The implantation of a biventricular pacemaker is similar to that
of a standard pacemaker, but with a few twists. One of the wires
must stimulate a particular spot on the outside of the left
ventricle. Getting it there can sometimes be a challenge. If you
need a biventricular pacemaker, try to find a doctor who has
implanted many of them, and who is part of a team that offers
complete cardiovascular care.
If you would like to see how the procedure is done, you can watch

The definition of a myocardial infarction has been revised to
reflect the significance of a protein called troponin, which is
released into the bloodstream when heart muscle damaged.
One-third of people with heart failure have ventricles that beat
out of sync. A biventricular pacemaker sends electrical signals
to the ventricles to keep them working together, making everyday
Myocarditis is an inflammation of the middle layer of the heart.
It may be caused by a virus, allergic reaction, or exposure to a
toxin. Diagnosis is difficult because symptoms are not specific
and may suggest other causes.
A "polypill" containing multiple blood pressure medications, a

prevent heart disease.
Aspirin plus warfarin is an effective defense against
stroke-causing blood clots, but many people cannot take warfarin.
A study found that aspirin plus clopidogrel (Plavix) was also

A brief summary of research with potential future applications:
closing off the left atrial appendage to prevent clots,

new type of stent that dissolves over time.
I keep reading that peanut butter is a healthy food. But it contains saturated fat and has more sodium than potassium. That doesn't sound healthy to me.
I always thought that coronary and heart meant pretty much the
same thing. If that's so, isn't "coronary heart disease"
