Question

a) 12 hours
b) 24 hours
c) 48 hours
d) 72 hours

Answer 1

The majority of deaths from Acute Myocardial Infarction happen within the first 24 hours of symptom onset, making prompt medical attention crucial.

Step-by-step explanation:

Most deaths caused by Acute Myocardial Infarction (AMI), commonly known as a heart attack, occur within the first 24 hours after the onset of signs and symptoms. Acute myocardial infarction is myocardial necrosis resulting from acute obstruction of a coronary artery. Symptoms include chest discomfort with or without dyspnea, nausea, and/or diaphoresis. Diagnosis is by electrocardiography (ECG) and the presence or absence of serologic markers. Therefore, the correct answer is b) 24 hours. During this critical period, the heart muscle begins to suffer irreversible damage due to the lack of blood flow and oxygen. Prompt medical attention is essential for survival and to minimize heart damage.
