Spontaneous coronary artery dissection: a rare cause of acute coronary syndrome

We present a case of a 71-year-old man, with a history of hypertension and dyslipidaemia, who presented with typical cardiac chest pain and palpitations of 2 h duration. The examination revealed irregular pulse of 138 bpm, blood pressure 115/75 mm Hg, variable first and normal second heart sounds. The lungs were clear to auscultation. The ECG showed atrial fibrillation with a rapid ventricular rate. His heart rate was controlled with β blockers and the acute coronary syndrome treatment protocol was initiated. His baseline blood reports were within normal limits and two serial troponin I tests were negative. Coronary angiogram showed dissection in the left coronary system extending into the branch vessels and 30–40% stenosis in the right coronary artery. The patient underwent coronary artery bypass graft as an emergent case. He suffered a mild stroke postsurgery with complete functional recovery. He is being followed up in the clinic and has performed well.
