Introduction: Hypertrophic cardiomyopathy (HCM), a prevalent genetic cardiac condition characterized by myocardial thickening, poses unique challenges in trauma care. Sparse evidence seems to agree that HCM patients have worse outcomes following non-cardiac surgeries, particularly emergent procedures. However, despite a prevalence of 1 in 500 in the US population, the intersection of HCM and Advanced Trauma Life Support (ATLS) remains undiscussed in current literature.

Case presentation: A 54-year-old female with unknown past medical history presented as a level 2 trauma alert following a motor vehicle collision. Due to persistent hypotension and transient bradycardia in the trauma bay a further cardiologic evaluation was performed and found severe hypertrophic obstructive cardiomyopathy (HOCM).

Clinical discussion: We report a case of a polytrauma patient found to have severe HOCM as well as provide a review of the literature including pathophysiological considerations in the management of the trauma patient with HCM.

Conclusions: Caring for the trauma patient with HCM requires a multidisciplinary strategy that integrates advanced cardiac imaging and cautious hemodynamic management, underlining the necessity for heightened awareness.

简介：肥厚型心肌病（HCM）是一种常见的遗传性心脏疾病，其特点是心肌增厚。这种疾病在创伤护理中带来了独特的挑战。现有证据似乎一致认为，肥厚型心肌病患者在接受非心脏手术后预后较差，尤其是紧急手术的情况下。然而，在美国人口中的患病率为1/500，目前的文献并未讨论HCM与高级创伤生命支持（ATLS）之间的交集。

病例介绍：一名54岁女性患者因车祸被列为二级创伤警报。由于在创伤急诊室中持续低血压和短暂心动过缓，进行了进一步的心脏检查，并发现患有严重的肥厚型梗阻性心肌病（HOCM）。

临床讨论：我们报道了一例复合伤患者被诊断为严重HOCM的病例，并回顾了相关文献，包括在创伤患者中管理HCM时的病理生理学考虑因素。

结论：对患有肥厚型心肌病（HCM）的创伤患者的护理需要一个多学科策略，该策略结合先进的心脏成像和谨慎的心血管状态管理，并强调提高对此类情况的认识的重要性。
