What is a Type Two myocardial infarction?

Type 2 MI is defined as “myocardial infarction secondary to ischaemia due to either increased oxygen demand or decreased supply, e.g. coronary artery spasm, coronary embolism, anaemia, arrhythmias, hypertension or hypotension.”

What is a Type 1 myocardial infarction?

Type 1 MI is due to acute coronary atherothrombotic myocardial injury with either plaque rupture or erosion and, often, associated thrombosis. Most patients with ST-segment elevation MI (STEMI) and many with non-ST-segment elevation MI (NSTEMI) fit into this category.

Is type 2 myocardial infarction a heart attack?

Type 2 MI is distinguished from myocardial injury without acute ischemia, for example, acute heart failure and myocarditis. Type 2 MI is associated with a poor outcome. Several studies have demonstrated higher mortality rates among patients with type 2 MI as compared with patients with type 1 MI.

How is type 2 myocardial infarction diagnosed?

Diagnostic criteria for type 2 MI include the following: (1) detection of markers of cardiac myonecrosis (ie, elevated troponin concentrations); (2) clinical context lacking signs or symptoms suggestive of acute coronary syndrome or nonischemic contributors to myocardial injury (such as myocarditis); and (3) …

What is a Type 3 myocardial infarction?

The type 3 myocardial infarction was defined according to the Universal definition of myocardial infarction, that is, cardiac death with symptoms suggestive of myocardial ischemia and presumed new ischemic ECG changes or new left bundle branch block, but death occurring before blood samples could be obtained, before …

What are the different types of myocardial infarction?

A heart attack is also known as a myocardial infarction. The three types of heart attacks are: ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI)

What is a Type 3 mi?

Type 3 (MI resulting in death when biomarker values are unavailable): Sudden, unexpected cardiac death before blood samples for biomarkers could be drawn or before their appearance in the circulation.

What is the most common type of myocardial infarction?

Type 2 MI is the most common type of MI encountered in clinical settings in which is there is demand-supply mismatch resulting in myocardial ischemia. This demand supply mismatch can be due to multiple reasons including but not limited to presence of a fixed stable coronary obstruction, tachycardia, hypoxia or stress.

What is type 5 myocardial infarction?

Coronary artery bypass grafting (CABG)–related MI is termed type 5 MI. Coronary procedure–related MI ≤48 hours after the index procedure is arbitrarily defined by an elevation of cTn values >5 times for type 4a MI and >10 times for type 5 MI of the 99th percentile URL in patients with normal baseline values.

What are the 4 types of myocardial infarction?

ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.

What is a Type 2 non STEMI?

(NSTEMI) is a common diagnosis in hospitalized patients. Type 2 has been reported up to 25\% of cases of MI depending on the population studied. Type 2 NSTEMI is defined as myocardial ischemia resulting from mismatched myocardial oxygen supply and demand that is not related to unstable coronary artery disease (CAD).
