Key facts

Causes
Main causes
- Coronary artery disease (narrowing of the heart's blood vessels)
- High blood pressure (hypertension) damaging arteries and the heart
- Heart valve problems (leaking or narrowing)
- Heart muscle disease (cardiomyopathy) – weakened or thickened heart muscle
- Arrhythmias – electrical system problems causing irregular heartbeats
Risk factors
- Smoking
- Diabetes
- High cholesterol
- Obesity or being overweight
- Lack of physical activity
- Unhealthy diet high in salt, fat, and sugar
- Excess alcohol or drug use
When to see a doctor
See a doctor urgently if:
- Call emergency services for any symptoms in the emergency list above
- If you have ongoing chest pain that does not go away after a few minutes
Book a routine appointment if:
- Follow up with your doctor for regular check-ups, usually every 3–12 months
- Anytime your symptoms change or new symptoms appear
- Before making major changes to diet or exercise
Diagnosis
Your doctor will take a detailed medical history, listen to your heart, and order tests to understand your condition. Diagnosis often involves several steps.
Tests that may be done
- Blood tests (to check heart enzymes, cholesterol, blood sugar)
- Electrocardiogram (ECG) – records your heart's electrical activity
- Echocardiogram – an ultrasound to see your heart's structure and function
- Stress test – monitors your heart while you walk on a treadmill or take medication
- Ambulatory monitoring (Holter monitor) – wears a portable ECG for 24–48 hours
What to expect at your appointment
Diagnosis may take time. You may need multiple visits and tests. Your doctor will explain each test's purpose and what the results mean. Keep a list of your symptoms and questions to share.
Treatment
Treatment aims to improve your heart function, manage symptoms, and reduce the risk of future problems. It often includes a combination of lifestyle changes, medications, and sometimes procedures or surgery.
Self-care at home
- Follow a heart-healthy diet low in salt, saturated fat, and added sugars
- Get regular physical activity as advised by your doctor (e.g., walking, swimming)
- Quit smoking and avoid second-hand smoke
- Limit alcohol to no more than recommended guidelines
- Manage stress with relaxation techniques or counselling
Medical treatments
Your doctor may prescribe medications to lower blood pressure, reduce cholesterol, control heart rate, prevent blood clots, or reduce fluid build-up. These are part of a lifelong treatment plan. Always take medicines exactly as prescribed and discuss any side effects with your healthcare team.
When is surgery considered?
Surgery may be recommended if your condition is severe. Examples include coronary artery bypass grafting (CABG) to bypass blocked arteries, heart valve repair or replacement, or implantation of a pacemaker or defibrillator. Your doctor will discuss the benefits and risks.
Living with this condition
Living with a heart condition means monitoring your symptoms, taking medications regularly, and attending check-ups. Many people adjust well and keep up with work, hobbies, and family.
Lifestyle tips
- Keep a heart diary to track symptoms and triggers
- Learn to listen to your body – rest when you need to
- Attend cardiac rehabilitation programs if offered
- Stay socially connected – isolation can worsen health
Diet and exercise
Eat plenty of fruits, vegetables, whole grains, and lean proteins. Limit red meat, processed foods, and salty snacks. Aim for at least 150 minutes of moderate exercise each week, but start slowly and get medical advice first.
Mental health and emotional wellbeing
Depression and anxiety are common after a heart diagnosis. It's important to talk about your feelings with loved ones or a professional. Many people find support groups helpful.
Prevention
While you cannot always prevent a heart condition, you can slow its progression and reduce complications by managing risks like blood pressure, cholesterol, and blood sugar, and by adopting a healthy lifestyle.
Vaccines
Get the annual flu vaccine and pneumonia vaccine as recommended by your doctor, since heart patients are at higher risk for these infections.
Screening programmes
Regular blood pressure checks, cholesterol tests, and diabetes screening are important to catch changes early. Follow your doctor's schedule.
Complications
If left untreated
- Heart failure – the heart cannot pump enough blood
- Arrhythmias that can cause fainting or stroke
- Heart attack or worsening chest pain
- Blood clots leading to stroke or pulmonary embolism
Long-term outlook
With proper treatment and self-care, most people with a heart condition can expect to live many more years. Many return to normal activities and enjoy a good quality of life. Your healthcare team will help you manage the condition and adjust your plan as needed.
