Optimal medical therapy, clinical outcome and its predictors in patients with acute coronary syndrome after discharge with secondary prevention medications at University of Gondar Comprehensive Specialized Hospital, North West Ethiopia, 2023: A retrospective follow-up study

BackgroundThe life-threatening diseases known as ACS (acute coronary syndrome) continue to produce considerable rates of morbidity and mortality despite breakthroughs in therapy. The study determined clinical outcome and its predictors in patients at the University of Gondar Comprehensive and Specialized Hospital (UOGCSH), North West Ethiopia.Design, setting, and participantsA retrospective cohort study design was employed at UOGCSH from January 31, 2018 to February 1, 2023. The hospital used a systematic random sampling procedure to select study participants from the medical records of patients in chronic cardiac follow-up clinics.Main outcome measuresExposures were optimal medical therapy (OMT) versus non-optimal medical therapy collected from May to August 2023. Descriptive and analytical statistics were employed to compare study groups. A binary logistic regression model was employed to identify candidate variables for further analysis. Cox's proportional hazard model and log-rank test were employed, with a P-value < 0.05 used to evaluate statistical significance. A five-year all-cause mortality after discharge estimate was displayed by using Kaplan–Meier curves.ResultsAmong 422 patients with ACS [mean age, 61.56 (SD = 9.686) years; 54.7% male], of whom only 59.2% (250) received optimal medical therapy at discharge. Age ≥ 65, atrial fibrillation, chronic kidney diseases, and cardiogenic shock were negative independent predictors of optimal medical therapy. On the other hand, male sex was independently associated with the use of optimal medical therapy. All-cause mortality occurred in 16.6% (n = 70) and major adverse cardiac events occurred in 30.8% (n = 130) of patients with a 95% CI of 0.132–0.205 and 0.264–0.355, respectively. Multivariate analyses indicated that OMT was significantly associated with reduced all-cause mortality (aHR: 0.431, 95% CI: 0.222–0.835; P = 0.013).ConclusionThis study revealed that the use of preventive OMT in patients discharged with acute coronary syndrome was associated with a reduction in all-cause mortality. However, the use of this OMT is suboptimal.

Adherence to Secondary Preventative Medications One Year Post Stroke

Abstract Background Adherence to secondary preventative medications is critical to reduce subsequent vascular events after ischaemic stroke. Many stroke risk factors are modifiable, but adherence is poor in up to 40% of stroke survivors. Guidelines recommend the use of antithrombotic, lipid lowering and antihypertensive medication. We examined adherence to these medications one year post stroke. Methods This was a retrospective cohort study of patients admitted to an Irish level 3 hospital with an acute stroke between July 2022 and June 2023. Stroke survivors were interviewed a year after stroke onset, either in clinic or in their home, and asked to show the interviewer all current medications. Adherence to three categories of secondary prevention medications and knowledge of their indication was assessed. Results 172 stroke patients were contacted and 64% agreed to participate. The cohort included 62% males and average age was 69.9 years. The majority (72/110, 65%) had a modified Rankin score (mRS) of 0-2. The proportion of participants reporting full adherence to all prescribed medications was 81% (89/110) with adherence rates of 81% for lipid lowering agents and 88% for both antithrombotics and antihypertensives. Adherence was higher in participants who had an involved caregiver (85.9% vs 73.9%) and in those with mRS &amp;gt;2 (94.9% vs 73.2%). There was no significant difference between age or gender subgroups. Knowledge of the indication was 62% for antithrombotics and 55% for lipid-lowering drugs. Conclusion Self-reported adherence to secondary preventative medications was high in this cohort but one in five stroke survivors reported poor adherence increasing their risk for recurrent stroke. Adherence was highest for antithrombotics and lowest for lipid-lowering drugs. Adherence is higher in more dependent individuals and helped by an involved caregiver. We observed a deficit in patient understanding of secondary prevention medications. Improving this knowledge gap could increase adherence to secondary prevention post stroke.

Trends in hip fracture rates in US male veterans.

