Did you know that a heart attack happens once every 20 seconds? And, that someone dies of an MI every minute of every day? Because cardiac disease is the single most common cause of death in the US, every nursing assistant must have armed with basic information about heart attacks. The more they know, the sooner they will be able to respond when faced with a cardiac emergency. Feel free to share this information with the CNAs at your workplace:
Heart Attacks & the Heart
Have you heard of a "myocardial infarction" or "MI" for short? It means "death of the heart muscle" and is the medical term for a heart attack. For many years, people thought that heart disease was a "man's disease". But now we know that plenty of women have heart attacks, too!
The heart is a hard working machine-and probably the most important muscle of the entire body. The heart's job is to pump blood and oxygen to every part of the body.
For the heart to pump, it needs a huge amount of oxygen of its own. So, to keep the body going, the heart "feeds" itself first. The rest of the body gets the leftover oxygen.
An MI happens when oxygen can not get to one part of the heart because of a blockage in a heart blood vessel. This blockage may be temporary or permanent, but, either way, it prevails oxygen from getting to the heart. The heart muscle gets so "starved" for oxygen that it becomes damaged or even dies.
It's very important to learn about the risk factors and the warning signs of an MI so that you can help your clients- before, during, and after a heart attack.
And, remember … what people do not know about their hearts can kill them!
What Happens During a Myocardial Infarction?
An MI happens when one of the heart's blood vessels becomes blocked by a blood clot or a buildup of fat. The blockage keeps blood and oxygen from getting to the heart, and the heart tissue begins to die.
Usually, a heart attack causes chest pains called angina. The pain is severe during the attack-usually lasting 15 minutes or more-and angina medication does not help.
If an MI is mild, only a small area of the heart is affected. If it's severe, a large area is affected and may be permanently damaged. The victim may die.
Remember, sometimes there are no symptoms and victims do not even know they have heart disease. These attacks are silent killers known as sudden cardiac death (SCD) or cardiac arrest. They happen instantly or right after the warning signs start.
Heart Attack Warning Signs!
According to the American Heart Association, the following are common warning signs of a myocardial infarction:
- Uncomfortable pressure, fullness, squeezing or pain in the center of the chest-the pain lasts more than a few minutes or may go away and come back.
- Pain spreading to the shoulders, neck or arms.
- Lightheadedness, falseing, sweating, nausea, or shortness of breath.
- Other warning signs that are not as common include:
- Unusual stomach or abdominal pain.
- Nausea or dizziness.
- Shortness of breath and difficulty breathing.
- Unexplained anxiety, weakness or fatigue.
- Palpitations (a racing heart), cold sweat or paleness.
Heart attack victims have described their "discomfort" as "pressure in the chest," "a feeling of weakness," "a feeling of indigestion" or "having a touch of the flu." But, remember that not everyone has all the warning signs and / or all of the symptoms of a heart attack. Sometimes there are not any symptoms and the attack kills with no warning at all!
To make things even more difficult, the symptoms of a myocardial infarction are not always clear cut. People tend to brush them off as minor problems such as heartburn or the "flu". Denial is a common symptom of an MI. And, denial can be deadly. It follows people from getting the help they need.
Keep in mind that doctors can do the most good in the first hour after the heart attack. So, if you think someone is having a heart attack, get help or call 911 right away!
Tips for Helping Clients After a Heart Attack
- Remind your clients to take their medications ON TIME! Heart medications help the heart and blood vessels work better. If they are not taken on schedule, they will not work as well.
- Be alert! Depression is very common in heart attack survivors. It can be mild or serious and may last several months. But, if a client is depressed all the time, it can be hard on the heart. Watch your clients for the signs of depression and report any changes to your supervisor.
- Be reassuring! After a heart attack, your clients may be afraid of being alone or of doing any kind of exercise / activity at all.
- Be supportive! Most people who recover from heart attacks have to change their eating habits-especially if they are overweight, have high cholesterol or high blood pressure.
- Encourage your clients to give up smoking! Remember … a person is never too old to kick the habit.
