- 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.

- BACKGROUND: 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. METHODS: 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. RESULTS: 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 euro 3,800 per patient were achieved with the BCPAP strategy compared to conventional treatment. CONCLUSION: 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).

- OBJECTIVE: Boussignac continuous positive airway pressure (BCPAP) delivered by face mask is useful for patients with acute cardiogenic pulmonary edema (ACPE). Although BCPAP is medically effective, we observed that not all suitable patients received it. In this descriptive, prospective, cohort study, we explored the experiences and attitudes of both patients and staff with BCPAP. METHODS: Patients were interviewed 12 to 48 hours after treatment with BCPAP. Nurses on the coronary care unit were interviewed on their knowledge, skills, experiences, and opinions concerning BCPAP. RESULTS: Of 117 patients with ACPE, 87 patients (74%) received BCPAP treatment. It was decided not to administer BCPAP in 30 patients with ACPE (26%). Patients who received BCPAP found that the reduction of dyspnea outweighed any discomfort. Barriers for the use of BCPAP were not related to nurses' skills but to the following: the nurses' belief that BCPAP created major discomfort, the lack of guidelines, the ultimate improvement of oxygenation without BCPAP, and the more labor-intensive treatment. CONCLUSION: Overestimation of patient discomfort by nurses and system-related factors impeded the use of BCPAP for all patients with ACPE.

- BACKGROUND—: Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration during PCI in patients with STEMI. METHODS—: Included were large (N≥1000) randomized controlled trials comparing manual thrombectomy vs. PCI alone in patients with STEMI. Individual patient data was provided by the leadership of each trial. The pre-specified primary efficacy outcome was cardiovascular (CV) mortality within 30 days and the primary safety outcome was stroke or transient ischemic attack (TIA) within 30 days. RESULTS—: The 3 eligible randomized trials (TAPAS, TASTE and TOTAL) enrolled 19,047 patients, of whom 18,306 underwent PCI and were included in the primary analysis. CV death at 30 days occurred in 221 (2.4%) of 9155 patients randomized to thrombus aspiration and 262 (2.9%) of 9151 randomized to PCI alone (hazard ratio (HR) 0.84; 95% CI 0.70-1.01, p=0.06). Stroke or TIA occurred in 66 (0.8%) randomized to thrombus aspiration and 46 (0.5%) randomized to PCI alone (odds ratio [OR] 1.43 95% CI 0.98-2.1, p=0.06). There were no significant differences in recurrent myocardial infarction, stent thrombosis, heart failure or target vessel revascularization. In the subgroup with high thrombus burden (TIMI thrombus grade ≥3) thrombus aspiration was associated with less CV death (170 [2.5%] vs. 205 [3.1%] HR 0.80; 95% CI 0.65-0.98, p =0.03), and with more stroke or TIA (55 [0.9%] vs. 34 [0.5%] OR 1.56; 95% CI 1.02-2.42, p=0.04). However, the interaction p-values were 0.32 and 0.34, respectively. CONCLUSIONS—: Routine thrombus aspiration during STEMI PCI did not improve clinical outcomes. In the high thrombus burden subgroup the trends toward reduced CV death and increased stroke or TIA provide a rationale for future trials of improved thrombus aspiration technologies in this high-risk subgroup.

