How to Recognize Stroke and Heart Attack: Key Early Warning Signs

Published: August 16, 2026  |  Category: Industry News

Stroke (commonly known as a "brain attack") and acute myocardial infarction are two common emergencies that strike suddenly, progress rapidly, and demand extremely timely treatment. For patients and their families, recognizing abnormal signs at the earliest moment and seeking help correctly can directly affect how well subsequent care connects. As a continuation of our first-aid awareness series, this article introduces the common early warning signs of stroke and heart attack, along with the right way to respond. Please note that this content is for general health education only and cannot replace professional diagnosis — any suspected symptoms should be evaluated promptly by qualified healthcare professionals.

1. Stroke: Remember the "FAST" Recognition Method

When a stroke occurs, blood supply to the brain is abruptly interrupted and brain tissue is deprived of oxygen. Early recognition and rapid transport to hospital make a significant difference to subsequent treatment. A widely used public recognition method is summarized in four steps, "FAST":

Face — ask the person to smile and observe whether one side of the face is asymmetric or the mouth corner droops; Arms — ask the person to raise both arms and observe whether one arm is weak or drifts downward; Speech — ask the person to say a complete sentence and observe whether speech is slurred or difficult to understand; Time — if any of the above is abnormal, note the time of onset immediately and call emergency services. It is worth noting that not every stroke patient shows all of these signs at once — some may have only a single symptom. Whenever stroke is suspected, do not "wait and see" — seek professional emergency help immediately.

2. Heart Attack: Watch for Typical Chest Pain and Atypical Signs

An acute myocardial infarction is an emergency in which a coronary artery becomes suddenly blocked, causing heart muscle to lose blood supply. The most typical symptom is persistent chest pain or a squeezing sensation in the chest, often radiating to the left shoulder, left arm, back, or jaw, and possibly accompanied by heavy sweating, shortness of breath, or nausea. However, heart attacks do not always begin with severe chest pain: some people — especially older adults, women, and people with diabetes — may have atypical symptoms such as fatigue, stomach discomfort, difficulty breathing, or a vague "something just feels off." For this reason, when someone near you develops unexplained chest discomfort accompanied by cold sweats or pallor, treat it as an emergency and leave the assessment to professional medical staff.

3. Seeking Help Correctly: A Three-Step Response

When stroke or heart attack is suspected, the key to on-site response is "stay calm, act fast, stay organized": Step one, call emergency services (120) immediately and clearly state the patient's age, symptoms, time of onset, and location; step two, keep the patient still in a comfortable position, avoid agitation and strenuous movement, and do not give food, water, or medication on your own; step three, note the time of onset and any medications taken, and share the patient's medical history and regular medications with emergency personnel. A special reminder: when a heart attack or stroke is suspected, the patient should not drive themselves to hospital, and family members should not move the patient without professional guidance — doing so may worsen the condition. While waiting for emergency services, keep the patient's airway clear; if the patient loses consciousness or breathes abnormally, begin CPR under professional guidance — a skill introduced in our previous article.

4. From Recognition to Transport: Professional Coordination Makes Care Better Prepared

Stroke care emphasizes "time is brain," and heart attack care emphasizes "time is muscle" — both point to the core goal of reaching a hospital with the appropriate treatment capability (such as a stroke center or chest pain center) as soon as possible. For patients at primary-level hospitals, in areas with limited local treatment capacity, or at long distances from specialized centers, professional medical transport makes a real difference: the treating medical team first assesses whether transport is feasible, and then a qualified transport provider coordinates aviation or ground resources to connect pre-hospital, in-hospital, and transfer phases seamlessly. Whether to transfer, and by what means, must be decided based on professional medical institution assessment. As an aviation medical coordination provider, BOOZOUN can coordinate medical charter flights, helicopters, and ground ambulances for patients in need, connecting the referring and receiving hospitals so that the chain of "recognition — call for help — transport — treatment" runs as smoothly as possible.

The value of first-aid knowledge lies in being "usable, and used correctly" at the critical moment. Recognizing the signs, seeking help properly, and arranging professional transport — every link affects treatment outcomes. BOOZOUN is ready to work with every family to reserve the most precious resource of all — time — for professional care.
