- Aims: This study is aimed at investigating the eligibility in a real-world heart failure population for the DAPA-HF (testing dapagliflozin) and EMPEROR-reduced (testing empagliflozin) trials, comparing the eligible real-world patients to trial participants and to characterize the noneligible patients.Methods: Medical records of all heart failure patients who had a diagnosis of heart failure from the Heart Centre or Department of Internal Medicine at Umea University Hospital were reviewed.Results: 2433 of the hospital's uptake population of 150 000 had a diagnosis of heart failure. 681 patients had left ventricle ejection fraction <= 40%, and of these 352 (52%) and 268 (39%) patients met eligibility criteria for DAPA-HF and EMPEROR-reduced, respectively. Comparing eligible patients in our population with the DAPA-HF- and EMPEROR-reduced trial populations, we found that eligible real-world patients were older (79.0 vs. 66.2 years and 80.3 vs. 67.2 years, respectively), had worse renal function (eGFR 54.4 vs. 66.0 ml/min/1.73m(2) and 49.5 vs. 61.8 ml/min/1.73m(2), respectively), higher prevalence of atrial fibrillation (56.0% vs. 36.1% and 53.0% vs. 35.6%, respectively), and lower prevalence of diabetes mellitus (21.0% vs. 41.8% and 26.1% vs. 49.8%, respectively). The main reasons for ineligibility were low NT-proBNP or low eGFR. Noneligible patients differed according to reason for ineligibility, where patients with low NT-proBNP were generally younger and healthier, and patients with low eGFR were older and had more comorbidities.Conclusions: 39-52% of patients with heart failure and reduced ejection fraction in this real-world heart failure population were eligible for SGLT2-inhibitor treatment, corresponding to 11-14% of all heart failure patients. Compared to trial participants, eligible real-world patients were significantly older with worse renal function, more atrial fibrillation, and less diabetes mellitus. Trial entry criteria exclude comparatively young and healthy patients, as well as comparatively old patients with more comorbid conditions.

- AIM: Previous studies and national assessments indicate an undertreatment of mineralocorticoid receptor antagonists (MRA) in heart failure with reduced ejection fraction (HFrEF). This study aimed to investigate why MRA is not used to full extent.METHODS: A complete community-based heart failure population was studied. Several variables were collected, and medical records were scrutinized to identify reasons for not prescribing MRA.RESULTS: Of 2029 patients, 812 had EF ≤40%. Five hundred and fifty-three patients (68%) tried MRA at some point but 184 of these (33%) discontinued therapy. There were 259 patients that never tried MRA with 177 with a listed explanation or contraindication. Eighty-two patients, 10% of the total HFrEF population, had no clear contraindications. They were older and had less HF hospitalizations compared to patients on MRA (P < 0.05) and 32% did not have any follow-up at the cardiology clinic. Contraindications to MRA were renal dysfunction (93 patients), hypotension (28 patients), and hyperkalemia (25 patients). Only six patients had hyperkalemia without renal dysfunction. Of the patients with renal dysfunction, 66 (72%) had eGFR >30 mL/min.CONCLUSIONS: The reasons why MRA are underutilized were mainly because of contraindications. However, the data suggest that physicians are overly cautious about moderately reduced kidney function. There seems to be a 10%-18% avoidable undertreatment with MRA, especially for elderly patients that are admitted to the hospital for other reasons than heart failure. This suggests that patients with heart failure would benefit from routine follow-up at a cardiology clinic.

- Aim. Sacubitril-valsartan has proven beneficial in heart failure with reduced ejection fraction. Guidelines recommend initiating half-dose sacubitril-valsartan before up-titration even to patients already on target dose angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARB). To reduce the number of titration steps needed in order to simplify for the patient as well as the clinic, we aimed to investigate the safety and tolerability of switching patients on target dose ACE inhibitors or ARBs directly to maximum-dose sacubitril-valsartan. Methods. This prospective cohort study was conducted between April 2016 and November 2017. A total of 66 patients with heart failure and reduced ejection fraction already on guideline-recommended target dose ACE inhibitors or ARBs (equivalent to enalapril 10 mg twice daily) were switched to maximum-dose sacubitril-valsartan (200 mg twice daily). The patients were followed for twelve months. Results. Patients had a mean age of 72 +/- 10 years, mean systolic blood pressure of 121 +/- 17 mmHg, and 92% were male. At 12-month follow-up, nine patients (14%) had discontinued sacubitril-valsartan, four patients (6%) had a dose reduction, and 17 patients (26%) had developed symptomatic hypotension. No angioedema occurred within the 12-month follow-up and there were no hospitalizations or emergency room visits within the first 14 days. Conclusions. Switching directly from target dose ACE inhibitors or ARBs to maximum-dose sacubitril-valsartan was safe and generally well tolerated.