- BACKGROUND: Thrombus aspiration during percutaneous coronary intervention (PCI) for the treatment of ST-segment-elevation myocardial infarction (STEMI) has been widely used; however, recent trials have questioned its value and safety. In this meta-analysis, we, the trial investigators, aimed to pool the individual patient data from these trials to determine the benefits and risks of thrombus aspiration during PCI in patients with ST-segment-elevation myocardial infarction. METHODS: Included were large (n >= 1000), randomized, controlled trials comparing manual thrombectomy and PCI alone in patients with ST-segment-elevation myocardial infarction. Individual patient data were provided by the leadership of each trial. The prespecified primary efficacy outcome was cardiovascular mortality within 30 days, and the primary safety outcome was stroke or transient ischemic attack within 30 days. RESULTS: The 3 eligible randomized trials (TAPAS [Thrombus Aspiration During Percutaneous Coronary Intervention in Acute Myocardial Infarction], TASTE [Thrombus Aspiration in ST-Elevation Myocardial Infarction in Scandinavia], and TOTAL [Trial of Routine Aspiration Thrombectomy With PCI Versus PCI Alone in Patients With STEMI]) enrolled 19 047 patients, of whom 18 306 underwent PCI and were included in the primary analysis. Cardiovascular death at 30 days occurred in 221 of 9155 patients (2.4%) randomized to thrombus aspiration and 262 of 9151 (2.9%) randomized to PCI alone (hazard ratio, 0.84; 95% confidence interval, 0.70-1.01; P=0.06). Stroke or transient ischemic attack occurred in 66 (0.8%) randomized to thrombus aspiration and 46 (0.5%) randomized to PCI alone (odds ratio, 1.43; 95% confidence interval, 0.98-2.10; P=0.06). There were no significant differences in recurrent myocardial infarction, stent thrombosis, heart failure, or target vessel revascularization. In the subgroup with high thrombus burden (TIMI [Thrombolysis in Myocardial Infarction] thrombus grade >= 3), thrombus aspiration was associated with fewer cardiovascular deaths (170 [2.5%] versus 205 [3.1%]; hazard ratio, 0.80; 95% confidence interval, 0.65-0.98; P=0.03) and with more strokes or transient ischemic attacks (55 [0.9%] versus 34 [0.5%]; odds ratio, 1.56; 95% confidence interval, 1.02-2.42, P=0.04). However, the interaction P values were 0.32 and 0.34, respectively. CONCLUSIONS: Routine thrombus aspiration during PCI for ST-segment-elevation myocardial infarction did not improve clinical outcomes. In the high thrombus burden group, the trends toward reduced cardiovascular death and increased stroke or transient ischemic attack provide a rationale for future trials of improved thrombus aspiration technologies in this high-risk subgroup.

- Aims: Preliminary studies suggest that direct stenting (DS) during percutaneous coronary intervention (PCI) may reduce microvascular obstruction and improve clinical outcome. Thrombus aspiration may facilitate DS. We assessed the impact of DS on clinical outcome and myocardial reperfusion and its interaction with thrombus aspiration among ST-segment elevation myocardial infarction (STEMI) patients undergoing PCI.Methods and results: Patient-level data from the three largest randomized trials on routine manual thrombus aspiration vs. PCI only were merged. A 1:1 propensity matched population was created to compare DS and conventional stenting. Synergy between DS and thrombus aspiration was assessed with interaction P-values in the final models. In the unmatched population (n= 17329), 32% underwent DS and 68% underwent conventional stenting. Direct stenting rates were higher in patients randomized to thrombus aspiration as compared with PCI only (41% vs. 22%; P < 0.001). Patients undergoing DS required less contrast (162 mL vs. 172 mL; P < 0.001) and had shorter fluoroscopy time (11.1 min vs. 13.3 min; P < 0.001). After propensity matching (n = 10944), no significant differences were seen between DS and conventional stenting with respect to 30-day cardiovascular death [1.7% vs. 1.9%; hazard ratio 0.88, 95% confidence interval (CI) 0.55-1.41; P=0.60; P-interaction = 0.96) and 30-day stroke or transient ischaemic attack (0.6% vs. 0.4%; odds ratio 1.02; 95% CI 0.14-7.54; P= 0.99; P-interaction = 0.81). One-year results were similar. No significant differences were seen in electrocardiographic and angiographic myocardial reperfusion measures.Conclusion: Direct stenting rates were higher in patients randomized to thrombus aspiration. Clinical outcomes and myocardial reperfusion measures did not differ significantly between DS and conventional stenting and there was no interaction with thrombus aspiration.

