- The prevalence of HF with preserved ejection raction (HFpEF, with EF >= 50%) is increasing across all populations with high rates of hospitalization and mortality, reaching up to 80% and 50%, respectively, within a 5-year timeframe. Comorbidity-driven systemic inflammation is thought to cause coronary microvascular dysfunction and increased epicardial adipose tissue, leading to downstream friborsis and molecular changes in the cardiomyocyte, leading to increased stiffness and diastolic dynsfunction. HFpEF poses unique challenges in terms of diagnosis due to its complex and diverse nature. The diagnosis of HFpEF relies on a combination of clinical assessment, imaging studies, and biomarkers. An additional important step in diagnosing HFpEF involves excluding certain cardiac diagnoses that may be specific underlying causes of HFpEF or may be masquerading as HFpEF and require specific alternative treatment approaches. In addition to administering sodium-glucose cotransporter 2 inhibitors to all patients, the most effective approach to enhance clinical outcomes may involve tailored therapy based on each patient's unique clinical profile. Exercise should be recommended for all patients to improve the quality of life. Glucagon-like peptide-1 1 agonists are a promising treatment option in obese HFpEF patients. Novel approaches targeting inflammation are also in early phase trials.

- Background: Discrimination of heart failure with preserved ejection fraction with pulmonary hypertension (HFpEF-PH) from pulmonary arterial hypertension (PAH) is crucial for clinical management but may be challenging due to similarities in clinical and comorbid characteristics. We aimed to investigate tumour and metabolism related proteins in differentiating HFpEF-PH from PAH. Methods: Sixty-nine tumour and metabolism plasma proteins were analysed with proximity extension assay in heathy controls (n = 20), patients with PAH (n = 48) and LHF-PH (n = 67) [HFpEF-PH (n = 31) and HF reduced EF-PH (n = 36)]. Haemodynamics were assessed with right heart catheterization. Results: The plasma levels of alpha-1-microglobulin/bikunin precursor (AMBP) and lipoprotein lipase (LPL), were higher in HFpEF-PH compared to healthy controls (p < 0.01), HFrEF-PH (p < 0.05), and PAH (p < 0.001). Glyoxalase I levels were higher in HFpEF-PH and HFrEF-PH compared to controls (p < 0.001) and PAH (p < 0.001). Each of plasma AMBP, LPL, and glyoxalase I, adjusted for age and sex in multivariable logistic regression models, could differentiate HFpEF-PH from PAH, with areas under the receiver operating characteristic curve (AUC) of 0.81, 0.84 and 0.79, respectively. The combination of AMBP, LPL and glyoxalse I yielded the largest AUC of 0.87 [95% confidence interval (0.79–0.95)] in discriminating HFpEF-PH from PAH, with a sensitivity of 87.1% and a specificity of 85.4%. In HFpEF-PH, the plasma levels of AMBP correlated with pulmonary arterial wedge pressure (rs = −0.42, p = 0.018). Conclusions: Plasma AMBP, LPL and glyoxalase I may facilitate the distinction of HFpEF-PH from PAH. Larger clinical studies are encouraged to confirm and validate our findings.

- Aims: To predict irreversible reduction in left ventricular ejection fraction (LVEF) during admission for ST-segment elevation myocardial infarction (STEMI) using cardiac magnetic resonance (CMR) in addition to classical clinical parameters. Irreversible reduction in LVEF is an important prognostic factor after STEMI which necessitates medical therapy and implantation of prophylactic implantable cardioverter defibrillator (ICD). Methods and results: A post-hoc analysis of DANAMI-3 trial program (Third DANish Study of Optimal Acute Treatment of Patients With ST-elevation Myocardial Infarction) which recruited 649 patients who had CMR performed during index hospitalization and after 3 months. Patients were divided into two groups according to CMR-LVEF at 3 months: Group 1 with LVEF≤35% and Group 2 with LVEF>35%. Group 1 included 15 patients (2.3%) while Group 2 included 634 patients (97.7%). A multivariate analysis showed that: Killip class >1 (OR 7.39; CI:1.47–36.21, P = 0.01), symptom onset-to-wire ≥6 h (OR 7.19; CI 1.07–50.91, P = 0.04), LVEF≤35% using index echocardiography (OR 7.11; CI: 1.27–47.43, P = 0.03), and infarct size ≥40% of LV on index CMR (OR 42.62; CI:7.83–328.29, P < 0.001) independently correlated with a final LVEF≤35%. Clinical models consisted of these parameters could identify 7 out of 15 patients in Group 1 with 100% positive predictive value. Conclusion: Together with other clinical measurements, the assessment of infarct size using late Gadolinium enhancement by CMR during hospitalization is a strong predictor of irreversible reduction in CMR_LVEF ≤35. That could potentially, after validation with future research, aids the selection and treatment of high-risk patients after STEMI, including implantation of prophylactic ICD during index hospitalization.

