Routine, intermittent inotropic therapy (IIT) is still applied in advanced heart failure (HF) patients either as a bridge to definitive treatment or as a mean to improve quality of life (QOL), despite limited evidence to support its' use. Given recent reports of improved QOL and reduced HF hospitalization, with levosimendan compared with placebo in advanced HF patients, we aimed to assess the effects of switching a small group of milrinone-treated patients to levosimendan. This was performed as part of a protocol for changing our ambulatory HF clinic milrinone-based IIT to levosimendan.Single-centre study of consecutive ambulatory advanced HF patients that received ≥4 cycles of once-weekly milrinone IIT at our HF outpatient clinic, who were switched to levosimendan IIT. All patients had left ventricular ejection fraction ≤35%, elevated B-natriuretic peptide (BNP), and were in New York Heart Association Classes III-IV despite maximally tolerated guideline directed medical therapy. Patients were evaluated using BNP levels, echocardiography, cardio-pulmonary exercise test, and HF QOL questionnaire before and after 4 weeks of levosimendan IIT. The cohort included 11 patients, 10 (91%) were male and the mean age was 76 ± 12 years. After 4 weeks of levosimendan therapy, maximal OIn this small-scale study of ambulatory advanced HF patients, we observed improvements in right ventricular systolic function, maximal O

Neutrophil-to-lymphocyte ratio (NLR) is a simple and cost-effective marker of inflammation. This marker has been shown to predict cardiac arrhythmias, progression of valvular heart disease, congestive heart failure decompensation, acute kidney injury, and mortality in cardiovascular patients. The pathologic process of aortic stenosis includes chronic inflammation of the valve and therefore biomarkers of inflammation might offer additive prognostic value.To evaluate NLR and its association with long term mortality in transcatheter aortic valve implantation (TAVI) patients.We evaluated data of 1152 consecutive patient from the Tel Aviv Medical Center TAVI registry who underwent TAVI. Data included baseline clinical, demographic, and echocardiographic findings; procedural complications; and post-procedure mortality. Patients were compared by using the median NLR value (4.1) and evaluated for long-term mortality.Patients with NLR above the median had higher mortality rates (26.4% vs. 16.3%, P0.001) at 3 years post-procedure. A multivariable analysis found NLR to be an independent risk factor for mortality (hazard ratio = 1.47, 95% confidence interval 1.09-1.99, P = 0.013). In addition, high NLR was linked to complicationsduring and after the procedure.NLR is an independent prognostic marker among TAVI patients. This marker may represent an increased inflammatory response and should be added to previous known prognostic factors.

Tricuspid regurgitation (TR) is associated with adverse prognosis in various patient populations but currently no data is available about the prevalence and prognostic implication of TR in ST-segment elevation myocardial infarction (STEMI) patients.To investigate the possible implication of TR among STEMI patients.We conducted a retrospective study of STEMI patients undergoing primary percutaneous coronary intervention (PCI), and its relation to major clinical and echocardiographic parameters. Patient records were assessed for the prevalence and severity of TR as well as the relation to the clinical profile, key echocardiographic parameters, in-hospital outcomes, and long-term mortality. Patients with previous myocardial infarction or known previous TR were excluded.The study included 1071 STEMI patients admitted between September 2011 and May 2016 (age 61 ± 13 years; predominantly male). A total of 205 patients (19%) had mild TR while another 32 (3%) had moderate or greater TR. Patients with significant TR demonstrated worse echocardiographic parameters, were more likely to have in-hospital complications, and had higher long-term mortality (28% vs. 6%, P0.001). Following adjustment for significant clinical and echocardiographic parameters, mortality hazard ratio of at least moderate to severe TR remained significant (2.44, 95% confidence interval 1.06-5.6, P = .036) for patients with moderate to severe TR.Among STEMI patients after primary PCI, the presence of moderate to severe TR was independently associated with adverse outcomes and significantly lower survival rate.

Background The resurgence of COVID-19 cases since June 2021, referred to as the fourth COVID-19 wave, has led to the approval and administration of booster vaccines. Our study aims to identify any associations between vaccine status with the characteristics and outcomes of patients hospitalized with severe COVID-19 disease. Methods We retrospectively reviewed all COVID-19 patients admitted to a large tertiary center between July 25 and October 25, 2021 (fourth wave in Israel). Univariant and multivariant analyses of variables associated with vaccine status were performed. Findings Overall, 349 patients with severe or critical disease were included. Patients were either not vaccinated (58%), had the first two vaccine doses (35%) or had the booster vaccine (7%). Vaccinated patients were significantly older, male predominant, and with a higher number of comorbidities including diabetes, hyperlipidemia, ischemic heart disease, heart failure, immunodeficient state, kidney disease and cognitive decline. Time from the first symptom to hospital admission was longer among non-vaccinated patients (7.2 ± 4.4 days, p = 0.002). Critical disease (p Conclusion Hospitalized vaccinated patients with severe COVID-19 had significantly higher rates of most known risk factors for COVID-19 adverse outcomes. Still, all disease outcomes were similar or better compared with the non-vaccinated patients.

SummaryIt was the study objective to evaluate whether chewing a 180 mg loading dose of ticagrelor versus an equal dose of traditional oral administration, enhances inhibition of platelet aggregation 1 hour (h) after administering a ticagrelor loading dose in non-ST elevation myocardial infarction (NSTEMI) patients. Dual anti-platelet therapy represents standard care for treating NSTEMI patients. Ticagrelor is a direct acting P2Y12 inhibitor and, unlike clopidogrel and prasugrel, does not require metabolic activation. Fifty NSTEMI patients were randomised to receive either a chewing loading dose of 180 mg ticagrelor or an equal standard oral dose of ticagrelor. Platelet reactivity was evaluated by VerifyNow at baseline, 1 and 4 h post-loading dose. Results are reported in P2Y12 reaction units. Patients then continued to receive standard 90 mg oral ticagrelor twice daily. Baseline characteristics did not differ between the two groups. P2Y12 reaction units in the chewing group compared with the standard group at 0, 1 and 4 h after ticagrelor loading dose were: 245 vs 239 (p=0.59), 45 vs 130 (p=0.001) and 39 vs 60 (p=0.12), respectively, corresponding to a relative inhibition of platelet aggregation of 83 % vs only 47 % at 1 h (p< 0.001), and 84 % vs 77 % (p=0.59) at 4 h. Major adverse cardiac and cardiovascular events at 30 days were low (2 %), occurring in only one patient in the standard group. In conclusion, chewing a 180 mg ticagrelor loading dose is feasible and facilitates both faster and improved early inhibition of platelet aggregation in NSTEMI patients, compared with a standard oral-loading dose.Supplementary Material to this article is available online at www.thrombosis-online.com.
