Adding Physiotherapists Straight into Main Proper care In a Big Health Care Technique.
Patients with autoimmune connective tissue diseases (CTDs) have a high burden of valvular heart disease and are often thought of as high surgical risk patients.

Patients undergoing aortic valve replacement (AVR) were identified in the Nationwide Readmissions Database between January 2012 and December 2018. Patients with a history of systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, mixed C, Sjögren syndrome, polymyositis, and dermatomyositis were included in the CTD cohort. Patients undergoing coronary artery bypass grafting concomitantly with AVR were excluded. A total of 569 600 hospitalizations were included, of which16 531 (2.9%) had CTD. CTD patients were more likely to be females, with higher rates of heart failure, pulmonary hypertension, and more likely to be insured by Medicare. CTD patients had lower mortality than non-CTD patients [odds ratio (OR) 0.66; 95% confidence interval (CI) 0.59-0.74] and stroke [OR 0.87; 95% (CI) 0.79-0.97]. CTD patients undergoing SAVR had lower mortality [OR 0.69; 95% (CI) 0.60-0.80] and stroke [OR 0.86; 95% (CI) 0.75-0.98). CTD patients undergoing TAVR had lower mortality outcomes [OR 0.67; 95% (CI) 0.56-0.80]; however, they had comparable stroke outcomes [OR 0.97; 95% (CI) 0.83-1.13,
 = 0.69].

Outcomes for patients with CTD requiring AVR are not inferior to their non-CTD counterparts. A comprehensive heart team selection of patients undergoing AVR approaches should place CTD history under consideration; however, pre-existing CTD should not be prohibitive of AVR interventions.

To investigate the additional prognostic value of myocardial work (MW) parameters following acute myocardial infarction (AMI).

Between 2018 and 2020, 244 patients admitted in the cardiac intensive care unit in Lille University Hospital for AMI were included. One-month following AMI, comprehensive transthoracic echocardiography (TTE) was performed to assess parameters of myocardial function. Patients were then followed for major events (ME) cardiovascular death, heart failure, and unplanned coronary revascularization. At 1-month, half of the population was symptomatic (NYHA ≥ II), and medical therapy was almost optimized (angiotensin-converting enzyme inhibitor/angiotensin 2 receptor blocker in 95.5%, beta-blockers in 96.3%, DAPT in 94.7%, and statins in 97.1%). After a median follow-up of 681 (interquartile range 538-840) days, ME occurred in 26 patients (10.7%). Patients presenting ME were older (65.5 ± 14.2 vs. 58.1 ± 12.1years,
 = 0.005) with a higher prevalence of hypertension (65.4 vs. 36.2%,
 = 0.004), more impaired left ventricular (LV) function as assessed by LV ejection fraction (
 = 0.07), global longitudinal strain (
 = 0.03), or MW parameters [
 = 0.01 for global work efficiency (GWE)], and greater LV and left atrium dilatations (
 = 0.06 for left ventricular end-diastolic volume index and
 = 0.03 for left atrial volume index). After adjustment, GWE was the only TTE parameter independently associated with long-term occurrence of ME (
 = 0.02). A GWE value <91% was selected to identify patients at higher ME risk (hazard ratio 95% confidence interval) = 2.94 (1.36-6.35),
 = 0.0041).

Lower GWE at 1 month after AMI is independently associated with higher ME rates. SAR405838 A GWE <91% can improve the post-AMI patient risk stratification.

Mouse models with genetic modifications are required to investigate atherogenesis and associated metabolic syndrome. Adeno-associated virus-8 (AAV8)-mediated overexpression of PCSK9 (AAV8-PCSK9) induces hyperlipidaemia and promotes atherosclerosis in C57BL/6 mice. We aimed to assess whether AAV8-PCSK9-injected C57BL/6 mice fed high-fat diet with added cholesterol (HFD-C) would serve as a model of combined metabolic syndrome and atherosclerosis.

C57BL/6 mice received i.v. injection of AAV-PCSK9 and sex- and age-matched
and C57BL/6 control mice were placed on HFD-C or chow diet for 20 weeks (B6-PCSK9-HFD-C,
HFD-C, B6-HFD-C, and B6-Chow, respectively). High-fat diet with added cholesterol feeding led to insulin resistance and impaired glucose clearance in B6-PCSK9-HFD-C mice compared with B6-Chow controls. This decrease in metabolic health in B6-PCSK9-HFD-C mice as well as the development of atherosclerosis was similar to
HFD-C mice. Importantly, HFD-C feeding induced pancreatic islet hyperplasia in B6-PCSK9-HFD-C and B6-HFD-C compared with B6-Chow controls. In line with alterations in the metabolic phenotype, there was an increase in the number of pro-inflammatory Ly6C
monocytes within the adipose tissues of B6-PCSK9-HFD-C and B6-HFD-C compared with B6-Chow controls.

High-fat diet with added cholesterol-fed AAV-PCSK9-injected C57BL/6 mice can serve as a useful model of integrated metabolic syndrome and atherosclerosis that does not require genetic manipulations.

Frailty is associated with adverse outcomes in older patients with acute coronary syndrome (ACS). The impact of frailty on long-term clinical outcomes following invasive management of non-ST elevation ACS (NSTEACS) is unknown.

