Background: Shock, characterised by circulatory hypoperfusion and cellular hypoxia, represents a critical medical condition requiring immediate attention. Despite its significance, there are limited data on shock incidence and outcomes, particularly within the context of Thailand.
Objectives: This retrospective observational study aimed to investigate the incidence, management and outcomes of shock patients admitted to the internal medicine department of Siriraj Hospital, a referral university hospital in Bangkok, Thailand.

Aims: Cardiogenic shock remains a significant cause of mortality despite multiple advancements in medical interventions. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) provides crucial circulatory support but also increases left ventricular (LV) after-load, potentially worsening outcomes. Effective LV unloading strategies can enhance patient survival during VA-ECMO treatment.

Harlequin syndrome, also known as differential hypoxia (DH) or North-South syndrome, is a serious complication of femoro-femoral venoarterial extracorporeal membrane oxygenation (V-A ECMO). Moreover, Harlequin syndrome is caused by competing flows between the retrograde oxygenated ECMO output and the anterograde ejection of poorly oxygenated blood from the native heart. In the setting of impaired pulmonary gas exchange, the addition of an Impella device (ECPELLA configuration), although beneficial for ventricular unloading and hemodynamic support, may further exacerbate this competition and precipitate DH.

Rationale: Myocardial infarction with nonobstructive coronary arteries (MINOCA) has diverse ischemic etiologies and has been defined by the absence of angiographically significant obstructive coronary artery disease. Blood transfusion has seldom been reported as a precipitating factor for MINOCA. Here, we present a rare case of transfusion-associated MINOCA in a young woman without underlying chronic conditions, aiming to raise clinical awareness of this uncommon yet important phenomenon and to explore its potential pathophysiological mechanisms.
