Research finds a strong association between retinal age and real age, with large gaps associated with increased mortality risk. The 'retinal age gap' could be used as a screening tool to predict mortality risk, particularly for non-cardiovascular causes.
A new imaging technique can detect early signs of blood trauma in red blood cells, which could aid in the development of markers to prevent damage. The technique, developed by researchers at Shibaura Institute of Technology and Griffith University, uses high-speed cameras to visualize changes in RBC shape under stress.
A new meta-analysis published in the European Journal of Preventive Cardiology suggests that Sodium-glucose co-transporter-2 (SGLT2) inhibitors can improve outcomes for heart failure patients with preserved ejection fraction. The medication has been shown to reduce the risk of death from heart-related causes and hospitalization by 22%.
Researchers at GIST create an optical technique called optical speckle image velocimetry that can image dynamic changes in cerebral blood flow, allowing for the diagnosis of brain health. The technique provides high-time resolution and measures both speed and direction of blood flow.
Researchers from Aarhus University have developed a revolutionary technique to identify pathogenic particles in the blood, which determine the development of autoimmune diseases like Systemic Lupus Erythematosus. The technique allows for early diagnosis and potentially life-threatening consequences such as blood clots and organ damage.
Exercise with face masks or respirators can cause detrimental effects on the cardiovascular system, including cardiac arrhythmias and spontaneous pneumothorax. Masks designed for runners with minimal oxygen deficiency side effects are recommended for high-risk individuals.
A patented technology monitors stroke survivors' health parameters from the brain and cardiovascular system. Post-stroke rehabilitation starts instantly after medical stabilization, with a high risk of second strokes within 4 years.
A new metabolism regulation system was found in brown adipose tissue using the kallikrein-kinin hormonal system, which can help prevent damaging effects of excessive activation. This discovery could lead to strategies for moderating thermogenic activity in pathological situations like cancer.
The study examines coronavirus disease 2019's (COVID-19) effects on the cardiovascular system, revealing potential long-term consequences. Researchers highlight the need for further investigation into the relationship between coronaviruses and cardiovascular health.
The American grasshopper's circulatory system responds dramatically to changes in body position due to gravity, affecting blood and air distribution. Physiological compensation mechanisms similar to vertebrates suggest an ancient, widespread response to gravitational forces.
A clinical trial called GutHeart Trial examines the relationship between gut bacteria and heart failure, testing antibiotic, probiotic yeast, or no treatment on patients with heart failure. The study aims to develop new treatment strategies and better understand how gut leakage affects inflammatory processes and heart failure.
Researchers discuss traditional Chinese medicine approaches for cardiovascular disease, including acupuncture, moxibustion, Qigong, and Tai Chi. They highlight the need for modern TCM research into active ingredients and their applications.
Researchers present a case study on ischemic secondary mitral regurgitation, highlighting the importance of multidisciplinary teams in managing this complex condition. Newer technologies provide new hope for patients, improving outcomes and treatment options.
A new family of earthworms, Kazimierzidae, has been established for a South African genus with an exclusive circulatory system. The species are restricted to small areas along the western and south-western Atlantic coast of South Africa.
Katerina Akassoglou, a Gladstone Senior Investigator, has been awarded a $5.8M NINDS grant to advance her research on the role of brain's vascular and immune systems in neurological diseases. The grant will enable her lab to pursue innovative solutions for devastating conditions like multiple sclerosis.
Research shows that cane toads can adapt well to rising temperatures, with their oxygen transport system becoming more efficient as heat rises. The findings contradict previous studies suggesting a decrease in efficiency at high temperatures, and may have implications for other anurans.
A new study from Cornell University finds that adolescents exposed to chronic risk factors experience stress-induced physiological strain, but with responsive mothers, this toll is significantly reduced. The study also reveals that cardiovascular systems of youths are compromised regardless of their mothers' responsiveness.
New research highlights the impact of concurrent health problems on older adults, with 24% of Medicare beneficiaries aged 65+ and 31.4% of those 85+ having multiple comorbidities. The study aims to improve understanding of comorbidity and develop a comprehensive nosology for classification.
Women undergoing drug-induced labor have nearly a two-fold increased risk of amniotic-fluid embolism, a rare but serious delivery complication. The study found that labour induction increases the risk of this condition, with fatal cases being 3.5 times more frequent.
Researchers found that misdiagnosed electrocardiographic artifact, caused by body movement or poor contact, led to unnecessary procedures like pacemaker implants and heart catheterization. The study highlights the need for improved training in recognizing artifact and increased awareness among physicians.
Researchers at the Brain Attack Team (BAT) are developing Tele-BAT, a system that enables remote evaluation of stroke patients via video, cellular telephone, and computer technology. This allows for faster diagnosis and treatment, as it can provide valuable information to emergency rooms before patients arrive.
The University of Maryland Medical Center has implemented a telemedicine system to assess stroke patients in real-time during ambulance rides, reducing evaluation time by up to 20 minutes. This technology enables the transmission of blood analysis, vital signs, and neurological symptoms to doctors' computer screens.
A new system, Home Health Monitor, developed by Dr. Boaz Avitall, closely monitors congestive heart failure patients in their homes, resulting in fewer readmissions and lower healthcare costs. The system detects complications early and makes patients feel secure, reducing hospitalization rates.
