Acute Myocardial Infarction With Cardiogenic Shock Due to Pericardial Constriction and Multivessel Coronary Obstruction.

We present a rare case of cardiogenic shock and multivessel coronary compression due to focal pericardial inflammation and constriction. The patient was treated in the acute phase with coronary stenting and temporary mechanical support. Multimodality imaging was essential in elucidating the diagnosis.

Factors Associated With Ineligibility for PCI Differ Between Inpatient and Outpatient ST-Elevation Myocardial Infarction.

OBJECTIVES: Without early revascularization, both inpatient and outpatient STEMIs have poor outcomes. Reasons for denying PCI for STEMI, however, remain uncertain. This single-center retrospective cohort study compares factors and outcomes associated with ineligibility for PCI between inpatients and outpatients following ST-elevation myocardial infarction (STEMI). METHODS: A total of 1,759 STEMI patients between June 2009 and January 2015 were assessed. Individual medical records were reviewed to obtain reasons for PCI ineligibility for STEMI patients who did not receive reperfusion therapy. RESULTS: Compared to outpatients with STEMI (n = 1,688), inpatients (n = 71) were less likely to receive coronary angiography (60.6% vs 95.9%; P < 0.001) or PCI (50.7% vs 80.9%; P < 0.001), with longer ECG/door to first device activation times (97 [78, 131] vs 63 [49, 78] minutes; P < 0.001). When coronary angiography was performed, however, similar rates of PCI and procedural success were seen in both groups. Principal contraindication for PCI was risk of bleeding within the inpatient population and complex coronary artery disease within the outpatient population. Total in-hospital mortality was higher in inpatient STEMIs compared to outpatients (42.2% vs 10.0%; P < 0.001), but lower for patients eligible for PCI in both groups. CONCLUSIONS: Reasons for PCI ineligibility differ between inpatient and outpatient STEMIs. Inpatients have increased risks of bleeding, lower coronary angiography and PCI use, and higher in-hospital mortality. Especially for inpatients, specific PCI STEMI protocols that anticipate and overcome types of ineligibility and delay for cardiac catheterization may improve outcomes.

The Effects of Job Instability and Financial Strain on C-Reactive Protein in a Sample of Mexican Immigrants.

OBJECTIVE: Mexican immigrants have lower cardiovascular disease risk than US citizens, but risk increases with level of acculturation. Our study investigated whether job stress and financial strain would be related to inflammation (C-reactive protein), lipids, and blood pressure, and if they would play a role in the acculturation process in Mexican immigrants. METHODS: A sample of 310 Mexican immigrants living in the United States were studied on measures of job stress, financial strain, acculturation, and cardiovascular disease risk factors (C-reactive protein, lipids, and blood pressure). RESULTS: Job instability, financial strain, and acculturation, were related to inflammation, but psychological demands and decision latitude were not related. Lipids and blood pressure were not related to the variables of interest. Body mass index (BMI) was related to both increased acculturation and inflammation, and when controlling for BMI, acculturation was no longer a significant predictor of inflammation. Job instability and financial strain remained significant predictors of inflammation after controlling for BMI, sex, and age. Job instability and financial strain were not related to acculturation, suggesting that these factors are significant stressors for both newly arrived and more established immigrants. CONCLUSIONS: Job instability and financial strain predict increased inflammation in Mexican immigrants but they do not play a role in the relationship between acculturation and C-reactive protein. The effects of acculturation on inflammation in this study were mediated by BMI.
