Unexplained fatigue, shortness of breath, or mild chest discomfort are often overlooked. Yet these may be prodromal symptoms, early indicators of an impending heart attack or stroke. Life gets busy, and when symptoms are subtle or come and go, it’s easy to brush them off. But these early warning signs are your body’s way of signaling that something serious could be on the horizon.
Take John, a 54-year-old office worker. For three weeks, he felt unusually tired, got winded while walking, and noticed a constant pressure in his chest. He chalked it up to stress and decided not to see a doctor. Then, one morning, he collapsed at work. It was a heart attack that doctors later said could have been prevented with earlier attention.
According to the World Heart Federation, nearly 80% of heart disease and stroke cases are preventable. But that’s only possible if we listen to our bodies. Stroke can also send quiet signals days or even weeks ahead, like brief vision changes, sudden dizziness, or short episodes of numbness that quickly pass. These are easy to dismiss but shouldn’t be. So, keep reading to learn about the top 6 signs of a heart attack a month before and why it’s so important not to ignore them.
6 Warning Signs of a Heart Attack or Stroke a Month Before
Prodromal symptoms are early warning signs that appear before the onset of a major illness or medical event, such as a heart attack or stroke. These symptoms can develop days, weeks, or even months in advance, giving the body a chance to signal that something is wrong.
Heart attacks and strokes rarely happen without warning. The body often gives early signals, sometimes weeks before the event. A 2023 study published in The Lancet found that 1 in 2 people who suffered a heart attack had symptoms up to four weeks prior, yet most of them didn’t seek medical help in time. So, here are 6 signs of a heart attack a month before that may help you recognize prodromal symptoms early.:
1. Chest Discomfort or Pain
Every year, about 805,000 people in the U.S. have a heart attack, and for 605,000, it’s their first. Chest discomfort is a common early sign, but not all chest pain means a heart attack. Heartburn causes a burning pain behind the breastbone, often after eating, and may worsen when lying down. It’s caused by stomach acid and is not related to the heart. However, Angina is chest pain from reduced blood flow to the heart. It feels like pressure or tightness, usually occurs during activity or stress, and goes away with rest. It may feel like squeezing or heavy pressure and can spread to the left arm, neck, jaw, back, or stomach. If you experience new or unusual chest pain that lasts, seek emergency care immediately.
2. Shortness of Breath
Shortness of breath without a clear reason is an important early warning sign. It can happen even when you’re resting or doing light activities. Some people may also feel breathless while lying down. This happens because the heart is having trouble pumping blood properly. Shortness of breath can also be a symptom of certain types of strokes, such as brainstem strokes, which affect the area of the brain that controls breathing and other vital functions.
A study published in the British Medical Journal found that 42% of women who had a heart attack reported shortness of breath as a main symptom. If you suddenly find yourself breathing harder than usual or feeling out of breath, take it seriously. It may point to a heart or stroke-related problem, especially if it happens along with other symptoms like chest discomfort or fatigue. Consult a doctor right away.
3. Unusual Fatigue
Feeling extremely tired without any clear reason can be an early sign of a heart attack or stroke. This type of fatigue is different from normal tiredness. It does not improve with rest and can last for weeks. Women are more likely than men to experience unusual fatigue before a heart attack. In fact, it was reported in the BMJ journal that 70% of women experience fatigue.
You may feel weak, exhausted, have sleep disturbances, anxiety or be unable to perform simple tasks. Climbing stairs, walking short distances, or carrying groceries may seem difficult. If you experience persistent and unexplained fatigue, consult a doctor. It could be a sign of reduced oxygen supply to the heart.
4. Dizziness or Lightheadedness
Frequent dizziness or feeling faint can be a warning sign of heart trouble. It often occurs when the brain doesn’t get enough oxygen-rich blood, a condition known as hypoperfusion. This may happen with low blood pressure, obesity, irregular heart rhythms (like bradycardia), or poor heart function.
Dizziness can also result from orthostatic hypotension, a sudden drop in blood pressure when standing, or dehydration, both of which may seem harmless but could signal underlying heart problems.
A study in Mayo Clinic Proceedings found that about 15% of heart-related emergency cases involved dizziness, especially among older adults.
5. Irregular Heartbeat
A sudden change in your heart rhythm, whether too fast or too slow, may indicate a heart problem. Some people feel their heart skipping beats, racing, or pounding without any reason. This condition is known as arrhythmia, and it can significantly raise the risk of both heart attack and stroke. In particular, atrial fibrillation (AFib), a common type of arrhythmia, can cause blood clots that may travel to the brain and trigger a stroke. Risk factors like older age, excessive alcohol use, and thyroid disorders (both overactive and underactive) can contribute to arrhythmias, sometimes showing up as early warning signs weeks before a major cardiac event. According to a study published in StatPearls Publishing, the number of people with atrial fibrillation will double or even triple by 2050. If your heart rhythm feels unusual and lasts for more than a few seconds, consult a doctor. Ignoring this symptom can lead to serious complications.
