The World Health Organization has three criteria for a diagnosis of MI:
- a patient history of severe, prolonged chest pain.
- unequivocal electrocardiogram (ECG) changes that include abnormal and persistent Q waves.
- changes in serial cardiac biomarker levels that indicate myocardial injury and infarction.
In this manner, how is an anterior myocardial infarction treated?
Beta blockers, glyceryl trinitrate and possibly ACE inhibitors work in this way. All patients with a suspected myocardial infarction should be given aspirin. It is a powerful antiplatelet drug, with a rapid effect, which reduces mortality by 20%. Aspirin, 150-300 mg, should be swallowed as early as possible.
Hereof, what are 4 signs of myocardial infarction?
What are the symptoms of acute myocardial infarction?
- pressure or tightness in the chest.
- pain in the chest, back, jaw, and other areas of the upper body that lasts more than a few minutes or that goes away and comes back.
- shortness of breath.
- sweating.
- nausea.
- vomiting.
- anxiety.
- feeling like you’re going to faint.
What are common complications after an MI?

- Pericarditis. …
- Ventricular septal defect. …

- Ruptured papillary muscles. …
- Dressler’s syndrome.
What are six common non cardiac causes of chest pain?
What are the most common causes of noncardiac chest pain?
- Gastroesophageal reflux disease (GERD). …
- Esophageal muscle spasms. …
- Achalasia. …
- Esophageal hypersensitivity. …
- Inflammation of the esophagus. …
- Abnormal esophageal tissue.
What causes anterior wall MI?
An anterior myocardial infarction results from occlusion of the left anterior descending coronary artery. This can cause an ST elevation myocardial infarction or a non-ST segment elevation myocardial infarction.
What is anterior wall MI?
Anterior myocardial infarction is associated with a decrease in blood supply to the anterior wall of the heart. Classification of anterior myocardial infarction is based on EKG findings as follows: Anteroseptal – ST-segment elevation in leads V1 to V4. Anteroapical (or mid-anterior) – ST-segment elevation in leads V3- …
What is the drug of choice for myocardial infarction?
The pain of myocardial infarction is usually severe and requires potent opiate analgesia. Intravenous diamorphine 2.5–5 mg (repeated as necessary) is the drug of choice and is not only a powerful analgesic but also has a useful anxiolytic effect.
What is the most common site of an MI?
The most common location of myocardial infarction was anterior wall together with inferior wall. Percentage of neutrophil, serum level of CRP and ESR increased in most cases.
What tests confirm a diagnosis of myocardial infarction?
Tests available include: Cardiac Troponin I or Troponin T – which are both very sensitive and specific and are the recommended laboratory tests for the diagnosis of MI.
When should you suspect posterior MI?
ST elevation in the posterior leads of a posterior ECG (leads V7-V9). Suspicion for a posterior MI must remain high, especially if inferior ST segment elevation is also present. ST segment elevation in the inferior leads (II, III and aVF) if an inferior MI is also present.
Which coronary artery is affected in anterior MI?
Anterior STEMI usually results from occlusion of the left anterior descending artery (LAD). Anterior myocardial infarction carries the poorest prognosis of all infarct locations, due to the larger area of myocardium infarct size.
Which leads show anterior MI?
The ECG findings of an acute anterior myocardial infarction wall include: ST segment elevation in the anterior leads (V3 and V4) at the J point and sometimes in the septal or lateral leads, depending on the extent of the MI. This ST segment elevation is concave downward and frequently overwhelms the T wave.
