RESUMEN
Introduction: The aim of this study was to analyze age-associated myocardial injury and clinical outcome after non-ST-elevation myocardial infarction (NSTEMI). Methods: This prospective, multicenter study consists of 440 patients with NSTEMI enrolled at 7 centers. All patients were treated with primary percutaneous coronary intervention and underwent cardiac magnetic resonance (CMR) imaging 1-10 days after study inclusion. CMR parameters of myocardial injury and clinical outcome were evaluated by creating 2 subgroups: <80 years vs. ≥80 years. The clinical endpoint was the 1-year incidence of major adverse cardiac events (MACE) consisting of death, re-infarction and new congestive heart failure. Results: Elderly patients ≥80 years accounted for 13.9% of the study population and showed a divergent cardiovascular risk profile compared to the subgroup of patients <80 years. CMR imaging did not reveal significant differences regarding infarct size, microvascular obstruction, left ventricular ejection fraction or multidimensional strain analysis between the study groups. At 1-year follow-up, MACE rate was significantly increased in patients ≥80 years compared to patients aged <80 years (19.7% vs. 9.6%; p = 0.019). In a multiple stepwise logistic regression model, the number of diseased vessels, aldosterone antagonist use and left ventricular global longitudinal strain were identified as independent predictors for MACE in all patients, while there was no independent predictive value of age regarding 1-year clinical outcome. Conclusion: This prospective, multicenter analysis shows that structural and functional myocardial damage is similar in younger and older patients with NSTEMI. Furthermore, in this heterogeneous but also clinically representative cohort with reduced sample size, age was not independently associated with 1-year clinical outcome, despite an increased event rate in patients ≥80 years.
RESUMEN
Background: Supersaturated oxygen (SSO2) delivered into the left anterior descending coronary artery after percutaneous coronary intervention (PCI) for anterior ST-segment elevation myocardial infarction (STEMI) has been shown to reduce infarct size, but its effects on microvascular obstruction (MVO) are unknown. The aim of this study was to compare MVO in patients with anterior STEMI treated with SSO2 after successful primary PCI from 2 studies (the optimized SSO2 pilot and IC-HOT) with similar patients from 7 randomized trials who underwent primary PCI without SSO2 treatment. Methods: A total of 874 patients with anterior STEMI who underwent MVO assessment using cardiac magnetic resonance imaging within 10 days after primary PCI were included, of whom 90 patients (10.3%) were treated with SSO2. The primary end point was the extent of MVO as a continuous measure in a weighted multivariable model. The secondary end point was the presence of MVO. Results: SSO2 therapy was independently associated with a lower extent of MVO compared with no SSO2 therapy (coefficient, -1.35; 95% CI, -2.58 to -0.11; P = .03). SSO2 therapy was also associated with a borderline lower risk of any MVO (adjusted odds ratio, 0.56; 95% CI, 0.31-1.00; P = .051). Conclusions: In the present individual patient data pooled analysis from 9 studies, SSO2 therapy was associated with less MVO after successful primary PCI for anterior STEMI.
RESUMEN
OBJECTIVES: Right heart catheterization (RHC) is a common diagnostic tool and of special importance in the diagnosis of pulmonary hypertension (PH). Until today, there have been no clear instructions or guidelines on which venous access to prefer. This meta-analysis assessed whether the choice of the venous access site for elective RHC has an impact on procedural or clinical outcomes. METHODS: A structured literature search was performed. Single-arm reports and controlled trials reporting event data were eligible. The primary endpoint was a composite of access-related and overall complications. RESULTS: Nineteen studies, including 6509 RHC procedures, were eligible. The results were analyzed in two groups. The first group compared central venous access (CVA; n = 2072) with peripheral venous access (PVA; n = 2680) and included only multi-arm studies (n = 12, C/P comparison). In the second group, all studies (n = 19, threeway comparison) were assessed to compare the three individual access ways. The overall complication rate was low at 1.0% (n = 68). The primary endpoint in the C/P comparison occurred significantly less for PVA than for CVA (0.1% vs. 1.2%; p = 0.004). In the threeway comparison, PVA had a significantly lower complication rate than femoral access (0.3% vs. 1.1%; p = 0.04). Jugular access had the numerically highest complication rate (2.0%), but the difference was not significant compared to peripheral (0.3%; p = 0.29) or femoral access (1.1%; p = 0.32). CONCLUSION: This meta-analysis showed that PVA for RHC has a significantly lower complication rate than CVA. There was a low level of certainty and high heterogeneity. This pooled data analysis indicated PVA as the primary venous access for RHC.
