The goal of this observational study is to learn how well Ferretab® comp. works and how safe it is for adults with iron deficiency anemia and cardiovascular disease who are receiving treatment as part of their usual medical care. The main questions it aims to answer are: * Does treatment with Ferretab® comp. improve anemia? * Does treatment with Ferretab® comp. improve heart-related symptoms, exercise tolerance, and overall well-being? * What side effects do participants have while taking Ferretab® comp.? This is a non-interventional study. Participants will receive Ferretab® comp. because their doctor has already decided to prescribe it as part of routine medical care. Ferretab® comp. is an oral medicine that contains iron (as iron fumarate) and folic acid. The study will not change their treatment. Participants will: * Take Ferretab® comp. for 12 weeks as prescribed by their doctor. * Attend study visits at the start of treatment, after about 4 weeks, and after about 12 weeks. * Have routine blood tests and health assessments during the study. * Report any side effects and record information in a patient diary. * Answer questions about their symptoms, exercise tolerance, and how easy the treatment is to use.
Iron deficiency anemia (IDA) is a common condition that may worsen symptoms and outcomes in people with cardiovascular diseases (CVDs). Adequate treatment of iron deficiency may improve hematologic parameters and reduce symptoms associated with anemia. This post-authorization, non-interventional study is designed to evaluate the effectiveness and safety of Ferretab® comp. in adults with IDA and concomitant cardiovascular disease treated under routine clinical practice conditions. As this is a non-interventional study, all diagnostic and therapeutic procedures will be performed in accordance with routine clinical practice and the approved Summary of Product Characteristics. No additional diagnostic or therapeutic procedures will be performed solely for study purposes. The study is intended to provide real-world evidence on the effectiveness, safety, and use of Ferretab® comp. in adults with iron deficiency anemia and concomitant cardiovascular disease treated in routine clinical practice. Composition of Ferretab® comp. Active ingredients: iron fumarate and folic acid. Each prolonged-release capsule contains 3 mini-tablets with iron fumarate and 1 mini-tablet with folic acid, which contain: iron fumarate equivalent to 50 mg of iron, folic acid - 500 mcg. Indications: Treatment of latent iron deficiency and iron deficiency anemia, combined with folic acid deficiency, including during pregnancy. Ferretab® comp. is registered in: Russia, Belarus, Kazakhstan, Kyrgyzstan, Armenia, Latvia, Lithuania, Romania, Austria, Uzbekistan
