2. ST2 cardiac biomarker - Wikipedia

   en.wikipedia.org/wiki/ST2_Cardiac_Biomarker

   ST2 is a strong predictor of cardiovascular death and risk of developing new heart failure in ST Elevation Myocardial Infarction (STEMI) & NSTE-ACS patients. In patients presenting with Acute Coronary Syndrome (ACS), those in the highest quartile (above 35 ng/ml) have more than 3 times higher risk of cardiovascular death and new heart failure ...

3. ST elevation - Wikipedia

   en.wikipedia.org/wiki/ST_elevation

   12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1–V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. When there is a blockage of the coronary artery , there will be lack of oxygen supply to all three layers of cardiac muscle (transmural ischemia).

4. Acute coronary syndrome - Wikipedia

   en.wikipedia.org/wiki/Acute_coronary_syndrome

   Acute coronary syndrome is subdivided in three scenarios depending primarily on the presence of electrocardiogram (ECG) changes and blood test results (a change in cardiac biomarkers such as troponin levels): [4] ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), or unstable angina. [5]

5. Management of acute coronary syndrome - Wikipedia

   en.wikipedia.org/wiki/Management_of_acute...

   Patients with acute coronary syndrome and ST elevation are said to have ST-elevation myocardial infarction (STEMI) and they tend to have one of their coronary arteries totally blocked. [3] Damage is reversible for approximately 20 [ 4 ] -30 [ 5 ] minutes after complete obstruction of blood flow; thereafter myocardial cell death ensues and ...

6. Electrocardiography in myocardial infarction - Wikipedia

   en.wikipedia.org/wiki/Electrocardiography_in...

   The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...

7. Diagnosis of myocardial infarction - Wikipedia

   en.wikipedia.org/wiki/Diagnosis_of_myocardial...

   A normal ECG does not rule out acute myocardial infarction. Mistakes in interpretation are relatively common, and the failure to identify high risk features has a negative effect on the quality of patient care. [12] It should be determined if a person is at high risk for myocardial infarction before conducting imaging tests to make a diagnosis ...

8. Coronary artery disease - Wikipedia

   en.wikipedia.org/wiki/Coronary_artery_disease

   Diagnosis is clear-cut if ECGs show elevation of the "ST segment", which in the context of severe typical chest pain is strongly indicative of an acute myocardial infarction (MI); this is termed a STEMI (ST-elevation MI) and is treated as an emergency with either urgent coronary angiography and percutaneous coronary intervention (angioplasty ...

9. Arterial occlusion - Wikipedia

   en.wikipedia.org/wiki/Arterial_occlusion

   Serum troponin elevation is a characteristic biomarker of MI. [34] Depending on the severity of ischemia, MIs are categorized as NSTEMI or STEMI. NSTEMI stands for 'Non-ST Elevation Myocardial Infarction', [34] referencing the lack of ST-segment elevation in ECG traces. This is because in NSTEMI, only part of the myocardial wall is infarcted ...
