Estimated health effect, cost, and cost-effectiveness of mandating sodium benchmarks in Australia's packaged foods: a modelling study

Excess dietary sodium is a leading cause of death and disability globally. Because packaged foods are a major source of sodium in many countries, including Australia, mandatory limits for sodium might improve population health. We aimed to estimate the long-term health and economic effect of mandating such thresholds in Australia. We used a multiple cohort, proportional, multistate, life table model to simulate the effect of mandating either the WHO global sodium benchmarks or the currently non-mandatory Australian Healthy Food Partnership (HFP) sodium targets. We compared maintaining the current sodium intake status quo with intervention scenarios, using nationally representative data on dietary intake, sodium in packaged foods, and food sales volume. Blood pressure and disease burden data were obtained from the Global Burden of Diseases, Injuries, and Risk Factors Study. The effect of sodium reduction on blood pressure and disease risk was modelled on the basis of meta-analyses of randomised trials and cohort studies. Intervention and health-care costs were used to calculate the incremental cost per health-adjusted life-year (HALY) gained. Costs and HALYs were discounted annually at 3%. Compared with the status quo intervention, mandating the WHO benchmarks could be cost saving over the first 10 years (AUD$223 [95% uncertainty interval 82-433] million saved), with 2743 (1677-3976) cardiovascular disease deaths and 43 971 (26 892-63 748) incident cardiovascular disease events averted, and 11 174 (6800-16 205) HALYs gained. Over the population's lifetime, the intervention was cost effective (100·0% probability). Mandating the HFP sodium targets was also estimated to be cost effective (100·0% probability), but with 29% of the health benefits compared with the WHO benchmarks. Our modelling study supports mandating sodium thresholds for packaged foods as a cost-effective strategy to prevent death and disease in Australia. Although making Australia's voluntary reformulation targets mandatory might save thousands of lives, mandating the WHO global benchmarks could yield substantially greater health gains. None.

Evaluation of Small Vessel Bifurcation Stenting Using the Double-Kissing Culotte and Culotte Technique in Acute Coronary Syndrome: 12-Month Clinical Outcomes.

Patients with small vessels who undergo percutaneous coronary intervention (PCI) with subsequent multiple implantation of drug-eluting stents remain at a higher risk of unfavorable outcomes. In complex cases where maintaining flow to all side branches is part of contemporary practice, using two-stent techniques may be appropriate. This study aims to evaluate the efficacy of double-kissing (DK) culotte technique in comparison to culotte technique in the context of small-vessel therapy in patients with acute coronary syndrome (ACS). This substudy of the Lower Silesia culotte Bifurcation Registry retrospectively analyzed patients who underwent ACS-PCI using DK culotte or culotte technique for bifurcation lesions in small vessels, defined as having at least one branch with a diameter of 2.75 mm or less. The primary endpoint was target lesion failure (TLF), a composite of cardiovascular death, target vessel myocardial infarction, or clinically driven target lesion revascularization (TLR) at 1-year follow-up. The secondary endpoint included major adverse cardiac events (MACE). The DK culotte group (n = 49) and the culotte group (n = 52) were compared, with 12-month follow-up showing lower TLF in the DK culotte group (8.2% vs. 19.2%, p = 0.082). Similar results were observed for TLR (6.1% vs. 13.5%; p = 0.161), stent restenosis (4.1% vs. 9.6%; p = 0.203), and MACE (18.4% vs. 25%; p = 0.344). For bifurcation lesions with a small-diameter artery, the DK culotte technique may reduce TLF and MACE compared to the culotte technique. However, given the limited sample size and the absence of statistical significance, these findings remain preliminary and require further investigation.

Insulin Resistance-Nutritional Index: A Simple Index and Potential Predictor of Mortality Risk in Patients with Chronic Heart Failure and Type 2 Diabetes.

