Several de-escalation strategies of antiplatelet treatment aiming to enhance safety of DAPT without depriving it of its efficacy have been evaluated so far. We hypothesized that reduction of the ticagrelor maintenance dose 1 month after ACS and its continuation until 12 months after ACS may improve adherence to antiplatelet treatment due to better tolerability compared with the standard dose of ticagrelor. Moreover, improved safety of treatment and preserved anti-ischemic benefit may also be expected with additional acetylsalicylic acid (ASA) withdrawal. To evaluate these hypotheses, we designed the Evaluating Safety and Efficacy of Two Ticagrelor-based De-escalation Antiplatelet Strategies in Acute Coronary Syndrome — a randomized clinical trial (ELECTRA-SIRIO 2), to assess the influence of ticagrelor dose reduction with or without continuation of ASA versus DAPT with standard dose ticagrelor in reducing clinically relevant bleeding and main-taining anti-ischemic efficacy in ACS patients. The study was designed as a phase III, randomized, multicenter, double-blind, investigator-initiated clinical study with a 12-month follow-up.Peer reviewedFinal Published versio

Prolonged antithrombotic therapy in patients after acute coronary syndrome: A critical appraisal of current European Society of Cardiology guidelines

The increased risk of non-cardiovascular death in patients receiving clopidogrel or prasugrel in comparison with the placebo group in the Dual Antiplatelet Therapy (DAPT) trial in contrast to the decreased risk of cardiovascular death and all-cause death seen in patients treated with low-dose ticagrelor in the EU label population of the PEGASUS-TIMI 54 trial, resulted in inclusion in the 2020 ESC NSTE-ACS guidelines the recommendation for use of clopidogrel or prasugrel only if the patient is not eligible for treatment with ticagrelor.The prevalence of the primary outcome composed of cardiovascular death, stroke, or myocardial infarction was lower in the low-dose rivaroxaban and acetylsalicylic acid (ASA) group than in the ASA-alone group in the COMPASS trial. Moreover, all-cause mortality and cardiovascular mortality rates were lower in the rivaroxaban-plus-ASA group.Comparison of the PEGASUS-TIMI 54 and COMPASS trial patient characteristics clearly shows that each of these treatment strategies should be addressed at different groups of patients. A greater benefit in post-acute coronary syndrome (ACS) patients with a high risk of ischemic events and without high bleeding risk may be expected with ASA and ticagrelor 60 mg b.i.d. when the therapy is continued without interruption or with short interruption only after ACS. On the other hand, ASA and rivaroxaban 2.5 mg b.i.d. seems to be a better option when indications for dual antithrombotic therapy (DATT) appear after a longer time from ACS (more than 2 years) and/or from cessation of DAPT (more than 1 year) and in patients with multiple vascular bed atherosclerosis. Thus, both options of DATTs complement each other rather than compete, as can be presumed from the recommendations. However, a direct comparison between these strategies should be tested in future clinical trials

National Trends in Statin Use in Lithuania from 2010 to 2021

Objective: In Lithuania, no comprehensive national research on statin utilization and trends has yet been undertaken. Nonetheless, this knowledge is critical for the healthcare system to identify key areas for development. We aimed to analyze trends in statin utilization in Lithuania from the past 12 years considering changes in reimbursement policies and the publication of updated international CVD prevention guidelines. Methods: We performed a retrospective, descriptive study of statin utilization in Lithuania from 2010 to 2021. The data were obtained from PharmaZOOM LT, an independent software supplier with nationwide coverage on pharmaceutical market data. The data coverage was 95%. We used anatomical therapeutic chemical (ATC) classification for data extraction and calculated defined daily doses (DDDs) according to the ATC/DDD Toolkit of World Health Organization according to statin dose in a pill. Results: Statin use increased overall from 8.28 DDD/TID in 2010 to 96.06 DDD/TID in 2021. The annual growth rate in sales of statin DDD/TID was 22.28%. The increase was mostly due to the increase in moderate- and high-intensity statins. The increases coincided with changes in reimbursement policy or the publication of international guidelines. Polypill use in Lithuania began steadily increasing after 2016 and reached 19.37% of the total DDD/TID of statins in 2021. Conclusions: The use of statins has increased dramatically in Lithuania over the last decade. Changes in statin reimbursement regulations in the country, as well as worldwide cardiovascular preventive recommendations aiming at lower LDL-C objectives, fueled the progress

Cocaine-induced myocardial injury

We report a case of 37-year-old male, who was admitted to the Vilnius University hospital Santaros Klinikos emergency department suffering from acute chest pain. ECG and elevated troponin level confirmed ST-elevation myocardial infarction, although coronary angiogram had not shown hemodynamically significant changes in coronary arteries. Patient admitted after using cocaine a day ago. To conclude, myocardial infarction is rare, but serious consequence of cocaine use. Clinicians should consider interrogating all young patients presented to the emergency department with acute chest pain for cocaine use

Vitamin D, cardiovascular and bone health in postmenopausal women with metabolic syndrome

Background. The evidence highlights the importance of improving vitamin D levels in the general population for the prevention of adverse long-term health risks, including cardiovascular events, metabolic syndrome, cancer, anxiety and depression, and overall mortality, although controversies in the research are common. Objectives. The purpose of this study was to investigate the relationship between vitamin D and vascular and bone health among postmenopausal metabolic women, controlling for traditional cardiovascular factors, and thus seeking to explore their plausible relation. The secondary aim was to look specifically for the relation between artery stiffness and bone health. Material and methods. This is a cross-sectional study designed to evaluate the relation between vitamin D level and vascular and bone health among women with metabolic syndrome. Two hundred and ten women visiting a cardiologist were recruited consecutively into the study. The study variables included clinical examination, laboratory findings, measurements of vascular stiffness, and bone turnover markers. Results. We found 126 (60%) metabolic women with a vitamin D deficiency (50 nmol/L) among the study group. We discovered no statistically significant correlation between vitamin D and vascular stiffness. Vitamin D was not associated neither with femoral neck bone mineral density (BMD) and T score, nor with lumbar spine BMD and T score. Nevertheless, there was an indirect weak correlation between vascular stiffness, in particular the augmentation index (AIx), and all bone health markers, including BMD and T score in both the femur head and lumbar spine. Conclusions. We showed a high proportion of postmenopausal metabolic women with a vitamin D deficiency, but there was no relation between vitamin D and vascular health or vitamin D and bone health. Nevertheless, the relation between vascular health and bone health exists, although the role of vitamin D in this link has not yet been established
