Management of hyperkalaemia in acute kidney injury in a heart failure patient with patiromer

Aims: One prevalent comorbidity of chronic heart failure (CHF) is chronic kidney disease(CKD). Hyperkalemia is associated with both CHF and CKD, which often leads to withdrawal of heart failure medications in clinical praxis. Methods and results: A patient is presented who suffered from acute kidney injury with pre‐existing CKD as heart failure comorbidity and a history of hyperkalemia. Conclusions: This case shows that potassium levels remained stable in acute kidney injury under ongoing heart failure medications, including an MRA, with the use of the potassium binder patiromer

ATENDIMENTO DOS PARÂMETROS LEGAIS DA EDUCAÇÃO AMBIENTAL NAS ESCOLAS DE EDUCAÇÃO BÁSICA DO MUNICÍPIO DE TUBARÃO, NA ÓTICA DOS SEUS DIRIGENTES

A pesquisa objetivou avaliar o atendimento dos parâmetros legais nacionais e internacionais da Educação Ambiental nas escolas de Educação Básica do Município de Tubarão. Com pesquisa bibliográfica, documental e entrevista, verificou-se que a maioria das escolas está em sintonia com as linhas de atuação da PNEA e desenvolvem a EA como uma prática educativa integrada, contínua e permanente em todos os níveis e modalidades do ensino formal. A legislação não é diretamente trabalhada na maioria das escolas, mas as práticas educativas destas atendem aos parâmetros normativos constantes em Diretrizes e Pareceres do MEC. Mesmo sem a consciência, as escolas dão cumprimento aos conteúdos de normas e documentos internacionais da área ambiental. O estímulo dos estudantes para os temas da EA ocorre por métodos tradicionais (aulas e trabalhos expositivos) e por uma diversidade de projetos de aprendizagem, transbordando o ambiente escolar e envolvendo públicos externos. A percepção dos dirigentes quanto ao interesse dos estudantes sobre a EA é mediano (63%) e alto (37%)

Heart-Focused Anxiety, General Anxiety, Depression and Health-Related Quality of Life in Patients with Atrial Fibrillation Undergoing Pulmonary Vein Isolation

(1) Background: Atrial fibrillation (AF) is associated with anxiety, depression, and chronic stress, and vice versa. The purpose of this study was to evaluate potential effects of pulmonary vein isolation (PVI) on psychological factors. (2) Methods: Psychological assessment was performed before PVI as well as after six months. (3) Results: A total of 118 patients [age 64 ± 9 years, 69% male, left ventricular ejection fraction 57 ± 8%, 56% paroxysmal AF] undergoing PVI were included. After PVI, significant improvements were observed in the mean total heart-focused anxiety (HFA) score, as well as in the Cardiac Anxiety Questionnaire (CAQ) sub-scores: HFA attention, HFA fear, and HFA avoidance scores. Subgroup analyses showed an association of improvement with freedom of documented AF recurrence. Mean scores of general anxiety and depression evaluated by the Hospital Anxiety and Depression Scale (HADS) decreased significantly after PVI in all subgroups regardless of AF recurrence. Further, both physical and mental composite scores of the Short Form Health Survey (SF-12) increased significantly from baseline. (4) Conclusions: PVI results in a significant reduction in HFA. Improvements in general anxiety and depressive symptoms did not seem to be related only to rhythm control per se. Therefore, CAQ may represent a more specific evaluation tool as HADS in patients with AF

Changes in quality of life, depression, general anxiety, and heart-focused anxiety after defibrillator implantation

Aims The Anxiety-CHF (Anxiety in patients with Chronic Heart Failure) study investigated heart-focused anxiety (HFA, with the dimensions fear, attention, and avoidance of physical activity), general anxiety, depression, and quality of life (QoL) in patients with heart failure. Psychological measures were assessed before and up to 2 years after the implantation of an implantable cardioverter defibrillator (ICD) with or without cardiac resynchronization therapy defibrillator (CRT-D). Methods and results One hundred thirty-two patients were enrolled in this monocentric prospective study (44/88 CRT-D/ICD, mean age 61 ± 14 years, mean left ventricular ejection fraction 31 ± 9%, and 29% women). Psychological assessment was performed before device implantation as well as after 5, 12, and 24 months. After device implantation, mean total HFA, HFA-fear, HFA-attention, general anxiety, and QoL improved significantly. Depression and HFA-related avoidance of physical activity did not change. CRT-D patients compared with ICD recipients and women compared with men reported worse QoL at baseline. Younger patients (<median of 63 years) had higher levels of general anxiety and lower levels of HFA-avoidance at baseline than older patients. After 24 months, groups no longer differed from each other on these scores. Patients with a history of shock or anti-tachycardia pacing (shock/ATP; N = 19) reported no improvements in psychological measures and had significantly higher total HFA and HFA-avoidance levels after 2 years than participants without shock/ATP. Conclusions Anxiety and QoL improved after device implantation, and depression and HFA-avoidance remained unchanged. HFA may be more pronounced after shock/ATP. Psychological counselling in these patients to reduce HFA and increase physical activity should be considered

Sacubitril/valsartan in heart failure : efficacy and safety in and outside clinical trials

