.&nbsp;

As per estimates, only 35% of married women of reproductive age in Pakistan, use some form of contraception<a href="#accordion">[1]</a>. Condoms are the most common method of contraception, followed by pills and withdrawal methods<a href="#accordion">[2]</a>. Although the use of oral contraceptive pills has increased over the years, there is still poor knowledge of the drug&#39;s effects. This lack of awareness can lead to the misuse of these medications, leading to adverse effects in at-risk individuals for e.g. women with existing cardiovascular disease (CVD) are often at a higher risk of these side effects.&nbsp;

Across Europe and the world, CVD accounts for a majority of deaths in women, while contrastingly in Pakistan, men and women are at an equal risk of coronary artery disease<a href="#accordion">[3]</a>. Due to the high prevalence, it is important that women are aware of the risks associated with using oral contraceptives with pre-existing heart conditions.&nbsp;

&nbsp;

Oral contraceptive pills (OCPs) are often the most popular option among users. They range in effectiveness from 89-99%. They are of two types: combined estrogen-progesterone and the progesterone-only pill. While both are a form of birth control, they can also be used for treating medical conditions such as endometriosis, <a href="https://www.merisehat.pk/disease/polycystic-ovary-syndrome-pcos">polycystic ovary syndrome (PCOS)</a>, and other menstrual disorders.

&nbsp;

1. Combined Oral Contraceptive (COC) - These contain a combination of the hormones, estrogen and progesterone that help prevent ovulation; thus, preventing pregnancy. The pills may contain the same dose of the hormones (monophasic), or varying weekly doses of both or either component (multiphasic). A single packet typically contains 21 pills that are taken over a 28-day period and 7 placebo pills for menstruating days. Although they have a generally safe profile, nausea, vomiting, weight gain, fluid retention, and bloating are common side effects of drug use. However, in some cases, they can also cause other severe side effects, such as:

<ul>
	<li>Increased risk of blood clots</li>
	<li>Hypertension</li>
	<li>Increased risk of stroke and myocardial infarction</li>
</ul>

These drugs are usually contraindicated in smokers and those older than 35 years of age.

&nbsp;

2. Progestin-Only Pill (POP) - Unlike COCs, these only contain a synthetic progestin. The lack of estrogen reduces the risk of adverse side effects such as thromboembolism, stroke, or cardiovascular diseases. However, it can cause breast tenderness, heavy bleeding, mood swings, anxiety, and weight gain among users. POPs are typically prescribed to women who cannot have COCs or estrogen-containing compounds.

3. Emergency Contraception Pill (ECP) - Also called the morning-after pill, it may contain higher doses of the hormone estrogen, progestin, or both. They help delay ovulation or fertilization and are commonly used following unprotected sexual intercourse or a condom breakage. However, they are not meant for regular birth control.

Understanding The Correct OCP For Heart Patients

Doctors usually prescribe contraceptive methods based on a patient&#39;s health and preference. As per current guidelines, doctors must weigh the risks and benefits for each patient prior to selection of contraception.&nbsp;

Women with cardiac disease are not only at a higher risk of maternal death during pregnancy, but also complications such as stillbirth, preterm delivery, or intrauterine growth restriction. Due to the high incidence of unplanned pregnancies, it is important that these women are counselled on effective and safe contraceptive options. Moreover, they are more likely to develop adverse effects to oral contraceptives. Therefore, caution is practiced when prescribing them pills or other contraceptive options.&nbsp;

OCP use among smokers older than 35 years of age is associated with a significantly higher risk of cardiovascular side effects such as deep vein thrombosis. As per estimates, such women have a ten-fold increased risk of myocardial infarction<a href="#accordion">[4]</a>. Therefore, women older than 35 are typically assessed for risk factors such as CVD, hypertension, diabetes, and kidney disease prior to use.&nbsp;

Compared to non-users, combined oral contraceptive users have a much higher risk of myocardial infarction and stroke. Moreover, women with pre-existing hypertension have a 9-16% chance of exacerbation when using OCPs<a href="#accordion">[4]</a>.

