As most people are born with a healthy heart they tend to think they have years before they need to worry about heart problems.1a However, complications can occur at any age – all the more reason to give your heart the support it deserves.1b

Located centrally in your chest, between your lungs, leaning slightly to the left, your heart is approximately the size of your clenched fist.2 If you gently press down on an artery anywhere under your skin, on your neck or just under your thumb on the inside of your wrist for example, you can feel your pulse or heart ‘beat’. 3a Your heart beat is in fact the muscular walls of your heart contracting (squeezing) non-stop, keeping you alive by pumping blood throughout your body.3b This is important for supplying the oxygen and nutrients your body needs to work properly.3c
Each day, your heart beats approximately 115 000 times and pumps approximately 2 000 gallons of blood.4

Cardiovascular disease is a general term for conditions affecting the heart (cardio) or blood vessels (vascular). When people speak of heart disease they usually mean coronary heart disease.

Your heart needs oxygen to work properly. Coronary heart disease is a condition where the flow of oxygen-rich blood to your heart is blocked or reduced, putting increased strain on your heart, which can trigger:5a
  • Angina – chest pain from restricted blood flow to your heart
  • Heart attack – when the blood flow to your heart is suddenly blocked
  • Heart failure – when your heart muscle fails to pump blood around your body properly5b

When most people think of signs of heart trouble they think of chest pain, which is the most obvious warning sign. However, your first symptom might not be a pain in your chest. In some cases, heart trouble such as a heart attack, can occur without an obvious warning sign. 1c, 6a WHAT TO LOOK OUT FOR
  • Chest pain, heaviness, tightness, pressure, a pinching or burning sensation
  • Pain in your shoulders and arms, particularly down your left arm, throat, jaw or back
  • Shortness of breath from small bursts of activity that do not usually make you breathless
  • Swollen hands, legs, feet or ankles
  • Excessive tiredness even though you have not changed your usual routine
  • Nausea, indigestion, heartburn, or stomach pain not caused by something you ate
  • Lightheadedness or dizziness where you suddenly feel unsteady on your feet
  • Sweating, feeling clammy and hot together with chest pains – not from physical exercise
  • Dry or persistent cough, or a wheezing, restricted or choking sensation in your throat
  • Irregular heart beat particularly if your heart beats rapidly and feels as though it is jumping around6b, 7
  • Snoring loudly resulting in a gasping or choking could be a sign of sleep apnea – a condition that occurs while asleep when you stop breathing momentarily at different times of the night
