Cardiovascular
diseases are number 1 killers
in both developed and developing
countries and with obesity now
becoming an epidemic these diseases
are taking the shape of an epidemic
too.All of us should keep us upto
date regarding news of cardiovascular
diseases as almost everyone is
effected by them or the loved
ones during some stage of life.So
here are the latest news regarding
cardiovascular diseases.

Being
heavy cuts angioplasty complications
Innumerable studies have laid
out the dire health consequences
of obesity, but there's one situation
where being overweight seems helpful:
coronary angioplasty.
Analysis of data from the New
York State Angioplasty Registry
indicates that people who are
moderately to severely obese are
less likely than others to suffer
major adverse events or to die
after undergoing catheter-balloon
procedures to open clogged coronary
arteries.
At the Weill Cornell Medical College
in New York, Dr. Robert M. Minutello
and colleagues studied the impact
of body mass index (BMI) -- a
measure of weight in relation
to height -- on in-hospital outcomes
after angioplasty by reviewing
data on more than 95,000 patients.
For the study, published in the
American Journal of Cardiology,
patients were classified according
to BMI as being underweight, healthy
weight, overweight, moderately
obese, severely obese, or very
severely obese.
The researchers report that a
U-shaped relationship was found
between body mass index and risk
of major adverse coronary events.
In-hospital deaths were higher
among underweight and very severely
obese patients than among the
others.
Furthermore, underweight and severely
obese patients were at greater
risk for the combination of death,
heart attack, or emergency surgery
than patients with moderate or
severe obesity.
Minutello's team suggests that
the poorer outcome in underweight
patients is not so surprising,
but the reasons why overweight
patients fare well is more puzzling.
One possibility is that these
patients may have larger blood
vessels, making the procedure
easier, but that is not proven.
All in all, the researchers call
for "further studies to determine
the factors responsible for the
evidently protective effect of
moderate and severe obesity."

Being
Downsized May Increase Stroke
Risk
Losing a job is always tough,
but for people nearing retirement
age, it may also be harmful to
their health, results of a new
study suggest.
People who lost a job close to
retirement age were more than
twice as likely to have a stroke
as people of the same age who
had not lost a job, researchers
report.
"Our study has established
that, for workers nearing retirement,
the loss of a job is a salient
experience associated with negative
effects on health, including increased
risk of stroke," Dr. William
T. Gallo at Yale University School
of Medicine in New Haven, Connecticut,
told Reuters Health.
"The public, in particular
older workers, physicians and
occupational health care providers
should be aware that involuntary
unemployment in the years leading
up to retirement may be a credible
risk factor for adverse health
events," Gallo said.
This is not the first time that
Gallo and his colleagues have
found that job loss can have a
negative impact on health.
Previously, the researchers reported
an association between job loss
and a decline in physical function
and an increase in symptoms of
depression, Gallo said. He also
noted that there is some evidence
of a link between job loss and
the development of depression
in a spouse, he said.
In the current study, Gallo and
his colleagues compared 457 workers
who lost their job with 3,763
people who were still working.
The average age of participants
in the study was 55.
During the 6-year study, people
who had lost a job were not more
likely to have a heart attack.
But the odds of having a stroke
were more than doubled in people
who had lost a job, even after
the researchers took into account
risk factors for stroke.
The study appears in the American
Journal of Industrial Medicine.
It was funded by the National
Institute on Aging and the Claude
D. Pepper Older Americans Independence
Center at Yale.
The study did not examine how
being laid off may increase the
risk of stroke, but Gallo and
his colleagues speculate that
losing a job close to retirement
age leads to stress, anxiety and
symptoms of depression, which
may increase the risk.
Gallo and his colleagues plan
to follow the participants for
several more years to measure
the long-term health effects of
job loss.

New
Heart Imaging Aids Patient Recovery
U.S. researchers have developed
a non-invasive heart imaging process
that could help develop better
therapies for recovering heart
attack patients.
Researchers at Yale University
School of Medicine have created
the new process by labeling radioactively
a protein present in newly-developing
blood vessels, which compose a
vital part of the healing process
after a heart attack.
Clinicians easily cab evaluate
the progression of blood vessel
growth by tracking the protein
using the imaging technology.
Previously, physicians had difficulty
gauging the efficacy of therapies
used to induce the growth of blood
vessels, because there was no
ability to evaluate the therapeutic
effects directly.
By taking multiple, timed images
of the heart, the researchers
were able to detect blood vessel
growth and track recovery of the
damaged area.

Sleep
Apnea Treatment Improves Heart
Risks
People who experience sleep apnea,
or brief episodes when breathing
stops, are often treated with
continuous positive airway pressure,
CPAP, to help them breathe properly
during the night. While rather
cumbersome and inconvenient, the
treat treatment is worth sticking
to -- especially for people who
have heart disease -- new findings
show.
According to a report in the European
Heart Journal, treatment of obstructive
sleep apnea reduces cardiovascular
events such as heart attacks or
the need for heart surgery among
people who already have coronary
heart disease.
Dr. Olivier Milleron from Ambroise
Pare Teaching Hospital in Paris,
France, and colleagues compared
rates of new cardiovascular events
over a five-year period in 25
patients with CAD whose sleep
apnea was treated and in 29 who
refused treatment.
CPAP was the treatment in 21 patients,
while 4 underwent upper airway
surgery.
Six treated patients (24 percent)
and 17 in the untreated group
(58 percent) had at least one
cardiovascular event during follow-up,
the authors report. Three heart-related
deaths that occurred were all
in the untreated group.
One of three treated patients
who discontinued CPAP after 18
months had a coronary 13 months
later, the researchers note, but
the other two remained free of
new cardiovascular events.
Dr. Milleron said he has found
these results useful in convincing
reluctant sleep apnea patients
to undergo CPAP.
"One third of coronary artery
disease patients have obstructive
sleep apnea," Milleron added.
"Moreover, sleep apnea is
associated with sleepiness, depression,
traffic accidents, and hypertension."
He urged doctors to be on the
lookout for the problem in their
heart patients. "If physicians
are not convinced that treating
sleep apnea is associated with
better outcomes in coronary artery
disease patients," Milleron
said, they should still offer
the treatment to such patients
"because it can give them
a better quality of life."
