What is mi?

Location of the infarction

MI’s can be located in the anterior , septal,lateral ,posterior ,or inferior walls of mostly the left ventricle of the heart

Location of the infarction

MI CLASSIFICATION:

1.ANATOMICSubendocardial(Partial area) and Transmural(Whole area) ž 2.Diagnostic– Non ST elevation [NSTEMI] and ST elevation [STEMI]

ANATOMIC Diagnostic-

Transmural(whole)

Nstemi:

  • ST segment depression
  • T wave changes
  • No Q wave development
  • Mild enzyme elevation
Nstemi

Stemi:

  • ST segment elevation
  • T wave changes
  • Q wave development
  • Enzyme elevation
  • (Troponin I, Troponin II,Creatine kinase Enzymes M & R)

Causes:

  • Smoking
  • High LDL cholesterol levels
  • High blood pressure
  • Diabetes
  • Chronic kidney diseases

SYMPTOMS

  • Severe & crushing chest pain/pressure – might radiate upto left arm or jaw Diaphoresis(sweating)
  • Nausea
  • Fatigue
  • Dyspnea
MI

OTHER SYMPTOMS:

  • Anxiety
  • Cough
  • Fainting
  • Light –hotheadedness ,dizziness
  • Nausea or vomiting
  • Palpitations-feeling like heart is beating too fast or irregularly
  • Women are more likely to have atypical symptoms than men

Risk factor:

  • Tobacco use leads to damage of blood vessels walls.The body response to this type of injury elicts to formation of atheroscerosis and its progression increases the risk of MI.
  • Hypertension
  • Diabetes mellitus
  • Hyperlipidemia
  • Lack of exercise
  • Obesity
  • High blood cholesterol

Medication:

  • Aspirin
  • Oxygen supply
  • Nitroglycerin
