The VSR is what is causing the cardiogenic shock! It has been estimated that in the aggregate, they occur at a rate of about 3 per 1000 patients with acute MI, and most of these events occur in patients with STEMI. PIRP is strongly associated with myocardial rupture. PIRP was associated with persistent upright T waves.

Cardiogenic shock (CS)is the most feared event following STEMI. We tend to perceive CS as an exclusive complication of STEMI. The incidence is half of that of STEMI, i.e., 2.5-5%. might show little elevation with considerable overlap of left main STEMI vs NSTEMI ) 2.Onset How is CS in NSTEMI different ?

He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. At first glance, it seems the patient is having a STEMI. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock.

When the ST vector is primarily posterior, the diagnosis is usually posterior STEMI.
