Unveiling the Heart of the Matter: Intravascular Ultrasound in Acute Myocardial Infarction.

Intravascular ultrasound (IVUS) has become crucial in contemporary percutaneous coronary interventions (PCIs), offering detailed two-dimensional (2D) arterial wall visualization. Current guidelines consider it valuable for guiding coronary stent placement, especially in complex cases like the left main (LM) artery, allowing a comprehensive assessment of vessel characteristics and stent performance. There are some studies that highlight the potential impact of IVUS on acute myocardial infarction (AMI) management, notably improving outcomes.

Myxedema Coma and the Heart: Would You Miss the Signs?

Myxedema Coma (MC) is a life-threatening medical emergency that occurs as a severe complication of untreated or poorly managed hypothyroidism. Prompt diagnosis is crucial as the condition can rapidly deteriorate and lead to life-threatening complications. Timely treatment of myxedema coma with intravenous levothyroxine is the cornerstone of treatment, along with glucocorticoids to support adrenal function.

Assembling the Puzzle: Taking into Account Clinical Presentation and Predictive Scores.

Syncope is a common cause of emergency department visits. Physicians must scrutinize for life-threatening causes to avoid patient morbidity and mortality. Clinical decision rules are used to stratify risks and guide the course of action, including the need for further testing.
