RESUMEN
BACKGROUND: Young patients suffering from cryptogenic stroke alongside a patent foramen ovale (PFO) are often considered for percutaneous device closure to reduce the risk of stroke recurrence. Residual right-to-left shunt after device closure may persist in approximately a quarter of the patients at 6 months, and some may close at a later time point. This study aimed to assess the prevalence and persistence of residual right-to-left shunt after percutaneous PFO closure. METHODS: Consecutive patients undergoing transoesophageal echocardiography-guided PFO closure for cryptogenic stroke between 2006 and 2021, with echocardiographic follow-up including contrast bubble study and Valsalva manoeuvre, were enrolled. Follow-up transthoracic echocardiography was performed at 6 months and repeated at 12 months in case of residual right-to-left shunt. Primary outcomes included the prevalence and grade of residual right-to-left shunt at 6 and 12 months after percutaneous PFO closure. RESULTS: 227 patients were included with a mean age of 43±11 years and 50.2% were women. At 6-month follow-up, 72.7% had no residual right-to-left shunt, 12.3% small residual right-to-left shunt, 6.6% moderate residual right-to-left shunt and 8.4% large residual right-to-left shunt. At 12-month follow-up, the presence of residual right-to-left shunt in all patients was 12.3%, of whom 6.6% had small residual right-to-left shunt, 2.6% had moderate residual right-to-left shunt and 3.1% had large residual right-to-left shunt. CONCLUSIONS: Residual right-to-left shunts are common at 6 months after percutaneous closure of PFO. However, the majority are small and two-thirds of residual right-to-left shunts achieve complete closure between 6 and 12 months.
RESUMEN
BACKGROUND AND AIMS: A routine invasive strategy is recommended in the management of higher risk patients with non-ST-elevation acute coronary syndromes (NSTE-ACSs). However, patients with previous coronary artery bypass graft (CABG) surgery were excluded from key trials that informed these guidelines. Thus, the benefit of a routine invasive strategy is less certain in this specific subgroup. METHODS: A systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted. A comprehensive search was performed of PubMed, EMBASE, Cochrane, and ClinicalTrials.gov. Eligible studies were RCTs of routine invasive vs. a conservative or selective invasive strategy in patients presenting with NSTE-ACS that included patients with previous CABG. Summary data were collected from the authors of each trial if not previously published. Outcomes assessed were all-cause mortality, cardiac mortality, myocardial infarction, and cardiac-related hospitalization. Using a random-effects model, risk ratios (RRs) with 95% confidence intervals (CIs) were calculated. RESULTS: Summary data were obtained from 11 RCTs, including previously unpublished subgroup outcomes of nine trials, comprising 897 patients with previous CABG (477 routine invasive, 420 conservative/selective invasive) followed up for a weighted mean of 2.0 (range 0.5-10) years. A routine invasive strategy did not reduce all-cause mortality (RR 1.12, 95% CI 0.97-1.29), cardiac mortality (RR 1.05, 95% CI 0.70-1.58), myocardial infarction (RR 0.90, 95% CI 0.65-1.23), or cardiac-related hospitalization (RR 1.05, 95% CI 0.78-1.40). CONCLUSIONS: This is the first meta-analysis assessing the effect of a routine invasive strategy in patients with prior CABG who present with NSTE-ACS. The results confirm the under-representation of this patient group in RCTs of invasive management in NSTE-ACS and suggest that there is no benefit to a routine invasive strategy compared to a conservative approach with regard to major adverse cardiac events. These findings should be validated in an adequately powered RCT.

