RESUMEN
BACKGROUND: Current guidelines emphasize the diagnostic value of non-cardiac or possibly cardiac chest pain. The goal of this analysis was to determine whether German chest pain units (CPUs) adequately address conditions with "atypical" chest pain in existing diagnostic structures. METHOD: A total of 11,734 patients from the German CPU registry were included. The analyses included mode of admission, critical time intervals, diagnostic steps, and differential diagnoses. RESULTS: Patients with unspecified chest pain were younger, more often female, were less likely to have classic cardiovascular risk factors and tended to present more often as self-referrals. Patients with acute coronary syndrome (ACS) mostly had prehospital medical contact. Overall, there was no difference between these two groups regarding the time from the onset of first symptoms to arrival at the CPU. In the CPU, the usual basic diagnostic measures were performed irrespective of ACS as the primary working diagnosis. In the non-ACS group, further ischemia-specific diagnostics were rarely performed. Extra-cardiac differential diagnoses were not specified. CONCLUSION: The establishment of broader awareness programs and opening CPUs for low-threshold evaluation of self-referring patients should be discussed. Regarding the rigid focus on the clarification of cardiac causes of chest pain, a stronger interdisciplinary approach should be promoted.

Tobacco smoking is the greatest preventable health risk. The effects are serious, both individually and societal. Nevertheless, the current prevalence of tobacco smokers in Germany is still high at around 35â%. A recent strong increase in actively smoking adolescents (14- to 17-year-olds, current prevalence approx. 16â%) and young adults (18- to 24-year-olds, current prevalence approx. 41â%) is also a cause for concern. About a third of all inpatients continue smoking while being treated. The hospitalization of active smokers in acute and rehabilitation hospitals serves as a "teachable moment" for initiation of cessation offers. An intervention that begins in hospital and continues for at least a month after discharge results in about 40â% additional smokefree patients. It is scientifically well-researched, effective and cost-efficient. After initiation in hospital these measures can be continued via ambulatory cessation programs, rehabilitation facilities, an Internet or telephone service. In Germany, there are structured and quality-assured cessation offers, both for the inpatient and for the outpatient area. The biggest obstacle to broad establishment of such offers is the lack of reimbursement. Two feasible ways to change this would be the remuneration of the existing OPS 9-501 "Multimodal inpatient treatment for smoking cessation" and the establishment of quality contracts according to §â110a SGB V. An expansion of tobacco cessation measures in healthcare facilities would reduce smoking prevalence, associated burden of disease and consecutive costs.

Problem: Reducing risk by improving fitness is one of the main objectives of cardiac rehabilitation (CR). To estimate how the number of steps/day post-CR affects coronary patients' prognosis, we analyzed its correlation with the occurrence of death, hospitalizations, and heart complaints, and if and how other variables (ejection fraction (EF), gender, age) relate to those. Methods: One hundred eleven patients (male = 91, female = 20; average age ± standard deviation (SD): 61 ± 11 years) who had been in CR due to recent coronary revascularization or chronic coronary syndrome could be enrolled. Patients were advised to document their steps (daily), blood pressure (daily), weight (weekly) and occurrences of a cardiac event in a diary for 1 year post-CR. A Cox proportional hazard model was used to examine the influence of steps/day, EF, gender, and age until the occurrence of an event. Kaplan-Meier curves were generated to compare patients' profiles. Results: Average steps/day of patients post-CR were 7333 (SD 4426). Increased walking activity reduced risk for cardiac hospitalization (constant steps/day: 5000 vs 7500, hazard rate (HR) reduction of 0.43; 10 000 vs 12 500, HR reduction of 0.20) and risk was higher in patients with an EF < 55% versus EF ⩾ 55% (HR increase of 2.88). Median follow-up time post-CR was 218 days. No patient died, 25 were hospitalized. Discussion: Monitoring the number of steps of coronary patients post CR could be valuable for estimating patients' prognosis.