Patients with chronic heart failure (CHF) and type 2 diabetes mellitus (DM) are prone to insulin resistance and malnutrition, both of which are significant prognostic factors for CHF. However, the combined effect of the triglyceride-glucose index (TyG index) and prognostic nutritional index (PNI) on the mortality risk in patients with CHF and type 2 DM has not yet been studied. We enrolled 3,315 patients with CHF and type 2 DM. We used a multivariate Cox regression model to assess hazard ratios (HRs) with 95% confidence intervals (CIs) for mortality risk based on TyG index and PNI levels. Furthermore, we constructed a novel index, the insulin resistance-nutritional index (IRNI), defined as TyG index/Ln (PNI), and evaluated its prognostic significance. During follow-up, 1,214 deaths occurred. Participants with a high TyG index and non-high PNI had a significantly higher mortality risk compared to those with a non-high TyG index and high PNI, with an adjusted HR of 1.91 (95% CI, 1.57-2.32). The multivariate Cox regression analysis revealed HRs for all-cause and cardiovascular deaths of 1.93 (95% CI, 1.66-2.26; P < 0.001) and 2.50 (95% CI, 2.05-3.06; P < 0.001), respectively, when comparing the highest and lowest IRNI tertiles. IRNI's predictive power was stronger in groups with higher adapted Diabetes Complications Severity Index scores (P for interaction < 0.05). Additionally, adding IRNI to the baseline risk model significantly improved predictive performance, showing a greater effect compared to the TyG index or PNI. IRNI, a novel and composite index reflecting insulin resistance and nutritional status, emerges as a potentially valuable prognostic marker for patients with CHF and type 2 DM.

Win Ratio Analyses Using a Modified Hierarchical Composite Outcome: Insights from PARAGLIDE-HF

The win ratio (WR) is an emerging alternative for reporting composite outcomes, prioritizing clinically significant events such as mortality while incorporating surrogate measures. However, its benefits should be weighed against limitations, particularly the influence of lower hierarchical outcomes. This secondary analysis of the PARAGLIDE-HF trial performed a WR sensitivity analysis using a modified hierarchical composite outcome to assess the utility of WR sensitivity analysis and the efficacy of sacubitril/valsartan versus valsartan. PARAGLIDE-HF compared sacubitril/valsartan with valsartan in heart failure (HF) patients with ejection fraction >40% (N=466). A hierarchical outcome in the primary analysis included cardiovascular death, HF hospitalizations, urgent HF visits, and change in N-terminal pro-B-type natriuretic peptide (NT-proBNP), with a 25% decrease considered a win. In the pre-specified subgroup with ejection fraction ≤60% (N=357), sacubitril/valsartan showed a treatment effect on the hierarchical outcome (WR, 1.46; 95% CI, 1.08-1.97). Sensitivity analyses for this subgroup included: 1) excluding NT-proBNP change, 2) substituting the 25% proportion change of NT-proBNP with 10% or 50%, and 3) including renal outcomes within the hierarchical outcome. In addition to the WR, the win odds (WO), in which 50% of the ties are allocated to both the numerator and denominator of the WR-a potentially more suitable modification of the WR that accounts for the presence of ties-were presented. Excluding NT-proBNP (WR, 1.49; 95% CI, 1.00-2.22; WO, 1.12; 95% CI, 1.00-1.26), adjusting the NT-proBNP threshold from 25% to 10% or 50% (WR, 1.41; 95% CI, 1.06-1.89; WO, 1.27; 95% CI, 1.04-1.56 for 10%; and WR, 1.54; 95% CI, 1.11-2.12; WO, 1.25; 95% CI, 1.06-1.48 for 50%), and incorporating renal outcomes (WR, 1.44; 95% CI, 1.07-1.94; WO, 1.28; 95% CI, 1.05-1.56) consistently favored sacubitril/valsartan. Multiple WR sensitivity analyses support a consistent treatment benefit of sacubitril/valsartan versus valsartan in patients with ejection fraction >40% to 60%. Future studies could consider prespecifying WR sensitivity analysis for comprehensive assessment of treatment effects.

Does atrial fibrillation ablation prevent cardiovascular death, stroke, and heart failure events?

Does atrial fibrillation ablation prevent cardiovascular death, stroke, and heart failure events?

