Complications and prognosis
- Prognosis of pericarditis depends on its cause. Idiopathic pericarditis is often self-limited and most people recover in 2 weeks to 3 months. Idiopathic or viral pericarditis often have a good long term prognosis[1]with few developing recurrences[2]. Approximately 15-30% of patients with idiopathic acute pericarditis who are not treated with colchicine develop recurrence.
- However, the condition can be complicated by significant fluid buildup around the heart, a condition known as a pericardial effusion. If the fluid accumulates too rapidly or is too large, then (cardiac tamponade), a condition in which the heart is compressed by the fluid and cannot pump enough blood forward may occur. Cardiac tamponade may require urgent intervention including pericardiocentesis. This is common in patients with a specific underlying etiology such as malignancy, tuberculosis[3], or purulent pericarditis and rarely occurs in idiopathic pericarditis.
- Post MI pericarditis is usually associated with large infarcts. Therefore have overall poor long term prognosis.
- In penetrating injuries, pericardial effusion and tamponade may rapidly develop. Early detection and treatment of cardiac tamponade has good prognosis. Minor perforations, isolated right ventricular wounds, systolic blood pressure more than 50 mm Hg have better outcomes.
- Pericarditis associated with scleroderma, rheumatic fever, purulent, tuberculosis, or malignancy have complicated courses with worse outcomes. Mortality rate of tuberculous pericarditis in preantibiotic era was 80-90%[4]. Mortality rate currently is 8-17%[5][6] and 17-34% if associated with HIV[7].
- Patients with renal failure are associated with significant morbidity and may develop hemorrhagic pericarditis[8]
- If scarring of the sac around the heart (the pericardium) occurs, then this is called constrictive pericarditis which may require surgical stripping of the scar.
