Daily Sugary Drinks Leads to Increased CVD Risk in Women

A new study in the Journal of the American Heart Association suggests that a daily intake of even one serving of sugary beverages is linked with in increased risk for cardiovascular disease in women. The study consisted of more than 106,000 participants. “Although the study is observational and does not prove cause and effect, we hypothesize that sugar may increase the risk of CVD in several ways,” lead author Cheryl Anderson, PhD, MPH., MS, professor and interim chair of Family and Public Health, University of California San Diego, and chair of the American Heart Association’s Nutrition Committee, said in a news release. “It raises glucose levels and insulin concentrations in the blood, which may increase appetite and lead to obesity, a major risk factor for cardiovascular disease.”

Analysis: Stroke Evaluations Drop Nearly 40% Due to COVID-19

A short research letter in the New England Journal of Medicine highlighted findings from an analysis that showed a 39% decrease in stroke evaluations due to the COVID-19 pandemic. “Across the board, everybody is affected by this decrease,” said Akash Kansagra, MD, assistant professor of radiology and neurology at Washington University’s Mallinckrodt Institute of Radiology, and the lead author of the analysis, said in a news release. “It is not limited to just hospitals in urban settings or rural communities, small hospitals or large hospitals. It is not just the old or the young or the people with minor strokes who aren’t showing up. Even patients with really severe strokes are seeking care at reduced rates. This is a widespread and very scary phenomenon.”

COVID-Friendly Receptor More Prevalent in Blood of Men than Women

Authors for this study measured ACE2 concentrations (a binding enzyme used by COVID-19) in 1,485 men and 537 women with heart failure (the index cohort), and results were then validated in 1,123 men and 575 women (the validation cohort). Average age in the cohorts was 69 years for men and 75 years for women. According to the study, the strongest predictor of elevated ACE2 concentrations was male sex (P<0.001). The use of ACE inhibitors, angiotensin receptor blockers (ARBs), or mineralocorticoid receptor antagonists (MRAs) were not independent predictors of plasma ACE2.

A New Selectively-Pulsed Ablation Catheter for AFib: First-in-Human Study

This first-in-human study included 76 patients with atrial fibrillation. “A novel lattice-tip catheter could safely and rapidly ablate AF using either a combined RF/PF approach (capitalizing on the safety of pulse field ablation and the years of experience with radiofrequency energy) or an entirely pulse field approach,” the researchers concluded.
