Z82.4: Family history of ischaemic heart disease and other diseases of the circulatory system

The code Z82.4 refers to a family history of ischaemic heart disease and other diseases of the circulatory system. In simple terms, this means that one or more close relatives of the individual have had conditions related to inadequate blood supply to the heart or other problems affecting blood flow throughout the body. Having a family history of such conditions can increase a person's own risk of developing similar health issues. Ischaemic heart disease, for example, may include conditions such as heart attacks or angina, whereas other circulatory system diseases encompass a range of conditions from high blood pressure to stroke. These conditions usually develop over time due to factors such as unhealthy lifestyle and aging, and can present with symptoms including chest pain, shortness of breath, or fainting. However, they may also occur without any noticeable symptoms, especially in their early stages.
