Trends in Dual Antiplatelet Therapy of Aspirin and Clopidogrel and Outcomes in Ischemic Stroke Patients Noneligible for POINT/CHANCE Trial Treatment. J Am Heart Assoc 2024; 13:e033611. [PMID: 38761083 DOI: 10.1161/jaha.123.033611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Accepted: 04/15/2024] [Indexed: 05/20/2024]
Abstract
BACKGROUND Recent clinical trials established the benefit of dual antiplatelet therapy with aspirin and clopidogrel (DAPT-AC) in early-presenting patients with minor ischemic stroke. However, the impact of these trials over time on the use and outcomes of DAPT-AC among the patients with nonminor or late-presenting stroke who do not meet the eligibility criteria of these trials has not been delineated. METHODS AND RESULTS In a multicenter stroke registry, this study examined yearly changes from April 2008 to August 2022 in DAPT-AC use for stroke patients ineligible for CHANCE/POINT (Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events/Platelet-Oriented Inhibition in New TIA and Minor Ischemic Stroke) clinical trials due to National Institutes of Health Stroke Scale >4 or late arrival beyond 24 hours of onset. A total of 32 118 patients (age, 68.1±13.1 years; male, 58.5%) with National Institutes of Health Stroke Scale of 4 (interquartile range, 1-7) were analyzed. In 2008, DAPT-AC was used in 33.0%, other antiplatelets in 62.7%, and no antiplatelet in 4.3%. The frequency of DAPT-AC was relatively unchanged through 2013, when the CHANCE trial was published, and then increased steadily, reaching 78% in 2022, while other antiplatelets decreased to 17.8% in 2022 (Ptrend<0.001). From 2011 to 2022, clinical outcomes nonsignificantly improved, with an average relative risk reduction of 2%/y for the composite of stroke, myocardial infarction, and all-cause mortality, both among patients treated with DAPT-AC and patients treated with other antiplatelets. CONCLUSIONS Use of DAPT-AC in stroke patients with stroke ineligible for recent DAPT clinical trials increased markedly and steadily after CHANCE publication in 2013, reaching deployment in nearly 4 of every 5 patients by 2022. The secondary prevention in patients with ischemic stroke seems to be gradually improving, possibly due to the enhancement of risk factor control.

Abstract
BACKGROUND AND OBJECTIVES Understanding trends in the use of medications for secondary stroke prevention is crucial for identifying areas for improvement in stroke care. We examined the use of lipid-lowering, antihypertensive, glucose-lowering, oral anticoagulant, and antiplatelet medications after ischemic stroke hospitalization, from 2005 to 2021. METHODS Using nationwide registries in Denmark, we identified a cohort of patients discharged from hospital with a first-time or recurrent ischemic stroke (N = 150,744). Stratified by calendar year, we ascertained the 180-day probability of filling a prescription for the abovementioned medications after discharge. We further assessed factors associated with medication use. RESULTS From 2005 to 2021, lipid-lowering medication use increased from 58.3% to 82.0%; atorvastatin use rose from 2.1% to 64.8% and simvastatin use decreased from 55.7% to 8.6%. Antihypertensive medication use remained stable, at approximately 89%, and various antihypertensive classes were used comparably. Glucose-lowering medication use increased from 71.5% in 2005 to 84.1% in 2021, driven primarily by an increase in metformin use (from 28.0% to 59.5%). Use of glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors continually increased (from 1.7% to 17.5% and from 0.5% to 17.3%, respectively) between 2015 and 2021. Anticoagulant medication use rose from 45.9% in 2005 to 87.0% in 2021, primarily because of increased use of direct oral anticoagulant medications starting around 2010 and a decline in warfarin use. Antiplatelet use remained consistently high, at approximately 95%. Trends were consistent across subgroups of interest; however, overall medication use was lower in older patients (65 years and older), patients with severe stroke, and patients with neurologic and psychiatric comorbidities. DISCUSSION Despite increasing trends in the use of 3 of 5 medication classes, the overall use of lipid-lowering, glucose-lowering, and oral anticoagulant medications was somewhat lower than expected according to clinical guidelines, particularly among older patients with more severe stroke and other comorbidities. The relatively low use in these subgroups may signify appropriate clinical decision making in consideration of frequent contraindications and reduced life expectancy or highlight potential areas of improvement for the care of patients with recent ischemic stroke.

Abstract
ABSTRACT We report process outcomes of the pilot randomized controlled trial of Texting 4 Relapse Prevention (T4RP), a text messaging-based relapse prevention program for people with schizophrenia or schizoaffective disorder (SAD). Forty people were randomized to either the intervention or treatment as usual control group at a 2:1 ratio. Process indicators were collected at 6 months post enrollment.Over 90% of patients agreed or strongly agreed that the text messages were easy to understand, easy to answer, positive, and helped them feel supported. Patient acceptability was positively associated with recovery (β = 0.29, p = <0.001) and patient-provider communication scores (β = 1.04, p < 0.001), and negatively associated with symptoms of the disorder (β = -0.27, p = 0.07). Acceptability was similar by diagnosis (β, SAD diagnosis = 0.40, p = 0.90) and age (β = 0.05, p = 0.67). Findings suggest that a text messaging intervention aimed at preventing relapse is feasible and perceived as beneficial in individuals with schizophrenia and SAD. Future research might include a targeted study of T4RP within the context of hospital discharge when people with schizophrenia/SAD are at highest risk of relapse.

Timing of Anticoagulation after Stroke in Patients with Non-Valvular Atrial Fibrillation Assessment of Provider Practices. J Stroke Cerebrovasc Dis 2021; 30:106014. [PMID: 34364012 DOI: 10.1016/j.jstrokecerebrovasdis.2021.106014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 07/12/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Optimal timing of oral anticoagulation (TOAC) in acute ischemic stroke (AIS) in patients with atrial fibrillation (AF) is unknown. The risk of recurrent ischemic events when treatment is delayed is often weighed against that of hemorrhagic transformation (HT) when anticoagulation is started in the subacute phase, especially in moderate to large infarctions. Despite substantial evidence for the benefit of oral anticoagulation (OAC) in reducing stroke recurrence, current nationally recognized practice guidelines do not provide clear recommendations on the TOAC after AF-related AIS. MATERIALS AND METHODS We surveyed neurologists on therapeutic approaches to timing of anticoagulation after stroke in patients with AF (without moderate or severe mitral stenosis or a mechanical heart valve) using an online questionnaire. Several ischemic and hemorrhagic stroke scenarios with various stroke sizes, locations, and high-risk thrombotic complications were presented, and survey respondents were asked to provide post-stroke timeframe for TOAC. Practice background, specialty and years of experience of respondents were recorded. RESULTS Majority of participants favored early initiation of OAC in small infarcts. In moderate to larger infarct burden, or when ischemia was complicated by HT, there was an overall trend to delay any initiation of OAC, irrespective of specialty or years of experience. The overt presence of an additional cardiac embolic source such as cardiac thrombus led decisions for early anticoagulation. CONCLUSION Although general practice trends were captured, optimal TOAC following AIS in AF remains unknown. Further research is warranted to determine optimal timing and anticoagulant selection.