In the United States, the annual incidence of osteoporotic hip fracture is estimated to be 250,000 to 300,000; the one-year mortality in some studies has been as high as 32%. Reports that hip fracture rates in US women 65years and older may no longer be declining led to this investigation of hip fracture in men, a less studied population. We assessed the trends in the incidence of hip fracture in US male veterans 50years and older of age as well as the rates of diagnosis and treatment in such men. We assessed the recent trends of hip fracture incidence in a nation-wide male veteran population 50years and older of age. Using data from the US Veterans Affairs Informatics and Computing Infrastructure (VINCI) 2002-2019, we calculated the annual age-standardized hip fracture incidence. Secondary objectives included evaluating the annual proportion of hip fracture patients who underwent dual-energy X-ray absorptiometry (DXA) before or after the fracture and/or received osteoporosis medication after the hip fracture over the study period. Hip fracture incidence increased in male veterans from 2006 to 2019. Fewer than 6% of men underwent a DXA scan and fewer than 0.5% received osteoporosis medications up to two years after a hip fracture. Despite available screening methods such as DXAs and medications for primary and secondary prevention of osteoporotic fractures, hip fracture incidence is not decreasing in older male veterans. Our study highlights a need for closerattention to fracture risk in men.

Use of Cardiovascular Disease Secondary Prevention Medications in Four Middle East Countries in a Community Setting.

Evidence-based International clinical practice guidelines, universally recommend secondary prevention medications for those with previous cardiovascular disease (CVD). There is limited data on the community use of these medications in the Middle East (ME). This study assesses the use and predictors of evidence based secondary prevention medications in individuals with a history of CVD [coronary heart disease (CHD) or stroke]. Between 2005 and 2015, we enrolled 11,228 individuals aged between 35-70 years from 52 urban and 35 rural communities from four ME countries, United Arab Emirates (n = 1499), Kingdom of Saudi Arabia (n = 2046), Occupied Palestinian Territory (n = 1668) and Islamic Republic of Iran (n = 6013). With standardized questionnaires, we report estimates of medication use in those with CVD at national level and the independent predictors of their utilization through a multivariable analysis model. Results: Of the total ME cohort, 614 (5.5%) had CVD, of which 115 (1.0%) had stroke, 523 (4.7%) had CHD and 24 (0.2%) had both. The mean age of those with CVD was 56.6 ± 8.8 years and 269 (43.8%) were female. Overall, only 23.5% of those with CVD reported using three or more proven secondary prevention medications, and a substantial proportion (stroke 27.8%, CHD 25.8%) did not take any of these medications. In a fully adjusted analysis, increasing age, female gender, higher education, higher wealth in individual household, residence in a higher income country as well as being obese, hypertensive or diabetic were independent predictors of medication use. The use of secondary prevention medication is low in ME and has not reached the modest recommended WHO target of 50% use of 3 or more medications. Independent factors of higher use were, better socioeconomic status (household wealth, country wealth and education) and better contact and accessibility to health care (increasing age, female gender, obesity, diabetes and hypertension).

Adherence to Secondary Prevention Measures after Acute Myocardial Infarction and Its Impact on Patient Outcome-A Nationwide Perspective.

Objectives: Secondary prevention is crucial for reducing morbidity and mortality in patients following acute myocardial infraction (MI). However, adherence to cardiac rehabilitation (CR) and pharmacotherapy remains suboptimal despite strong guideline recommendations. This study investigated the adherence to CR, dual antiplatelet therapy (DAPT), and statins following acute MI and evaluated their impact on patient outcomes from a nationwide perspective in Austria. Methods: In this national observational study, all patients diagnosed with acute MI, defined as STEMI or NSTEMI, between April 2011 and August 2015 in Austria were included. Patient characteristics and comorbidities were derived from the Austrian national health insurance system using ICD-10 codes. Adherence to CR, high-intensity statins, and DAPT was assessed based on health insurance records and pharmacy prescription submissions. Cox Regression hazard analysis was used to explore the impact of non-adherence to CR on mortality. Results: Among 16,518 acute MI patients, only 13.4% adhered to the recommended CR programs, which was associated with a significantly lower risk of mortality (adjusted hazard ratio [HR] 0.73; 95% CI: 0.54-0.98; p = 0.036). In contrast, 66.4% of 23,240 patients did not comply with high-intensity statin therapy, correlating with an increased mortality risk (adjusted HR 1.16; 95% CI: 1.06-1.25; p < 0.001). Furthermore, among 22,331 patients analyzed for DAPT adherence, only 29.3% followed the guidelines, yet this adherence was linked to a 21% reduction in mortality over the observation period (adjusted HR 0.79; 95% CI: 0.72-0.88; p < 0.001). Conclusions: This nationwide study reveals alarmingly low adherence to CR and secondary preventive medications among acute MI patients, which is significantly linked to higher mortality rates. Enhanced efforts to promote awareness and adherence are crucial, involving structured referrals and personalized follow-ups to improve patient outcomes. Addressing these gaps through comprehensive healthcare strategies could substantially enhance cardiovascular health.

