Statin therapy impact on Long-Term outcomes in acute heart Failure: Retrospective analysis of hospitalized patients.

Background: Statin therapy is well-established for treating hyperlipidemia and ischemic heart disease (IHD), but its role in Acute Decompensated Heart Failure (ADHF) remains less clear. Despite varying clinical guidelines, the actual utilization and impact of statin therapy initiation in patients with ADHF with an independent indication for statin therapy have not been thoroughly explored. Methods: We conducted a retrospective observational study on 5978 patients admitted with ADHF between January 1st, 2007, and December 31st, 2017. Patients were grouped based on their statin therapy status at admission and discharge. We performed multivariable analyses to identify independent predictors of short-term, intermediate-term, and long-term mortality. A sensitivity analysis was also conducted on patients with an independent indication for statin therapy but who were not on statins at admission. Results: Of the total patient cohort, 73.9% had an indication for statin therapy. However, only 38.2% were treated with statins at admission, and 56.1% were discharged with a statin prescription. Patients discharged with statins were younger, predominantly male, and had a higher prevalence of IHD and other comorbidities. Statin therapy at discharge was an independent negative predictor of 5-year all-cause mortality (hazard ratio 0.80, 95% confidence interval 0.76-0.85). The sensitivity analysis confirmed these findings, demonstrating higher mortality rates in patients not initiated on statins during admission. Conclusions: The study highlights significant underutilization of statin therapy among patients admitted with ADHF, even when there's an independent indication for such treatment. Importantly, initiation of statin therapy during hospital admission was independently associated with improved long-term survival.

The safety of sodium glucose transporter 2 inhibitors and trends in clinical and hemodynamic parameters in patients with left ventricular assist devices.

BACKGROUND: The safety and impact of sodium glucose transporter 2 inhibitors (SGLT2-I) in patients with left ventricular assist devices (LVAD) are unknown. METHODS: A retrospective analysis of all consecutive patients who underwent LVAD Heart Mate 3 (HM3) implantation at a single medical center and received SGLT2-I therapy following surgery was conducted. LVAD parameters, medical therapy, laboratory tests, echocardiography, and right heart catheterization (RHC) study results were recorded and compared before and after initiation of SGLT2-I. RESULTS: SGLT2-I medications were initiated in 29 (21%) of 138 patients following HM3 implantation (23 (79%) received Empagliflozin and 6 (21%) Dapagliflozin). The mean age at the time of LVAD implantation was 62 ± 6.7 years, 25 (86%) were male, and 23 (79%) had diabetes mellitus. The median time from HM3 implantation to SGLT2-I initiation was 108 days, IQR (26-477). Following SGLT2-I therapy, the daily dose of furosemide decreased from 47 to 23.5 mg/day (mean difference = 23.5 mg/d, 95% CI 8.2-38.7, p = 0.004) and significant weight reduction was observed (mean difference 2.5 kg, 95% CI 0.7-4.3, p = 0.008). Moreover, a significant 5.6 mm Hg reduction in systolic pulmonary artery pressure (sPAP) was measured during RHC (95% CI 0.23-11, p = 0.042) in a subgroup of 11 (38%) patients. LVAD parameters were similar before and after SGLT2-I initiation (p > 0.2 for all). No adverse events were recorded during median follow-up of 354 days, IQR (206-786). CONCLUSION: SGLT2-I treatment is safe in LVAD patients and might contribute to reduction in patients sPAP.

Significance of Anteroseptal Late Gadolinium Enhancement Among Patients With Acute Myocarditis.

