Chest pain may still be angina even when the main heart arteries look clear. Using cardiac stress MRI (a heart scan that measures blood flow with magnetic resonance imaging), testing uncovered small vessel problems in about half of participants in a study of people who had prior coronary angiography that indicated no obstructive coronary artery disease.

Two P2Y12 inhibitors often used interchangeably, ticagrelor and prasugrel (antiplatelet medications prescribed to prevent the formation of blood clots), had different impacts on outcomes in patients with Type 1 or Type 2 diabetes who had undergone stent placement, a procedure done to keep an artery open, and free of clots or a blockage.

Adults in rural villages in China who participated in the Healthy Family Program, a family-based intervention that involved regular blood pressure monitoring, the use of low-sodium salt substitutes and educational sessions on healthy lifestyle habits, achieved an average of 10 mm Hg reduction in systolic blood pressure compared to adults who did not participate in the program.

A grocery support program based on the low-sodium DASH eating plan that included home-delivered groceries and dietary counseling reduced blood pressure levels in Black adults living in areas where grocery stores were inaccessible or scarce, known as food deserts.

A study of 400 adults with high blood pressure found that participants were twice as likely to take their blood pressure medication (measured by electronic pill bottles that recorded when bottles were opened) when they could win a daily cash reward compared to people who were not offered a potential reward.