Incidence and Outcomes of Cardiocerebral Infarction: A Cohort Study of 2 National Population-Based Registries.

Cardiocerebral infarction (CCI), which is concomitant with acute myocardial infarction (AMI) and acute ischemic stroke (AIS), is a rare but severe presentation. However, there are few data on CCI, and the treatment options are uncertain. We investigated the characteristics and outcomes of CCI compared with AMI or AIS alone. We performed a retrospective cohort study of 120 531 patients with AMI and AIS from the national stroke and AMI registries in Singapore. Patients were categorized into AMI only, AIS only, synchronous CCI (same-day), and metachronous CCI (within 1 week). The primary outcome was all-cause mortality, and the secondary outcome was cardiovascular mortality. The mortality risks were compared using Cox regression. Multivariable models were adjusted for baseline demographics, clinical variables, and treatment for AMI or AIS. Of 127 919 patients identified, 120 531 (94.2%) were included; 74 219 (61.6%) patients had AMI only, 44 721 (37.1%) had AIS only, 625 (0.5%) had synchronous CCI, and 966 (0.8%) had metachronous CCI. The mean age was 67.7 (SD, 14.0) years. Synchronous and metachronous CCI had a higher risk of 30-day mortality (synchronous: adjusted HR [aHR], 2.41 [95% CI, 1.77-3.28]; metachronous: aHR, 2.80 [95% CI, 2.11-3.73]) than AMI only and AIS only (synchronous: aHR, 2.90 [95% CI, 1.87-4.51]; metachronous: aHR, 4.36 [95% CI, 3.03-6.27]). The risk of cardiovascular mortality was higher in synchronous and metachronous CCI than AMI (synchronous: aHR, 3.03 [95% CI, 2.15-4.28]; metachronous: aHR, 3.41 [95% CI, 2.50-4.65]) or AIS only (synchronous: aHR, 2.58 [95% CI, 1.52-4.36]; metachronous: aHR, 4.52 [95% CI, 2.95-6.92]). In synchronous CCI, AMI was less likely to be managed with PCI and secondary prevention medications (P<0.001) compared with AMI only. Synchronous CCI occurred in 1 in 200 cases of AIS and AMI. Synchronous and metachronous CCI had higher mortality than AMI or AIS alone.

Five-year trend in secondary prevention medication prescription and risk factor control among patients with diabetes mellitus and cardiovascular diseases in Perak health clinics.

