Objective: Multidisciplinary team (MDT) meetings are central to treatment decisions in aortic stenosis (AS), particularly for borderline or high-risk patients. This study evaluates long-term, real-world outcomes according to MDT-selected management strategy within routine clinical practice in this clinically important patient group.

Methods: We conducted a retrospective cohort study of all patients with severe AS discussed at a transcatheter aortic valve implantation (TAVI) MDT at a tertiary UK centre between January 2014 and December 2016. Patients were categorised as TAVI or non-TAVI (conservatively managed). Demographic, clinical and frailty data were collected, including Charlson Comorbidity Index, Clinical Frailty Scale (CFS) and number of prescribed medications. Survival was analysed using Kaplan-Meier estimates and Cox proportional hazards modelling adjusted for age, sex, frailty, comorbidity burden and medication count.

Results: A total of 373 patients were included (TAVI=178; non-TAVI=195). Patients undergoing TAVI were younger (81.3 years vs 83.5 years; p=0.01) and less frail (CFS 3.9 vs 4.9; p<0.01). Survival at 1 year, 2 years and 5 years was significantly higher following TAVI (87.6%, 74.7%, 44.9%) compared with conservative management (60.8%, 44.2%, 12.1%; p<0.001). Median survival was 53 months after TAVI versus 20 months without intervention. On multivariable analysis, TAVI was independently associated with reduced mortality (HR 0.38, 95% CI 0.28 to 0.50; p<0.001).

Conclusions: In patients with severe AS discussed at MDT, TAVI was associated with a substantial and durable survival advantage compared with conservative management. These findings highlight the poor prognosis of untreated severe AS and support systematic inclusion of conservatively managed patients in interventional registries to better inform MDT deliberation and shared decision-making.

Aims: The obesity paradox has been described in different cardiovascular conditions. Data on the association between obesity and outcomes in patients with Takotsubo syndrome (TTS) are lacking. The aim of this study was to determine the relationship between body weight and mortality in TTS patients.

Methods: Patients enrolled in the International Takotsubo Registry from January 2011 to July 2021 and with available data on body mass index (BMI) were included in the analysis. Patients were stratified according to BMI (underweight, <18.5 kg/m²; normal weight, 18.5-24.9 kg/m²; overweight, 25.0-29.9 kg/m²; obese, 30.0-34.9 kg/m²; and very obese, ≥35.0 kg/m²). The primary endpoint was mortality at 1 year.

Results: Of the 2707 patients, 222 (8.2%) were underweight, 1340 (49.5%) of normal weight, 759 (28.0%) overweight, 268 (9.9%) obese and 118 (4.4%) very obese (p=0.02). Rates of mortality at 1 year were 11.3%, 6.9%, 5.5%, 4.9% and 9.3% in underweight, normal weight, overweight, obese and very obese patients (p=0.02). Being overweight or obese was significantly associated with a lower mortality rate at 1 year (HR 0.70, 95% CI 0.51 to 0.96, p=0.03), and this association remained significant after multivariable adjustments (adjusted HR 0.67, 95% CI 0.46 to 0.97, p=0.03).

Conclusion: A U-shaped mortality curve across BMI categories was observed in TTS patients, with the highest mortality rates observed in underweight and the lowest rates observed in obese patients. These observations provide the first evidence for the existence of the obesity paradox in TTS.

Background: There is a lack of contemporary data describing patients with left ventricular (LV) systolic dysfunction post myocardial infarction (MI) in terms of symptom burden and secondary prevention measures. The aim of this study was to describe patients with various degrees of LV systolic dysfunction after a first MI, their symptom burden, quality of life and adherence to recommended secondary prevention measures in a nationwide patient material.

Methods: Patients (n=49 564) registered in the Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease registry between 2011 and 2018, diagnosed with a first acute MI, discharged alive and with no previous heart failure, were stratified by degree of LV systolic dysfunction.

Results: Compared with patients with normal ejection fraction (EF≥50%), patients with a reduced EF (<30%) more often experienced shortness of breath (32.3% vs 5.6%, adjusted OR (95% CI): 7.45 (6.22 to 8.92)), had more often been readmitted (48.1% vs 31.2%, 1.87 (1.61 to 2.19)) and were more often on sick leave (26.6% vs 9.5%, 3.35 (2.45 to 4.58)), whereas there were no significant differences regarding chest pain and quality of life at the follow-up visit after 11-13 months. Patients with EF <30% had participated in education programme (44.9% vs 55.5%, 0.70 (0.60 to 0.81)) and physical therapy (11.3% vs 14.9%, 0.68 (0.58 to 0.79)) and have been physically active at least 30 min per day for at least 5 days per week (35.5% vs 40.2%, 0.86 (0.73 to 1.01)) to a lesser extent.

