Objective Diagnosis of Migraine Without Aura With Migraine Vascular Index: A Novel Formula to Assess Vasomotor Reactivity [PDF]

open access: yesUltrasound in Medicine and Biology, 2020
This pilot study was aimed at developing an objective method to diagnose migraine by measuring the difference in vasomotor reactivity between migraineurs and non-migraineurs. Thirty patients diagnosed with migraine without aura and 30 healthy patients were recruited. Vasomotor reactivity of all patients was then assessed by measuring the breath holding

Vascular Reactivity Index as an Effective Predictor of Mortality in Children With Refractory Septic Shock

Journal of Intensive Care Medicine, 2020
Background: Vasoplegia is vascular hyporesponsiveness to vasopressors and is an important phenomenon in children with refractory septic shock. This study aimed to develop an objective formula correlated with vasoplegia and evaluate the predictive power for mortality in children with refractory septic shock.

Vascular Reactivity Index as an Effective Predictor of Mortality in Patients With Septic Shock: A Retrospective Study

Journal of Intensive Care Medicine
Background Sepsis is a serious complication that occurs after trauma, burns, and infections, and it is an important cause of death in intensive care unit (ICU) patients. Despite many new measures being proposed for sepsis treatment, its mortality rate remains high; sepsis has become a serious threat to human ...

Quantitative Assessment of Pulmonary Vascular Resistance and Reactivity in Children with Pulmonary Hypertension Due to Congenital Heart Disease Using a Noninvasive Method: New Doppler-Derived Indexes

Pediatric Cardiology, 2008
We assessed the usefulness of transthoracic Doppler-derived indexes obtained in the proximal pulmonary artery (PA) branch for estimating pulmonary vascular resistance (PVR) in 45 children with congenital heart disease (CHD) and 23 normal control subjects.

[Prognostic evaluation of vascular reactivity to vasoactive drugs and the clinical index of disease severity in patients with myocardial infarction].

Kardiologiia, 1992
The parameters of vascular responsiveness to vasopressors and vasodilators and the clinical severity index were determined in 45 patients with various acute myocardial infarction (AMI) extents in the hospital period. In a group of patients with small AMI foci, the responsiveness to vasopressors normalized on day 14 with normal parameters to ...
