RESUMO

BACKGROUND: Acute pericardial pathologies, such as pericardial effusion, pericarditis, and cardiac tamponade, have been reported rarely in patients presenting as ST-elevation myocardial infarction (STEMI). We present a series of 3 patients with STEMI, where an undiagnosed pericardial effusion led to pericardial tamponade and subsequent cardiocirculatory collapse. CASE REPORTS: This is a case series of 3 patients, all women, aged 72, 64, and 54 years who presented to the emergency department with chest pain or syncope and were found to have STEMI with hemodynamic instability. They were taken to the catheterization laboratory for urgent coronary revascularization requiring mechanical circulatory support (intra-aortic balloon pump or impella). During catheterization, all 3 patients were diagnosed with large pericardial effusion using hemodynamic parameters and bedside transesophageal echocardiogram. Commonly ignored, pericardial tamponade and acute large pericardial effusion can be the cause of cardiocirculatory collapse. Two of the 3 patients survived with aggressive interventions requiring pericardial drains, long-term mechanical circulatory support, and effective postoperative rehabilitation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: It is important for treating clinicians, including emergency physicians, intensivist, and cardiologist, to consider the differential of a cardiac tamponade due to a pericardial effusion as a potential cause for hypotension in patients with an acute STEMI.

RESUMO

Percutaneous ventricular assist devices (pVADs) are indicated to provide hemodynamic support in high-risk percutaneous interventions and cardiogenic shock. However, there is a paucity of published data regarding the etiologies and predictors of 90-day readmissions following pVAD use. We studied the data from the US Nationwide Readmissions Database (NRD) for the years 2013 and 2014. Patients with a primary discharge diagnosis of pVAD use were collected by searching the database for International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedural code 37.68 (Impella and TandemHeart devices). Amongst this group, we examined 90-day readmission rates. Comorbidities as identified by "CM_" variables provided by the NRD were also extracted. The Charlson Comorbidity Index was calculated using appropriate ICD-9-CM codes, as a secondary diagnosis. A 2-level hierarchical logistic regression model was then used to identify predictors of 90-day readmission following pVAD use. Records from 7074 patients requiring pVAD support during hospitalization showed that 1562 (22%) patients were readmitted within 90 days. Acute decompensated heart failure (22.6%) and acute coronary syndromes (11.2%) were the most common etiologies and heart failure (odds ratio [OR]: 1.39, 95% confidence interval [CI]: 1.17-1.67), chronic obstructive pulmonary disease (OR: 1.26, 95% CI: 1.07-1.49), peripheral vascular disease (OR: 1.305, 95% CI: 1.09-1.56), and discharge into short- or long-term facility (OR: 1.28, 95% CI: 1.08-1.51) were independently associated with an increased risk of 90-day readmission following pVAD use. This study identifies important etiologies and predictors of short-term readmission in this high-risk patient group that can be used for risk stratification, optimizing discharge, and healthcare transition decisions.
