What is an essential immediate action in suspected myocardial infarction?

• A. Call 999.
• B. Ignore symptoms.
• C. Lie down.
• D. Take antacid.

Answer: (A)

When a person has symptoms suggesting a heart attack, acting quickly is crucial because heart tissue is damaged the longer blood flow is blocked. The most important immediate action is to summon emergency medical services right away. Professional responders can perform a rapid on-site assessment, start treatments such as ECG monitoring and, if appropriate, give medications like aspirin, and arrange urgent transport to a hospital equipped for reperfusion therapy. This rapid access to definitive treatment minimizes heart muscle injury and improves survival chances.

While waiting for help, keep the person calm and seated if possible, monitor their breathing, and be ready to perform CPR if they lose consciousness. Avoid delaying care by trying home remedies or assuming the pain is something else—taking an antacid or lying down to rest does not address the emergency and can waste precious time. Ignoring symptoms is dangerous.