BACKGROUND: We aimed to analyze the 2020 standard of care in certified German chest pain units (CPU) with a special focus on non-ST-segment elevation acute coronary syndrome (NSTE-ACS) through a voluntary survey obtained from all certified units, using a prespecified questionnaire. METHODS: The assessment included the collection of information on diagnostic protocols, risk assessment, management and treatment strategies in suspected NSTE-ACS, the timing of invasive therapy in non-ST-segment elevation myocardial infarction (NSTEMI), and the choice of antiplatelet therapy. RESULTS: The response rate was 75%. Among all CPUs, 77% are currently using the European Society of Cardiology (ESC) 0/3h high-sensitive troponin protocol, and only 20% use the ESC 0/1h high-sensitive troponin protocol as a default strategy. Conventional ergometry is still the commonly performed stress test with a utilization rate of 47%. Among NSTEMI patients, coronary angiography is planned within 24â¯h in 96% of all CPUs, irrespective of the day of the week. Prasugrel is the P2Y12 inhibitor of choice in ST-segment elevation myocardial infarction (STEMI), but despite the impact of the ISAR-REACT 5 trial on selection of antiplatelet therapy, ticagrelor is still favored over prasugrel in NSTE-ACS. If triple therapy is used in NSTE-ACS with atrial fibrillation, it is maintained up to 4 weeks in 51% of these patients. CONCLUSION: This survey provides evidence that Germany's certified CPUs ensure a high level of guideline adherence and quality of care. The survey also identified areas in need of improvement such as the high utilization rate of stress electrocardiogram (ECG).

AIMS: Early heart attack awareness programs are thought to increase efficacy of chest pain units (CPU) by providing live-saving information to the community. We hypothesized that self-referral might be a feasible alternative to activation of emergency medical services (EMS) in selected chest pain patients with a specific low-risk profile. METHODS AND RESULTS: In this observational registry-based study, data from 4743 CPU patients were analyzed for differences between those with or without severe or fatal prehospital or in-unit events (out-of-hospital cardiac arrest and/or in-unit death, resuscitation or ventricular tachycardia). In order to identify a low-risk subset in which early self-referral might be recommended to reduce prehospital critical time intervals, the Global Registry of Acute Coronary Events (GRACE) score for in-hospital mortality and a specific low-risk CPU score developed from the data by multivariate regression analysis were applied and corresponding event rates were calculated. Male gender, cardiac symptoms other than chest pain, first onset of symptoms and a history of myocardial infarction, heart failure or cardioverter defibrillator implantation increased propensity for critical events. Event rates within the low-risk subsets varied from 0.5-2.8%. Those patients with preinfarction angina experienced fewer events. CONCLUSIONS: When educating patients and the general population about angina pectoris symptoms and early admission, activation of EMS remains recommended. Even in patients without any CPU-specific risk factor, self-referral bears the risk of severe or fatal pre- or in-unit events of 0.6%. However, admission should not be delayed, and self-referral might be feasible in patients with previous symptoms of preinfarction angina.

OBJECTIVES: We assessed possible myocardial involvement in previously cardiac healthy post-COVID patients referred for persisting symptoms with suspected myocarditis. BACKGROUND: Prior studies suggested myocardial inflammation in patients with coronavirus-induced disease 2019 (COVID-19). However, the prevalence of cardiac involvement among COVID patients varied between 1.4 and 78%. METHODS: A total of 56 post-COVID patients without previous heart diseases were included consecutively into this study. All patients had positive antibody titers against SARS-CoV-2. Patients were referred for persistent symptoms such as chest pain/discomfort, shortness of breath, or intolerance to activity. All patients underwent standardized cardiac assessment including electrocardiogram (ECG), cardiac biomarkers, echocardiography, and cardiac magnetic resonance (CMR). RESULTS: 56 Patients (46 ± 12 years, 54% females) presented 71 ± 66 days after their COVID-19 disease. In most patients, the course of COVID-19 was mild, with hospital treatment being necessary in five (9%). At presentation, patients most often reported persistent fatigue (75%), chest pain (71%), and shortness of breath (66%). Acute myocarditis was confirmed by T1/T2-weighed CMR and elevated NTpro-BNP levels in a single patient (2%). Left ventricular ejection fraction was 56% in this patient. Additional eight patients (14%) showed suspicious CMR findings, including myocardial edema without fibrosis (n = 3), or non-ischemic myocardial injury suggesting previous inflammation (n = 5). However, myocarditis could ultimately not be confirmed according to 2018 Lake Louise criteria; ECG, echo and lab findings were inconspicuous in all eight patients. CONCLUSIONS: Among 56 post-COVID patients with persistent thoracic complaints final diagnosis of myocarditis could be confirmed in a single patient using CMR.