Anteroseptal location of late gadolinium enhancement (LGE) in patients with acute myocarditis (AM) detected by cardiovascular magnetic resonance may indicate an independent marker of unfavorable outcomes according to recent data. We aimed to evaluate the clinical characteristics, management, and inhospital outcomes in patients with AM with positive LGE based on its presence in the anteroseptal location. We analyzed data from 262 consecutive patients hospitalized with a diagnosis of AM with positive LGE within 5 days of hospitalization (n = 425). Patients were divided into 2 groups: those with anteroseptal LGE (n = 25, 9.5%) and those with non-anteroseptal LGE (n = 237, 90.5%). Except for age that was higher in patients with anteroseptal LGE, the demographic and clinical characteristics did not differ significantly between both groups including past medical history, clinical presentation, electrocardiogram parameters, and lab values. Moreover, patients with anteroseptal LGE were more likely to present with reduced left ventricular ejection fraction and to receive congestive heart failure treatments. Although univariate analysis showed that patients with anteroseptal LGE were more likely to have inhospital major adverse cardiac events (28% vs 9%, p = 0.003), there was no difference inhospital outcomes on multivariable analysis between both groups (hazard ratio, 1.17 [95% confidence interval, 0.32 to 4.22], p = 0.81). A higher left ventricular ejection fraction in either echocardiography or cardiovascular magnetic resonance corresponded to better inhospital outcomes regardless of the presence or absence of anteroseptal LGE. In conclusion, the presence of anteroseptal LGE did not confer additional prognostic value for inhospital outcomes.

Surgical ablation for atrial fibrillation: impact of Diabetes Mellitus type 2.

BACKGROUND: Diabetes mellitus (DM) type 2 is an independent risk factor for atrial fibrillation (AF). Surgical ablation or "maze procedure" is an option for patients with AF undergoing concomitant or isolated cardiac surgery. The aim of this study was to evaluate the impact of DM type 2 on early and long-term outcomes of patients following surgical AF ablation. METHODS: We performed an observational cohort study in Israel's largest tertiary care center. All data of patients who underwent surgical AF ablation, between 2006 and 2021 were extracted from our departmental database. Patients were divided into Group I (non-diabetic patients) and Group II (DM type 2 patients). We compared the two groups with respect to freedom from recurrent atrial arrhythmia, and mortality rate. RESULTS: The study population included 606 patients. Group I (non-DM patients), consisting of 484 patients, and Group II (DM type 2 patients), comprised 122 patients. Patients with DM were older, had more hypertension and incidence of cerebrovascular accident (CVA)/transient ischemic attack (TIA), higher EuroSCORE (p < .05 for all), and a longer bypass time-130 ± 40 vs. 122 ± 36 min (p = 0.028). The mean follow-up duration was 39.0 ± 22.7 months. Freedom from atrial fibrillation was similar between the non-DM and DM type 2 groups after a 1-year follow-up, 414 (88.2%) vs. 101 (87.1%) (p = 0.511), after a 3-year follow-up, 360 (86.3%) vs. 84 (79.9%) (p = 0.290) and after a 5-year follow-up, 226 (74.1%) vs. 55 (71.5%) (p = 0.622) respectively. Furthermore, 1- and 3-year mortality was similar between non-DM and DM type 2 groups, 2.5% vs. 4.9%, (p = 0.226) and 5.6% vs. 10.5% (p = 0.076) respectively. 5-year mortality was higher in Group II (DM type 2 patients) compared with Group I (non-DM patients), 11.1% vs. 23.4% (p = 0.009). CONCLUSION: Surgical ablation had a high success rate, with freedom from recurrent atrial arrhythmia at 1- 3- and 5- years follow-up in both the DM type 2 and non-DM groups. Furthermore,1- and 3-year mortality after surgical ablation was also similar in both groups. However, 5-year mortality was higher in the DM type 2 group.

The burden of heart failure in cardiac intensive care unit: a prospective 7 years analysis.