Prescription of secondary prevention medications (SPMs) and effective control of cardiovascular risk factors (RFs) are crucial to reduce the risk of recurrent cardiovascular events, particularly in high-risk individuals including those with diabetes mellitus (DM). This study aimed to analyse the trends in SPM prescription and identify the factors associated with RF control among patients with DM and cardiovascular diseases in Perak health clinics. Data of patients with ischaemic heart disease (IHD) and cerebrovascular diseases (CeVDs) audited from 2018 to 2022, excluding those lost to follow-up, were extracted from the National Diabetes Registry. Descriptive and trend analyses were conducted. Multivariable logistic regression was utilised to identify the factors associated with RF control. Most patients (76.7%) were aged ≥60 years and were Malays (62.3%). The majority had IHD (60.8%) and CeVDs (54.7%) for ≥5 years. SPM prescription increased significantly over the past 5 years. However, blood pressure (BP) and lipid control remained static. Good BP control was associated with a DM duration of ≥10 years and poor control with Malay ethnicity and prescription of two or three antihypertensives. Good DM control was associated with an age of ≥60 years and age at DM diagnosis of ≥60 years and poor control with Malay and Indian ethnicities, DM duration of ≥10 years and prescription of two or three and more glucose-lowering drugs. Poor lipid control was associated only with Malay and Indian ethnicities. SPM prescription has increased over time, but the achievement of treatment targets, particularly for lipid control, has remained poor and unchanged. Statin use is not associated with lipid control. The accessibility and availability of alternative lipid-lowering drugs must be improved to enhance overall RF control, especially lipid control, in patients with DM and cardiovascular diseases.

Using status of secondary prevention medications in post-stroke dysphagia patients: time to raise awareness and develop special formulations

Post-stroke dysphagia (PSD) is an increasingly common complication of stroke. Despite its intuitively unfavorable impact on secondary prevention medication use, limited awareness is available regarding this issue. Herein, a cross-sectional survey was conducted to determine the current use, patient-perceived needs and preferences for secondary prevention medications among PSD patients. To emphasize the unique context related to dysphagia, we recruited Chinese stroke patients with a duration of less than 5 years. These patients were initially categorized into PSD respondents with and without dysphagia. Among the 3490 eligible respondents, 42.7% reported experiencing dysphagia after stroke. Those PSD respondents were more likely to consume multiple medications and suffer from anticoagulants-associated gastrointestinal bleeding as compared to non-PSD ones (p < 0.001). More crucially, 40.2% of them had frequent difficulty in swallowing pills, 37.1% routinely crushed solid oral dosage forms (SODFs), and 23.5% coughed frequently when taking SODFs. In consequence, 87.4% responded a need for PSD-specific formulations where safe swallowing, easy swallowing, and reduced medication frequency were preferred pharmaceutical factors. These findings demonstrate an unsatisfactory situation and definite needs for PSD patients in using secondary prevention medications. Awareness should be increased to develop PSD-specific formulations for safe and effective secondary prevention.

Patterns of 12-Month Post-Myocardial Infarction Medication Use According to Revascularisation Strategy: Analysis of 15,339 Admissions in Victoria, Australia

Clinical guidelines recommend secondary prevention medications following myocardial infarction (MI) regardless of revascularisation strategy. Studies suggest that there is variation in post-MI medication use following percutaneous coronary intervention (PCI) and coronary artery bypass grafts (CABG). We investigated initial dispensing and 12-month patterns of medication use according to revascularisation strategy following non-ST-elevation MI (NSTEMI). We included all public and private hospital admissions for NSTEMI for patients aged ≥30 years in Victoria, Australia, between July 2012 and June 2017. We investigated initial dispensing of P2Y12 inhibitors (P2Y12i), statins (total and high intensity), angiotensin-converting-enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB), and beta blockers within 60 days after discharge. Twelve-month post-MI medication use was estimated as the proportion of days covered (PDC) over a 12-month period from the date of hospital discharge. Analyses were performed using adjusted regression models, stratified by revascularisation strategy. There were 15,399 admissions for NSTEMI: 11,754 with PCI and 3,645 with CABG. Following adjustments, predicted probability of initial dispensing in the PCI and CABG groups, respectively, was 0.94 (95% confidence interval 0.93-0.95) vs 0.17 (0.13-0.21) for P2Y12i; 0.69 (0.66-0.71) vs 0.42 (0.37-0.48) for ACEi/ARB; 0.59 (0.57-0.62) vs 0.69 (0.64-0.74) for beta blockers; 0.89 (0.87-0.91) vs 0.89 (0.85-0.92) for statins; and 0.60 (0.57-0.62) vs 0.69 (0.63-0.73) for high intensity statins. The 12-month PDC in the PCI and CABG groups, respectively, was 0.82 (0.80-0.83) vs 0.12 (0.09-0.15) for P2Y12i; 0.62 (0.60-0.65) vs 0.43 (0.39-0.48) for ACEi/ARB; 0.53 (0.51-0.55) vs 0.632 (0.58-0.66) for beta blockers; 0.79 (0.78-0.81) vs 0.78 (0.74-0.81) for statins; and 0.49 (0.47-0.51) vs 0.55 (0.50-0.59) for high intensity statins. Post-discharge dispensing of secondary prevention medications differed with respect to revascularisation strategy from 2012 to 2017, despite clear evidence of benefit during this period. Interventions may be needed to address possible clinician and patient uncertainty about the benefits of secondary prevention medications, regardless of revascularisation strategy.