BACKGROUND: Multisystem inflammatory syndrome in children is an inflammatory syndrome related to severe acute respiratory syndrome coronavirus 2 with a high risk of cardiovascular complications (vasoplegia, cardiac shock). We investigated the cardiac outcomes in multisystem inflammatory syndrome in children, focusing on the identification of predictors for late cardiac function impairment. METHODS: Clinical characteristics, conventional echocardiography (left ventricle ejection fraction, fractional shortening), 4-chamber left ventricular global longitudinal strain, and cardiac MRI of multisystem inflammatory syndrome in children patients (n = 48) were collected during admission, 6 weeks, 6 months, >12-≤18 months, and >18-≤24 months post-onset. Paired over-time patterns were assessed and multivariable regression analyses were performed to identify predictors for late global longitudinal strain impairment. RESULTS: In total, 81.3% of patients had acute cardiac dysfunction (left ventricle ejection fraction <50% and/or fractional shortening <28%). The left ventricle ejection fraction and fractional shortening reached a plateau level ≤6 weeks, while the global longitudinal strain continued to decrease in the first 6 months post-onset (median -17.3%, P < 0.001 [versus acute]). At 6 months, 35.7% of the patients still had an abnormal global longitudinal strain, which persisted in 5/9 patients that underwent echocardiography >12-≤18 months post-onset and in 3/3 patients >18-≤24 months post-onset. In a multivariable analysis, soluble troponin T (>62.0 ng/L [median]) was associated with reduced global longitudinal strain at 6 months. Our cardiac MRI findings indicated acute myocardial involvement (increased T1/T2 value) in 77.8% (7/9), which recovered quickly without signs of fibrosis on convalescent cardiac MRIs. CONCLUSIONS: Late global longitudinal strain impairment is seen in some multisystem inflammatory syndrome in children patients up to one-year post-onset. Careful cardiac follow-up in patients with elevated troponin in the acute phase and patients with persistent abnormal global longitudinal strain is warranted until resolution of the global longitudinal strain since the long-term implications of such abnormalities are still unclear.
RESUMEN
Background: The Apple Watch has the capability to record a lead 1 electrocardiogram (ECG) and can identify and report atrial fibrillation. The use for detecting myocardial ischaemia is not endorsed by Apple but is documented in this case. Case summary: A 76-year-old man made a lead 1 ECG with his Apple Watch immediately after exercising on a cross trainer. He was fully asymptomatic. The ECG showed an unusual negative T-wave in this lead 1 that deepened in a few minutes and returned to normal after 22â min. He consulted a cardiologist and a standard exercise ECG confirmed the negative T-wave in lead 1 after maximal exercise and in addition showed widespread ST-depression indicating myocardial ischaemia, again without any clinical symptoms. Further studies revealed severe obstructive three-vessel coronary artery disease that was considered not suitable for percutaneous intervention. A coronary artery bypass operation on all involved vessels was performed successfully. Recovery was uneventful and an exercise ECG repeated 11 weeks later was normal. Discussion: We demonstrated that the lead 1 ECG made with the Apple Watch can reliably record T-wave changes indicating myocardial ischaemia. The use of the Apple Watch to document ischaemic changes should be studied systematically for its potential to identify myocardial ischaemia, mainly triggered by symptoms but maybe for asymptomatic persons as well.
RESUMEN
BACKGROUND: We aimed to identify patients with subphenotypes of postacute coronary syndrome (ACS) using repeated measurements of high-sensitivity cardiac troponin T, N-terminal pro-B-type natriuretic peptide, high-sensitivity C-reactive protein, and growth differentiation factor 15 in the year after the index admission, and to investigate their association with long-term mortality risk. METHODS AND RESULTS: BIOMArCS (BIOMarker Study to Identify the Acute Risk of a Coronary Syndrome) was an observational study of patients with ACS, who underwent high-frequency blood sampling for 1 year. Biomarkers were measured in a median of 16 repeated samples per individual. Cluster analysis was performed to identify biomarker-based subphenotypes in 723 patients without a repeat ACS in the first year. Patients with a repeat ACS (N=36) were considered a separate cluster. Differences in all-cause death were evaluated using accelerated failure time models (median follow-up, 9.1 years; 141 deaths). Three biomarker-based clusters were identified: cluster 1 showed low and stable biomarker concentrations, cluster 2 had elevated concentrations that subsequently decreased, and cluster 3 showed persistently elevated concentrations. The temporal biomarker patterns of patients in cluster 3 were similar to those with a repeat ACS during the first year. Clusters 1 and 2 had a similar and favorable long-term mortality risk. Cluster 3 had the highest mortality risk. The adjusted survival time ratio was 0.64 (95% CI, 0.44-0.93; P=0.018) compared with cluster 1, and 0.71 (95% CI, 0.39-1.32; P=0.281) compared with patients with a repeat ACS. CONCLUSIONS: Patients with subphenotypes of post-ACS with different all-cause mortality risks during long-term follow-up can be identified on the basis of repeatedly measured cardiovascular biomarkers. Patients with persistently elevated biomarkers have the worst outcomes, regardless of whether they experienced a repeat ACS in the first year.

