Utilizing Invasive Coronary Functional Testing in a Coronary Microvascular and Vasomotor Dysfunction Program: Methods and Considerations.

Background: Coronary microvascular and vasomotor dysfunction (CMVD) is associated with a threefold increased risk of major adverse cardiovascular events (MACE) and is the primary mechanism responsible for angina/ischemia in patients with nonobstructive coronary artery disease (ANOCA/INOCA). Proper assessment for CMVD is vital to provide targeted treatment and improve patient outcomes. Invasive coronary functional testing (ICFT) is the "gold standard," for CMVD assessment and can be used to diagnose all endotypes.

Developing a Women's Heart Center With a Specialization in Coronary Microvascular and Vasomotor Dysfunction: If You Build It, They Will Come.

Background: Women's Heart Centers (WHC) are comprehensive, multidisciplinary care centers designed to close the existing gap in women's cardiovascular care. The WHC at The Christ Hospital Heart and Vascular Institute (TCH-WHC) in Cincinnati, Ohio was established in October of 2020, and is a specialized coronary microvascular and vasomotor dysfunction (CMVD) program.

Methods: The TCH-WHC focuses its efforts across five pillars: patient care, research, education, community outreach and advocacy, and grants and philanthropy.

Central but not peripheral oxytocin administration reduces risk-based decision-making in male rats.

The hormone oxytocin has long been associated with social behaviors, but recent evidence suggests that it may also affect reward processing in non-social contexts. Decisions are an integral component of many social and reward-based behavioral paradigms. Thus, a broad role for oxytocin in decision-making may explain the wide variety of effects that have been previously observed and resolve controversies in the literature about its role.

Extent of food restriction affects probability but not delay-based decision-making.

Rodent studies on decision-making often use food rewards and food-restrict subjects in order to motivate performance. However, food restriction has widespread effects on brain and behavior, which depend on factors including extent of restriction and feeding schedule. These factors are well recognized for their effects on motivation, but may also cause effects on decision-making independent of motivation.

Effects of Nicotine on Alcohol Drinking in Female Mice Selectively Bred for High or Low Alcohol Preference.

Background: Studies show that repeated nicotine use associates with high alcohol consumption in humans and that nicotine exposure sometimes increases alcohol consumption in animal models. However, the relative roles of genetic predisposition to high alcohol consumption, the alcohol drinking patterns, and the timing of nicotine exposure both with respect to alcohol drinking and developmental stage remain unclear. The studies here manipulated all these variables, using mice selectively bred for differences in free-choice (FC) alcohol consumption to elucidate the role of genetics and nicotine exposure in alcohol consumption behaviors.
