Abstract

Objective: Atrial fibrillation is a common cardiac arrhythmia and is an important risk factor for ischemic stroke and heart failure. Thyroid hormones have important effects on the cardiovascular system. In this study, we aimed to evaluate the relationship between atrial fibrillation (AF) and thyroid disorders.
Materials and Methods: 587 newly diagnosed AF patients who applied to the Cardiology Clinic between January and December 2022 were included in this study. Thyroid function tests of the patients were examined.
Results: The mean age of the patients included in the study was 62.2 ± 9.8 years. 62% of the patients were female, and 38% were male. Euthyroid in 539 patients (91.7%), hypothyroidism in 2 patients (0.3%), subclinical hypothyroidism in 11 patients (2%), hyperthyroidism in 23 patients (3.9%), and subclinical hyperthyroidism in 12 patients (2.1%).
Conclusion: Atrial Fibrillation is associated with both hyperthyroidism and hypothyroidism. Thyroid dysfunctions are more common in patients with AF than in the normal population. Patients with AF should be screened for thyroid disorders.

Atrial Fibrilasyonu olan Hastalarda Tiroid Fonksiyon Bozukluğunun Değerlendirilmesi

Abstract

Amaç: Atriyal fibrilasyon yaygın bir kardiyak aritmidir ve iskemik inme ve kalp yetmezliği için önemli bir risk faktörüdür. Tiroid hormonlarının kardiyovasküler sistem üzerinde önemli etkileri vardır. Bu çalışmada atrial fibrilasyon (AF) ile tiroid bozuklukları arasındaki ilişkiyi değerlendirmek amaçlandı.
Materyal ve Metot: Bu çalışmaya Ocak – Aralık 2022 arasında Kardiyoloji Kliniğine başvuran yeni tanı almış 587 AF’li hasta alındı. Hastaların tiroid fonksiyon testleri incelendi.
Bulgular: Çalışmaya alınan hastaların yaş ortalaması 62.2 ± 9.8 idi. Hastaların %62’si kadın %38’i erkekti. 539 hasta ötiroid (%91,7), 2 hastada hipotiroidi (%0,3), 11 hastada subklinik hipotiroidi (%2), 23 hastada hipertiroidi (%3,9) ve 12 hastada subklinik hipertiroidi (%2,1) tespit edildi.
Sonuç: Atrial Fibrilasyon hem hipertiroidi ve hem hipotiroidi ile ilişkilidir. Tiroid fonksiyon bozuklukları AF’li hastalarda normal popülasyona göre daha sık görülür. AF’li hastalar tiroid bozuklukları açısından taranmalıdır.
