Underrepresentation of women in implantable cardioverter defibrillator trials

There are sex differences in the epidemiology and presentation of ventricular arrhythmias. Sudden cardiac death (SCD) is less common in women than in men. Women have been under-represented in implantable cardioverter defibrillator (ICD) trials evaluating the benefit of ICD therapy for primary and secondary prevention of SCD. Following ICD implantation, women are less likely to experience appropriate ICD therapy for ventricular arrhythmias, consistent with epidemiological findings of a lower rate of SCD in women. Sex differences in ICD implantation rates have also been noted for primary and secondary prevention of SCD in registries and large observational cohort studies. Reasons for these differences are unclear. Age and comorbidities at the time of presentation may be partially responsible, although sex bias, patient preference, or contribution of social determinants of health cannot be excluded. There are many unanswered questions regarding reasons for sex differences in ICD usage and under-representation of women in clinical device trials. Additional investigation is needed to better understand these differences to improve outcome of all patients who are at risk for sudden cardiac arrest.

Abstract TP204: Discharge Statin Practices For Young Stroke Patients In A Stroke Clinical Network

Background: Despite the association of statin use and lowered recurrent stroke and mortality, some studies suggest young stroke patients do not receive the same intense targeted treatment medical therapies for secondary stroke prevention as older patients. Our specific objective was to determine if there were differences in statin medication discharge practices provided to young ischemic stroke patients within a Stroke Clinical Network. The Stroke Clinical Network consists of nine stroke centers located in rural, suburban and urban geographical regions. Methods: The GWTG registry was queried (FY 2017-2021) to identify ischemic stroke patients to determine statin discharge practices using the following criteria: sex, race, age groups ≥18-39 and ≥40-49, LDL levels < 100, 101-129 and > 130, diabetes, HTN, and smoking status. Chi squared tests of proportions were used to evaluate significant relationships between subgroups. Results: Among 1,294 young ischemic stroke patients: 53% (682/1294) were Black and 38% (493/1294) White; mean age 40.9 years (SD +/-7.21years). Men, blacks, patients older than 40 and diabetics were more likely to be discharged on a statin. There was a direct correlation between sex, race, age, LDL level and diabetes with statin discharge practices. There was no difference in statin discharge practices between smokers and nonsmokers. Conclusions: Opportunities to improve compliance with obtaining LDL levels upon admission and prescribing statins at discharge exist. Increasing statin administration in the young stroke patient population reflects best practice and will decrease mortality and morbidity.

Global assessment improves risk stratification for major adverse cardiac events across a wide range of triglyceride levels: Insights from the KP REACH study

ObjectivePatients with risk factors for or established atherosclerotic cardiovascular disease (ASCVD) remain at high risk for subsequent ischemic events despite statin therapy. Triglyceride (TG) levels may contribute to residual ASCVD risk, and the performance of global risk assessment calculators across a broad range of TG levels is unknown. MethodsWe performed a retrospective cohort study of Kaiser Permanente Northern California members aged ≥45 years with ≥1 ASCVD risk factor (primary prevention cohort) or established ASCVD (secondary prevention cohort) between 2010 and 2017 who were receiving statin therapy and had a low-density lipoprotein cholesterol between 41–100 mg/dL. Global ASCVD risk assessment was performed using both the Kaiser Permanente ASCVD Risk Estimator (KPARE) and the ACC/AHA ASCVD Pooled Cohort Equation (PCE). Outcomes included major adverse cardiovascular events (MACE) defined as myocardial infarction, stroke, or peripheral artery disease, and expanded MACE (MACE + coronary revascularization + hospitalization for unstable angina). ResultsAmong 373,389 patients in the primary prevention cohort, median TG was 122 mg/dL (IQR 88–172 mg/dL) and there were 0.2 MACE events and 0.3 expanded MACE events per 100-person years. Among 97,832 patients in the secondary prevention cohort, median TG level was 116 mg/dL (IQR 84–164 mg/dL) and there were 9.6 MACE events and 22.0 expanded MACE events per 100-person years. KPARE and the ACC/AHA PCE stratified patients for MACE and expanded MACE over the entire range of TGs. ConclusionIn a cohort receiving statin therapy for primary or secondary prevention, we found global assessment further improves risk stratification for initial and/or recurrent ASCVD events irrespective of baseline TG level.

