Background: Studies that have reported lower risk for cardiovascular outcomes in users of Sodium-Glucose Cotransporter-2 Inhibitors (SGLT-2i) are limited by residual cofounding and lack of information on prior cardiovascular disease (CVD). This study compared risk of cardiovascular events in patients within routine care settings in Europe and Asia with type 2 diabetes (T2D) initiating empagliflozin compared to dipeptidyl peptidase-4 inhibitors (DPP-4i) stratified by pre-existing CVD and history of heart failure (HF)., Methods and Results: Adults initiating empagliflozin and DPP-4i in 2014-2018/19 from 11 countries in Europe and Asia were compared using propensity score matching and Cox proportional hazards regression to assess differences in rates of primary outcomes: hospitalisation for heart failure (HHF), myocardial infarction (MI), stroke; and secondary outcomes: cardiovascular mortality (CVM), coronary revascularisation procedure, composite outcome including HHF or CVM, and 3-point major adverse cardiovascular events (MACE: MI, stroke and CVM). Country-specific results were meta-analysed and pooled hazard ratios (HR) with 95% confidence intervals (CI) from random-effects models are presented. In total, 85,244 empagliflozin/DPP4i PS-matched patient pairs were included with overall mean follow-up of 0.7 years. Among those with pre-existing CVD, lower risk was observed for HHF (HR 0.74; 95% CI 0.64-0.86), CVM (HR 0.55; 95% CI 0.38-0.80), HHF or CVM (HR 0.57; 95% CI 0.48-0.67) and stroke (HR 0.79; 95% CI 0.67-0.94) in patients initiating empagliflozin vs DPP-4i. Similar patterns were observed among patients without pre-existing CVD and those with and without pre-existing HF., Conclusion: These results from diverse patient populations in routine care settings across Europe and Asia demonstrate that initiation of empagliflozin compared to DPP-4i results in favourable cardioprotective effects regardless of pre-existing CVD or HF status., (© 2023.

Purpose: The most important management strategy in atrial fibrillation (AF) patients is preventing stroke with oral anticoagulants. Warfarin is still used as a first-line anticoagulant, although non-vitamin K antagonist oral anticoagulants are currently recommended to manage AF. Using a large, unselected national sample of AF patients, we evaluated the relationships between quality of warfarin therapy and the risks of thromboembolism, bleeding complications, and mortality., Methods: The nationwide FinWAF study included 54 568 AF patients taking warfarin. Time in the therapeutic range (TTR) was calculated on a continuous basis using the Rosendaal method and international normalized ratio values over the previous 60 days. Adjusted Cox proportional hazard models were prepared for different TTR levels and major clinical end points., Results: The mean age of patients was 73.1 years (standard deviation 10.8), and 47% were female. The mean follow-up time was 3.2 ± 1.6 years (median 3.4). In the TTR groups of ≤40%, 60-70%, 70-80%, and >80%, the annual risk of stroke was 9.3%, 4.7%, 4.6%, and 3.1%; bleeding events 7.5%, 4.5%, 4.3%, and 2.6%; and overall mortality 20.9%, 8.5%, 6.4%, and 3.1%, respectively. All differences among the TTR groups were highly significant (p < 0.001)., Conclusions: The quality of warfarin treatment was strongly associated with the risk of stroke and the prognosis of AF patients. Patient outcomes continued to improve with increasing TTR values up to a TTR ≥80%; therefore, the target for the TTR should exceed 80% instead of the traditional range of at least 60-70%.

