The heart is a muscular pump roughly the size of a fist, divided into four chambers with valves ensuring one-way blood flow.
Oxygen-poor blood enters the right side, travels to the lungs for oxygenation, then returns to the left side to be pumped around the body via the aorta.
The heart has its own blood supply through the coronary arteries.
These basic facts underpin much clinical negligence work involving cardiac events, because delays or errors in recognising when the pump or its supply is failing can cause serious harm.
Women’s hearts are, on average, smaller than men’s, with narrower coronary arteries and differences in muscle structure and function.
These are not simply scaled-down versions of a male heart; the architecture and physiology differ in ways that influence how disease presents and progresses.
During pregnancy the heart works harder: blood volume and cardiac output rise significantly to support the growing baby and placenta. After birth the heart must adapt again. These transitions can unmask or trigger problems such as peripartum cardiomyopathy or spontaneous coronary artery dissection (SCAD), a tear in a coronary artery wall that is far more common in women, especially around pregnancy and the early postpartum period.
Recognising when something is wrong
Classic “crushing chest pain radiating to the left arm” is real for many people, but women frequently experience additional or different symptoms: sudden fatigue, nausea, indigestion-like discomfort, jaw or neck pain, shortness of breath, back pain or a general sense of feeling unwell. Research and patient reports show these can be dismissed or attributed to anxiety, reflux or stress, particularly in younger women or those without obvious risk factors.
British Heart Foundation data confirm coronary heart disease remains a leading cause of death for women in the UK, killing more women than breast cancer.
Your rights and what good care looks like
Under the principles established in Montgomery v Lanarkshire Health Board [2015] UKSC 11, clinicians must discuss material risks and reasonable alternatives in a way that enables you to make an informed choice.
For women of reproductive age this includes discussing how a proposed test, medication or procedure might affect future pregnancies or interact with hormonal changes.
You are entitled to have your symptoms taken seriously and investigated appropriately, even if they do not match the “typical” picture.
If investigations such as ECG, blood tests (troponin) or imaging are declined or delayed without clear explanation, or if concerns you raise about feeling unwell in pregnancy or after birth are not escalated, that may warrant further questions.
When care falls short
Clinical negligence claims in cardiac cases often involve allegations of missed or delayed diagnosis of acute coronary syndromes, failure to recognise pregnancy-related cardiac complications, or inadequate fetal monitoring during labour when maternal condition affects the baby.
In birth injury cases the cardiotocograph (CTG) trace recording the baby’s heart rate is frequently central evidence; abnormal patterns indicating possible lack of oxygen require timely action.
The patient-focused article on maternity safety and the page on informed consent explore these issues in more depth.
Practical steps
- Keep a simple symptom diary (timing, what you were doing, associated feelings).
- Ask directly: “Could this be my heart? What tests would rule that out?” and “How might this treatment affect a future pregnancy?”
- Request a second opinion or referral to a cardiologist with experience in women’s heart health or pregnancy cardiology if symptoms persist.
- In an emergency, state your symptoms clearly and ask for cardiac assessment.
Early recognition and appropriate response save lives and reduce long-term harm. Many women describe having to advocate persistently; systems should make that unnecessary.