BACKGROUND: International guidelines for the management of valvular heart disease recommend frailty assessment prior to Transcatheter Aortic Valve Implantation (TAVI), however there is no consensus how to assess frailty. We investigated whether frailty status assessed with the Edmonton Frail Scale (EFS, range 0-17 points) relates to length of stay (LOS), short- and long-term mortality and adverse outcomes after TAVI. METHODS: In this study we included 357 patients between April 2016 till December 2018. EFS was assessed at baseline. Patients were classified into low (0-3), intermediate (4-7) or high frailty status (8-17). LOS was defined as the number of days between admission and discharge. Mortality data were obtained up to four years after TAVI. Adverse events were defined by Valve Academic Research Consortium (VARC)-2 criteria and collected <30 days after TAVI. RESULTS: Patients with higher frailty status had longer median LOS (days (IQR): low 5 (3), intermediate 6 (4) and high 7 (5), p < 0.001) and higher mortality: low vs intermediate vs high at 30 days 0.5%, 2.2%, 7.0% (p = 0.050), 1 year 3.7%, 10.0%, 15.2% (p = 0.052), 2 years 9.2%, 17.8%, 31.7% (p = 0.003), 3 years 17.2%, 24.0, 47.0% (p = 0.001) and 4 years 19.6%, 30.8%, 55.6% (p < 0.001). Frail patients received more often a pacemaker (2.6%, 6.6%, 13.5%, p = 0.048). CONCLUSION: In clinical practice, the EFS is a useful tool to screen for frailty in TAVI patients. This tool may possibly be expanded to determine benefit versus harm-risk in these patients and whether specific pre-procedurally interventions are needed in order to reduce mortality.

INTRODUCTION: Acute mechanical thrombectomy (MT) is the preferred treatment for large vessel occlusion-related stroke. Histopathological research on the obtained occlusive embolic thrombus may provide information regarding the aetiology and pathology of the lesion to predict prognosis and propose possible future acute ischaemic stroke therapy. METHODS: A total of 75 consecutive patients who presented to the Amphia Hospital with acute large vessel occlusion-related stroke and underwent MT were included in the study. The obtained thrombus materials were subjected to standard histopathological examination. Based on histological criteria, they were considered fresh (<1 day old) or old (>1 day old). Patients were followed for 2 years for documentation of all-cause mortality. RESULTS: Thrombi were classified as fresh in 40 patients (53%) and as older in 35 patients (47%). Univariate Cox regression analysis showed that thrombus age, National Institutes of Health Stroke Scale at hospital admission, and patient age were associated with long-term mortality (p < 0.1). Multivariable Cox hazards and Kaplan-Meier analysis demonstrated that after extensive adjustment for clinical and procedural variables, thrombus age persisted in being independently associated with higher long-term mortality (hazard ratio: 3.34; p = 0.038, log-rank p = 0.013). CONCLUSION: In this study, older thromboemboli are responsible for almost half of acute large ischaemic strokes. Moreover, the presence of an old thrombus is an independent predictor of mortality in acute large vessel occlusion-related stroke. More research is warranted regarding future therapies based on thrombus composition.

