Know the Difference: Heart Attack vs. Heart Failure

Heart disease is a major health risk. It’s the cause of one in four deaths in the U.S.

Since it’s such a big health risk, it’s helpful for everyone who has a heart to understand some of the more common heart ailments and the symptoms you may see in others, or yourself, if these disorders develop.

 

Coronary heart disease (also called coronary artery disease) — Coronary heart disease (CHD) tends to develop over time. A waxy substance called plaque can build up inside the arteries that provide blood to your heart muscle. This results in a narrowing of the small blood vessels providing blood and oxygen to the heart. This is sometimes called hardening of the arteries.

The reduced flow of blood and oxygen due to CHD can result in:

  • A squeezing feeling or pain in your chest or upper body. The pain may go away with rest or the medicine nitroglycerin.
  • Shortness of breath or fatigue after moderate activity.

Coronary heart disease can lead to a heart attack or heart failure.

 

Heart attack— When heart disease becomes severe, you can have a heart attack. This is when blood flow to the heart is cut off. Heart attacks usually happen suddenly. Without prompt heart attack treatment, the heart muscle begins to die.

The heart attack signs include:

  • Upper body pain. Women and men may feel chest pain or pain in the arms, back, neck or jaw.
  • Fatigue. This is common for women.
  • Shortness of breath.
  • Cold sweats.
  • Dizziness or nausea
  • Irregular heartbeat.

A heart attack is a medical emergency. If someone appears to be having a heart attack, call 911 or your local medical emergency number.

 

Heart failure(or congestive heart failure) — When a person’s heart function becomes weaker, the heart can’t pump enough blood to the body. This usually happens slowly over time. Your heart doesn’t stop working, but the weakened blood flow can cause:

  • Fatigue and shortness of breath.
  • Nausea or loss of appetite.
  • Blood and body fluids to back up into your lungs.
  • Swelling due to fluid buildup in your feet, ankles, legs, abdomen and veins in your neck. This buildup is called edema.

 

How Are These Heart Conditions Diagnosed?

Your cardiologist may request tests to diagnose the cause of your heart problems. The tests may include blood tests, an EKG that tracks your heartbeats or imaging or scans such as an X-ray or ultrasound. The test results will help your clinician recommend treatment, which may include:

  • Medications — Your clinician can choose from a number of drug therapies to help improve your heart health.
  • Angioplasty and stents are used to treat patients with heart attack or blockages in their coronary arteries to restore blood flow to the heart.
  • In more severe cases, coronary artery bypass surgery may be recommended.
  • Monitoring — A system such as CardioMEMS sends your clinician data about your heart’s performance. The information allows your clinician to fine tune your medications and improve your quality of life!
  

If these approaches don’t help, your clinician can discuss other options, such as a special implanted pacemaker or heart assisting pump.

If heart failure becomes advanced, you may be considered for a heart transplant.