Determinants of adherence to post-stroke/transient ischemic attack secondary prevention medications: A cohort study.

Adherence to post-stroke secondary prevention medications mitigates recurrence risk. This study aimed to measure adherence to secondary prevention medications during 3 years post-ischemic stroke/transient ischemic attack, using prescription and dispensing data, and identify factors associated with suboptimal adherence. This multicenter, prospective, cohort study involved patients from the STROKE 69 cohort, which included all consecutive patients with suspected acute stroke admitted between November 2015 and December 2016 to any emergency department or stroke center in the Rhône area in France. Prescription data for antihypertensive agents, antidiabetic agents, lipid-lowering drugs, and antithrombotics were collected. Dispensing data were provided by the French regional reimbursement database. Adherence was calculated using the continuous medication acquisition index. Associations between suboptimal adherence and potential influencing factors across the World Health Organization's five dimensions were explored through univariate and multivariate analyses. From 1512 eligible patients, 365 were included. Optimal adherence to overall treatment (≥90%) was observed in 61%, 62%, and 65% of patients in the first, second, and third years, respectively. Education level (high school diploma or higher: OR = 3.24, 95% CI [1.49; 7.36]) and depression (Hospital Anxiety and Depression Scale-Depression scores 8-10: OR = 1.90, 95% CI [1.05; 3.44]) were significantly associated with suboptimal adherence. Overall adherence to secondary prevention medications was fairly good. Having an initial diagnosis of transient ischemic attack, a high level of education, or depression was associated with increased odds of suboptimal adherence, while having a history of heart rhythm disorder was associated with lower odds.

Cervicocerebral Atherosclerosis Burden Increases Long-Term Mortality in Patients With Ischemic Stroke or Transient Ischemic Attack.

The influence of burden of atherosclerosis in the brain supplying arteries on mortality in patients with acute ischemic stroke or transient ischemic attack is poorly known. We assessed whether total burden of atherosclerosis within cervicocerebral arteries is associated with long-term mortality. A total of 406 patients (median age, 71.8 years; 57.9% male) with acute ischemic stroke or transient ischemic attack were included and their cervicocerebral arteries imaged with computed tomography angiography. The presence of atherosclerotic findings was scored for 25 artery segments and points were summed as a Cervicocerebral Atherosclerosis Burden (CAB) score, analyzed as quartiles. Data on all-cause mortality came from Statistics Finland. After a median follow-up of 7.3 years, 147 (33.5%) patients had died. Compared with surviving patients, those who died had a higher median CAB score (5, interquartile range 2-10 versus 11, 7-16; P<0.001). Cumulative mortality increased from 8.9% (95% CI, 7.0-10.8) in the lowest to 61.4% (95% CI, 55.4-67.4) in the highest quartile of CAB score. Adjusted for demographics, cardiovascular risk factors, secondary preventive medication, and admission National Institute of Health Stroke Scale score, every CAB score point increased probability of death by 3%. Analyzed in quartiles, the highest CAB quartile was associated with a 2.5-fold likelihood of all-cause mortality. The main findings of our study were the increasing mortality with the total burden of computed tomography angiography-defined atherosclerosis in the brain supplying arteries after ischemic stroke or transient ischemic attack and that the CAB score-integrating this pathology-independently increased all-cause mortality.