The 2020 breakthroughs in early secondary prevention: dual antiplatelet therapy versus single antiplatelet therapy. Curr Opin Neurol 2021; 34:45-54.

Abstract
PURPOSE OF REVIEW Single antiplatelet therapy represents an established treatment in secondary prevention of ischemic strokes and transient ischemic attacks (TIAs). In contrast with coronary artery disease, the use of dual antiplatelet therapy (DAPT) for secondary prevention in patients with acute cerebral ischemia (ACI) remains under debate. In this narrative review, we present and analyse the most recent findings concerning the potential efficacy and safety of DAPT therapy after ischemic strokes or TIA. RECENT FINDINGS Following the publication of the three (CHANCE, POINT and THALES) large, randomized-controlled, clinical trials (RCTs) that showed efficacy of early DAPT for the secondary prevention after minor AIS or TIA, short-term DAPT use is becoming the most prevalent choice of treatment. Notably, DAPT is even more popular after AIS attributed to large artery atherosclerosis given randomized data from small RCTs supporting the use of DAPT in patients with extracranial or intracranial atherosclerosis and microembolization detected by transcranial Doppler. Recent subanalysis of data from the randomized trials aim to identify specific patient subgroups, which are determined by genetic, imaging or clinical characteristics, and for whom DAPT appears to be more beneficial. The potential role of different antiplatelet agents (aspirin, clopidogrel, ticagrelor) is also discussed. SUMMARY DAPT has recently proven its efficacy for the early secondary prevention of AIS patients with minor stroke severity and high-risk TIA patients. However, the length of DAPT is still controversial, as well as the individualized selection of AIS or TIA patients with the lower risk of bleeding and with the greater benefit in prevention of ischemic cerebrovascular and cardiovascular events.

Adherence to prescription guidelines and achievement of treatment goals among persons with coronary heart disease in Tromsø 7. BMC Cardiovasc Disord 2021; 21:44. [PMID: 33478404 PMCID: PMC7819182 DOI: 10.1186/s12872-021-01866-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 01/13/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Adherence to clinical practice guidelines for coronary heart disease (CHD) reduces morbidity, mortality and treatment costs. We aimed to describe and compare adherence to prescription guidelines for persons with CHD, and explore its association with treatment goal achievement. METHOD We included all participants reporting myocardial infarction, angina, percutaneous coronary intervention and/or coronary artery bypass surgery in the seventh wave of the Tromsø Study (2015-2016, n = 1483). Medication use and treatment goal measures (blood pressure, low-density lipoprotein (LDL)-cholesterol and HbA1c) were compared to clinical practice guidelines on secondary CHD prevention. Propensity score matched logistic regression was used to assess the association between the use of antihypertensive drugs and achievement of treatment goal for blood pressure, and the use of lipid-lowering drugs (LLDs) and achievement of treatment goal for LDL-cholesterol. RESULTS The prevalence of pharmacological CHD treatment was 76% for LLDs, 72% for antihypertensive drugs and 66% for acetylsalicylic acid. The blood pressure goal (< 140/90 mmHg, < 140/80 mmHg if diabetic) was achieved by 58% and the LDL-cholesterol goal (< 1.8 mmol/l or < 70 mg/dL) by 9%. There was a strong association between using LLDs and achieving the treatment goal for LDL-cholesterol (OR 14.0, 95% CI 3.6-54.7), but not between using antihypertensive drugs and blood pressure goal achievement (OR 1.4, 95% CI 0.7-2.7). CONCLUSION Treatment goal achievement of LDL-cholesterol and blood pressure was low, despite the relatively high use of LLDs and antihypertensive drugs. Further research is needed to find the proper actions to increase achievement of the treatment goals.

Assessment of Trends in Statin Therapy for Secondary Prevention of Atherosclerotic Cardiovascular Disease in US Adults From 2007 to 2016. JAMA Netw Open 2020; 3:e2025505. [PMID: 33216139 PMCID: PMC7679951 DOI: 10.1001/jamanetworkopen.2020.25505] [Citation(s) in RCA: 61] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/01/2023] Open
Abstract
IMPORTANCE Atherosclerotic cardiovascular disease (ASCVD) is highly prevalent in the US, with studies indicating substantial rates of nonadherence to and undertreatment with statin therapy. The 2013 American College of Cardiology/American Heart Association guideline recommended high-intensity statins for all patients age 75 years and younger with documented ASCVD in whom such therapy is tolerated, but there is limited evidence documenting population trends of statin use, adherence, and outcomes in the periods before and after the update to the guideline. OBJECTIVE To assess trends in the use, adherence, cost, and outcomes of statin therapy for secondary prevention in patients with different types of ASCVD between 2007 and 2016. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used data from the OptumLab Data Warehouse database containing privately insured and Medicare Advantage enrollees with demographic characteristics similar to the national US population. Participants were adult patients (age ≥21 years) who had their first ASCVD event between January 1, 2007, and December 31, 2016. Data were characterized as belonging to 3 groups: (1) cardiovascular heart disease (CHD); (2) ischemic stroke or transient ischemic attack (TIA); and (3) peripheral artery disease (PAD). Data were analyzed from July 1 to August 1, 2018. EXPOSURES Calendar year of the initial ASCVD event. MAIN OUTCOMES AND MEASURES Trends in the statin use (within 30 days of discharge from hospitalization), adherence (proportion of days covered ≥80% within the first year), cost, major adverse cardiac events (1-year cumulative risk), and statin intolerance (within the first year). RESULTS Of the 284 954 patients with a new ASCVD event, 128 422 (45.1%) were women; the median age was 63 years (interquartile range [IQR], 54-72 years); 207 781 (72.9%) were White. The use of statins increased from 50.3% in 2007 to 59.9% in 2016, the use of high-intensity statins increased from 25.0% to 49.2%, and the adherence increased from 58.7% to 70.5% (P < .001 for all trends). Patients with CHD were more likely to receive statins and high-intensity statins and adhere to medications than patients with ischemic stroke, TIA, or PAD despite similar observed treatment benefit. In 2016, 80.9% of patients with CHD used a statin vs 65.8% of patients with ischemic stroke or TIA and 37.5% of patients with PAD. Out-of-pocket cost per 30-day decreased from a median of $20 (interquartile range, $7.6-$31.9) in 2007 to $2 (interquartile range, $1.6-$10.0) in 2016 (P < .001) with the increasing use of generic statins (42.0% in 2007 vs 94.9% in 2016; P < .001). Major adverse cardiac events decreased from 8.9% in 2007 to 6.5% in 2016 (P < .001) whereas statin intolerance increased from 4.0% to 5.1% (P < .001). CONCLUSIONS AND RELEVANCE There have been modest improvements in the use, adherence, and cardiovascular outcomes over the past decade for statin therapy in patients with ASCVD, but a substantial and persistent treatment gap exists between patients with and without CHD, between men and women.

