Objectives To ascertain whether invasive assessment of coronary physiology soon after recanalisation of the culprit artery by primary percutaneous coronary intervention is associated with the development of microvascular obstruction by cardiac magnetic resonance in patients with ST-segment elevation myocardial infarction (STEMI).

This has important clinical significance , as many successfully lysed STEMI patient might have minimal segments of dissection/deep plaque fissures. , Spontaneous coronary dissection vs Iatrogenic dissection SCAD is a rare , different entity , enjoys a popular space in the patho-physiology of CAD. Is plaque fissure painful ?

In contrast — it is EASY to overlook L A- L L reversal — because the ECG picture seen with this type of lead reversal does not immediately stand out as physiologically “off”. P utting I t A ll T ogether : After correcting for LA-LL lead reversal — ECG # 1a shows sinus rhythm — LVH — and an acute infero-postero STEMI with acute RV involvement.

Frailty is a syndrome of physiological decline, characterized by marked vulnerability to adverse health outcomes. Frailty and CVD are often interrelated, affecting disease and treatment outcomes. Frailty is prevalent in adults with IHD requiring PCI.

Here, I do not see OMI (although the ECG is falsely STEMI positive with just over 1 mm STE in V1 and about 2.5 The atrial rate is around 120 beats per minute, which indicates high adrenergic state and physiologic distress!

It was read by the treating physician and the overreading cardiologist as "Paced, no STEMI." As the troponin T was 1521 ng/L (peak troponin T over 1000 ng/L is typical of STEMI) and still rising, no further troponins were measured. How does the Queen of Hearts do? For clarity in Figure-1 — I’ve labeled the initial ECG in today’s case.