Study Question: Does the use of post-menopausal vaginal estradiol (VE) affect the mortality risk for coronary heart disease (CHD) and stroke., Summary Answer: The use of VE reduces the risk for cardiovascular mortality., What Is Known Already: A growing number of women use VE for post-menopausal genitourinary symptoms. Although this therapy is intended to have only local effects, estrogen is absorbed into the blood circulation and thus VE use may also have systemic effects., Study Design, Size, Duration: We studied a nationwide cohort in Finland 1994-2009 during which post-menopausal women (n = 195 756) initiated the use of VE (age [mean ± SD] 65.7 ± 10.9 years). Follow-up data gathered 1.4 million women-years and we assessed the mortality risk due to CHD (n= 9656) or stroke (n = 4294)., Participants/materials, Setting, Methods: The mortality risk in VE users was compared with that in the age-matched background population (standardized mortality ratio; [SMR]; 95% confidence interval) and related to various durations of exposure to VE (1 to ≤3, >3 to ≤5, >5 to ≤10 and >10 years)., Main Results and the Role of Chance: The use of VE was accompanied by decreases in the risk for CHD and stroke death. The risk reduction for CHD death was highest for >3 to ≤5 years exposure (SMR 0.64; 0.57-0.70) and for stroke for >5 to ≤10 years exposure (SMR 0.64; 0.57-0.72). The risk reductions for both CHD and stroke mortality were detected in all age groups with the highest risk reduction being in women aged 50-59 years (SMR 0.43; 0.19-0.88 and SMR 0.21; 0.06-0.58, respectively)., Limitations, Reasons for Caution: Our series lack a placebo arm and thus, may harbor a healthy woman bias. Moreover, data on clinical variables such as weight, smoking, blood pressure and family background were unobtainable for this study. Women using both VE and systemic hormone therapy (HT) were included in the comparator background population. This should not cause any significant error because the proportion of women using VE or other HT was modest (<10% in age-matched population) and because the use of systemic HT also reduces death risks in the same population. Our data cannot be directly applied for local regimens containing conjugated equine estrogens, because they are absorbed differently and may show effects that differ from those of estradiol., Wider Implications of the Findings: In 1000 women using VE for up to 10 years, a maximum of 24 fewer CHD deaths and 18 fewer stroke deaths is likely to occur., Study Funding/competing Interests: This work was supported by unrestricted grants from the Päivikki and Sakari Sohlberg Foundation, the Emil Aaltonen Foundation, the Finnish Medical Foundation, Finska Läkaresällskapet, the Orion Farmos Research Foundation, the Paavo Nurmi Foundation and a special governmental grant for health sciences research.

Objective: Data on the health benefits and risks of postmenopausal hormone therapy (HT) are derived mainly from the use of conjugated equine estrogens. Estradiol-based regimens may have a different risk-benefit profile. We evaluated the risk of death caused by coronary heart disease (CHD), stroke, or any disease among users of estradiol-based HT regimens in a nationwide study in Finland., Methods: A total of 489,105 women who used HT from 1994 to 2009 (3.3 million HT exposure years), as indicated in the nationwide reimbursement register and the national Cause of Death Register, were followed. A total of 28,734 HT users died during follow-up; among the deaths, 3,843 were caused by CHD and 2,464 were caused by stroke. Mortality risk in HT users with varying duration of exposure (≤1 y, >1 to 3 y, >3 to 5 y, >5 to 10 y, or >10 y) was compared with that in an age-matched background population., Results: Risk of CHD death was significantly reduced by 18% to 54% in HT users and was positively related to HT exposure time. Risk of stroke death was also reduced by 18% to 39%, but this reduction was not clearly related to HT exposure time. Risk of all-cause mortality was reduced in HT users by 12% to 38%, almost in linear relationship with duration of exposure. All these risk reductions were comparable in women initiating HT before age 60 years and women initiating HT at age 60 years or older., Conclusions: In absolute terms, the risk reductions mean 19 fewer CHD deaths and 7 fewer stroke deaths per 1,000 women using any HT for at least 10 years.

Objective: The Women's Health Initiative (WHI) study clarified the indications and contraindications for postmenopausal hormone therapy (HT). We studied the impact of the WHI results on the risk of fatal stroke in HT users in Finland., Study Design: Retrospective analysis setting: Nationwide registers on postmenopausal HT use and causes of death between 1995 and 2009., Population: Women ≥40 years (n=290,272) using systemic estradiol-based postmenopausal HT., Methods: Follow-up started from the first HT purchase during the pre-WHI era (1995-2001) and post-WHI era (2002-2009)., Main Outcome Measures: Stroke deaths in HT users were compared with that in the age-matched background population and expressed as standardized mortality ratio (SMR) with 95% confidence intervals., Results: Overall, 311 HT users died due to stroke. The exposure to HT ≤1 year was associated with a similarly reduced 22% (0.67-0.91) risk of stroke death in the pre-WHI era and in the post-WHI era 27% (0.55-0.94). The risk reductions for HT exposure of 1-8 years in the pre-WHI era (47%, 0.42-0.65) did not differ from that in the post-WHI era (32%, 0.48-0.94). The discontinuation of HT was accompanied by a significant 33% (1.02-1.72) increase in stroke death risk in the pre-WHI era and a non-significant 32% (0.84-1.99) increase in the post-WHI era within the first post-treatment year, but no longer after 1-8 years., Conclusions: The change in prescribing policy after the WHI study did not affect the risk of fatal stroke in Finnish HT users., (Copyright © 2015 Elsevier Ireland Ltd.