Smoking Cessation and Incident Cardiovascular Disease

The association between smoking cessation and cardiovascular disease (CVD) risk in relation to cumulative smoking exposure remains poorly understood. To evaluate the associations among smoking cessation, lifetime smoking burden, and CVD risk according to the number of years elapsed after smoking cessation. This retrospective cohort study of the Korean National Health Insurance Service database investigated smoking duration and intensity between January 2006 and December 2008. Participants were categorized by self-reported smoking habits as current, ex-, or never-smokers. Smoking records were updated every 2 years until December 2019, with participants whose smoking status changed or whose smoking status was unclear excluded. Data analysis was performed between June and December 2022. Time-updated self-reported smoking status, years since quitting, and cumulative smoking amount (pack-years [PY]). The primary outcome was incidence and hazard ratio of CVD (composite of cardiovascular death, myocardial infarction, stroke, and heart failure). Overall, 5 391 231 participants (39.9% male; mean [SD] age, 45.8 [14.7] years; 853 756 [15.8%] current smokers, 104 604 [1.9%] ex-smokers, and 4 432 871 [82.2%] never smokers) were followed up for a mean (SD) of 4.2 (4.4) years. The median (IQR) baseline cumulative smoking amounts were 14.0 (7.5-20.0) PY in current smokers and 10.5 (5.3-20.0) PY in ex-smokers. The median (IQR) duration of smoking cessation was 4 (2-8) years for ex-smokers. Regardless of continued smoking, a dose-dependent association was evident between smoking and incident CVD. Compared with current smokers, ex-smokers with a lifetime smoking burden of less than 8 PY (light ex-smokers) experienced a significant reduction in CVD risk within 10 years of cessation, with a CVD risk similar to that of never-smokers. Conversely, ex-smokers with at least 8 PY (heavy ex-smokers) exhibited a slower decline in CVD risk than light ex-smokers, requiring more than 25 years for the residual CVD risk to disappear. In this cohort study, smoking and CVD risk exhibited a dose-dependent association, with light ex-smokers having a CVD risk similar to that of never-smokers relatively soon after smoking cessation. For heavy ex-smokers, greater than 25 years might be required for the residual CVD risk to align with that of never-smokers.

Long-term cardiovascular outcomes of immune checkpoint inhibitor-related myocarditis: A large single-centre analysis.

Immune checkpoint inhibitors (ICI) are the cornerstone of modern oncology; however, side effects such as ICI-related myocarditis (irM) can be fatal. Recently, Bonaca proposed criteria for irM; however, it is unknown if they correlate well with cardiovascular (CV) ICI-related adverse events. Additionally, whether incident irM portends worse long-term CV outcomes remains unclear. We aimed to determine the incidence of long-term CV comorbidities and CV mortality among irM patients. The ICI-related adverse event (irAE) registry was queried to identify irM patients by using Bonaca criteria. Random controls were selected after excluding patients with other concomitant irAEs. Patients' demographics, comorbidities and myocarditis presenting features were gathered. Outcomes included 2-year freedom from CV comorbidities (composite of atrial fibrillation, stroke, myocardial infarction and heart failure) and freedom from CV death. IrM was treated as a time-varying covariate. Seventy-six patients developed irM at a median of 167days (mean age 69, 63.2% male, 47% lung cancer). Majority of patients had new wall motion abnormalities or EKG changes on presentation. Mean LVEF was 43%, median peak TnT was 0.81, and median NTproBNP was 2057 at irM onset. Two-year freedom from CV comorbidities (67% vs 86.8%, P<0.001) and death (93.4% vs 99.3%, P=0.003) was lower among irM patients. Incident irM was an independent predictor of CV death (HR 8.28, P=0.048), but not CV comorbidities (HR 2.21, P=0.080). This is the largest case-control study on irM highlighting worse long-term CV outcomes. Future studies are needed to establish appropriate therapeutic strategies and efficient screening strategies for irM survivors.

Carotid plaque thickness predicts cardiovascular events and death in patients with chronic kidney disease

