Eating unsalted peanuts improves the brain's vascular health

MRIs show how peanut consumption improves the brain's vascular function

Consistently incorporating unsalted peanuts into a person’s diet enhances cerebral blood flow to multiple brain regions. 

Carlos Collet, MD, PhD, director, cardiovascular imaging, physiology and translational therapeutics, Cardiovascular Research Foundation, explains how noninvasive coronary CT angiography (CCTA) assessments will play a major role to eliminate invasive diagnostic angiography and to pre-plan percutaneous coronary intervention (PCI) procedures.

CCTA will play an essential role in the cath labs of the future

Noninvasive coronary CT angiography is growing more and more important as time goes on, helping cardiologists make critical treatment decisions. Carlos Collet, MD, PhD, discussed the technique's potential to be a real game-changer for patient care in a new interview.

Is long-term melatonin use safe? New study highlights heart risks

Taking melatonin for a year could increase a person's risk of developing heart failure by 90%. While more research is still needed to confirm these findings, the data suggest patients should think twice about relying on melatonin to sleep.

Large-scale policy changes fail to boost heart failure outcomes—what else is needed?

A system-wide initiative in Sweden helped hospitals reduce readmission rates and shorten lengths of stay. When it came to heart failure patients specifically, however, the changes barely made an impact.

To eat or not to eat: Is fasting still necessary before heart procedures?

As one may expect, patient satisfaction was considerably higher for individuals who did not have to fast for a minimum of six hours prior to treatment. There were no other significant differences.

Mechanical thrombectomy beats anticoagulation alone in STORM-PE

Highly anticipated trial data comparing mechanical thrombectomy to anticoagulation alone for intermediate- and high-risk pulmonary embolism showed that the more aggressive strategy improved outcomes.

Mitral annular calcification linked to higher heart failure risks

In fact, researchers wrote, MAC appears to influence a patient's odds of developing HFpEF even more than their BMI.

Pulmonary embolism thrombectomy use increases by more than 700%

Medicare claims submitted between 2017 and 2022 showed a 712% increase in thrombectomy for pulmonary embolism (PE) and a 137% increase in thrombectomy for deep vein thrombosis (DVT).
