Case report of severe coronary artery disease complicated by malignant arrhythmia due to inherited thrombophilia

The principal clinical manifestation of thrombophilia is venous thromboembolism, which is also markedly linked to arterial thrombosis, including myocardial infarction. Nevertheless, patients presenting with an early-onset myocardial infarction are seldom screened for thrombophilic genes, resulting in delayed diagnosis and an unfavourable prognosis. This report presents the case of a young man who suffered an acute myocardial infarction as a result of thrombophilia. The patient had a history of deep vein thrombosis and was genetically tested to carry two thrombophilia susceptibility alleles at the PAI-1 (4G/5G) and MTHFR (C > T) loci. This ultimately resulted in severe coronary artery occlusion, myocardial scarring and frequent episodes of ventricular tachycardia, which had a significant impact on the patient's quality of life. The objective of this report was to enhance clinicians' awareness of embolism susceptibility. It is recommended that young and middle-aged patients with severe coronary artery stenosis undergo screening for embolism.