BackgroundClassical risk scoring systems underestimate the risk of cardiovascular disease in chronic kidney disease (CKD). Coronary artery calcium score (CACS) has improved prediction of cardiovascular events in patients with CKD. The maximal carotid plaque thickness (cPTmax) measured in ultrasound scans of the carotid arteries has demonstrated similar predictive value as CACS in the general population. This is the first study to investigate whether cPTmax can predict cardiovascular events in CKD and to compare the predictive value of cPTmax and CACS in CKD.MethodTwo hundred patients with CKD stage 3 from the Copenhagen CKD Cohort underwent ultrasound scanning of the carotid arteries. The assessment consisted of locating plaque and measuring the thickest part of the plaque, cPTmax. Based on the distribution of cPTmax, the participants were divided into 3 groups: No plaques, cPTmax 1.0–1.9 mm and cPTmax > 1.9 mm (median cPTmax = 1.9 mm among patients with plaques). To measure CACS, 175 of the patients underwent a non-contrast CT scan of the coronary arteries. The follow-up time spanned between the ultrasound scan and a predefined end-date or the time of first event, defined as a composite of major cardiovascular events or death of any cause (MACE).ResultsThe median follow-up time was 5.4 years during which 45 patients (22.5%) developed MACE. In a Cox-regression adjusted for classical cardiovascular risk factors, patients with cPTmax > 1.9 mm had a significantly increased hazard ratio of MACE (HR 3.2, CI: 1.1–9.3), p = 0.031) compared to patients without plaques. C-statistics was used to evaluate models for predicting MACE. The improvement in C-statistics was similar for the two models including classical cardiovascular risk factors plus cPTmax (0.247, CI: 0.181–0.312) and CACS (0.243, CI: 0.172–0.315), respectively, when compared to a model only controlled for time since baseline (a Cox model with no covariates).ConclusionOur results indicate that cPTmax may be useful for predicting MACE in CKD. cPTmax and CACS showed similar ability to predict MACE.

Evaluating the budget impact of Empagliflozin in managing heart failure with reduced ejection fraction: Proposing strategic policies for Malaysian public healthcare.

Sodium-glucose co-transporter-2 (SGLT2) inhibitors such as Empagliflozin, are increasingly recommended as part of guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) in many developed nations. This recommendation is based on robust clinical evidence showing that adding Empagliflozin to GDMT improves heart failure symptoms, clinical outcomes, functional status, and overall quality of life. In Malaysia, where healthcare is predominantly public and heavily subsidized, the introduction of new treatments can significantly impact costs, requiring detailed economic assessments. This study evaluates the budget impact of incorporating Empagliflozin into GDMT for HFrEF from the perspective of the public healthcare system. A five-year budget impact model was developed, integrating local data such as population, drug use, costs, clinical outcomes, and healthcare expenses. In the current scenario (GDMT alone), the projected five-year expenditure is MYR 6.12 billion (USD 3.92 billion). With Empagliflozin, the total cost rises by 0.71% to MYR 6.16 billion (USD 3.95 billion), driven by drug acquisition costs of MYR 160.12 million (USD 102.64 million) and adverse event costs of MYR 211,543 (USD 135,604). However, these costs are offset by savings from reduced HF hospitalizations, fewer cardiovascular deaths, and improved renal outcomes. Sensitivity analysis identified hospitalization costs, the price of Empagliflozin, and cardiovascular deaths in diabetic patients as key factors influencing the budget impact. Policymakers can improve the affordability of Empagliflozin through strategies like price negotiations, cost-sharing, and focusing on high-risk groups to optimize healthcare expenditure while ensuring effective treatment access.

Cardiovascular effects of obstructive sleep apnoea and effects of continuous positive airway pressure therapy: evidence from different study models

INTRODUCTIONCardiovascular consequences of obstructive sleep apnoea (OSA) and the effects of continuous positive airway pressure (CPAP) therapy on blood pressure, endothelial dysfunction, and MACE (major adverse cardiovascular events) have been studied over decades using different study designs. However, clinical findings from different study models on cardiovascular outcomes are sometimes contradictory.METHODSA literature search was conducted in PubMed for randomised controlled trials, meta-analyses, population-based epidemiological studies and OSA cohort studies up to September 2023 investigating the cardiovascular effect of OSA and CPAP in adults with OSA on the following cardiovascular endpoints: blood pressure, arterial hypertension, endothelial function, and MACE (myocardial infarction, stroke, transient ischemic attack, cardiovascular death). The level of evidence for these outcomes was discussed on the basis of different study models.RESULTS AND CONCLUSIONSThere is high-level evidence of a causal relationship between OSA and arterial hypertension and endothelial dysfunction, as well as on higher MACE incidence among subgroups of patients with untreated OSA. The cardiovascular effects of OSA depend on the severity of OSA, symptoms, phenotype, and comorbidities. The blood pressure-lowering effect of CPAP is mainly observed in uncontrolled and treatment-resistant hypertension. The MACE risk reduction in OSA depends on good long-term CPAP adherence. Younger, sleepy patients with more severe OSA, higher hypoxaemic burden and without overt cardiovascular end-organ disease may particularly benefit from CPAP treatment in terms of cardiovascular risk reduction. Randomised controlled trials of CPAP or other effective OSA treatments in primary cardiovascular prevention and in patients at highest risk are lacking.

