In this video, we talk about a commonly performed blood test that is used to measure a protein called Troponin. This is an integral part of how our heart muscle works and is released from the heart at times of stress or damage to the heart tissue. The released protein can be detected by a simple blood test and is a useful way of helping to differentiate the causes of particular cardiac symptoms e.g. chest pain, shortness of breath, palpitations. Always remember that Heart Matters is all about general information only, for any specific health advice please consult your local health care professional.
