Current methods to predict the risk of myocardial infarction (MI) and
stroke vastly underestimate the risk in individuals with HIV, which is
nearly double that of the general population, according to a study
published online by JAMA Cardiology.
“The actual risk of heart attack for people with HIV was roughly 50%
higher than predicted by the risk calculator many physicians use for the
general population,” said Matthew Feinstein, MD, Northwestern
University Feinberg School of Medicine, Chicago, Illinois.
The higher risk for MI -- about 1.5 to 2 times greater -- exists even
in people whose virus is undetectable in their blood because of
antiretroviral drugs.
Accurately predicting an individual’s risk helps determine whether he
or she should take medications such as statins to reduce the risk of MI
or stroke.
“If you have a higher risk for heart attack or stroke, your ability
to benefit from one of these drugs is greater and justifies the possible
side effects of a medication,” said Dr Feinstein said.
A new predictive algorithm may need to be developed to determine the actual risk for MI and stroke in people with HIV, he noted.
The study was conducted using a large, multi-centre clinical cohort
of HIV-positive individuals receiving care at 1 of 5 participating sites
around the country. The researchers analysed data from approximately
20,000 HIV-positive individuals. They compared predicted rates of MIs
based on data from the general population to the actual rates of MIs
observed in this cohort.
The primary driver of the higher risk is the HIV, scientists believe.
“There is chronic inflammation and viral replication even in people
whose blood tests don't show any sign of the virus in the blood,”
explained Dr. Feinstein.
That's because the virus still lurks in the body's tissues, creating
the inflammation that causes plaque build-up that can lead to a MI or a
stroke. This build-up occurs 10 to 15 years earlier in patients with HIV
than in people without HIV.
“It's this inflammatory state that seems to drive this accelerated
aging and these higher risks for heart disease, which are becoming more
common in HIV patients as they live longer,” said Dr. Feinstein.
The current study builds on previous HIV-related heart disease
research by Feinstein, published in November, 2016, which found that
individuals with HIV had more scarring in the heart muscle after MIs,
indicating an impaired ability to heal their hearts. Reasons for this
are unknown but are an area of active study for Feinstein and his
colleagues.
A clinical trial is underway at Northwestern Medicine to evaluate how
well common medications for heart disease prevention and treatment,
such as statin medications, work to prevent heart disease in the
HIV-infected population.

Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 28,983 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.
What this blog is for:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.