Vericiguat Global Study in Participants with Chronic Heart Failure: Design of the VICTOR trial.

In the VICTORIA (Vericiguat Global Study in Subjects with Heart Failure with Reduced Ejection Fraction) trial, the soluble guanylate cyclase stimulator vericiguat reduced the risk of hospitalization for heart failure (HHF) or cardiovascular death in patients with heart failure (HF) and reduced ejection fraction (HFrEF) with recent worsening HF. The effect of vericiguat in patients with HFrEF without recent worsening HF remains unknown. The VICTOR (Vericiguat Global Study in Participants with Chronic Heart Failure) trial was designed to assess the efficacy and safety of vericiguat in patients with ejection fraction ≤40% without recent worsening HF on a background of current foundational HFrEF therapy. The primary endpoint for VICTOR is time to first event for the composite of HHF or cardiovascular death. The trial will also assess the effect of vericiguat on time to cardiovascular death, time to HHF, total HHF, and all-cause death. As an event-driven trial, at least 1080 primary events are expected, but follow-up will continue until the targeted number of at least 590 cardiovascular deaths has been reached. Approximately 6000 participants will be randomized to vericiguat or placebo. VICTOR is the first large event-driven HFrEF trial performed in the contemporary era of quadruple foundational guideline-directed medical therapy, in a compensated ambulatory HF population. VICTOR will add important information to the evidence of the effects of vericiguat across the spectrum of patients with HFrEF.

Acute Myocardial Infarction in the Context of Diabetic Ketoacidosis: Pathophysiological Interactions, Clinical Manifestations, and Therapeutic Considerations

Acute myocardial infarction (AMI) and diabetic ketoacidosis (DKA) are two critical conditions that can coexist with significant morbidity and mortality. AMI is a leading cause of cardiovascular death, while DKA is a severe complication of uncontrolled diabetes mellitus, characterized by hyperglycemia, metabolic acidosis, and ketonemia. The convergence of these conditions presents unique challenges in diagnosis and management, as the metabolic disturbances of DKA can exacerbate myocardial ischemia and contribute to poor clinical outcomes. This article aims to explore the pathophysiological interplay between AMI and DKA, focusing on their shared risk factors, metabolic derangements, and the impact of hyperglycemia and ketosis on myocardial oxygen supply and demand. Furthermore, we discuss the clinical presentation, diagnostic strategies, and therapeutic approaches tailored to this dual pathology. Early recognition and prompt intervention are crucial to improving prognosis in patients with coexisting AMI and DKA. Multidisciplinary management involving cardiologists, endocrinologists, and intensivists is essential to mitigate the adverse outcomes of this complex clinical scenario.

Sodium-glucose cotransporter-2 inhibitors in acute myocardial infarction: a systematic review and meta-analysis of randomized controlled trials.

We aimed to assess the efficacy and safety of sodium-glucose cotransporter-2 inhibitors (SGLT2i) versus placebo, initiated within the hospitalization period, in addition to habitual treatment, for treating adult patients with confirmed acute myocardial infarction (AMI). We also conducted subgroup analysis by diabetes mellitus (DM) status and type of AMI. We systematically searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs). The primary outcome was hospitalization for heart failure (HF). The secondary outcomes were all-cause death, cardiovascular death, and serious adverse events (AEs). We pooled risk ratios (RR) with a 95% confidence interval (CI) for binary outcomes. The between-study variance was assessed using tau2 statistics. We included five RCTs, encompassing 11,211 patients. SGLT2i significantly reduced the risk of hospitalization for HF compared to placebo (RR 0.73; 95% CI [0.61, 0.88]). However, the risk of all-cause death (RR 1.05; 95% CI [0.78, 1.41]) and cardiovascular death (RR 1.04; 95% CI [0.84, 1.29]) was similar between the groups, as well as the risk of serious AEs (RR 1.01; 95% CI [0.90, 1.14]). In the subgroup analysis by DM status and type of AMI, there were no significant subgroup differences for the outcomes of hospitalization for HF and all-cause death. In patients with AMI, treatment with SGLT2i is safe and significantly reduces the risk of hospitalization for HF, but it has no impact on all-cause death and cardiovascular death compared to placebo.