Background: Treatment of patients diagnosed with angina due to epicardial or microvascular coronary artery spasm (CAS) is challenging because patients often remain symptomatic despite conventional pharmacological therapy. In this prospective, randomized, double-blind, placebo-controlled, sequential cross-over proof-of-concept study, we compared the efficacy and safety of macitentan, a potent inhibitor of the endothelin-1 receptor, to placebo in symptomatic patients with CAS despite background pharmacological treatment. Methods: Patients with CAS diagnosed by invasive spasm provocation testing with >3 anginal attacks per week despite pharmacological treatment were considered for participation. Participants received either 10 mg of macitentan or placebo daily for 28 days as add-on treatment. After a wash-out period patients were crossed over to the alternate treatment arm. The primary endpoint was the difference in anginal burden calculated as [1] the duration (in minutes) * severity (on a Visual Analogue Scale (VAS) pain scale 1-10); and [2] the frequency of angina attacks * severity during medication use compared to the run-in phase. Results: 28 patients of whom 22 females (79%) and a mean age of 55.3 ± 7.6 completed the entire study protocol (epicardial CAS n = 19 (68), microvascular CAS n = 9 (32)). Change in both indices of anginal burden were not different during treatment with add-on macitentan as compared to add-on placebo (duration*severity: -9 [-134 78] vs -45 [-353 11], p = 0.136 and frequency*severity: -1.7 [-5.8 1.2] vs -1.8 [-6.2 0.3], p = 0.767). The occurrence and nature of self-reported adverse events were closely similar between the treatment phase with macitentan and placebo. Conclusion: In patients with angina due to epicardial or microvascular CAS despite background pharmacological treatment, 28 days of add-on treatment with the ET-1 receptor antagonist, macitentan 10 mg daily, did not reduce anginal burden compared to add-on treatment with placebo.Trial Registrationhttps://trialsearch.who.int/, Identifier: EUCTR2018-002623-42-NL.

RESUMEN
Paravalvular leak (PVL) is a shortcoming that can erode the clinical benefits of transcatheter valve replacement (TAVR) and therefore a readily applicable method (aortography) to quantitate PVL objectively and accurately in the interventional suite is appealing to all operators. The ratio between the areas of the time-density curves in the aorta and left ventricular outflow tract (LVOT-AR) defines the regurgitation fraction (RF). This technique has been validated in a mock circulation; a single injection in diastole was further tested in porcine and ovine models. In the clinical setting, LVOT-AR was compared with trans-thoracic and trans-oesophageal echocardiography and cardiac magnetic resonance imaging. LVOT-AR > 17% discriminates mild from moderate aortic regurgitation on echocardiography and confers a poor prognosis in multiple registries, and justifies balloon post-dilatation. The LVOT-AR differentiates the individual performances of many old and novel devices and is being used in ongoing randomized trials and registries.
RESUMEN
INTRODUCTION: Increasing survival of adult congenital heart disease (ACHD) patients comes at the price of a range of late complications-arrhythmias, heart failure, and valvular dysfunction. Transcatheter valve interventions have become a legitimate alternative to conventional surgical treatment in selected acquired heart disease patients. However, literature on technical aspects, hemodynamic effects, and clinical outcomes of percutaneous atrioventricular (AV) valve interventions in ACHD patients is scarce. METHOD: This is a descriptive cohort from CAHAL (Center of Congenital Heart Disease Amsterdam-Leiden). ACHD patients with severe AV valve regurgitation who underwent a transcatheter intervention in the period 2020-2022 were included. Demographic, clinical, procedural, and follow-up data were collected from patient records. RESULTS: Five ACHD patients with severe or torrential AV valve regurgitation are described. Two patients underwent a transcatheter edge-to-edge repair (TEER), one patient underwent a valve-in-valve procedure, one patient received a Cardioband system, and one patient received both a Cardioband system and TEER. No periprocedural complications occurred. Post-procedural AV valve regurgitation as well as NYHA functional class improved in all patients. The median post-procedural NYHA functional class improved from 3.0 (IQR [2.5-4.0]) to 2.0 (IQR [1.5-2.5]). One patient died 9 months after the procedure due to advanced heart failure with multiorgan dysfunction. CONCLUSION: Transcatheter valve repair is feasible and safe in selected complex ACHD patients. A dedicated heart team is essential for determining an individualized treatment strategy as well as pre- and periprocedural imaging to address the underlying mechanism(s) of AV regurgitation and guide the transcatheter intervention. Long-term follow-up is essential to evaluate the clinical outcomes of transcatheter AV valve repair in ACHD patients.