Antiplatelet Use in Ischemic Stroke.

Objective:A literature review of antiplatelet agents for primary and secondary stroke prevention, including mechanism of action, cost, and reasons for lack of benefit.Data sources:Articles were gathered from MEDLINE, Cochrane Reviews, and PubMed databases (1980-2021). s from scientific meetings were considered. Search terms included ischemic stroke, aspirin, clopidogrel, dipyridamole, ticagrelor, cilostazol, prasugrel, glycoprotein IIb/IIIa inhibitors.Study selection and data extraction:English-language original and review articles were evaluated. Guidelines from multiple countries were reviewed. Articles were evaluated independently by 2 authors.Data synthesis:An abundance of evidence supports aspirin and clopidogrel use for secondary stroke prevention. In the acute phase (first 21 days postinitial stroke), these medications have higher efficacy for preventing further stroke when combined, but long-term combination therapy is associated with higher hemorrhage rates. Antiplatelet treatment failure is influenced by poor adherence and genetic polymorphisms. Antiplatelet agents such as cilostazol may provide extra benefit over clopidogrel and aspirin, in certain racial groups, but further research in more diverse ethnic populations is needed.Relevance to patient care and clinical practice:This review presents the data available on the use of different antiplatelet agents poststroke. Dual therapy, recurrence after initiation of secondary preventative therapy, and areas for future research are discussed.Conclusions:Although good evidence exists for the use of certain antiplatelet agents postischemic stroke, there are considerable opportunities for future research to investigate personalized therapies. These include screening patients for platelet polymorphisms that confer antiplatelet resistance and for randomized trials including more racially diverse populations.

Beyond Lipid-Lowering: Effects of Statins on Cardiovascular and Cerebrovascular Diseases and Cancer.

The 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, also known as statins, are administered as first-line therapy for hypercholesterolemia, both as primary and secondary prevention. Besides the lipid-lowering effect, statins have been suggested to inhibit the development of cardiovascular disease through anti-inflammatory, antioxidant, vascular endothelial function-improving, plaque-stabilizing, and platelet aggregation-inhibiting effects. The preventive effect of statins on atherothrombotic stroke has been well established, but statins can influence other cerebrovascular diseases. This suggests that statins have many neuroprotective effects in addition to lowering cholesterol. Furthermore, research suggests that statins cause pro-apoptotic, growth-inhibitory, and pro-differentiation effects in various malignancies. Preclinical and clinical evidence suggests that statins inhibit tumor growth and induce apoptosis in specific cancer cell types. The pleiotropic effects of statins on cardiovascular and cerebrovascular diseases have been well established; however, the effects of statins on cancer patients have not been fully elucidated and are still controversial. This review discusses the recent evidence on the effects of statins on cardiovascular and cerebrovascular diseases and cancer. Additionally, this study describes the pharmacological action of statins, focusing on the aspect of ‘beyond lipid-lowering’.

Colchicine for Secondary Prevention of Coronary Artery Disease: A Meta-Analysis of Randomised Controlled Trials

Colchicine has become prominent as an anti-inflammatory therapy for secondary cardiovascular prevention in patients with coronary artery disease (CAD). This meta-analysis was performed to evaluate the efficacy and safety of colchicine in patients with CAD. Randomised controlled trials (RCTs) that compare major adverse cardiovascular events (MACEs) between patients with CAD randomised to colchicine versus placebo (or no colchicine) were included. Random effect risk ratios (RRs) were calculated for clinical outcomes. A total of 12,071 patients in seven RCTs were included in the meta-analysis. Compared with placebo or no colchicine, colchicine was associated with a significantly lower incidence of MACEs (RR 0.64, 95% CI 0.51-0.80, p<0.01). The reduction in MACEs in the colchicine group was driven by statistically significant reductions in the incidence of myocardial ischaemia (RR 0.74, 95% CI 0.58-0.95, p=0.02), coronary revascularisation (RR 0.61, 95% CI 0.42-0.89, p=0.01), and stroke (RR 0.48, 95% CI 0.28-0.83, p=0.01). However, there was no statistically significant difference for cardiovascular death (RR 0.82, 95% CI 0.55-1.22, p=0.33). All-cause and non-cardiovascular mortality, gastrointestinal events, infection, and cancer were not significantly different between the colchicine and control groups. Colchicine is a reasonably efficacious and safe drug that could be successfully utilised for the secondary prevention of CAD.

