Dynamic OMI ECG. Negative trops and negative angiogram does not rule out coronary ischemia or ACS.

Dr. Smith's ECG Blog

This confirms that the pain was ischemia and is now resovled. Thus, it has recently become generally accepted that most plaque ruptures resulting in myocardial infarction occur in plaques that narrow the lumen diameter by 40% of the arterial cross section may be involved by plaque. The i nitial hs troponin I returned 75%.

Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead. Type I ischemia. He was taken to the Cath Lab.

An undergraduate who is an EKG tech sees something. The computer calls it completely normal. How about the physicians?

Dr. Smith's ECG Blog

This EKG is diagnostic of transmural ischemia of the inferior wall. The scan also showed “scattered coronary artery plaques”. __ Smith comment 1 : the appropriate management at this point is to lower the blood pressure (lower afterload, which increases myocardial oxygen demand). Lead I also shows reciprocal ST depression.

HeartFlow Announces Revolutionary Five-Year Data Demonstrating a 63 Percent Mortality Reduction with FFRCT-Guided Care in PAD Patients

DAIC

6 This novel study marks a significant milestone in the field, evaluating the effectiveness of FFR CT in detecting ischemia-producing coronary stenosis in patients with severe PAD. Diagnosis and treatment of ischemia-producing coronary stenoses improves 5-year survival of patients undergoing major vascular surgery.”

What does the angiogram show? The Echo? The CT coronary angiogram? How do you explain this?

Dr. Smith's ECG Blog

This suggests further severe ischemia. MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection; myocardial disorders, including myocarditis, takotsubo cardiomyopathy, and other cardiomyopathies. And yet the arteries remain open.

Intravascular Ultrasound (IVUS) for Coronary Intervention

All About Cardiovascular System and Disorders

IVUS Measurements Measurements include the measurement of lumen, plaque, calcium, remodeling, stent length and volumetric measurements. Plaque morphology assessment with IVUS Plaque morphology can be assessed in terms of its geometry and echogenicity. A vulnerable plaque and a plaque with ulceration or rupture can also be found.
