What is AFib?

Are you aged 65 or older and you find yourself out of breath, even when you haven’t been moving? You may be suffering from atrial fibrillation (AFib), a type of arrhythmia or irregular heartbeat.

An AFib Attack

During an AFib attack, the electrical signals that tell your heart to start beating becomes out of order. This malfunction affects two upper chambers of the heart (called atria) and causes them to quiver. It also disrupts the blood flow into the lower chambers of the heart or the ventricles, and causes them to contract faster or beat in an irregular manner. Because of this, the ventricles may not be able to pump blood to the rest of your body as it should.

The trembling in your atria may lead to blood pooling which may further cause blood clots. These blood clots may pump out of the heart, go to the brain and cause blockages which may then lead to a stroke.

What Are the Symptoms of AFib?

  • Quivering or fluttering heartbeat
  • Irregular heartbeat
  • Anxiety
  • Chest pain
  • Dizziness
  • Fainting or confusion
  • Fatigue
  • Shortness of breath
  • Sweating
  • Weakness

The Causes of AFib

Common conditions that lead to AFib are:

  • Congestive heart failure
  • Coronary artery disease
  • Heart valve disease
  • High blood pressure
  • Hypertrophic cardiomyopathy
  • Overactive thyroid gland
  • Pericarditis (inflammation of the covering of the heart)
  • Thyroid disease
  • Heart surgery, taking certain medications and binge drinking may also lead to AFib.

What Are the Treatment Options for AFib?

  • Medications for heart rate and rhythm
  • Blood thinners that can prevent blood clots and thus reduce risk of stroke
  • Electrophysiology treatments such as pacemaker placement or ablation
  • Lifestyle changes (i.e., consuming a healthier diet and exercising regularly)

How Can You Reduce Your Risk for AFib?

  • Consuming a heart-healthy diet
  • Maintaining a healthy weight
  • Exercising regularly
  • Managing your blood pressure
  • Managing stress
  • Avoiding smoking
  • Limiting your alcohol and caffeine intake

Know Your Numbers

Over the years you have probably memorized a lot of numbers – Your home phone number, cell number, social security number, home address, and maybe even your driver’s license number or bank account. While these numbers are important, so are a few more that can tell you how healthy you are or if you need treatment for certain medical conditions.

You should know what your blood pressure is because high blood pressure, which has no symptoms, can cause serious problems such as stroke, heart failure, heart attack or kidney failure. Normal blood pressure should be 119/79 or lower. A reading of 140/90 or above is a sign of high blood pressure. High blood pressure can be controlled by making healthy lifestyle choices and taking medications if necessary.

You can find out if your current weight is healthy by calculating your body mass index, or BMI, which is a measurement of body fat based on height and weight. A BMI of less than 18.5 is considered to be underweight; normal is 18.5 to 24.9; overweight is 25 to 29.9; and 30 or higher is considered obese. Obesity can increase the risk for certain cancers, depression, gallbladder and heart disease, high blood pressure, osteoarthritis, sleep apnea, stroke and type 2 diabetes. Even a modest weight loss of 10 percent of your current weight can help lower your risk for developing diseases associated with obesity.

Triglycerides are a kind of fat found in your blood that your body uses for energy. An elevated triglyceride level can increase the risk for heart disease. Normal triglyceride levels are: less than 150 mg/dL; borderline-high, 150 to 199 mg/dL; high, 200 to 499 mg/dL; and very high, 500 mg/dL or higher. High triglycerides usually don’t cause symptoms but can be lowered through diet and lifestyle changes.

Cholesterol is a waxy substance that is produced by the liver and found in certain foods. Elevated cholesterol can lead to narrowing of the arteries due to plaque buildup and cause chest pain, heart attack or stroke. Total cholesterol level should be less than 200 mg/dL. A total cholesterol that is 200 to 239 mg/dL is borderline high; 240 mg/dL and above is considered high. Cholesterol can be lowered through lifestyle changes and medications.

The sugar that the body uses for energy is called glucose. Elevated glucose levels can indicate diabetes, a chronic disease that occurs when the body fails to process sugar correctly. Normal results for a 75-gram oral glucose tolerance test would show a fasting level of 60 to 100 mg/dL, a one-hour level of less than 200 mg/dL, and a two-hour level of less than 140 mg/dL. A two-hour level of 140 to 200 mg/dL would indicate pre-diabetes, and a level over 200 mg/dL would be a sign of diabetes.

