5 Reasons to Go to the Emergency Room for Heart Symptoms
This site is built around one core belief: that women can take meaningful control of their heart health independently, without always needing a physician. That is true, and it matters enormously.
But there is a line. Knowing where that line falls could save your life.
Chest discomfort is the most common heart attack symptom in women, just as it is in men. Research published in the Canadian Women’s Heart Health Alliance Atlas found that chest pain was the presenting symptom in 92% of women and 91% of men diagnosed with acute coronary syndrome. What differs is what comes with it. Women are more likely than men to report accompanying symptoms such as nausea, unusual fatigue, indigestion, dizziness or palpitations, 61.9% compared with 54.8%, and that varied pattern is exactly what makes chest discomfort harder to read as cardiac.
This article is not about fear. It is about information. Knowing these five situations means you will never second guess yourself when it matters most.
If you are experiencing some of the symptoms below, call 911 now.
Do not drive yourself. Do not wait to see if it passes. EMS teams can begin treatment on the way to hospital. Minutes matter.
1. You have heart attack symptoms
According to the Heart and Stroke Foundation of Canada, the most common heart attack sign is chest pain or discomfort, but not always. Women often have associated symptoms that are subtler and easier to dismiss.
Chest discomfort: tightness, pressure, squeezing, fullness, pain, burning or heaviness
Chest discomfort that is new, unexplained, or feels different from before
Chest discomfort that lasts more than a few minutes, or that goes away and comes back
Shortness of breath, with or without chest discomfort
Pressure or pain in the lower chest or upper abdomen
Upper back pressure, sometimes described as a rope tightening around the chest
Pain or discomfort in the arms, neck, jaw or shoulder
Dizziness, lightheadedness or fainting
Extreme, unusual fatigue
Nausea or vomiting
Breaking out in a cold sweat
This list follows the emergency signs published by the Heart and Stroke Foundation of Canada and the American Heart Association.
While you wait for the ambulance, Heart and Stroke advises that you stop all activity, sit or lie down in whatever position is most comfortable, take your normal dose of nitroglycerin if it has been prescribed to you, and chew and swallow ASA (Aspirin) if you are not allergic or intolerant: either one 325 mg tablet or two 81 mg tablets. Do not take acetaminophen or ibuprofen instead of ASA.
Mild does not mean minor. Some heart attacks begin slowly with mild discomfort. Subtle signs can still be deadly if you do not get help right away.
2. You are trying to diagnose it yourself
You cannot rule out a heart attack at home. No amount of self-assessment, symptom checking or waiting to see substitutes for an electrocardiogram and a blood test. That is the entire point of this section.
Women are exceptionally good at producing an alternative explanation. Heartburn. Something I ate. A pulled muscle. Anxiety. Poor sleep. Perimenopause. Stress at work. I am too young. It is on the wrong side. It went away, so it cannot have been serious.
Every one of those explanations is plausible. That is the problem. They are plausible enough to buy an hour, and then another one.
The research describes the pattern directly. The CWHHA Atlas reports that women may minimize their symptoms, consult with family and friends first, weigh caregiving responsibilities and concerns for their families, and as a result delay seeking care for their chest pain.
Calling a friend to ask what she thinks is not a diagnostic test. Searching your symptoms is not a diagnostic test. An ECG and a troponin blood test are diagnostic tests, and both happen in an emergency department. As the Mayo Clinic puts it, only skilled medical professionals can determine whether someone is having a heart attack.
3. You are worried about the wait
The waiting room is not the queue you are in. Canadian emergency departments do not see patients in the order they arrive. They see them in order of clinical urgency, using the Canadian Triage and Acuity Scale, a five level system used nationally.
Chest pain that sounds cardiac is triaged at CTAS Level 2, Emergent, the second highest of the five levels. Standard practice is to perform an ECG on every patient presenting with chest pain with cardiac features, with physician review within 15 minutes, specifically so that a heart attack is not missed.
The long waits you have heard about, and the ones you may have personally sat through, belong to CTAS Levels 4 and 5. Sprains. Rashes. Sore throats. Those patients wait because someone with possible cardiac symptoms is being seen ahead of them. If you arrive with chest discomfort, you are the reason the waiting room is slow, not a casualty of it.
Arriving by ambulance moves you further forward, not simply faster. Paramedics assign a CTAS level at your side and again on arrival, and destination decisions can follow local cardiac and stroke bypass protocols, meaning EMS may take you to the hospital best equipped to treat you rather than the closest one. Treatment begins in the vehicle. None of that is available in your own car.
A previous long wait tells you nothing about this visit. It tells you what your triage level was last time.