Abstract
This 6 month randomized control trial investigated whether a novel text-messaging program impacted targeted clinical outcomes in patients with schizophrenia and schizoaffective disorder (SAD). Forty patients were enrolled and completed baseline, 3-month and 6-month assessments. The intervention group received daily symptom check-in text messages, plus, a medication reminder or, inspirational quote text. The control group had treatment as usual. At 6 months the Positive and Negative Syndrome Scale mean positive score was significantly lower and injectable medication compliance was significantly higher in the intervention group. Recovery scores were significantly higher at 3 months. Results suggest that this program may benefit individuals with schizophrenia/SAD who use text messaging. Further investigation in a larger sample appears warranted.

Abstract
BACKGROUND Statin remains a mainstay in the prevention and treatment of cardiovascular diseases. Statin utilization has evolved over time in many countries, but data on this topic from China are quite limited. This study aimed to investigate the changing trends of statins prescription, as well as detail the statin utilization through a successive longitudinal study. METHODS The prescription database was established based on electronic health records retrieved from the hospital information system of Jinshan Hospital, Fudan University from January 2012 to December 2018 in Shanghai, China. The prescription rates and proportions of different statin types and doses among all patients were examined. Sub-analyses were performed when stratifying the patients by age, gender, dose intensity, and preventative intervention. RESULTS During the study period, a total of 51,083 patients, who were prescribed for statins, were included in this study (mean [SD] age, 59.78 [±13.16] years; 53.60% male, n = 27, 378). The overall statins prescription rate in which patients increased from 2012 (1.24, 95% CI: 1.21-1.27%) to 2018 (3.16, 95% CI: 3.11-3.20%), P < 0.001. Over 90% of patients were given a moderate dose of statins. Patients with a history of coronary and cerebrovascular events (over 32%) were more likely to be prescribed with statins for preventative intervention. Furthermore, our study has witnessed a significant rise in statin therapy in primary and secondary prevention. CONCLUSIONS In conclusion, statins were frequently prescribed and steadily increased over time in our study period. There were also changes in statin drug choices and dosages. A coordinated effort among the patient, clinical pharmacist, stakeholders and health system is still needed to improve statin utilization in clinical practice in the future.

Abstract
OBJECTIVE To quantify the implementation of the third Joint British Societies' Consensus Recommendations for the Prevention of Cardiovascular Disease (JBS3) after coronary event. METHODS Using a cross-sectional survey design, patients were consecutively identified in 36 specialist and district general hospitals between 6 months and 2 years, after acute coronary syndrome or revascularisation procedure and invited to a research interview. Outcomes included JBS3 lifestyle, risk factor and therapeutic management goals. Data were collected using standardised methods and instruments by trained study nurses. Blood was analysed in a central laboratory and a glucose tolerance test was performed. RESULTS 3926 eligible patients were invited to participate and 1177 (23.3% women) were interviewed (30% response). 12.5% were from black and minority ethnic groups. 45% were persistent smokers, 36% obese, 52.9% centrally obese, 52% inactive; 30% had a blood pressure >140/90 mm Hg, 54% non-high-density lipoprotein ≥2.5 mmol/L and 44.3% had new dysglycaemia. Prescribing was highest for antiplatelets (94%) and statins (85%). 81% were advised to attend cardiac rehabilitation (86% <60 years vs 79% ≥60 years; 82% men vs 77% women; 93% coronary artery bypass grafting vs 59% unstable angina), 85% attended if advised; 69% attended overall. Attenders were significantly younger (p=0.03) and women were less likely to attend (p=0.03). CONCLUSIONS Patients with coronary heart disease (CHD) are not being adequately managed after event with preventive measures. They require a structured preventive cardiology programme addressing lifestyle, risk factor management and adherence to cardioprotective medications to achieve the standards set by the British Association for Cardiovascular Prevention and Rehabilitation and JBS3 guidelines.

Abstract
UNLABELLED Although Scandinavian countries have the highest incidence of hip fracture in the world, trends in anti-osteoporosis medication use have not been studied. We found less than one-third of Danish hip fracture patients had dispensing of anti-osteoporosis medication over a 10-year period using routinely collected data from population-based registries. INTRODUCTION To examine trend in dispensing of anti-osteoporosis medication before and after hip fracture surgery in Denmark over a 10-year period using routinely collected data from population-based registries. METHODS From the Danish Multidisciplinary Hip Fracture Registry, we included 65,011 patients aged 65 years or older with an incident hip fracture in 2005-2015. We calculated, for each calendar year of hip fracture diagnosis, the prevalence of use of anti-osteoporosis medication (at least one dispensing of bisphosphonates, strontium ranelate, denosumab, selective estrogen receptor modulators, or teriparatide) in the year before and in the year following hip fracture diagnosis. Among those without a dispensing in the year before hip fracture, we computed 1-year cumulative incidence of use following hip fracture. We treated death as a competing risk and stratified the analysis on sex, age, and comorbidity. RESULTS The prevalence of use before hip fracture varied between 7 and 12%, increasing slightly from 2005 to 2015. The cumulative incidence of use following hip fracture decreased from 16% in 2005 to 13% in 2010, whereupon it increased to 20%. A similar pattern was seen with each stratum of sex, age groups, and comorbidity. The overall prevalence of use after hip fracture was below 22% in all calendar years. CONCLUSIONS Less than one-third of hip fracture patients had dispensing of anti-osteoporosis medication up to 1 year after hip fracture. We observed only a slight increase in dispensing after hip fracture over the study period, irrespective of patient sex, age, and comorbidity at the time of hip fracture.