Cost-Effectiveness of Lipid-Lowering Therapies for Cardiovascular Prevention in Germany

PurposeNovel pharmaceutical treatments reducing cardiovascular events in dyslipidaemia patients must demonstrate clinical efficacy and cost-effectiveness to promote long-term adoption by patients, physicians, and insurers.ObjectiveTo assess the cost-effectiveness of statin monotherapy compared to additive lipid-lowering therapies for primary and secondary cardiovascular prevention from the perspective of Germany’s healthcare system.MethodsTransition probabilities and hazard ratios were derived from cardiovascular outcome trials for statin combinations with icosapent ethyl (REDUCE-IT), evolocumab (FOURIER), alirocumab (ODYSSEY), ezetimibe (IMPROVE-IT), and fibrate (ACCORD). Costs and utilities were retrieved from previous literature. The incidence of major adverse cardiovascular events was simulated with a Markov cohort model. The main outcomes were the incremental cost-effectiveness ratios (ICER) per quality adjusted life year (QALY) gained.ResultsFor primary prevention, the addition of icosapent ethyl to statin generated 0.81 QALY and €14,732 costs (ICER: 18,133), whereas fibrates yielded 0.63 QALY and € − 10,516 costs (ICER: − 16,632). For secondary prevention, the addition of ezetimibe to statin provided 0.61 QALY at savings of € − 5,796 (ICER: − 9,555) and icosapent ethyl yielded 0.99 QALY and €14,333 costs (ICER: 14,485). PCSK9 inhibitors offered 0.55 and 0.87 QALY at costs of €62,722 and €87,002 for evolocumab (ICER: 114,639) and alirocumab (ICER: 100,532), respectively. A 95% probability of cost-effectiveness was surpassed at €20,000 for icosapent ethyl (primary and secondary prevention), €119,000 for alirocumab, and €149,000 for evolocumab.ConclusionsFor primary cardiovascular prevention, a combination therapy of icosapent ethyl plus statin is a cost-effective use of resources compared to statin monotherapy. For secondary prevention, icosapent ethyl, ezetimibe, evolocumab, and alirocumab increase patient benefit at different economic costs.

Cancer and stroke: commonly encountered by clinicians, but little evidence to guide clinical approach.

The association between stroke and cancer is well-established. Because of an aging population and longer survival rates, the frequency of synchronous stroke and cancer will become even more common. Different pathophysiologic mechanisms have been proposed how cancer or cancer treatment directly or via coagulation disturbances can mediate stroke. Increased serum levels of D-dimer, fibrin degradation products, and CRP are more often seen in stroke with concomitant cancer, and the clot retrieved during thrombectomy has a more fibrin- and platelet-rich constitution compared with that of atherosclerotic etiology. Multiple infarctions are more common in patients with active cancer compared with those without a cancer diagnosis. New MRI techniques may help in detecting typical patterns seen in the presence of a concomitant cancer. In ischemic stroke patients, a newly published cancer probability score can help clinicians in their decision-making when to suspect an underlying malignancy in a stroke patient and to start cancer-screening studies. Treating stroke patients with synchronous cancer can be a delicate matter. Limited evidence suggests that administration of intravenous thrombolysis appears safe in non-axial intracranial and non-metastatic cancer patients. Endovascular thrombectomy is probably rather safe in these patients, but probably futile in most patients placed on palliative care due to their advanced disease. In this topical review, we discuss the epidemiology, pathophysiology, and prognosis of ischemic and hemorrhagic strokes as well as cerebral venous thrombosis and concomitant cancer. We further summarize the current evidence on acute management and secondary preventive therapy.

