Acute Coronary Syndrome in a Young Woman With Takayasu Arteritis and Pancoronary Aneurysms.

Background: Takayasu arteritis (TA) is a rare vasculitis affecting large vessels, predominantly in young women. Coronary artery involvement, although uncommon, significantly worsens the prognosis due to complications (eg, aneurysm formation, thrombosis), potentially leading to acute myocardial infarction.

Case Summary: A 27-year-old woman presented with fever, fatigue, and conjunctival erythema.

Hyponatraemia-induced Takotsubo syndrome secondary to idiopathic syndrome of inappropriate antidiuretic hormone: a case report.

Background: Takotsubo cardiomyopathy (TC), also known as stress cardiomyopathy or broken-heart syndrome, is an acute, reversible left ventricular dysfunction often triggered by stress and associated with elevated catecholamine levels. Hyponatraemia has been recognized as a potential trigger for TC, although its pathophysiological mechanisms remain unclear.

Case Summary: We present the case of an 84-year-old woman with a history of Type 2 diabetes, primary hypertension, hypothyroidism, and osteoporosis, who was admitted for typical angina and seizures.