Conclusion: Contemporary representative data show that LV systolic dysfunction after MI is associated with a very high symptom burden and worse secondary prevention after 11-13 months.

Objectives: To evaluate if an intervention to improve health literacy, using the risk communication tool 'Your Heart Forecast' and informative e-mails, can lower patients' blood pressure (BP) and total cholesterol to high-density lipoprotein ratio (TC/HDL).

Design: A cluster randomised controlled trial.

Setting: The intervention took place in 17 Danish general practice clinics randomised to either control or intervention at clinic level after invitation of each 25 hypertensive patients by birthdate.

Participants: Men and women were eligible for inclusion if 35-75 years old, without prior cardiovascular disease (CVD). The final population consisted of 255 patients, 142 intervention and 113 control. The 146 men and 109 women were included between April 2019 and May 2021. The trial ended in March 2022.

Intervention: The intervention consisted of the CVD-risk communication tool 'Your Heart Forecast' at the annual BP consultations plus 1 monthly educational e-mail on lifestyle for 12 months. The control group received the usual care, defined as the annual CVD risk management consultation.Main outcome measures, BP and TC/HDL, were measured at baseline and follow-up after 10-18 months. Patients were divided into groups based on baseline levels and a paired t-test was performed on a pseudorandomised dataset by a blinded statistician.

Results: Both groups' most dysregulated patients decreased their BP (p<0.0001, p=0.0002), and the BP decrease in the intervention group was larger. Additionally, the intervention patients with moderately raised BP also decreased their BP significantly (p=0.0133). Both groups saw an increase in BP in the most well-regulated patients. TC/HDL decreased only for the intervention patients with the highest baseline levels (p<0.0001) and increased for all with the lowest ratio (p<0.0001).

Conclusion: The intervention lowered BP and TC/HDL in comparison to usual care for patients with dysregulated BP and/or TC/HDL above 4.

Background: The benefits of minimally invasive mitral valve surgery (MIMVS) compared with conventional approaches (CMVS, conventional mitral valve surgery) remain controversial. We conducted a systematic review and meta-analysis to evaluate the short-term benefits between these approaches.

Objective: To evaluate the short-term benefits of MIMVS versus CMVS in adults.

Methods: We searched PubMed/MEDLINE, EMBASE, Cochrane Library, LILACS, SciELO, clinical trial registries and grey literature using MeSH terms, without date or language restrictions. Randomised clinical trials (RCTs) comparing MIMVS and CMVS in adults (≥18 years) were included. Robotic, endovascular and redo procedures were excluded. Two reviewers independently extracted data following Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Risk of bias was assessed with the Cochrane tool, and certainty of evidence with Grading of Recommendations, Assessment, Development and Evaluation. Meta-analyses used random-effects models. Primary outcomes were mortality, acute kidney injury (AKI) and wound infection.

Results: Nine studies (1248 patients) from eight RCTs were included (686 CMVS, 562 MIMVS). MIMVS showed no significant difference in mortality or AKI compared with CMVS. There was a trend towards fewer wound infections (risk ratio=0.47; 95% CI=0.22 to 1.00) and shorter intensive care unit (ICU) stay (mean difference=-0.71 days; 95% CI=-1.47 to 0.04). MIMVS reduced reoperation for bleeding (RR=0.24; 95% CI=0.06 to 0.92) and hospital stay (mean difference=-1.83 days; 95% CI=-3.03 to -0.64). Operative times were longer with MIMVS, but without clinical impact. Stroke, myocardial infarction, mechanical ventilation time and transfusion rates were similar. Most studies had low risk of bias, with moderate to high certainty of evidence. No heterogeneity was detected for primary outcomes.

Conclusion: MIMVS enhances postoperative recovery through shorter hospital stays, fewer reoperations for bleeding and a trend towards fewer wound infections and shorter ICU stays compared with CMVS. Despite longer operative times, key safety is comparable between techniques. The overall certainty of evidence is high for most outcomes, supporting strong clinical recommendations in favour of MIMVS.