Renin-Angiotensin-Aldosterone System Inhibitors, Statins, and Beta-Blockers in Diabetic Patients With Critical Limb Ischemia and Foot Lesions.

Medical therapy for secondary prevention is known to be under-used in patients with peripheral artery disease (PAD). Few data are available on the subgroup with critical limb ischemia (CLI). Prescription of cardiovascular preventive therapies was recorded at discharge in a large, prospective cohort of patients admitted for treatment of CLI and foot lesions, stratified for coronary artery disease (CAD) diagnosis. All patients were followed up for at least 1 year. The primary endpoint was major adverse cardiovascular events (MACE). 618 patients were observed for a median follow-up of 981 days. Renin-angiotensin-aldosterone system (RAAS) inhibitors, statins, beta-blockers, and antithrombotic drugs were prescribed in 52%, 80%, 51%, and 99% of patients, respectively. However, only 43% of patients received optimal medical therapy (OMT), defined as the combination of RAAS inhibitor plus statin plus at least one antithrombotic drug. It was observed that the prescription of OMT was not affected by the presence of a CAD diagnosis. On the other hand, it was noticed that the renal function affected the prescription of OMT. OMT was independently associated with MACE (HR 0.688, 95%CI 0.475-0.995, P = .047) and, after propensity matching, also with all-cause mortality (HR 0.626, 95%CI 0.409-0.958, P = .031). Beta-blockers prescription was not associated with any outcome. In conclusion, patients with critical limb ischemia are under-treated with cardiovascular preventive therapies, irrespective of a CAD diagnosis. This has consequences on their prognosis.

Dual anti-platelet therapy for secondary prevention in intracranial atherosclerotic disease: a network meta-analysis

Background:Intracranial arterial stenosis (ICAS) is a non-marginal cause of stroke/transient ischemic attacks (TIAs) and is associated with high stroke recurrence rate. Some studies have investigated the best secondary prevention ranging from antithrombotic therapy to endovascular treatment (ET). However, no direct comparison between all the possible treatments is currently available especially between single and dual anti-platelet therapies (SAPT and DAPT).Aim:To establish whether DAPT is more effective than SAPT in preventing the recurrence of ICAS-related stroke, by means of a network meta-analysis (NMA).Design:Systematic review and NMA in accordance to PRISMA guidelines.Data sources and methods:We performed a systematic review of trials investigating secondary prevention (SAPT or DAPT, anticoagulant treatment or ET) in patients with symptomatic ICAS available in MEDLINE, Scopus and Web of Science from January 1989 to May 2021. We defined our primary efficacy outcome as the recurrence of ischemic stroke/TIA. We analysed the extracted data with Bayesian NMA approach.Results:We identified 815 studies and included 5 trials in the NMA. Sequence generation was adequate in all the selected studies while the allocation concealment method was described in one study. All the included studies reported the pre-specified primary outcomes, and outcome assessment was blinded in all the studies. We used the fixed-effect approach as the heterogeneity was not significant (p > 0.1) according to the Cochran’s Q statistic. DAPT was superior to SAPT and DAPT + ET in preventing stroke/TIA recurrence [respectively, odds ratio (OR), 0.59; confidence interval (CI), 0.39–0.9; and OR, 0.49, CI, 0.26–0.88], while no difference was found between DAPT and oral anticoagulant therapy (OAC). DAPT was safer than OAC (OR, 0.48; CI, 0.26–0.89) and DAPT + ET (OR, 0.50; CI, 0.35–0.71), while no difference was found between DAPT and SAPT.Conclusion:DAPT is more effective than SAPT for secondary stroke prevention in patients with symptomatic ICAS, without increasing the risk of haemorrhage.Registration:Prospero/CRD42019140033.

