- BackgroundHeart failure is an established risk factor for poor outcomes in patients undergoing non-cardiac surgery, yet risk stratification remains a clinical challenge. We developed an index for 30-day mortality risk prediction in this particular group. Methods and resultsAll individuals with heart failure undergoing non-cardiac surgery between October 23 2004 and October 31 2011 were included from Danish administrative registers (n=16827). In total, 1787 (10.6%) died within 30days. In a simple risk score based on the variables from the revised cardiac risk index, plus age, gender, acute surgery, and body mass index category the following variables predicted mortality (points): male gender (1), age 56-65years (2), age 66-75years (4), age 76-85years (5), or age >85years (7), being underweight (4), normal weight (3), or overweight (1), undergoing acute surgery (5), undergoing high-risk procedures (intra-thoracic, intra-abdominal, or suprainguinal aortic) (3), having renal disease (1), cerebrovascular disease (1), and use of insulin (1). The c-statistic was 0.79 and calibration was good. Mortality risk ranged from <2% for a score <5 to >50% for a score 20. Internal validation by bootstrapping (1000 re-samples) provided c-statistic of 0.79. A more complex risk score based on stepwise logistic regression including 24 variables at P<0.05 performed only slightly better, c-statistic=0.81, but was limited in use by its complexity. ConclusionsFor patients with heart failure, this simple index can accurately identify those at low risk for perioperative mortality.

Journal article (peer-reviewed)abstract
- Background: Physical activity and appetite are important for maintaining physical health. Yet, sedentary lifestyle and poor appetite are frequently observed in the heart failure (HF) population. However, the relationships between these phenomena are not yet clearly understood. Purpose: To investigate the relationship between physical activity and appetite in patients with stable HF.Methods: In this cross sectional study, a consecutive sample of 186 patients with confirmed HF with NYHA class II-IV (median age 72y, 70% men, NYHA class II 61%) participated in the study. Patients were recruited from three HF outpatient clinics in central Sweden. Physical activity measures included total energy expenditure (TEE), active energy expenditure (AEE) above 3 METs, average daily METs and number of steps per day during four days using a validated multi-sensor wearable armband (SenseWear®, Body Monitoring System). Patients also self-reported their physical activity on a ten point numeric rating scale, from extremely low (1) to extremely high (10). Self-reported appetite was measured by Council on Nutrition Appetite Questionnaire (CNAQ), an 8-item instrument (score range 8-40) where CNAQ ≤28 indicate poor appetite. Associations between physical activity and appetite were analyzed by Spearman correlation while differences in physical activity between poor vs good appetite were analyzed using Mann Whitney U test.Results: There was a significant positive relationship between physical activity and appetite assessed by TEE (rs=.184, p=.012), AEE of moderate intensity >3 METs (rs=.262, p=.000), number of steps (rs=.292, p=.000), average METs intensity (rs=.249, p=.001), and self- reported physical activity (rs=.191, p =.009). Levels of physical activity in the low appetite group differed significantly from the group with better appetite, this was seen in all physical dimensions, TEE (U=3225, z=-2.26, p=.024), AEE (U=2902, z=-3.178, p=.001), number of steps (U=2706, z=-3.734, p=.000), average METs intensity (U=3128, z=-2.541, p=.011), levels of self-reported physical activity (U=3185, z=-2.47, p=.013).Conclusion: This study shows that physical activity is associated with appetite and that levels of physical activity differs between patients with poor and good appetite. These findings has implications for both research and practice and underlines the importance in monitoring both physical activity and appetite. Further research is needed to determine whether interventions targeting physical activity also improve appetite and vice versa in the HF population.

Rationale and design of Ferinject((R)) Assessment in patients with IRon deficiency and chronic Heart Failure (FAIR-HF) study: a randomized, placebo-controlled study of intravenous iron supplementation in patients with and without anaemia
- 2009

Journal article (peer-reviewed)abstract
- Iron deficiency (ID) and anaemia are common in patients with chronic heart failure (CHF). The presence of anaemia is associated with increased morbidity and mortality in CHF, and ID is a major reason for the development of anaemia. Preliminary studies using intravenous (i.v.) iron supplementation alone in patients with CHF and ID have shown improvements in symptom status. FAIR-HF (Clinical Trials.gov NCT00520780) was designed to determine the effect of i.v. iron repletion therapy using ferric carboxymaltose on self-reported patient global assessment (PGA) and New York Heart Association (NYHA) in patients with CHF and ID. This is a multi-centre, randomized, double-blind, placebo-controlled study recruiting ambulatory patients with symptomatic CHF with LVEF < 40% (NYHA II) or < 45% (NYHA III), ID [ferritin < 100 ng/mL or ferritin 100-300 ng/mL when transferrin saturation (TSAT) < 20%], and haemoglobin 9.5-13.5 g/dL. Patients were randomized in a 2:1 ratio to receive ferric carboxymaltose (Ferinject((R))) 200 mg iron i.v. or saline i.v. weekly until iron repletion (correction phase), then monthly until Week 24 (maintenance phase). Primary endpoints are (i) self-reported PGA at Week 24 and (ii) NYHA class at Week 24, adjusted for baseline NYHA class. This study will provide evidence on the efficacy and safety of iron repletion with ferric carboxymaltose in CHF patients with ID with and without anaemia.