Abstract
The objective of this study was to use qualitative methodology to tailor and refine an existing smoking cessation intervention for the population of people who use cigarettes and are diagnosed with schizophrenia, schizoaffective, or psychotic disorder. Successive cohort design methodology was used to iteratively modify the treatment in response to qualitative participant, therapist, and consultant feedback on the intervention. Qualitative methodology for participant feedback included analysis of semistructured interviews with participants, visualization of app utilization data, and stakeholder feedback from study therapists and consultants. Using the successive cohort design, a tailored multicomponent mobile health smoking cessation intervention was developed. The intervention included mobile contingency management (i.e., financial compensation for confirmed abstinence from smoking), pharmacotherapy for smoking cessation, cognitive-behavioral counseling sessions, and the Stay Quit app for relapse prevention. Two cohorts (N = 13) were completed in the study; after each cohort, the treatment protocol was revised. The intervention is described, as well as the qualitative findings from each cohort and subsequent changes made to the intervention based upon patient and provider feedback. Metrics of patient engagement included treatment adherence (40% in Cohort 1 and 63% in Cohort 2). Both participants and therapists reported that the intervention was helpful. Over one third of participants self-reported abstinence at posttreatment. Since qualitative methodology is often underutilized in mental health treatment development, this study demonstrates the utility of the successive cohort design for treatment development of behavior change interventions for at-risk, vulnerable populations.

Abstract
Recent changes in American and European guidelines on the management of arterial hypertension have caused a considerable shift in the landscape of hypertension management. The 2017 American College of Cardiology/American Heart Association/American Society of Hypertension guideline recommends an office visit blood pressure (BP) > 130/80 mmHg as the new threshold for diagnosis of hypertension, and states that the treatment goal for all hypertensive patients should be lowered to < 130/80 mmHg. In contrast, the 2018 European guideline maintains the diagnostic threshold of hypertension at 140/90 mmHg. However, despite their differences in thresholds for diagnosis of hypertension, both guidelines are in agreement that treatment should be considered in patients with BPs in the range of 130 to 139/80 to 89 mmHg if they have high cardiovascular risk. The results from the Systolic Blood Pressure Intervention Trial (SPRINT) study and recent meta-analyses suggest that BP lowering with antihypertensive treatment may be beneficial in reducing cardiovascular event rates in subjects with high-normal BP or stage 1 hypertension according to the new American guideline. However, intensive BP lowering is associated with increased incidence of treatment-associated adverse events, and evidence suggests that BP lowering below 120/70 mmHg increases the risk of cardiovascular events. In this review, we discuss the evidence supporting antihypertensive treatment in subjects with high-normal BP and discuss the specific subgroup of subjects that might benefit from BP lowering.

Abstract
BACKGROUND Our objective is to estimate the effects associated with higher rates of renin-angiotensin system antagonists, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARBs), in secondary prevention for geriatric (aged >65 years) patients with new ischemic strokes by chronic kidney disease (CKD) status. METHODS AND RESULTS The effects of ACEI/ARBs on survival and renal risk were estimated by CKD status using an instrumental variable (IV) estimator. Instruments were based on local area variation in ACEI/ARB use. Data abstracted from charts were used to assess the assumptions underlying the instrumental estimator. ACEI/ARBs were used after stroke by 45.9% and 45.2% of CKD and non-CKD patients, respectively. ACEI/ARB rate differences across local areas grouped by practice styles were nearly identical for CKD and non-CKD patients. Higher ACEI/ARB use rates for non-CKD patients were associated with higher 2-year survival rates, whereas higher ACEI/ARB use rates for patients with CKD were associated with lower 2-year survival rates. While the negative survival estimates for patients with CKD were not statistically different from zero, they were statistically lower than the estimates for non-CKD patients. Confounders abstracted from charts were not associated with the instrumental variable used. CONCLUSIONS Higher ACEI/ARB use rates had different survival implications for older ischemic stroke patients with and without CKD. ACEI/ARBs appear underused in ischemic stroke patients without CKD as higher use rates were associated with higher 2-year survival rates. This conclusion is not generalizable to the ischemic stroke patients with CKD, as higher ACEI/ARBS use rates were associated with lower 2-year survival rates that were statistically lower than the estimates for non-CKD patients.

Abstract
OBJECTIVES The authors sought to describe the incidence, determinants, and outcome of elective coronary revascularization (ECR) in patients with stable coronary artery disease (CAD). BACKGROUND Observational data are lacking regarding the practice of ECR in patients with stable CAD receiving modern secondary prevention. METHODS The authors analyzed coronary revascularization procedures performed during a 5-year follow-up in 4,094 stable CAD outpatients included in the prospective multicenter CORONOR (Suivi d'une cohorte de patients COROnariens stables en région NORd-Pas-de-Calais) registry. RESULTS Secondary prevention medications were widely prescribed at inclusion (antiplatelet agents 96.4%, statins 92.2%, renin-angiotensin system antagonists 81.8%). A total of 481 patients underwent ≥1 coronary revascularization procedure (5-year cumulative incidences of 3.6% [0.7% per year] for acute revascularizations and 8.9% [1.8% per year] for ECR); there were 677 deaths during the same period. Seven baseline variables were independently associated with ECR: prior coronary stent implantation (p < 0.0001), absence of prior myocardial infarction (p < 0.0001), higher low-density lipoprotein cholesterol (p < 0.0001), lower age (p < 0.0001), multivessel CAD (p = 0.003), diabetes mellitus (p = 0.005), and absence of treatment with renin-angiotensin system antagonists (p = 0.020). Main indications for ECR were angina associated with a positive stress test (31%), silent ischemia (31%), and angina alone (25%). The use of ECR had no impact on the subsequent risk of death, myocardial infarction, or ischemic stroke (hazard ratio: 1.04; 95% confidence interval: 0.76 to 1.41). CONCLUSIONS These real-life data show that ECR is performed at a rate of 1.8% per year in stable CAD patients widely treated by secondary medical prevention. ECR procedures performed in patients without noninvasive stress tests are not rare. Having an ECR was not associated with the risk of ischemic adverse events.

Abstract
Cardiovascular disease (CVD) remains the number one cause of death in women. It is estimated that 44 million women in the United States are either living with or at risk for heart disease. This article highlights the recent significant progress made in improving care, clinical decision-making, and policy implications for women with CVD. We provide our perspective supported by evidence-based advances in cardiovascular research and clinical care guidelines in seven areas: (1) primary CVD prevention and community heart care, (2) secondary prevention of CVD, (3) stroke, (4) heart failure and cardiomyopathies, (5) ischemia with nonobstructive coronary artery disease, (6) spontaneous coronary artery dissection, and (7) arrhythmias and device therapies. Advances in these fields have improved the lives of women living with and at risk for heart disease. With increase awareness, partnership with national organizations, sex-specific research, and changes in policy, the morbidity and mortality of CVD in women can be further reduced.

