Effect of a Cardiovascular Polypill on Poststroke Cognition Among Ghanaians: Secondary Analysis of a Randomized Clinical Trial.

BACKGROUND: Poststroke cognitive impairment is prevalent worldwide, with no satisfactory preventative therapeutic strategies. We report on the effect of a cardiovascular polypill on cognitive performance among recent stroke survivors. METHODS AND RESULTS: The SMAART (Stroke Minimization through Additive Anti-atherosclerotic Agents in Routine Treatment) trial was a phase II randomized trial primarily assessing the polypill versus usual care for secondary prevention after a recent ischemic stroke. Participants allocated to the experimental arm were provided 2 Polycaps taken orally once a day for 12 months. A capsule of Polycap contained aspirin 100 mg, simvastatin 20 mg, hydrochlorothiazide 12.5 mg, ramipril 5 mg, and atenolol 50 mg. Participants in the usual care arm received standard secondary prevention therapy. We compared slopes of the trajectory of raw scores in the executive, language, memory, and visuospatial cognitive domains and aggregated cognitive scores over 12 months via a linear mixed-effects model. We enrolled 148 eligible participants (n=74 in each arm) and 59 versus 64 participants in the polypill and usual care arms, respectively, at month 12. Compared with the usual care arm, the slopes of cognitive performance over 12 months in the polypill arm were steeper by 2.02 units (95% CI, 0.52-3.53), P=0.009 in executive domain, 1.88 units (95% CI, 0.42-3.34), P=0.012 in language domain, 2.60 (0.03-5.17), P=0.049 in memory domain, 0.55 (-0.80 to 1.91), P=0.42 in the visuospatial domain, and global cognitive performance 6.87 units (95% CI, 1.44-12.30), P=0.013. CONCLUSIONS: The cardiovascular polypill is associated with a signal of better cognitive performance over 12 months among stroke survivors. Further definitive trials are warranted.

Efficacy and Safety of Propranolol vs Atenolol in Infants With Problematic Infantile Hemangiomas: A Randomized Clinical Trial.

Importance: Propranolol has become the first-line therapy for problematic infantile hemangiomas (IHs) that require systemic therapy. However, different adverse events have been reported during propranolol treatment. The positive efficacy and safety of atenolol raise the question of whether it could be used as a promising therapy for IH. Objective: To compare the efficacy and safety of propranolol vs atenolol in infants (between age 5 and 20 weeks) with problematic IHs who required systemic therapy. Design, Setting, and Participants: This was a prospective, multicenter, randomized, controlled, open-label clinical trial conducted in collaboration among 6 separate investigation sites in China from February 1, 2015, to December 31, 2018. A total of 377 patients met the criteria for inclusion and were randomized to the propranolol (190 [50.4%]) and atenolol (187 [49.6%]) groups. Data were analyzed in June 2020. Interventions: Participants were randomized to receive either propranolol or atenolol for at least 6 months. They completed efficacy assessments at 2 years after the initial treatment. Main Outcomes and Measures: The primary outcome was any response or nonresponse at 6 months. The key secondary outcome was changes in the hemangioma activity score. Results: Of 377 participants, 287 (76.1%) were female, and the mean (SD) age was 10.2 (4.0) weeks in the propranolol group and 9.8 (4.1) weeks in the atenolol group. After 6 months of treatment, in the propranolol and atenolol groups, the overall response rates were 93.7% and 92.5%, respectively (difference, 1.2%; 95% CI, -4.1% to 6.6%). At 1 and 4 weeks after treatment, and thereafter, the hemangioma activity score in the atenolol group aligned with the propranolol group (odds ratio, 1.034; 95% CI, 0.886-1.206). No differences between the propranolol group and atenolol group were observed in successful initial responses, quality of life scores, complete ulceration healing times, or the rebound rate. Both groups presented a similar percentage of complete/nearly complete responses at 2 years (82.1% vs 79.7%; difference, 2.4%; 95% CI, -5.9% to 10.7%). Adverse events were more common in the propranolol group (70.0% vs 44.4%; difference, 25.6%; 95% CI, 15.7%-34.8%), but the frequency of severe adverse events did not differ meaningfully between the groups. Conclusions and Relevance: In this randomized clinical trial, when compared with propranolol, atenolol had similar efficacy and fewer adverse events in the treatment of infants with problematic IHs. The results suggest that oral atenolol can be used as an alternative treatment option for patients with IH who require systemic therapy.

