Never miss a heart beat

Local

September is Atrial Fibrillation awareness month. This morning Steve sat down with Dr. Susan Kemp, chief of staff elect at Christus Health, to help explain this complex condition.

What is it?

AFib is caused when the two upper chambers of the heart beat unpredictably and sometimes rapidly. These irregular heartbeats can cause blood to collect in the heart and potentially form a clot, which can travel to a person’s brain and cause a stroke. While AFib can occur at any age, it is more common in people 65 years and older. AFib is more common in people with high blood pressure, heart disease, or diabetes.

Why it matters?

AFib itself is not life threatening. However, AFib can cause blood clots. Normally, blood clots are a good thing. It’s your body’s way of protecting you from bleeding too much if you are injured. If you have AFib, you are five times more likely to have a stroke. Furthermore, AFib-related strokes are nearly twice as likely to be fatal or severely disabling as strokes not associated with AFib.

AFib Symptoms

Sometimes people with AFib will not have any symptoms. This is known as silent AFib and can only be detected during a physical. However, others can experience one or more of the following symptoms:

  • General tiredness or weakness
  • Rapid and irregular heart beat
  • Fluttering in the chest
  • Dizziness or lightheadedness
  • Anxiety or confusion
  • Shortness of breath
  • Chest pain or pressure
  • Low blood pressure

Risk Factors for AFib

If you have AFib, you are not alone. About 2.7 million people in the U.S. have AFib. Many people with AFib also have one or more other health problems, such as those listed here. These other medical conditions or factors increase your risk for AFib and make managing AFib more difficult. 

  • Age (AFib is more common among people 65 and older; about 11% of people over 80 have AFib)
  • Family history (an increased risk occurs in some families)
  • Gender (women are at greater risk than men)
  • High blood pressure
  • Some chronic conditions (diabetes, sleep apnea, thyroid problems, metabolic syndrome,  chronic kidney disease or lung disease)
  • Heart disease (anyone with heart valve problems, congenital heart disease, congestive heart failure, coronary artery disease, or a history of heart attack or heart surgery)
  • Stimulant use (such as medications, caffeine, tobacco, alcohol)
  • Obesity