INTRODUCTION: Since 2008, specialized chest pain units (CPUs) were implemented across Germany ensuring structured diagnostics in acute chest pain. This study aims to analyze the management of pulmonary embolism (PE) patients in such certified CPUs. METHODS: Data were retrieved from 13,902 patients enrolled in the German CPU registry and analyzed for the diagnosis of PE including patient characteristics, critical time intervals, diagnostic workup, treatment, and prognosis. PE patients were compared to the overall CPU patient cohort. Only patients with a complete 3-month follow-up were included. RESULTS: Overall, 1.1% of all CPU patients were diagnosed with PE. Chest pain and dyspnea were the leading symptoms. Patients with PE were older, presented with higher heart rates, and more frequently exhibited signs of heart failure, despite a normal left ventricular function. PE patients showed significantly longer time delays between symptom onset and the first medical contact, while PE patients with chest pain presented earlier than PE patients with dyspnea only. Whereas more PE patients had to be transferred to the intensive care unit, in-CPU mortality and event rates over 3 months were low. DISCUSSION/CONCLUSION: This study suggests a certain risk for underdiagnosis and consecutive potential undertreatment of PE patients in German Cardiac Society (GCS)-certified CPUs, which is thought to result from an anticipated focus on patients with acute coronary syndrome (ACS). Public awareness for PE beyond chest pain should be improved. Certified CPUs should be urged to implement strategic pathways for a better simultaneous diagnostic workup of differential diagnosis beyond ACS.

BACKGROUND: In modern cardiology, anticoagulation and antiaggregation are key components of current treatment strategies. However, in patients treated with anticoagulation and antiplatelet substances, bleeding is a major risk. FINDINGS: In all major cardiovascular diseases, a multitude of studies have shown a positive impact of antithrombotic treatment on cardiovascular death. In patients with higher bleeding risks, recent studies showed the safety of reducing the period of dual antiplatelet therapy (DAPT), i.e., after percutaneous coronary intervention. In patients with coronary artery disease and atrial fibrillation (AF), triple therapy including DAPT and anticoagulation is associated with very high bleeding risks. However, recently published data showed the safety of direct oral anticoagulants (DOACs) and P2Y12 inhibitors only compared to vitamin K antagonist (VKA) and DAPT. Anticoagulation in nonvalvular AF reduces major cerebrovascular ischemic events. However, the inherent cerebrovascular bleeding risk is an important concern of this treatment. With the advent of DOACs, this risk could be reduced compared to VKA. Furthermore, anticoagulation and antiaggregation are crucial after treatment of valve disease, both after surgical and interventional procedures. Even in heart failure, new data show benefits using antithrombotic substances. CONCLUSIONS: Anticoagulation and antiaggregation are of major prognostic relevance in cardiovascular diseases. However, the inherent bleeding risk has to be considered.
RESUMEN
INTRODUCTION: Gender-specific atypical clinical presentation in acute coronary syndrome and sex-specific outcomes in cardiovascular disease in women are well known. The aim of this study is to analyze possible differences between men and women presenting to certified German chest pain units (CPUs). METHODS: Data from 13,900 patients derived from the German CPU registry were analyzed for gender differences in patient characteristics, cardiovascular disease manifestation, critical time intervals, treatment and prognosis. RESULTS: A total of 37.8% of patients were female. Typical chest pain occurred more frequently in men, while atypical symptoms occurred more frequently in women. Female gender was associated with longer pre- and in-hospital time delays. Women were more often diagnosed with a nonischemic origin of pain. In a 3-month follow-up, there was no gender-specific difference in combined major adverse coronary and cerebrovascular events. DISCUSSION/CONCLUSION: This study points out gender-specific differences in prehospital time intervals and a significantly higher percentage of atypical symptoms in suspected myocardial ischemia as well as more noncoronary diagnoses in women. Symptom awareness and a broader diagnostic workup in women are essential.

