Drug-induced heart failure

Drug-induced heart failure: a real-world pharmacovigilance study using the FDA adverse event reporting system database

Objective

Although there are certain drug categories associated with heart failure (HF), most of the associated risks are unclear. We investigated the top drugs associated with HF and acute HF (AHF) reported in the FDA Adverse Event Reporting System (FAERS).

Methods

We reviewed publicly available FAERS databases from 2004 to 2023. Using the search terms "cardiac failure" or "cardiac failure acute" and classifying cases by drug name, we processed and analyzed drug reports related to HF or AHF.

Results

From 2004 to 2023, 17,379,609 adverse drug events were reported by FAERS, of which 240,050 (1.38%) were reported as HF. Among those with HF, the male-to-female ratio was 0.94% and 52.37% were >65 years old; 46.2% were from the United States. There were 5,971 patients with AHF. We identified 38 drugs and 13 drug classes with a potential high risk of causing HF, and 41 drugs and 19 drug classes were associated with AHF. The median onset times of HF and AHF were 83 days (IQR: 11-416) and 49 days (IQR: 8-259), respectively. The Weibull shape parameter (WSP) test showed early failure-type profile characteristics.

Conclusion

This study highlights key drugs associated with drug-induced HF and AHF, emphasizing the importance of early risk assessment and close monitoring, particularly during the initial stages of treatment. These findings contribute to a better understanding of drug-induced HF and provide a basis for future research on its underlying mechanisms.

Emergency Department Use of Heart Failure-Exacerbating Medications in Patients with Chronic Heart Failure

BACKGROUND

Use of heart failure-exacerbating medications (HFEMs) may lead to preventable episodes of acute decompensated heart failure (HF). HFEMs use is common in patients with HF, and there may be opportunities to reduce their use from the emergency department (ED).

METHODS

We performed an observational study on patients with HF presenting to EDs within a healthcare system between 1 January 2016 and 31 December 2020. Patients with chronic HF were identified using diagnostic codes within the electronic health record. The cohort was restricted to ambulatory (i.e., discharged to home) ED encounters. Medications, either ordered in the ED or prescribed at ED discharge, were extracted from the medication administration record and identified as potential HFEMs based on the 2016 American Heart Association Scientific Statement. Descriptive statistics were used to summarize the prevalence of HFEM use during ambulatory ED encounters. Exploratory analyses to identify correlates of HFEM use were performed.

RESULTS

The study cohort included 23,907 ED encounters. ED administration or prescription of HFEMs occurred during 20% of ambulatory ED encounters. HFEM administration in the ED (17%) was more common than HFEM prescription at ED discharge (6%). The most common HFEMs administered in the ED included nonsteroidal anti-inflammatory drugs (11%) and albuterol (7%).

CONCLUSION

HFEM use is common in patients with HF seeking ED care, occurring in roughly one-fifth of ambulatory ED encounters. There may be opportunities to optimize medication use among patients with HF in the ED.

Incidence of heart failure following exposure to a protein kinase inhibitor, a French population-based study

AIMS

Pharmacovigilance signals of heart failure (HF) following exposure to protein kinase inhibitors (PKIs) have been detected in recent years. Our aim was to identify the PKIs most frequently associated with the development of HF.

METHODS

Using the French National Healthcare Database, all patients newly exposed to a PKI between January 2011 and June 2014 were followed up for 18 months. Specific hospitalization diagnosis and long-term HF-related disease codes were used to identify HF patients. HF incidence rate ratios (IRRs) were measured and adjusted hazard ratios (aHRs) were estimated using a Cox model. Sensitivity analyses were performed to limit the potential indication and competitive risk bias.

RESULTS

Thirteen PKIs were studied. Among the 49 714 new PKI users registered during the study period, the mean IRR of HF was 3.38 per 100 person-years, with a median time to onset of 155 days. We found a significant increase in the incidence of HF for six medicinal products: pazopanib (aHR = 2.42, 95% confidence interval [CI] 1.67-3.52), dasatinib (aHR = 2.22, 95% CI 1.42-3.44), ruxolitinib (aHR = 2.11, 95% CI 1.69-2.64), crizotinib (aHR = 1.71, 95% CI 1.07-2.72), everolimus (aHR = 1.45, 95% CI 1.26-1.67) and vemurafenib (aHR = 1.37, 95% CI 1.01-1.86). Sensitivity analyses were consistent with our primary analysis.

CONCLUSIONS

The current study provides knowledge on HF following exposure to a PKI. Additional studies could confirm these results for dasatinib, everolimus, pazopanib and ruxolitinib, and particularly for the two medicinal products with results slightly above the significance threshold, namely, crizotinib and vemurafenib, in our sensitivity analyses.

