If someone near you is having a heart attack, your words matter more than you might think. What you say to the person, and how you say it, can directly affect how much damage their heart sustains. Staying calm and speaking with quiet confidence helps keep their stress hormones from spiking, which protects the heart muscle during those critical first minutes. Here’s exactly what to say to the person, what to tell 911, and what to avoid.
Why Your Words Physically Matter
A heart attack happens when blood flow to part of the heart is blocked, and the heart muscle starts to die. Panic makes this worse in a measurable way. When a person is frightened, their body floods with stress hormones that constrict blood vessels, increase the heart’s demand for oxygen, and can even trigger dangerous heart rhythms. Research published in the European Heart Journal has shown that this surge of stress chemicals can worsen a heart attack, cause additional coronary vessel spasm, and destabilize the blockage itself. In short, a terrified heart attack victim’s body is working against them. Your calm voice is a legitimate medical intervention.
What to Say to the Person
Start with something direct and reassuring. “I’m here with you, and I’m calling for help right now.” That single sentence does two things: it tells them they’re not alone, and it tells them action is already happening. Both reduce panic.
Keep your tone steady and low. Speak slowly. If they’re clutching their chest or looking frightened, say something like “Help is on the way. I need you to try to breathe slowly and stay as still as you can.” People having a heart attack are almost always conscious and alert, so they can hear and respond to you. Guiding them to sit down (not lie flat) and lean against a wall or chair keeps them comfortable and reduces the workload on their heart.
Ask them directly: “Do you have any heart medication or aspirin nearby?” If they carry nitroglycerin, help them take it as prescribed. If aspirin is available, current guidelines recommend having them chew (not swallow whole) a full 325 mg tablet. Chewing gets it into the bloodstream faster, where it helps prevent the clot from growing. Say clearly: “Chew this aspirin for me, don’t swallow it whole.”
As you wait for paramedics, keep talking. “You’re doing great. Help will be here soon. Just keep breathing nice and slow.” This isn’t empty comfort. You are actively keeping their stress response lower, which protects the heart.
What to Tell the 911 Dispatcher
When you call 911, the dispatcher will guide you through a specific set of questions. Having clear answers ready saves precious seconds. They will ask for:
- The exact address of the emergency, including apartment or floor number
- Your phone number in case the call drops
- Whether the person is conscious and responsive
- Whether they are breathing normally
- The person’s approximate age
Beyond those basics, describe what you’re seeing in plain language: “He’s conscious, sitting up, complaining of chest pressure that started about ten minutes ago. He’s sweating and says the pain is going into his left arm.” Mention if the person has taken aspirin or any medication. If symptoms started while you were present, tell the dispatcher exactly when. This information gets relayed to the paramedics before they even arrive, which speeds up treatment.
Stay on the line. The dispatcher may coach you through additional steps, and they need to know immediately if the person’s condition changes.
How to Recognize What’s Happening
You can’t say the right things if you don’t recognize the situation. The most common heart attack symptoms are chest pain or pressure (often described as tightness or heaviness rather than sharp pain), pain radiating into the left arm, jaw, or neck, shortness of breath, cold sweats, and nausea. Some people describe a feeling of “impending doom” that’s hard to put into words.
Less obvious signs include dizziness, unusual fatigue, and anxiety that seems to come from nowhere. Women are more likely to experience these atypical symptoms. If these issues persist for 10 minutes or more, treat it as a heart attack until proven otherwise.
One critical distinction: during a heart attack, the person is typically awake, talking, and breathing. If they collapse and become unresponsive with no pulse, that’s cardiac arrest, and the response shifts to CPR. Do not perform CPR on someone who is conscious and talking to you.
What Not to Say
“You’re too young for a heart attack” or “You look fine, it’s probably just heartburn.” These kinds of reassurances are dangerous because they encourage the person to dismiss their symptoms and delay calling for help. Heart attacks happen to people of all ages and fitness levels. If the signs are there, act on them.
Avoid dramatic reactions too. Saying “Oh my God, you’re having a heart attack!” while panicking will spike their fear and their stress hormones along with it. You don’t need to diagnose them out loud. You just need to stay calm, call 911, and keep them still and comfortable.
Don’t suggest driving to the hospital. It feels proactive, but it’s one of the most common mistakes bystanders make. Paramedics carry equipment that can begin treatment in the ambulance, and they can transmit heart data to the emergency room before arriving. A car ride offers none of that, and if the person’s heart stops en route, there’s no one to help.
While You Wait for Paramedics
The minutes between your 911 call and the ambulance’s arrival are when your presence matters most. Keep the person sitting comfortably, loosen any tight clothing around their neck or chest, and continue talking in a calm, steady voice. Monitor them for changes: are they becoming more pale, more short of breath, less responsive? If they lose consciousness and stop breathing normally, that’s when you begin CPR, pushing hard and fast in the center of the chest at a rate of 100 to 120 compressions per minute until help arrives.
When paramedics walk in, give them a quick summary: when symptoms started, what the person described feeling, whether they took aspirin or any other medication, and any changes you noticed. This handoff can save the medical team significant time. In heart attack care, every minute of delay means more heart muscle lost. The concept of a “golden hour,” borrowed from trauma medicine, applies here. Early treatment has been shown to reduce six-month mortality by roughly 13 percentage points compared to delayed care.
You don’t need medical training to be the person who makes a difference. Clear words, a calm voice, a fast call to 911, and an aspirin can change the outcome of someone’s heart attack in ways that are hard to overstate.