6. Numbness or Weakness in the Face, Arm, or Leg
Numbness or weakness, especially on one side of the body, is a major warning sign of a stroke. It may start with a tingling feeling in the face, arm, or leg. The weakness may come and go, making it easy to ignore. However, it usually gets worse over time.
This symptom happens when the brain does not get enough blood due to a blocked artery. You may also notice slight facial drooping, arm weakness, or slurred speech. These common early signs are remembered by the acronym FAST (Face, Arms, Speech, Time). Early treatment can reduce the risk of long-term disability by up to 80% as reported in a study in Lancet Neurology.
Symptoms in Men and Women- Key Differences
Heart attack and stroke symptoms can show up differently in men and women. Women often experience subtle or unusual prodromal symptoms, while men are more likely to have the classic signs. Several risk factors can increase a person’s chances of developing these symptoms or experiencing a serious cardiovascular event. These include high blood pressure, diabetes, smoking, a family history of heart disease or stroke, a sedentary lifestyle, and high cholesterol. These risks affect both men and women but may influence symptom presentation differently.
| Symptom | Men | Women |
| Chest Pain | Intense chest pain or pressure, often described as a “heavy weight” on the chest. | Mild chest discomfort, burning, tightness, or aching instead of sharp pain. Pain may be absent in some cases. |
| Shortness of Breath | Usually occurs with chest pain. May feel breathless after physical activity. | It can occur suddenly without chest pain. May feel breathless even while resting or doing light activities. |
| Fatigue | Less common as an early warning sign. Usually occurs after the heart attack starts. | Extreme, unexplained tiredness that can last for weeks before a heart attack. Feeling exhausted even after minimal effort. |
| Pain Locations | Typically felt in the left arm, chest, or jaw. Pain is often severe and noticeable. | Pain may appear in the back, neck, shoulders, stomach, or both arms. It may feel like muscle strain. |
| Nausea and Vomiting | Rarely experienced before a heart attack. More common during or after the event. | More likely to feel nauseous, vomit, or have indigestion-like symptoms before a heart attack. |
| Dizziness and Weakness | May feel lightheaded, but it is usually accompanied by chest pain or other symptoms. | More likely to feel faint, weak, or dizzy without chest pain. This may happen suddenly and without warning. |
8 Reasons Why Symptoms Appear Before a Heart Attack
According to the CDC, someone in the U.S. has a heart attack every 40 seconds. They do not happen suddenly but develop over time due to blocked arteries. The body gives early warning signs as the heart struggles to pump blood properly. Below are 8 reasons why prodromal symptoms appear before a heart attack.
- Reduced Blood Flow
Coronary heart disease is the most common type of heart disease and the leading cause of death from heart-related conditions. According to the National Heart, Lung, and Blood Institute, it caused 371,506 deaths in the U.S. in 2022.
The condition develops when arteries become narrow or blocked, reducing blood flow to the heart. This can lead to warning signs like chest pain, dizziness, and fatigue, and may eventually trigger a heart attack if not addressed.
- Oxygen Shortage
The heart relies on a steady oxygen supply to function properly. When arteries become narrowed or blocked, oxygen flow is reduced, often causing symptoms like breathlessness and weakness weeks before a heart attack. This condition is commonly linked to angina, which causes chest pain due to a temporary oxygen shortage. According to the CDC, about 9 million adults in the U.S. experience angina, which shows its role as an early warning sign of a heart attack.
- Inflammation
Swelling in the arteries can cause pain, irregular heartbeats, or pressure in the chest, signaling heart problems. Inflammation weakens the arterial walls and makes plaque more likely to rupture, which can block blood flow and trigger a heart attack.
- Nerve Sensitivity
The heart and brain communicate through nerves. As heart function declines, the body sends pain signals, often felt in the chest, arms, or jaw.
This referred pain is a frequent prodromal symptom of cardiac distress. That is why some people feel pain in their left arm or jaw even if there’s no chest pain.
- Blood Clot Formation
Clots form inside narrowed arteries, slowing blood flow. This process can cause mild symptoms before completely blocking the artery.
These early signs may appear as unstable angina or transient symptoms like chest tightness or discomfort that goes away with rest. This often indicates the presence of a forming clot and reduced oxygen supply to the heart.
- Heart Strain
The risk of a heart attack increases with age, particularly after 45 years for men and 55 years for women, according to the National Heart, Lung, and Blood Institute study. A struggling heart has to work harder, leading to symptoms like fatigue and irregular heartbeats before a full-on heart attack occurs. Experiencing fatigue during routine tasks, such as climbing stairs or walking short distances, may signal heart strain.
- Plaque Instability
Plaque instability occurs when fatty deposits in the arteries rupture or become inflamed, leading to clot formation. This can partially block blood flow, causing early warning signs like chest discomfort or fatigue. These symptoms often appear before a heart attack and signal that a major cardiac event may be imminent.
- Silent Ischemia
Silent ischemia happens when blood flow to the heart is reduced without causing obvious pain. It often goes unnoticed, but it can still damage the heart over time. People with diabetes or high blood pressure are especially at risk. Subtle symptoms like fatigue or shortness of breath may be early clues.