Parental transfer of an antibiotic mixture induces cardiotoxicity in early life-stage zebrafish: A cross-generational study

Antibiotic residues in the aquatic environment have been shown to induce significant adverse effects on the early-life stage development of aquatic organisms, though the underlying molecular mechanisms of these effects have not been well characterized. In this study, we performed global mRNA-miRNA sequencing, canonical pathway analyses, morphological, physiological, immunohistochemical, and behavioral analyses to comprehensively assess the cross-generational cardiotoxicity and mechanisms of antibiotic mixtures in zebrafish. Following parental treatment to 1 and 100 μg/L antibiotic mixtures (15 of the most commonly detected antibiotics) for 150 days, all 15 assessed antibiotics were detected in the F1 eggs, indicating the cross-generational transfer of antibiotics. Global mRNA-miRNA sequencing functional analysis predicted cardiotoxicity in the F1 generation by using the F1 whole fish. Consistent with canonical pathway analyses, significant cardiotoxicity was observed in F1 larvae, as well as the apoptosis of cardiac cells. Furthermore, let-7a-5p regulated the cardiac hypertrophy signaling pathway, suggesting mechanisms of miRNA of let-7 family mediating cross-generational cardiotoxicity of antibiotics in zebrafish. This study lays some groundwork for developing interventions to prevent parental exposure to environmental pollutants such as antibiotics from adversely affecting offspring development.

Potentially Inappropriate Prescriptions in Heart Failure with Reduced Ejection Fraction (PIP-HFrEF)

Heart failure (HF) is a chronic debilitating and potentially life-threatening condition. Heart Failure patients are usually at high risk of polypharmacy and consequently, potentially inappropriate prescribing leading to poor clinical outcomes. Based on the published literature, a comprehensive HF-specific prescribing review tool is compiled to avoid medications that may cause HF or harm HF patients and to optimize the prescribing practice of HF guideline-directed medical therapies. Recommendations are made in line with the last versions of ESC guidelines, ESC position papers, scientific evidence, and experts' opinions.

Substrates and potential therapeutics of ventricular arrhythmias in heart failure

Heart failure (HF) is a clinical syndrome characterized by ventricular contractile dysfunction. About 50% of death in patients with HF are due to fetal ventricular arrhythmias including ventricular tachycardia and ventricular fibrillation. Understanding ventricular arrhythmic substrates and discovering effective antiarrhythmic interventions are extremely important for improving the prognosis of patients with HF and reducing its mortality. In this review, we discussed ventricular arrhythmic substrates and current clinical therapeutics for ventricular arrhythmias in HF. Base on the fact that classic antiarrhythmic drugs have the limited efficacy, side effects, and proarrhythmic potentials, we also updated some therapeutic strategies for the development of potential new antiarrhythmic interventions for patients with HF.

ADVERPred-Web Service for Prediction of Adverse Effects of Drugs

Application of structure-activity relationships (SARs) for the prediction of adverse effects of drugs (ADEs) has been reported in many published studies. Training sets for the creation of SAR models are usually based on drug label information which allows for the generation of data sets for many hundreds of drugs. Since many ADEs may not be related to drug consumption, one of the main problems in such studies is the quality of data on drug-ADE pairs obtained from labels. The information on ADEs may be included in three sections of the drug labels: "Boxed warning," "Warnings and Precautions," and "Adverse reactions." The first two sections, especially Boxed warning, usually contain the most frequent and severe ADEs that have either known or probable relationships to drug consumption. Using this information, we have created manually curated data sets for the five most frequent and severe ADEs: myocardial infarction, arrhythmia, cardiac failure, severe hepatotoxicity, and nephrotoxicity, with more than 850 drugs on average for each effect. The corresponding SARs were built with PASS (Prediction of Activity Spectra for Substances) software and had balanced accuracy values of 0.74, 0.7, 0.77, 0.67, and 0.75, respectively. They were implemented in a freely available ADVERPred web service ( http://www.way2drug.com/adverpred/ ), which enables a user to predict five ADEs based on the structural formula of compound. This web service can be applied for estimation of the corresponding ADEs for hits and lead compounds at the early stages of drug discovery.

Tyrosine kinase-targeting drugs-associated heart failure

Background:

The impact of cancer therapies on cardiac disease in the general adult cancer survivor population is largely unknown. Our objective was to evaluate which tyrosine kinase-targeting drugs are associated with greater risk for new-onset heart failure (HF).