Association of prophylactic low-dose aspirin use with all-cause and cause-specific mortality in cancer patients

The long-term use of aspirin for preventing cardiovascular disease has been recommended for decades. However, there is currently uncertainty regarding the long-term effects of aspirin use on the risk of all-cause, cardiovascular, and cancer mortality in cancer patients. The aim of this work was to analyze the connection between the prophylactic use of low-dose aspirin and the risk of all-cause death, cardiovascular death, and carcinoma death in carcinoma patients in the United States. A cohort study was conducted using National Health and Nutrition Examination Survey (NHANES) data (2011–2012, 2013–2014, 2015–2016, and 2017–2018) and associated mortality data. The 95% confidence intervals (CIs) and hazard ratios (HRs) between non-aspirin use and prophylactic low-dose aspirin use and the risk of death were measured via Cox proportional hazard regression models. A total of 1819 participants were included in the present research, of whom 945 were nonaspirin users and 874 were prophylactic aspirin users. Compared with non-aspirin users, prophylactic low-dose aspirin users had a decreased risk of all-cause death (HR = 0.647, 95% CI = 0.489–0.857). There was no statistically significant difference in the risk of cardiovascular death (HR = 0.623, 95% CI = 0.362–1.074) or cancer death (HR = 0.709, 95% CI = 0.410–1.226). Prophylactic use of low-dose aspirin may lower all-cause mortality in individuals with cancer but does not have a substantial effect on cardiovascular risk or cancer-specific mortality in this patient population.

Effects of age, sex, daily dose, comorbidity and co-medication on venlafaxine-associated cardiovascular adverse events: A pharmacovigilance analysis of the FDA Adverse Event Reporting System database.

This study aimed to provide a comprehensive view of cardiovascular adverse events (AEs) associated with venlafaxine (VEN) therapy. Cardiovascular AE reports for patients receiving VEN therapy were retrieved from January 2004 to December 2023 from the FDA Adverse Event Reporting System database. Effects of age, sex and daily VEN dose on the occurrence of different types of cardiovascular AEs and the influence of demographics, VEN dose, comorbidity and co-medication on death in patients with cardiovascular AEs were analysed by multivariate logistic regression analysis. The study included 16 110 AE reports following VEN treatment (median age: 51 years, females: 69.78%, median VEN daily dose: 100 mg/day). VEN daily dose was associated with increased risks of cardiac arrhythmias, embolic and thrombotic events, torsade de pointes/QT prolongation, ischaemic heart disease, cardiac failure, cardiomyopathy and overall cardiovascular events. The elderly (≥ 75 years), male sex, comorbidity (infections and infestations, cardiac disorders, nervous system disorders) and co-medication (quetiapine and clozapine) were related to death following VEN-associated cardiovascular AEs; however, the risk of cardiovascular death did not increase with regular VEN doses. Our study confirmed the association of cardiovascular AEs with VEN therapy and revealed the influencing factors for the risk of VEN-related cardiovascular AEs and death due to these events. Based on the obtained evidence, the cardiovascular health of late-elderly patients with complex comorbidity and polytherapy should be closely monitored when they receive VEN therapy. As an exploratory study, prospective studies are needed to validate our findings in the future.

