Presentation

Dressler syndrome was historically a phenomenon complicating about 7% of myocardial infarctions, but in the era of percutaneous coronary intervention, it is very uncommon. The disease consists of a persistent low-grade

Diagnosis

Differential diagnosis

Dressler syndrome needs to be differentiated from pulmonary embolism, another identifiable cause of pleuritic (and non-pleuritic) chest pain in people who have been hospitalized and/or undergone surgical procedures within the preceding weeks. ischaemic heart disease.

Treatment

Dressler syndrome is best treated with high dose aspirin. In some resistant cases,

corticosteroids Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones. Two main classes of corticosteroids, glucocorticoids and mineralocorticoids, are involve ...

can be used but are not preferred (avoided) in first month due to the high frequency of impaired ventricular healing leading to increased rate of ventricular rupture. Other NSAIDs, though once used to treat Dressler syndrome, are less advocated and should be avoided in patients with ischemic heart disease. One NSAID in particular, indomethacin, can inhibit new collagen deposition, thus impairing the healing process for the infarcted region. Other NSAIDS should be used only in cases refractory to aspirin. Heparin should be avoided because it can lead to hemorrhage into the pericardial sac, leading to tamponade. The only time heparin could be used with pericarditis is with coexisting acute MI, in order to prevent further thrombus formation.
