Most of us have a pretty good idea what a heart attack is supposed to look like. Someone suddenly grabs their chest, collapses, and everyone knows immediately that something is wrong.
Sometimes heart problems do announce themselves that dramatically.
But often they don’t.
Your heart may give you quieter clues first: getting unusually winded on your normal walk, feeling pressure in your chest when you climb stairs, noticing your heart racing for no obvious reason, or suddenly having less energy than usual.
And after 50, those changes deserve a little more attention.
That doesn’t mean every episode of indigestion or shortness of breath is heart disease. Usually, there are several possible explanations.
But there are certain symptoms I don’t want you to ignore.
Here are seven.
1. Chest Pressure, Tightness, or Discomfort
Let’s start with the symptom everyone knows.
Chest pain.
But here’s something important: heart-related chest symptoms don’t always feel like pain.
Some people describe:
- Pressure
- Tightness
- Squeezing
- Heaviness
- Burning
- Fullness
- A band around the chest
You might hear someone say, “It felt like an elephant was sitting on my chest.”
But it can also be much subtler.
One pattern that particularly gets my attention is chest discomfort that occurs with physical activity and improves when you stop and rest.
For example, perhaps you notice pressure in your chest every time you walk uphill. You stop for a few minutes, it disappears, and you continue walking.
Don’t simply assume you’re out of shape.
That pattern can occur when the heart muscle isn’t receiving enough oxygen-rich blood during activity.
Dr. Mike’s Take
Don’t wait for Hollywood-style crushing chest pain before taking a symptom seriously. Heart symptoms can be surprisingly subtle—especially in older adults and people with diabetes.
2. You’re More Short of Breath Than You Used to Be
Getting winded after climbing several flights of stairs isn’t necessarily unusual.
Getting winded walking from the kitchen to the bedroom when that never bothered you before? That’s different.
Shortness of breath can have many causes, including lung disease, anemia, infections, deconditioning, and excess weight.
But it can also be related to the heart.
If the heart isn’t pumping effectively, pressure can build up and fluid may accumulate in the lungs, making breathing more difficult.
Pay particular attention to a change from your normal baseline.
If you used to walk a mile comfortably and now you’re stopping after two blocks to catch your breath, don’t automatically blame your age.
3. Your Exercise Tolerance Has Suddenly Dropped
This is one I think people overlook.
Your body often tells you something is changing through what you can—or can’t—do.
Maybe you’ve walked the same neighborhood route for years. Suddenly, the hill you’ve always climbed comfortably requires a rest halfway up.
Or perhaps you normally ride your stationary bike for 30 minutes, but now you’re exhausted after 10.
That doesn’t automatically mean heart disease.
You could be recovering from an illness. You might be anemic. Your fitness level may have declined.
But a significant unexplained decrease in exercise capacity deserves attention.
Your heart is essentially an engine. Exercise asks that engine to increase its output.
Sometimes a problem becomes noticeable during activity before it becomes obvious while you’re sitting on the couch.
Remember This
One of the most useful questions isn’t simply, “Do I have symptoms?”
It’s “Can I still do the things I could comfortably do a few months ago?”
4. Your Heart Is Racing, Fluttering, or Skipping Beats
Almost everyone occasionally notices an unusual heartbeat.
You might feel a skipped beat after too much coffee or notice your heart pounding when you’re nervous.
Often, these sensations are harmless.
But recurrent palpitations deserve a conversation with your healthcare professional—particularly if they are new.
People describe palpitations in different ways:
“My heart is fluttering.”
“It feels like it’s skipping beats.”
“Suddenly it starts racing.”
“It feels irregular.”
There are many possible causes, ranging from caffeine and stress to thyroid problems and abnormal heart rhythms.
One rhythm that becomes increasingly common with age is atrial fibrillation, or AFib.
AFib matters because it can increase the risk of stroke.
If palpitations are accompanied by chest discomfort, severe shortness of breath, fainting, or significant dizziness, seek medical attention promptly.
5. You Feel Dizzy or Faint
We’ve probably all stood up too quickly and felt a little lightheaded.
That isn’t necessarily concerning.
But unexplained or recurrent dizziness—particularly actual fainting—is different.
Your brain needs a continuous supply of blood.
If your heart rate becomes extremely slow, extremely fast, or irregular, the heart may temporarily fail to deliver enough blood to your brain.
The result can be dizziness or loss of consciousness.
Blood pressure problems, dehydration, medications, neurological conditions, and other issues can also cause these symptoms.
But unexplained fainting should not simply be dismissed as “getting older.”
It deserves evaluation.
6. Your Ankles or Legs Are Swelling
Take your socks off at the end of the day.
Do you see deep marks around your ankles?
Are your shoes suddenly tighter?
Do your lower legs look puffier than usual?
There are many causes of leg swelling. Certain medications can cause it. Vein problems are common. Sitting for long periods can contribute.
But swelling in both legs can sometimes occur when the heart isn’t pumping effectively.
Fluid begins to accumulate in the tissues, often showing up first in the feet, ankles, and lower legs.
This becomes more concerning when swelling appears along with symptoms such as shortness of breath, rapid weight gain, unusual fatigue, or difficulty breathing when lying flat.
New or unexplained swelling deserves a call to your healthcare professional.
7. You’re Unusually Tired—and Can’t Explain Why
Fatigue is tricky.
Didn’t sleep well? You’ll be tired.
Busy week? You’ll be tired.
Recovering from the flu? You’ll be tired.
But persistent, unexplained fatigue can occasionally be a clue that your cardiovascular system isn’t functioning as well as it should.
Some people with heart disease describe a noticeable change:
“I just don’t have the energy I used to.”
Normal activities suddenly feel exhausting.
This symptom can be particularly important when it occurs along with shortness of breath, chest discomfort, dizziness, or declining exercise tolerance.
Fatigue alone doesn’t diagnose heart disease.
But a major change from your normal energy level deserves attention.
Sometimes the Symptoms Aren’t in Your Chest
This is worth emphasizing.
Heart-related discomfort can sometimes be felt somewhere other than the chest.
Symptoms may involve the:
- Arm or shoulder
- Back
- Neck
- Jaw
- Upper abdomen
Some people experience nausea, sweating, lightheadedness, or shortness of breath rather than obvious chest pain.
Women, older adults, and people with diabetes may sometimes have less typical symptoms.
That’s one reason I don’t want you using severe chest pain as your only definition of a possible heart problem.
When Should You Call 911?
There is a big difference between “I should mention this to my doctor” and “I need help now.”
Call 911 for symptoms suggesting a possible heart attack or another cardiovascular emergency, particularly new or severe chest pressure, squeezing, fullness, or pain that persists or recurs, especially when accompanied by:
- Shortness of breath
- Cold sweating
- Nausea or vomiting
- Fainting or severe lightheadedness
- Sudden extreme weakness
- Discomfort spreading into the arm, back, neck, jaw, or upper abdomen
Don’t drive yourself to the emergency department if you think you may be having a heart attack.
Call 911.
I’d much rather have someone evaluated and discover that their heart is fine than have them sit at home for several hours hoping a heart attack will go away.
The Bottom Line
Your heart doesn’t always shout when something is wrong. Sometimes it whispers.
New chest pressure, unexplained shortness of breath, declining exercise tolerance, palpitations, fainting, leg swelling, and unusual fatigue can all be signs worth investigating.
Most importantly, pay attention to changes from your normal.
Don’t assume every new symptom is simply because you’re getting older.
Aging is normal.
Ignoring an important change isn’t.
