This study looked at whether garlic supplements can improve blood vessel function and reduce inflammation in adults with chronic kidney disease who are on hemodialysis. Fifty-eight patients took garlic extract or a placebo for a period of time. Researchers measured markers of blo…

This study tested whether a daily supplement called COMP-4 can improve blood vessel function and reduce signs of aging in 32 healthy adults aged 18-39. Participants took the supplement for 14 days, and researchers used ultrasound to measure blood vessel dilation and blood tests t…

This small study tested whether a gentle electrical pulse to the ear (transcutaneous vagal stimulation) could improve blood vessel function in 11 people with peripheral artery disease (PAD). The approach aims to calm the nervous system and reduce inflammation, potentially helping…

This study examined whether bacteria from gum disease are found in artery plaque and whether they affect mitochondrial DNA (a marker of cell health). Researchers analyzed plaque samples from 51 people who had artery-clearing surgery. The goal was to understand connections, not to…

This study looked at tiny blood vessels in the skin of people with resistant hypertension (high blood pressure that doesn't respond well to multiple drugs). Researchers compared 111 participants to see if changes in these vessels could help predict heart risks. The goal was to fi…

This study measured how e-hookah vaping affects the cells lining blood vessels in 33 young adults aged 21–39. Researchers compared the effects of nicotine-containing and nicotine-free vapor to see if nicotine was responsible for blood vessel damage. The goal was to understand the…

This early-stage study tested whether drinking beetroot juice (rich in natural nitrates) could improve blood vessel stiffness and brain blood flow in 16 adults aged 50-79. Participants were randomly assigned to drink either nitrate-rich or nitrate-free beetroot juice. The goal wa…

This study looked at whether PTSD can damage blood vessels, which may lead to heart disease. Researchers measured how well blood vessels expand in 168 adults who had experienced trauma. The goal was to understand which PTSD symptoms are most harmful to heart health, without offer…

This study looked at 51 people to understand why those with a rare genetic condition called POR deficiency often develop high blood pressure and blood vessel damage. Researchers compared blood pressure patterns and specific blood markers between patients and healthy volunteers. T…

This study looked at medical records of 380 men to see if a score called Modified EASIX, calculated from routine blood tests, can help predict how severe erectile dysfunction (ED) is. Researchers compared the scores of men with and without ED. No treatments or extra tests were gi…
