A chest radiograph revealed elevation of the diaphragm.
Myocardial infarction was defined as ST-elevation myocardial infarction (chest pain and ST-elevation over 1 mm in at least two contiguous leads) or non-ST-elevation acute coronary syndrome [defined as chest pain with positive cardiac markers (troponin or creatinin kinase) and/or dynamic ST-segment changes] [ 25, 26].
For patients with high- and low-risk chest pain, baseline troponin elevation without CK-MB elevation was associated with increased risk for early and short-term adverse outcomes.
An NSTEMI is defined according to the occurrence of acute ischemic symptoms (eg, chest discomfort) and elevated cardiac biomarkers but without ST-segment elevation on the electrocardiogram.
Emergency physicians show a low rate of ECG misinterpretation in patients with chest pain and ST elevation [6]; emergency medicine residents have similar skill levels in ECG interpretation compared to medicine residents (although the overall performance was low for both disciplines rates of incorrect diagnosis were 58% for complete heart block and 8% for myocardial infarction) [7].
Increased levels of miR-1 and miR-133a were detected early just after chest pain and before elevation of CK and cTnT [ 112].
In 10 patients, diaphragmatic paralysis, shown by hemidiaphragmatic elevation on chest radiograph, or pulmonary function test results with a restrictive pattern and retention of carbon dioxide, suggested neuromuscular respiratory failure.
The diagnostic criteria were: (a) new and growing lesions, especially multiple, round nodules in the periphery of lungs on dynamic chest CT scan; (b) elevation of serum AFP levels, especially in patients with initially raised serum AFP, which decreased after liver resection.
A previously healthy 38-year-old man with no history of cardiovascular disease presented with symptoms of upper respiratory tract infection, acute chest pain, inferior ST-elevation on ECG and a troponin I >60 μg/L (normal <0.04 μg/L).
We included patients with at least 30 min of continuous typical chest pain, with ST-elevations of at least 0.2 mV in two or more anatomically contiguous leads, presenting to the emergency medical service within 6 h after symptom onset.
In response to acute occlusion of the LCA, the posterior chest leads showed more ST elevation than the other leads, and more patients had ST elevation in the posterior leads than in any other lead.