RESUMEN
Atrial fibrillation (AF) is the most common rhythm disorder with a high risk for cardioembolic strokes. Interventional occlusion of the left atrial appendage (LAA) is an alternative to the widely established stroke prevention with oral anticoagulation. Complications through LAA closure (LAAC) are rare and usually occur periinterventional. We present a case of an 87-year-old patient who presents for elective LAAC. After placement of the LAA occluder (Amplatzer Amulet device 25 mm) in the LAA and partial resheathing, the patient developed a pericardial effusion (PE), became hemodynamically unstable and went into cardiac arrest with the need for cardiopulmonary resuscitation (CPR). After drainage of the PE, we closed the causative LAA-perforation using a persistent foramen ovale (PFO)-occluder device (Amplatzer Talisman, 25 mm). Thereby we were able to successfully seal the perforation and stabilize the patient. The patient was monitored at our intensive care unit for 2 days and left the hospital in good condition a few days after. Procedural complications during interventional LAAC are rare but can be serious. The most common complication, PE, requires percutaneous drainage and often cardiac surgery. We present a case in which a perforation and following PE with hemodynamic relevance and need for CPR was resolved with an interventional strategy through implantation of a PFO-occluder into the perforation. With this approach we were able to show that in the right setting even serious complications can be treated by interventional measures, thereby not only saving the patient's life, but also avoiding cardiac surgery.
RESUMEN
Background: Besides transcatheter edge-to-edge repair (TEER), there are new interventional treatment options for mitral and tricuspid regurgitation in evaluation, such as a complete replacement of the valve through a prosthesis. Case summary: A 78-year-old previous coronary artery bypass graft-operated patient with symptomatic severe mitral regurgitation and tricuspid regurgitation was sequentially treated by a transfemoral transcatheter mitral and tricuspid valve prosthesis (Cardiovalve; Cardiovalve Ltd, Israel) due to unfavourable mitral valve anatomy. The transcatheter mitral valve implantation (TMVI) was performed first and after progression of the tricuspid regurgitation, a second transcatheter valve prosthesis was implanted in tricuspid position (TTVI) 1.5 years later. Imaging showed a twin look-alike picture of a mitral and tricuspid prosthesis and showing the possibility of a complete transcatheter based replacement of the mitral and tricuspid valve. Discussion: This case shows the possibility of a Cardiovalve prosthesis being used for TMVI and TTVI in a single patient. Especially in TEER ineligible patients, it might be a good treatment option after device approval.
RESUMEN
BACKGROUND: International guidelines emphasize the importance of preventive efforts after early-onset myocardial infarction (EOMI); however, data on "real-world" long-term risk factor management and adverse event rates in this special patient group is scarce. METHODS: In this German registry study, 301 patients with MI aged ≤ 45 years were investigated. Risk factor control was assessed at the time of index MI and after 1 year. Major adverse cardiac and cerebrovascular events (MACCE) and its predictors were analyzed during long-term follow-up (median duration 49 months). RESULTS: A majority of patients with EOMI presented with insufficient risk factor control, even during 1-year follow-up. After 1-year 42% of patients were persistent smokers; 74% were physically inactive. The rate of obesity increased significantly from index MI (41%) to 1-year follow-up (46%, p = 0.03) as well as the rate of dysglycemia (index MI: 40%; 1-year follow-up: 51%, p < 0.01) and diabetes mellitus (index MI: 20%; 1-year follow-up: 24%, p < 0.01). 66% of the patients with diabetes mellitus had unsatisfactory HbA1c after 1 year; 69% of the patients did not attain guideline-recommended lipid targets. The rate of MACCE during long-term follow-up was 20% (incidence rate 0.05 per person-year). In a multivariable analysis smoking (HR 2.2, HR 1.3-3.7, p < 0.01) and physical inactivity (HR 2.8, HR 1.2-6.7, p = 0.02) were significant predictors for the occurrence of MACCE. CONCLUSION: Insufficient long-term risk factor control was common in patients with EOMI and was associated with an elevated rate of MACCE. The study reveals that better strategies for prevention in young patients are crucially needed.
