- We randomized 352 patients with suspected acute myocardial infarction (AMI) to treatment with rt-PA (n = 177) or placebo (n = 175). Patients were eligible if evaluated within 2 h and 45 min from onset of chest pain, and if aged less than 75 years. There were no ECG criteria for inclusion. A mobile coronary-care unit with a cardiologist present was used to initiate treatment at home in 29% of cases. During 1 year of follow-up the mortality in patients treated with rt-PA was 10.2%, as compared with 14.3% in patients the initial ECG, the mortality during the first year was 8% in the rt-PA group vs. 18% in the placebo group (P less than 0.05). Among patients without ST-elevation the mortality was 9% for the rt-PA group vs. 12% for the placebo group (NS). Requirement for rehospitalization, symptoms of angina pectoris and congestive heart failure, time of return to work and requirement for various medications did not differ significantly between the two groups, regardless of the initial ECG pattern.

- Growth hormone (GH) therapy in heart failure (HF) is controversial. We investigated the cardiovascular effects of GH in patients with chronic HF due to ischemic heart disease.In a double-blind, placebo-controlled trial, we randomly assigned 37 patients (mean age 66 years; 95% male) with ischemic HF (ejection fraction [EF] < 40%) to a 9-month treatment with either recombinant human GH (1.4 mg every other day) or placebo, with subsequent 3-month treatment-free follow-up. The primary outcome was change in left ventricular (LV) end-systolic volume measured by cardiac magnetic resonance (CMR). Secondary outcomes comprised changes in cardiac structure and EF. Prespecified tertiary outcomes included changes in New York Heat Association (NYHA) functional class and quality of life (QoL), as well as levels of insulin-like growth factor-1 (IGF-1) and N-terminal pro-brain natriuretic peptide (NT-proBNP).No changes in cardiac structure or systolic function were identified in either treatment group; nor did GH treatment affect QoL or functional class. In the GH group, circulating levels of IGF-1 doubled from baseline (+105%; p < 0.001) and NT-proBNP levels halved (-48%; p < 0.001) during the treatment period, with subsequently a partial return of both towards baseline levels. No changes in IGF-1 or NT-proBNP were observed in the placebo group at any time during the study.In patients with chronic ischemic HF, nine months of GH treatment was associated with significant increases in levels of IGF-1 and reductions in levels of NT-proBNP, but did not affect cardiac structure, systolic function or functional capacity.

- AimsEarly start and patient profile-oriented heart failure (HF) management has been recommended. In this post hoc analysis from the SHIFT trial, we analysed the treatment effects of ivabradine in HF patients with systolic blood pressure (SBP) < 110 mmHg, resting heart rate (RHR) & GE; 75 b.p.m., left ventricular ejection fraction (LVEF) & LE; 25%, New York Heart Association (NYHA) Class III/IV, and their combination. Methods and resultsThe SHIFT trial enrolled 6505 patients (LVEF & LE; 35% and RHR & GE; 70 b.p.m.), randomized to ivabradine or placebo on the background of guideline-defined standard care. Compared with placebo, ivabradine was associated with a similar relative risk reduction of the primary endpoint (cardiovascular death or HF hospitalization) in patients with SBP < 110 and & GE;110 mmHg [hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.74-1.08 vs. HR 0.80, 95% CI 0.72-0.89, P interaction = 0.34], LVEF & LE; 25% and >25% (HR 0.85, 95% CI 0.72-1.01 vs. HR 0.80, 95% CI 0.71-0.90, P interaction = 0.53), and NYHA III-IV and II (HR 0.83, 95% CI 0.74-0.94 vs. HR 0.81, 95% CI 0.69-0.94, P interaction = 0.79). The effect was more pronounced in patients with RHR & GE; 75 compared with <75 (HR 0.76, 95% CI 0.68-0.85 vs. HR 0.97, 95% CI 0.81-0.1.16, P interaction = 0.02). When combining these profiling parameters, treatment with ivabradine was also associated with risk reductions comparable with patients with low-risk profiles for the primary endpoint (relative risk reduction 29%), cardiovascular death (11%), HF death (49%), and HF hospitalization (38%; all P values for interaction: 0.40). No safety concerns were observed between study groups. ConclusionsOur analysis shows that RHR reduction with ivabradine is effective and improves clinical outcomes in HF patients across various risk indicators such as low SBP, high RHR, low LVEF, and high NYHA class to a similar extent and without safety concern.

