Cardiovascular

Blood clots can be dangerous, and blood thinning drugs aren’t always enough to clear them out. Now, researchers at North Carolina State University have demonstrated an ultrasonic “drill” that can break clots apart with the help of tiny nanodroplets.

A new study has affirmed the link between the presence of brown fat and improved cardiac or metabolic health, validating the relatively new hypothesis that the type of adipose tissue commonly referred to as brown fat confers broad health benefits.

Minute differences in the blood pressure between each arm aren’t cause for concern, but there is a point at which variances could represent cardiovascular trouble, and an expansive international study has shone new light on where that point lies.

A new observational study, analyzing data from nearly half a million UK subjects, suggests improving sleep behavior is an important intervention for both clinicians and patients looking to reduce risk of heart failure.

A phase 2 clinical trial of a cholesterol-reducing drug called evinacumab has reported promising results. In patients with extremely high cholesterol, the drug was able to reduce levels by about half, compared to a placebo.

A new study has identified a complex relationship between disturbed sleep patterns, elevated blood pressure, and disruptions to the gut microbiome. The findings could point to novel treatments to mitigate the negative health effects of poor sleep.

A meta-analysis suggests naps lasting more than 60 minutes can be linked to higher rates of all-cause mortality and poor cardiovascular health. Although the finding is only correlational, the researchers suggest keep your siestas to less than one hour.

New research is suggesting a simple saliva test can detect the presence of a protein biomarker known to signal the occurrence of a heart attack in just 10 minutes, potentially accelerating the speed at which patients can be diagnosed and treated.

A new algorithm has been developed to detect coronary artery disease solely from patient facial photos. The algorithm needs more refinement but experts suggest there are ethical considerations to resolve before a system like this can be deployed.

A pair of new studies highlight the potential for long-term heart complications in recovered COVID-19 patients. The research suggests the virus can damage cardiovascular muscles with inflammation detectable months after recovery, even in mild cases.

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

A new study, led by researchers at the Broad Institute of MIT and Harvard, is shedding light on a century-old mystery. The study describes how bacteria in the gut can metabolize cholesterol at levels high enough to improve a person’s cardiac health.