- Background and AimWarfarin treatment discontinuation is significant among patients with atrial fibrillation (AF). Studies mainly focused on whether the proportion of warfarin persistence and discontinuationare clinically appropriate are absent. This study evaluates warfarin persistence with focus on predictors for, and reasons to, warfarin discontinuation in AF patients.MethodsFrom the national quality register AuriculA, all AF patients in Sundsvall, Sweden, on warfarin treatment on January first, 2010 were included. These 478 patients were followed until discontinuation or study-stop December 31, 2013. By going through each patient’s medical record risk factors for thromboembolism, bleeding and causes of discontinuation were obtained.ResultsProportion of warfarin persistence was 0.91 (95% confidence interval (CI) 0.89 to 0.93) after one year and 0.73 (95% CI 0.69 to 0.77) after four years. Previous intracranial bleeding, excessive alcohol use, anemia and pulmonary or peripheral emboli were each associated with over two times higher risk of discontinuation (hazard ratio (HR) 5.66, CI 2.23-14.36, HR 2.54, CI 1.48-4.37, HR 2.40, CI 1.38-4.17, and HR 2.13, CI 1.02-4.46). Among patients discontinuing, 50.5% were due to questionable causes, such as sinus rhythm (33.9%), patients demand (10.1%) and falls (8.2%). The majority (43.1%) of treatment discontinuers were changed to aspirin, while 40.4% of them were left without medical stroke prophylaxis.ConclusionsAlthough persistence to warfarin among AF patients proves higher than previously reported, there is room for improvement since half of the discontinuers have questionable reasons for treatment stop and the majority of them receive no other efficient stroke prophylaxis.

- ObjectiveOur primary objective was to determine the proportion of patients with atrial fibrillation (AF) eligible for enrollment in a randomized controlled trial for a novel oral anticoagulant, the ARISTOTLE trial. A secondary objective was to describe the reasons for trial ineligibility.MethodsWe performed a cross-sectional study of an unselected population including 2274 patients in Skelleftea, Sweden with at least one verified episode of AF on or before December 31, 2010. Patients were classified as suitable or unsuitable for anticoagulant treatment according to current guidelines. The enrollment criteria from the ARISTOTLE trial were extracted from the original publication and applied to the population.ResultsAmong all patients with AF, 1579 were classified as suitable for anticoagulant treatment. Of these, only 658 patients (42%) were eligible for participation in the ARISTOTLE trial. Among the 921 patients ineligible for participation, 498 did not meet the ECG criteria, 272 had psychosocial problems, and in addition, 78 patients were excluded due to both of these criteria.ConclusionOur study shows that a majority of the patients in an unselected population with AF suitable for anticoagulant treatment were ineligible for participation in the ARISTOTLE trial. The applicability of the ARISTOTLE trial is therefore unknown for a considerable proportion of patients with AF in real life.

Tidskriftsartikel (refereegranskat)abstract
- P>Background: Mode of death in chronic heart failure (CHF) may be of relevance to choice of therapy for this condition. Sudden death is particularly common in patients with early and/or mild/moderate CHF. beta-Blockade may provide better protection against sudden death than ACE inhibition (ACEI) in this setting. Methods: We randomized 1010 patients with mild or moderate, stable CHF and left ventricular ejection fraction < 35%, without ACEI, beta-blocker or angiotensin-receptor-blocker therapy, to either bisoprolol (n = 505) or enalapril (n = 505) for 6 months, followed by their combination for 6-24 months. The two strategies were blindly compared regarding adjudicated mode of death, including sudden death and progressive pump failure death. Results: During the monotherapy phase, 8 of 23 deaths in the bisoprolol-first group were sudden, compared to 16 of 32 in the enalapril-first group: hazard ratio (HR) for sudden death 0.50; 95% confidence interval (CI) 0.21-1.16; P = 0.107. At 1 year, 16 of 42 versus 29 of 60 deaths were sudden: HR 0.54; 95% CI 0.29-1.00; P = 0.049. At study end, 29 of 65 versus 34 of 73 deaths were sudden: HR 0.84; 95% CI 0.51-1.38; P = 0.487. Comparable figures for pump failure death were: monotherapy, 7 of 23 deaths versus 2 of 32: HR 3.43; 95% CI 0.71-16.53; P = 0.124, at 1 year, 13 of 42 versus 5 of 60: HR 2.57; 95% CI 0.92-7.20; P = 0.073, at study end, 17 of 65 versus 7 of 73: HR 2.39; 95% CI 0.99-5.75; P = 0.053. There were no significant between-group differences in any other fatal events. Conclusion: Initiating therapy with bisoprolol compared to enalapril decreased the risk of sudden death during the first year in this mild systolic CHF cohort. This was somewhat offset by an increase in pump failure deaths in the bisoprolol-first cohort.

Forskningsöversikt (refereegranskat)abstract
- BackgroundWarfarin is the most extensively used coumarin anticoagulant. It has been shown that the anticoagulant effect of warfarin is associated with genetic variation. Apolipoprotein E (ApoE) is a possible candidate to influence the maintenance dose of warfarin. ApoE affects the vitamin K cycle by mediating the uptake of vitamin K into the liver. The vitamin K cycle is the drug target of warfarin. However, the association between genetic variants of the APOE gene and warfarin dose requirement is still controversial. MethodsRevman 5.3 software was used to analyze the relationship between APOE genotypes and warfarin dose requirements. ResultsIn our meta-analysis, the E2/E2 genotype was significantly associated with warfarin dose. E2/E2 patients required 12% (P=0.0002) lower mean daily warfarin dose than E3/E3 carriers. In addition, subgroup analysis showed that Asians with the E4/E4 genotype tended to need lower warfarin maintenance doses, while the African American E4/E4 carriers needed slightly higher doses than E3/E3 carriers; however, these subgroups were very small. ConclusionThis is the first meta-analysis of the association between APOE genotypes and warfarin dose. APOE E2/E2 might be one of thefactors affecting warfarin dose requirements. The effect of APOE may vary between ethnicities.