Reproductive factors predict risks of cardiovascular disease and premature death in postmenopausal women with type 2 diabetes: The Fukuoka Diabetes Registry

AimsReproductive factors (reproductive period, age at menarche, and age at menopause) are associated with a risk of cardiovascular disease (CVD) and death in individuals without focusing on comorbid diabetes. However, it remains unclear whether this association also applies to individuals with diabetes. This study investigated the relationship between reproductive factors and the risk of CVD and death in postmenopausal Japanese women with type 2 diabetes. Methods1,592 postmenopausal women with type 2 diabetes without pre-existing CVD were subclassified based on reproductive period (age at menopause minus age at menarche). The primary outcome was a composite of CVD incidence and all-cause death. ResultsThe risk of the outcome decreased with a longer reproductive period. Compared with a reproductive period of ≤ 29 years, the multivariable-adjusted hazard ratios (95 % CI) were 0.80 (0.39–1.66), 0.73 (0.37–1.43), and 0.43 (0.19–0.99) for reproductive periods of 30–34, 35–39, and ≥ 40 years, respectively (p for trend = 0.046). Earlier age at menarche and later age at menopause were also associated with a decreased risk of the outcome. ConclusionsEvaluating reproductive factors may help predict the risks of CVD and death in postmenopausal women with type 2 diabetes.

Comparative Influences of Beta blockers and Verapamil on Cardiac Outcomes in Hypertrophic Cardiomyopathy

Guidelines recommend β blockers (BBs) as first-line therapy in symptomatic patients with hypertrophic cardiomyopathy (HCM) and nondihydropyridine calcium channel blockers, particularly, verapamil, as the second-line therapy, despite the absence of comparison trials between those 2 drugs. Because deleterious effects of verapamil have been reported in this setting, the present analysis aimed to evaluate the prognostic impact of BBs and verapamil in a cohort of patients with HCM. From a nationwide cohort of 1,434 patients with a diagnosis of HCM included in the French prospective observational REgistry of hypertrophic cardioMYopathy (REMY), we retrospectively analyzed patients with sarcomeric HCM included in the 3 largest centers and treated either with BBs or verapamil. Patients with a cardiac defibrillator or a pacemaker or who underwent a procedure of atrial fibrillation or septal ablation were excluded. The primary end point was the composite of cardiovascular death, hospitalization for heart failure, and hospitalization for atrial fibrillation. Of 600 patients with HCM, 544 (91%) were treated with BBs and 56 (9%) with verapamil. At inclusion, the 2 groups were comparable concerning the presence/amplitude of obstruction and sudden cardiac death risk factors. At up to 8 years of follow-up (median 3.9 years, interquartile range 2.1 to 5.8), no significant differences were observed in the primary end point (132 [24%] vs 10 [18%] under BBs or verapamil, respectively, hazard ratio 1.84, 95% confidence interval 0.94 to 3.63). In conclusion, in a real-world cohort of low-risk patients with HCM, verapamil therapy was not associated with a higher incidence of adverse events than β-blocker therapy.

Contemporary outcomes of catheter ablation of the structural ventricular tachycardias in severe ischemic and non‐ischemic cardiomyopathies in Turkish population

AbstractIntroductionCurrently, there are no data regarding outcomes of the catheter ablation for structural ventricular tachycardia (VT) in Türkiye. In this observational study, we aim to investigate cardiac outcomes of patients undergoing catheter VT ablation at a tertiary center in Türkiye.MethodsThis was a retrospective observational study performed at a single university center. Patients with a confirmed ischemic or non‐ischemic cardiomyopathy, undergoing structural VT ablation were included. Procedural and mid‐term outcomes were analyzed.ResultsA total of 124 patients were enrolled in the study. 54(43.5%) patients presented with an electrical storm. During the mean follow‐up of 351 ± 232 days 10(8.1%) patients experienced a recurrence. There was only one peri‐procedural death and cardiac tamponade occurred in two patients.14(11.3%) patients died during the follow‐up, most commonly due to a cardiovascular death. In the multivariate analysis only age &gt;70 was found to be correlated with death during follow‐up, with p =.008, HR = 4.923.ConclusionA good acute success with low complications was observed in patients undergoing VT ablation for structural heart disease in a tertiary center in Türkiye. Mid‐term outcomes are comparable with international studies with no difference in VT recurrence in ischemic and non‐ischemic patients. Similar to international studies, significant mid‐term mortality was observed.

Impact of Triglyceride Levels on the Long-term Clinical Outcomes in Patients With Acute Myocardial Infarction.