Polypill with or without Aspirin in Persons without Cardiovascular Disease.

BACKGROUND: A polypill comprising statins, multiple blood-pressure-lowering drugs, and aspirin has been proposed to reduce the risk of cardiovascular disease. METHODS: Using a 2-by-2-by-2 factorial design, we randomly assigned participants without cardiovascular disease who had an elevated INTERHEART Risk Score to receive a polypill (containing 40 mg of simvastatin, 100 mg of atenolol, 25 mg of hydrochlorothiazide, and 10 mg of ramipril) or placebo daily, aspirin (75 mg) or placebo daily, and vitamin D or placebo monthly. We report here the outcomes for the polypill alone as compared with matching placebo, for aspirin alone as compared with matching placebo, and for the polypill plus aspirin as compared with double placebo. For the polypill-alone and polypill-plus-aspirin comparisons, the primary outcome was death from cardiovascular causes, myocardial infarction, stroke, resuscitated cardiac arrest, heart failure, or revascularization. For the aspirin comparison, the primary outcome was death from cardiovascular causes, myocardial infarction, or stroke. Safety was also assessed. RESULTS: A total of 5713 participants underwent randomization, and the mean follow-up was 4.6 years. The low-density lipoprotein cholesterol level was lower by approximately 19 mg per deciliter and systolic blood pressure was lower by approximately 5.8 mm Hg with the polypill and with combination therapy than with placebo. The primary outcome for the polypill comparison occurred in 126 participants (4.4%) in the polypill group and in 157 (5.5%) in the placebo group (hazard ratio, 0.79; 95% confidence interval [CI], 0.63 to 1.00). The primary outcome for the aspirin comparison occurred in 116 participants (4.1%) in the aspirin group and in 134 (4.7%) in the placebo group (hazard ratio, 0.86; 95% CI, 0.67 to 1.10). The primary outcome for the polypill-plus-aspirin comparison occurred in 59 participants (4.1%) in the combined-treatment group and in 83 (5.8%) in the double-placebo group (hazard ratio, 0.69; 95% CI, 0.50 to 0.97). The incidence of hypotension or dizziness was higher in groups that received the polypill than in their respective placebo groups. CONCLUSIONS: Combined treatment with a polypill plus aspirin led to a lower incidence of cardiovascular events than did placebo among participants without cardiovascular disease who were at intermediate cardiovascular risk.

Multicap to improve adherence after acute coronary syndromes: results of a randomized controlled clinical trial.

BACKGROUND: Adherence to treatment after a myocardial infarction (MI) is poor, even in the early postinfarction period. Combining evidence-based drugs into a multicap could improve adherence in this population. No previous randomized trial assessing fixed-dose combination therapy has included patients early after a MI. We aimed to assess if a multicap containing four secondary prevention drugs increases adherence to treatment at 6 months after MI hospitalization. The study was designed as a randomized, parallel, open-label, controlled trial. METHODS: Patients were randomized within 7 days of a MI to either multicap or control group. The multicap group received a capsule containing aspirin, atenolol, ramipril, and simvastatin. The control group received each drug in separate pills. The primary outcome was adherence at 6 months. We also measured blood pressure, heart rate, serum cholesterol levels, C-reactive protein, and platelet aggregation. RESULTS: The study was stopped prematurely when 100 patients were included for futility. At 6 months, 92 (95.8%) patients were adherent to medical treatment: 98.0% in the multicap group and 93.5% in the control group [relative risk (RR) 1.05; 95% confidence interval (CI) 0.96-1.14; p = 0.347]. There were no differences between groups in systolic blood pressure (p = 0.662), diastolic blood pressure (p = 0.784), heart rate (p = 0.533), total cholesterol (p = 0.760), LDL-c (p = 0.979), C-reactive protein (p = 0.399), or in the proportion of patients with adequate platelet aggregation inhibition (p = 0.600). CONCLUSIONS: The study did not find any improvement in the adherence at 6 months after a MI with a multicap-based strategy (Multicap for Increase Adherence After Acute Myocardial Infarction; [ ClinicalTrials.gov identifier: NCT02271178]).

Oral Atenolol for Infantile Hemangioma: Case Series of 46 Infants. / Atenolol oral en el manejo del hemangioma infantil: serie de casos de 46 pacientes.

Propranolol, a non-selective beta-blocker, remains the first line of treatment for problematic infantile hemangioma. However, although rarely, a subset of patients experience undesirable side effects, raising interest in other selective beta-blockers. We present a large case series of 46 infants treated successfully with oral atenolol, a selective beta-1 blocker.

