- BACKGROUND AND PURPOSE: The HOPE-3 trial (Heart Outcomes Prevention Evaluation-3) found that antihypertensive therapy combined with a statin reduced first stroke among people at intermediate cardiovascular risk. We report secondary analyses of stroke outcomes by stroke subtype, predictors, treatment effects in key subgroups. METHODS: Using a 2-by-2 factorial design, 12705 participants from 21 countries with vascular risk factors but without overt cardiovascular disease were randomized to candesartan 16 mg plus hydrochlorothiazide 12.5 mg daily or placebo and to rosuvastatin 10 mg daily or placebo. The effect of the interventions on stroke subtypes was assessed. RESULTS: Participants were 66 years old and 46% were women. Baseline blood pressure (138/82 mm Hg) was reduced by 6.0/3.0 mm Hg and LDL-C (low-density lipoprotein cholesterol; 3.3 mmol/L) was reduced by 0.90 mmol/L on active treatment. During 5.6 years of follow-up, 169 strokes occurred (117 ischemic, 29 hemorrhagic, 23 undetermined). Blood pressure lowering did not significantly reduce stroke (hazard ratio [H R], 0.80 [95% CI, 0.59-1.08]), ischemic stroke (H R, 0.80 [95% CI, 0.55-1.15]), hemorrhagic stroke (HR, 0.71 [95% CI, 0.34-1.48]), or strokes of undetermined origin (HR, 0.92 [95% CI, 0.41-2.08]). Rosuvastatin significantly reduced strokes (H R, 0.70 [95% CI, 0.52-0.95]), with reductions mainly in ischemic stroke (H R, 0.53 [95% CI, 0.37-0.78]) but did not significantly affect hemorrhagic (H R, 1.22 [95% CI, 0.59-2.54]) or strokes of undetermined origin (H R, 1.29 [95% CI, 0.57-2.95]). The combination of both interventions compared with double placebo substantially and significantly reduced strokes (HR, 0.56 [95% CI, 0.36-0.87]) and ischemic strokes (HR, 0.41 [95% CI, 0.23-0.72]). CONCLUSIONS: Among people at intermediate cardiovascular risk but without overt cardiovascular disease, rosuvastatin 10 mg daily significantly reduced first stroke. Blood pressure lowering combined with rosuvastatin reduced ischemic stroke by 59%. Both therapies are safe and generally well tolerated.

- Aims: Rosuvastatin (10 mg per day) compared with placebo reduced major adverse cardiovascular (CV) events by 24% in 12 705 participants at intermediate CV risk after 5.6 years. There was no benefit of blood pressure (BP) lowering treatment in the overall group, but a reduction in events in the third of participants with elevated systolic BP. After cessation of all the trial medications, we examined whether the benefits observed during the active treatment phase were sustained, enhanced, or attenuated.Methods and results: After the randomized treatment period (5.6 years), participants were invited to participate in 3.1 further years of observation (total 8.7 years). The first co-primary outcome for the entire length of follow-up was the composite of myocardial infarction, stroke, or CV death [major adverse cardiovascular event (MACE)-1], and the second was MACE-1 plus resuscitated cardiac arrest, heart failure, or coronary revascularization (MACE-2). In total, 9326 (78%) of 11 994 surviving Heart Outcomes Prevention Evaluation (HOPE)-3 subjects consented to participate in extended follow-up. During 3.1 years of post-trial observation (total follow-up of 8.7 years), participants originally randomized to rosuvastatin compared with placebo had a 20% additional reduction in MACE-1 [95% confidence interval (CI), 0.64-0.99] and a 17% additional reduction in MACE-2 (95% CI 0.68-1.01). Therefore, over the 8.7 years of follow-up, there was a 21% reduction in MACE-1 (95% CI 0.69-0.90, P = 0.005) and 21% reduction in MACE-2 (95% CI 0.69-0.89, P = 0.002). There was no benefit of BP lowering in the overall study either during the active or post-trial observation period, however, a 24% reduction in MACE-1 was observed over 8.Conclusion: The CV benefits of rosuvastatin, and BP lowering in those with elevated systolic BP, compared with placebo continue to accrue for at least 3 years after cessation of randomized treatment in individuals without cardiovascular disease indicating a legacy effect.

- To compare the prevalence of electrocardiogram (ECG)-documented atrial fibrillation (or flutter) (AF) across eight regions of the world, and to examine anti-thrombotic use and clinical outcomes.Baseline ECGs were collected in 153,152 middle-aged participants (ages 35 to 70 years) to document AF in two community-based studies, spanning 20 countries. Medication use and clinical outcome data (mean follow up of 7.4 years) were available in one cohort. Cross sectional analyses were performed to document the prevalence of AF and medication use, and associations between AF and clinical events were examined prospectively. Mean age of participants was 52.1 years, and 57.7% were female. Age and sex-standardized prevalence of AF varied 12-fold between regions; with the highest in North America, Europe, China and Southeast Asia (270-360 cases per 100,000 persons); and lowest in the Middle East, Africa, and South Asia (30-60 cases per 100,000 persons)(p<0.001). Compared with low-income countries (LICs), AF prevalence was 7-fold higher in middle-income countries (MICs) and 11-fold higher in high-income countries (HICs)(p<0.001). Differences in AF prevalence remained significant after adjusting for traditional AF risk factors. In LICs/MICs, 24% of participants with AF and a CHADS2 score ≥1 received anti-thrombotic therapy, compared with 85% in HICs. AF was associated with an increased risk of stroke (hazard ratio [HR: 2.29; 95% confidence interval [CI] 1.49-3.52) and death (HR: 2.97; 95% CI 2.25-3.93); with similar rates in different country income levels.Large variations in AF prevalence occur in different regions and country income settings, but this is only partially explained by traditional AF risk factors. Anti-thrombotic therapy is infrequently used in poorer countries despite the high risk of stroke associated with AF.We examined atrial fibrillation (AF) prevalence in 153,152 middle-aged participants spanning 20 countries. Age and sex-standardized prevalence of AF varied by as much as 12-fold between regions; highest in North America, Europe, China and Southeast Asia (270-360 cases per 100,000 persons); and lowest in the Middle East, Africa, and South Asia (30-60 cases per 100,000 persons)(p<0.001); and by as much as 11-fold between groups of countries at different income levels (p<0.001). Global variations were poorly explained by traditional AF risk factors. Future studies are needed to understand the predominant determinants driving the variation in AF burden across different regions of the world.
