  • Title: Prior blunt chest trauma may be a cause of single vessel coronary disease; hypothesis and review.
    Author: Christensen MD, Nielsen PE, Sleight P.
    Journal: Int J Cardiol; 2006 Mar 22; 108(1):1-5. PubMed ID: 15964088.
    Abstract:
    Prompted by a case where a patient (with no risk factors, and single vessel disease) developed angina pectoris after previous blunt chest trauma, we searched Medline for blunt chest trauma and myocardial ischaemia. We found 77 cases describing AMI after blunt chest trauma, but only one reporting angina pectoris. We focused on the age and sex distribution, type of trauma, the angiography findings and the time interval between the trauma and the angiography. The age distribution was atypical, compared to AMI in general; 82% of the patients with AMI after blunt chest trauma were less than 45 years old, and only 2.5% more than 60 years old. The most common trauma was a road traffic accident, and the LAD was the vessel most often affected. Angiography revealed 12 cases with completely normal vessels, which might be due to spasm or recanalisation; 31 cases showed occlusion but no atherosclerosis, which strongly suggested a causal relation between the trauma and subsequent occlusion. AMI should therefore be considered in patients suffering from chest pain after blunt chest trauma. Because traumatic AMI might often be the result of an intimal tear or dissection, thrombolytic therapy might worsen the situation and acute PCI must be considered preferable. It seems likely that lesser damage could lead to longer-term stenosis we suspect that this sequence is grossly under-reported. This could have medico-legal implications.