RESUMEN
Background: Intracoronary acetylcholine (ACh) provocation is an established method for diagnosing epicardial and microvascular vasospasm in contemporary clinical practice. We hypothesize that ACh-induced vasospasm is followed by post-spastic reactive hyperemia (PSRH), which is measured as an increased flow-recovery time. Objectives: To assess flow-recovery time, indicative of ischemia, among the diagnostic endotypes that follow ACh provocation testing. Methods: Patients with angina and non-obstructive coronary artery disease on angiography who underwent ACh provocation testing were included in this analysis. Doppler flow was continuously measured during the procedure and used to determine the flow-recovery time, which was calculated as time between cessation of ACh infusion and the point of flow recovery. Results: Conventional provocation testing according to the COVADIS criteria diagnosed vasospasm in 63%(77/123), an equivocal result in 22%(27/123) and a negative result in 15%(19/123) of patients. In reaction to the highest-dose of ACh, flow-recovery time was significantly extended and similar in the epicardial, microvascular and equivocal test results compared to the negative result (all p < 0.001) indicative of PSRH. Conclusion: Flow-recovery time in patients with an equivocal result is similar to patients with vasospasm, which indicates the occurrence of myocardial ischemia and therefore, these patients may benefit from medical treatment.
RESUMEN
Migraine is a chronic neurovascular disease with a complex, not fully understood pathophysiology with multiple causes. People with migraine suffer from recurrent moderate to severe headache attacks varying from 4 to 72 h. The prevalence of migraine is two to three times higher in women compared with men. Importantly, it is the most disabling disease in women <50 years of age due to a high number of years lived with disability, resulting in a very high global socioeconomic burden. Robust evidence exists on the association between migraine with aura and increased incidence of cardiovascular disease (CVD), in particular ischaemic stroke. People with migraine with aura have an increased risk of atrial fibrillation, myocardial infarction, and cardiovascular death compared with those without migraine. Ongoing studies investigate the relation between migraine and angina with non-obstructive coronary arteries and migraine patients with patent foramen ovale. Medication for the treatment of migraine can be preventative medication, such as beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, antiepileptics, antidepressants, some of the long-acting calcitonin gene-related peptide receptor antagonists, or monoclonal antibodies against calcitonin gene-related peptide or its receptor, or acute medication, such as triptans and calcitonin gene-related peptide receptor antagonists. However, these medications might raise concerns when migraine patients also have CVD due to possible (coronary) side effects. Specifically, knowledge gaps remain for the contraindication to newer treatments for migraine. All cardiologists will encounter patients with CVD and migraine. This state-of-the-art review will outline the basic pathophysiology of migraine and the associations between migraine and CVD, discuss current therapies, and propose future directions for research.

Renal sympathetic innervation is important in the control of renal and systemic hemodynamics and is a target for pharmacological and catheter-based therapies. The effect of a physiological sympathetic stimulus using static handgrip exercise on renal hemodynamics and intraglomerular pressure in humans is unknown. We recorded renal arterial pressure and flow velocity in patients with a clinical indication for coronary or peripheral angiography using a sensor-equipped guidewire during baseline, handgrip, rest, and hyperemia following intrarenal dopamine (30 µg/kg). Changes in perfusion pressure were expressed as the change in mean arterial pressure, and changes in flow were expressed as a percentage with respect to baseline. Intraglomerular pressure was estimated using a Windkessel model. A total of 18 patients (61% male and 39% female) with a median age of 57 yr (range: 27-85 yr) with successful measurements were included. During static handgrip, renal arterial pressure increased by 15.2 mmHg (range: 4.2-53.0 mmHg), whereas flow decreased by 11.2%, but with a large variation between individuals (range: -13.4 to 49.8). Intraglomerular pressure increased by 4.2 mmHg (range: -3.9 to 22.1 mmHg). Flow velocity under resting conditions remained stable, with a median of 100.6% (range: 82.3%-114.6%) compared with baseline. During hyperemia, maximal flow was 180% (range: 111%-281%), whereas intraglomerular pressure decreased by 9.6 mmHg (interquartile range: 4.8 to 13.9 mmHg). Changes in renal pressure and flow during handgrip exercise were significantly correlated (ρ = -0.68, P = 0.002). Measurement of renal arterial pressure and flow velocity during handgrip exercise allows the identification of patients with higher and lower sympathetic control of renal perfusion. This suggests that hemodynamic measurements may be useful to assess the response to therapeutic interventions aimed at altering renal sympathetic control.NEW & NOTEWORTHY Renal sympathetic innervation is important in the homeostasis of systemic and renal hemodynamics. We showed that renal arterial pressure significantly increased and that flow decreased during static handgrip exercise using direct renal arterial pressure and flow measurements in humans, but with a large difference between individuals. These findings may be useful for future studies aimed to assess the effect of interventions that influence renal sympathetic control.

