The study analyzed data from over half a million patients and highlights persistent racial disparities in medical outcomes.
This study investigated the effect of taurine on atherosclerotic plaques in mice. Taurine treatment significantly decreased plaque areas and lowered the ratio of anti-α-SMA to anti-CD68 staining, suggesting potential benefits for cardiovascular health.
A study published in JACC found that metal exposure is associated with progression of plaque buildup in the arteries, comparable to traditional risk factors like smoking and diabetes. The findings support considering metal exposure as a significant risk factor for atherosclerosis and cardiovascular disease.
Researchers discovered that consuming over 22% of daily calories from protein can lead to increased activation of immune cells contributing to atherosclerotic plaque formation. Leucine, an amino acid found in animal-derived foods, plays a disproportionate role in driving pathological pathways linked to atherosclerosis.
A study revealed that natto consumption significantly reduced atherosclerotic lesions in mouse models, altering intestinal microflora and regulating cytokine production. High vitamin K2 natto showed the most significant effect, decreasing pro-inflammatory cytokines while increasing anti-inflammatory IL-10 production.
The Canadian Cardiovascular Society has updated its guidelines to no longer recommend routine daily aspirin use for primary prevention of heart attacks or death. However, daily aspirin may be considered for people with high risk factors for heart attack, such as diabetes, high cholesterol, and smoking. The new guidelines emphasize the ...
Researchers found SARS-CoV-2 directly infects coronary arteries, causing fatty plaque to become inflamed. The virus replicates in macrophages, leading to increased inflammation and potentially worsening cardiovascular complications.
The Texas Heart Institute has been awarded $1.14 million by the NIH to develop a novel, first-in-class drug for treating atherosclerotic cardiovascular disease. The goal of this research is to target lingering inflammation in patients with cardiovascular disease.
Researchers at NUS have developed a new treatment method that reduces the size and increases the stability of atherosclerotic plaques in arterial walls. The treatment involves injecting omega-3 fatty acids into the bloodstream via nanomedicine, which helps to reduce inflammation and prevent plaque rupture.
Researchers at Lund University have mapped the location where atherosclerotic plaques rupture, identifying an enzyme marker that could predict patients at risk of myocardial infarction or stroke. The study's findings may lead to preventive treatments and new therapies.
A study of 1,300 participants found that increased physical activity 6 months after stroke was associated with better functional outcomes. Interventions targeting individuals with decreasing physical activity in the subacute phase may play a role in improved functional recovery.
A cohort study of over 9,000 persons found that asymptomatic middle-aged individuals with subclinical coronary atherosclerosis are at an 8-fold increased risk for myocardial infarction. The study highlights the importance of identifying and addressing obstructive coronary artery disease in patients without known cardiovascular disease.
Researchers from Osaka University found that tricaprin supplementation leads to remarkable regression of coronary artery plaque and resolution of symptoms in patients with triglyceride deposit cardiomyovasculopathy. The study's findings provide a novel treatment concept for coronary atherosclerosis.
Researchers at Osaka University have developed a mouse model that shows Favine protein can protect against atherosclerosis and thrombosis. The study also found that reduced levels of Favine are associated with calcification and thrombus formation, revealing a new potential therapeutic target for treating atherosclerosis.
A study at Tulane University found that recently formed stroke plaques contain messenger RNA that causes inflammation and degrades a protective cap, leading to rupture. This discovery could lead to new tools to stop strokes from happening and develop new drugs or diagnostics to prevent heart attacks and strokes.
A new Mount Sinai study reveals that young Black adults are twice as likely to have atherosclerosis as their Hispanic counterparts. Researchers used comprehensive questionnaires and 3D vascular ultrasounds to determine cardiovascular risk scores, finding significant discrepancies between the groups.
Researchers developed a method combining low-power lasers with ultrasound to safely and efficiently remove arterial plaque. The technique reduces the risk of complications and improves the efficiency of plaque removal compared to traditional methods.
Scientists use advanced measurement methods to study carotid artery stenosis, discovering significant gaps between their findings and clinical methods. They propose improvements for surgical treatment technology and future medical devices.
Researchers discovered a connection between atherosclerotic plaques and the central nervous system, involving immune cells, nerves, and cardiovascular tissues. This 'ABC' circuit can be modulated or disconnected, potentially leading to innovative therapies for treating atherosclerosis.
A new 3D matrix ultrasound method has been developed to assess cardiovascular risk in healthy individuals, offering a reliable and accurate alternative to traditional methods. The technique shows promise for personalized prevention and treatment strategies by detecting and quantifying an individual's accumulated cardiovascular damage.
Researchers have made a significant breakthrough in predicting heart attacks and strokes by developing a non-invasive method using super-resolution ultrasound imaging. The technology aims to detect high-risk atherosclerotic plaques that are prone to rupture, allowing doctors to prescribe life-saving interventions.
