Conclusion
The Levitronix
®
CentriMag VAD was able to temporarily provide
satisfactory mechanical circulatory support in acute decompensated
heart failure. It can provide better circulatory support than ECMO.
Additionally, it is easy to set up and repair without causing
considerable damage to the myocardium if a bridge to recovery
is expected. In this case, the Levitronix
®
CentriMag VAD was
successfully implemented to save the life of a young patient who
had experienced hypokalaemia-related cardiac arrest resulting from
iatrogenic insulin infusion.

‘Robust study’ endorses link between red/processed meats and
cardiovascular disease
E
ating two servings of red meat,
processed meat or poultry, but not
fish, per week was linked to a 3–7%
higher risk of cardiovascular disease and a
3% higher risk of all causes of death, the
study found.
‘It’s a small difference, but it’s worth
trying to reduce red meat and processed
meat like pepperoni, bologna and deli
meats,’ said senior study author Norrina
Allen, associate professor of preventive
medicine at Northwestern University
Feinberg School of Medicine. ‘Red meat
consumption also is consistently linked to
other health problems like cancer.’
‘Modifying intake of these animal protein
foods may be an important strategy to help
reduce the risk of cardiovascular disease
and premature death at a population
level,’ said lead study author Victor Zhong,
assistant professor of nutritional sciences
at Cornell University, who did the research
when he was a postdoctoral fellow in
Allen’s laboratory.
The findings come on the heels of a
controversial meta-analysis published last
November that recommended people
not reduce the amount of red meat
and processed meat they eat. ‘Everyone
interpreted that it was OK to eat red meat,
but I don’t think that is what the science
supports,’ Allen said. ‘Our study shows
the link to cardiovascular disease and
mortality was robust,’ Zhong said.
‘Fish, seafood and plant-based
sources of protein such as nuts and
legumes, including beans and peas, are
excellent alternatives to meat and are
under-consumed in the US,’ said study
co-author Linda van Horn, professor of
preventive medicine at Feinberg who
also is a member of the 2020 US Dietary
Guidelines Advisory committee.
The study found a positive association
between poultry intake and cardiovascular
disease, but the evidence so far isn’t
sufficient to make a clear recommendation
about poultry intake, Zhong said. Still,
fried chicken is not recommended.
The study pooled together a large
diverse sample from six cohorts, included
long follow-up data of up to three
decades, harmonised diet data to reduce
heterogeneity, adjusted a comprehensive
set of confounders and conducted multiple
sensitivity analyses. The study included 29
682 participants (mean age of 53.7 years
at baseline, 44.4% men and 30.7% non-
white). Diet data were self-reported by
participants, who were asked a long list
of what they ate for the previous year or
month.
Key findings: a 3–7% higher risk of
cardiovascular disease and premature
death for people who ate two servings a
week of red meat and processed meat; a
4% higher risk of cardiovascular disease
for people who ate two servings per week
of poultry, but the evidence so far is not
sufficient to make a clear recommendation
about poultry intake and the relationship
may be related to the method of cooking
the chicken and consumption of the skin
rather than the chicken meat itself; and
no association between eating fish and
cardiovascular disease or mortality.
‘Limitations of the study are
participants’ dietary intake was assessed
once, and dietary behaviours may have
changed over time. In addition, cooking
methods were not considered. Fried
chicken, especially deep fat-fried sources
that contribute trans fatty acids, and fried
fish intake have been positively linked to
chronic diseases,’ Zhong said.
The study was funded by National
Institutes of Health/National Heart, Lung,
and Blood Institute (R21 HL085375),
American Heart Association Strategically
Focused Research Networks and the
Feinberg School of Medicine.