Heart failure (HF) treatment has changed substantially over the last 30 years, leading to significant reductions in mortality and hospital admissions in patients with HF with reduced ejection fraction (HFrEF). Currently, the optimization of guideline-directed chronic HF therapy remains the mainstay to further improve quality of life, mortality, and HF hospitalizations for patients with HFrEF. The angiotensin receptor-neprilysin inhibitor sacubitril/valsartan (S/V) has an important role in the treatment of patients with HFrEF. The PARADIGM-HF (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) randomized controlled trial has established solid evidence for the treatment of HFrEF in various subgroups. Apart from HFrEF, several studies have been conducted using S/V in various indications: patients hospitalized with acute decompensated HF, HF with preserved ejection fraction, acute myocardial infarction with reduced ejection fraction, uncontrolled and resistant hypertension, and chronic kidney disease. Data from the German Institute for Drug Use Evaluation reveal that implementation of S/V has increased steadily over time and, by the end of 2021, an estimated 266 000 patients were treated with S/V in Germany. The estimated cumulative real-world patient exposure is >5.5 million patient-treatment years worldwide. The number of patients treated with S/V largely exceeds the number of patients treated in clinical trials, and the current indication for S/V is larger than the strict inclusion/exclusion criteria of the randomized trials. Especially elderly patients, women, and patients with more and more severe comorbidities are underrepresented in the clinical trials. We therefore aimed to summarize the importance of S/V in HF in terms of efficacy and safety in clinical trials and daily clinical practice

Timely and individualized heart failure management: need for implementation into the new guidelines

Due to remarkable improvements in heart failure (HF) management over the last 30 years, a significant reduction in mortality and hospitalization rates in HF patients with reduced ejection fraction (HFrEF) has been observed. Currently, the optimization of guideline-directed chronic HF therapy remains the mainstay to further improve outcomes for patients with HFrEF to reduce mortality and HF hospitalization. This includes established device therapies, such as implantable defibrillators and cardiac resynchronization therapies, which improved patients' symptoms and prognosis. Over the last 10 years, new HF drugs have merged targeting various pathways, such as those that simultaneously suppress the renin–angiotensin–aldosterone system and the breakdown of endogenous natriuretic peptides (e.g., sacubitril/valsartan), and those that inhibit the If channel and, thus, reduce heart rate (e.g., ivabradine). Furthermore, the treatment of patient comorbidities (e.g., iron deficiency) has shown to improve functional capacity and to reduce hospitalization rates, when added to standard therapy. More recently, other potential treatment mechanisms have been explored, such as the sodium/glucose co-transporter inhibitors, the guanylate cyclase stimulators and the cardiac myosin activators. In this review, we summarize the novel developments in HFrEF pharmacological and device therapy and discuss their implementation strategies into practice to further improve outcomes

Adherence to Antihypertensive Drugs Assessed by Hyphenated High-Resolution Mass Spectrometry Analysis of Oral Fluids

Background It is currently unknown if antihypertensive drugs can be monitored in oral fluid (OF) using liquid chromatography coupled to high-resolution mass spectrometry. Methods and Results We assessed adherence using liquid chromatography coupled to high-resolution mass spectrometry in OF, plasma, and urine of 56 consecutive patients with hypertension referred to a tertiary hypertension unit. Of these patients, 59% were completely adherent (all drugs detectable in urine), whereas 29% and 13% were partially adherent (1 drug not detectable in urine) or nonadherent (>1 drug not detectable in urine), respectively. Adherent patients were on fewer antihypertensive drugs (P=0.001), had fewer daily drug doses (P=0.012), and had lower 24-hour ambulatory systolic (P=0.012) and diastolic (P=0.009) blood pressures than nonadherent or partially adherent patients. Most drugs were detected in urine compared with plasma and OF (181 versus 119 versus 88; P=0.001). Compared with urine and plasma, detection rates of angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and diuretics were lower in OF. There was no difference in the frequency of detecting β blockers (P=1.0) and calcium channel blockers (P=0.063) when comparing OF with urine. There was no difference in the number of calcium channel blockers (P=0.727), β blockers (P=1.000), thiazide diuretics (P=0.125), and α-2 agonists (P=0.125) identified between OF and plasma. Conclusions This study shows the feasibility of drug adherence testing for several antihypertensive drugs, especially those without acidic components, in OF, with a similar recovery compared with plasma. Therefore, drug adherence testing in OF should be further explored as a noninvasive approach, which can easily be performed in an "out-of-office" setting

Therapeutic approaches in heart failure with preserved ejection fraction: past, present, and future

In contrast to the wealth of proven therapies for heart failure with reduced ejection fraction (HFrEF), therapeutic efforts in the past have failed to improve outcomes in heart failure with preserved ejection fraction (HFpEF). Moreover, to this day, diagnosis of HFpEF remains controversial. However, there is growing appreciation that HFpEF represents a heterogeneous syndrome with various phenotypes and comorbidities which are hardly to differentiate solely by LVEF and might benefit from individually tailored approaches. These hypotheses are supported by the recently presented PARAGON-HF trial. Although treatment with LCZ696 did not result in a significantly lower rate of total hospitalizations for heart failure and death from cardiovascular causes among HFpEF patients, subanalyses suggest beneficial effects in female patients and those with an LVEF between 45 and 57%. In the future, prospective randomized trials should focus on dedicated, well-defined subgroups based on various information such as clinical characteristics, biomarker levels, and imaging modalities. These could clarify the role of LCZ696 in selected individuals. Furthermore, sodium-glucose cotransporter-2 inhibitors have just proven efficient in HFrEF patients and are currently also studied in large prospective clinical trials enrolling HFpEF patients. In addition, several novel disease-modifying drugs that pursue different strategies such as targeting cardiac inflammation and fibrosis have delivered preliminary optimistic results and are subject of further research. Moreover, innovative device therapies may enhance management of HFpEF, but need prospective adequately powered clinical trials to confirm safety and efficacy regarding clinical outcomes. This review highlights the past, present, and future therapeutic approaches in HFpEF
