Efficacy and Safety of Ticagrelor Monotherapy in Patients Undergoing Percutaneous Coronary Intervention: A Meta-Analysis

Dual antiplatelet therapy (DAPT) and subsequent P2Y12 inhibitor monotherapy, particularly ticagrelor, is an emerging treatment strategy in patients undergoing percutaneous coronary intervention (PCI). This meta-analysis was designed to investigate whether short-term DAPT followed by ticagrelor monotherapy is associated with a favorable outcome as compared with standard DAPT (1–3 months of DAPT was termed “short-term” DAPT, 6–12 months DAPT was termed “standard” DAPT). The primary outcome was the composite of major adverse cardiovascular events (MACE) comprising myocardial infarction, stroke, and cardiovascular death. Secondary outcomes included all-cause mortality and net adverse clinical events (NACE; myocardial infarction, stroke, all-cause death, stent thrombosis, and major bleeding). The primary safety outcome was major bleeding. Three studies comprising 26,143 patients were included. The risk of MACE was similar between the two treatment groups (risk ratio (RR) 0.86, 95% confidence interval (CI), 0.72–1.02, P = 0.08, I2 = 22%). Short-term DAPT followed by ticagrelor monotherapy resulted in a 20% relative risk reduction of all-cause mortality (RR 0.80, 95% CI, 0.65–0.98, P = 0.03, I2 = 0%) and an 18% relative risk reduction of NACE (RR 0.82, 95% CI, 0.71–0.94, P = 0.005, I2 = 33%) as compared with standard DAPT. Short-term DAPT followed by ticagrelor monotherapy significantly decreased the risk of major bleeding (RR 0.67, 95% CI, 0.49–0.92, P = 0.01, I2 = 65%). In patients with acute coronary syndrome, short-term DAPT followed by ticagrelor monotherapy resulted in an unchanged ischemic risk but a significantly lower bleeding risk compared with standard DAPT. Short-term DAPT followed by ticagrelor monotherapy compared with standard DAPT resulted in a favorable safety and efficacy profile. Direct comparisons of aspirin vs. ticagrelor monotherapy following PCI are needed

Call to action for acute myocardial infarction in women: International multi-disciplinary practical roadmap

\ua9 2024 The Author(s). Published by Oxford University Press on behalf of the European Society of Cardiology.Cardiovascular diseases are the leading cause of death among women, and the incidence among younger women has shown the greatest increase over the last decades, in particular for acute myocardial infarction (AMI). Moreover, the prognosis of women post-AMI is poor when compared with men of similar ages. Since the 1990s, an abundant literature has highlighted the existing differences between sexes with regard to presentation, burden, and impact of traditional risk factors and of risk factors pertaining predominantly to women, the perception of risk by women and men, and the pathophysiological causations, their treatment, and prognosis. These data that have been accumulated over recent years highlight several targets for improvement. The objective of this collaborative work is to define the actions required to reverse the growing incidence of AMI in women and improve the patient pathway and care, as well as the prognosis. We aim to provide practical toolkits for different health professionals involved in the care of women, so that each step, from cardiovascular risk assessment to symptom recognition, to the AMI pathway and rehabilitation, thus facilitating that from prevention to intervention of AMI, can be optimized

Why We Need Specialised Centres for Women’s Hearts: Changing the Face of Cardiovascular Care for Women

Although cardiovascular disease (CVD) is the leading cause of mortality in women globally, cardiovascular care for women remains suboptimal, with poorer outcomes than for men. During the past two decades, there has been an incremental increase in research and publications on CVD in women, addressing sex-specific risk factors, symptoms, pathophysiology, treatment, prevention and identification of inequities in care. Nonetheless, once women have manifested CVD, they continue to have increasingly worse outcomes than men. An approach to addressing these global disparities has been the worldwide establishment of specialised centres providing cardiovascular care for women. These women’s heart centres (WHCs) allow a comprehensive approach to the cardiovascular care of women across the lifespan. The purpose of this article is to define the need for and role of these specialised centres by outlining sex-specific gaps in CVD care, and to provide guidance on components within WHCs that may be considered when establishing such programmes. © 2021 Radcliffe Group Ltd.

Comparative post-mortem study of cavum septi pellucidi in alcoholics, schizophrenics and aggressive persons

The appearance of cavum septi pellucidi (CSP) has been already connected with developmental disorders or with serious psychiatric diseases (schizophrenia, maniac-depressive disorder; aggressiveness or similar). During our investigation of CSP, group of alcoholics seemed to be interesting for investigation and comparison with the groups of schizophrenics and people with violent behavior: We obtained CSP in 205 out of 670 fixed brains (429 male and 241 female) of persons aged from l4 to 89 (mean ~ SD: 53.28 ~16.57), 85 cava belonged to our group of interest. Prevalence of CSP in aforementioned groups was significantly higher than in the rest of examined population. Only in the group of 20 to 39 years of age all kinds of obtained pathologies were present. Alcoholics with CSP suffered from cardiovascular diseases and died accidentally and aggressive persons were the only drug addicts in our examined group and they had the shortest life span. 34 out of 4l schizophrenics had no data about prior diseases and disorders and they were the ones who committed suicide frequently. Intensive demyelinization of corpus callosum and transformation of potential space between laminae of septum pellucidum to the actual one could explain the CSP appearance among alcoholics. To our opinion, cavum septi pellucidi might be used as an additional marker of organic brain changes in long term alcohol abuse, as a consequence of demyelinization due to lipolytic effect of ethanol, and lower cerebral blood flow

Noninvasive assessment of myocardial bridging by coronary flow velocity reserve with transthoracic Doppler echocardiography: vasodilator vs. inotropic stimulation

© 2016 Elsevier Ireland Ltd Background To consider hemodynamic assessment of myocardial bridging (MB) adequate, it is believed that inotropic stimulation with dobutamine should be estimated because its dynamic nature depends on the degree of extravascular coronary compression. This study evaluated comparative assessment of hemodynamic relevance of MB using coronary flow velocity reserve (CFVR) measurements by transthoracic Doppler echocardiography (TTDE) with vasodilatative and inotropic challenges. Methods This prospective study included forty-four patients with angiographic evidence of isolated MB of the left anterior descending coronary artery (LAD) and systolic compression of ≥ 50% diameter stenosis. All patients were evaluated by exercise stress-echocardiography (ExSE) test for signs of myocardial ischemia, and CFVR of the distal segment of LAD during iv.infusion of adenosine (ADO:140 μg/kg/min) and iv.infusion of dobutamine (DOB:10-40 μg/kg/min), separately. Results Exercise-SE was positive for myocardial ischemia in 8/44 (18%) of patients. CFVR during ADO was significantly higher than CFVR during peak DOB (2.85 ± 0.68 vs. 2.44 ± 0.48, p = 0.002). CFVR during peak DOB was significantly lower in SE-positive group in comparison to SE-negative group (2.01 ± 0.16 vs. 2.54 ± 0.47, p < 0.001), but not for ADO (2.47 ± 0.51 vs. 2.89 ± 0.70, p = 0.168), respectively. Multivariable logistic analysis showed that CFVR peak DOB was the most significant predictor of functional significant MB (OR 0.011, 95%CI: 0.001–0.507, p = 0.021). Receiver-operating characteristic curves have shown that TTDE-CFVR obtained by high-dose of dobutamine infusion is better than those by adenosine regarding to functional status of MB (AUC 0.861, p = 0.004; AUC 0.674, p = 0.179, respectively). Conclusions Non-invasive CFVR measurement by TTDE during inotropic stimulation, in comparison to vasodilation, provides more reliable functional evaluation of MB
