Neurogenic Stunned Myocardium

Öz

Neurogenic Stunned Myocardium (NSM) is a clinical condition that develops following neurological events and is accompanied by cardiac abnormalities. Studies in the literature suggest that autonomic nervous system dysregulation and increased catecholamine levels cause myocardial damage. NSM can be diagnostically challenging due to findings mimicking acute coronary syndrome, such as elevated troponin, left ventricular dysfunction, and electrocardiographic changes. Therefore, cardiac catheterization may be performed to rule out coronary artery disease. This study presents two cases diagnosed with NSM, aiming to increase awareness of the clinical features and diagnostic approach of the disease.

Nörojenik Sersemlemiş Miyokard (NSM)

Öz

Nörojenik Sersemlemiş Miyokard (NSM), nörolojik olaylara bağlı gelişen ve kardiyak anormalliklerle seyreden klinik bir durumdur. Literatürdeki çalışmalar; Otonom sinir sistemi disregülasyonu ve artmış katekolamin düzeylerinin miyokardiyal hasara yol açtığı düşünülmektedir. NSM, troponin yüksekliği, sol ventrikül disfonksiyonu ve elektrokardiyografik değişiklikler gibi akut koroner sendromu taklit eden bulgular nedeniyle tanısal açıdan zorluk oluşturabilir. Bu nedenle koroner arter hastalığını dışlamak amacıyla kardiyak kateterizasyon uygulanabilmektedir. Bu çalışmada, NSM tanısı alan iki olgu sunularak hastalığın klinik özellikleri ve tanısal yaklaşımına ilişkin farkındalığın artırılması amaçlanmıştır.