Background: Cardiogenic shock (CS) complicating acute myocardial infarction (AMI) carries high mortality. Early revascularisation improves survival, but the effect of structured multidisciplinary care on outcomes remains underexplored.

Methods and results: ACT-SHOCK is a service evaluation at a UK tertiary cardiac centre. Between May 2023 and May 2024, 82 patients with AMI-related CS requiring emergent percutaneous coronary intervention (PCI) were identified using protocolised physiological criteria and managed by an Advanced Cardiogenic-Shock Team (ACT). The ACT comprised interventional cardiologists, intensivists, anaesthetists, critical care staff and cardiac physiologists, coordinating PCI and ongoing care. Outcomes were compared with 83 historical controls from the year preceding ACT roll-out, who received standard care without ACT activation. Primary endpoints were 30-day and 1-year all-cause mortality; secondary outcomes included predictors of 30-day mortality.Within the ACT cohort, elevated lactate, critical care admission, invasive ventilation, out-of-hospital cardiac arrest and Society for Cardiovascular Angiography and Interventions (SCAI) Shock Stage E at first medical contact predicted 1-year mortality. Adjusted analyses showed ACT management was associated with lower 1-year mortality compared with standard care (HR 0.53, 95% CI 0.30 to 0.92; p=0.026). Although 30-day mortality was lower in the ACT group, this did not reach statistical significance (HR 0.71, 95% CI 0.39 to 1.29; p=0.26). Escalation from coronary care to critical care during the recovery phase occurred more promptly in the ACT group (9.7% vs 2.4%, p=0.09). At 24 hours, a smaller proportion of ACT patients remained in SCAI stages D/E compared with standard care (42% vs 48%; p=0.003).

Conclusions: Implementation of physiological criteria to identify CS and activation of a multidisciplinary ACT in a UK tertiary centre was associated with earlier detection and improved 1-year survival in AMI-related CS. These pilot data support further study across multiple UK centres to inform national policy and standardise care pathways.

Background: Aortic dimensions are critical for assessing the risk of acute aortic complications and guiding surgical interventions. Current guidelines define absolute diameter thresholds based largely on Western cohorts, while data on Indian patients remain limited. To address this gap, our study provides a direct, large-scale comparison of aortic diameters between Indian and Dutch individuals to determine whether existing geometry-based surgical guidelines are equally applicable across populations.

Methods: In this retrospective cohort study, we analysed all consecutive patients who underwent CT imaging between January and December 2022 at SIMS Hospital (India) and Amsterdam University Medical Center (Netherlands). Aortic diameters were measured at five predefined anatomical locations: aortic root, ascending aorta, aortic arch, descending aorta and abdominal aorta. Multivariable linear regression models were used, adjusting for age, sex, height and comorbidities.

Results: A total of 3692 patients were included (2000 Indian and 1692 Dutch). Indian patients had a larger aortic root (33.9 ± 4.6 mm vs 31.5 ± 5.4 mm; p<0.001), whereas Dutch patients had significantly larger diameters of the ascending aorta (33.1 ± 5.4 mm vs 30.5 ± 4.3 mm; p<0.001), aortic arch (29.8 ± 4.5 mm vs 26.4 ± 3.7 mm; p<0.001), descending aorta (26.7 ± 4.2 mm vs 23.0 ± 3.9 mm; p<0.001) and abdominal aorta (23.1 ± 5.0 mm vs 21.3 ± 3.4 mm; p<0.001). These differences persisted after adjustment for age, sex, height and comorbidities.

Conclusions: In this first global comparison of ascending aortic dimensions between Indian and Dutch patients, we demonstrate substantial geographic heterogeneity. These findings highlight concerns about applying current surgical thresholds to Indian patients with aortopathy and emphasise the need for individualised risk assessment and treatment strategies in this population. Future guidelines should consider population-specific differences in India and incorporate indexed measurements to optimise personalised surgical decision-making.

Introduction: Inherited cardiac conditions, including dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM), may have a monogenic cause identified through genetic testing (GT). Confirmation of pathogenic gene variants can have important implications for the patient and their relatives. The UK National Genomic Test Directory (NGTD) provides strict criteria on the indications for GT; however, the European Society of Cardiology (ESC) recommends wider GT. We reviewed the prevalence of pathogenic genotypes in patients undergoing GT who did not meet the NGTD criteria.

