Thyroid hormone metabolic disarray has been identified as a risk factor for the progression of heart disease and the development of heart failure (HF). Both hyper- and hypothyroidism have been associated with a failing myocardium. Poor cardiac contractility and low cardiac output due to hyperthyroidism is a rare occurrence and is mostly seen in patients with preexisting heart disease. Referred to as a "rate related" phenomenon, hyperthyroid-induced sustained sinus tachycardia or atrial fibrillation may further reduce ventricular contractility. Increasingly, the hypothyroid state, and in particular a low triiodothyronine level, has been associated with a reduced cardiac performance and poor prognosis in HF, even in the presence of normal thyroid-stimulating hormone levels. Low thyroid hormone levels alter cardiac gene expression and increase systemic vascular resistance, both resulting in a reduction of cardiac contractility and cardiac output. This review summarizes current data on thyroid dysfunction and HF as well as the emerging implications of the "low triiodothyronine state."

Background As part of the risk-management plan for aflibercept in the European Union, materials have been developed to educate physicians and patients in Europe on the safe use of aflibercept. Objectives The objectives of this study were to measure receipt of the educational materials and to evaluate understanding of key safety information for aflibercept. Methods An observational cross-sectional study among physicians and patients with recent aflibercept experience in France, Germany, Italy, Spain, and the UK was conducted. Eligible physicians and patients completed a brief questionnaire regarding their knowledge of key safety information. Results Among the 8424 physicians invited to participate in the survey, 428 physicians were eligible, completed the questionnaire, and were included in this analysis. Most physicians reported having received the aflibercept summary of product characteristics (87%) and prescriber guide (77%); approximately half reported receiving the injection procedure video (50%) and patient booklet (54%). Physician knowledge of the most important topics (i.e., side effects; preparing patients for aflibercept injection) was high. Physician knowledge of dosing was high for neovascular (wet) age-related macular degeneration and lower for less commonly prescribed indications. Most physicians knew the contraindications for aflibercept and recognized possible side effects. Among the 874 patients approached about participation in the study, 773 patients were eligible, completed the questionnaire, and were included in the analysis. Patients' reported receipt was relatively low for the aflibercept patient booklet (38%) and the audio CD (23%). Patient knowledge of the health conditions to discuss with a doctor prior to injection was generally high; knowledge about possible side effects varied. Most patients knew that they should speak to a physician immediately if they experienced a possible side effect of aflibercept. Conclusion Most physicians reported receiving the summary of product characteristics, prescriber guide, and patient booklet; half reported receiving the intravitreal injection procedure video. Patient receipt of the educational material was variable. Observed patterns of knowledge indicated the greatest knowledge of the most important risks emphasized in the educational material and lower knowledge of more complex or less salient aspects of safe use.

Purpose To determine the reported rates of intraocular inflammation (IOI) in patients treated with intravitreal aflibercept (IVT-AFL) 2 mg in routine clinical practice (ie, outside interventional studies), across all indications and within all countries (excluding the United States), with access to either the vial presentation or pre-filled syringe (PFS). Patients and methods A search was conducted using the Bayer EYLEA ® Global Safety Pharmacovigilance Database for reported cases of IOI and IVT-AFL use between October 2012 and March 31, 2022. Results With more than 10 years of post-marketing experience with the IVT-AFL vial presentation (>25 million sold units), and over 2 years of experience with the PFS of IVT-AFL (>6.7 million sold units) the rate of any IOI, including endophthalmitis, outside the United States was 0.3 events per 10,000 units for the PFS and 1.2 events per 10,000 units for the vial presentation. The event rates specifically for endophthalmitis were 0.1 per 10,000 units for the IVT-AFL PFS and 0.6 per 10,000 units for the IVT-AFL vial presentation. Conclusion In patients with retinal diseases treated in routine clinical practice with IVT-AFL either from a vial or the PFS, medically important adverse events of IOI, and in particular, endophthalmitis, are infrequently reported events. Numerically, reported rates of IOI and endophthalmitis are low for the vial presentation and even lower for the PFS.