RESUMEN
BACKGROUND: Left atrial appendage occlusion (LAAO) provides mechanical cardioembolic protection for atrial fibrillation (AF) patients who cannot use oral anticoagulation therapy (OAT). Patients with a thrombotic event despite OAT are at high risk for recurrence and may also benefit from LAAO. OBJECTIVES: This study sought to investigate the efficacy of LAAO in AF patients with a thrombotic event on OAT compared to: 1) LAAO in AF patients with a contraindication for OAT; and 2) historical data. METHODS: The international LAAO after stroke despite oral anticoagulation (STR-OAC LAAO) collaboration included patients who underwent LAAO because of thrombotic events on OAT. This cohort underwent propensity score matching and was compared to the EWOLUTION (Evaluating Real-Life Clinical Outcomes in Atrial Fibrillation Patients Receiving the WATCHMAN Left Atrial Appendage Closure Technology) registry, which represents patients who underwent LAAO because of OAT contraindications. The primary outcome was ischemic stroke. Event rates were compared between cohorts and with historical data without OAT, yielding relative risk reductions based on risk scores. RESULTS: Analysis of 438 matched pairs revealed no significant difference in the ischemic stroke rate between the STR-OAC LAAO and EWOLUTION cohorts (2.5% vs 1.9%; HR: 1.37; 95% CI: 0.72-2.61). STR-OAC LAAO patients exhibited a higher thromboembolic risk (HR: 1.71; 95% CI: 1.04-2.83) but lower bleeding risk (HR: 0.39; 95% CI: 0.18-0.88) compared to EWOLUTION patients. The mortality rate was slightly higher in EWOLUTION (4.3% vs 6.9%; log-rank P = 0.028). Relative risk reductions for ischemic stroke were 70% and 78% in STR-OAC LAAO and EWOLUTION, respectively, compared to historical data without OAT. CONCLUSIONS: LAAO in patients with a thrombotic event on OAT demonstrated comparable stroke rates to the OAT contraindicated population in EWOLUTION. The thromboembolic event rate was higher and the bleeding rate lower, reflecting the intrinsically different risk profile of both populations. Until randomized trials are available, LAAO may be considered in patients with an ischemic event on OAT.

BACKGROUND: The prognostic significance of various microvascular injury (MVI) patterns after ST-segment elevation myocardial infarction (STEMI) is not well known. OBJECTIVES: This study sought to investigate the prognostic implications of different MVI patterns in STEMI patients. METHODS: The authors analyzed 1,109 STEMI patients included in 3 prospective studies. Cardiac magnetic resonance (CMR) was performed 3 days (Q1-Q3: 2-5 days) after percutaneous coronary intervention (PCI) and included late gadolinium enhancement imaging for microvascular obstruction (MVO) and T2∗ mapping for intramyocardial hemorrhage (IMH). Patients were categorized into those without MVI (MVO-/IMH-), those with MVO but no IMH (MVO+/IMH-), and those with IMH (IMH+). RESULTS: MVI occurred in 633 (57%) patients, of whom 274 (25%) had an MVO+/IMH- pattern and 359 (32%) had an IMH+ pattern. Infarct size was larger and ejection fraction lower in IMH+ than in MVO+/IMH- and MVO-/IMH- (infarct size: 27% vs 19% vs 18% [P < 0.001]; ejection fraction: 45% vs 50% vs 54% [P < 0.001]). During a median follow-up of 12 months (Q1-Q3: 12-35 months), a clinical outcome event occurred more frequently in IMH+ than in MVO+/IMH- and MVO-/IMH- subgroups (19.5% vs 3.6% vs 4.4%; P < 0.001). IMH+ was the sole independent MVI parameter predicting major adverse cardiovascular events (HR: 3.88; 95% CI: 1.93-7.80; P < 0.001). CONCLUSIONS: MVI is associated with future adverse outcomes only in patients with a hemorrhagic phenotype (IMH+). Patients with only MVO (MVO+/IMH-) had a prognosis similar to patients without MVI (MVO-/IMH-). This highlights the independent prognostic importance of IMH in assessing and managing risk after STEMI.