Abstract
OBJECTIVE To determine the proportion of patients receiving statins for primary or secondary prevention of cardiovascular disease (CVD), as well as to describe lipid-screening trends. DESIGN Retrospective chart review using the Manitoba Primary Care Research Network repository. SETTING Manitoba. PARTICIPANTS A total of 149 262 patients. MAIN OUTCOME MEASURES Proportion of patients who were taking statins for primary or secondary prevention of cardiovascular disease (CVD), who did not have evidence of CVD recorded in their charts, and who underwent lipid screening; distribution of statins among age groups; and the proportion of patients eligible for lipid screening when the age cutoffs of the 2012 and 2016 Canadian Cardiovascular Society guidelines were applied. RESULTS Of the 149 262 patients, 139 025 (93%) did not have CVD recorded in their electronic medical records and made up the primary prevention group; of these 139 025 patients, 5955 (4%) were taking statins. Also in the primary prevention group, 14 814 (11%) patients were 75 years of age and older; of these patients, 1374 (9%) were taking statins. A total of 10 237 of the 149 262 (7%) patients had CVD recorded in their charts (secondary prevention group); 3013 (29%) of these patients were taking statins. When the 2016 Canadian Cardiovascular Society guidelines age cutoffs were applied, 56% of patients (83 119 of 149 262) were eligible for lipid screening, and 31% (26 024 of 83 119) of them had evidence of screening in the past 5 years. Of the total population of those aged 75 and older, 28% (5597 of 20 188) had undergone lipid screening. Of the total population taking statins, 28% (2481 of 8968) had undergone lipid testing while taking statins. CONCLUSION In Manitoba, less than 5% of the primary prevention population and less than 30% of the secondary prevention population had received repeat statin prescriptions from their primary care providers. This represents a possible practice gap that warrants future research, as statins offer considerable morbidity and mortality benefits in these patients.

Abstract
AIMS To audit the management of ST-segment elevation myocardial infarction (STEMI) patients admitted to a New Zealand Hospital over three 14-day periods to review their number, characteristics, management and outcome changes over a decade. METHODS The acute coronary syndrome (ACS) audits were conducted over 14 days in May of 2002, 2007 and 2012 at New Zealand Hospitals admitting patients with a suspected or definite ACS. Longitudinal analyses of the STEMI subgroup are reported. RESULTS From 2002 to 2012, the largest change in management was the proportion of patients undergoing reperfusion by primary PCI from 3% to 15% and 41%; P<0.001, and the rates of second antiplatelet agent use in addition to aspirin from 14% to 62% and 98%; P<0.001. The use of proven secondary prevention medications at discharge also increased during the decade. There were also significant increases in cardiac investigations for patients, especially echocardiograms (35%, 62% and 70%, P<0.001) and invasive coronary angiograms (31%, 58% and 87%, P<0.001). Notably even in 2012, one in four patients presenting with STEMI did not receive any reperfusion therapy. CONCLUSIONS Substantial improvements have been seen in the management of STEMI patients in New Zealand over the last decade, in accordance with evidenced-based guideline recommendations. However, there appears to be considerable room to optimise management, particularly with the use of timely reperfusion therapy for more patients.

Decline in Cardiovascular Mortality: Possible Causes and Implications. Circ Res 2017; 120:366-380.

Abstract
If the control of infectious diseases was the public health success story of the first half of the 20th century, then the decline in mortality from coronary heart disease and stroke has been the success story of the century's past 4 decades. The early phase of this decline in coronary heart disease and stroke was unexpected and controversial when first reported in the mid-1970s, having followed 60 years of gradual increase as the US population aged. However, in 1978, the participants in a conference convened by the National Heart, Lung, and Blood Institute concluded that a significant recent downtick in coronary heart disease and stroke mortality rates had definitely occurred, at least in the US Since 1978, a sharp decline in mortality rates from coronary heart disease and stroke has become unmistakable throughout the industrialized world, with age-adjusted mortality rates having declined to about one third of their 1960s baseline by 2000. Models have shown that this remarkable decline has been fueled by rapid progress in both prevention and treatment, including precipitous declines in cigarette smoking, improvements in hypertension treatment and control, widespread use of statins to lower circulating cholesterol levels, and the development and timely use of thrombolysis and stents in acute coronary syndrome to limit or prevent infarction. However, despite the huge growth in knowledge and advances in prevention and treatment, there remain many questions about this decline. In fact, there is evidence that the rate of decline may have abated and may even be showing early signs of reversal in some population groups. The National Heart, Lung, and Blood Institute, through a request for information, is soliciting input that could inform a follow-up conference on or near the 40th anniversary of the original landmark conference to further explore these trends in cardiovascular mortality in the context of what has come before and what may lie ahead.

Abstract
Despite the introduction of anti-inflammatory drugs that selectively inhibit cyclo-oxygenase-2 (COX-2), and potent inhibitors of gastric acid secretion, the gastrointestinal adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs) remain a significant clinical problem. Combined use of antisecretory drugs and COX-2 inhibitors is helpful to limit the damage in the proximal gastrointestinal tract (stomach and duodenum), but it increases the risk of injury of small intestine and colon. It was proven that proton pump inhibitors and H2 receptor antagonists significantly worsen NSAID-induced small intestinal damage and microbiota balance. Nowadays, there is no proven effective preventative or curative treatment for NSAID-induced enteropathy. The new strategy of gastrointestinal protection is based on the discovery of endogenous cytoprotective molecules such as hydrogen sulfide (H₂S). H2S is a gaseous mediator that produces strong cytoprotective and antioxidant effect on the gastrointestinal tract. The role of H₂S in promoting mucosal integrity, healing of tissue injury and resolution of inflammation has been well documented. In addition, H₂S stimulates productions of other cytoprotective molecules including prostaglandins, carbon monoxide and nitric oxide. Nowadays, the new generation of H₂S-releasing non-steroidal anti-inflammatory drugs is developed and tested in clinical trials. H₂S-NSAIDs possess enhanced anti-inflammatory activity and high gastrointestinal safety.

Abstract
BACKGROUND The aim of this study was to determine overall and aetiology-related incidence of secondary prevention ICD implantation over the last 15years in Canton Ticino and to assess clinical outcome according to time period of implantation. METHODS AND RESULTS Consecutive patients treated by implantation of an ICD for secondary prevention from 2000 to 2015 were included in the current study and compared between 5-year cohorts (2000/2004; 2005/2009; 2010/2015). Yearly implantation rate, changing in clinical presentation over years and events during follow-up were evaluated. One-hundred fifty six patients were included. ICD implantation rate increased from 2.1 in 2000-2005 to 5.1 in 2010-2015, respectively (p 0.001). There was an increase in the proportion of non-ischaemic patients and of ventricular tachycardia (VT) as presenting rhythm. No differences in appropriate ICD interventions were observed according to aetiology, presenting arrhythmia or type of device. Reverse remodelling was observed more often in non-ischaemic patients, without any influence on the occurrence of appropriate interventions. Previous myocardial infarction (MI), atrial fibrillation (AF), NYHA class 2-3 and left ventricular ejection fraction (LVEF)<35% were predictors of appropriate therapies during follow-up. CONCLUSIONS Rate of implants for secondary prevention indication has almost doubled during the last 15years. Importantly, there has been a progressive increase of non-ischaemic patients receiving an ICD, and of VT as presenting rhythm. Patients had an overall good survival and a relatively low incidence of appropriate therapies. Improvement of ejection fraction did not correlate with risk reduction of ventricular arrhythmias.

