Background: The management in primary care (PC) of the patients with Heart Failure (HF) is different from the management hospital, in a special way compared to cardiology departments. Objective: To define the characteristics in both phenotypes of HF in prevalent and incident cases of HF in patients recruited in a large PC sample. Methods: We proposed a and longitudinal analyses, in patients of the IBERICAN cohort, that recruited 8,066 patients in the Spanish primary care system, with 15,488 patients-years of follow-up. Of them, 252 patients (3.1%) had diagnoses of HF. HF was classified according to the 2014 guidelines in two groups: HF with a reduced eject fraction or HFrEF (LVEF < 50%) and HF with preserved eject fraction or HFpEF (LVEF ≥ 50%). Recommended treatment was defined as the patient receiving drug treatment with Renin-Angiotensin-System (RAS) blockers with beta-blockers and, optionally, spironolactone. The incidence of new cases of HF was calculated in the 7,814 patients without HF in the inclusion visit. Finally, we analysed which variables associated the onset new cases and get the hazard ratio (HR) with the confidence interval at 95% ([95%CI]). Clinical trials register: NCT02261441 (02/05/2017). Results: The HFpEF was the most frequent phenotype in prevalent cases (61.1%) and incident cases (73.9%). Patients with HFrEF had a higher prevalence of coronary heart disease (p = 0.008) and PAD (p = 0.028), and no statistically significant differences was observed in the therapeutic groups used between both groups. The incidence of HF was 12.8 cases/1000 inhabitants/year, 35.6% of them was diagnosed in PC. The renin-angiotensin system blockers were more used in PC (60%) and beta-blockers (100%) and spironolactone (60%) in hospital. The female sex showed a protective effect for incident cases (0.51 [0.28–0.92]); and AF (HR [95%CI]: 2.90 [1.51–5.54]), coronary heart disease (HR [95%CI]: 2.18 [1.19-4.00]) and hypertension (HR [95%CI]: 1.91 [1.00-3.64]) increased the risk of developing HF. Conclusions: HF phenotype more frequent and incident in PC was the HFpEF, but only one third of them are diagnosed in PC level. The female sex showed a protective effect and atrial fibrillation, ischaemic heart disease and hypertension increased the risk of develop HF. [ABSTRACT FROM AUTHOR]

Background This observational cohort study compared the likelihood of maintained (stabilized/up-titrated) renin–angiotensin–aldosterone system inhibitor (RAASi) therapy at 6 months following hyperkalaemia in patients with chronic kidney disease (CKD) and/or heart failure (HF) from the USA, Japan and Spain who received sodium zirconium cyclosilicate (SZC) for at least 120 days, relative to those with no prescription for a potassium (K+) binder. Methods Using health registers and hospital medical records, patients with CKD and/or HF receiving RAASi therapy who experienced a hyperkalaemia episode were identified. Propensity score (PS) matching (1:4) was applied to balance the SZC cohort to the no K+ binder cohort on baseline characteristics. Logistic regression analysis was performed to compare the odds of maintained RAASi therapy at 6 months in the SZC versus no K+ binder cohorts. Results The PS-matched SZC cohort included 565 (USA), 776 (Japan) and 56 (Spain) patients; the no K+ binder cohort included 2068, 2629 and 203 patients, respectively. At 6 months, 68.9% (USA), 79.9% (Japan) and 69.6% (Spain) in the SZC cohorts versus 53.1% (USA), 56.0% (Japan) and 48.3% (Spain) in the no K+ binder cohorts had maintained RAASi therapy. Meta-analysed across countries, the odds ratio of maintained RAASi therapy in the SZC cohort versus no K+ binder cohort was 2.56 (95% confidence interval 1.92–3.41; P  < .0001). Conclusions In routine clinical practice across three countries, patients treated with SZC were substantially more likely to maintain guideline-concordant RAASi therapy at 6 months following hyperkalaemia relative to patients with no K+ binder treatment.