BACKGROUND: Among low-risk patients with severe, symptomatic aortic stenosis who are eligible for both transcatheter aortic-valve implantation (TAVI) and surgical aortic-valve replacement (SAVR), data are lacking on the appropriate treatment strategy in routine clinical practice. METHODS: In this randomized noninferiority trial conducted at 38 sites in Germany, we assigned patients with severe aortic stenosis who were at low or intermediate surgical risk to undergo either TAVI or SAVR. Percutaneous- and surgical-valve prostheses were selected according to operator discretion. The primary outcome was a composite of death from any cause or fatal or nonfatal stroke at 1 year. RESULTS: A total of 1414 patients underwent randomization (701 to the TAVI group and 713 to the SAVR group). The mean (±SD) age of the patients was 74±4 years; 57% were men, and the median Society of Thoracic Surgeons risk score was 1.8% (low surgical risk). The Kaplan-Meier estimate of the primary outcome at 1 year was 5.4% in the TAVI group and 10.0% in the SAVR group (hazard ratio for death or stroke, 0.53; 95% confidence interval [CI], 0.35 to 0.79; P<0.001 for noninferiority). The incidence of death from any cause was 2.6% in the TAVI group and 6.2% in the SAVR group (hazard ratio, 0.43; 95% CI, 0.24 to 0.73); the incidence of stroke was 2.9% and 4.7%, respectively (hazard ratio, 0.61; 95% CI, 0.35 to 1.06). Procedural complications occurred in 1.5% and 1.0% of patients in the TAVI and SAVR groups, respectively. CONCLUSIONS: Among patients with severe aortic stenosis at low or intermediate surgical risk, TAVI was noninferior to SAVR with respect to death from any cause or stroke at 1 year.

BACKGROUND: Mitral transcatheter edge-to-edge repair (M-TEER) is a guideline-recommended treatment option for patients with severe symptomatic mitral regurgitation (MR). Outcomes with the PASCAL system in a post-market setting have not been established. OBJECTIVES: The authors report 30-day and 1-year outcomes from the MiCLASP (Transcatheter Repair of Mitral Regurgitation with Edwards PASCAL Transcatheter Valve Repair System) European post-market clinical follow-up study. METHODS: Patients with symptomatic, clinically significant MR were prospectively enrolled. The primary safety endpoint was clinical events committee-adjudicated 30-day composite major adverse event rate and the primary effectiveness endpoint was echocardiographic core laboratory-assessed MR severity at discharge compared with baseline. Clinical, echocardiographic, functional, and quality-of-life outcomes were assessed at 1 year. RESULTS: A total of 544 patients were enrolled (59% functional MR, 30% degenerative MR). The 30-day composite major adverse event rate was 6.8%. MR reduction was significant from baseline to discharge and sustained at 1 year with 98% of patients achieving MR ≤2+ and 82.6% MR ≤1+ (all P < 0.001 vs baseline). One-year Kaplan-Meier estimate for survival was 87.3%, and freedom from heart failure hospitalization was 84.3%. Significant functional and quality-of-life improvements were observed at 1 year, including 71.6% in NYHA functional class I/II, 14.4-point increase in Kansas City Cardiomyopathy Questionnaire score, and 24.2-m improvement in 6-minute walk distance (all P < 0.001 vs baseline). CONCLUSIONS: One-year outcomes of this large cohort from the MiCLASP study demonstrate continued safety and effectiveness of M-TEER with the PASCAL system in a post-market setting. Results demonstrate high survival and freedom from heart failure hospitalization, significant and sustained MR reduction, and improvements in symptoms, functional capacity, and quality of life.

This study aims at identifying risk-related patterns of left ventricular contraction dynamics via novel volume transient characterization. A multicenter cohort of AMI survivors (n = 1021) who underwent Cardiac Magnetic Resonance (CMR) after infarction was considered for the study. The clinical endpoint was the 12-month rate of major adverse cardiac events (MACE, n = 73), consisting of all-cause death, reinfarction, and new congestive heart failure. Cardiac function was characterized from CMR in 3 potential directions: by (1) volume temporal transients (i.e. contraction dynamics); (2) feature tracking strain analysis (i.e. bulk tissue peak contraction); and (3) 3D shape analysis (i.e. 3D contraction morphology). A fully automated pipeline was developed to extract conventional and novel artificial-intelligence-derived metrics of cardiac contraction, and their relationship with MACE was investigated. Any of the 3 proposed directions demonstrated its additional prognostic value on top of established CMR indexes, myocardial injury markers, basic characteristics, and cardiovascular risk factors (P < 0.001). The combination of these 3 directions of enhancement towards a final CMR risk model improved MACE prediction by 13% compared to clinical baseline (0.774 (0.771-0.777) vs. 0.683 (0.681-0.685) cross-validated AUC, P < 0.001). The study evidences the contribution of the novel contraction characterization, enabled by a fully automated pipeline, to post-infarction assessment.

