Heart disease does not always announce itself with dramatic chest pain. In many people in Nigeria, the first signs are quiet: tightness after climbing stairs, breathlessness at night, or tiredness that does not go away. Knowing these signs and acting early can protect your life.

This guide explains seven heart warning signs, what they feel like, and when to see a cardiac doctor in Kano or seek immediate medical attention at a dedicated cardiology hospital in Kano.

The 7 Heart Warning Signs You Should Never Ignore

1. Chest Pain, Pressure or Tightness

This is the best-known sign. It may feel like a heavy weight, squeezing, fullness or burning in the centre or left of the chest. It can start during physical activity, such as walking fast, and ease with rest, or it can come on suddenly at rest.

Chest pain that lasts more than a few minutes or keeps returning should always be checked. It is easy to mistake heart pain for heartburn, so do not try to determine the cause at home.

2. Shortness of Breath

Do you get breathless doing things that used to be easy, like climbing a flight of stairs or walking to the market? Breathlessness can indicate that the heart is not pumping effectively.

Waking up at night gasping for air or needing extra pillows to breathe comfortably when lying down is another warning sign that requires medical assessment.

3. Pain That Spreads to the Arm, Jaw, Neck or Back

Heart pain does not always stay in the chest. It can travel to the left arm, both arms, the shoulder, neck, jaw or upper back.

Pain in these areas accompanied by chest discomfort or breathlessness should be treated as a medical emergency.

4. Cold Sweat, Nausea or Dizziness

Breaking into a cold sweat for no clear reason, feeling sick, vomiting or feeling light-headed can occur during a heart attack.

These signs can be mistaken for problems caused by food or hot weather, but they are especially concerning when they appear alongside chest discomfort or breathlessness.

5. A Racing, Pounding or Irregular Heartbeat

Everyone notices their heartbeat after exercise or fright. However, a heart that races, flutters, skips beats or pounds for no apparent reason may indicate a heart rhythm problem.

Fainting or nearly fainting alongside palpitations requires urgent medical assessment.

6. Swelling of the Feet, Ankles or Belly

When the heart cannot pump effectively, fluid can build up in the body. Look for swollen feet and ankles that leave a dent when pressed, a swollen belly or sudden weight gain over a few days.

These symptoms, particularly when accompanied by breathlessness, may indicate heart failure and should be assessed by a doctor.

7. Unusual or Extreme Tiredness

Feeling drained after ordinary activity or remaining tired for days without an obvious reason can sometimes be an early sign of heart trouble.

Women, older adults and people with diabetes may experience a heart attack with few or no typical chest symptoms. They may instead experience unusual tiredness, nausea or discomfort in the back, jaw or stomach.

What to Do if You Suspect a Heart Attack

  • Seek emergency medical help immediately: Contact the nearest emergency unit or arrange immediate transport to a hospital.
  • Do not drive yourself: Ask someone to take you to the nearest emergency department.
  • Sit down and rest: Avoid physical exertion while waiting for medical help.
  • Do not take medicine on your own: Do not take aspirin or other medicines unless a doctor or qualified emergency medical professional advises you to.
  • Do not wait to see if the symptoms pass: Early treatment can help limit heart damage, and every minute counts.
If you suspect a heart attack, seek immediate medical attention rather than waiting for symptoms to improve.

Who Is at Higher Risk of Heart Disease?

You may be more likely to develop heart problems if you have any of the following risk factors:

  • High blood pressure: It is a leading risk factor for heart disease and often causes no noticeable symptoms. Have your blood pressure checked regularly.
  • Diabetes: High blood sugar can damage blood vessels over time.
  • High cholesterol: Elevated cholesterol can contribute to plaque buildup in the arteries.
  • Smoking: Tobacco use and regular exposure to tobacco smoke increase cardiovascular risk.
  • Overweight or physical inactivity: Excess weight and a sedentary lifestyle can increase the risk of heart disease.
  • A family history: Heart disease, stroke or sudden cardiac death in close relatives can increase your risk.
  • Age: Cardiovascular risk generally rises with age, although younger adults can also develop heart problems.

