What is heart disease?

Heart disease is the name for a range of conditions that affect the structure and function of the heart and blood vessels. It includes coronary heart disease, heart failure, valve disease, arrhythmias and blood vessel diseases.  

  • heart attack occurs when a coronary artery blocks or narrows because of a build-up of fatty plaque.  

  • Heart failure: is a long-term condition where your heart muscle doesn’t pump blood to the rest of your body the way it should.  

  • Valve disease: if you have heart valve disease it means your heart’s valves don’t open or close properly.   

  • Rheumatic Heart Disease (RHD): if you have had acute rheumatic fever (ARF), this can cause swelling and damage to the valves of your heart leading to RHD.  

  • Arrythmias:is a fault in the heart’s electrical system, which affects your heart’s pumping rhythm.
