Coronary heart disease
Table of Contents
Key takeaways
- Coronary heart disease happens when the arteries that supply the heart muscle become narrowed by fatty material. It is a major cause of angina, heart attacks and heart failure. Women may experience chest discomfort, breathlessness, fatigue, nausea or pain in the jaw, back or arm, and symptoms can be misattributed to indigestion, anxiety or menopause, so assessment matters.
- The process usually starts with atherosclerosis. Cholesterol-rich plaque builds up inside artery walls, inflammation makes plaques less stable, and blood flow to the heart muscle can become limited. Stable narrowing can cause angina during exertion. If a plaque ruptures, a clot can form suddenly and block the artery, causing a heart attack. Blood pressure, smoking, diabetes and high cholesterol accelerate this process.
- Assessment matters because similar symptoms can have different causes, and treatment should be matched to the confirmed diagnosis and personal risk factors.
- Call 999 for chest pain or tightness that is severe, lasts more than a few minutes, occurs with breathlessness, sweating, nausea, collapse, or spreads to the arm, jaw, neck or back. Use NHS 111 for urgent advice for new exertional chest symptoms or palpitations, but do not delay emergency care when heart attack symptoms are possible.

Overview
Coronary heart disease happens when the arteries that supply the heart muscle become narrowed by fatty material. It is a major cause of angina, heart attacks and heart failure. Women may experience chest discomfort, breathlessness, fatigue, nausea or pain in the jaw, back or arm, and symptoms can be misattributed to indigestion, anxiety or menopause, so assessment matters.
The process usually starts with atherosclerosis. Cholesterol-rich plaque builds up inside artery walls, inflammation makes plaques less stable, and blood flow to the heart muscle can become limited. Stable narrowing can cause angina during exertion. If a plaque ruptures, a clot can form suddenly and block the artery, causing a heart attack. Blood pressure, smoking, diabetes and high cholesterol accelerate this process.
This article is written as a practical medical guide rather than a short definition. It covers what the condition may feel like, why it happens, which risk factors are relevant for women and families, how clinicians assess it, what treatment may involve, and when symptoms should be escalated. The aim is to support informed conversations with a GP, pharmacist, specialist clinician or emergency service, not to replace individual assessment.
Symptoms and reader concerns
Symptoms can vary in intensity, duration and impact. Some people have a clear textbook pattern, while others have subtle, overlapping or intermittent symptoms. Keep track of timing, triggers, severity, medicines, pregnancy or menopause context where relevant, and how symptoms affect sleep, work, sex, caring responsibilities or exercise.
- chest pressure, tightness, heaviness or pain, often triggered by exertion or stress.
- pain or discomfort spreading to the arm, jaw, neck, back or upper abdomen.
- breathlessness, sweating, nausea, light-headedness or unusual fatigue.
- symptoms that appear with activity and settle with rest, which may suggest angina.
- silent or atypical symptoms, especially in diabetes, older age and some women.
Symptoms that are new, persistent, one-sided, severe, linked with bleeding, breathing difficulty, fainting, pregnancy, neurological changes or rapid deterioration should be assessed promptly. It is also worth seeking help when symptoms keep returning despite reasonable self-care, because repeated episodes may indicate an underlying cause that needs targeted treatment.
Causes and risk factors
The underlying mechanism is important because it guides safe treatment. The process usually starts with atherosclerosis. Cholesterol-rich plaque builds up inside artery walls, inflammation makes plaques less stable, and blood flow to the heart muscle can become limited. Stable narrowing can cause angina during exertion. If a plaque ruptures, a clot can form suddenly and block the artery, causing a heart attack. Blood pressure, smoking, diabetes and high cholesterol accelerate this process.
Risk factors do not mean someone has caused the condition. They simply help clinicians decide what to ask about, what to test, what complications to consider and which prevention steps are realistic.
- smoking, high blood pressure, high cholesterol and diabetes.
- family history of early heart disease, chronic kidney disease or inflammatory conditions.
- pregnancy complications such as pre-eclampsia or gestational diabetes, which can indicate future cardiovascular risk.
