If you have had a problem taking a medication, or a medical device
has caused you harm, tell the FDA about it. The more information
the FDA has about so-called adverse reactions the better. This

Your body needs calcium to build bones, contract muscles, send
nerve signals, help enzymes and genes do their jobs, and much
more — including making your heart beat. Some time in middle age,
calcium seems to start moving from bones to the cardiovascular
system, where it stiffens arteries and heart valves. A report

Almost 25% of smokers smoke only a few cigarettes per day, or smoke only once in a while, but they are still exposing themselves to the same health risks as heavier smokers.

Many claims have been made about the ability of resveratrol to

Yoga's combination of gentle exercise, stretching, focus on deep
breathing, and the resulting greater mindfulness may be of
particular benefit to people living with cardiovascular disease.
The Food and Drug Administration has established a toll-free

A trial of the antidepressant sertraline in people living with
heart failure did not ease their depression.
Researchers have concluded that caffeine does not affect the

I avoid grapefruit juice because my doctor says it affects how my
body handles the Lipitor I take for my cholesterol. Should I also
stay away from pomelo?
I am an 84-year-old man with atrial fibrillation, mild heart
failure, and high blood pressure. My doctor had me wear a Holter
monitor and get a SPECT scan. Now he wants me to have a cardiac
MRI. What info would this test give that he doesn't already have?
I'm a 79-year-old man with atrial fibrillation on Pacerone. I
also take warfarin and aspirin. I plan to have a tooth pulled
next month and wonder if it is safe to go off the blood thinners.
How are these medications handled when serious surgery is needed?
Many people in my neighborhood heat their homes with wood stoves.
The smoke really bothers me. Does what's coming out of their