Case management-based post-stroke care for patients with acute stroke and TIA (SOS-Care): a prospective cohort study

BackgroundThe high incidence of stroke recurrence necessitates effective post-stroke care. This study investigates the effectiveness of a case management-based post-stroke care program in patients with acute stroke and TIA.MethodsIn this prospective cohort study, patients with TIA, ischemic stroke or intracerebral hemorrhage were enrolled into a 12-month case management-based program (SOS-Care) along with conventional care. Control patients received only conventional care. The program included home and phone consultations by case managers, focusing on education, medical and social needs and guideline-based secondary prevention. The primary outcome was the composite of stroke recurrence and vascular death after 12 months. Secondary outcomes included vascular risk factor control at 12 months.ResultsFrom 11/2011 to 12/2020, 1109 patients (17.9% TIA, 77.5% ischemic stroke, 4.6% intracerebral hemorrhage) were enrolled. After 85 (7.7%) dropouts, 925 SOS-Care patients remained for comparative analysis with 99 controls. Baseline characteristics were similar, except for fewer males and less frequent history of dyslipidemia in post-stroke care. At 12 months, post-stroke care was associated with a reduction in the composite endpoint compared to controls (4.9 vs. 14.1%; HR 0.30, 95% CI 0.16–0.56, p < 0.001), with consistent results in ischemic stroke patients alone (HR 0.32, 95% CI 0.17–0.61, p < 0.001). Post-stroke care more frequently achieved treatment goals for hypertension, dyslipidemia, diabetes, BMI and adherence to secondary prevention medication (p < 0.05).ConclusionsCase management-based post-stroke care may effectively mitigate the risk of vascular events in unselected stroke patients. These findings could guide future randomized trials investigating the efficacy of case management-based models in post-stroke care.

10-Year Mortality After ST-Segment Elevation Myocardial Infarction Compared to the General Population

BackgroundST-segment elevation myocardial infarction (STEMI) is associated with high early mortality. However, it remains unclear if patients surviving the early phase have long-term excess mortality. ObjectivesThis study aims to assess excess mortality in STEMI patients treated with primary percutaneous coronary intervention (PCI) compared with an age- and- sex-matched general population at landmark periods 0 to 30 days, 31 to 90 days, and 91 days to 10 years. MethodsUsing the Western Denmark Heart Registry, we identified first-time PCI-treated patients who had primary PCI for STEMI from January 2003 to October 2018. Each patient was matched by age and sex to 5 individuals from the general population. ResultsWe included 18,818 patients with first-time STEMI and 94,090 individuals from the general population. Baseline comorbidity burden was similar in STEMI patients and matched individuals. Compared with the matched individuals, STEMI was associated with a 5.9% excess mortality from 0 to 30 days (6.0% vs 0.2%; HR: 36.44; 95% CI: 30.86-43.04). An excess mortality remained present from 31 to 90 days (0.9% vs 0.4%; HR: 2.43; 95% CI: 2.02-2.93). However, in 90-day STEMI survivors, the absolute excess mortality was only 2.1 percentage points at 10-year follow-up (26.5% vs 24.5%; HR: 1.04; 95% CI: 1.01-1.08). Use of secondary preventive medications such as statins, antiplatelet therapy, and beta-blockers was very high in STEMI patients throughout 10-year follow-up. ConclusionsIn primary PCI-treated STEMI patients with high use of guideline-recommended therapy, patients surviving the first 90 days had 10-year mortality that was only 2% higher than that of a matched general population.

Trends in the Use of Medications for Secondary Ischemic Stroke Prevention in Denmark, 2005-2021.

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. 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. 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. 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.

Severe mental illness: cardiovascular risk assessment and management.

