Pericardial effusion is extra fluid around the heart.
Pericardial effusion is extra fluid inside the sac that surrounds the heart. The extra fluid causes pressure on the heart, which stops it from pumping blood normally. Lymph vessels may also be blocked, which often causes bacterial or viral infections. If fluid builds up quickly, a condition called cardiac tamponade may occur. In cardiac tamponade, the heart cannot pump enough blood to the rest of the body. This is life-threatening and must...
It also is possible that regular physical activity increases the
number of smaller blood vessels that connect different coronary arteries. If
one of the major coronary arteries is suddenly blocked, these collateral blood
vessels serve as an alternate route to supply blood to the portion of the heart
muscle threatened by a heart attack.
Exercise doesn't have to be difficult. Any
activity that raises your heart rate can be considered exercise, such as
walking, cycling, swimming, gardening, or dancing.
Try to do
moderate exercise at least 2½ hours a week. One way to
do this is to be active 30 minutes a day, at least 5 days a week. Or try to do
vigorous activity at least 1¼ hours a week.2 One way to
do this is to be active 25 minutes a day, at least 3 days a week. It's fine to
be active in blocks of 10 minutes or more throughout your day and week. You can
choose to do one or both types of activity. But if you have never exercised,
even 5 minutes of walking each day is a good start. Add more as you are
Talk to your doctor before you start an exercise program if
you have been diagnosed with coronary artery disease; have been sedentary for a
long period of time; or have other heart, lung, or metabolic diseases, such as
