Elevación transitoria del ST, angina variante de Prinzmetal / Transitory ST elevation, Prinzmetal angina

La angina variante de Prinzmetal es una enfermedad poco frecuente en Colombia, pero con alto riesgo de complicaciones sino se diagnostica e inicia su manejo precozmente. Así mismo, es una de las causas de elevación del segmento ST en el electrocardiograma en pacientes con dolor torácico. Se expone el caso de una paciente con enfermedad vasoespástica y cuya presentación clínica simuló una infarto agudo de miocardio y luego de realizar los estudios diagnósticos se pudo descartar éste y dar el tratamiento adecuado.

Prinzmetal variant angina is an uncommon disease in Colombia, it have high risk of complications if is not diagnosed early and a rapid treatment starter. Also, it is one of the causes of ST segment elevation on the electrocardiogram in patients with chest pain in the emergency department. We describe the case of a patient with vasospastic disease whose clinical presentation simulates a heart attack and after diagnostic studies that allowed dismiss this and, the proper treatment was given.

Ventricular Tachycardia Associated Syncope in a Patient of Variant Angina without Chest Pain

A 68-year-old man was admitted for a syncope workup. After routine evaluation, he was diagnosed with syncope of an unknown cause and was discharged from the hospital. He was readmitted due to dizziness. On repeated Holter monitoring, polymorphic ventricular tachycardia was detected during syncope. We performed intracoronary ergonovine provocation test; severe coronary spasm was induced at 70% stenosis of the proximal left anterior descending artery. The patient was treated with percutaneous coronary intervention. We present a rare case of syncope induced by ventricular arrhythmia in a patient with variant angina without chest pain.

Recurrent myocardial infarction secondary to Prinzmetal's variant angina

Prinzmetal's variant angina describes chest pain secondary to reversible coronary artery vasospasm in the context of both diseased and non-diseased coronary arteries. Symptoms typically occur when the patient is at rest and are associated with transient ST-segment elevation. Acute episodes respond to glyceryl trinitrate, but myocardial infarction and other potentially fatal complications can occur, and long-term management can be challenging. Although it is not well understood, the underlying mechanism appears to involve a combination of endothelial damage and vasoactive mediators. In this case, a 35-year-old woman with myocardial infarction secondary to coronary artery vasospasm experienced recurrent chest pain. Coronary angiography revealed severe focal stenosis in the mid left anterior descending artery, which completely resolved after administration of intracoronary glyceryl trinitrate. The patient was discharged on nitrates and calcium channel blockers. The patient re-presented with another myocardial infarction, requiring up-titration of medical therapy.
