The re-perfusion injury is a consequence of the calcium and sodium uptake from the cardiac cells and the release of oxygen radicals during reperfusion. No-reflow phenomenon—when blood is still unable to be distributed to the affected myocardium despite clearing the occlusion—also contributes to myocardial injury. Topical endothelial swelling is one of many factors contributing to this phenomenon. Diagnosis
Criteria
A myocardial infarction, according to current consensus, is defined by elevated cardiac biomarkers with a rising or falling trend and at least one of the following:
Symptoms relating to ischemia
Changes on an electrocardiogram (ECG), such as ST segment changes, new left bundle branch block, or pathologic Q waves
Changes in the motion of the heart wall on imaging
Demonstration of a thrombus on angiogram or at autopsy. Types
A myocardial infarction is usually clinically classified as an ST-elevation MI (STEMI) or a non-ST elevation MI (NSTEMI). These are based on ST elevation, a portion of a heartbeat graphically recorded on an ECG. STEMIs make up about 25–40% of myocardial infarctions. A more explicit classification system, based on international consensus in 2012, also exists. This classifies myocardial infarctions into five types:
Spontaneous MI related to plaque erosion and/or rupture fissuring, or dissection
MI related to ischemia, such as from increased oxygen demand or decreased supply, e.g.
The extent of repetition in itself might serve as an additional contextualization or paralinguistic cue, to "extend the lexical meaning of the words, add character to the sentences, and allow fine-tuning and personalisation of the message". Computer representations
In computing, several ellipsis characters have been codified, depending on the system used. In the Unicode standard, there are the following characters:

Unicode recognizes a series of three period characters (U+002E) as compatibility equivalent (though not canonical) to the horizontal ellipsis character.In HTML, the horizontal ellipsis character may be represented by the entity reference &hellip; (since HTML 4.0), and the vertical ellipsis character by the entity reference &vellip; (since HTML 5.0). Alternatively, in HTML, XML, and SGML, a numeric character reference such as &#x2026; or &#8230; can be used. In the TeX typesetting system, the following types of ellipsis are available:

In LaTeX, note that the reverse orientation of \ddots can be achieved with \reflectbox provided by the graphicx package: \reflectbox{\ddots} yields . With the amsmath package from AMS-LaTeX, more specific ellipses are provided for math mode. The horizontal ellipsis character also appears in the following older character maps:

in Windows-1250—Windows-1258 and in IBM/MS-DOS Code page 874, at code 85 (hexadecimal)
in Mac-Roman, Mac-CentEuro and several other Macintosh encodings, at code C9 (hexadecimal)
in Ventura International encoding at code C1 (hexadecimal)Note that ISO/IEC 8859 encoding series provides no code point for ellipsis.
