Boussignac continuous positive airway pressure for the management of acute cardiogenic pulmonary edema: prospective study with a retrospective control group
<p>Abstract</p> <p>Background</p> <p>Continuous positive airway pressure (CPAP) treatment for acute cardiogenic pulmonary edema can have important benefits in acute cardiac care. However, coronary care units are usually not equipped and their personnel not adequately trained for applying CPAP with mechanical ventilators. Therefore we investigated in the coronary care unit setting the feasibility and outcome of the simple Boussignac mask-CPAP (BCPAP) system that does not need a mechanical ventilator.</p> <p>Methods</p> <p>BCPAP was introduced in a coronary care unit where staff had no CPAP experience. All consecutive patients transported to our hospital with acute cardiogenic pulmonary edema, a respiratory rate > 25 breaths/min and a peripheral arterial oxygen saturation of < 95% while receiving oxygen, were included in a prospective BCPAP group that was compared with a historical control group that received conventional treatment with oxygen alone.</p> <p>Results</p> <p>During the 2-year prospective BCPAP study period 108 patients were admitted with acute cardiogenic pulmonary edema. Eighty-four of these patients (78%) were treated at the coronary care unit of which 66 (61%) were treated with BCPAP. During the control period 66 patients were admitted over a 1-year period of whom 31 (47%) needed respiratory support in the intensive care unit. BCPAP treatment was associated with a reduced hospital length of stay and fewer transfers to the intensive care unit for intubation and mechanical ventilation. Overall estimated savings of approximately € 3,800 per patient were achieved with the BCPAP strategy compared to conventional treatment.</p> <p>Conclusion</p> <p>At the coronary care unit, BCPAP was feasible, medically effective, and cost-effective in the treatment of acute cardiogenic pulmonary edema. Endpoints included mortality, coronary care unit and hospital length of stay, need of ventilatory support, and cost (savings).</p
Quick identification of acute chest pain patients study (QICS)
<p>Abstract</p> <p>Background</p> <p>Patients with acute chest pain are often referred to the emergency ward and extensively investigated. Investigations are costly and could induce unnecessary complications, especially with invasive diagnostics. Nevertheless, chest pain patients have high mortalities. Fast identification of high-risk patients is crucial. Therefore several strategies have been developed including specific symptoms, signs, laboratory measurements, and imaging.</p> <p>Methods/Design</p> <p>The Quick Identification of acute Chest pain Study (QICS) will investigate whether a combined use of specific symptoms and signs, electrocardiography, routine and new laboratory measures, adjunctive imaging including electron beam (EBT) computed tomography (CT) and contrast multislice CT (MSCT) will have a high diagnostic yield for patients with acute chest pain. All patients will be investigated according a standardized protocol in the Emergency Department. Serum and plasma will be frozen for future analysis for a wide range of biomarkers at a later time point. The primary endpoint is the safe recognition of low-risk chest pain patients directly at presentation. Secondary endpoint is the identification of a wide range of sensitive predictive clinical markers, chemical biomarkers and radiological markers in acute chest pain patients. Chemical biomarkers will be compared to quantitative CT measurements of coronary atherosclerosis as a surrogate endpoint. Chemical biomarkers will also be compared in head to head comparison and for their additional value.</p> <p>Discussion</p> <p>This will be a very extensive investigation of a wide range of risk predictors in acute chest pain patients. New reliable fast and cheap diagnostic algorithm resulting from the test results might improve chest pain patients' prognosis, and reduce unnecessary costs and diagnostic complications.</p
Impact of electrical neuro stimulation on persistent ST elevation after successful reperfusion by primary percutaneous coronary intervention
Aims: To study the effect of electrical neurostimulation on the ST segment shift in patients with ST elevation myocardial infarction (STEMI) with residual ST elevation after primary percutaneous coronary intervention (PCI). Methods: After primary PCI, 38 patients with STEMI were divided into 2 groups. Group I received 15 minutes of active neurostimulation after the baseline electrocardiogram (ECG); group 2 received 15 minutes of active neurostimulation after 15 minutes of nonactive neurostimulation. Results: In group 1, ST elevation decreased with neurostimulation from 0.65 +/- 0.56 to 0.55 +/- 0.51 (P = .02) and to 0.50 +/- 0.52 (P = .01) without electrical neurostimulation. In group 2, ST elevation changed without neurostimulation from 0.37 +/- 0.32 to 0.33 +/- 0.30 (P = NS) and to 0.28 +/- 0.27 (P = .0 1) with electrical neurostimulation. In a posthoc analysis, 17 responders had higher ST elevation at the ECG before active electrical neurostimulation than 21 nonresponders (P = .001). Conclusion: Electrical neurostimulation may result in significant additional reduction of ST elevation in STEMI after reperfusion treatment, in particular in patients with marked ST elevation on the first ECG after successful primary PCI.

