The aim of this review is to provide a practical approach for the assessment of patients presenting with STEMI and multivessel coronary artery disease by analysing randomised trials, meta-analyses and our clinical experience.

Therefore, the measurement of CAC is useful in guiding clinical decision-making for primary prevention (e.g. use of statin and aspirin). This tool has already been incorporated into the clinical guidelines and is steadily being integrated into standard clinical practice. The adoption of CAC scoring will be important for curbing the progressive burden that ASCVD is exerting on our healthcare system. It has already been projected that CAC testing will decrease healthcare spending and will hopefully be shown to improve ASCVD outcomes.

Typical DRESS features were absent at onset of these symptoms. Echocardiography demonstrated biventricular systolic dysfunction, and electrocardiography (ECG) showed complete right bundle branch block and diffuse ST-segment elevation.

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and intra-aortic balloon pump were initiated on the third day of admission. Endomyocardial biopsy suggested the diagnosis of DRESS-associated myocarditis and a high-dose corticosteroid was commenced.

After 24 days of ECMO support, the ventricular function improved, and ECG reverted to sinus rhythm.