BACKGROUND: Since 2008, the German Cardiac Society certified 256 Chest Pain Units (CPUs). Little is known about adherence to recommended performance measures in patients with suspected acute coronary syndrome (ACS) presenting to CPUs. We investigated guideline-adherence regarding critical time intervals and selected performance measures in German Chest Pain Units. METHODS: From 2008 to 2014, 23,804 consecutive patients with suspected ACS were prospectively enrolled in the Chest Pain Unit registry of the German Cardiac Society. RESULTS: Median time from symptom onset to first medical contact was 2 h in patients with ST-elevation myocardial infarction (STEMI) and 4 h in patients with unstable angina and non-STEMI (NSTEMI). In patients with STEMI, median time from hospital admission to percutaneous coronary intervention (PCI) was 40 min and median time from first medical contact to PCI was 1 h 35 min. Primary PCI was performed in 94.7% of patients with STEMI, 70.0% of patients with NSTEMI and 37.4% of patients with unstable angina. PCI was performed during the first 24 h in 79.5% of patients with NSTEMI and the first 72 h in 89.0% of patients with unstable angina. Electrocardiograms were performed in 99.5% after a median of 6 min after admission and obtained within 10 min in 71%. Interestingly, 56.1% of patients were found to have non-ACS diagnoses, underlining the importance of access to additional diagnostic modalities including echocardiography, stress testing or computed tomography. CONCLUSIONS: Guideline-adherence regarding critical time intervals and primary PCI rates is good in German Chest Pain Units. More than half of patients admitted with suspected ACS had non-ACS diagnoses. Improvements in pre-hospital time delays through public awareness programmes are warranted.

BACKGROUND: A total of 6,500 to 8,000 steps per day are recommended for cardiovascular secondary prevention. The aim of this research was to examine how many steps per day patients achieve during ambulant cardiac rehabilitation (CR), and if there is a correlation between the number of steps and physical and cardiological parameters. METHODS: In all, 192 stable CR patients were included and advised for sealed pedometry. The assessed parameters included maximum working capacity and heart rate, body mass index (BMI), New York Heart Association (NYHA) class, ejection fraction (EF), coronary artery disease status, beta-blocker medication, age, sex, smoking behavior, and laboratory parameters. A regularized regression approach called least absolute shrinkage and selection operator (LASSO) was used to detect a small set of explanatory variables associated with the response for steps per day. Based on these selected covariates, a sparse additive regression model was fitted. RESULTS: The model noted that steps per day had a strong positive correlation with maximum working capacity (P=0.001), a significant negative correlation with higher age (P=0.01) and smoking (smoker: P<0.05; ex-smoker: P=0.01), a positive correlation with high-density lipoprotein (HDL), and a negative correlation with beta-blockers. Correlation between BMI and walking activity was nonlinear (BMI 18.5-24: 7,427±2,730 steps per day; BMI 25-29: 6,448±2,393 steps/day; BMI 30-34: 6,751±2,393 steps per day; BMI 35-39: 5,163±2,574; BMI >40: 6,077±1,567). CONCLUSION: Walking activity during CR is reduced in patients who are unfit, older, smoke, or used to smoke. In addition to training recommendations, estimated steps per day during CR could be seen as a baseline orientation that helps patients to stay generally active or even to increase activity after CR.

