METHODS: Between 2020-2023, adults hospitalized in the preceding 6-24 months with incident or recurrent CHD were sampled in 14 countries from all 6 World Health Organization regions and invited for a standardized interview and examination. Direct age and sex standardization was used for country-level prevalence estimation.
RESULTS: Overall, 4548 (21.1% female) CHD patients were interviewed a median of 1.05 (interquartile range 0.76-1.45) years after index hospitalization. Among all participants, 24% were obese (40% centrally). Only 38.5% achieved a blood pressure (BP) <130/80 mmHg and 19.2% a low-density lipoprotein cholesterol (LDL-C) of <1.4 mmol/l. Of those smoking at hospitalization, 48% persisted at interview. Of those with known diabetes, 56% achieved glycated hemoglobin (HbA1c) of <7.0%. A further 9.8% had undetected diabetes and 26.9% impaired glucose tolerance. Females were less likely to achieve targets: BP (females 37.4% males 38.6%), LDL-C (females 13.7% males 18.6%) and HbA1c in diabetes (females 47.7% males 57.5%). Overall, just 9.0% (inter-country range 3.8%-20.0%) reported attending cardiac rehabilitation and 1.0% (inter-country range 0.0%-2.4%) achieved the study definition of optimal guideline adherence.
CONCLUSIONS: INTERASPIRE demonstrates inadequate and heterogeneous international implementation of guideline standards for secondary prevention in the first year after CHD hospitalization, with geographic and sex disparity. Investment aimed at reducing between-country and between-individual variability in secondary prevention will promote equity in global efforts to reduce the burden of CHD.
METHODS AND RESULTS: Of the 27 395 patients enrolled in COMPASS, 12 964 (mean age at baseline 67.2 years) from 455 sites in 32 countries were enrolled in LTOLE and treated with the combination of rivaroxaban and aspirin for a median of 374 additional days (range 1-1191 days). During LTOLE, the incident events per 100 patient years were as follows: for the primary outcome [cardiovascular death, stroke, or myocardial infarction (MI)] 2.35 [95% confidence interval (CI) 2.11-2.61], mortality 1.87 (1.65-2.10), stroke 0.62 (0.50-0.76), and MI 1.02 (0.86-1.19), with CIs that overlapped those seen during the randomized treatment phase with the combination of rivaroxaban and aspirin. The incidence rates for major and minor bleeding were 1.01 (0.86-1.19) and 2.49 (2.24-2.75), compared with 1.67 (1.48-1.87) and 5.11 (95% CI 4.77-5.47), respectively, during the randomized treatment phase with the combination.
CONCLUSION: In patients with chronic CAD and/or PAD, extended combination treatment for a median of 1 year and a maximum of 3 years was associated with incidence rates for efficacy and bleeding that were similar to or lower than those seen during the randomized treatment phase, without any new safety signals.