High blood pressure also raises the risk of stroke. Recognising stroke warning signs and seeking emergency care promptly are equally important.

When to See a Heart Specialist in Kano

Do not wait for a medical emergency before seeking advice. Consider booking an appointment with a cardiac doctor in Kano if you experience:

  • Chest discomfort, even if it comes and goes.
  • Breathlessness during mild activity or waking up at night short of breath.
  • Palpitations, dizziness or fainting.
  • Swollen feet or ankles.
  • High blood pressure or diabetes that is difficult to control.
  • A close relative who developed heart disease at a young age.
  • Questions about managing heart medication during fasting or before starting strenuous exercise.

If you experience sudden or severe chest pain, severe breathlessness or other possible heart attack symptoms, seek emergency medical attention immediately.

What to Expect at a Cardiology Visit

During a cardiology appointment, the doctor will ask about your symptoms, family history, medicines and lifestyle. They may also check your blood pressure, pulse and heart sounds.

Depending on your symptoms and medical history, the doctor may recommend tests such as:

  • ECG: Records the electrical activity of your heart.
  • Holter monitoring: Records your heart rhythm over an extended period to help identify intermittent irregularities.
  • Blood tests: Help assess relevant health indicators and potential causes of symptoms.
  • Additional heart or imaging tests: Recommended when necessary based on your clinical assessment.

Bring a list of your current medicines and any previous test results to your appointment.

Premix Hospital's diagnostic centre lists ECG, Holter heart-rhythm monitoring and laboratory services. Contact the hospital to confirm test availability and appointment arrangements.

How to Protect Your Heart

  • Check your blood pressure and blood sugar regularly, even when you feel well.
  • Eat a balanced diet with vegetables, fruit, beans and whole grains, while reducing excess salt, fried foods and sugary drinks.
  • Stay physically active. Regular moderate activity, such as brisk walking, can support heart health. Ask your doctor what level of exercise is appropriate for you.
  • Avoid smoking and limit alcohol consumption.
  • Manage stress and get adequate sleep.
  • Take prescribed medicines as directed. Do not stop blood pressure or heart medication without consulting your doctor.
  • Attend regular health checkups, particularly if you have risk factors or a family history of heart disease.

For routine medical assessments, visit the general medicine department.

Frequently Asked Questions

What Are the Warning Signs of a Heart Problem?

Common warning signs include chest pain or pressure, shortness of breath, pain spreading to the arm, jaw, neck or back, cold sweats with nausea or dizziness, an irregular heartbeat, swelling of the feet or ankles, and unusual tiredness.

Can a Heart Attack Happen Without Chest Pain?

Yes. Some people, especially women, older adults and people with diabetes, may experience breathlessness, nausea, extreme tiredness or discomfort in the jaw, back or stomach without typical chest pain.

How Do I Know if Chest Pain Is Heartburn or a Heart Problem?

You cannot reliably distinguish between them at home. Heartburn often causes a burning sensation behind the breastbone after meals, but heart-related pain can feel similar. If chest pain is new, severe, lasts more than a few minutes or occurs with breathlessness, sweating or pain spreading to the arm or jaw, seek emergency medical attention.

Is High Blood Pressure a Sign of Heart Disease?

High blood pressure is a major risk factor for heart disease and stroke. It often causes no symptoms, so regular blood pressure checks are important even when you feel well.

When Should I See a Heart Specialist in Kano?

Consult a heart specialist if you experience repeated chest discomfort, breathlessness during mild activity, palpitations, fainting or swollen ankles, or if you have a family history of heart disease. Seek emergency care immediately if symptoms are sudden or severe.

What Should I Do if Someone Has a Suspected Heart Attack?

Seek emergency medical help immediately or arrange prompt transport to the nearest emergency department. Keep the person resting, avoid unnecessary movement and do not give medication unless advised by a qualified medical professional.
