The Institute of Medicine's newly released
report, Strategies to Reduce Sodium Intake in the United
States, focuses on big-picture strategies for reining in
America's salt habit. Although the report's recommendations
represent an essential step forward, there are many things that
individuals, chefs, and organizations can do right now to reduce
sodium. Many of these guidelines offer a "stealth health"
approach to sodium reduction — ways that sodium can be reduced
with no change or minimal change to consumer food experiences or
choices. Others suggest ways to rebalance and re-imagine food
choices as well as introduce new foods that can easily translate
into satisfying meals.
Hot, humid weather can overwork the heart, which can pose risks
for people with certain conditions, or those who take beta
blockers or diuretics.
Postprandial hypotension, low blood pressure that occurs after eating, can cause dizziness, chest pain, nausea, or other issues, particularly in the elderly. If you often feel odd after eating, tell your doctor. He or she can work with you to see if the feelings are due to postprandial hypotension or something else, and help you find ways to ease the problem.
The average person consumes more salt each day than the body
requires, most of it from "hidden" salt in prepared and packaged
foods. The FDA may ask food companies to voluntarily reduce the
salt content of their products over the coming decade.
If the mitral valve in the heart becomes damaged it can leak,
causing blood to flow backward and overwork the heart. A leaky
valve can be surgically replaced, but in some situations
repairing the valve is more effective than surgery. The repair
operation has a lower rate of death (one to two per 100
operations) than valve replacement (four to six per 100), causes
fewer strokes, is more effective at reducing symptoms of mitral
regurgitation, has a shorter recovery time, and is associated
with fewer postoperative heart rhythm problems. Long-term studies
show low rates of reoperation. Repaired valves don't wear out, as
biological valves do, nor do they need anticoagulation, as
mechanical valves do. But they can fail over time due to
progression of the disease that caused the regurgitation in the
Researchers found that when people having conversations with
their doctors about impending bypass surgery were given a
recording of the consultation, they had a better understanding of
The FDA has approved the sale of a generic version of the
angiotensin-receptor blocker medication losartan, and generic
versions of two other ARBs may soon follow.

After I had an abnormal electrocardiogram, my doctor wants me to
have a nuclear stress test to check my arteries for any
blockages. (I also have a left side bundle block.) What
noninvasive test would give as much information (or almost as
much) as a nuclear stress test? I have had many scans, for this
and that, so I would like to limit my exposure to radiation if
I have rheumatoid arthritis, and my doctor wants me to take
prednisone for it. Will this drug be bad for my blood pressure,
which is already high?
A year ago, I had an orchiectomy for prostate cancer; my PSA is
now 0.74. Not long afterward, I had two cardiac stents implanted.
I still have some angina and shortness of breath. I started
Ranexa a couple of weeks ago, which helps my angina. Do you have
any suggestions for my heart since I no longer make testosterone,
which I understand helps protect men’s hearts and arteries?
