Deans' stroke musings: 4C.08: AORTIC STIFFNESS IS AN INDEPENDENT BIOMARKER OF SUBCLINICAL BRAIN DAMAGE IN ACUTE ISCHEMIC STROKE

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.

4C.08: AORTIC STIFFNESS IS AN INDEPENDENT BIOMARKER OF SUBCLINICAL BRAIN DAMAGE IN ACUTE ISCHEMIC STROKE

I have absolutely no clue what they are trying to say, it's not written in understandable English. These people would not get another research grant from any stroke organization I controlled until they learn to write.

Abstract

OBJECTIVE:

Ischemic stroke may be the first manifestation of cerebrovascular disease. However, subclinical organ complications of underlying arterial stiffness and hypertension may coexist and stratify outcome. The study aimed to examine measures of arterial stiffness and blood pressure (BP) on subclinical brain damage in acute ischemic stroke patients.

DESIGN AND METHOD:

In a prospective study, we enrolled 132 (68,6% males) patients with acute ischemic stroke, AIS (age 62.2 ± 12.2 years, admission National Institutes of Health Stroke Scale score 7.1 ± 6.5, mean ± SD). Carotid-femoral pulse wave velocity (CF-PWV), central augmentation index (cAIx), as well as central and peripheral BPs were measured (SphygmoCor, Omron, respectively) one week after stroke onset. The presence of brain subclinical lesions was graded on admission computed tomography scans using van Swieten criteria with any relevant cerebral small vessel disease considered as brain microvascular damage.

RESULTS:

In univariate analysis, high carotid-femoral PWV (p = 0.00005), and high cAIx (p = 0.02) were significantly associated with brain microvascular damage. Age, presence of hypertension, diabetes mellitus, previous ischemic stroke, but not BP values, also predicted brain outcome. In multivariate analysis, the predictive value of carotid-femoral PWV remained significant (OR, 1.30; 95% CI, 1.04-1.62; p = 0.02). By contrast, cAIx had no significant predictive value after adjustment.

CONCLUSIONS:

Increased aortic stiffness is associated with brain microvascular disease in patients with acute ischemic stroke, beyond and above classical risk factors. PWV provides a useful new tool for identification of subclinical brain damage in AIS.
