Review of the Association Between Long-Term and Current Systemic Steroid Use With Electromechanical Complications and Inpatient Mortality After ST-Elevation Myocardial Infarction.

Background The impact of long-term systemic steroid use on electrical and mechanical complications following ST-segment elevation myocardial infarction (STEMI) has not been extensively studied. Methods In a retrospective cohort study of the National Inpatient Sample (NIS) from 2018 to 2020, adults admitted with STEMI were dichotomized based on the presence of long-term (current) systemic steroid (LTCSS) use. The primary outcome was all-cause mortality. Secondary outcomes included a composite of mechanical complications, electrical, hemodynamic, and thrombotic complications, as well as revascularization complexity, length of stay (LOS), and total charge. Multivariate linear and logistic regressions were used to adjust for confounders. Results Out of 608,210 admissions for STEMI, 5,310 (0.9%) had LTCSS use. There was no significant difference in the odds of all-cause mortality (aOR: 0.89, 95%CI: 0.74-1.08, p-value: 0.245) and the composite of mechanical complications (aOR: 0.74, 95%CI: 0.25-2.30, p-value: 0.599). LTCSS use was associated with lower odds of ventricular tachycardia, atrioventricular blocks, new permanent-pacemaker insertion, cardiogenic shock, the need for mechanical circulatory support, mechanical ventilation, cardioversion, a reduced LOS by 1 day, and a reduced total charge by 34,512 USD (all p-values: <0.05). There were no significant differences in the revascularization strategy (coronary artery bypass graft (CABG) vs. percutaneous coronary interventions (PCI)) or in the incidence of composite thrombotic events. Conclusion LTCSS use among patients admitted with STEMI was associated with lower odds of electrical dysfunction and hemodynamic instability but no difference in the odds of mechanical complications, CABG rate, all-cause mortality, cardiac arrest, or thrombotic complications. Further prospective studies are needed to evaluate these findings further.

Massive Left Ventricular Thrombus Causing Bilateral Posterior Cerebral Artery Stroke: A Case Report and Review of Literature.

Left ventricular thrombus (LVT) is a major complication of acute myocardial infarction (MI). Here, we describe the case of a 36-year-old female with a history of acute anterior MI six years prior to hospitalization, who presented with bilateral vision loss due to a bilateral embolic posterior cerebral artery (PCA) stroke in the setting of a 5.7 x 1.7 cm LVT. She underwent bilateral PCA thrombectomy, which led to improvement of her symptoms. Her LVT was managed non-surgically with apixaban and clopidogrel. Her case highlights the need for more medical education about LVT, as quick initiation of anticoagulation is essential in improving outcomes. We review the existing literature to explain the pathogenesis, diagnosis, and treatment of LVT.

Delayed Presentation During COVID-19 Pandemic Leading to Post-Myocardial Infarction Ventricular Septal Defect.

Post-myocardial infarction ventricular septal defect (post-MI VSD) is a rare complication of ST-elevation myocardial infarction (STEMI) with an incidence of <1% in early revascularization era. Here we present the case of a 66-year-old woman with post-MI VSD owing to delay in her presentation in the current pandemic. Patient presented with worsening back pain and chest pain with confusion, and an EKG positive for inferior wall STEMI. She underwent emergent percutaneous intervention with placement of drug-eluting stent in her right coronary artery. She developed worsening heart failure and new-onset heart murmur and was found to have a VSD on a transthoracic echo. Because of her poor prognosis, family decided to pursue comfort care and patient unfortunately passed. Delay in seeking health care during the pandemic, as seen in our patient, is multifactorial including fear of contracting infection, decreased emergency medical services members, and concerns for overburdening healthcare systems. Lack of standardized in-hospital approach to emergencies while ensuring adequate protection from infection to healthcare workers, especially during the initial phase of the pandemic, led to increased door-to-balloon times in addition to the increased time to first medical contact. The importance of media outreach ensuring availability of health care in emergencies, changing emergency response algorithms to ensure safety of patients and healthcare providers, and including thrombolytic therapy where there is a delay due to stringent screening or delayed COVID-19 testing can be used to prevent worsening complications following STEMI.
