Millions of lives—and billions in healthcare costs—are at stake due to one critical but often ignored issue: failure to follow treatment plans. The World Heart Federation (WHF) warns that non-adherence to medication, lifestyle recommendations, and overall healthcare plans is fuelling preventable hospitalisations, worsening health outcomes, and straining healthcare budgets worldwide. 

To address this crisis, WHF has partnered with leading institutions to mark March 27 as World Adherence Day—a global call to action to ensure patients stay on track with life-saving medicines and healthier lifestyles.
