RESUMEN
Higher blood pressure levels in patients with depression may be associated with lower adherence to antihypertensive medications (AHMs). Here, we use electronic health record (EHR) data from the Estonian Biobank (EstBB) to investigate the role of lifetime depression in AHM adherence and persistence. We also explore the relationship between antidepressant initiation and intraindividual change in AHM adherence among hypertension (HTN) patients with newly diagnosed depression. Diagnosis and pharmacy refill data were obtained from the National Health Insurance database. Adherence and persistence to AHMs were determined for hypertension (HTN) patients initiating treatment between 2009 and 2017 with a three-year follow-up period. Multivariable regression was used to explore the associations between depression and AHM adherence or persistence, adjusting for sociodemographic, genetic, and health-related factors. A linear mixed-effects model was used to estimate the effect of antidepressant treatment initiation on antihypertensive medication adherence, adjusting for age and sex. We identified 20,724 individuals with newly diagnosed HTN (6294 depression cases and 14,430 controls). Depression was associated with 6% lower probability of AHM adherence (OR = 0.943, 95%CI = 0.909-0.979) and 12% lower odds of AHM persistence (OR = 0.876, 95%CI = 0.821-0.936). Adjusting for sociodemographic, genetic, and health-related factors did not significantly influence these associations. AHM adherence increased 8% six months after initiating antidepressant therapy (N = 132; ß = 0.078; 95%CI = 0.025-0.131). Based on the EHR data on EstBB participants, depression is associated with lower AHM adherence and persistence. Additionally, antidepressant therapy may help improve AHM adherence in patients with depression.

Aims: Data on how differences in risk factors, treatments, and outcomes differ between sexes in European countries are scarce. We aimed to study sex-related differences regarding baseline characteristics, in-hospital managements, and mortality of ST-elevation myocardial infarction (STEMI) patients in different European countries. Methods and results: Patients over the age of 18 with STEMI who were treated in hospitals in 2014-17 and registered in one of the national myocardial infarction registers in Estonia (n = 5817), Hungary (n = 30 787), Norway (n = 33 054), and Sweden (n = 49 533) were included. Cardiovascular risk factors, hospital treatment, and recommendation of discharge medications were obtained from the infarction registries. The primary outcome was mortality, in-hospital, after 30 days and after 1 year. Logistic and cox regression models were used to study the associations of sex and outcomes in the respective countries. Women were older than men (70-78 and 62-68 years, respectively) and received coronary angiography, percutaneous coronary intervention, left ventricular ejection fraction assessment, and evidence-based drugs to a lesser extent than men, in all countries. The crude mortality in-hospital rates (10.9-15.9 and 6.5-8.9%, respectively) at 30 days (13.0-19.9 and 8.2-10.9%, respectively) and at 1 year (20.3-28.1 and 12.4-17.2%, respectively) after hospitalization were higher in women than in men. In all countries, the sex-specific differences in mortality were attenuated in the adjusted analysis for 1-year mortality. Conclusion: Despite improved awareness of the sex-specific inequalities on managing patients with acute myocardial infarction in Europe, country-level data from this study show that women still receive less guideline-recommended management.