Methods:

A nested case–control analysis was conducted within a cohort of 27 992 patients of Clalit Health Services, newly treated with a tyrosine kinase-targeting, and/or chemotherapeutic drug, for a malignant disease, between 1 January 2005 and 31 December 2012. Each new case of HF was matched to up to 30 controls from the cohort on calendar year of cohort entry, age, gender, and duration of follow-up. Main outcome measure was odds ratio (OR) with 95% confidence interval (CI) of new-onset HF.

Results:

There were 936 incident cases of HF during 71 742 person-years of follow-up. Trastuzumab (OR 1.90, 95% CI 1.46–2.49), cetuximab (OR 1.72, 1.10–2.69), panitumumab (OR 3.01, 1.02–8.85), and sunitinib (OR 3.39, 1.78–6.47) were associated with increased HF risk. Comorbidity independently associated with higher risk in a multivariable conditional regression model was diabetes mellitus, hypertension, chronic renal failure, ischaemic heart disease, valvular heart disease, arrhythmia, and smoking.

Conclusions:

Trastuzumab, cetuximab, panitumumab, and sunitinib are associated with increased risk for new-onset HF.

Epidemiology of heart failure with preserved ejection fraction

Heart failure with preserved ejection fraction (HFPEF) is a common condition, and the prevalence is projected to increase further. Studies differ in the reported incidence and mortality associated with this condition, although there is agreement that between a third and one-half of all patients with heart failure have HFPEF. Although several consensus statements and guidelines have been published, some recent randomized clinical trials have reported low mortality, raising doubts about whether all patients diagnosed with HFPEF have HFPEF or whether the condition is heterogeneous in its cause and prognosis. The overall reported prognosis of patients with HFPEF remains poor.

VT-1161 dosed once daily or once weekly exhibits potent efficacy in treatment of dermatophytosis in a guinea pig model

Current therapies used to treat dermatophytoses such as onychomycosis are effective but display room for improvement in efficacy, safety, and convenience of dosing. We report here that the investigational agent VT-1161 displays potent in vitro antifungal activity against dermatophytes, with MIC values in the range of ≤0.016 to 0.5 μg/ml. In pharmacokinetic studies supporting testing in a guinea pig model of dermatophytosis, VT-1161 plasma concentrations following single oral doses were dose proportional and persisted at or above the MIC values for at least 48 h, indicating potential in vivo efficacy with once-daily and possibly once-weekly dosing. Subsequently, in a guinea pig dermatophytosis model utilizing Trichophyton mentagrophytes and at oral doses of 5, 10, or 25 mg/kg of body weight once daily or 70 mg/kg once weekly, VT-1161 was statistically superior to untreated controls in fungal burden reduction (P < 0.001) and improvement in clinical scores (P < 0.001). The efficacy profile of VT-1161 was equivalent to those for doses and regimens of itraconazole and terbinafine except that VT-1161 was superior to itraconazole when each drug was dosed once weekly (P < 0.05). VT-1161 was distributed into skin and hair, with plasma and tissue concentrations in all treatment and regimen groups ranging from 0.8 to 40 μg/ml (or μg/g), at or above the MIC against the isolate used in the model (0.5 μg/ml). These data strongly support the clinical development of VT-1161 for the oral treatment of onychomycosis using either once-daily or once-weekly dosing regimens.

[Diastolic heart failure: heart failure with preserved ejection fraction]

The prognosis for patients with diastolic heart failure--heart failure with preserved ejection fraction--has not improved in the last few decades despite improvement of prognosis for all patients with heart failure. Diastolic dysfunction is a typical finding in elderly patients with heart failure. The diagnostic process is a challenge for clinicians who are often faced with comorbidities like COPD, osteoarthritis, sarcopenia, and diabetes. Classical treatment options fail to improve patients with diastolic heart failure; thus, a comprehensive and specific treatment plan is necessary.

The comorbidity conundrum: a focus on the role of noncardiovascular chronic conditions in the heart failure patient

The rapid aging of the US population combined with improvements in modern medicine has created a new public health concern of comorbidity, a chronic condition that co-exists with a primary illness. Over 141 million Americans suffer from one or more comorbid conditions. In the heart failure (HF) patient, this comorbidity burden is particularly high, with over 40% of patients having five or more chronic conditions. These comorbidities can vary from being a risk factor to a cause of HF progression or even a precipitating factor for decompensation. Comorbidities, particularly the noncardiovascular conditions, have been associated with greater health resource utilization, poor health outcomes, and increased mortality. To minimize the negative impact that these comorbidities have on patient outcomes, appropriate attention should be paid to identifying, prioritizing, and managing each condition; minimizing medication complexity and polypharmacy; and improving overall coordination of care between providers and patients.
