Which patient demographic is most commonly affected by pericarditis?

Pericarditis is most commonly seen in men under the age of 50. This demographic is particularly at risk for this condition due to a combination of factors that include a higher prevalence of idiopathic and viral causes of pericarditis in younger males. The condition can occur secondary to infectious processes, autoimmune diseases, or post-myocardial infarction, which are more frequently diagnosed in this age group.

Men under 50 are also more likely to experience pericarditis following a recent viral infection, such as those caused by Coxsackie virus or echovirus, both of which have a notable incidence in younger populations. Furthermore, factors such as lifestyle and occupational hazards can contribute to the development of pericarditis in this demographic.

In contrast, while older adults and women over 60 may experience pericarditis, it is typically less common in these groups, especially when considering the idiopathic and viral forms of the disease. Children also have a lower incidence, with pericarditis in that age group often associated with systemic illnesses rather than primary idiopathic causes. Therefore, men under 50 reflect the most commonly affected demographic for pericarditis, emphasizing the need for awareness and early diagnosis in this specific population.