RESUMEN
Recall-by-genotype (RbG) studies conducted with population-based biobank data remain urgently needed, and follow-up RbG studies, which add substance to this research approach, remain solitary. In such studies, potentially disease-related genotypes are identified and individuals with those genotypes are recalled for consultation to gather more detailed clinical phenotypic information and explain to them the meaning of their genetic findings. Familial hypercholesterolemia (FH) is among the most common autosomal-dominant single-gene disorders, with a global prevalence of 1 in 500 (Nordestgaard et al., Eur. Heart J., 2013, 34 (45), 3478-3490). Untreated FH leads to lifelong elevated LDL cholesterol levels, which can cause ischemic heart disease, with potentially fatal consequences at a relatively early age. In most cases, the pathogenesis of FH is based on a defect in one of three LDL receptor-related genes-APOB, LDLR, and PCSK9. We present our first long-term follow-up RbG study of FH, conducted within the Estonian Biobank (34 recalled participants from a pilot RbG study and 291 controls harboring the same APOB, LDLR, and PCSK9 variants that were included in the pilot study). The participants' electronic health record data (FH-related diagnoses, lipid-lowering treatment prescriptions) and pharmacogenomic risk of developing statin-induced myopathy were assessed. A survey was administered to recalled participants to discern the impact of the knowledge of their genetic findings on their lives 4-6 years later. Significant differences in FH diagnoses and lipid-lowering treatment prescriptions were found between the recalled participants and controls (34 and 291 participants respectively). Our study highlights the need for more consistent lipid-lowering treatment adherence checkups and encourage more follow-up RbG studies to be performed.
RESUMEN
Aims: The aim of this study was to evaluate the effect of the intervention by proactively sharing a patient's high polygenic risk score (PRS) for coronary artery disease (CAD). Outcomes included: (i) reduction in cardiovascular disease (CVD) risk factors over 12 months; (ii) difference in purchased prescriptions of lipid-lowering and anti-hypertensive drugs between intervention group and control group subjects; and (iii) opinion of the participating physicians and subjects on PRS usefulness. Methods and results: This randomized controlled trial was conducted among middle-aged subjects with a top 20% CAD PRS in a family medicine setting. Participants were selected from 26 953 Estonian Biobank cohort participants. Subjects were informed and counselled about their PRS score and CAD risk using the visual tool at baseline (Visit I), counselling session (Visit II), and on the final Visit III at 12 months. The primary endpoint was not significantly different. However, the intervention group participants had a significantly higher probability of initiating statin treatment compared with the controls. Their levels of LDL-cholesterol (LDL-C) were significantly decreased compared with baseline on Visit III and significantly lower than in the control group. The vast majority of participating family physicians believe that finding out about genetic risks will affect the subject's lifestyle and medication compliance. Conclusion: Most of our outcome measures were in favour of this intervention. Participants achieved larger changes in cholesterol and blood pressure values. The vast majority (98.4%) of family physicians are interested in continuing to use genetic risk assessment in practice.
RESUMEN
AIMS: To study baseline characteristics, in-hospital managements and mortality of non-ST-elevation myocardial infarction (NSTEMI) patients in different European countries. METHODS AND RESULTS: NSTEMI patients enrolled in the national myocardial infarction (MI) registries [EMIR; n = 5817 (Estonia), HUMIR; n = 30 787 (Hungary), NORMI; n = 33 054 (Norway), and SWEDEHEART; n = 49 533 (Sweden)] from 2014 to 2017 were included and presented as aggregated data. The median age at admission ranged from 70 to 75 years. Current smoking status was numerically higher in Norway (24%), Estonia (22%), and Hungary (19%), as compared to Sweden (17%). Patients in Hungary had a high rate of diabetes mellitus (37%) and hypertension (84%). The proportion of performed coronary angiographies (58% vs. 75%) and percutaneous coronary interventions (38% vs. 56%), differed most between Norway and Hungary. Prescription of dual antiplatelet therapy at hospital discharge ranged from 60% (Estonia) to 81% (Hungary). In-hospital death ranged from 3.5% (Sweden) to 9% (Estonia). The crude mortality rate at 1 month was 12% in Norway and 5% in Sweden (5%), whereas the 1-year mortality rates were similar (20-23%) in Hungary, Estonia, and Norway and 15% in Sweden. CONCLUSION: Cross-comparisons of four national European MI registries provide important data on differences in risk factors and treatment regiments that may explain some of the observed differences in death rates. A unified European continuous MI registry could be an option to better understand how implementation of guideline-recommended therapy can be used to reduce the burden of cardiovascular disease.