4. You are afraid of overreacting
A normal result is a good outcome, not a wasted trip. Emergency physicians are not irritated when a cardiac workup comes back clean. Ruling out a heart attack is a successful emergency department visit. It is what the department exists to do.
The reasons women give for staying home are consistent, and none of them survive contact with the stakes:
I do not want to make a fuss. The fuss is proportionate. Heart disease and stroke are the leading cause of premature death in women in Canada.
Someone sicker needs the bed. Triage decides that, not you, and it decides in seconds.
What if it is nothing and I look ridiculous? You will not. And you will know.
I will wait until someone can drive me. Do not. Call 911 so treatment can start on the way.
I will go tomorrow if it is still there. Heart muscle does not recover once it dies. Time is the treatment.
There is a system level reason this matters more for women. Canadian research on chest pain protocols for women in the emergency department reports that women with acute coronary syndrome have worse outcomes than men, driven by misdiagnosis or missed diagnosis, delayed care and underuse of guideline directed therapy. Researchers describe a pattern of “unders”: under awareness, under diagnosis, under treatment.
You cannot fix the system from your kitchen. You can remove the one delay that is entirely within your control, which is your own.
5. You have stroke symptoms
Stroke is a separate emergency with the same instruction: call 911 immediately. Even a 25-minute delay in stroke treatment can leave patients with severe disability. Use the FAST test.
F - Face: Is one side of the face drooping?
A - Arms: Can you raise both arms equally?
S - Speech: Is speech slurred or jumbled?
T - Time: Call 911 immediately
Other stroke signs to know: sudden numbness or weakness of the leg, sudden confusion or trouble understanding, sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness or loss of balance, and a sudden severe headache with no known cause.
Do not drive to the hospital. An ambulance will bring you to the hospital best equipped for stroke care. Stroke symptoms within the treatment window are triaged at CTAS Level 2, which can trigger stroke team activation or a direct to CT protocol.
If the symptoms disappear, still go. A transient ischemic attack, sometimes called a mini stroke, produces the same symptoms for less than 24 hours. Even when they resolve quickly, see a health care provider. Without treatment you may be at risk of a stroke within five years.
Note the time your symptoms started. Treatment eligibility depends on it. Write it down or tell the 911 operator.
Why women wait too long - and why you should not.
Research consistently shows that women delay calling for emergency help longer than men do, and that the delay costs them. A study presented at the American College of Cardiology found that women were nearly twice as likely to die in hospital compared with men, 12% versus 6%, with women waiting an average of one hour before calling emergency services compared with 45 minutes for men. A later Swiss study reported by the same organisation found women waited 37 minutes longer than men to seek treatment.
Behavioural research consistently identifies the same reasons. A 2025 qualitative study in Frontiers in Global Women’s Health found women who endured symptoms for days before seeking help, often only after consulting someone else first:
- They do not recognise their symptoms as cardiac, because the symptoms differ from the classic male presentation
- They attribute symptoms to stress, anxiety, indigestion or aging
- They do not want to worry family members, or be seen as overreacting
- They wait to see if symptoms improve on their own
- They feel they should finish what they are doing first
- They are concerned about the cost or inconvenience of going to the ER
None of these reasons is worth your life. The emergency room exists for exactly these situations. You are not overreacting. You are not being dramatic. You are doing the right thing.
Frequently asked questions.
Should I drive myself to the hospital if I think I am having a heart attack?
No. Call 911. Paramedics can begin treatment on the way and can route you to the hospital best equipped for cardiac care. Driving yourself or having a friend drive you delays treatment and puts others at risk.
What if my symptoms go away before I get to the hospital?
Go anyway. Symptoms that resolve can indicate unstable angina or a transient ischemic attack, both of which warn that a larger event may follow. Resolution is not reassurance.
What should I say at triage?
Use the word chest and the word heart. Say: “I have chest discomfort and I am concerned about my heart.” Give the time your symptoms started. Vague descriptions such as “I have been feeling off” do not carry the same triage weight.
I have been told before that it was anxiety. Does that change anything?
No. A previous non-cardiac diagnosis does not exclude a cardiac event now. Anxiety and heart disease also occur together frequently. Each episode needs its own assessment.
What should I bring with me to the emergency room?
A list of your current medications and doses, your known allergies, any previous cardiac history, and the time your symptoms began. If you have prescribed nitroglycerin, bring it.
Can I have a heart attack with normal cholesterol and no family history?
Yes. Women also experience causes of heart attack that occur without significant blockage, including spontaneous coronary artery dissection. Normal results on earlier tests do not rule out an event today.