Influence of Physical Rehabilitation on the Restoration of Psychoemotional and Cognitive Impairment in Patients Suffered Cerebral Ischemic Stroke

Aim: To investigate the influence of physical rehabilitation on psycho-emotional and cognitive impairment in patients in a restoration period (3-6 months from the moment of disease) of a cerebral ischemic stroke. Materials and Methods: Research was conducted on the basis of the department of vascular pathology and rehabilitation of the State Institution “Institute of Neurology, Psychiatry and Narcology of the National Academy of Medical Sciences of Ukraine”. Observations were carried out in 84 patients in a restorative period of cerebral ischemic stroke. Patients were divided into two groups. The main group included 43 patients who underwent a course of rehabilitation treatment and received drug therapy within secondary prevention. The comparison group included 41 patients who received only drug therapy for secondary prevention. Results: In the course of the study, it was found that patients who underwent a course of restorative treatment with the use of drug therapy and physical rehabilitation programs received statistically significant improvement in the indicators of cognitive functions by the MMSE, MoCA scales, reduction of manifestations of psycho-emotional disorders that were confirmed by Beck and Spielberger-Khanin scales. Conclusions: Physical rehabilitation of patients in the restorative period of cerebral stroke by ischemic type reduces the degree of expressivness of neurological manifestations, positively affects cognitive functions, contributes to reducing manifestations of depressive and anxiety symptoms, increases the functional capacity of the patient.

Six years’ experience of participation of the Institute of Emergency Medicine from Chisinau, Republic of Moldova in the Registry of Stroke Care Quality

Background. The Institute of Emergency Medicine from Chisinau has joined the Registry of Stroke Care Quality (RES-Q) in 2017. Material and Methods. We have analyzed the stroke patients’ data introduced in RES-Q between 20172022. Baseline characteristics, stroke-related factors, processes of care, and discharge destination were examined. Results. Data were available for 489 stroke patients. The proportion of patients with ischemic strokes receiving thrombolysis therapy has substantially increased from 2.78% in 2017 to 20% in 2022, and the median door-toneedle time decreased from 85 minutes (2017) to 48 minutes (2021). Thrombectomy began to be performed in 2018 at the Institute of Emergency Medicine, the rate of stroke patients receiving thrombectomy increased from 3.23% in 2019 to 10% in 2022, median door-to-groin time decreased from 228.5 minutes in 2019 to 102 minutes in 2021. More than 80% of patients received secondary prevention therapies that were level-1 evidence-based processes of care: antihypertensive agents (89.47% – 98.44%), antiplatelet drugs (81.63% – 100%), anticoagulants for patients with atrial fibrillation (25% in 2018 vs 100% in 2021), but cholesterol-lowering medication was prescribed to approximately a half of the participants (44.23% – 60.0%). There were more deaths in the pandemic years (36.67% in 2021 vs 18.99% in 2017). Conclusion. Most hospitalized stroke patients admitted to the Institute of Emergency Medicine received evidence-based care. The COVID-19 pandemic has left its mark on the number of stroke hospitalizations, but the quality of in-hospital stroke care was not dramatically affected.

Passive Prescription of Secondary Prevention Medical Therapy during Index Hospitalization for Acute Myocardial Infarction Is Prevalent and Associated with Adverse Clinical Outcomes

Secondary prevention therapy reduces death and reinfarction after acute myocardial infarction (AMI), but it is underutilized in clinical practice. Mechanisms for this therapeutic gap are not well established. In this study, we have explored and evaluated the impact of passive continuation compared to active initiation of secondary prevention therapy for AMI during the index hospitalization. For this purpose, we have analyzed 1083 consecutive patients with AMI to a tertiary referral hospital in Hong Kong and assessed discharge prescription rates of secondary prevention therapies (aspirin, beta-blockers, statins, and ACEI/ARBs). Multivariate analysis was used to identify independent predictors of discharge medication, and Kaplan–Meier survival curve was used to evaluate 12-month survival. Overall, prescription rates of aspirin, beta-blocker, statin, and ACEI/ARBs on discharge were 94.8%, 64.5%, 83.5%, and 61.4%, respectively. Multivariate analysis showed that prior use of each therapy was an independent predictor of prescription of the same therapy on discharge: aspirin (odds ratio (OR) = 4.8, 95% CI = 1.9–12.3, P < 0.01), beta-blocker (OR = 2.5, 95% CI = 1.8–3.4, P < 0.01); statin (OR = 8.3, 95% CI = 0.4–15.7, P < 0.01), and ACEI/ARBs (OR = 2.9, 95% CI = 2.0–4.3, P < 0.01). Passive continuation of prior medication was associated with higher 1-year mortality rates than active initiation in treatment-naïve patients (aspirin (13.7% vs. 5.7%), beta-blockers (12.9% vs. 5.6%), and statins (11.0% vs. 4.6%); all P < 0.01). Overall, the use of secondary prevention medication for AMI was suboptimal. Our findings suggested that the practice of passive continuation of prior medication was prevalent and associated with adverse clinical outcomes compared to active initiation of secondary preventive therapies for acute myocardial infarction during the index hospitalization.

