The clinical manifestation of myocardial infarction (MI) include/includes:

CONCEPT:

• Acute myocardial infarction, also known as a heart attack, is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage.
• ECG changes in myocardial infarction develop transmural ischemia.
• In the first hours and days after myocardial infarction, some changes can occur on the ECG. First, large peak T waves (or hyperacute T waves), then ST elevations, then negative T waves, and finally pathological Q waves develop.
• Symptoms of myocardial infarction include severe chest pain that radiates from the left arm to the neck, shortness of breath, sweating, nausea, vomiting, abnormal heartbeat, anxiety, fatigue, weakness, tension, depression, and other factors.

EXPLANATION:

• The client is cold and clammy and has severe chest pain with dyspnea. The priority of action is to place the client in semi-fowler's position.
• This position helps in the expansion of the thoracic cavity and relieves breathing difficulty.