AIMS: Describe the characteristics, management and outcomes of hospitalized ST-segment elevation myocardial infarction (STEMI) patients according to national ongoing myocardial infarction registries in Estonia, Hungary, Norway, and Sweden. METHODS AND RESULTS: Country-level aggregated data was used to study baseline characteristics, use of in-hospital procedures, medications at discharge, in-hospital complications, 30-day and 1-year mortality for all patients admitted with STEMI during 2014-2017 using data from EMIR (Estonia; n = 4584), HUMIR (Hungary; n = 23 685), NORMI (Norway; n = 12 414, data for 2013-2016), and SWEDEHEART (Sweden; n = 23 342). Estonia and Hungary had a higher proportion of women, patients with hypertension, diabetes, and peripheral artery disease compared to Norway and Sweden. Rates of reperfusion varied from 75.7% in Estonia to 84.0% in Sweden. Rates of recommendation of discharge medications were generally high and similar. However, Estonia demonstrated the lowest rates of dual antiplatelet therapy (78.1%) and statins (86.5%). Norway had the lowest rates of beta-blockers (80.5%) and angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (61.5%). The 30-day mortality rates ranged between 9.9% and 13.4% remaining lowest in Sweden. One-year mortality rates ranged from 14.8% in Sweden and 16.0% in Norway to 20.6% in Hungary and 21.1% in Estonia. Age-adjusted lethality rates were highest for Hungary and lowest for Sweden. CONCLUSION: This inter-country comparison of data from four national ongoing European registries provides new insights into the risk factors, management and outcomes of patients with STEMI. There are several possible reasons for the findings, including coverage of the registries and variability of baseline-characteristics' definitions that need to be further explored.

BACKGROUND: We aim to investigate the predictive ability of PCE (Pooled Cohort Equations), QRISK2 and SCORE (Systematic COronary Risk Estimation) scoring systems for atherosclerotic cardiovascular disease (ASCVD) risk prediction in Estonia, a country with one of the highest ASCVD event rates in Europe. METHODS: Seven-year risk estimates were calculated in risk score-specific subsets of the Estonian Biobank cohort. Calibration was assessed by standardised incidence ratios (SIRs) and discrimination by Harrell's C-statistics. In addition, a head-to-head comparison of the scores was performed in the intersection of the three score-specific subcohorts. RESULTS: PCE, QRISK2 and SCORE risk estimates were calculated for 4356, 7191 and 3987 eligible individuals, respectively. During the 7-year follow-up, 220 hard ASCVD events (PCE outcome), 671 ASCVD events (QRISK2 outcome) and 94 ASCVD deaths (SCORE outcome) occurred among the score-specific subsets of the cohort. While PCE (SIR 1.03, 95% CI 0.90 to 1.18) and SCORE (SIR 0.99, 95% CI 0.81 to 1.21) were calibrated well for the cohort, QRISK2 underestimated the risk by 48% (SIR 0.52, 95% CI 0.48 to 0.56). In terms of discrimination, PCE (C-statistic 0.778) was inferior to QRISK2 (C-statistic 0.812) and SCORE (C-statistic 0.865). All three risk scores performed at similar level in the head-to-head comparison. CONCLUSION: Of three widely used ASCVD risk scores, PCE and SCORE performed at acceptable level, while QRISK2 underestimated ASCVD risk markedly. These results highlight the need for evaluating the accuracy of ASCVD risk scores prior to use in high-risk populations.

