OBJECTIVE: We analyzed the frequency of peripheral embolisms, the underlying heart disease,triggering factors, the sites of the emboli, and evolution of the patients. METHODS: We analyzed 29 cases of peripheral arterial embolism out of a total of 20,211 hospitalizations in a cardiology center in the city of São Paulo. The age was 51.89±18.66 years, and 15 were males. RESULTS: Embolism in the right lower limb occurred in 18 patients (62.0%),in the left lower 11(37.9%) and right upper 3 (10.3%) limbs, and in the left arm (1). Four patients had embolism in two limbs. The heart disease, mitral valvar heart disease (9 patients - 31.0%); infective endocarditis (7- 24.1%); dilated cardiomyopathy (6 - 20.6%); ischemic coronary heart disease (6 patients - 20.6%); and one patient with cor pulmonale. Atrial fibrillation was observed in 20 patients (68.9%), chronic in 12 patients (41.3% ) and acute in 8 (27.5%). All patients with mitral valvar heart disease had atrial fibrillation, chronic in 8 patients (88.8%); patients with cardiomyopathy and coronary heart disease, 4 in each group had atrial fibrillation, acute in 60% of the patients.Patients with infective endocarditis, 3 had staphylococcus and 2 Gram-negative bacteria. In the follow-up, 2 patients (6.8%) required limbs amputation, and 5 (17.2%) died due to embolism. CONCLUSION: Most of the time, embolism does not cause permanent complications. Our data highlight the importance of anticoagulation for patients acute atrial fibrillation in myocardial dysfunction and for patients with chronic atrial fibrillation in cases of mitral valvar heart disease to prevent peripheral embolism.
