Acute pericarditis: etiology, treatment and prognosis. A study of 115 patients

One hundred and 15 hospitalized patients with acute pericarditis were analyzed retrospectively for their etiology, management and long-term prognosis. It was found that most of the patients had either idiopathic or viral etiologies (60%), collagen disease (16.4%) or malignancy (6.9%). Most of the patients were treated with non-steroidal anti-inflammatory drugs (NSAID). Twenty-six patients (22%) required corticosteroids following NSAID treatment failure. Only one patient underwent pericardiocentesis for tuberculous pericarditis. The long-term prognosis was good, although 21.9% of the patients suffered from recurrent episodes of pericarditis. It is concluded that in hospitalized patients with pericarditis, an extensive workup may not reveal the major etiologies, and the disease may be more complicated than previously thought.