BACKGROUND: Mortality after ST-segment elevation myocardial infarction (STEMI) is increased in patients with hypertension. The mechanisms underlying this association are uncertain. We sought to investigate whether patients with STEMI and prior hypertension have greater microvascular obstruction (MVO) and infarct size (IS) compared with those without hypertension. METHODS: We pooled individual patient data from 7 randomized trials of patients with STEMI undergoing primary percutaneous coronary intervention (PCI) in whom cardiac magnetic resonance imaging was performed within 1 month after reperfusion. The associations between hypertension and MVO, IS, and mortality were assessed in multivariable adjusted models. RESULTS: Among 2174 patients (61.3 ± 12.6 years, 76% male), 1196 (55.0%) had hypertension. Patients with hypertension were older, more frequently diabetic and had more extensive coronary artery disease than those without hypertension. MVO and IS measured as percent LV mass were not significantly different in patients with and without hypertension (adjusted differences 0.1, 95% CI -0.3 to 0.6, P = .61 and -0.2, 95% CI -1.5 to 1.2, P = .80, respectively). Hypertension was associated with a higher unadjusted risk of 1-year death (hazard ratio [HR] 2.28, 95% CI 1.44-3.60, P < .001), but was not independently associated with higher mortality after multivariable adjustment (adjusted HR 1.04, 95% CI 0.60-1.79, P = .90). CONCLUSION: In this large-scale individual patient data pooled analysis, hypertension was not associated with larger IS or MVO after primary PCI for STEMI.

BACKGROUND: Recently, abnormal thyroid function was shown to be common in patients with Takotsubo syndrome (TTS), being classified into "endocrine-type" and "stress-type" responses. The aim of this study was to investigate the association between thyroid homeostasis and TTS in a larger international registry. METHODS: In total 288 patients with TTS were enrolled through the GEIST multicentre registry from Germany, Italy and Spain. Thyrotropin (TSH), free T4 (FT4) and free T3 (FT3) concentrations were analysed at admission. Data were collected both retrospectively and prospectively from 2017 onwards. Primary endpoints included in-hospital and all-cause fatality, determined by cluster analysis using an unsupervised machine learning algorithm (k-medoids). FINDINGS: Three clusters were identified, classifying TTS with low (TSLT), high (TSHT) and normal (TSNT) thyroid output, based on TSH and FT4 levels in relation to the median thyroid's secretory capacity (SPINA-GT). Although TSH and FT4 concentrations were similar among survivors and non-survivors, these clusters were significantly associated with patient outcomes. In the longitudinal Kaplan-Meier analysis including in- and out-of-hospital survival, the prognosis related to concentrations of TSH, FT4, and FT3 as well as SPINA-GT, deiodinase activity (SPINA-GD) and clusters. Patients in the TSHT cluster and with cardiogenic shock had a lower initial left ventricular ejection fraction (LVEF). INTERPRETATION: This study suggests that thyroid hormones may impact the evolution and prognosis of TTS. The findings indicate that thyroid-derived biomarkers may help identify high-risk patients and pave the way for novel personalized and preventive therapeutic options. FUNDING: This research was not funded by any public, commercial, or not-for-profit agencies.