Methods: We conducted a retrospective analysis of patients who underwent GT with a confirmed diagnosis of HCM or DCM attending the Essex Inherited Cardiac Conditions Clinic between January 2023 and January 2025.

Results: 257 patients were included in the analysis, with 136 patients with DCM (52.9%) and 121 patients with HCM (47.1%). The diagnostic yield of GT was 19.9% in DCM and 17.4% in HCM.14.8% of gene-positive patients with DCM and 14.3% of gene-positive patients with HCM did not meet current UK testing criteria, predominantly due to age of onset. All gene-positive patients in the DCM subgroup not meeting current NGTD criteria for testing had evidence of myocardial fibrosis.

Conclusion: A significant minority of patients (1 in 7) with cardiomyopathy and a pathogenic genotype did not meet current UK testing criteria; each patient has an average of 4 first-degree relatives at risk who will benefit from predictive GT. We propose the adoption of the wider ESC guidance, removing the strict age-related cut-offs and being guided more by the severity of the phenotype, particularly involving myocardial scarring.

Background: Biomarkers could improve risk stratification in patients with acute ST-segment elevation myocardial infarction (STEMI), beyond left ventricular ejection fraction (LVEF). Our study evaluated the association between N-terminal pro-B-type natriuretic peptide (NT-proBNP), C reactive protein (CRP) and mortality in a cohort of patients with acute STEMI.

Methods: This prospective, observational cohort study included patients with reperfused acute STEMI admitted to a tertiary cardiovascular disease centre between July 2020 and October 2023. All patients underwent NT-proBNP and CRP testing. The association between NT-proBNP, CRP and all-cause mortality was evaluated in relation to predischarge LVEF.

Results: The cohort included 566 patients with a mean age of 63 years. After a median follow-up of 39 months, postdischarge all-cause mortality reached 13.4%. NT-proBNP was associated with mortality irrespective of LVEF (HR 2.34 per SD increment in log NT-proBNP; p<0.001 at LVEF <50% and HR 2.36; p=0.004 at LVEF ≥50%), but the association between CRP and mortality was significant only in patients with LVEF <50% (HR 1.55, p=0.003). Across the cohort, NT-proBNP remained associated with death after adjustment for age, sex, diabetes, baseline high-sensitivity cardiac troponin T (hs-cTnT), CRP, final Thrombolysis in myocardial infarction (TIMI) flow grade and reduced LVEF (HR 1.45, p=0.03). In patients with preserved LVEF, routine NT-proBNP testing (area under the curve (AUC) 0.753 (0.642-0.863), p<0.001) improved risk stratification compared with isolated LVEF assessment (AUC 0.592 (0.453-0.730), p=0.18).

Conclusions: In a cohort of stabilised acute STEMI survivors, NT-proBNP was associated with all-cause mid-term mortality independent of hs-cTnT and LVEF. The association between CRP and mortality was significant only in patients with LVEF <50%.

Background: Fibrocalcific aortic valve sclerosis (AVSc), the earliest manifestation of aortic stenosis (AS), is increasingly recognised as a marker of systemic vascular damage and adverse cardiovascular outcomes. While a subset of AVSc patients progresses to AS, reported rates vary widely. We conducted a systematic review and meta-analysis to better define the natural history of AVSc progression.

Methods: Following Preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, we searched PubMed, Scopus and Web of Science through July 2025 for observational studies reporting AS development in AVSc patients. Primary outcomes were progression to any degree of AS and to severe AS. Pooled event rates were calculated using a random-effects model. Heterogeneity and publication bias were assessed using standard statistical methods. Meta-regression explored associations with clinical and demographic variables.

Results: Eight studies (n=12 388 patients) reported on the progression of AVSc patients to any AS stage, and nine studies (n=19 486 patients) on the progression to severe AS. Over a median follow-up of 4.0 years, 14.1% of AVSc patients progressed to any AS stage (effect size: 0.14; 95% CI 0.02 to 0.53), and 2.0% to severe AS (effect size: 0.02; 95% CI 0.003 to 0.094). Heterogeneity was high, but no publication bias was detected. Meta-regression found no significant predictors of progression.

Conclusions: Approximately one in six AVSc patients progresses to AS within 4 years, and 2% develop a severe disease. These findings underscore the importance of structured echocardiographic surveillance and support AVSc as a clinically relevant marker of systemic cardiovascular risk.