LA diameter more than 40 mm predicts recurrence of atrial fibrillation after trans-catheter ablation : a systematic review and meta-analysis
- 2017

Journal article (peer-reviewed)abstract
- Background and Aim: Left atrial (LA) enlargement is associated with atrial fibrillation (AF) incidence and outcome. Trans-catheter ablation of AF has now become a conventional treatment of AF but its recurrence remains of clinical significance. The predictive role of the LA size in AF treatment is still controversial, hence the aim of this meta-analysis was to analyze the potential association between LA diameter and AF recurrence after ablation.Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar and the Cochrane Central Registry, up to December 2016 in order to select clinical trial and observational studies, which assessed the predictive role of LA diameter in AF recurrence after catheter-ablation. 13.573 patients from 61 studies with paroxysmal AF (PAF), persistent (PeAF) or longstanding persistent AF (L-PeAF) were included.Results: The pooled analysis showed that after a follow-up period of 19± 7.74 months, patients with AF recurrence had larger LA size compared with those without AF recurrence, with a weighted mean difference (WMD) 0.49 ([95% CI 0.39 to 0.59], P < 0.001), irrespective of the type of AF. A subgroup analysis showed LA diameter to be different; WMD was 2.29 ([95% CI 1.31 to 3.26], P < 0.001) in PAF and 1.51 ([95% CI 1.10 to 1.93], P < 0.001) in PeAF/L-PeAF, the difference between these two subgroups was not significant (Chi2=2.04, I2=51.1%, p=0.15). LA diameter ≥40 mm predicted AF recurrence HR:1.08 [95% CI 1.03 to 1.14], P=0.006), but the best cut-off value, in all included patients, was ≥50mm HR:2.73 [95% CI 1.64 to 4.55], P<0.001).Conclusions: Increased LA diameter significantly predicts recurrence of AF after ablation procedure. While a diameter of 40 mm predicts recurrence, a diameter more than 50 mm is the most accurate predictor.

Journal article (peer-reviewed)abstract
- Background and Aim: Despite the improved outcome of patients with atrial fibrillation (AF) who undergo catheter ablation, recurrence of the arrhythmia remains a concern. The aim of this meta-analysis was to assess the potential association between left atrial (LA) strain and AF recurrence after ablation.Methods: We systematically searched PubMed-Medline, EMBASE, Scopus, Google Scholar and the Cochrane Central Registry, up to December 2016 in order to identify clinical trial and observational studies, which assessed the predictive role of LA strain in AF recurrence after catheter-ablation. The search identified 898 patients form 10 studies, with paroxysmal AF (PAF) and persistent AF (PeAF).Results: The pooled analysis showed that after a follow-up period of 11.8± 8.1 months, patients with AF recurrence had reduced LA strain compared with those without AF, with a weighted mean difference (WMD) -7.04% ([95% CI -9.62 to -4.45], P < 0.0001). A subgroup analysis showed that LA strain was reduced regardless of AF type; WMD was -5.47% ([95% CI -9.82% to -1.13%], P=0.003) in PAF and -7.88% ([95% CI -11.19% to -4.56%], P < 0.001) in PAF/PeAF, the difference between these two subgroups was not significant (Chi2=0.75, I2=0.0%, p=0.39). A cut off value of 21% [6% to 30%], was 79% [65-86%] sensitive and 77% [66% to 91%] specific for predicting AF recurrence.Conclusions: Reduced LA strain significantly predicts recurrence of AF after ablation procedure, irrespective of AF type. This emphasizes the impact of LA wall remodeling on successful ablation.

Journal article (peer-reviewed)abstract
- Aims The prevalence and hospitalizations of patients with heart failure (HF) aged <55 years have increased in Sweden during the last decades. We aimed to compare characteristics of younger and older patients with HF, and examine survival in patients All patients >= 18 years in the Swedish Heart Failure Register from 2003 to 2014 were included. Data were merged with National Patient and Cause of Death Registers. Among 60 962 patients, 3752 (6.2%) were <55 years, and were compared with 7425 controls from the Population Register. Compared with patients >= 55 years, patients <55 years more frequently had registered diagnoses of obesity, dilated cardiomyopathy, congenital heart disease, and an ejection fraction <40% (9.8% vs. 4.7%, 27.2% vs. 5.5%, 3.7% vs. 0.8%, 67.9% vs. 45.1%, respectively; allP < 0.001). One-year all-cause mortality was 21.2%, 4.2%, and 0.3% in patients >= 55 years, patients <55 years, and controls <55 years, respectively (allP < 0.001). Patients <55 years had a five times higher mortality risk compared with controls [hazard ratio (HR) 5.48, 95% confidence interval (CI) 4.45-6.74]; the highest HR was in patients 18-34 years (HR 38.3, 95% CI 8.70-169; bothP < 0.001). At the age of 20, the estimated life-years lost was up to 36 years for 50% of patients, with declining estimates with increasing age. Conclusion Patients with HF <55 years had different comorbidities than patients >= 55 years. The highest mortality risk relative to that of controls was among the youngest patients.