The International Polycap Study-3 (TIPS-3): Design, baseline characteristics and challenges in conduct.

BACKGROUND: It is hypothesized that in individuals without clinical cardiovascular disease (CVD), but at increased CVD risk, a 50% to 60% reduction in CVD risk could be achieved using fixed dose combination (FDC) therapy (usually comprised of multiple blood-pressure agents and a statin [with or without aspirin]) in a single "polypill". However, the impact of a polypill in preventing clinical CV events has not been evaluated in a large randomized controlled trial. METHODS: TIPS-3 is a 2x2x2 factorial randomized controlled trial that will examine the effect of a FDC polypill on major CV outcomes in a primary prevention population. This study aims to determine whether the Polycap (comprised of atenolol, ramipril, hydrochlorothiazide, and a statin) reduces CV events in persons without a history of CVD, but who are at least at intermediate CVD risk. Additional interventions in the factorial design of the study will compare the effect of (1) aspirin versus placebo on CV events (and cancer), (2) vitamin D versus placebo on the risk of fractures, and (3) the combined effect of aspirin and the Polycap on CV events. RESULTS: The study has randomized 5713 participants across 9 countries. Mean age of the study population is 63.9 years, and 53% are female. Mean INTERHEART risk score is 16.8, which is consistent with a study population at intermediate CVD risk. CONCLUSION: Results of the TIP-3 study will be key to determining the appropriateness of FDC therapy as a strategy in the global prevention of CVD.

Influence of Aortic Stiffness on Aortic-Root Growth Rate and Outcome in Patients With the Marfan Syndrome.

The Pediatric Heart Network randomized trial of atenolol versus losartan in the Marfan syndrome showed no treatment differences in the rates of aortic-root growth or clinical outcomes. In this report we present treatment effects on aortic stiffness and determine whether baseline aortic stiffness predicts aortic-root growth and clinical outcomes. Echocardiograms at 0, 6, 12, 24, and 36 months from 608 subjects (6 months to 25 years) who met original Ghent criteria and had a maximum aortic-root z-score (ARz) >3 were centrally reviewed. Stiffness index (SI) and elastic modulus (EM) were calculated for aortic root and ascending aorta. Data were analyzed using multivariable mixed effects modeling and Cox regression. Heart rate-corrected aortic-root SI over 3 years decreased with atenolol but did not change with losartan (-0.298 ± 0.139 vs 0.141 ± 0.139/year, p = 0.01). In the entire cohort, above-median aortic-root SI (>9.1) and EM (>618 mm Hg) predicted a smaller annual decrease in ARz (p ≤0.001). Upper-quartile aortic-root EM (>914 mm Hg) predicted the composite outcome of aortic-root surgery, dissection, or death (hazard ratio 2.17, 95% confidence interval 1.02 to 4.63, p = 0.04). Crude 3-year event rates were 10.4% versus 3.2% for higher versus lower EM groups. In conclusion, atenolol was associated with a decrease in aortic-root SI, whereas losartan was not. Higher baseline aortic-root SI and EM were associated with a smaller decrease in ARz and increased risk for clinical outcomes. These data suggest that noninvasive aortic stiffness measures may identify patients at higher risk of progressive aortic enlargement and adverse clinical outcomes, potentially allowing for closer monitoring and more aggressive therapy.

Cardioversion of a supraventricular tachycardia (SVT) in a 7-year-old using a postural modification of the Valsalva manoeuvre.

A boy aged 7 years presented with his parents to the emergency department (ED). He had a known diagnosis of paroxysmal supraventricular tachycardia (SVT) and was under the care of paediatricians. He had been suffering episodes of palpitations and chest pain for over a year and had been prescribed atenolol 25 mg ON, though the side effects meant he had not taken it for a month prior to presentation. He had 2 previous confirmed episodes of SVT, one that reverted with Valsalva manoeuvres, and the other with intravenous adenosine. In the ED, an ECG was recorded showing SVT at 180 bpm. Aside from his tachycardia, he was haemodynamically stable. The postural modification of the Valsalva technique was performed within 5 min of arrival, with reversion to sinus rhythm occurring during the leg-lift phase on the first attempt. After 30 min of observation, the child remained stable and was discharged home.

Impact of switching from different treatment regimens to a fixed-dose combination pill (polypill) in patients with cardiovascular disease or similarly high risk.