Heart Disease is the No. 1 Killer of Women

You may know that heart disease is the No. 1 killer of men and women in the U.S. So, what is different for women?

  1. One in three women will develop heart disease in their lifetime.
  2. More women die of coronary heart disease than men, and fewer women survive a first heart attack.
  3. Ninety percent of women have at least one risk factor for heart disease or stroke. Healthy lifestyle choices can make a positive difference.
  4. Risks for heart disease increase with age, especially after menopause, but can actually happen at any age, such as with pregnancy-related complications or many ovarian cysts.
  5. Heart attack symptoms can be as subtle as arm, neck, jaw or back pain, shortness of breath, nausea/vomiting or dizziness/lightheadedness.
  6. Women are less likely to receive guideline-recommended therapies, such as aspirin, and less likely to have interventions such as stenting. Talk with your doctor about heart disease.

Take care of yourself by not ignoring symptoms, getting an annual screening/checkup and asking questions about your heart health.

Smoking and Heart Disease

A cigarette is about five inches long and less than half an inch in diameter. You might think that something so small might be harmless. But tobacco smoke contains more than 7,000 chemicals, including 250 that are known to be harmful, such as hydrogen cyanide, arsenic, benzene, chromium, and vinyl chloride. Smoking causes many different types of cancer, as well as chronic bronchitis, emphysema, diabetes, cataracts and heart disease.

People who smoke are up to six times more likely to have a heart attack compared to nonsmokers and have a greater risk of experiencing a major heart problem at least 10 years before their nonsmoking counterparts. Cigarette smokers also have a higher chance of developing atherosclerosis, the slow buildup of plaque that hardens and narrows the arteries. In addition, they may develop coronary artery disease that can lead to chest pain, heart attack, heart failure, arrhythmia (irregular heartbeat) or death.

Chemicals in tobacco smoke not only damage blood cells, but also affect how the heart works and the function and structure of blood vessels. For example, nicotine can elevate blood pressure and make blood clots form more easily.

Smokers aren’t the only ones at risk for heart disease from tobacco smoke. The heart and blood vessels also are affected by secondhand smoke, which comes from the smoke exhaled by a smoker or the burning end of a cigarette, cigar or pipe. According to the American Heart Association, each year approximately 22,700 to 69,600 premature deaths are due to heart and blood vessel diseases caused by environmental tobacco smoke. This type of smoke also increases the coronary heart disease risk for children and teens because it lowers HDL cholesterol, hurts heart tissue and elevates blood pressure.

Stopping smoking isn’t easy. But quitting reduces the risk of heart disease right away and the benefits of being smoke-free increase over time. Heart rate and blood pressure begin to return to normal immediately and within hours the carbon monoxide level in the blood starts to decrease. A few weeks later circulation improves, and there is less coughing and wheezing. Lung function increases in a few months and by one year after quitting the chances of developing heart disease drop by more than 50 percent. After several years, the risk will be near that of someone who has never smoked.

Regardless of how long, how often, or how much you have smoked, quitting will help. Even if you already have heart disease, not smoking can lower your risk of another heart attack, other chronic diseases or death. For people undergoing surgery, chemotherapy or other treatments, quitting can help improve the body’s ability to heal and respond to therapy.

Heart Attacks in Winter

Winter means cooler temperatures and the holiday season, but did you know it also brings an increased risk of heart attack?  Studies show the risk of dying from a heart attack is greater in the winter than at any other time of year, with cardiac mortality at its highest in December and January. While the reasons for the increase in heart attacks are complex – including changes in hormone, stress and exertion levels – you can take steps to reduce your risk.

There are several reasons heart attacks are more frequent in winter.  First, during the winter months, changes in hormonal balances put individuals at greater risk for cardiovascular problems.  In addition, the colder temperatures cause arteries to tighten, restricting blood flow, reducing oxygen to the heart and causing blood pressure to increase, all of which can set the stage for a heart attack, especially in plaque-clogged arteries.  During winter months people tend to exercise and do yard work and other physical activity earlier in the day.  Since blood pressure rises naturally in the morning, increased exertion early in the day can contribute to heart attacks.  The flu season also may play a role in the increased number of heart attacks. The influenza virus may trigger inflammation of the heart, which may cause a heart attack.

