ABSTRACT

A Angina de Prinzmetal foi descrita em 1959, sendo caracterizada por ataques recorrentes de dor precordial ao repouso associados à elevação transitória do segmento S-T. Documentamos o caso de um homem, 58 anos, tabagista, previamente livre de sintomas coronarianos, que foi admitido com dor retroesternal aguda. O eletrocardiograma mostrou elevação transitória do segmento S-T nas derivações V1 a V3, que retornou à linha de base após cessar a dor. O nível sérico das enzimas cardíacas estava normal. O ecocardiograma não apresentou alterações segmentares da contratilidade do ventrículo esquerdo e a coronariografia demonstrou obstrução severa no terço proximal da artéria descendente anterior e na artéria diagonal. Foi tratado com nitrato, diltiazem e angioplastia com stent e não apresentou novos sintomas. Foi confirmado o diagnóstico de espasmo coronariano. Cabe ressaltar a importância de se incluir a Angina de Prinzmetal no diagnóstico diferencial da Síndrome Coronariana Aguda para que novos casos sejam precocemente diagnosticados.


Prinzmetal's Angina was described in 1959. It is characterized by recurrent episodes of spontaneous chest pain associated with transient ST-segment elevation. We report herein a case of a 58 year-old previously healthy man, who was admitted with acute retrosternal pain. Smoking was the only risk factor for atherosclerotic disease. The electrocardiogram showed transient ST-segment elevations from V1 toV3 leads. The cardiac enzymes tested normal. The echocardiogram didn't exhibit any abnormality in the left ventricular contractility and the coronary angiography revealed severe occlusion in both proximal part of the left anterior descending artery and the diagonal artery. The patient received nitrate and diltiazen, and the coronary lesions were treated with balloon angioplasty plus stenting. The follow up was uneventful. The diagnosis of variant angina (Prinzmental's angina) was made. In conclusion, Prinzmetal's Angina should always be included in the differential diagnosis of Acute Coronary Syndrome, so that new cases can be early diagnosed and treated.

ABSTRACT

Mulher com 61 anos de idade, portadora há 11 anos de prótese mecânica, foi internada com dispnéia súbita, palidez e fibrilação atrial. A avaliação diagnóstica incluiu ecocardiografia transesofágica, que demonstrou restrição importante da mobilidade de um dos folhetos da prótese mitral e imobilidade do outro, juntamente com imagem de espessamento compatível com trombo aderido à valva. Foi feito o diagnóstico de trombose de prótese mecânica mitral e instituída terapia trombolítica (rtPA) com sucesso. A paciente está em acompanhamento há mais de um ano, com evolução satisfatória.


A 61-year-old female patient using a mechanical prosthesis for 11 years was admitted to the hospital with sudden dyspnea, pallor and atrial fibrillation. The diagnostic evaluation included transesophageal echocardiogram, which showed a significantly reduced motion of one of the leaflets of the mitral prosthesis and immobility of the other, in addition to a thickened structure compatible with a thrombus adherent to the valve. The patient was diagnosed with thrombosis of mechanical mitral valve prosthesis. Thrombolytic therapy (rtPA) was started successfully. The patient has been followed up for more than one year with a favorable outcome.