Patients with severe mental illness (SMI) including schizophrenia and bipolar disorder die on average 15-20 years earlier than the general population often due to sudden death that, in most cases, is caused by cardiovascular disease. This state-of-the-art review aims to address the complex association between SMI and cardiovascular risk, explore disparities in cardiovascular care pathways, describe how to adequately predict cardiovascular outcomes, and propose targeted interventions to improve cardiovascular health in patients with SMI. These patients have an adverse cardiovascular risk factor profile due to an interplay between biological factors such as chronic inflammation, patient factors such as excessive smoking, and healthcare system factors such as stigma and discrimination. Several disparities in cardiovascular care pathways have been demonstrated in patients with SMI, resulting in a 47% lower likelihood of undergoing invasive coronary procedures and substantially lower rates of prescribed standard secondary prevention medications compared with the general population. Although early cardiovascular risk prediction is important, conventional risk prediction models do not accurately predict long-term cardiovascular outcomes as cardiovascular disease and mortality are only partly driven by traditional risk factors in this patient group. As such, SMI-specific risk prediction models and clinical tools such as the electrocardiogram and echocardiogram are necessary when assessing and managing cardiovascular risk associated with SMI. In conclusion, there is a necessity for differentiated cardiovascular care in patients with SMI. By addressing factors involved in the excess cardiovascular risk, reconsidering risk stratification approaches, and implementing multidisciplinary care models, clinicians can take steps towards improving cardiovascular health and long-term outcomes in patients with SMI.

The impact of frailty on initiation, continuation and discontinuation of secondary prevention medications following myocardial infarction

AimTo evaluate the association between frailty and initiating, continuing, or discontinuing secondary prevention medications following myocardial infarction (MI). MethodsWe conducted a cohort study using linked health data, including all adults aged ≥65 years who discharged from hospital following MI from January 2013 to April 2018 in Victoria, Australia (N = 29,771). The Hospital Frailty Risk Score (HFRS) was used to assess frailty. Logistic regression was used to investigate associations of frailty with initiation, continuation, and discontinuation of secondary prevention medications (P2Y12 inhibitor antiplatelets, beta-blockers, renin-angiotensin-aldosterone system (RAAS) inhibitors, and lipid-lowering therapies) in the 90 days from discharge post-MI, by HFRS, adjusted for age, sex, and Charlson Comorbidity Index. ResultsIncreasing frailty was associated with lower probability of initiating and continuing P2Y12 inhibitors, RAAS inhibitors, and lipid-lowering therapies, but not beta-blockers. At at an HFRS of 0, the predicted probabiliy of having all four medications initiated or continued was 0.59 (95 %CI 0.57–0.62) for STEMI and 0.35 (0.34–0.36) for non-STEMI, compared to 0.38 (0.33–0.42) and 0.16 (0.14–0.18) at an HFRS of 15. Increasing frailty was associated with higher probability of discontinuing these medications post-MI. The predicted probability of discontinuing at least one secondary prevention medication post-MI at an HFRS of 0 was 0.10 (0.08–0.11) for STEMI and 0.14 (0.13–0.15) for non-STEMI, compared to 0.27 (0.22–0.32) and 0.34 (0.32–0.36) at an HFRS of 15. ConclusionPeople with higher levels of frailty were managed more conservatively following MI than people with lower levels of frailty. Whether this conservative treatment is justified warrants further study.

Statin treatment after surgical aortic valve replacement for aortic stenosis is associated with better long-term outcome.

The aim of this study was to evaluate the association between statin use after surgical aortic valve replacement for aortic stenosis and long-term risk for major adverse cardiovascular events (MACEs) in a large population-based, nationwide cohort. All patients who underwent isolated surgical aortic valve replacement due to aortic stenosis in Sweden 2006-2020 and survived 6 months after discharge were included. Individual patient data from 5 nationwide registries were merged. Primary outcome is MACE (defined as all-cause mortality, myocardial infarction or stroke). Multivariable Cox regression model adjusted for age, sex, comorbidities, valve type, operation year and secondary prevention medications is used to evaluate the association between time-updated dispense of statins and long-term outcome in the entire study population and in subgroups based on age, sex and comorbidities. A total of 11894 patients were included. Statins were dispensed to 49.8% (5918/11894) of patients at baseline, and 51.0% (874/1713) after 10 years. At baseline, 3.6% of patients were dispensed low dose, 69.4% medium dose and 27.0% high-dose statins. After adjustments, ongoing statin treatment was associated with a reduced risk for MACE [adjusted hazard ratio 0.77 (95% confidence interval 0.71-0.83). P < 0.001], mainly driven by a reduction in all-cause mortality [adjusted hazard ratio, 0.70 (0.64-0.76)], P < 0.001. The results were consistent in all subgroups. The results suggest that statin therapy might be beneficial for patients undergoing surgical aortic valve replacement for aortic stenosis. Randomized controlled trials are warranted to establish causality between statin treatment and improved outcome.

