It’s when fatty deposits build up in your coronary arteries (aka very important arteries!), making them narrower and therefore reducing blood flow to the heart muscle. This is bad news. Less blood flow means less oxygen to the heart’s muscles, so less aerobic respiration. This means that the poor heart has to work extra hard to get energy! High blood pressure puts extra pressure on the arteries walls, making them even more susceptible to narrowing. This happens because if your blood pressure is too high, the muscles in the artery need to respond by pushing back harder and so they become more muscular and so there is less space for blood to flow through. Combined with coronary heart disease, this can lead to heart attacks, or worse, death. Well, there are a number of factors, including age, smoking, diet and physical activity. The older you are and the more you smoke, the higher the chances. Diet and physical activity also have a big effect on blood pressure, as well as cholesterol, and weight - all of which are risk factors of coronary heart disease. [...] If someone’s heart is seriously damaged, they’ll need a new one. This is known as a transplant. This is done by removing their heart, and connecting the new one to the aorta and the pulmonary artery. Can you spot the potential problem in this process? Pause the video and have a think. Whilst surgery is going on, the patient won’t have a heart! This is solved by connecting the patient to a heart-lung bypass machine, which takes over the job of the heart and lungs. So there we have heart disease, the treatments and their risks.