Hypertriglyceridemia is a known cardiovascular risk factor. However, the relationship between serum triglyceride (TG) levels and the clinical outcomes in patients with acute myocardial infarction (AMI) is unclear. We conducted a single-center, retrospective observational study involving 538 consecutive patients with AMI who underwent emergent percutaneous coronary intervention within 12 hours of onset. Patients were categorized into three groups based on their serum TG levels at admission as follows: T1 group (TG <78 mg/dl, n=172), T2 group (78≤TG<141 mg/dl, n=177), and T3 group (141 mg/dl ≤TG, n=176). The primary endpoint was major adverse cardiovascular events (MACEs) defined as a composite of cardiovascular death, non-fatal MI, and non-fatal stroke. The median follow-up period was 2.4 (1.5-4.2) years. Patients in the T1 group were older, had a higher proportion of females, and had fewer cardiovascular risk factors. However, they also had a higher prevalence of multi-vessel coronary artery disease and severely calcified culprit lesions. The T1 group had a significantly higher rate of MACEs (20.4% in T1, 12.4% in T2 and 8.5% in T3, p<0.05 by Log-rank test, respectively). Multivariate analysis revealed that T1 was an independent predictor of MACEs (hazard ratio=2.19, 95% confidence interval=1.16-4.14, p<0.05). Although patients with AMI with low TG levels at admission had fewer coronary risk factors, they had more severe calcified culprit lesions and worse clinical outcomes.

Effect of body mass index on mortality for diabetic patients with aortic stenosis

Abstract Background Several studies suggest an "obesity paradox," associating obesity with better cardiovascular outcomes compared to normal or underweight individuals (1-3). Purpose This study explores the impact of body mass index (BMI) on mortality in patients with diabetic mellitus (DM) and aortic stenosis (AS). Methods This is a retrospective cohort study conducted at a tertiary centre. Between 2014 and 2019, patients with DM who underwent echocardiography were screened (4). Patients were enrolled if AS was diagnosed, according to established guidelines (5). Two echocardiography specialists independently reviewed the echocardiography in the cohort. The index date of the DM-AS cohort was the first AS diagnosis by echocardiography, and detailed data collection methods are described in previous studies (6,7). Patients were categorized as underweight, normal weight, or obese based on BMI (&amp;lt;18.5, 18.5 to 27, and &amp;gt;27 kg/m2, respectively). Outcomes included all-cause mortality, cardiovascular, and non-cardiovascular death, which were adjudicated by a central committee. The occurrence times of the outcomes of interest were determined using diagnosis codes from electronic health records, and medical records were reviewed until the last clinical visit or death. Results Among 74,835 DM patients, 734 had AS. Normal weight comprised 65.5% (n=481), underweight 4.1% (N=30), and 30.4% were obese. With a median follow-up time of 34 months, 285 patients (38.8%) experienced outcomes of death, comprising 93 patients (32.7%) with cardiovascular death and 192 patients (67.3%) with non- cardiovascular death. Underweight patients had significantly higher all-cause mortality (HR 1.96, 95% CI 1.22 – 3.14, p = 0.005), while obese patients had significantly lower mortality (HR 0.79, 95% CI 0.68 - 0.91, p=0.001) compared to the normal group. Regarding etiologies, underweight patients had a higher risk of non- cardiovascular death (HR 2.47, 95% CI 1.44-4.25, p = 0.001), while obese patients had a lower risk of cardiovascular death (HR 0.66, 95% CI 0.50-0.86, p=0.003). Subgroup analysis showed a consistent trend without significant interaction. To elucidate the interaction of BMI as a continuous variable with outcomes, restricted cubic spline analysis was applied. Cardiovascular death showed a negative association with BMI across available BMI levels, and non-cardiovascular death exhibited a U curve, with the lowest hazard ratio occurring when BMI was between 25 to 30. Conclusion Our study underscored the significance of both cardiovascular and non-cardiovascular deaths as crucial contributors to overall mortality in DM patients with AS. Being underweight is associated with increased non- cardiovascular death, while obesity is linked to less cardiovascular death. Proposed mechanisms include reduced frailty, enhanced tolerance to guideline-directed medical therapies (GDMTs), and heightened disease awareness in the obese group (8,9).Kaplan–Meier analysis for outcomesAssociation between BMI and outcomes