The holidays may play a role in the increased number of heart attacks. People overindulge in food and alcohol, which often leads to weight gain and contributes to the risk for heart attack.  Alcohol has its own heart risks, increasing blood pressure, contributing to abnormal heart rhythms and increasing the risk of depression.  The hustle and bustle of the holiday season can also be a source of stress, with many people pressed for time and money.  Anxiety and depression tend to increase during this time of year, further increasing the risk of heart attack.

Though there are several reasons heart attacks are more common in winter, you can take steps to reduce your risk. First, avoid over-exertion and talk to your doctor about appropriate physical activity.  Winter chores such as shoveling snow can be particularly strenuous.  If you must shovel snow, take frequent breaks and be sure to bundle up and stay warm.  Experts recommend dressing in three layers: an inner layer that wicks away moisture, a middle layer that insulates the body and a top layer that repels rain and water.  If you are over 50 or have a history of health problems, get someone to shovel the snow for you.  If you are sore after shoveling snow, take symptoms seriously, as signs of a heart attack may be mistaken for a pulled muscle.

The holidays provide ample opportunities to eat and drink, but try to do so in moderation.  Avoid caffeine and nicotine, both of which can exacerbate heart problems, and consider taking at least 400 IU (international units) of vitamin D each day.  Low levels of vitamin D have been found more often in heart attack patients.  Finally, be sure to get your flu shot, which can cut your risk of heart attack in half.

In any season, the best medicine to ward off heart attacks is prevention: Cultivate heart-healthy habits, such as regular exercise, weight control, and a diet rich in fiber, fruits and vegetables.  Also, know your cholesterol, blood pressure and blood sugar levels.  Finally, to combat the holiday blues, take solace in the company of friends and loved ones.

How can I prevent a heart attack?

This is a question I am asked frequently, not only from patients, but also from friends and family. Cardiovascular disease mortality has dropped dramatically in the past 25 years, but still remains the leading cause of death in the U.S. What many people may not realize is that over 80% of heart attacks are PREVENTABLE! Yep, that’s right. Our diet and lifestyle choices dramatically affect our chances of developing heart disease. While genetics certainly play a role in our susceptibility to heart disease (and we still are in the infancy of understanding these genetics), this is felt to play a minor role in causality. You can play a MAJOR part in prevention.

Let’s list what you can do:

1. If you smoke, stop. Smoking increases your risk of having a heart attack by about 30%, and stopping smoking is the main preventive thing you can do. There are medications and counseling available that may help you quit.

2. Diet is important. In the the 1950’s, Japan had a low incidence of heart disease. But starting in the 1960’s, this started to change significantly. What happened? McDonalds and other fast food outlets moved in, and the typical Japanese diet of fish, rice and vegetables started to change to a high fat, high calorie Western diet. Coincidence? Unlikely. What has been shown is that a Mediterranean type diet of fresh fruit and vegetables, fish, and nuts does lower risk. The South Beach Diet was written by a cardiologist and is a good resource for healthy eating that I frequently recommend. Does that mean you have to completely give up mac and cheese or fried chicken? No, but when given a choice, maybe go with the healthier alternative on a regular basis, and save those for weekends or holidays.

3. Maintain a reasonable weight. I know, it’s hard. But being overweight is tied to increased risk of high blood pressure, higher cholesterol and diabetes, which are all risk factors for heart attacks.

4. Regular exercise. I’m not asking you to run the Mercedes Marathon. Simply walking for 30 minutes five days a week lowers risk by 25-30%. If you want to do more, that’s great!

5. “Hey, Doc…I take an aspirin every day. I should be good”. Not so fast. Aspirin is certainly good for those with a history of cardiovascular disease (heart attack, stroke, etc.), but several large recent studies show that it has little benefit for primary prevention, and actually may be harmful, since it increases bleeding risk.

6. How about statins (cholesterol lowering drugs) like Lipitor? Should we just put them in the drinking water? Absolutely not. The benefits really depend on your baseline risk, such as diabetes, high blood pressure, and your cholesterol levels. Doctors now even have computer programs that can quickly give us the risk/benefit levels of starting these medications that can be discussed during your office visit.

To sum things up, an ounce of prevention is at least worth a pound of cure when it comes to heart disease. Get off the couch, eat better, and quit smoking. It can make a difference!