In patients with stable symptoms suggestive of coronary artery disease (CAD), coronary CT angiography (CTA) allows for assessing several aspects of coronary atherosclerosis. Coronary artery stenoses are reliably detected, plaque formation can be quantified and characterized as calcified or non-calcified, and markers of potential instability such as expansive vascular remodeling, spotty calcification, and atheroma size can be described. As opposed to invasive coronary angiography, CTA visualizes the vessel lumen and wall. Being a purely anatomic test, even small plaques are detected with excellent sensitivity. At the other end of the spectrum, the hemodynamic significance of large plaque burden is sometimes overestimated. This may in part be corrected using mathematical modeling. Computational fluid dynamics of vascular anatomy and subtended myocardial mass provide for measures of CT-based fractional flow reserve (FFRCT). Large prospective trials have demonstrated the diagnostic utility of CTA in particular for ruling out obstructive CAD. The ability to detect non-obstructive plaque allows for improved risk prediction in comparison with functional testing, because even patients with sub-clinical atherosclerosis can be identified and selected for preventive medical treatment. This has led to incorporating CTA as one of several possible diagnostic tests for the evaluation of stable CAD in the actual European guidelines. Recently, it has even been forwarded as the first-line diagnostic test in the United Kingdom. The clinical implications of novel quantitative CTA-derived parameters such as FFRCT and non-calcified plaque volume are being examined in ongoing studies.

AIMS: Randomised trials comparing transcatheter aortic valve replacement (TAVR) with surgical aortic valve replacement (SAVR) have included mainly elderly patients >80 years. The authors investigated comparative in-hospital outcomes of younger patients <75 years undergoing transfemoral (TF) TAVR or isolated SAVR. METHODS AND RESULTS: A total of 6,972 patients aged 65-74 years undergoing TF-TAVR or SAVR between 2013 and 2014 were identified from the observational German Quality Assurance Registry on Aortic Valve Replacement (AQUA), which comprises all TAVR and SAVR procedures performed in Germany. Analyses were performed for the overall unmatched cohort as well as for 1,388 propensity-matched patients. Overall, 82.4% of patients <75 years needing treatment for aortic valve stenosis received SAVR. Patients undergoing TF-TAVR were older and had more comorbidities with higher predicted risk of death. After propensity-matching, in-hospital mortality (1.3% vs. 1.9%, p=0.39), neurologic complications (1.0% vs. 2.1%, p=0.09), and myocardial infarctions (0 vs. 0.3%, p=0.16) were not different after TF-TAVR or SAVR. Postoperative delirium was more frequent after SAVR (8.9% vs. 2.4%, p<0.001), whereas the need for new pacemaker was 4 times higher after TF-TAVR (13.3% vs. 3.5%, p<0.001). CONCLUSIONS: Younger patients <75 years undergoing TF-TAVR or SAVR had similar outcomes with the exception of more frequent need for new pacemaker implantation and less frequent incidence of post-operative dialysis and delirium in TF-TAVR patients. Whether these similar in-hospital outcomes are replicable in the longer-term events in TF-TAVR and SAVR remains to be proven in future studies.

BACKGROUND: Patients with non ST-segment elevation myocardial infarction (NSTEMI) represent the largest fraction of patients with acute coronary syndrome in German Chest Pain units. Recent evidence on early vs. selective percutaneous coronary intervention (PCI) is ambiguous with respect to effects on mortality, myocardial infarction (MI) and recurrent angina. With the present study we sought to investigate the prognostic impact of PCI and its timing in German Chest Pain Unit (CPU) NSTEMI patients. METHODS AND RESULTS: Data from 1549 patients whose leading diagnosis was NSTEMI were retrieved from the German CPU registry for the interval between 3/2010 and 3/2014. Follow-up was available at median of 167days after discharge. The patients were grouped into a higher (Group A) and lower risk group (Group B) according to GRACE score and additional criteria on admission. Group A had higher Killip classes, higher BNP levels, reduced EF and significant more triple vessel disease (p<0.001). Surprisingly, patients in group A less frequently received early diagnostic catheterization and PCI. While conservative management did not affect prognosis in Group B, higher-risk CPU-NSTEMI patients without PCI had a significantly worse survival. CONCLUSIONS: The present results reveal a substantial treatment gap in higher-risk NSTEMI patients in German Chest Pain Units. This treatment paradox may worsen prognosis in patients who could derive the largest benefit from early revascularization.