Aims Cardiovascular fixed-dose combination pills, or polypills, may help address the widespread lack of access and adherence to proven medicines. Initiation of polypill-based care typically entails switching from current separately taken medications. Given the heterogeneity in usual care, there is interest in the impact of polypill treatment across different patterns of prior medication regimen. Methods A total of 2004 participants with established cardiovascular disease or estimated 5-year cardiovascular risk of over 15% were randomised to polypill-based treatment (aspirin 75 mg, simvastatin 40 mg, lisinopril 10 mg and either atenolol 50 mg or hydrochlorothiazide 12.5 mg) or usual care. Baseline medications were classified by potency relative to polypill components. Estimated cardiovascular risk reduction was calculated by combining risk factor changes with results seen in meta-analyses of previous randomised trials. Results For cholesterol reduction conferred by polypills, there was a dose response across baseline statin groups, with mean low-density lipoprotein (LDL)-cholesterol differences of 0.37, 0.22, 0.14 and 0.07 mmol/L among patients taking no statin, less potent, equipotent and more potent statin at baseline, respectively. Similarly there were differences in mean systolic BP of 5.4, 6.2, 3.3 and 1.8 mmHg among patients taking 0, 1, 2 or 3 BP-lowering agents. Among patients taking more potent statins at baseline, there was no significant difference in LDL-cholesterol but there were benefits for BP and aspirin adherence. Similar results were seen among patients taking 3 BP-lowering agents at baseline. Switching to a polypill-based strategy resulted in estimated cardiovascular relative risk reductions across a wide range of usual care patterns of antiplatelet, statin and BP-lowering therapy prescribing. Conclusion Adherence benefits from switching to a polypill resulted in risk factor changes that were at least as good as usual care across a wide variety of treatment patterns, including equally potent or more potent regimens. The benefits of switching to polypill-based care were greatest among those stepped up from partial treatment or less potent treatment.

Oral atenolol therapy for proliferating infantile hemangioma: A prospective study.

Propranolol, a lipophilic nonselective ß-blocker, has recently been reported to be the treatment of choice for select types of infantile hemangiomas (IHs). Atenolol is a hydrophilic, selective ß1-blocker and therefore may be not associated with side effects attributable to ß2-adrenergic receptor blockade and lipophilicity. However, the efficacy and safety of atenolol in the treatment of IH are poorly understood. The aim of this study was to evaluate the efficacy and safety of atenolol in the treatment of proliferating IHs.A study of 76 infants between the ages of 5 to 20 weeks with superficial or mixed IH was conducted between August 2013 and March 2015. Oral atenolol was administered in a progressive schedule to 1 mg/kg per day in a single dose. Efficacy was assessed using the Hemangioma Activity Score (HAS) at weeks 0, 1, 4, 12, and 24. Safety was evaluated at weeks 0, 1, 4, 8, 12, 16, 20, and 24.In total, 70 patients completed 24 weeks of treatment. IH growth abruptly stopped for 93.4% of patients within the fourth week of treatment with atenolol. In ulcerated IHs, complete healing of the ulcerations occurred in an average treatment time of 5.5 weeks. Atenolol treatment promoted dramatic decreases in HAS scores after week 1. An "excellent" treatment response (compete or nearly complete resolution of the IH) was observed in 56.5% of patients at week 24. No significant hypoglycemia, bronchospasm, bradycardia, or hypotension occurred. The most common adverse event was diarrhea, followed by agitation and sleep disturbance.This study demonstrated that atenolol was effective and safe at a dose of 1 mg/kg per day for 24 weeks in the treatment of proliferating IHs.

Impact of achieved systolic blood pressure on renal function in hypertensive patients.