BACKGROUND: NobleStitch EL is a novel suture-based technique used for patent foramen ovale (PFO) closure and an alternative to traditional double-disc devices without the need for antithrombotic therapy. However, successful closure rates are still unknown, and certain anatomies may be unfavorable for successful closure. AIMS: We assessed the efficacy of the NobleStitch EL and sought to identify patient-related anatomical features associated with successful suture-based closure. METHODS: We included 55 patients who underwent PFO closure with the NobleStitch EL in The Netherlands and Switzerland. Successful closure was defined as residual right-to-left shunt grade ≤1 with Valsalva maneuver at a cardiac ultrasound. Predefined possible anatomical determinants for effective closure included PFO length, atrial septal aneurysm, PFO entry- and exit diameter. RESULTS: Successful closure was achieved in 33 patients (60%). The PFO length was shorter in patients with successful closure compared to unsuccessful closure with a median length of 9.6 mm (IQR 8.0-15.0) versus 13.3 mm (IQR 11.4-18.6) on preprocedural ultrasound (p = 0.041) and 9.9 mm (IQR 8.0-13.1) versus 12.5 mm (IQR 9.7-15.4) on angiography (p = 0.049). Additionally, the PFO exit diameter and PFO volume were smaller in patients with successful closure than unsuccessful closure, with a mean diameter of 7.0 ± 3.1 mm versus 9.5 ± 3.8 mm (p = 0.015) and a median volume of 381 mm3 (IQR 286-894) versus 985 mm3 (IQR 572-1550) (p = 0.016). CONCLUSION: In our study cohort, the successful PFO closure rate using NobleStitch EL was relatively low (60%). With this alternative procedure, patients with a small PFO driven by a short PFO tunnel length and small exit diameter seem to be eligible for successful suture-based closure.

OBJECTIVES: This study sought to present an angiography-based computational model for serial assessment of superficial wall strain (SWS, dimensionless) of de-novo coronary stenoses treated with either bioresorbable scaffold (BRS) or drug-eluting stent (DES). BACKGROUND: A novel method for SWS allows the assessment of the mechanical status of arteries in-vivo, which may help for predicting cardiovascular outcomes. METHODS: Patients with arterial stenosis treated with BRS (n = 21) or DES (n = 21) were included from ABSORB Cohort B1 and AIDA trials. The SWS analyses were performed along with quantitative coronary angiography (QCA) at pre-PCI, post-PCI, and 5-year follow-up. Measurements of QCA and SWS parameters were quantified at the treated segment and adjacent 5-mm proximal and distal edges. RESULTS: Before PCI, the peak SWS on the 'to be treated' segment (0.79 ± 0.36) was significantly higher than at both virtual edges (0.44 ± 0.14 and 0.45 ± 0.21; both p < 0.001). The peak SWS in the treated segment significantly decreased by 0.44 ± 0.13 (p < 0.001). The surface area of high SWS decreased from 69.97mm2 to 40.08mm2 (p = 0.002). The peak SWS in BRS group decreased to a similar extent (p = 0.775) from 0.81 ± 0.36 to 0.41 ± 0.14 (p < 0.001), compared with DES group from 0.77 ± 0.39 to 0.47 ± 0.13 (p = 0.001). Relocation of high SWS to device edges was often observed in both groups after PCI (35 of 82 cases, 41.7 %). At follow-up of BRS, the peak SWS remained unchanged compared to post-PCI (0.40 ± 0.12 versus 0.36 ± 0.09, p = 0.319). CONCLUSION: Angiography-based SWS provided valuable information about the mechanical status of coronary arteries. Device implantation led to a significant decrease of SWS to a similar extent with either polymer-based scaffolds or permanent metallic stents.