PURPOSE: Large-scale, population-based biobanks integrating health records and genomic profiles may provide a platform to identify individuals with disease-predisposing genetic variants. Here, we recall probands carrying familial hypercholesterolemia (FH)-associated variants, perform cascade screening of family members, and describe health outcomes affected by such a strategy. METHODS: The Estonian Biobank of Estonian Genome Center, University of Tartu, comprises 52,274 individuals. Among 4776 participants with exome or genome sequences, we identified 27 individuals who carried FH-associated variants in the LDLR, APOB, or PCSK9 genes. Cascade screening of 64 family members identified an additional 20 carriers of FH-associated variants. RESULTS: Via genetic counseling and clinical management of carriers, we were able to reclassify 51% of the study participants from having previously established nonspecific hypercholesterolemia to having FH and identify 32% who were completely unaware of harboring a high-risk disease-associated genetic variant. Imaging-based risk stratification targeted 86% of the variant carriers for statin treatment recommendations. CONCLUSION: Genotype-guided recall of probands and subsequent cascade screening for familial hypercholesterolemia is feasible within a population-based biobank and may facilitate more appropriate clinical management.

BACKGROUND: The purpose was to describe the treatment and outcomes of non-ST-elevation myocardial infarction (NSTEMI) in Estonia according to patients' estimated mortality risk by the Global Registry of Acute Coronary Events (GRACE) score and investigate if inequalities in treatment had an impact on prognosis. METHODS: We performed a linkage between Estonian Myocardial Infarction Registry, Population Registry and Estonian Health Insurance Fund. All NSTEMI patients 2012-2014 were stratified into low (<4%), intermediate (4-12%), or high (>12%) mortality risk according to GRACE. All-cause mortality and composite endpoint of death, recurrent myocardial infarction, stroke or unplanned revascularization were compared between optimally - defined as concomitant in-hospital use of medicines from recommended groups and coronary angiography - and suboptimally managed patients, using the Cox regression. RESULTS: Out of 3803 NSTEMI patients (median age 73â¯years, 44% women) 20% were classified into low, 35% into intermediate and 45% into high risk category. In these groups, respectively, 62%, 46% and 23% of patients received optimal in-hospital management. Over the mean follow-up of 2.4â¯years the association between suboptimal in-hospital management and outcomes was the following: in the low risk group mortality hazard ratio (HR) 1.6 (95% confidence interval 0.8-3.2), composite endpoint HR 1.2 (0.8-1.8); in the intermediate risk group mortality HR 2.4 (1.7-3.3), composite endpoint HR 1.8 (1.4-2.3); and in the high risk group mortality HR 2.2 (1.8-2.8), composite endpoint HR 1.6 (1.3-2.0). CONCLUSIONS: Higher risk NSTEMI patients received less guideline-recommended in-hospital management, which was associated with a worse prognosis.

BACKGROUND: The aim of the study was to explore trends in short- and long-term mortality after hospitalization for acute myocardial infarction (AMI) over the period 2001â2011 in Estonian secondary and tertiary care hospitals while adjusting for changes in baseline characteristics. METHODS: In this nationwide cross-sectional study random samples of patients hospitalized due to AMI in years 2001, 2007 and 2011 were identified and followed for 1 year. Trends in 30-day and 1-year all-cause mortality were analysed using Cox proportional hazards regression model. RESULTS: The final analysis included 423, 687 and 665 patients in years 2001, 2007 and 2011 respectively. During the study period, the prevalence of most comorbidities remained unchanged while the in-hospital and outpatient treatment improved significantly. For example, the proportion of tertiary care hospital AMI patients who underwent revascularization was almost three times higher in 2011 compared to 2001. The proportion of secondary care patients who were referred to a tertiary care centre for more advanced care increased from 5.8 to 40.1 % (p for trend <0.001). Meanwhile, the 1-year mortality rates decreased from 29.5 to 20.2 % (adjusted p = 0.004) in the tertiary and from 32.4 to 23.1 % (adjusted p = 0.006) in the secondary care. The decrease in the 30-day mortality rates was statistically significant only in the secondary care hospitals. CONCLUSIONS: The use of evidence-based treatments in Estonian AMI patients improved between 2001 and 2011. At the same time, we observed a significant reduction in the long-term mortality rates, both for patients primarily hospitalized into secondary as well as into tertiary care hospitals.
