Conservative management of pneumopericardium: A case of unexpected success.

A 79-year-old male with severe aortic stenosis was admitted with syncope and cranioencephalic traumatism with major nasal hemorrhage. While being prepared for surgical aortic valve replacement, a high-degree atrioventricular block was detected and a definite pacemaker was implanted.

Glycoprotein IIb/IIIa inhibitor use in cardiogenic shock complicating myocardial infarction: The Portuguese Registry of Acute Coronary Syndromes.

INTRODUCTION AND OBJECTIVES: Cardiogenic shock (CS) complicates 5-10% of cases of myocardial infarction (MI). Whether glycoprotein IIb/IIIa inhibitors (GPIs) are beneficial in these patients is controversial. Our aim is to assess the prognostic impact of GPI use on in-hospital mortality and outcomes in patients with MI and CS undergoing percutaneous coronary intervention (PCI). METHODS: Between October 2010 and December 2019, 27578 acute coronary syndrome (ACS) patients were included in the multicenter Portuguese Registry of Acute Coronary Syndromes. Of these, 357 with an MI complicated by CS were included in the analysis and grouped based on whether they received GPI therapy (with GPI, n=107 and without GPI, n=250). The primary endpoint was in-hospital mortality. Secondary endpoints included successful PCI and in-hospital reinfarction and major bleeding. RESULTS: Demographics and cardiovascular risk factors did not differ between groups. ST-elevation MI patients were more likely to receive GPIs (95% vs. 83%, p=0.002). In-hospital mortality was similar between groups (OR 1.80, 95% CI 0.96-3.37). Only age and the use of inotropes or intra-aortic balloon pump were predictors of mortality. Also, no differences between groups were noted for successful PCI (OR 0.33, 95% CI 0.62-4.06), reinfarction (OR 0.77, 95% CI 0.15-3.90), or major bleeding (OR 1.68, 95% CI 0.75-3.74). CONCLUSION: The use of GPIs in the context of MI with CS did not significantly impact in-hospital outcomes.

Chronic kidney disease in acute coronary syndromes: real-world data of long-term outcomes.

Aim: Patients with chronic kidney disease (CKD) are at increased cardiovascular risk. Methods: Patients with acute coronary syndrome were retrospectively allocated to three groups (stage 3A, stage 3B or stage 4) based on the Kidney Disease Improving Global Outcomes classification formulas: the CKD Epidemiology Collaboration (CKD-EPI; N = 401) and the modification of diet in renal disease (n = 355). The primary end point was all-cause mortality (median follow-up time, 32 months [15-70]). Results: Study results showed decreased median survival was associated with poor renal function for both the CKD-EPI (78 vs 61 vs 40 months, p = 0.014) and modification of diet in renal disease groups (68 vs 57 vs 32 months, p = 0.006). After adjustment, age (OR: 1.07; 95% CI: 1.01-1.14) and pulmonary artery systolic pressure (OR: 1.08; 95% CI: 1.03-1.14), but not estimated glomerular filtration rate, were associated with decreased survival. Conclusion: Study results suggest that poor outcomes after an acute coronary syndrome were associated with comorbidities rather than estimated glomerular filtration rate level.

Lay abstract Patients with chronic kidney failure have an elevated risk of heart attack or death. We studied patients with kidney failure and concurrent heart attack for 32 months (median). Our results suggest that poorer renal function was associated with an increased risk of death. However, the most important factors associated with survival were patient age and pulmonary artery systolic pressure and not the particular kidney function. Therefore, in this group of patients, comorbidities appear to play a role as survival determinants.