AIMS: Evidence regarding the role of serial measurements of biomarkers for risk assessment in post-acute coronary syndrome (ACS) patients is limited. The aim was to explore the prognostic value of four, serially measured biomarkers in a large, real-world cohort of post-ACS patients. METHODS AND RESULTS: BIOMArCS is a prospective, multi-centre, observational study in 844 post-ACS patients in whom 12 218 blood samples (median 17 per patient) were obtained during 1-year follow-up. The longitudinal patterns of high-sensitivity cardiac troponin T (hs-cTnT), N-terminal-pro-B-type natriuretic peptide (NT-proBNP), high-sensitivity C-reactive protein (hs-CRP), and growth differentiation factor 15 (GDF-15) were analysed in relation to the primary endpoint (PE) of cardiovascular mortality and recurrent ACS using multivariable joint models. Median age was 63 years, 78% were men and the PE was reached by 45 patients. The average biomarker levels were systematically higher in PE compared with PE-free patients. After adjustment for 6-month post-discharge Global Registry of Acute Coronary Events score, 1 standard deviation increase in log[hs-cTnT] was associated with a 61% increased risk of the PE [hazard ratio (HR) 1.61, 95% confidence interval (CI) 1.02-2.44, P = 0.045], while for log[GDF-15] this was 81% (HR 1.81, 95% CI 1.28-2.70, P = 0.001). These associations remained significant after multivariable adjustment, while NT-proBNP and hs-CRP were not. Furthermore, GDF-15 level showed an increasing trend prior to the PE (Structured Graphical Abstract). CONCLUSION: Longitudinally measured hs-cTnT and GDF-15 concentrations provide prognostic value in the risk assessment of clinically stabilized patients post-ACS.

OBJECTIVES: The current study sought to determine whether low-dose dobutamine stress echocardiography (DSE) during transcatheter edge-to-edge mitral valve repair (TMVR) can predict residual mitral regurgitation (MR) at discharge. BACKGROUND: In most patients, TMVR can successfully reduce MR from severe to mild or moderate. However, general anesthesia during the intervention affects hemodynamics and MR assessment. At discharge transthoracic echocardiogram residual MR (>moderate) is present in 10%-30% of patients which is associated with worse clinical outcome. METHODS: In consecutive patients the severity of MR was determined at baseline, immediately after TMVR clip implantation and subsequently during low-dose DSE (both under general anesthesia) and at discharge. RESULTS: A total of 39 patients were included (mean age 76.1 ± 8.1 years, 39% male, 56% functional MR, 41% left ventricular ejection fraction < 45%). An increase of MR during DSE was seen in 11 patients, of whom 6 (55%) showed >moderate MR at discharge. None of the 28 patients without an increase of MR during DSE showed >moderate MR at discharge. The diagnostic performance of the test could be established at a sensitivity of 100% and a specificity of 85% in unselected patients. CONCLUSIONS: DSE during TMVR is a useful tool to predict residual MR at discharge. It could support procedural decision making, including implantation of additional clips and thus potentially improve clinical outcome.

BACKGROUND: Acute myocardial infarction (AMI) with occlusion of an unprotected left main coronary artery (ULMCA) is a rare condition with a high mortality. The literature on clinical outcomes after percutaneous coronary intervention (PCI) for cardiogenic shock secondary to ULMCA-related AMI is scarce. METHODS: In this retrospective analysis, all consecutive patients undergoing PCI for cardiogenic shock secondary to total occlusive ULMCA-related AMI were included between January 1998 and January 2017. The primary endpoint was 30-day mortality. The secondary endpoints were long-term mortality and 30-day and long-term major adverse cardiovascular and cerebrovascular events. The differences in clinical and procedural variables were assessed. A multivariable model was created to search for independent predictors of survival. RESULTS: Forty-nine patients were included, and the mean age was 62 ± 11 years. The majority of patients suffered cardiac arrest prior or during PCI (51%). Thirty-day mortality was 78%, of which 55% died within 24 h. The median follow-up of patients who survived 30 days (n = 11) was 9.9 years (interquartile range 4.7-13.6), and long-term mortality was 84%. Long-term all-cause mortality was independently associated with cardiac arrest prior or during PCI (hazard ratio [HR] 2.02, 95% confidence interval 1.02-4.01, p = 0.043). Patients who survived to the 30-day follow-up with severe left ventricular dysfunction had a significantly higher risk of mortality compared to patients with moderate to mild dysfunction (p = 0.007). CONCLUSIONS: Cardiogenic shock secondary to total occlusive ULMCA-related AMI carries a very high 30-day all-cause mortality. Thirty-day survivors with a severe left ventricular dysfunction have a poor long-term prognosis.