Abstract
Mantle cell lymphoma (MCL) represents the fourth most common type of non-Hodgkin lymphomas. It is characterized by aggressive course and frequent relapses. The main aim of this review is to evaluate current treatment approach towards this type of lymphoma. In younger patients the chemotherapy including high doses of cytarabine is the gold standard. In case of complete or partial remission, the consolidation with autologous stem cell transplantation is indicated as consolidation approach. In older patients CHOP-R regimen is not the treatment of choice. These patients should be treated with bendamustine in combination with rituximab. In case of complete or partial remission, further therapy with rituximab maintenance as consolidation represents an option. The vast majority of patients with MCL will ultimately relapse which poses a challenge in treatment approach. The approach in relapsed MCL can be divided in two types: chemotherapy or biologic therapy. In young fit patients chemotherapy based on bendamustine and cytarabine is a reasonable option. In patients with comorbidities or poor performance status biologic agents are reasonable options. Ibrutinib, Bruton kinase inhibitor, is characterized by highest overall response rate and the longest duration of response and should be offered to these patients. With the development of novel potent inhibitor of B cell receptor signaling pathway, these agents may become the gold standard in future and introduce the treatment of MCL in „chemo-free“era.

Abstract
Naltrexone is an antagonist that binds tightly to μ-opioid receptors and blocks the subjective and analgesic effects of opioids. It does not produce physiologic dependence and precipitates withdrawal if administered to an opioid dependent person, thus starting it must begin with detoxification. It was first available in the mid-1970s as a 50 mg tablet that blocked opioids for 24-36 h if taken daily, or every 2-3 days at higher doses - for example: 100 mg Monday and Wednesday, 150 mg on Friday. From a pharmacological perspective it worked very well and was hoped to be an effective treatment but results were disappointing due to low patient interest and high dropout followed by relapse. Interest in it waned but rose again in the late 1990's when injecting opioid use and the rapid spread of HIV in the Russian Federation converged with an international interest in reducing the spread of HIV. One result was a series of meetings sponsored by the U.S. National Institute on Drug Abuse (NIDA) and Pavlov State Medical University in St. Petersburg, Russian Federation, on ways to reduce the spread of HIV in that country. Addiction treatment was a clear priority and discussions showed that naltrexone could have a role since agonist treatment is against Russian law but naltrexone is approved and the government funds over 25,000 beds for detoxification, which is the first step in starting naltrexone treatment. These meetings were followed by NIDA studies that showed better compliance to oral naltrexone than in prior U.S. studies with the expected reductions in HIV injecting risk for those that stayed in treatment. These events and findings provided a background and identified an infrastructure for the study that led to FDA approval of extended release injectable naltrexone for preventing relapse to opioid dependence. This paper will briefly review findings from these studies and end with comments on the potential role of extended release naltrexone as a meaningful addition to current pharmacotherapies for treating opiod dependence and reducing HIV risk.

Abstract
Liver transplantation (LT) is a considerably effective treatment for patients with end-stage hepatitis B virus (HBV)-related liver disease. However, HBV infection often recurs after LT without prophylaxis. Since the 1990s, the treatment for preventing HBV reinfection after LT has greatly progressed with the introduction of hepatitis B immunoglobulin (HBIG) and nucleos(t)ide analogues (NAs), resulting in improved patient survival. The combination therapy consisting of high-dose HBIG and lamivudine is highly efficacious for preventing the recurrence of HBV infection after LT and became the standard prophylaxis for HBV recurrence. However, mainly due to the high cost of HBIG treatment, an alternative protocol for reducing the dose and duration of HBIG has been evaluated. Currently, combination therapy using low-dose HBIG and NAs is considered as the most efficacious and cost-effective prophylaxis for post-LT HBV reinfection. Recently, NA monotherapy and withdrawal of HBIG from combination therapy, along with the development of new, potent high genetic barrier NAs, have provided promising efficacy, especially for low-risk recipients. This review summarizes the prophylactic protocol and their efficacy including prophylaxis of de novo HBV infection from anti-HBc antibody-positive donors. In addition, challenging approaches such as discontinuation of all prophylaxis and active immunity through hepatitis B vaccination are discussed.

Abstract
BACKGROUND This cross-sectional, questionnaire-based survey, conducted in Shanxi Province, China, evaluated the knowledge of community physicians of secondary prevention of ischemic stroke and transient ischemic attacks (TIAs). METHODS A total of 1910 physicians practicing at 832 community-based clinics, hospitals and other care centers in 11 prefectures of Shanxi Province completed the questionnaires between 1 July and 30 September 2013. RESULTS Over 90 % of participants were aware of the most common risk factors for stroke, but lifestyle-related factors were seen as of low or medium importance for secondary prevention. Only about 50 % of physicians were aware of the existence of commonly used stroke scales, and fewer said that they would use those scales in their clinical practice. There were slight differences in the responses to some of the questions on risk factors and stroke scales were associated with the physicians' gender, academic qualifications, practice duration and location. Less than half of the participants were aware of the secondary prevention recommendations included in the most recent guidelines. CONCLUSION The survey revealed a huge gap in knowledge of current guidelines for secondary prevention of ischemic stroke and TIA among the physicians surveyed. Continuing education and training of community physicians, administered as a public health program, is needed to improve the healthcare of ischemic stroke and TIA patients.

Abstract
UNLABELLED The probability of initiating with anti-osteoporosis therapy increased from 7 % in 2000 to 46 % in 2010. This improvement was greater for patients over the age of 75 years. Men, those overweight, having dementia or exposed to antipsychotics, sedatives/hypnotics or opioid analgesics were significantly less likely to receive anti-osteoporosis drugs. INTRODUCTION The objective of this study was to examine trends and determinants of anti-osteoporosis drug prescribing after hip fracture in the UK between 2000 and 2010. METHODS Data were extracted from the UK Clinical Practice Research Datalink for patients ≥50 years who had a first hip fracture between 2000 and 2010 and who did not currently (≤6 months prior) receive anti-osteoporosis drugs (bisphosphonates, strontium ranelate, parathyroid hormone, calcitonin and raloxifene) (n = 27,542). The cumulative incidence probability of being prescribed anti-osteoporosis drugs within 1 year after hip fracture was estimated by Kaplan-Meier life-table analyses. Determinants for treatment initiation were estimated by Cox proportional hazards models. RESULTS The probability of being prescribed any anti-osteoporosis drug after hip fracture increased from 7 % in 2000 to 46 % in 2010. This trend was more marked in patients ≥75 years. The increase in prescribing of anti-osteoporosis drugs was complemented by a similar increase in vitamin D/calcium provision. Cumulative incidence of receiving anti-osteoporosis therapy was greater at any given point in time in women (8 % in 2000, 51 % in 2010) compared to men (4 % in 2000, 34 % in 2010). In addition to male gender, multivariable Cox regression identified reduced likelihood of receiving anti-osteoporosis drugs for those being overweight, having dementia and exposed to psychotropic drugs (antipsychotics, sedatives/hypnotics) or opioid analgesics. CONCLUSION Although the prescribing of anti-osteoporosis drugs after hip fracture has increased substantially since 2000, the overall rate remained inadequate, particularly in men. With the continuing increase in the absolute number of hip fractures, further research should be made into the barriers to optimise osteoporosis management.

