IntroductionST elevation myocardial infarction (STEMI) is a high acuity diagnosis that requires prompt recognition and developed system responses to reduce morbidity and mortality. There is a paucity of literature describing active duty (AD) military personnel with STEMI syndromes at military treatment facilities (MTFs). This study aims to describe AD military members with STEMI diagnoses, military treatment facility management, and subsequent military dispositions observed.Materials And MethodsWe performed a single-center, retrospective review of all STEMI diagnoses at San Antonio Military Medical Center (SAMMC) from January 2008 to June 2018. Patients met inclusion in the analysis if they were (1) AD personnel in the United States Air Force (USAF) or United States Army (USA) and (2) presented with electrocardiogram findings and cardiac biomarkers diagnostic of a STEMI diagnosis. ASCVD and STEMI diagnoses were confirmed by board certified interventional cardiologists with coronary angiography. The 2017 American College of Cardiology (ACC) STEMI clinical performance and quality measures were used as the standard of care metrics for our case reviews.ResultsA total of 236 patients were treated for STEMI at SAMMC during the study period. Eight (3.4%) of these cases met inclusion criteria of being AD status at the time of diagnosis. Five (63%) of the AD STEMI diagnoses were USA members, three (37%) were USAF members, 50% were Caucasian, and 100% were male sex. The average age and body mass index were 46.3 ± 5.5 years old and 28.5 ± 3.1 kg/m 2, respectively. Preexisting cardiovascular risk factors were present in six (75%) of the individuals with hypertension being most common (63%). The eight patients had a baseline average low-density lipoprotein cholesterol of 110 ± 39 mg/dL, total cholesterol of 180 ± 49 mg/dL and calculated 10-year risk of atherosclerotic cardiovascular disease (ASCVD) 3.9 ± 1.6%. 100% of patients underwent primary percutaneous coronary intervention (PCI) within 90 minutes of presentation (average door-to-balloon time 59.3 ± 24 min). Single-vessel disease was found in all eight patients and seven of them underwent drug-eluting stent placement (average number of stents 2 ± 1.5). Performance and quality measures were met in all applicable categories including door-to-balloon times, discharge medical therapies, and cardiac rehabilitation enrollments for 100% AD personnel. Reported adverse events included two stent thromboses and two vascular complications. Three of eight individuals (37.5%) were diagnosed with behavioral health disorders secondary to their acute coronary syndrome. Medical retirement secondary to STEMI diagnosis occurred in 87.5% of subjects and all study personnel medically retired within 24 months (average 12.8 ± 7.9 months).ConclusionsAD personnel represent a small minority of MTF STEMI diagnoses and present with lower risk cardiovascular profiles. AD personnel received standard STEMI management compared to national performance measures, and were deployment ineligible after STEMI diagnoses. Further studies are needed to definitively explore the appropriate military dispositions for members with STEMI diagnoses and acute coronary syndromes.© The Author(s) 2020.