OBJECTIVES: The association of pulmonary hypertension (PH) with the outcome after mitral transcatheter edge-to-edge repair (M-TEER) focusing on the new ESC/ERS guidelines definition for PH. BACKGROUND: PH is frequently found in patients with mitral regurgitation and is associated with lower survival rates. Recent studies were based on echocardiographic parameters, but results based on invasive haemodynamics differentiating distinct types of PH using the new definition for PH are missing. METHODS: 449 consecutive M-TEER-treated patients from December 2009 to February 2015 were included in this retrospective analysis. All patients were stratified by the distinct types of PH (no PH, precapillary PH, isolated postcapillary PH, combined post-PH and precapillary PH) according to the definitions of the ESC/ERS guidelines for the diagnosis of PH from 2015 (meanPA cut-off <25 mm Hg, pulmonary capillary wedge pressure (PCWP) cut-off ≤15 mm Hg, diastolic pulmonary gradient cut-off ≥7 mm Hg or pulmonary vascular resistance (PVR) >3 WU) and 2022 (meanPA cut-off ≤20 mm Hg, PCWP cut-off ≤15 mm Hg, PVR cut-off ≥3 WU). RESULTS: Patients with any type of PH (2015: meanPA cut-off 25 mm Hg; 2022: meanPA cut-off >20 mm Hg) showed a higher risk of death after M-TEER compared with patients with no PH (2015: HR 1.61 (95% CI 1.25 to 2.07); p<0.001 and 2022: HR 2.09 (95% CI 1.54 to 2.83); p<0.001). Based on the new PH definition, each PH subgroup showed a lower survival after M-TEER compared with patients with no PH. Echocardiographic estimated systolic PAP showed a correlation with invasively measured mean pulmonary artery pressure (mPAP) (r=0.29, p<0.001) and systolic pulmonary arterial pressure (r=0.34,p<0.001). Cox-regression analysis showed higher invasive diastolic, systolic and mean pulmonary pressures were associated with higher all-cause mortality (p<0.001). In addition, invasive measured higher right atrial pressure, lower pulmonary arterial compliance, higher PVR and higher wedge pressure were identified as predictors of all-cause mortality after M-TEER. CONCLUSIONS: The new PH definition discriminates PH groups and mortality better than the old definition. The lower threshold of mPAP of 20mmHg improved prognostication in this cohort of patients.

BACKGROUND: Heart failure-related cardiogenic shock (HF-CS) accounts for a significant proportion of all CS cases. Nevertheless, there is a lack of evidence on sex-related differences in HF-CS, especially regarding use of treatment and mortality risk in women vs. men. This study aimed to investigate potential differences in clinical presentation, use of treatments, and mortality between women and men with HF-CS. METHODS: In this international observational study, patients with HF-CS (without acute myocardial infarction) from 16 tertiary-care centers in five countries were enrolled between 2010 and 2021. Logistic and Cox regression models were used to assess differences in clinical presentation, use of treatments, and 30-day mortality in women vs. men with HF-CS. RESULTS: N = 1030 patients with HF-CS were analyzed, of whom 290 (28.2%) were women. Compared to men, women were more likely to be older, less likely to have a known history of heart failure or cardiovascular risk factors, and lower rates of highly depressed left ventricular ejection fraction and renal dysfunction. Nevertheless, CS severity as well as use of treatments were comparable, and female sex was not independently associated with 30-day mortality (53.0% vs. 50.8%; adjusted HR 0.94, 95% CI 0.75-1.19). CONCLUSIONS: In this large HF-CS registry, sex disparities in risk factors and clinical presentation were observed. Despite these differences, the use of treatments was comparable, and both sexes exhibited similarly high mortality rates. Further research is necessary to evaluate if sex-tailored treatment, accounting for the differences in cardiovascular risk factors and clinical presentation, might improve outcomes in HF-CS.

