Type 2 Myocardial Infarction. Type 2 myocardial infarction T2MI is frequently encountered in clinical practice and associated with adverse outcomes. T2MI occurs most frequently due to noncoronary etiologies that alter myocardial oxygen supply andor demand. A condition called type 2 myocardial infarction T2MI. The diagnosis of T2MI is often confused with acute nonischemic myocardial injury in part because of difficulties in delineating the nature of.
As with any MI subtype there must be clinical evidence of myocardial ischemia to make the diagnosis. If this were the case the DRG falls into the Acute Myocardial Infarction sets MS-DRGs 280-285 with higher weights than MS-DRG 311. Myocardial infarction type 2 T2MI has been a focus of attention. Invasive treatment strategies and cardioprotective medications were less used. Acute myocardial infarction MI can occur from increased myocardial oxygen demand andor reduced supply in the absence of acute atherothrombotic plaque disruption. On the other hand the oxygen deprivation in type 2 MI is not caused by atherosclerotic plaque rupture in a coronary artery but rather by an acute stressor such as an acute gastrointestinal bleed with a precipitous drop in hemoglobin or a sustained tachyarrhythmia with clinical manifestations of myocardial ischemia.
Most patients presenting with spontaneous myocardial infarction MI tend to have type 1 MI characterized by coronary plaque rupture or erosion and superimposed thrombosis.
These patients were older predominantly women and had more comorbidities. The diagnosis of T2MI is often confused with acute nonischemic myocardial injury in part because of difficulties in delineating the nature of. These patients were older predominantly women and had more comorbidities. But a substantial proportion have type 2 MI characterized by an imbalance between myocardial oxygen supply and demand precipitated by an extracardiac stressor such as. Coronary artery spasm coronary embolism anaemia arrhythmias hypertension or hypotension. In this real-life study 71 of myocardial infarctions were classified as type 2 AMI.