- Background: Women have a worse prognosis after ST-segment elevation myocardial infarction (STEMI) than men. The prognostic role of thrombus burden (TB) in influencing the sex-related differences in clinical outcomes after STEMI has not been clearly investigated.Objectives: The aim of this study was to assess the sex-related differences in TB and its clinical implication in patients with STEMI.Methods: We analyzed individual patient data from the 3 major randomized clinical trials of manual thrombus aspiration, encompassing a total of 19,047 patients with STEMI, of whom 13,885 (76.1%) were men and 4,371 (23.9%) were women. The primary outcome of interest was 1-year cardiovascular (CV) death. The secondary outcomes of interest were recurrent myocardial infarction, heart failure, all-cause mortality, stroke, stent thrombosis (ST), and target vessel revascularization at 1 year.Results: Patients with high TB (HTB) had worse 1-year outcomes compared with those presenting with low TB (adjusted HR for CV death; 1.52; 95% CI: 1.10-2.12; P=0.01). In unadjusted analyses, female sex was associated with an increased risk for 1-year CV death regardless of TB. After adjustment, this risk for 1-year CV death was higher only in women with HTB (HR 1.23, 95% CI: 1.18-1.28; P<0.001) who also had an increased risk for all-cause death and ST than men.Conclusion: In patients with STEMI, angiographic evidence of HTB negatively affected prognosis. Among patients with HTB, women had an excess risk for stent thrombosis, CV and all-cause mortality than men. Further investigations are warranted to better understand the pathophysiological mechanisms leading to excess mortality in women with STEMI and HTB.

- ABSTRACT : INTRODUCTION : Blood lactate measurements can be used as an indicator of hemodynamic impairment and relate to mortality in various forms of shock. Little is known at the moment concerning the clinical correlates of systemic lactate in patients with ST-segment elevation myocardial infarction (STEMI). METHODS : To assess the relation of systemic arterial lactate levels in STEMI patients with clinical correlates at presentation in the catheterization laboratory, we measured arterial lactate levels with a rapid point-of-care technique, immediately following femoral sheath insertion. The study population (n= 1,176) was divided into tertiles with lactate levels ≤1.1 (n = 410), 1.2 to 1.7 (n = 398) and ≥1.8 mmol/l (n = 368). We compared both baseline characteristics and outcome measures of the three lactate groups. RESULTS : Factors independently associated with higher lactate levels were hypotension, heart rate, thrombolysis in myocardial infarction (TIMI) flow 0 to 1, diabetes and non-smoking. Mortality at 30 days in the three groups was 2.0%, 1.5% and 6.5%. The latter group also showed lower blush grades and greater enzymatic infarct sizes. An intra aortic balloon pump (IABP) was used more frequently in patients with higher lactate levels (4.2%, 7.6% and 14.7%). CONCLUSIONS : In STEMI patients, impaired hemodynamics, worse TIMI flow and non-smoking were related to increased arterial lactate levels. Higher lactate levels were independently related with 30-day mortality and an overall worse response to percutaneous coronary intervention (PCI). In particular, acute mortality was related to admission lactates ≥1.8 mmol/L. Point-of-care measurement of arterial lactate at admission in patients with STEMI has the potential to improve acute risk stratification.

- Quality indicators in cardiology can be used to guide performance at a patient level, or at an organizational level. To positively influence adherence to performance guidelines, policymakers have to ensure that employees are involved in the development of guidelines and indicators. The first phase for selecting performance measures is creating a set of performance indicators. The aim of this study was to identify performance indicators with a high degree of consensus among professionals in daily practice for interventional cardiology. Each of the 50 predefined performance indicators was rated by 17 cardiologists and 17 head nurses (one from each participating center) on a 5-point scale. The cluster of indicators with the highest scores was resubmitted to the participants of the first phase for verification. After the second phase, performance indicators with >90% positive score for inclusion were qualified as key performance indicator (KPI). In the first phase, 24 of 34 response forms were returned (71%). Performance indicators with the highest overall mean scores were complications (4.71), in-hospital delay for patients with acute myocardial infarction (4.67), mortality (4.63), technical result (4.42), and patient satisfaction (4.38). The scores of cardiologists and nurses showed similar patterns. Nineteen indicators were selected for verification. After the second phase, 8 indicators qualified as KPI: complications, data flow, in-hospital delay, frequency of heart team meetings, number of procedures per center, mortality, restenosis rate, and use of protocols. The 8 KPI are both quantifiable and aimed at the catheterization laboratory as a unit.