Abstract
BACKGROUND Nationally representative data evaluating recent trends and future projections of vascular risk factor treatment and control rates in secondary prevention of ischemic heart disease are sparse. METHODS AND RESULTS We evaluated sex- and race-stratified cholesterol, blood pressure, and hemoglobin A1c levels and risk factor treatment and control rates in 1580 individuals who self-reported a history of myocardial infarction from The National Health and Nutrition Examination Surveys (NHANES) 1999 to 2012. We used weighted linear regression to estimate time trends and created forward linear projections to 2020. Participants were 30% to 41% women, 73% to 85% white, and had a mean age of 63 to 66 years. Cholesterol treatment rates increased and reached above 80% in men and women by 2011-2012, with significant increases in control rates (as then defined) in men to 85% in 2011-2012, with projections to reach 100% by 2020. Cholesterol treatment rates significantly increased in non-Hispanic whites and Hispanics. Statin use increased significantly to 73% of myocardial infarction survivors by 2011-2012, and aspirin use increased significantly but only to 28% by 2011-2012. There were no changes in blood pressure treatment or control rates by sex, and hypertension treatment increased only in non-Hispanic blacks. Projected hypertension control rates remained suboptimal. CONCLUSIONS While temporal trends suggest improvements in cholesterol treatment, unchanged treatment and control of blood pressure and persistently low aspirin use represent missed opportunities. Urgent action is needed to improve secondary prevention rates projected by 2020 to reduce recurrent events in this high-risk group.

Abstract
Suicide is not only a contradictory biological, psychological, sociocultural and spiritual phenomenon, but also a serious public health problem, which is manifold, therefore the fight against it is also complex. The aim of the present publication is to establish the current situation of the fight against suicide in Hungary, which are the most important deficits, contradictions and unexploited possibilities. The author states that although we have accomplished important steps in the prevention of suicide, we did not realise the majority of them in everyday practice. The author defines the most important problems and tasks which should be solved in the next decade. In the near future a great deal more should be done for prevention than what we have accomplished so far in order to significantly reduce the number of suicide victims in Hungary.

Abstract
Incidences of fragility fractures, such as of the vertebral and hip, increase with age. Both the number and severity of prevalent vertebral fractures involve independent risk factors for future fractures. However, it has been reported that the vast majority of patients who experience fragility fractures do not receive anti-osteoporotic therapy. Among patients who begin anti- osteoporosis treatment after fracture, adherence to treatment remains suboptimal. The recent development of anti-osteoporosis drugs has revolutionized the field of fracture prevention by reducing risk more than 50%. A consensus of systematic and multidisciplinary approaches to secondary fragility fracture prevention, called the Fracture (Osteoporosis) Liaison Service, has been developed over the last decade.

Abstract
AIM Aim of the study was to assess the effect of socioeconomic deprivation on prescribing of cardiovascular secondary prevention medications in patients referred with peripheral arterial disease (PAD). METHODS A retrospective review of vascular clinic referrals was performed. All patients referred from primary care with suspected PAD over a two month period were included. The deprivation score, prescription of cardiovascular secondary prevention medications, smoking status and the presence of cardiovascular co-morbidities (coronary artery or cerebrovascular disease--CAD/CVD) were assessed. Comparison was made between socioeconomic groups using the Carstairs Deprivation (DepCat) Score and between patients with and without a history of currently existing cardiovascular co-morbidities. RESULTS The study included 391 patients. Almost two thirds of patients (253) were from the most deprived socioeconomic groups and were significantly younger at presentation (median age DepCat 7: 63 yrs, DepCat 1-2: 74.5 yrs, P<0.0001). The majority of patients with a prior history of CAD/CVD were prescribed secondary preventative medications at the time of referral with suspected PAD whereas those with no prior history of CAD/CVD, (212 patients, 54%) were significantly less likely to be prescribed antiplatelets (47% vs. 83%), statins (45% vs. 86%) or ACEi/ARBs (29% vs. 68%) (all P<0.05). Secondary prevention prescribing did not differ between socioeconomic groups. CONCLUSION Secondary prevention prescribing is inadequate in patients with suspected PAD regardless of socioeconomic group and is significantly lower in those without previously diagnosed CAD/CVD. There remains a lack of appreciation of the high cardiovascular risk associated with PAD.

Abstract
BACKGROUND guidelines have changed in relation to the indication of antiplatelet therapy for the primary and secondary prevention of stroke. Of interest is how the proportion of patients who had or had not taken antiplatelet agents prior to an incident stroke has changed over time, whether the type of antiplatelet agents used has altered and whether prior antiplatelet use is associated with a particular ischaemic stroke subtype. METHODS a stroke register was retrospectively examined. All ischaemic stroke patients admitted between January 2004 and March 2011 to a single University Hospital with a catchment population of ∼750,000 were included. We excluded those who were on anticoagulants prior to the ischaemic stroke. RESULTS a total of 4,307 ischaemic stroke patients [male 47.5%, mean age 77.6 (SD 11.7) years] were included. Of them, 54.7% (SD 2.2%) were not on any antiplatelet therapy prior to their incident stroke. The type and pattern of antiplatelet use prior to stroke did not change significantly during the 7-year study period, and there were no statistically significant differences between different ischaemic stroke subtypes with regards to prior antiplatelet use. CONCLUSIONS our findings highlight the requirement to improve currently available risk prediction scores as well as the potential clinical impact of antiplatelet resistance within the at risk population who are already on antiplatelets. These findings also indicate that targeting of multiple risk factors may be very important in stroke prevention.

Abstract
Fracture Liaison Services (FLS) have been demonstrated in many countries to provide an effective means to deliver secondary preventive care for patients presenting with fragility fractures. This review provides an update on journal articles, reports, guidelines and government policies, with relevance to FLS, which have been published during the period 2009-2012. International evidence of the extent and persistence of the secondary fracture prevention care gap has expanded during this period. Major professional and patient societies throughout the world, including the International Osteoporosis Foundation and the American Society for Bone and Mineral Research, have supported international initiatives to disseminate best practice. Health economic analysis of FLS has developed considerably, with a consistent theme from investigator-led and government analyses that FLS provide highly cost-effective care. Opportunities to close the care gap, in a systematic way, for unrecognised vertebral fracture sufferers are also considered.