Long-term outcome of patients after out-of-hospital cardiac arrest in relation to treatment:a single-centre study
Introduction: Outcome after out-of-hospital cardiac arrest (OHCA) remains poor. With the introduction of automated external defibrillators, percutaneous coronary intervention (PCI) and mild therapeutic hypothermia (MTH) the prognosis of patients after OHCA appears to be improving. The aim of this study was to evaluate short and long-term outcome among a non-selected population of patients who experienced OHCA and were admitted to a hospital working within a ST elevation myocardial infarction network. Methods: All patients who achieved return of spontaneous circulation (ROSC) (n=456) admitted to one hospital after OHCA were included. Initial rhythm, reperfusion therapy with PCI, implementation of MTH and additional medical management were recorded. The primary outcome measure was survival (hospital and long term). Neurological status was measured as cerebral performance category. The inclusion period was January 2003 to August 2010. Follow-up was complete until April 2014. Results: The mean patient age was 63±14 years and 327 (72%) were men. The initial rhythm was ventricular fibrillation, pulseless electrical activity, asystole and pulseless ventricular tachycardia in 322 (71%), 58 (13%), 55 (12%) and 21 (5%) of the 456 patients, respectively. Treatment included PCI in 191 (42%) and MTH in 188 (41%). Overall in-hospital and long-term (5-year) survival was 53% (n=240) and 44% (n=202), respectively. In the 170 patients treated with primary PCI, in-hospital survival was 112/170 (66%). After hospital discharge these patients had a 5-year survival rate of 99% and cerebral performance category was good in 92%. Conclusions: In this integrated ST elevation myocardial infarction network survival and neurological outcome of selected patients with ROSC after OHCA and treated with PCI was good. There is insufficient evidence about the outcome of this approach, which has a significant impact on utilisation of resources. Good quality randomised controlled trials are needed. In selected patients successfully resuscitated after OHCA of presumed cardiac aetiology, we believe that a more liberal application of primary PCI may be considered in experienced acute cardiac referral centres
The value and limitations of a wound inspection clinic after cardiac device implantation
Background: Due to the growing number of cardiac device implantations it is important to develop methods to reduce device-implantation related complications. Aims: To determine whether a wound inspection clinic can play a role in the detection of device-implantation related complications. Methods: Single-center observational study evaluating patients who received a pacemaker or implantable cardioverter-defibrillator (ICD). Results: Of 159 patients who received an appointment for the wound inspection clinic, 52 (33%) received a pacemaker and 107 (67%) received an ICD. The majority had no signs of infection. Pain (n=13, 8%) and swelling (n=11, 7%) were the most frequent signs observed, but they never necessitated intervention and recovered spontaneously in all patients. During follow-up (mean 20 9 weeks), complications occurred in 10 patients (6%). Most complications occurred early, within 4 days after implantation. The two late complications (at 19 and 41 days) could not be recognized at the wound inspection clinic. Conclusion: We found no useful role for a wound inspection clinic two weeks post-implant to detect device-related complications. Open rapid access to the pacemaker/ICD center for patients with signs and symptoms of (threatening) complications seems to be more appropriate to manage post-implant patients.

The Value and Limitations of a Wound Inspection Clinic After Cardiac Device Implantation
A 64-year old man who sustained many episodes of acute cardiogenic pulmonary edema successfully treated with Boussignac continuous positive airway pressure:A case report
Continuous positive airway pressure (CPAP) is standard treatment for patients with acute cardiogenic pulmonary edema. We describe a patient who had 21 episodes of acute cardiogenic pulmonary edema due to very poor patient compliance. This 64-year old man had end-stage congestive heart failure based on systolic left ventricular dysfunction following two myocardial infarctions. In addition to routine medical treatment 15 episodes of pulmonary edema were successfully treated with Boussignac continuous positive airway pressure (BCPAP). The BCPAP system is a simple, disposable, FDA-approved device that delivers positive pressure without a ventilator. This extraordinary case underscores the utility of the BCPAP system to avoid repeated intubation and mechanical ventilation in patients with cardiogenic pulmonary edema.
