— Recent developments of interest in cardiovascular medicine

A small safety study of stem cells surgically transplanted into the brain of patients unable to ambulate 5 years after a stroke turned up some tantalizing efficacy signals, with some patients reportedly able to stand or walk again.

The CDC reports that just shy of three-quarters of adults with hypertension say they are taking antihypertensives, based on the National Health and Nutrition Examination Survey for 2011 to 2014.

The World Heart Federation and other organizations signed the Mexico Declaration for Circulatory Health calling on governments to enact laws to promote healthy lifestyles, tax unhealthy products, and make effective cardiovascular disease treatments more accessible.

Whereas lower is typically better for LDL, that wasn't the case in the type 2 diabetes SMART cohort. Rather, those with LDL under 77 mg/dL and a high HDL level were actually at higher risk of cardiovascular events and all-cause mortality than those with higher LDL. Why is unclear, the researchers cautioned.

The kind of meta-data available to the National Security Agency could reveal who has atrial fibrillation, according to a team of researchers who made a correct guess in one case based on the record of a call to a cardiac monitoring device hotline.

The FDA warned of infections from the Sorin/LivaNova 3T heater-cooler tank due to aerosolized M. chimaera, particularly for patients getting a heart valve or other cardiac prosthesis, although the production line source appears to have been cleaned up since 2014.

A small study turned up no myocardial infarction or stroke among patients on triptans and dihydroergotamine to treat basilar and hemiplegic migraines, despite the boxed warning for both types of drugs.

A pivotal trial was okayed by the FDA for the Revivent TC TransCatheter Ventricular Enhancement System, which involves titanium anchors placed in a hybrid closed-chest transcatheter procedure that are then pulled toward each other to reshape the left ventricle in ischemic cardiomyopathy patients.
