Heart disease remains the leading cause of death worldwide, affecting millions of people each year. While some symptoms are dramatic and obvious, others are more subtle — but no less serious. At Complete Cardiology, we believe that early detection saves lives. Recognising the early warning signs of heart disease can make all the difference in preventing a major cardiac event. That’s why it’s essential to be aware of heart disease symptoms you should never ignore, such as chest discomfort, shortness of breath, fatigue, or irregular heartbeat—each could be a crucial clue your heart is in trouble.

Heart disease symptoms

In this post, we’ll explore the  symptoms, what they might mean, and when it’s time to seek professional care.

  • Chest Pain or Discomfort

    Perhaps the most well-known sign of a heart problem, chest pain (also known as angina) can feel like pressure, squeezing, fullness, or pain in the center of the chest. It often occurs during physical activity or stress and goes away with rest. However, any chest discomfort should be evaluated immediately, as it could indicate a blocked artery or an impending heart attack.

  • Shortness of Breath

    If you feel winded after climbing a flight of stairs or during activities that used to be easy, it could be more than just aging or being out of shape. Shortness of breath — especially when it’s sudden or persistent — might be a sign that your heart isn’t pumping efficiently, leading to a backup of fluid in the lungs.

  • Fatigue or Unusual Tiredness

    Unexplained, persistent fatigue can be a symptom of heart failure or coronary artery disease. If you’re feeling constantly drained despite getting enough sleep and nutrition, it’s worth checking in with a cardiologist.

  • Pain in the Neck, Jaw, or Arm

    Heart-related pain isn’t always confined to the chest. Sometimes, pain radiates to the left arm, neck, jaw, back, or even the stomach. These symptoms are more common in women and can easily be mistaken for other issues — but they’re often associated with heart attacks or angina.

  • Irregular Heartbeat or Palpitations

    An occasional flutter is usually harmless, but if you’re experiencing frequent irregular heartbeats, fluttering, or pounding in the chest, it might be a sign of arrhythmia, which can increase your risk of stroke or heart failure if left untreated.

  • Swelling in Legs, Ankles, or Feet

    When the heart can’t pump blood effectively, it can lead to fluid build-up, especially in the lower extremities. This swelling, or oedema, might also be accompanied by weight gain and difficulty breathing.

  • Dizziness or Light headedness

    Feeling dizzy or fainting could be a sign of a serious heart rhythm issue or even a valve problem. It might also indicate low blood pressure caused by heart failure or blocked arteries.

  • Cold Sweats and Nausea

    If you’re breaking out in a cold sweat or experiencing nausea and vomiting — especially combined with chest pain — don’t wait. These are common, but often overlooked, signs of a heart attack, particularly in women.
