Women & Heart Disease Across the Lifespan (Part 3): Older Women

07/16/2010

During this final installment of our 3 part series about women and heart disease we will be focusing on heart problems older women are more likely to experience. Some of the things we will discuss are heart failure, diastolic dysfunction, atrial fibrillation, aortic valve disease and sudden cardiac death.

Is Diabetes a Risk Factor for Atrial Fibrillation (AF)?

10/12/2009

For the first time diabetes has been shown to be an independent risk factor for AF according to a study published in the October 2009 issue of Diabetes Care. While there is an increased risk of AF in men with diabetes, there is a stronger association between diabetes and AF in women.  Diabetes is an even stronger risk factor than obesity and high blood pressure in women.  Normally, AF occurs more in men than women.  This study showed that women with diabetes had the same incidence of AF as men without diabetes.

While the actual reason behind this relationship is not understood, there is a theory.  Diabetes is known to cause damage to nerves, called neuropathies, and it is possible that the diabetes causes a type of neuropathy in the heart, which can lead to irregular heart rhythms.

 The bottom line is that it is important for diabetic patients to see their healthcare provider regularly and to be evaluated for any type of palpitations.

“Take Charge: A Woman’s Guide to a Healthier Heart” discusses how women can help control their cholesterol and other risk factors to prevent a heart attack, stroke and diabetes. “Take Charge: A Man’s Roadmap to a Healthier Heart” is due to be released Fall 2009.

Catheter Ablation Study for Atrial Fibrillation Yields Mixed Results

08/23/2009

afib ablation

Most people who develop atrial fibrillation are first treated with medications, but medicine only works for about 50% of patients. So then what are your options?

Catheter ablation is a relatively new procedure that may help people with atrial fibrillation.  Catheter ablation is a minimally invasive procedure.  Small thin flexible catheters are passed through blood vessels to reach the heart and then deliver electrical energy that ablates (destroys) abnormal electrical tissue in the heart that is causing the abnormal heart rhythm. 

The Department of Health & Human Services and Agency for Healthcare Research and Quality recently released a report evaluating the benefits of catheter ablation procedures for people with atrial fibrillation.  The report can be found at http://www.effectivehealthcare.ahrq.gov

The report summary states that catheter ablation may “hold promise for treating atrial fibrillation” but more research is needed on this procedure, especially in women, the elderly and people with heart failure or high blood pressure.  The report found that catheter ablation has been shown to help maintain a normal heart rhythm over short periods of time (up to 1 year) but there is little evidence to show long term benefit.  Also there is no data to prove the effectiveness of catheter ablation as a first line therapy, before trialing medications to control the irregular heart rhythm.  The FDA also stated that there is no conclusive evidence of a lower stroke risk in people who undergo catheter ablation.  So patients at risk for a stroke should continue taking preventative blood-thinning medications.

Further studies are ongoing and this may be a treatment to consider in patients with atrial fibrillation but the indications and benefits should be discussed on an individual basis with your heart specialist.

Atrial Fibrillation Research Study Seeks Afib Patients near San Francisco, Cincinnati, and New Jersey

06/29/2009

 An afib research study is looking for volunteers that meet the following criteria: Between 21 and 65 years of age Have taken one of the following medications: Flecainide Rythmol (IR or SR) Propafenone Moricizine Encainide Lorcainide Live in or near: Edison, NJ — includes central/northern New Jersey and New York Cincinnati, OH and surrounding areas San Francisco, CA and the Bay area.

If you’re qualified and participate in a one-on-one interview or a small focus group with other afib patients, you will receive $100 to $125 for your time. You will be asked a few additional questions to ensure you meet the study criteria. If you meet the criteria above and would like to apply, please contact us using this Contact Form (http://stopafib.org/contact.cfm) so we can connect you with the study organizers. Please include your contact info (phone, e-mail, and mailing address). Thanks for your help.

By participating, you will help future afibbers.

Atrial Fibrillation More Common Among Whites

06/13/2009

 

Atrial fibrillation is one of the most common heart arrhythmias in the United States.  Atrial fibrillation is an irregular heart rhythm that causes the top chambers of the heart to quiver and fire at a very rapid rate – decreasing the effectiveness of the heart to pump.  About 2 million adults in the United States have atrial fibrillation which is a very strong risk factor for stroke.

A recent study presented at the Heart Rhythm Society’s annual meeting revealed that atrial fibrillation is more common in whites than blacks/African Americans.   Over 200,000 patients were evaluated.  High blood pressure and diabetes are important risk factors that can lead to the development of atrial fibrillation, both of which are more common in blacks.  This study proves that ethnicity plays an important role in the incidence of atrial fibrillation.

Atrial fibrillation symptoms can vary from person to person.  Some people have no symptoms.

The most common symptom in people with intermittent atrial fibrillation is palplitations, a sensation of rapid or irregular heartbeat.  Often described as an irregular fluttering sensation in the chest.

Some people become light-headed or faint.

Other symptoms include weakness, lack of energy or shortness of breath with effort, and chest pain.
