Some researchers at Johns Hopkins think those popular caffeinated drinks deserve a warning label.

According to a New York Times article, "the caffeine content of energy drinks varies from 50 milligrams to more than 500 milligrams per serving. A regular 12-ounce cola drink has about 35 milligrams of caffeine, and a 6-ounce cup of brewed coffee has 80 to 150 milligrams of caffeine.

Some energy drinks contain the caffeine equivalent of 14 cans of Coca-Cola, said Roland Griffiths, a professor of behavioral biology and one of the study authors."

Tomorrow I'm going to meet a new doctor to look at my heart.

I've got an arrhythmia problem, it feels like it's getting worst, I've got a procedure coming and I scheduled an appointment with a doctor that came highly recommended.

My appointment to meet this doctor was really scheduled for last month. After sitting in a private patient room for 30 minutes waiting, the nurse came in and said the doctor is running behind and should be here shortly. So I laid down on the thin white paper and closed my eyes.

Some experts say the first line of defense for kids when battling obesity should be exercise and nutritional counseling. Others say that plan of action may not be aggressive enough. What do you think?

For years, I've had blood pressure that usually hovers in the area of 98/68. I'm not on any medications and exercise five days a week. A relative said that may be a sign of a thyroid condition. Is that true? Can blood pressure be too low?

Anyone know of alternative options to treating atrial fibrillation? Typical drugs can affect liver and kidneys with long-term use. And what if this condition is further complicated by the existence of moderate mitral stenosis?

I'm 45 yr old female, 160 lbs, 5'1. Trying to loose weight and have chronic fatigue.

I started walking and I notice 20 mins in to my walk, I get chest pain on the upper right side of my chest. The decollete area, in between my collarbone and the beginning of my breast. The pain is sharp heavy but does not spread. It starts gradually but goes away if I rest. Is this a sign of a Heart Attack or Angina?

My mother feels everyone doesn't believe her symptoms anymore after being
examined thoroughly in ER. I am visiting with her heart surgeon next week
and I need to discuss her issues with him. Can you please help?

My friend has had some cardiac complications and atrial fibrillation for a few years. She is 77 years old and she is looking to get a second opinion about her condition.

My parents use a butter spread that claims to "actively remove cholesterol". I've noticed several types of butter/oil spreads at the grocery store, meant to replace butter or margarine, and are touted as "healthy alternatives".

However, one brand says that it is "clinically proven to actively remove cholesterol". Is this true, and to what degree? Is this butter spread actually healthy (use some every day) or is it just a healthy alternative (no trans-fat like butter).

I was just diagnosed with Atrial Fibrillation and I'm really freaking out. Could you help me find information on it? I left my doctor's office really confused.

Thanks so much for your help!
