Intravascular imaging (IVI), such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT), play a crucial role in assessing lesion characteristics and optimizing stent placement during percutaneous coronary intervention (PCI). Patients were divided into two groups based on IVI usage.

A formal ultrasound later showed reasonably good LV function, and so he later received carvedilol and diltiazem, Unfortunately, those led to hypotension at 80/40 with a HR 40. Several hours later, this was the effect: NT pro-BNP elevated to 7000 Furosemide was also given.

A b rief chart review revealed his most recent echo in 2018, with LV EF 67%, “very small” inferior wall motion abnormality. Pads were placed with ultrasound guidance, so they were in the correct position. Over past 3 months, he has had similar intermittent episodes of sharp chest pain while running, but none at rest.

This was a point of care ultrasound, not a bubble contrast echo.

A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW. The January 30, 2018 post — for PTA. Smith comment: this is diagnostic of OMI until proven otherwise. The September 22, 2019 post — intermittent ST-T wave artifact.

The ways to tell for certain include intravascular ultrasound (to look for extra-luminal plaque with rupture) or "optical coherence tomography," something I am entirely unfamiliar with. The authors recommend using optical coherence tomography or intravascular ultrasound imaging in patients with evidence of nonobstructive CAD by angiogram.