- Aims The incidence and predictors of stroke in patients with heart failure and preserved ejection fraction (HF-PEF), but without atrial fibrillation (AF), are unknown. We described the incidence of stroke in HF-PEF patients with and without AF and predictors of stroke in those without AF. Methods and results We pooled data from the CHARM-Preserved and I-Preserve trials. Using Cox regression, we derived a model for stroke in patients without AF in this cohort and compared its performance with a published model in heart failure patients with reduced ejection fraction (HF-REF)-predictive variables: age, body mass index, New York Heart Association class, history of stroke, and insulin-treated diabetes. The two stroke models were compared and Kaplan-Meier curves for stroke estimated. The risk model was validated in a third HF-PEF trial. Of the 6701 patients, 4676 did not have AF. Stroke occurred in 124 (6.1%) with AF and in 171 (3.7%) without AF (rates 1.80 and 1.00 per 100 patient-years, respectively). There was no difference in performance of the stroke model derived in the HF-PEF cohort and the published HF-REF model (c-index 0.71, 95% confidence interval 0.57-0.84 vs. 0.73, 0.59-0.85, respectively) as the predictive variables overlapped. The model performed well in the validation cohort (0.86, 0.62-0.99). The rate of stroke in patients in the upper third of risk approximated to that in patients with AF (1.60 and 1.80 per 100 patient-years, respectively). Conclusions A small number of clinical variables identify a subset of patients with HF-PEF, but without AF, at elevated risk of stroke.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: We explored the impact of having a hospital admission for an acute coronary syndrome (ACS) on the subsequent prognosis among patients with chronic heart failure (CHF). METHODS AND RESULTS: A total of 7599 patients with CHF, New York Heart Association Classes II-IV, were randomly assigned to candesartan or placebo. We assessed the risk of death after a first ACS using time-updated Cox proportional hazard models adjusted for baseline predictors. During a mean follow-up of 3.3 years, 1174 patients experienced at least one ACS. Myocardial infarction (MI) was the first ACS in 442 subjects and unstable angina (UA) in 732. After these events, 219 (49.5%) and 167 (22.8%) patients died during follow-up. The early risk of death was more pronounced after MI: 30.2% died within 30 days compared with 3.6% after UA. After an ACS event, the risk of death declined steadily over time, although 18 months after an MI the risk was still twice that of patients without an ACS. CONCLUSION: Patients with CHF, who develop an ACS, have markedly increased subsequent mortality, particularly in the early phase after an MI.

Aim: To evaluate the effects of PCC in the form of structured telephone support on self-reported cardiac self-efficacy in patients with COPD. Methods: We enrolled 105 patients, aged ≥50 years, admitted to hospital and diagnosed with COPD from January 2015 to November 2016. The patients received usual care or PCC via telephone added to usual care. The Swedish Cardiac Self-Efficacy Scale comprising three dimensions (control symptoms, control illness and maintain functioning) was used as outcome measure. Data was collected at baseline, and at 3- and 6-month follow-ups. Results: At both the 3- and 6-month follow-ups, the intervention group improved significantly more than the control group in the control illness dimension (p =.012 and p =.032, respectively). No differences were found in the other two dimensions. Conclusions: PCC in the form of structured telephone support increases patients’ confidence in managing their illness and may be a feasible strategy to support patients in their homes.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: A core feature of chronic obstructive pulmonary disorder (COPD) and chronic heart failure (CHF) is that symptoms may change rapidly because of illness progression. Thus, these chronic conditions are associated with high rehospitalisation rates. Person-centred care (PCC) has been shown to have several benefits for patients with COPD or CHF (or both disorders) but it has not yet been investigated through e-health services. AIM: The project aims to evaluate the effects of PCC by a combined digital platform and structured telephone support for people with COPD and/or CHF. METHODS AND ANALYSIS: A randomised controlled trial with open, parallel groups which employs a participatory design process will be used. This project will also include process and health economic evaluation of the intervention. ETHICS AND DISSEMINATION: Ethical approval has been secured from the Regional Ethical Review Board in Gothenburg, Sweden (Dnr 063-17 and T063-18). Results will be presented at conferences and to healthcare professionals, participants and patient organisations. Findings will also be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT03183817.
