Recently, validated clinical decision rules have been developed that avoid unnecessary use of computed tomographic pulmonary angiography (CTPA) in patients with suspected pulmonary embolism (PE) in the emergency department (ED). To measure any resulting change in CTPA use for suspected PE. Retrospective analysis. 26 European EDs in 6 countries. Patients with CTPA performed for suspected PE in the ED during the first 7 days of each odd month between January 2015 and December 2019. The primary end points were the CTPAs done for suspected PE in the ED and the number of PEs diagnosed in the ED each year adjusted to an annual census of 100 000 ED visits. Temporal trends were estimated using generalized linear mixed regression models. 8970 CTPAs were included (median age, 63 years; 56% female). Statistically significant temporal trends for more frequent use of CTPA (836 per 100 000 ED visits in 2015 vs. 1112 in 2019; P < 0.001), more diagnosed PEs (138 per 100 000 in 2015 vs. 164 in 2019; P = 0.028), a higher proportion of low-risk PEs (annual percent change [APC], 13.8% [95% CI, 2.6% to 30.1%]) with more ambulatory management (APC, 19.3% [CI, 4.1% to 45.1%]), and a lower proportion of intensive care unit admissions (APC, -8.9% [CI, -17.1% to -0.3%]) were observed. Data were limited to 7 days every 2 months. Despite the recent validation of clinical decision rules to limit the use of CTPA, an increase in the CTPA rate along with more diagnosed PEs and especially low-risk PEs were instead observed. None specific for this study.

Background—: The value of prehospital initiation of glycoprotein IIb/IIIa inhibitors remains a controversial issue. We sought to investigate whether in-ambulance initiation of abciximab in patients with ST-segment elevation myocardial infarction (STEMI) improves ST-segment elevation resolution (STR) after primary percutaneous coronary intervention (PCI). Methods and Results—: MISTRAL (Myocardial Infarction with ST-elevation Treated by Primary Percutaneous Intervention Facilitated by Early Reopro Administration in Alsace) is a prospective, randomized, double-blind study. Two hundred and fifty-six patients with acute STEMI were allocated to receive abciximab either in the ambulance (ambulance group, n=127) or in the catheterization laboratory (hospital group, n=129). The primary end point was complete (>70%) STR after PCI. Complete STR was not significantly different between the 2 groups (before PCI, 21.6% versus 15.5%, P =0.28; after PCI, 70.3% versus 65.8%, P =0.49). Thrombolysis In Myocardial Infarction (TIMI) 2 to 3 flow rates before PCI tended to be higher in the ambulance group (46.8% versus 35%, P =0.08) but not after PCI (70.3% versus 65.8%, P =0.49). Slow flow tended to be lower (5.6% versus 13.4%, P =0.07), and distal embolization occurred significantly less often in the ambulance group (8.1% versus 21.1%, P =0.008). One- and 6-month major adverse cardiac event rates were low and similar in both groups. Conclusions—: Early ambulance administration of abciximab in STEMI did not improve either STR or TIMI flow rate after PCI. However, it tended to improve TIMI flow pre-PCI and decreased distal embolization during procedure. Larger studies are needed to confirm these results.

An appropriate diagnostic process is crucial for managing patients with acute heart failure (AHF) in emergency department (ED). Our study aims to describe the characteristics and therapeutic management of patients admitted to the ED for dyspnea suspected to have AHF, their in-hospital pathway of care and their in-hospital outcome. Consecutive patients admitted in 26 French ED for dyspnea suspected to be the consequence of AHF, prior to in hospital diagnostic test, were prospectively included at the time of their admission in the DeFSSICA Survey. Clinical characteristics at admission were recorded by the ED physicians. At discharge from ED, patients were categorized as AHF or non-AHF based on the final diagnosis reported in the discharge summary. The completeness of the data was controlled by the local investigator. From 16/6/2014 to 7/7/2014, 699 patients were included, of whom 537 (77 %) had a final diagnosis of AHF at discharge. Patients with AHF were older (median 83 vs 79 years, p = 0.0007), more likely to have hypertension (71 % vs 57 %, p = 0.002), chronic HF (54 % vs 37 %, p = 0.0004), atrial fibrillation (45 % vs 34 %, p = 0.02) and history of hospitalization for AHF in the previous year (40 % vs 18 %, p < 0.0001) when compared to patients without AHF. Furosemide and oxygen were used in approximately 2/3 of the patients in the ED (respectively 75 and 68 %) whereas nitrates were in 19 % of the patients. Diagnostic methods used to confirm AHF included biochemistry (100 %), pro-B-type natriuretic peptide (90 %), electrocardiography (98 %), chest X-ray (94 %), and echography (15 %) which only 18 % of lung ultrasound. After the ED visit, 13 % of AHF patients were transferred to the intensive care unit, 28 % in cardiology units and 12 % in geriatric units. In-hospital mortality was lower in AHF vs non-AHF patients (5.6 % vs 14 %, p = 0.003). DeFSSICA, a large French observational survey of acute HF, provides information on HF presentation and the French pathway of care. Patients in DeFSSICA were elderly, with a median age of 83 years. Compared with the French OFICA study, patients in DeFSSICA were more likely to have hypertension (71 % vs 62 %) and atrial fibrillation (45 % vs 38 %). As atrial fibrillation and a rapid heart rate have been closely linked to mortality, detection of atrial fibrillation should be considered systematically.The limited use of nitrates in DeFSSICA may be related to the median SBP of 140 (121–160) mmHg. However, our use of nitrates was similar to those in the EAHFE (20.7 %) and OPTIMIZE-HF (14.3 %) registries. In line with guidelines, the proportions of patients who underwent ECG, biological analysis, or chest X-ray were all >90 % in DeFSSICA. Similarly, BNP or pro-BNP was measured in 93 % of patients, compared with 82 % of patients in the OFICA study. Although BNP may be helpful when the diagnosis of HF is in doubt, ultrasound remains the gold standard. The use of ultrasound in the ED has been reported to accelerate the diagnosis of HF and the initiation of treatment, and shorten the length of stay. In-hospital mortality of HF patients in DeFSSICA was 6.4 %, slightly lower than in the OFICA study (8.2 %). Improved interdisciplinary cooperation has been highlighted as a key factor for the improvement of HF patient care. DeFSSICA shows that patients admitted for dyspnea suspected to be the consequence of AHF are mostly elderly. The diagnosis of AHF is difficult to ascertain based on clinical presentation in patients with dyspnea. Novel diagnostic techniques such as thoracic ultrasound are warranted to provide the right treatment to the right patients in the ED as early as possible.
