MAGT1 Deficiency Dysregulates Platelet Cation Homeostasis and Accelerates Arterial Thrombosis and Ischemic Stroke in Mice
CONCLUSIONS: These results suggest that MAGT1 and TRPC6 are functionally linked. Therefore, deficiency or impaired functionality of MAGT1 could be a potential risk factor for arterial thrombosis and stroke.PMID:37381987 | DOI:10.1161/ATVBAHA.122.318115

Calcium in Arteries May Best Predict Risk of Heart Attack, Stroke
THURSDAY, Aug. 31, 2017 -- People with no calcium buildup in their arteries seem to have a significantly lower risk of heart attack and stroke, a new study finds. Calcium collects in the arteries after plaque builds up and hardens over time, the...

Relationship between sleep disordered breathing and coronary artery calcium in ischemic stroke patients
Introduction: Obstructive Sleep Apnea (OSA) is associated with increased risk of stroke and cardiovascular mortality. In ischemic patients, the major cause of death during follow-up is coronary artery disease. Coronary calcium score (CAC) is a score measured from quantification of calcified plaques with chest computed tomography. CAC has been shown to be associated with future risk of myocardial infarction and cardiovascular mortality. Several studies showed the positive correlation between sleep apnea and CAC in normal population, which may be contributed by progressive worsening of atherosclerosis.

Magnesium as a Neuroprotective Agent: A Review of Its Use in the Fetus, Term Infant with Neonatal Encephalopathy, and the Adult Stroke Patient
This article explores the current status of magnesium being used as an adjunct to hypothermia in term neonatal encephalopathy (NE) against a background of its use in other populations. There is some evidence for magnesium sulfate as a neuroprotective agent, however animal studies of NE at term equivalent age have been confounded by concomitant hypothermia induced by magnesium itself. Nevertheless, the combination of magnesium and cooling has been shown to be more effective than either treatment alone in adult rodents. In the preterm baby, magnesium sulfate given antenatally in threatened preterm labor has demonstrated a si...

Researchers Create Heart Attack Prediction Tool
DALLAS, Texas (CBS Local) – Will you have a heart attack within the next ten years? Medical researchers affiliated with Dallas-based UT Southwestern Medical Center have unveiled an online tool designed to “calculate” a person’s risk level for heart attack or stroke. Astro-CHARM specifically combines a person’s heart health factors, including cholesterol, blood pressure, and family history. The site also needs input of a person’s artery calcium level. By specifically calculating the data together, the Astro-CHARM calculator provides a percentage figure, to assess heart attack and/or disease over a ten ye...

Prognostic value of coronary artery disease-reporting and data system (CAD-RADS) score for cardiovascular events in ischemic stroke
The coronary artery disease-reporting and data system (CAD-RADS) was recently developed to standardize CAD classifications and incorporate clinical management. We aimed to investigate the prognostic value and additional risk stratification benefits of the CAD-RADS compared to coronary artery calcium scores (CACS) and CAD extent classifications in ischemic stroke patients without cardiac symptoms.

Mystery of why arteries harden may have been solved, say scientists
Study finds calcium deposits are triggered by molecule produced by damaged cellsThe mysterious mechanism behind the hardening of arteries may have been solved, researchers have revealed, in a study that also suggests the first potential preventive drug for the condition linked to heart attack, dementia and stroke.Arteries harden as calcium becomes deposited in the elastic walls of the vessels, a process that happens as we age and is exacerbated for patients with diabetes or kidney disease. Stiffening can also occur as calcium becomes deposited in fatty plaques in the arteries – a condition called atherosclerosis.Continue reading...

Reversal of Global Ischemia-Induced Cognitive Dysfunction by Delayed Inhibition of TRPM2 Ion Channels
AbstractHippocampal injury and cognitive impairments are common after cardiac arrest and stroke and do not have an effective intervention despite much effort. Therefore, we developed a new approach aimed at reversing synaptic dysfunction by targeting TRPM2 channels. Cardiac arrest/cardiopulmonary resuscitation (CA/CPR) in mice was used to investigate cognitive deficits and the role of the calcium-permeable ion channel transient receptor potential-M2 (TRPM2) in ischemia-induced synaptic dysfunction. Our data indicates that absence (TRPM2−/−) or acute inhibition of TRPM2 channels with tatM2NX reduced hippocampal cell dea...

Roles Played by the Na+/Ca2+ Exchanger and Hypothermia in the Prevention of Ischemia-Induced Carrier-Mediated Efflux of Catecholamines into the Extracellular Space: Implications for Stroke Therapy.
Abstract The release of [3H]dopamine ([3H]DA) and [3H]noradrenaline ([3H]NA) in acutely perfused rat striatal and cortical slice preparations was measured at 37 °C and 17 °C under ischemic conditions. The ischemia was simulated by the removal of oxygen and glucose from the Krebs solution. At 37 °C, resting release rates in response to ischemia were increased; in contrast, at 17 °C, resting release rates were significantly reduced, or resting release was completely prevented. The removal of extracellular Ca2+ further increased the release rates of [3H]DA and [3H]NA induced by ischemic conditions. This findi...

Electroacupuncture ameliorates learning and memory deficits via hippocampal 5-HT1A receptors and the PKA signaling pathway in rats with ischemic stroke
This study aimed to investigate whether PKA signaling mediated by 5-HT1A receptors was involved in the electroacupuncture (EA)-mediated learning and memory in a rat model of middle cerebral artery occlusion-induced cognitive deficit (MICD). Compared to no treatment or non-acupoint EA treatment, EA at DU20 and DU24 acupoints improved the neurological deficit of scores, shortened escape latency and increased the frequency of crossing the platform in the Morris water maze test. T2-weighted imaging demonstrated that the MICD rat brain lesions were mainly located in the cortex and hippocampus, and injured volumes were reduced a...