Increasing patients’ awareness of their own health: Experiences of participating in follow-up programs after surgical treatment for intermittent claudication

IntroductionClaudication is the most usual symptom of peripheral artery disease, it is described as painful contractions in the leg when walking and alleviated upon resting. People with claudication have an added risk of cardiocerebrovascular events, amputation, and death. Adherence to medical treatment and changes in lifestyles can lower this risk, but this secondary prevention therapy requires engagement, participation, and adherence from the patient. ObjectiveTo explore patients’ experiences of participating in a 1-year multicentre clinical trial with two follow-up programs evaluating a nurse-led, patient-centered health-promoting programme after surgical treatment for claudication, the FASTIC study. MethodsA descriptive design with qualitative semi-structured interviews was used among participants in the FASTIC study. The study was conducted at two centres for vascular surgery in the city of Stockholm, Sweden. In all, 17 patients (nine men and eight women) who had completed the FASTIC study participated. Data was analysed using qualitative content analysis with an inductive approach. ResultsTwo main categories were identified, ‘Patient-Professional collaboration’ and ‘Experience of one´s health’, which were associated with four subcategories: facing opportunities and obstacles, cooperating based on the illness experience, increasing awareness of one's own health, and maintaining a healthy lifestyle. ConclusionsPatients' participation in follow-up programs after surgical treatment for claudication is highly valuable for an increased awareness of one's own health. A person-centered care with patient-professional collaboration is experienced as important for maintaining a health-promoting lifestyle.

Pleiotropic Effects of the Protease-Activated Receptor 1 (PAR1) Inhibitor, Vorapaxar, on Atherosclerosis and Vascular Inflammation

Background: Protease-activated receptor 1 (PAR1) and toll-like receptors (TLRs) are inflammatory mediators contributing to atherogenesis and atherothrombosis. Vorapaxar, which selectively antagonizes PAR1-signaling, is an approved, add-on antiplatelet therapy for secondary prevention. The non-hemostatic, platelet-independent, pleiotropic effects of vorapaxar have not yet been studied. Methods and Results: Cellular targets of PAR1 signaling in the vasculature were identified in three patient cohorts with atherosclerotic disease. Evaluation of plasma biomarkers (n = 190) and gene expression in endomyocardial biopsies (EMBs) (n = 12) revealed that PAR1 expression correlated with endothelial activation and vascular inflammation. PAR1 colocalized with TLR2/4 in human carotid plaques and was associated with TLR2/4 gene transcription in EMBs. In addition, vorapaxar reduced atherosclerotic lesion size in apolipoprotein E–knock out (ApoEko) mice. This reduction was associated with reduced expression of vascular adhesion molecules and TLR2/4 presence, both in isolated murine endothelial cells and the aorta. Thrombin-induced uptake of oxLDL was augmented by additional TLR2/4 stimulation and abrogated by vorapaxar. Plaque-infiltrating pro-inflammatory cells were reduced in vorapaxar-treated ApoEko mice. A shift toward M2 macrophages paralleled a decreased transcription of pro-inflammatory cytokines and chemokines. Conclusions: PAR1 inhibition with vorapaxar may be effective in reducing residual thrombo-inflammatory event risk in patients with atherosclerosis independent of its effect on platelets.

