Post STEMI Echo Registry

This is a prospective observational study of consecutive patients presenting with STEMI to the Prince of Wales Hospital over a 12-month period. All patients will receive standard of care including reperfusion and GDMT irrespective of study enrolment. Patient will be followed for 9 months after enrolled in this study. Point-of-care ultrasound (POCUS) using a hand-held ultrasound (Vscan, GE Healthcare) will be performed to assess baseline LVEF within 48 hours of admission. Patients with baseline moderate-to-severe LV dysfunction by visual POCUS assessment (i.e. LVEF \<40%) will be recruited for follow-up LVEF assessment at 3 months. Patients with persistent LVEF \<40% by POCUS will undergo formal echocardiography to confirm LVEF by either 2D area (Simpson's rule) and 3D volumetric measurements. In 9 month visit, patient's clinical data will be collected and no echo is needed during this visit.