- early menopause, polycystic ovary syndrome or other hormone-related risk patterns.
- low physical activity, excess alcohol, poor sleep, long-term stress and socioeconomic factors that influence health access.
Women may also need context-specific review around heavy periods, pregnancy and birth, contraception, hormone therapy, menopause timing, pelvic symptoms, autoimmune disease or previous cancer treatment. Those details can change both the likely cause and the safest management options.
Diagnosis and assessment
Assessment may include blood pressure, cholesterol, diabetes checks, ECG, blood tests, exercise or imaging tests, CT coronary angiography or specialist cardiology review. Suspected heart attack is assessed urgently with ECG and troponin blood tests. Coronary symptoms should not be self-diagnosed as reflux, panic or muscle strain when they are new, exertional or associated with breathlessness, sweating or nausea.
A useful appointment history includes when symptoms started, whether they are improving or worsening, what has already been tried, current medicines and supplements, allergies, relevant family history and any red flags. If symptoms affect intimate health, bowel habits, periods, fertility, pregnancy or mental wellbeing, it is appropriate to say so clearly; these details are clinical information, not personal failings.
Testing should be proportionate. Some conditions are diagnosed mainly from symptoms and examination, while others need blood tests, imaging, swabs, endoscopy, ultrasound or specialist referral. If a test result is normal but symptoms continue, follow-up can still be appropriate because a single test rarely answers every clinical question.
Treatment and management
Management aims to reduce symptoms and lower the risk of heart attack and stroke. It may include smoking cessation support, blood pressure and cholesterol management, diabetes care, antiplatelet or anti-anginal medicines, cardiac rehabilitation, and procedures such as angioplasty or bypass surgery for selected people. Treatment choice depends on symptoms, anatomy, risk, other conditions and personal preferences discussed with a clinician.
Good management balances symptom relief with safety. Medicines, procedures and monitoring can be helpful, but they should be chosen with the confirmed diagnosis, medical history, pregnancy or breastfeeding status, other medicines and personal preferences in mind. Ask what benefit is expected, how quickly improvement should be noticed, what side effects to watch for, and what to do if symptoms do not improve.
For longer-term conditions, follow-up is part of care rather than a sign that treatment has failed. Reviews can check whether the diagnosis still fits, whether complications are developing, whether medicines remain suitable, and whether additional support such as physiotherapy, dietetic input, psychological support, specialist nursing or consultant review is needed.
Self-care and prevention
Self-care is powerful but should sit alongside medical review. A heart-healthy pattern includes not smoking, regular movement suited to ability, Mediterranean-style eating, managing blood pressure, cholesterol and diabetes, limiting alcohol, sleep support and taking prescribed medicines consistently. Women with early menopause, pregnancy complications or strong family history should discuss cardiovascular risk assessment rather than waiting for symptoms.
Prevention advice should be realistic and evidence-informed. It may reduce risk or symptom burden, but it should not be framed as a personal responsibility to prevent every flare, complication or recurrence. If recommended self-care is unaffordable, impractical or clashes with work, disability, caring responsibilities or cultural needs, discuss alternatives with a clinician or pharmacist.
Avoid relying on unverified home remedies for persistent or severe symptoms. Some products can irritate skin, interact with medicines, delay diagnosis or be unsuitable in pregnancy, breastfeeding, kidney disease, liver disease, diabetes or when taking anticoagulants. Pharmacy advice can be a useful first step for mild symptoms, but it has limits when red flags are present.
When to seek medical advice
Call 999 for chest pain or tightness that is severe, lasts more than a few minutes, occurs with breathlessness, sweating, nausea, collapse, or spreads to the arm, jaw, neck or back. Use NHS 111 for urgent advice for new exertional chest symptoms or palpitations, but do not delay emergency care when heart attack symptoms are possible.
Bring a list of medicines, supplements, allergies and relevant diagnoses to appointments. If symptoms are intermittent, photographs, home readings, a diary or a written timeline can help, provided this is safe and does not delay urgent care. If you feel dismissed and symptoms are worsening or affecting daily life, asking for review or a second opinion is reasonable.
