What do Spanish registries report about worsening events in chronic heart failure? Needs and challenges

INTRODUCTION

Worsening heart failure (HF) is associated with a high risk of death and rehospitalization. Despite that, real world evidence about the impact of worsening HF on clinical practice is scarce.

AREAS COVERED

A narrative review about registries addressing recent worsening HF events in Spain, with special emphasis on patients recently hospitalized for HF was performed.

EXPERT OPINION

Worsening HF can be defined as situations where the patient's HF deteriorates to the extent that it necessitates initiation or intensification of diuretic treatment (mainly intravenous). The events can occur at the outpatient level, generally in the day hospital, in the emergency department or even hospitalization. Early identification of worsening HF events is essential to establish appropriate treatment as soon as possible. In this context, robust clinical benefits have been reported for renin-angiotensin system inhibitors, sacubitril-valsartan, beta-blockers, mineralocorticoid receptor antagonists, SGLT2 inhibitors, and vericiguat. In Spain, several registries of patients with HF have been developed, some of them including patients recently hospitalized for HF, but not with recent worsening HF events. Therefore, registries addressing recent worsening events would be desirable. Using a practical approach, this review analyzes the importance of worsening HF events, with special emphasis on Spanish data.

Influence of the medical treatment schedule in new diagnoses patients with heart failure and reduced ejection fraction

AIMS

Heart failure (HF) guidelines recommend treating all patients with HF and reduced ejection fraction (HFrEF) with quadruple therapy, although they do not establish how to start it. This study aimed to evaluate the implementation of these recommendations, analyzing the efficacy and safety of the different therapeutic schedules.

METHODS AND RESULTS

Prospective, observational, and multicenter registry that evaluated the treatment initiated in patients with newly diagnosed HFrEF and its evolution at 3 months. Clinical and analytical data were collected, as well as adverse reactions and events during follow-up. Five hundred and thirty-three patients were included, selecting four hundred and ninety-seven, aged 65.5 ± 12.9 years (72% male). The most frequent etiologies were ischemic (25.5%) and idiopathic (21.1%), with a left ventricular ejection fraction of 28.7 ± 7.4%. Quadruple therapy was started in 314 (63.2%) patients, triple in 120 (24.1%), and double in 63 (12.7%). Follow-up was 112 days [IQI 91; 154], with 10 (2%) patients dying. At 3 months, 78.5% had quadruple therapy (p < 0.001). There were no differences in achieving maximum doses or reducing or withdrawing drugs (< 6%) depending on the starting scheme. Twenty-seven (5.7%) patients had any emergency room visits or admission for HF, less frequent in those with quadruple therapy (p = 0.02).

CONCLUSION

It is possible to achieve quadruple therapy in patients with newly diagnosed HFrEF early. This strategy makes it possible to reduce admissions and visits to the emergency room for HF without associating a more significant reduction or withdrawal of drugs or significant difficulty in achieving the target doses.

Diagnosis and Management of Malnutrition in Patients with Heart Failure

Heart failure is a disease with an increasingly greater prevalence due to the aging population, the development of new drugs, and the organization of healthcare processes. Malnutrition has been identified as a poor prognostic factor in these patients, very often linked to frailty or to other comorbidities, meaning that early diagnosis and treatment are essential. This paper reviews some important aspects of the pathophysiology, detection, and management of malnutrition in patients with heart failure.

Optimizing the management of patients with worsening heart failure: beyond heart failure hospitalization

INTRODUCTION

Worsening heart failure (HF) is associated with a high risk of death and HF hospitalization.

AREAS COVERED

A systematic search was conducted on PubMed (MEDLINE), using the MeSH terms [Heart failure] + [Worsening] + [Treatment] + [Vulnerable period] up to February 2023. Original data from clinical trials, and observational studies were critically analyzed.

EXPERT OPINION

Although the vulnerable period has been traditionally limited to the first 6 months after HF hospitalization, the fact is that there are other clinical scenarios in which the patient is particularly vulnerable. These vulnerable patients may also include those that require parenteral administration of diuretics in the day hospital or emergency department, those in which the increase of oral diuretic dose in an outpatient setting is needed to relief congestive symptoms, as well as those that remain symptomatic despite treatment. On the other hand, HF is a complex disease in which different neurohormonal systems are involved. Therefore, to actually reduce the HF burden, a comprehensive management, targeting all the neurohormonal systems that are involved in the pathogenesis of HF, through the use of those drugs that have demonstrated to positively modify the clinical course of HF, is needed.

Identifying the patient with heart failure to be treated with vericiguat

The pathophysiology of heart failure with reduced ejection fraction (HFrEF) is a complex process in which a number of neurohormonal systems are involved. Targeting only some of these systems, but not all, translates into a partial benefit of HF treatment. The nitric oxide-soluble guanylate cyclase (sGC)-cGMP pathway is impaired in HF, leading to cardiac, vascular and renal disturbances. Vericiguat is a once-daily oral stimulator of sGC that restores this system. No other disease-modifying HF drugs act on this system. Despite guidelines recommendations, a substantial proportion of patients are not taking all recommended drugs or when taking them, they do so at low doses, limiting their potential benefits. In this context, treatment should be optimized considering different parameters, such as blood pressure, heart rate, renal function, or potassium, as they may interfere with their implementation at the recommended doses. The VICTORIA trial showed that adding vericiguat to standard therapy in patients with HFrEF significantly reduced the risk of cardiovascular death or HF hospitalization by 10% (NNT 24). Furthermore, vericiguat does not interfere with heart rate, renal function or potassium, making it particularly useful for improving the prognosis of patients with HFrEF in specific settings and clinical profiles.

Has the clinical profile of patients with nonvalvular atrial fibrillation treated with rivaroxaban changed in the last 5 years of use?

AIM

To analyze the evolution of clinical profile of patients with nonvalvular atrial fibrillation treated with rivaroxaban.

METHODS

Retrospective study in which patients treated with rivaroxaban were divided into two groups according to the data in which the initial prescription was performed (November 2012-December 2013 and January 2014-January 2017).

RESULTS

211 patients (mean age 76.7 ± 9.2 years; CHA₂DS₂-VASc 3.8 ± 1.5; HAS-BLED 2.0 ± 0.8.) were included. Age and bleeding risk were higher in those subjects in which the prescription started earlier. Rates of stroke/TIA, major bleeding and intracranial hemorrhage were 2.3/4.2/0.6 events/100 patient-years, respectively.

CONCLUSION

Although, the initial prescription of rivaroxaban was mainly performed in very elderly patients and/or with a higher bleeding risk, this has been extended to the overall nonvalvular atrial fibrillation population.