BACKGROUND: Direct transfer to the catheterization laboratory for primary percutaneous coronary intervention (PCI) is standard of care for patients with ST-segment elevation myocardial infarction (STEMI). Nevertheless, a significant number of STEMI-patients are initially treated in chest pain units (CPUs) of admitting hospitals. Thus, it is important to characterize these patients and to define why an important deviation from recommended clinical pathways occurs and in particular to quantify the impact of deviation on critical time intervals. METHODS AND RESULTS: 1679 STEMI patients admitted to a CPU in the period from 2010 to 2015 were enrolled in the German CPU registry (8.5% of 19,666). 55.9% of the patients were delivered by an emergency medical system (EMS), 16.1% transferred from other hospitals and 15.2% referred by a general practitioner (GP). 12.7% were self-referrals. 55% did not get a pre-hospital ECG. Compared to the EMS, referral by GPs markedly delayed critical time intervals while a pre-hospital ECG demonstrating ST-segment elevation reduced door-to-balloon time. When compared to STEMI patients (n=21,674) enrolled in the ALKK-registry, CPU-STEMI patients had a lower risk profile, their treatment in the CPU was guideline-conform and in-hospital mortality was low (1.5%). CONCLUSIONS: CPU-STEMI patients represent a numerically significant group because a pre-hospital ECG was not documented. Treatment in the CPU is guideline-conform and the intra-hospital mortality is low. The lack of a pre-hospital ECG and admission via the GP substantially delay critical time intervals suggesting that in patients with symptoms suggestive an ACS, the EMS should be contacted and not the GP.

BACKGROUND: Regional healthcare projects improve the off-hour care of patients with acute coronary syndromes and persistent ST-segment elevation myocardial infarction (STEMI). To analyse differences in quality of care between on and off-hour care of STEMI patients admitted to certified German chest pain units. METHODS: A total of 1107 STEMI patients from the German chest pain unit registry were enrolled. Analyses comprised critical time intervals (symptoms to first medical contact (FMC), FMC to admission, symptoms to admission, symptoms to balloon, FMC to balloon, door to balloon times) and major adverse cardiac and cerebrovascular events at follow-up. RESULTS: 54.8% of patients were admitted off-hours. Symptoms to admission (2:28 (1:28-5:20 h) vs. 3:16 h (1:35-8:06 h), P<0.001), symptoms to FMC (1:15 h (0:33-3:00 h) vs. 2:00 h (0:40-6:46 h), P<0.001) and FMC to admission intervals (0:45 h (0:30-1:20 h) vs. 0:52 h (0:32-1:35 h), P=0.09) were shorter during off-hours. Percutaneous revascularisation rates were high and without difference between on and off-hours (95.5% vs. 96.8%, P=0.30). Door to balloon times were significantly less during on-hours (0:32 h (0:18-1:06 h) vs. 0:44 h (0:23-1:20 h), P<0.01) without negative impact on the proportion of patients with a door to balloon time of <60 min (72.6% vs. 68.4%, P=0.19), symptoms to balloon (3:49 h (2:12-10:46 h) vs. 3:30 h (2:04-7:41 h), P=0.08) or FMC to balloon times (1:26 h (0:56-2:22 h) vs. 1:30 h (1:03-2:29 h), P=0.14). Major adverse cardiac and cerebrovascular event rates did not differ significantly between on and off-hours (log-rank test P=0.36). CONCLUSIONS: The German chest pain unit network ensures rapid and structured preclinical and in-hospital care independent from the circadian variation of admission. Slower door to balloon times off-hours are compensated by faster symptoms to admission or symptoms to FMC intervals. Further efforts should focus on patient awareness programmes on-hours and STEMI alarming tracks off-hours.