&nbsp;

Ideally, contraception is meant to be safe, effective, and protect against sexually transmitted infections. However, no one method can guarantee all three.&nbsp;

&nbsp;

<ul>
	<li>Barrier Methods - These methods are all safe for cardiac patients; however, they have a high failure rate. Therefore, should not be prescribed in cardiac patients to avoid pregnancies.&nbsp;</li>
	<li>Combined Oral Contraceptive Pill - Due to the estrogen component, COCs are associated with multiple risks to women with cardiovascular disease. Therefore, women with CVD risk factors and existing heart disease are not prescribed COCs.</li>
	<li>Progestin-Only Pill - In women with an increased risk of thromboembolism, POPs are usually the preferred option. They are generally considered safe for all CVD patients. However, they can interfere with warfarin metabolism and decrease its therapeutic role. Therefore, careful monitoring of INR is required in such patients.&nbsp;</li>
	<li>Depo-Provera Injection - These injectable contraceptives last 12 weeks and are very effective. However, discontinuation causes a rapid return to fertility. Moreover, it can put patients at risk of ischemic heart disease.</li>
	<li>Mirena Intra-uterine Device (IUD) - Although extremely effective, its insertion can induce a vasovagal reaction in 5% of patients, and lead to a cardiovascular collapse<a href="#accordion">[5]</a>. It is contraindicated in women with pulmonary vascular disease and those at high risk of endocarditis.&nbsp;</li>
	<li>Hormonal Implants - Subcutaneous progestogen implants are highly effective and work as a form of sterilization. Moreover, they have no cardiac contraindications.</li>
</ul>

&nbsp;

Conclusion

According to the Pakistan Demographic and Health Survey (PDHS), the current contraceptive prevalence rate (CPR) is only 34%<a href="#accordion">[6]</a>. There are several barriers to contraceptive use among Pakistani women of reproductive age. These range from religious factors, and lack of access to low socioeconomic status. Although oral contraceptive pills are commonly used as a form of birth control, there are a lot of misconceptions regarding infertility and weight gain that further limits their use.&nbsp;

The lack of dialogue around sexual and reproductive health has left a huge majority of Pakistani women unaware of their health condition and the best health options for their bodies. Moreover, in Pakistan, there is a high prevalence of cardiovascular diseases among women. This puts them at an even higher risk of pregnancy complications; thus, emphasizing the need for better contraceptive methods for these individuals.&nbsp;

Currently, progestin-only pills and hormonal implants are considered the most effective and safe contraceptive options for women with CVD. However, newer formulations of oral contraceptive pills with lower overall risk are being developed. These are expected to help lower blood pressure in users and prevent weight gain.&nbsp;

For now, the best method is to weigh all benefits and risks associated with a particular method before use. Moreover, women should be counseled on the various options available to them and the adverse effects associated with these options.&nbsp;

Key Points

<ul>
</ul>

<ul>
	<li>In Pakistan, only 35% of married women of reproductive age practice some form of contraception.</li>
	<li>The stigma surrounding sexual health has placed several barriers for women to access safe contraception methods in the country.</li>
	<li>The lack of awareness of various contraceptive methods has led to an increase in abortions and sexually transmitted infections among the younger population.</li>
	<li>Due to their overall safety profile, easy availability, and high effectiveness oral contraceptive pills are mostly prescribed to women. The two common oral contraceptives include the progestin-only pill and the combined oral pill.</li>
	<li>Despite the overall safety profile, OCPs can increase the risk of several side effects, especially among women with a cardiovascular disorder.</li>
	<li>Women with existing cardiac disease are at a higher risk of maternal death during pregnancy, and complications such as preterm birth, growth restriction, and stillbirth. Therefore, there is a greater need for safe and effective contraceptive methods for these high-risk individuals.&nbsp;</li>
	<li>COCs increase the risk of stroke, thromboembolism, and myocardial infarctions. Therefore, they are contraindicated in smokers above 35 years of age and women with CVD risk factors or existing cardiac disease.</li>
	<li>POPs and hormonal implants are generally considered safe and effective in cardiac patients.</li>
	<li>Newer contraceptive pills are being developed that are expected to have a lower overall risk for cardiac patients.</li>
</ul>