Rationale and current perspective for early rhythm control therapy in atrial fibrillation. Europace 2011; 13:1517-25.

Abstract
Atrial fibrillation (AF) is the most common sustained arrhythmia and an important source for mortality and morbidity on a population level. Despite the clear association between AF and death, stroke, and other cardiovascular events, there is no evidence that rhythm control treatment improves outcome in AF patients. The poor outcome of rhythm control relates to the severity of the atrial substrate for AF not only due to the underlying atrial remodelling process but also due to the poor efficacy and adverse events of the currently available ion-channel antiarrhythmic drugs and ablation techniques. Data suggest, however, an association between sinus rhythm maintenance and improved survival. Hypothetically, sinus rhythm may also lead to a lower risk of stroke and heart failure. The presence of AF, thus, seems one of the modifiable factors associated with death and cardiovascular morbidity in AF patients. Patients with a short history of AF and the underlying heart disease have not been studied before. It is fair to assume that abolishment of AF in these patients is more successful and possibly also safer, which could translate into a prognostic benefit of early rhythm control therapy. Several trials are now investigating whether aggressive early rhythm control therapy can reduce cardiovascular morbidity and mortality and increase maintenance of sinus rhythm. In the present paper we describe the background of these studies and provide some information on their design.

Abstract
OBJECTIVE Data on long-term use of secondary prevention medications following stroke are limited. The Adherence eValuation After Ischemic stroke-Longitudinal (AVAIL) Registry assessed patient, provider, and system-level factors influencing continuation of prevention medications for 1 year following stroke hospitalization discharge. METHODS Patients with ischemic stroke or TIA discharged from 106 hospitals participating in the American Heart Association Get With The Guidelines-Stroke program were surveyed to determine their use of warfarin, antiplatelet, antihypertensive, lipid-lowering, and diabetes medications from discharge to 12 months. Reasons for stopping medications were ascertained. Persistence was defined as continuation of all secondary preventive medications prescribed at hospital discharge, and adherence as continuation of prescribed medications except those stopped according to health care provider instructions. RESULTS Of the 2,880 patients enrolled in AVAIL, 88.4% (2,457 patients) completed 1-year interviews. Of these, 65.9% were regimen persistent and 86.6% were regimen adherent. Independent predictors of 1-year medication persistence included fewer medications prescribed at discharge, having an adequate income, having an appointment with a primary care provider, and greater understanding of why medications were prescribed and their side effects. Independent predictors of adherence were similar to those for persistence. CONCLUSIONS Although up to one-third of stroke patients discontinued one or more secondary prevention medications within 1 year of hospital discharge, self-discontinuation of these medications is uncommon. Several potentially modifiable patient, provider, and system-level factors associated with persistence and adherence may be targets for future interventions.

Secondary prevention after coronary artery bypass graft surgery: findings of a national randomized controlled trial and sustained society-led incorporation into practice. Circulation 2011; 123:39-45.

Abstract
BACKGROUND Despite evidence supporting the use of aspirin, β-blockers, angiotensin-converting enzyme inhibitors, and lipid-lowering therapies in eligible patients, adoption of these secondary prevention measures after coronary artery bypass grafting has been inconsistent. We sought to rigorously test on a national scale whether low-intensity continuous quality improvement interventions can be used to speed secondary prevention adherence after coronary artery bypass grafting. METHODS AND RESULTS A total of 458 hospitals participating in the Society of Thoracic Surgeons National Cardiac Database and treating 361 328 patients undergoing isolated coronary artery bypass grafting were randomized to either a control or an intervention group. The intervention group received continuous quality improvement materials designed to influence the prescription of the secondary prevention medications at discharge. The primary outcome measure was discharge prescription rates of the targeted secondary prevention medications at intervention versus control sites, assessed by measuring preintervention and postintervention site differences. Prerandomization treatment patterns and baseline data were similar in the control (n=234) and treatment (n=224) groups. Individual medication use and composite adherence increased over 24 months in both groups, with a markedly more rapid rate of adherence uptake among the intervention hospitals and a statistically significant therapy hazard ratio in the intervention versus control group for all 4 secondary prevention medications. CONCLUSIONS Provider-led, low-intensity continuous quality improvement efforts can improve the adoption of care processes into national practice within the context of a medical specialty society infrastructure. The findings of the present trial have led to the incorporation of study outcome metrics into a medical society rating system for ongoing quality improvement.

Abstract
Effective disease management after an acute coronary event is essential, but infrequently implemented, due to challenges around the research evidence and its translation. Policy-makers, health professionals and researchers are confronted by the need for increased services, to improve access and equity, but often with finite and reducing resources. There is a clear need to develop innovative ways of delivering ongoing preventative care to the vast and increasing population with coronary disease. However, translation into clinical practice is becoming increasingly difficult while the volume of trial and review evidence of disparate models of delivery expands. Indeed, the prevention literature has evolved into a complex web of differing models offered to diverse patient populations in an array of settings. We describe a united organisation of care that aims to facilitate coordinated secondary prevention for all in need (SPAN). SPAN is inherently flexible yet provides a minimum level of health service standardisation. It can be delivered across any area health service regardless of a patient's age, gender, ethnicity, geographical location, or socioeconomic status. Importantly, the setting, communication technologies and components of each patient's care are governed and woven into continuing care provided by the family physician in concert with a cardiac care facilitator.

Abstract
To evaluate the achievement of health care services in Korea independent of other socioeconomic factors, we observed the time trend of avoidable death between 1983 and 2004. A list of avoidable causes of death was constructed based on the European Community Atlas of "Avoidable Death". We calculated sex- and age-standardized mortality rates of Korean aged 1-64 yr using data of the Korea National Statistical Office. The avoidable mortality rate (per 100,000 persons) decreased from 225 to 84 in men and from 122 to 41 in women. Accordingly, the proportion of avoidable deaths among all classifiable deaths was reduced by 8.1% in men and 6.4% in women. However, mortality rates from some preventable causes such as ischemic heart disease and malignant neoplasms of lung, breast, cervix, and colorectum have been on the rise. Mortality preventable by appropriate medical care showed the greatest reduction (by 77.8%), while the mortality preventable by primary prevention showed the least reduction (by 50.0%). These findings suggest that health care service has significantly contributed to the improvement of health in Korea. However, more effective intervention programs would be needed given the less reduction in mortality avoidable by primary or secondary prevention than expected and unexpectedly increasing mortality from several preventable causes.