432 ACS-STEMI in a young man with triple positive antiphospholipid syndrome: clinical implications about antithrombotic therapy management

Abstract Antiphospholipid antibody syndrome (APS) is a systemic autoimmune disorder characterized by venous and arterial thromboembolic (TE) disease, and/or pregnancy morbidity, associated with persistent elevated antiphospholipid antibodies (lupus anticoagulant, LA, anticardiolipin, aCL, and anti-beta2-glycoprotein I, anti-β2GPI). A 51 year-old man, smoker, presented to our ER with chest pain. EKG showed Q waves and STE in the anterior leads, with increased troponin levels. A diagnosis of anterior STEMI was made and he was taken into our catheterization laboratory, where a high burden thrombotic plaque determining LM and ostial LAD subocclusion was treated with PPCI and a DES implantation; in addition, multiple failed PCI attempts were performed on a distal LAD occlusion, and an integrilin bolus was administered. The patient was admitted to our CICU and a DAPT with ASA and Ticagrelor was started. TTE showed LVEF 40%, apical akinesis, septal and anterior hypokinesis, and no significant valve disease. An aPTT abnormal value (100.5 s; reference range 25–38.5 s) was detected, not corrected by aPTT mixing study. Given suspected autoimmune prothrombotic state, normal Hb and PLT values and low bleeding risk, LMWH 100 IU/kg every 12 h was started, in addition to DAPT with switch from Ticagrelor to Clopidogrel. LA and aCL and anti-β2GPI IgG were positive, with negativity of others rheumatologic tests, confirming primary APS diagnosis. Repeat TTE showed EF 50%. The patient was discharged in ‘triple therapy’ (DAPT plus LMWH), and referred to the rheumatology clinic. LA, aCL, and anti-β2GPI tests 12 weeks later were positive, confirming a triple positive APS and satisfying revised Sapporo criteria. The rheumatologist switched therapy to Clopidogrel plus Warfarin. At 3 months follow-up, the patient, former smoker, was asymptomatic and TTE confirmed EF 50%, so he was recommended to continue with his medical therapy. APS is rarely associated with AMI (∼5.5%) and in only 2.8% cases AMI represents the onset of the disease. AMI pathogenesis in APS is considered to be acute thrombosis of coronary arteries, in contrast with atherosclerotic plaque rupture in typical AMI. Key discriminators to identify APS as potential underlying cause of AMI include young age, previous unprovoked thromboses, low platelets count (they are consumed in the thrombotic process), high aPTT value (LA may interfere with assembly of the prothrombinase complex on phospholipids), coronary artery thromboses in the setting of otherwise normal otherwise appearing coronary arteries. APS antibodies have also pro-inflammatory activity on vascular endothelial cells, leading to accelerated atherosclerosis. aGAPSS score (high risk ≥10) is useful for risk stratification of recurrent thrombosis and AMI in young patients with APS. The treatment of AMI in APS is therefore a clinical challenge. Strict management of additional CV risk factors is crucial. VKA (INR &amp;gt;3 with Warfarin, INR2–3 with Warfarin and ASA) should be provided for life, because of the very high risk of recurrent TE. DOACs are less effective and less safe than VKAs for TE prevention in APS. The role of coronary stents, considering higher rates of stent thrombosis after PCI in APS patients triple therapy concomitant risks, requires further studies. Due to lack of large, randomized, prospective studies, there is no clear experts consensus about optimal antithrombotic therapy in secondary prevention after arterial TE. APS patients with STEMI should undergo PCI, usually associated with thrombus aspiration, and in selected cases DES implantation in culprit lesion followed by triple antithrombotic therapy with short-term DAPT and long-term VKA.

Lipid lowering therapy in primary and secondary prevention in Austria: are LDL-C goals achieved? : Results from the DAVINCI study.