BACKGROUND: The role of age in the short- and long-term prognosis of takotsubo syndrome (TTS) is controversial. The aim of the present study was to evaluate age-related differences and prognostic implications among patients with TTS. METHODS AND RESULTS: In total, 2492 consecutive patients with TTS enrolled in an international registry were stratified into 4 groups (<45, 45-64, 65-74, and ≥75 years). The median long-term follow-up was 480 days (interquartile range, 83-1510 days). The primary outcome was all-cause mortality (in-hospital and out-of-hospital mortality). The secondary end point was TTS-related in-hospital complications. Among the 2479 patients, 58 (2.3%) were aged <45 years, 625 (25.1%) were aged 45 to 64 years, 733 (29.4%) were aged 65 to 74 years, and 1063 (42.6%) were aged ≥75 years. Young patients (<45 years) had a higher prevalence of men (from youngest to oldest, 24.1% versus 12.6% versus 9.7% versus 11.4%; P<0.01), physical triggers (46.6% versus 27.5%, 33.9%, and 38.4%; P<0.01), and non-apical forms of TTS (25.9% versus 23.7%, 12.7%, and 9%; P<0.01) than those aged 45 to 64, 65 to 74, and ≥75 years. During hospitalization, young patients experienced a higher rate of in-hospital complications (32.8% versus 23.4%, 27.4%, and 31.9%; P=0.01), but in-hospital mortality was higher in the older group (0%, 1.6%, 2.9%, and 5%; P=0.001). Long-term all-cause mortality was significantly higher in the older cohort (5.6%, 6.4%, 11.3%, and 22.3%; log-rank P<0.001), as was long-term cardiovascular mortality (0%, 0.9%, 1.9%, and 3.2%; log-rank P=0.01). CONCLUSIONS: Young patients with TTS have a typical phenotype characterized by a higher prevalence of male sex, non-apical ballooning patterns, and in-hospital complications. However, in-hospital and long-term mortality are significantly lower in young patients with TTS. REGISTRATION: URL: https://classic.clinicaltrials.gov/ct2/show/NCT04361994.

BACKGROUND: Neurological disorders as a risk factor for Takotsubo syndrome (TTS) are not well characterized. The aim of the study was to evaluate TTS-associated neurological phenotypes and outcome. METHODS AND RESULTS: Patients with TTS enrolled in the international multicenter GEIST (German Italian Spanish Takotsubo) registry were analyzed. Prevalence, clinical characteristics, and short- and long-term outcomes of patients with TTS were recorded. A subgroup analysis of the 5 most represented neurological disorders was performed. In total, 400 (17%) of 2301 patients had neurological disorders. The most represented neurological conditions were previous cerebrovascular events (39%), followed by neurodegenerative disorders (30.7%), migraine (10%), epilepsy (9.5%), and brain tumors (5%). During hospitalization, patients with neurological disorders had longer in-hospital stay (8 [interquartile range, 5-12] versus 6 [interquartile range, 5-9] days; P<0.01) and more often experienced in-hospital complications (27% versus 16%; P=0.01) mainly driven by cardiogenic shock and in-hospital death (12% versus 7.6% and 6.5% versus 2.8%, respectively; both P<0.01). Survival analysis showed a higher mortality rate in neurological patients both at 60 days and long-term (8.8% versus 3.4% and 23.5% versus 10.1%, respectively; both P<0.01). Neurological disorder was an independent predictor of both the 60-day and long-term mortality rate (odds ratio, 1.78 [95% CI, 1.07-2.97]; P=0.02; hazard ratio, 1.72 [95% CI, 1.33-2.22]; both P<0.001). Patients with neurodegenerative disorders had the worst prognosis among the neurological disease subgroups, whereas patients with TTS with migraine had a favorable prognosis (long-term mortality rates, 29.2% and 9.7%, respectively). CONCLUSIONS: Neurological disorders identify a high-risk TTS subgroup for enhanced short- and long-term mortality rate. Careful recognition of neurological disorders and phenotype is therefore needed.

BACKGROUND: Glucagon-like peptide-1 (GLP-1) is a gut-derived peptide secreted in response to nutritional and inflammatory stimuli. Elevated GLP-1 levels predict adverse outcome in patients with acute myocardial infarction or sepsis. GLP-1 holds cardioprotective effects and GLP-1 receptor agonists reduce cardiovascular events in high-risk patients with diabetes. In this study, we aimed to investigate the capacity of GLP-1 to predict outcome in patients with cardiogenic shock (CS) complicating myocardial infarction. METHODS: Circulating GLP-1 levels were serially assessed in 172 individuals during index PCI and day 2 in a prospectively planned biomarker substudy of the IABP-SHOCK II trial. All-cause mortality at short- (30 days), intermediate- (1 year), and long-term (6 years) follow-up was used for outcome assessment. RESULTS: Patients with fatal short-term outcome (n = 70) exhibited higher GLP-1 levels [86 (interquartile range 45-130) pM] at ICU admission in comparison to patients with 30-day survival [48 (interquartile range 33-78) pM; p < 0.001] (n = 102). Repeated measures ANOVA revealed a significant interaction of GLP-1 dynamics from baseline to day 2 between survivors and non-survivors (p = 0.04). GLP-1 levels above vs. below the median proved to be predictive for short- [hazard ratio (HR) 2.43; 95% confidence interval (CI) 1.50-3.94; p < 0.001], intermediate- [HR 2.46; 95% CI 1.62-3.76; p < 0.001] and long-term [HR 2.12; 95% CI 1.44-3.11; p < 0.001] outcome by multivariate Cox-regression analysis. CONCLUSION: Elevated plasma levels of GLP-1 are an independent predictor for impaired prognosis in patients with myocardial infarction complicated by CS. The functional relevance of GLP-1 in this context is currently unknown and needs further investigations. TRIAL REGISTRATION: www. CLINICALTRIALS: gov Identifier: NCT00491036.

