Chest Pain, ST Elevation, and an Elevated Troponin: Should we Activate the Cath Lab?

Dr. Smith's ECG Blog

She is somewhat hypertensive, but her vital signs are otherwise normal. However, old MI w/aneurysm morphology (persistent ST-Elevation) can look just like this. While this may be change that is reciprocal to an Acute/Subacute Inferior STEMI, the problem is that LV aneurysm may also manifest with this reciprocal change.

Abstract TP247: Iatrogenic Cervical Artery Dissections during Endovascular Interventions

Stroke Journal

Common comorbidities included hypertension (62.5%), smoking (56.3%), and hyperlipidemia (46.9%). Of the 32 patients, 9(28.1%) had dissection with diagnostic angiograms, 6(18.8%) endovascular thrombectomy, 15(46.9%) aneurysm treatment, and 2(6.3%) angioplasty with or without stenting.

LVH with anterior ST Elevation. When is it anterior STEMI?

Dr. Smith's ECG Blog

Her vitals signs were remarkable for marked hypertension. However, the ST segments in patients with LVH may show significant variation over time in the absence of ischemia. 3 Some have also suggested that the typically asymmetric T wave inversion (TWI) of LVH might be distinguished from the typically symmetric TWI of cardiac ischemia.

Compare these two ECGs. Do either, neither, or both show anything important?

Dr. Smith's ECG Blog

He was mildly tachycardic (105-110 bpm) and hypertensive (157/92 mm Hg) on arrival. Repeat ECG at 1624 (shortly before cath): QS waves now present in V2-V3, with slight STE, showing the pattern of left ventricular aneurysm morphology. Cardiologist interpretation: "Technically does not meet STEMI criteria but concerning for ischemia."

Abstract TP153: Review of Hospital Outcomes for Aneurysm Securement in SAH at a Midwest Comprehensive Stroke Center

Stroke Journal

Background:According to the 2023 guidelines for the management of patients with aneurysmal subarachnoid hemorrhages (SAH), early treatment of ruptured aneurysms reduces the risk of repeated bleeds and facilitates treatment of delayed cerebral ischemia. No differences were noted in the size or location of aneurysm.

Middle Aged Woman with Asystolic Cardiac Arrest, Resuscitated: Cath Lab?

Dr. Smith's ECG Blog

A middle-age woman with h/o hypertension was found down by her husband. This ECG is diagnostic of diffuse subendocardial ischemia. She went for a head CT and had a severe subarachnoid hemorrhage (SAH) due to ruptured aneurysm. Medics found her apneic and pulseless, began CPR, and she was found to be in asystole.

See what happens when hyperacute T-waves are missed

Dr. Smith's ECG Blog

Written by Pendell Meyers, edits by Steve Smith A man in his 60s with history of hypertension and MI 10 years ago, with PCI, presented to an outside hospital complaining of chest pain that started while mowing the lawn. His chest pain was located in the central chest, non-radiating, and associated with diaphoresis, nausea, and vomiting.