Aims: There is strong evidence for the association of high blood pressure (BP) with depressed renal function. Although high BP at baseline is associated with greater progression of chronic kidney disease (CKD), randomized trials in CKD patients have found no significant relationship between more intensive BP control and glomerular filtration rate (GFR) decline. However, the relationship of GFR and change in GFR over time to lower achieved systolic BP (SBP) in hypertensive patients undergoing treatment is unclear. Methods and results: Baseline estimated GFR (eGFR) and change in eGFR during follow-up were examined in relation to average on-treatment SBP in 8778 hypertensive patients with ECG left ventricular hypertrophy (LVH) randomly assigned to losartan- or atenolol-based treatment. GFR was estimated using the Modification of Diet in Renal Disease study equation. Patients with average on-treatment SBP ≤130 mmHg (lowest quintile at last measurement) and average SBP between 131 and 141 mmHg were compared with patients with average SBP ≥142 mmHg (median SBP at last measurement). Patients with an average on-treatment SBP ≤130 mmHg had significantly lower baseline eGFR than those with average SBP between 131 and 141 or average SBP ≥142 mmHg (65.5 ± 14.3 vs. 69.3 ± 14.3 vs. 69.0 ± 14.5 mL/min/1.73 m2, P < 0.001 using analysis of covariance adjusting for age, sex, race, randomized treatment, prior antihypertensive treatment, history of diabetes, myocardial infarction, ischaemic heart disease or heart failure, smoking status, baseline serum glucose, total and HDL cholesterol, albuminuria, and baseline LVH by Cornell product and Sokolow-Lyon voltage). However, the decrease in eGFR between baseline and Year 4 was significantly lower among patients with average SBP ≤130 mmHg (-6.3 ± 10.3 vs. -7.9 ± 11.1 vs. -9.2 ± 10.6 mL/min/1.73 m2, P = 0.001 when adjusting for the same variables and for change in Cornell product and Sokolow-Lyon voltage between baseline and Year 4). These differences in eGFR change persisted even after adjusting for baseline eGFR, and there were no significant interactions with randomized treatment, sex, race, or baseline presence of proteinuria. Conclusion: Lower average on-treatment SBP (≤130 mmHg) was associated with a lower baseline eGFR but with a slower reduction in eGFR during 4-year follow-up in hypertensive patients with ECG LVH, independent of other possible risk factors for decreased GFR. Further study is necessary to determine whether randomized treatment to lower SBP goals is more protective of renal function than treatment to standard SBP goals.

Characterization of silicone pressure-sensitive adhesive episcleral implant for drug delivery.

The development of an effective sustained ocular drug delivery system remains a challenging task. The objective of the present study was to characterize a silicone pressure sensitive adhesive (PSA) episcleral implant system for transscleral drug delivery. Silicone PSA implants for dexamethasone, atenolol, and bovine serum albumin (BSA) were prepared at different polymer-to-drug mass ratios. Implant adhesion to human cadaver sclera was measured. Drug release experiments were conducted in well-stirred containers in vitro. The results were then analyzed using a pharmacokinetic model and in vitro-in vivo data comparison from previous studies. The silicone PSA episcleral implants in the present study had an average diameter of 3.5 mm and a thickness of 0.8 mm. Drug release from the silicone PSA implants was influenced by drug solubility, implant polymer content, and implant coating. Drug release from the implants was observed to follow the receding boundary release mechanism and was solubility dependent with the higher water solubility drug showing higher release rate than the low-solubility drug. Increasing polymer content in the implants led to a significant decrease in the drug release rate. Coated implants reduced the initial burst effect and provided lower release rates than the uncoated implants. These implants provided sustained drug release that could last up to several months in vitro and demonstrated the potential to offer drug delivery for chronic ocular diseases via the transscleral route.

Beta-blockers for childhood vascular tumors.

PURPOSE OF REVIEW: Since 2008, beta-blockers have become first-line treatment for infantile hemangiomas, the most common tumor of infancy. Their role is also being explored in the treatment of other childhood vascular tumors. RECENT FINDINGS: Recent research has demonstrated that propranolol is a more effective and safer treatment for infantile hemangiomas than previous therapeutic options. It is most effective when initiated during the tumor's proliferative phase. Other oral beta-blockers such as atenolol and nadolol are less studied, but may offer similar efficacy. Topical beta-blockers such as timolol appear to be effective in treating small, superficial infantile hemangiomas. Beta-blockers have shown variable results for the treatment of other vascular tumors of childhood, such as pyogenic granulomas, kaposiform hemangioendotheliomas, and tufted angiomas. SUMMARY: Propranolol has revolutionized the treatment of infantile hemangiomas, and other beta-blockers provide promising alternatives. Unanswered questions remain about the optimal choice of agent, delivery mechanism, dosage, need for pretreatment evaluation or ongoing monitoring, and duration of therapy. The role of beta-blockers in treating other types of vascular tumors requires further study.

The Effects of Oral Atenolol or Enalapril Premedication on Blood Loss and Hypotensive Anesthesia in Orthognathic Surgery.