Adherence to secondary stroke prevention medications in Singapore: a single center study

ObjectivesRecurrent strokes are associated with greater disability and mortality than first-time strokes. However, adherence to secondary stroke prevention medications has been reported to be suboptimal. We assessed medication adherence to antihypertensives, antiplatelets, and statins after acute ischemic stroke and identified factors associated with non-adherence behavior to each drug class. MethodsThis single center study is an extension of a larger prospective cohort study of ischemic stroke patients assessed at an outpatient post stroke clinic. Medication adherence behavior and medication knowledge was determined by direct questioning, and perceptions towards medications via the Beliefs about Medicines Questionnaire. Factors associated with non-adherence in each drug class were determined using logistic regression. ResultsRates of adherence differed between antihypertensives (77.9%), antiplatelets (80.3%), and statins (64.7%) (p < 0.001) amongst the 193 patients surveyed. Non-adherence to antihypertensives was associated with living alone, taking < 5 medications, and stronger beliefs that medications are harmful. For antiplatelets, non-diabetic patients and patients with stronger beliefs that medications are harmful were more likely to be non-adherent. Patients non-adherent to statins were more likely to have a longer time since ischemic event and have a transient ischemic attack as the index event. ConclusionsOverall, medication adherence behavior to secondary stroke prevention medications was poor, with statins the least adhered to. Factors associated with non-adherence to each drug class could guide the development of tailored interventions to improve adherence to secondary stroke prevention medications.

Investigation of vascular risk factor control and secondary prevention medication compliance in acute ischemic stroke.

This study aimed to investigate the management of vascular risk factors, with a specific focus on understanding the various factors affecting risk factor control through an in-depth analysis of clinical data and a longitudinal follow-up of patients who have experienced ischemic strokes. A total of 1,572 participants were included in the analysis. We assessed thresholds for blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), and glycated hemoglobin (HbA1c) levels to uncover the contextual conditions and factors affecting vascular risk factor control. Moreover, the study also scrutinized medication compliance at intervals of 3, 6, and 12 months post-onset. Logistic regression was used to adjust for confounding factors. At 3, 6, and 12 months, BP,LDL, hemoglobin control targets were achieved in 50.7, 51.8, and 50.6%; 51.5, 59.4, and 50.6%; 48.1, 44.0, and 48.4%,respectively. Notably, age was associated with the achievement of BP control (odds ratio [OR], 0.96; 95% confidence intervals [CI], 0.94-0.98; p < 0.0001). Ethnic minorities (OR, 4.23; 95% CI, 1.19-15.09; p = 0.02) and individuals with coronary heart disease (OR, 0.5; 95% CI, 0.3-1.0; p = 0.05) experienced decreased BP control ratios. A previous history of stroke (OR, 1.7; 95% CI, 1.0-2.8; p = 0.03) and unrestricted alcohol consumption (OR, 3.3; 95% CI, 1.0-11.1; p = 0.05) was significantly associated with the achievement of lipid control. Furthermore, lifestyle modifications were significantly correlated with the achievement of BP control (OR, 0.19; 95% CI, 0.12-0.30; p < 0.01), blood glucose control (OR, 0.03; 95% CI, 0.01-0.08; p < 0.01), and blood lipid control (OR, 0.26; 95% CI, 0.16-0.42; p < 0.01). The absence of regular physical activity was associated with lower rates of glycemic (OR, 0.14; 95% CI, 0.06-0.36; p < 0.01) and lipid controls (OR, 0.55; 95% CI, 0.33-0.90; p = 0.01). Over time, overall medication compliance declined. Within the cohort of patients under medication, the compliance rate concerning vascular risk factors remains unsatisfactory. Attention should be paid to compliance with secondary prevention medications and enhance the control of vascular risk factors, as compliance emerges as the key to effective prevention.
