2023 Angina Ischemia 
Cardiology Update
JANUARY 14, 2024
The perplexing landscape of angina with nonobstructive coronary arteries (ANOCA) encompasses diverse pathophysiological entities, including coronary microvascular disease (CMD), coronary artery spasm, and the enigmatic myocardial bridging (MB).

The ORBITA-2 trial ( NCT03742050 ) investigated the efficacy of Percutaneous Coronary Intervention (PCI) compared to placebo in 301 patients with stable angina. Results revealed ischemia in one cardiac territory in 80% of patients, two territories in 17%, and three territories in 2%. 2023;Epub ahead of print. N Engl J Med.

This confirms that the pain was ischemia and is now resovled. For more on MINOCA — See My Comment in the November 16, 2023 post in Dr. Smith's ECG Blog ). The cardiology fellow agreed with plan for emergent cath and escorted the patient to the cath lab. The i nitial hs troponin I returned 75%.

After a series of experiments in animals and peripheral vessels, he proved with a single patient N-1 study that effectively treated refractory LAD angina in a 38-year-old man in 1977. No one has questioned the efficacy of PCI for true angina with a critical lesion. ORBITA-2 came in 2023. 2023 Dec 21;389(25):2319-2330.

Whether stenting a narrowed coronary artery improves symptoms such as chest pain (angina) or shortness of breath is a very different question. Share Angina The classic definition of angina involves the sensation of tightness in the centre of the chest that is brought on with exertion and is relieved with rest. The result?

The baseline ECG is basically normal with no ischemia. You can see in the lead-specific analysis that she "sees" the STD in V5, V5, and II, with STE in aVR as signs of "Not OMI", because subendocardial ischemia pattern is not the same as OMI. In my opinion, I think it looks more like subendocardial ischemia.

This proves effective treatment of the recurrent ischemia. The patient had no further symptoms of ischemia. Serial EKG is very high yield diagnostic test in patients with stuttering angina. EKG 3 is diagnostic for developing re-occlusion, and EKG 4 proves that the nitrates relieved the ischemia. =