AIMS: Heart failure-related cardiogenic shock (HF-CS) accounts for a significant proportion of CS cases. Whether patients with de novo HF and those with acute-on-chronic HF in CS differ in clinical characteristics and outcome remains unclear. The aim of this study was to evaluate differences in clinical presentation and mortality between patients with de novo and acute-on-chronic HF-CS. METHODS AND RESULTS: In this international observational study, patients with HF-CS from 16 tertiary care centres in five countries were enrolled between 2010 and 2021. To investigate differences in clinical presentation and 30-day mortality, adjusted logistic/Cox regression models were fitted. Patients (n = 1030) with HF-CS were analysed, of whom 486 (47.2%) presented with de novo HF-CS and 544 (52.8%) with acute-on-chronic HF-CS. Traditional markers of CS severity (e.g. blood pressure, heart rate and lactate) as well as use of treatments were comparable between groups. However, patients with acute-on-chronic HF-CS were more likely to have a higher CS severity and also a higher mortality risk, after adjusting for relevant confounders (de novo HF 45.5%, acute-on-chronic HF 55.9%, adjusted hazard ratio 1.38, 95% confidence interval 1.10-1.72, p = 0.005). CONCLUSION: In this large HF-CS cohort, acute-on-chronic HF-CS was associated with more severe CS and higher mortality risk compared to de novo HF-CS, although traditional markers of CS severity and use of treatments were comparable. These findings highlight the vast heterogeneity of patients with HF-CS, emphasize that HF chronicity is a relevant disease modifier in CS, and indicate that future clinical trials should account for this.

INTRODUCTION: Takotsubo syndrome (TTS) is an acute heart failure syndrome, featured by transient left ventricular systolic dysfunction. Recurrences of TTS are not infrequent and there is no standard preventive therapy. The aim of this study was to evaluate in a network meta-analysis if beta-blockers (BB) and ACE inhibitors/angiotensin receptor blockers (ACEi/ARBs), in combination or not, can effectively prevent TTS recurrences. METHODS: We performed a systematic network meta-analysis, using MEDLINE/EMBASE and the Cochrane Central Register of Controlled Trials for clinical studies published between January 2010 and September 2022. We considered all those studies including patients receiving medical therapy with BB, ACEi/ARBs. The primary outcome was TTS recurrence. RESULTS: We identified 6 clinical studies encompassing a total of 3407 patients with TTS. At 40±10 months follow-up, TTS recurrence was reported in 160 (4.7%) out of 3407 patients. Mean age was 69.8±2 years and 394 patients (11.5%) out of 3407 were male. There were no differences in terms of TTS recurrence when comparing ACEi/ARBs versus control (OR 0.83; 95% CI 0.47 to 1.47, p=0.52); BB versus control (OR 1.01; 95% CI 0.63 to 1.61, p=0.96) and ACEi/ARBs versus BB (OR 0.88; 95% CI 0.51 to 1.53, p=0.65).Combination of BB and ACEi/ARBs was also not effective in reducing the risk of recurrence versus control (OR 0.91; 95% CI 0.58 to 1.43, p=0.68) vs ACEi/ARBs (OR 0.79; 95% CI 0.46 to 1.34, p=0.38)) and vs BB (OR 0.77; 95% CI 0.49 to 1.21, p=0.26). CONCLUSIONS: Our study did not find sufficient statistical evidence regarding combination therapy with BB and ACEi/ARBs in reduction of TTS recurrence.