BackgroundCardiovascular disease (CVD) is the most frequent cause of death in Austria. The European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines recommend intensive lipid lowering therapy (LLT) in patients at high or very high CV risk. Lipid management and achievement of low-density lipoprotein cholesterol (LDL-C) goals in Austria have not recently been assessed.MethodsSubgroup analysis for Austria of a European 18 country, cross-sectional, observational study. Patients received LLT for primary (PP) or secondary prevention (SP). Data including LLT in the preceding 12 months and most recent LDL‑C were collected during a single visit between June 2017 and November 2018. Achievement of the risk-based 2016 and 2019 ESC/EAS LDL‑C goal while receiving stabilized LLT was assessed.ResultsA total of 293 patients were enrolled from 8 Austrian sites, of which 200 (PP = 104, SP = 96) received stabilized LLT at the LDL‑C measurement date. Overall, 58% (71% PP, 43% SP) and 38% (52% PP, 23% SP) achieved the risk-based 2016 and 2019 goals, respectively. Most patients received moderate-intensity statin monotherapy (46%), while 34% used high-intensity statin monotherapy. Combination therapy of moderate/high-intensity statin with ezetimibe (12%), or proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors with statin ± ezetimibe (1%), was used infrequently.ConclusionThe current Austrian routine lipid management using mainly moderate-intensity or high-intensity statin monotherapy is insufficient to attain ESC/EAS guideline goals, in particular the more stringent 2019 recommendations, a situation comparable to other participating European countries. In addition to switching to and optimizing doses of high-intensity statins, a combination with ezetimibe or PCSK9 inhibitors will be needed in many cases.Supplementary InformationThe online version of this article (10.1007/s00508-021-01978-w) contains supplementary material, which is available to authorized users.

Arterial tortuosity syndrome causing recurrent transient ischemic attacks in young adult: a case report

BackgroundArterial Tortuosity Syndrome (ATS) is a rare autosomal recessive disorder characterized by elongated and tortuous arteries. Although ATS showed a significant clinical and pathophysiological overlap with other syndromes involving connective tissues, only few cases of cerebrovascular events related to this syndrome have been described so far.Case presentationWe report the case of a 33-years-old male diagnosed with ATS since childhood, that experienced three sudden episodes of expressive aphasia and right hemiparesis with spontaneous resolution. He was treated with recombinant tissue plasminogen activator (r-TPA) at a dosage of 0.9 mg/kg with a complete recovery. Brain Magnetic Resonance Imaging (MRI) showed the absence of acute ischemic lesions and the patient was diagnosed with recurrent transient ischemic attacks (TIA).Intracranial and supra-aortic trunks Magnetic Resonance Angiography (MRA) and Angio-CT scan of the thoracic and abdominal aorta showed marked vessel tortuosity without stenosis.To our knowledge, this is the first reported case of an ATS patient with TIA in young age that was treated with intravenous thrombolysis with recombinant plasminogen activator.ConclusionOur report strengthens the relationship between ATS and juvenile cerebrovascular events, suggesting that an extensive study of body vessels in order to detect potential stenoses or occlusions in these cases is needed.The greater predisposition to cerebrovascular events in ATS could benefit from a more aggressive primary and secondary prevention therapy.

Secondary prevention implantable cardioverter-defibrillator (ICD) therapy: value in octogenarians

BackgroundImplantable cardioverter-defibrillator (ICD) therapy is well established for secondary prevention, but studies on the efficacy and safety in elderly patients are still lacking. This retrospective study compared the outcome after ICD implantation between octogenarians and other age groups.MethodsData were obtained from a local ICD registry. Patients who received ICD implantation for secondary prevention at our department were included. All-cause mortality, appropriate ICD therapy and acute adverse events requiring surgical intervention were compared between different age groups.Results519 patients were enrolled, 34 of whom were aged ≥ 80 years. During the median follow-up of 35 months after ICD implantation 129 patients (annual mortality rate 5.0%) had died, including 16 patients aged ≥ 80 years (annual mortality rate 9.4%). The mortality rate of patients aged ≥ 80 years was significantly higher than that of patients aged ≤ 69 years (p < 0.001), but similar to that of patients aged 70–79 years. Age at the time of ICD implantation was an independent predictor of all-cause mortality (p < 0.001). 29.7% of patients had appropriate ICD therapy with no difference between age groups. Acute adverse events leading to surgical intervention were low (n = 13) and not age-related.ConclusionAge is an independent predictor of mortality after ICD implantation for secondary prevention. Mortality rates did not differ significantly between octogenarians and other elderly aged 70–79 years. Appropriate ICD therapy and acute adverse events leading to surgical intervention were not age-related. Implantable cardioverter-defibrillator therapy for secondary prevention seems to be an effective and safe treatment modality in octogenarians.
