Are impaired subendocardial wall thickening and post-systolic shortening signs of critical myocardial ischemia in patients with flow-limiting coronary stenosis?
Combined assessment of both subendocardial contractile impairment and PSS is very useful in identifying a severely hypoperfused left ventricular wall even without visual wall motion abnormality.
Medical ICU patients who developed new-onset AF experienced a 2-fold increase in the odds of in-hospital mortality and death at 60 days. Further research investigating contributing factors to new-onset AF and potential treatments is warranted.