PURPOSE: The aim of this study was to evaluate the effects of premedication with oral atenolol or enalapril, in combination with remifentanil under sevoflurane anesthesia, on intraoperative blood loss by achieving adequate deliberate hypotension (DH) during orthognathic surgery. Furthermore, we investigated the impact thereof on the amount of nitroglycerin (NTG) administered as an adjuvant agent. MATERIALS AND METHODS: Seventy-three patients undergoing orthognathic surgery were randomly allocated into one of three groups: an angiotensin converting enzyme inhibitor group (Group A, n=24) with enalapril 10 mg, a ß blocker group (Group B, n=24) with atenolol 25 mg, or a control group (Group C, n=25) with placebo. All patients were premedicated orally 1 h before the induction of anesthesia. NTG was the only adjuvant agent used to achieve DH when mean arterial blood pressure (MAP) was not controlled, despite the administration of the maximum remifentanil dose (0.3 µg kg⁻¹ min⁻¹) with sevoflurane. RESULTS: Seventy-two patients completed the study. Blood loss was significantly reduced in Group A, compared to Group C (adjusted p=0.045). Over the target range of MAP percentage during DH was significantly higher in Group C than in Groups A and B (adjusted p-values=0.007 and 0.006, respectively). The total amount of NTG administered was significantly less in Group A than Group C (adjusted p=0.015). CONCLUSION: Premedication with enalapril (10 mg) combined with remifentanil under sevoflurane anesthesia attenuated blood loss and achieved satisfactory DH during orthognathic surgery. Furthermore, the amount of NTG was reduced during the surgery.

Two cases of cardiac sarcoidosis in pregnant women with supraventricular arrhythmia.

We present two cases of cardiac sarcoidosis whose first presentation was in pregnancy. All findings confirmed the diagnosis of sarcoidosis with cardiac involvement in both patients. The first patient, a 37-year-old, presented with dizziness and atrial fibrillation at 16 weeks' gestation. Echocardiography revealed thickened interventricular septum with a speckled pattern. Cardiac MRI after delivery showed myocardial oedema/inflammation corresponding with the same regions with early enhancement and epicardial delayed enhancement in the basal to mid-inferoseptal and basal anterior left ventricular myocardial segments. Transbronchial biopsy revealed histology of scanty fragments of inflamed bronchial mucosa. The second patient, a 31-year-old, was 17 weeks pregnant when she presented with daily palpitations and shortness of breath. She had prolonged episodes of supraventricular tachycardia. Echocardiography revealed a speckled septal and right ventricular wall pattern. Cardiac MRI after delivery showed basal and mid-ventricular mesocardial and epicardial enhancement, most compatible with sarcoidosis.

A pragmatic randomized trial of a polypill-based strategy to improve use of indicated preventive treatments in people at high cardiovascular disease risk.

BACKGROUND: Most individuals at high cardiovascular disease (CVD) risk worldwide do not receive any or optimal preventive drugs. We aimed to determine whether fixed dose combinations of generic drugs ('polypills') would promote use of such medications. METHODS: We conducted a randomized, open-label trial involving 623 participants from Australian general practices. Participants had established CVD or an estimated five-year CVD risk of ≥15%, with indications for antiplatelet, statin and ≥2 blood pressure lowering drugs ('combination treatment'). Participants randomized to the 'polypill-based strategy' received a polypill containing aspirin 75 mg, simvastatin 40 mg, lisinopril 10 mg and either atenolol 50 mg or hydrochlorothiazide 12.5 mg. Participants randomized to 'usual care' continued with separate medications and doses as prescribed by their doctor. Primary outcomes were self-reported combination treatment use, systolic blood pressure and total cholesterol. RESULTS: After a median of 18 months, the polypill-based strategy was associated with greater use of combination treatment (70% vs. 47%; relative risk 1.49, (95% confidence interval (CI) 1.30 to 1.72) p < 0.0001; number needed to treat = 4.4 (3.3 to 6.6)) without differences in systolic blood pressure (-1.5 mmHg (95% CI -4.0 to 1.0) p = 0.24) or total cholesterol (0.08 mmol/l (95% CI -0.06 to 0.22) p = 0.26). At study end, 17% and 67% of participants in polypill and usual care groups, respectively, were taking atorvastatin or rosuvastatin. CONCLUSION: Provision of a polypill improved self-reported use of indicated preventive treatments. The lack of differences in blood pressure and cholesterol may reflect limited study power, although for cholesterol, improved statin use in the polypill group counter-balanced use of more potent statins with usual care.
