These serious heart conditions share similar signs.
You feel chest pain. You’re short of breath. You’re fatigued. Are you feeling symptoms of heart disease … or could it be an actual heart attack?
Most Americans don’t know all the signs that could point to heart problems. In a survey of 72,000 people conducted by the Centers for Disease Control and Prevention (CDC), 92% of respondents recognized chest pain as a symptom of a heart attack, but only 27% were aware of all major symptoms.
At the risk of sounding a bit dramatic, not educating yourself on the tell-tale signs of heart disease or a heart attack could be a matter of life or death—especially if you have any risk factors for coronary heart disease. Catching coronary heart disease early can prevent a heart attack, and catching a heart attack early could save your life.
The Difference Between Coronary Artery Disease and a Heart Attack
Coronary artery disease (also called coronary heart disease) is a chronic condition that can develop over many years. “When somebody has coronary artery disease, often times it’s actually a longstanding process, meaning years and years of not taking care of yourself, having high cholesterol, or having diabetes,” says Michelle Weisfelner Bloom, MD, a cardiologist at Stony Brook University Medical Center. Over time, cholesterol plaque builds up on the insides of the artery walls, which slowly starts to block blood flow in that artery. “At some point there’s not enough blood going through those arteries to supply the heart with enough blood. And that’s when patients start to develop symptoms of coronary artery disease,” says Dr. Bloom.
A heart attack occurs when that plaque buildup ruptures and forms a blood clot that blocks the artery. “If you have an occlusion of the artery, meaning it blocks it off, [you] have decreased blood flow to the area that the artery was providing blood supply, which is normally the muscle of the heart,” says Rachel Bond, MD, a cardiologist at Lenox Hill Hospital.
What Coronary Artery Disease Feels Like
Coronary heart disease is often called “silent CHD” because some people—especially women—have no symptoms at all. (Here’s more on how heart disease symptoms in women can be different.) When heart disease symptoms do present, a person might feel:
- Dull chest pain or discomfort (angina)
- Pain, discomfort, or numbness in the neck, abdomen, or back
- Shortness of breath
Often times this pain gets worse with physical activity or emotional stress, and gets better with rest.
A coronary artery disease symptom commonly missed is a sudden decline in your exercise tolerance, says Satjit Bhusri, MD, a cardiologist at Lenox Hill Hospital. “All of a sudden walking up a hill becomes more troublesome to you. You get more short of breath. Activities of daily living become more of a battle for you. [These] could be early signs of worsening coronary artery disease.”
What a Heart Attack Feels Like
Heart attack signs are similar to those of coronary artery disease, with a few key differences. When someone is having a heart attack, they might feel:
- Uncomfortable chest pain or pressure that lasts more than a few minutes, or goes away and comes back
- Pain or discomfort in one or both arms, the back, neck, jaw, or stomach
- Shortness of breath (with or without chest discomfort)
- Breaking out in a cold sweat
When you’re having a heart attack, symptoms tend to come out of nowhere. “Tightness or pressure comes on all of a sudden; you can be awakened from your sleep or just doing nothing,” says cardiologist Nieca Goldberg, MD, medical director at NYU Langone Health in New York. Whereas with coronary artery disease, symptoms are likely to have a trigger, like physical activity or stress. Symptoms of a heart attack also tend to get progressively worse.
If you’re feeling any symptoms of potential heart trouble (even if chest pain isn’t on the list), don’t wait to find out whether it’s heart disease or a heart attack. When you first experience chest tightness, shortness of breath, or notice that your exercise endurance has gone down, it’s important to seek medical attention right away, says Dr. Goldberg.
When it comes to your heart, the adage is true: It’s better to be safe, than sorry. Every minute matters—it can save your life.
00:00:00,000 --> 00:00:02,913
00:00:02,913 --> 00:00:07,316
The symptoms of coronary artery disease,
which is a chronic condition,
00:00:07,316 --> 00:00:11,434
meaning that you could have coronary
artery disease for a long time,
00:00:11,434 --> 00:00:14,790
versus the symptoms of a heart attack,
00:00:14,790 --> 00:00:20,243
00:00:20,243 --> 00:00:23,376
So when somebody has
coronary artery disease,
00:00:23,376 --> 00:00:26,912
oftentimes it's actually
a long standing process.
00:00:26,912 --> 00:00:31,979
Meaning over years and years of not taking
care of yourself, having high cholesterol,
00:00:31,979 --> 00:00:36,680
having diabetes, plaque builds up on
the inside of the walls of your arteries.
00:00:36,680 --> 00:00:41,080
And as you can imagine, as more and
more and more builds up, less and less and
00:00:41,080 --> 00:00:44,690
less of that tube to
the coronary artery is open.
00:00:44,690 --> 00:00:49,092
And at some point there's not enough blood
going through those arteries to supply
00:00:49,092 --> 00:00:50,696
the heart with enough blood.
00:00:50,696 --> 00:00:55,580
And that's when patients start to develop
symptoms of coronary artery disease.
00:00:55,580 --> 00:01:00,874
Symptoms of coronary artery disease
are tightness or pressure in the chest.
00:01:00,874 --> 00:01:02,390
It's a squeezing feeling.
00:01:02,390 --> 00:01:05,830
It can feel as though someone
is sitting on your chest.
00:01:05,830 --> 00:01:10,000
Commonly thought, as someone says,
an elephant is sitting on my chest.
00:01:10,000 --> 00:01:14,230
Fatigue, shortness of breath,
and of course, we see numbness and
00:01:14,230 --> 00:01:18,620
tingling down the left arm, or numbness
and tingling up the left side of the neck,
00:01:18,620 --> 00:01:20,170
or even the back.
00:01:20,170 --> 00:01:24,107
So during a heart attack there's
plaque, and that plaque builds up and
00:01:24,107 --> 00:01:25,427
00:01:25,427 --> 00:01:28,330
And when it ruptures a blood clot forms.
00:01:28,330 --> 00:01:31,520
And that blood clot can
actually occlude an artery.
00:01:31,520 --> 00:01:35,025
And if we have an occlusion of the artery,
meaning it blocks it off,
00:01:35,025 --> 00:01:38,960
we have decreased blood flow to that
area that the artery was providing blood
00:01:38,960 --> 00:01:41,682
supply, which is normally
the muscle of the heart.
00:01:41,682 --> 00:01:45,622
And that eventually leads to the symptoms
that the patients present with,
00:01:45,622 --> 00:01:50,061
such as chest pain or shortness of breath,
or they may feel nauseous or become very,
00:01:50,061 --> 00:01:51,720
00:01:51,720 --> 00:01:57,069
When you're having a heart attack,
the symptoms are maybe 100 fold worst.
00:01:58,270 --> 00:02:01,640
pressure comes on all of a sudden, and
00:02:01,640 --> 00:02:05,730
you can be awakened from your sleep or
just doing nothing.
00:02:05,730 --> 00:02:11,110
So it's important that when you first
experience either the chest tightness
00:02:11,110 --> 00:02:13,540
when you're walking or
get short of breath.
00:02:13,540 --> 00:02:18,360
Or notice that exercise endurance has just
gone down, you can't make it up a flight
00:02:18,360 --> 00:02:22,370
of stairs without resting,
then you need to seek medical attention.
00:02:22,370 --> 00:02:25,397
Call your doctor,
because then there's time for
00:02:25,397 --> 00:02:28,652
the doctor to do some tests
to evaluate the symptoms.
00:02:28,652 --> 00:02:33,429