The multi-centre Improve Clinical Outcomes in high-risk patieNts with ACS 1 (ICON-1) prospective cohort study consisted of patients aged >75 years undergoing coronary angiography following NSTEACS. Patients were categorized by frailty assessed by Canadian Study of Health and Ageing Clinical Frailty Scale (CFS) and Fried criteria. The primary composite endpoint was all-cause mortality, unplanned revascularization, myocardial infarction, stroke, and bleeding. Of 263 patients, 33 (12.5%) were frail, 152 (57.8%) were pre-frail, and 78 (29.7%) were robust according to CFS. By Fried criteria, 70 patients (26.6%, mean age 82.1 years) were frail, 147 (55.9%, mean age 81.3 years) were pre-frail, and 46 (17.5%, mean age 79.9 years) were robust. The composite endpoint was more common at 5 years among patients with frailty according to CFS (frail 22, 66.7%; pre-frail 81, 53.3%; robust 27, 34.6%,
 = 0.003), with a similar trend when using Fried criteria (frail 39, 55.7%; pre-frail 72, 49.0%; robust 16, 34.8%,
 = 0.085). Frailty measured with both CFS and Fried criteria was associated with the primary endpoint [age and sex-adjusted hazard ratio (HR) compared with robust groups. CFS 2.22, 95% confidence interval (CI) 1.23-4.02,
 = 0.008; Fried HR 1.81, 95% CI 1.00-3.27,
 = 0.048].

In older patients who underwent angiography following NSTEACS, frailty is associated with an increased risk of the primary composite endpoint at 5 years.

Ventricular cardiomyocytes from hypertrophic cardiomyopathy (HCM) patient hearts show prolonged action potential duration (APD), impaired intracellular Ca
homeostasis and abnormal electrical response to beta -adrenergic stimulation. We sought to determine whether this behaviour is associated with abnormal changes of repolarization during exercise and worsening of diastolic function, ultimately explaining the intolerance to exercise experienced by some patients without obstruction.

Non-obstructive HCM patients (178) and control subjects (81) underwent standard exercise testing, including exercise echocardiography. Ventricular myocytes were isolated from myocardial samples of 23 HCM and eight non-failing non-hypertrophic surgical patients. The APD shortening in response to high frequencies was maintained in HCM myocytes, while β-adrenergic stimulation unexpectedly prolonged APDs, ultimately leading to a lesser shortening of APDs in response to exercise. In HCM vs. control subjects, we observed a lesser shing to the reduced exercise tolerance. Our results support the idea that severe electrical cardiomyocyte abnormalities underlie exercise intolerance in a subgroup of HCM patients without obstruction.Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a rare but highly morbid complication after adenoviral vector-based SARS-CoV-2 vaccination. The pre-VITT syndrome is defined as vaccine-induced immune thrombocytopenia without thrombosis typically presenting with new-onset headache. This review aims to identify at-risk patients before complications such as cerebral venous sinus thrombosis occur. We review previously published reports of 19 patients (median age 35 years, range 23-74; 16 females) who met the diagnostic criteria for a pre-VITT syndrome. Seven patients progressed to VITT, 12 patients did not. Patients who experienced VITT received delayed treatment. The median interval between the onset of headache and VITT-treatment (i.e. anticoagulation, immune globulins, or corticosteroids) was 5 days (range 1-8 days) compared with 2 days (0-5 days) in those without subsequent VITT (P = 0.033). The interval from onset of headache to anticoagulation was longer in patients with VITT (median 7 vs. 2 days; range 3-9 vs. 0-7 days; P = 0.01). Anticoagulation was safe in all patients with a pre-VITT syndrome as no haemorrhagic complications occurred after anticoagulation was started despite low platelets. The transient decline of platelet count after admission was significantly more pronounced in patients who progressed to VITT (median 67 vs. 0 × 103/µL; range 0-77 × 103/µL vs. 0-10 × 103/µL; P = 0.005). d-dimers did not differ between groups. Pre-VITT syndrome is a 'red flag' and allows to identify and preemptively treat patients at-risk of further progression to VITT. However, it must be distinguished from post-vaccination immune thrombocytopenia.
The fibrosis-4 (FIB-4) index, calculated using age, platelet count, and levels of aspartate aminotransferase and alanine aminotransferase, is a non-invasive indicator for the detection of liver fibrosis. Advanced hepatic fibrosis is associated with morbidity and mortality in patients with non-alcoholic fatty liver disease. However, the relationship between liver fibrosis and the development of ischaemic heart disease (IHD) has not fully been addressed.

We investigated the association between the FIB-4 index and the new onset of IHD during a 10-year period in a general population of subjects who received annual health examinations (
 = 28 990). After exclusion of subjects with missing data and those with a history of IHD at baseline, a total of 13 448 subjects (men/women 8774/4674, mean age 48 years) were included. During the 10-year period, 378 men (4.3%) and 77 women (1.6%) had a new onset of IHD. Multivariable Cox proportional hazard models with a restricted cubic spline showed that hazard risk for the development of IHD increased with a higher FIB-4 index at baseline after adjustment of age, sex, fatty liver (FL) determined by ultrasonography, estimated glomerular filtration rate, habits of current smoking and alcohol drinking, family history of IHD, and diagnosis of hypertension, diabetes mellitus and dyslipidaemia.
