  1. PURE Objective • Evaluate the use of cardiovascular drugs for secondary prevention across countries with differing levels of economic development Study Design and Methods • Prospective, multinational, epidemiological survey • 153,996 adults (most aged 35 to 70 years) from 628 urban and rural communities in 17 countries • A subset of 5650 patients reported a prior CHD event and 2292 reported a prior stroke • Participating countries were classified as high, upper-middle, lower-middle, and low income, based on World Bank criteria at the beginning of the study • Medical history and use of key secondary preventive medications were assessed through telephone interviews, home visits, and clinic visits

  2. PURE Key Findings • Across all countries, a minority of patients with a history of CHD or stroke reported taking key secondary preventive drugs • Between-country variations in medication use were twice as large as patient-level variability due to age, sex, education, smoking, obesity, hypertension, and diabetes • Medication use was highest in high-income countries and decreased with country income. • Gaps between low-income and high-income countries were approximately 7-fold for aspirin and 20-fold for statins. • Although 88.8% of patients in high-income countries took at least 1 drug for secondary prevention, far fewer patients received any medication in upper-middle, lower-middle, and low-income countries • Patients in urban areas were more likely than those in rural communities to take antiplatelet drugs, β-blockers, ACE inhibitors or ARBs, and statins, regardless of the economic status of the country

  3. PURE Key Findings (continued) • Patients with CVD and hypertension were more likely than those with CVD alone to receive drugs that also lowered blood pressure • Younger patients, women, smokers, and those who were less educated, nonobese, or nondiabetic were less likely to use drugs for secondary prevention Conclusions • A large gap exists in secondary prevention worldwide, with extremely low rates of use of effective therapies in middle- and low-income countries • Efforts to increase the use of effective and inexpensive drugs for prevention of CVD are urgently needed and would substantially reduce disease burden within a few years • These data support the concept of a “polypill,” which has the potential to deliver multiple proven therapies in a single pill in an attempt to close the large treatment gap that was observed in this analysis
