Medicare's Bundled Payments for Care Improvement (BPCI) is a voluntary pilot program evaluating bundled payments for several common cardiovascular conditions. Evaluating the external validity of this program is important for understanding the effects of bundled payments on cardiovascular care. ⋯ Hospitals participating in BPCI model 2 cardiac bundles differed in significant ways from nonparticipating hospitals. The BPCI outcomes may therefore have limited external validity, particularly among small and safety net hospitals with limited clinical cardiac services.

Health insurance is effective in preventing financial hardship from unexpected major health care events. However, it is also essential to assess whether vulnerable patients, particularly those from low-income families, are adequately protected from longitudinal health care costs for common chronic conditions such as atherosclerotic cardiovascular disease (ASCVD). ⋯ One in 4 low-income families with a member with ASCVD, including those with insurance coverage, experience a high financial burden, and 1 in 10 experience a catastrophic financial burden due to cumulative out-of-pocket health care expenses. To alleviate economic disparities, policy interventions must extend focus to improving not only access, but also quality of coverage, particularly for low-income families.

Genetic and lifestyle factors both contribute to the risk of developing cardiovascular disease, but whether poor health behaviors are associated with similar increases in risk among individuals with low, intermediate, or high genetic risk is unknown. ⋯ In this large contemporary population, genetic composition and combined health behaviors and factors had a log-additive effect on the risk of developing cardiovascular disease. The relative effects of poor lifestyle were comparable between genetic risk groups. Behavioral lifestyle changes should be encouraged for all through comprehensive, multifactorial approaches, although high-risk individuals may be selected based on the genetic risk.

Fibromuscular dysplasia (FMD) is a nonatherosclerotic arterial disease that predominately affects women and is most commonly diagnosed in middle age. The natural history of FMD among patients diagnosed at an older age is not well understood. ⋯ In the US Registry for FMD, patients 65 years or older at the time of diagnosis of multifocal FMD were more likely to be asymptomatic, had lower prevalence of major vascular events, and had undergone fewer therapeutic vascular procedures than younger patients. Patients with multifocal FMD diagnosed at an older age may have a more benign phenotype and fewer symptoms.