AIMS: Performing transcatheter aortic valve implantation (TAVI) at hospitals with only cardiology department but no cardiac surgery (CS) on-site is at great odds with current Guidelines. METHODS AND RESULTS: We analysed data from the official, prospective German Quality Assurance Registry on Aortic Valve Replacement to compare characteristics and in-hospital outcomes of patients undergoing transfemoral TAVI at hospitals with (n = 75) and without CS departments (n = 22). An interdisciplinary Heart Team was established at all centres (internal staff physicians at hospitals with on-site CS; in-house cardiologists and visiting cardiac surgical teams from collaborating hospitals at non-CS hospitals). In 2013 and 2014, 17 919 patients (81.2 ± 6.1 years, 55% females, German aortic valve (GAV) score 2.0 5.6 ± 5.8%, logistic EuroSCORE I 21.1 ± 15.4%) underwent transfemoral TAVI in Germany: 1332 (7.4%) at hospitals without on-site CS department. Patients in non-CS hospitals were older (82.1 ± 5.8 vs. 81.1 ± 6.1 years, P < 0.001), with more frequent co-morbidities. Predicted mortality risks per GAV-score 2.0 (6.1 + 5.5 vs. 5.5 ± 5.9%, P < 0.001) and logEuroSCORE I (23.2 ± 15.8 vs. 21.0 ± 15.4%, P < 0.001) were higher in patients at non-CS sites. Complications, including strokes (2.6 vs. 2.3%, P = 0.452) and in-hospital mortality (3.8 vs. 4.2%, P = 0.396), were similar in both groups. Matched-pair analysis of 555 patients in each group with identical GAV-score confirmed similar rates of intraprocedural complications (9.2 vs. 10.3%, P = 0.543), strokes (3.2% for both groups, P = 1.00), and in-hospital mortality (1.8 vs. 2.9%, P = 0.234). CONCLUSION: Although patients undergoing TAVI at hospitals without on-site CS department were older and at higher predicted perioperative death risk, major complications, and in-hospital mortality were not statistically different, suggesting the feasibility and safety of Heart Team-based TAVI at non-CS sites. These findings need confirmation in future randomized study.

OBJECTIVES: To analyze the current usage of transthoracic echocardiography (TTE) as a rapid, noninvasive tool in the early stratification of acute chest pain in certified German chest pain units (CPUs). METHODS: A total of 23,997 patients were enrolled. Analyses comprised TTE evaluation rates in relation to clinical presentation, risk profile, left ventricular impairment, final diagnosis and invasive management. Critical times were assessed. Multivariable analyses for independent determinants for the use of TTE were performed. RESULTS: TTE evaluation was available in CPUs in 70.1% of cases. It was associated with lower rates of invasive management in unstable angina pectoris (UAP) and with higher rates in patients with initially suspected non-cardiac origin of symptoms and/or reduced systolic function (p < 0.05). Non-ST-segment elevation acute coronary syndrome (NSTE-ACS) was an independent determinant favoring TTE evaluation [NSTE-myocardial infarction: odds ratio (OR) 1.62; UAP: OR 1.34; p < 0.001 for both]. Clinical signs of heart failure (OR 1.31; p < 0.001), referral by emergency medical service (OR 1.18; p < 0.001) and kidney failure (OR 1.16; p < 0.05) were independently associated with higher TTE rates. TTE did not delay door-to-balloon times. CONCLUSIONS: About two thirds of the patients admitted to certified CPUs received TTE evaluation, with the highest rates being in ACS patients, and thereby providing diagnostic information supporting or refuting further invasive management.