- Background: Geographic variations in management and outcomes of individuals supported by continuous-flow left ventricular assist devices (CF-LVAD) between the United States (US) and Europe (EU) is largely unknown. Methods: We created a retrospective, multinational registry of 524 patients who received a CF-LVAD (either HVAD or Heartmate II) between January 2008 and April 2017. Follow up spanned from date of CF-LVAD implant to post-HTx period with a median follow up of 44.8 months. Results: The cohort included 299 (57.1%) EU and 225 (42.9%) US patients. Although the US cohort was significantly older with a higher prevalence of comorbidities, survival was similar between the cohorts (US 63.1%, EU 68.4% at 5 years, unadjusted log-rank test p = 0.43).Multivariate analyses suggested that older age, higher body mass index, elevated creatinine, use of temporary mechanical circulatory support prior CF-LVAD, and implantation of HVAD were associated with increased mortality. Among CF-LVAD patients undergoing HTx, the median time on CF-LVAD support was shorter in the US, meanwhile US donors were younger. Finally, the pattern of adverse events (stroke, gastrointestinal bleedings, late right ventricular failure, and driveline infection) during support differed significantly between US and EU. Conclusions: Although waitlisted patients in the US on CF-LVAD have higher risk comorbid conditions, the overall outcome is similar in US and EU. Geographic variations with regards to donor characteristics, duration of CF-LVAD support prior to transplant, and adverse events on support can explain the disparity in the utilization of mechanical bridge to transplant strategy between US and EU.

- Background: Aortic stenosis (AS) is the most common valvular heart disease in developed countries, confers high mortality in advanced cases, but can effectively be reversed using endovascular or open-heart surgery. We evaluated the association between AS and neighborhood socioeconomic status (NSES). Methods: We used Swedish population-based nationwide registers and an echocardiography screening cohort during the study period 1997–2014. NSES was determined by an established neighborhood deprivation index composed of education, income, unemployment, and receipt of social welfare. Multilevel adjusted logistic regression models determined the association between NSES and incident AS (according to ICD-10 diagnostic codes). Results: The study population of men and women (n=6,641,905) was divided into individuals living in high (n = 1,608,815 [24%]), moderate (n = 3,857,367 [58%]) and low (n = 1,175,723 [18%]) SES neighborhoods. There were 63,227 AS cases in total. Low NSES (versus high) was associated with a slightly increased risk of AS (OR 1.06 [95% CI 1.03–1.08]) in the nationwide study population. In the echocardiography screening cohort (n = 1586), the association between low NSES and AS was markedly stronger (OR: 2.73 [1.05–7.12]). There were more previously undiagnosed AS cases in low compared to high SES neighborhoods (3.1% versus 1.0%). Conclusions: In this nationwide Swedish register study, low NSES was associated with a slightly increased risk of incident AS. However, the association was markedly stronger in the echocardiography screening cohort, which revealed an almost three-fold increase of AS among individuals living in low SES neighborhoods, possibly indicating an underdiagnosis of AS among these individuals.

- Aims: Peripheral artery disease (PAD) constitute a high-risk with adverse clinical outcomes. We aimed to investigate the cardiovascular outcomes following myocardial infarction (MI). Methods and results: This nationwide, Danish register-based follow-up study includes all patients experiencing an MI between 2000 and 2017. Patients with and without PAD were compared. Multivariable logistic regression was used to derive relative risks of 1-year major adverse cardiovascular events (MACE; all-cause mortality, reinfarction, stroke or heart failure). Individual components, cardiovascular mortality, and bleeding, standardized to age, sex and comorbidity distributions of all patients were assessed. MI patients with PAD (n = 5083, 2.9%) were older and more comorbid compared to patients without PAD (n = 174,673). After standardization, PAD was associated with higher 1-year relative risks of MACE (RR 1.21 [95% CI 1.17;1.25]), all-cause (RR 1.29 [95% CI 1.24;1.35]) and cardiovascular mortality (RR 1.3 [95% CI 1.24;1.36]), reinfarction (RR 1.17 [95% CI 1.11;1.22]), stroke (RR 1.12 [95% CI 0.92;1.32]), heart failure (RR 1.22 [95% CI 1.12;1.32]), and bleeding episodes (RR 1.25 [95% CI 1.04,1.46]). Similar results were seen in 30-day survivors after adjustment for antithrombotic post-discharge medication for MACE (RR 1.25 [95% CI 1.20,1.31]), all-cause mortality (RR 1.47 [95% CI 1.37,1.57], cardiovascular mortality (RR 1.49 [95% CI 1.37,1.61]), reinfarction (RR 1.17 [95% CI 1.08,1.12]) and heart failure (RR 1.22 [95% CI 1.12,1.32]). Conclusion: Comparing to patients without PAD, patients with PAD had increased 1-year relative risk of MACE, all-cause mortality, reinfarction, stroke, heart failure, cardiovascular mortality and bleeding following MI. The low prevalence of PAD is suggestive of considerable under-diagnosing.
