The Atrial fibrillation Better Care (ABC) pathway has been proposed to streamline patient management in an integrated, holistic manner. Compliance to ABC resulted in lower incidence of cardiovascular events, but its impact on health-related costs has not been evaluated. ⋯ Management of atrial fibrillation patients according to the ABC pathway was associated with significantly lower health-related costs. Application of the ABC pathway may help reduce healthcare costs related to cardiovascular events in this high-risk patient population.

Heart failure with preserved ejection fraction (HFpEF) is increasing in prevalence and has no guideline-recommended therapy, related in part to a lack of mechanism. Traditionally, HFpEF was thought to be secondary to afterload overload due to systemic hypertension; however, accumulating evidence suggests that HFpEF continues to worsen despite adequate control of blood pressure. ⋯ Further, the most prevalent clinical phenotype (eg older women with multiple comorbidities) of patients with HFpEF resembles those with coronary microvascular dysfunction, albeit older. In this review, we provide in-depth insight about this emerging HFpEF paradigm, discuss potential therapeutic implications of this pathophysiology, and summarize some important knowledge gaps.
