New blood test could save lives of heart attack victims (Neuropeptide Y (NPY))

Researchers have developed a blood test that measures stress hormone levels after heart attacks. The test could ensure patients receive timely life-saving treatment.

Cardiovascular disease is the main cause of death. One common way is through heart attacks.

New research shows that routine testing for the stress hormone Neuropeptide Y (NPY) in the hours after a heart attack has the potential to save thousands of lives.

Professor Neil Herring said, "Our previous research has shown that NPY is raised during a heart attack and local levels within the heart correlate with how well it recovers. What this new study adds is that high NPY levels, even when measured through a standard blood test from a vein, predict which patients go on to develop heart failure or die."

NPY, once released into the heart, causes its smallest blood vessels to narrow. Researchers found that two days after a heart attack, the smallest blood vessels in the heart remained narrowed in patients with the highest NPY levels. MRI scans carried out six months later found that such patients had more scarring in their hearts, which were thus unable to pump blood efficiently.

NPY levels were measured in standard blood samples taken from the veins of patients when they underwent their PCI treatment. Researchers found that those patients with the highest NPY levels sustained more heart and lung damage, and their hearts were significantly more likely fail irrespective of other risk factors over the subsequent six years. The team concluded that routine tests in the hours after a heart attack could ensure patients at greatest risk were spotted sooner, and prioritized for treatment.

Professor Herring said, "This study identifies a 'cut off' value for the blood test which helps identify those patients that do badly after their large heart attack.

TOPICS: Health/Medicine
KEYWORDS:
This test is cheap and already available at places like Quest Diagnostics.

The level cutoffs for safe versus unsafe levels is in the paper’s abstract:

“Kaplan‐Meier survival analysis demonstrated that high PV NPY levels (>21.4 pg/mL by binary recursive partitioning) were associated with increased incidence of heart failure and mortality (hazard ratio, 3.49 [95% CI, 1.65–7.4]; P<0.001). This relationship was maintained after adjustment for age, cardiovascular risk factors, and previous myocardial infarction.”

So one gets a test with a positive value.

What’s the treatment?

They keep you in the ICU for an extra day or two with all the monitoring on you.

“What’s the treatment?”

To be developed.

From the article...

“This provides extremely useful information for doctors and we hope that developing drugs that target the receptors NPY acts on may really be game changing for this cohort of patients and the blood test could help spot those patients who may need it right from the start.””

Not only racist, but they are non-woke because they use “BINARY recursive partitioning” to measure the PV NPY levels. To be fully inclusive, the tests should be non-binary.

So if high PV NPY values show up what does the Doc do differently?

Asking for a friend. ;-)

Link Filed under "Health" - mostly yours. Thanks - not just for me, really more for friends and family.

What do you have for post-vaxx people to minimize any more damages and maybe clean out the spike protein?