AIMS: The profiles of patients at cardiac intensive care units (CICU) have evolved towards a patient population with an increasing number of co-morbid medical conditions and acute heart failure (HF). The current study was designed to illustrate the burden of HF patients admitted to CICU, and evaluate patient characteristics, in-hospital course and outcomes of CICU patients with HF compared with patients with acute coronary syndrome (ACS). METHODS AND RESULTS: A prospective study including all consecutive patients admitted to the CICU at a tertiary medical centre between 2014 and 2020. The main outcome was a direct comparison between HF and ACS patients in processes of care, resource use, and outcomes during CICU hospitalization. A secondary analysis compared ischaemic versus non-ischaemic HF aetiology. Adjusted analysis evaluated parameters associated with prolonged hospitalization. The cohort included 7674 patients with a total annual CICU admissions of 1028-1145 patients. HF diagnosis patients represented 13-18% of the annual CICU admissions and were significantly older with higher incidence of multiple co-morbidities compared with patients with ACS. HF patients also required more intensive therapies and demonstrated higher incidence of acute complications as compared with ACS patients. Length of stay at the CICU was significantly longer among HF patients compared with patients with ACS (either STEMI or NSTEMI) (6.2 ± 4.3 vs. 4.1 ± 2.5 vs. 3.5 ± 2.1, respectively, P < 0.001). HF patients represented a disproportionately higher amount of total CICU patient days during the study period, as the total length of hospitalization of HF patients was 44-56% out of the total cumulative days in CICU of patients with ACS every year. In hospital mortality rates were also significantly higher among patients with HF compared with STEMI or NSTEMI (4.2% vs. 3.1% vs. 0.7%, respectively, P < 0.001). Despite several differences in baseline characteristics between patients with ischaemic versus non-ischaemic HF, which can be attributed mainly to disease aetiology, hospitalization length and outcomes were similar among the groups regardless of HF aetiology. In multivariable analysis for the risk of prolonged hospitalization in the CICU adjusted to potential significant co-morbidities associated with poor outcomes, HF was found to be an independent and significant parameter associated with the risk of prolonged hospitalization with an OR of 3.5 (95% CI 2.9-4.1, P < 0.001). CONCLUSIONS: Patients with HF in CICU have higher severity of illness with a prolonged and complicated hospital course, all of which can substantially increase the burden on clinical resources.

The Association between Marital Status and Outcomes of Patients Hospitalized with Heart Failure.

BACKGROUND: Little is known about the association between marital status and long-term outcomes of patients hospitalized with heart failure (HF). We aimed to examine the association between marital status and early as well as long-term outcomes of patients hospitalized with HF. METHOD: We analyzed data of 4089 patients hospitalized with HF and were enrolled in the multicenter national survey in Israel between March and April 2003 and were followed until December 2014. Patients were classified into married (N = 2462, 60%) and unmarried (N = 1627, 40%). RESULTS: Married patients were more likely to be males, younger, and more likely to have past myocardial infarction and previous revascularization. Also, they tended to have higher rates of diabetes mellitus (DM) and dyslipidemia, as well as smokers. Survival analysis showed that unmarried patients had higher mortality rates at 1 and 10 years (33% vs. 25%, at 1 year, 89% vs. 80% at 10 years, all p < 0.001). Consistently, multivariable analysis showed that unmarried patients had independently 44% and 35% higher risk of mortality at 1- and 10-year follow-up respectively (1-year HR = 1.44; 95%CI 1.14-1.81; p = 0.002, 10-year HR = 1.35; 95%CI 1.19-1.53; p ≤ 0.001). Other consistent predictors of mortality at both 1- and 10-year follow-up include age, renal failure, and advanced HF. CONCLUSIONS: Being unmarried is independently associated with worse short- and long-term outcomes, particularly among women. Thus, attempts to intensify secondary preventive measures should focus mainly on unmarried patients and mainly women.

Clinical predictors of left ventricular thrombus after myocardial infarction as detected by magnetic resonance imaging.

Background: The diagnosis of a left ventricular (LV) thrombus in patients with ST-segment elevation myocardial infarction (STEMI) remains challenging. The aim of the current study is to characterize clinical predictors for LV thrombus formation, as detected by cardiac magnetic resonance imaging (CMRI). Methods: We retrospectively evaluated 337 consecutive STEMI patients. All patients underwent transthoracic echocardiography (TTE) and CMRI during their index hospitalization. We developed a novel risk stratification model (ThrombScore) to identify patients at risk of developing an LV thrombus. Results: CMRI revealed the presence of LV thrombus in 34 patients (10%), of whom 33 (97%) had experienced an anterior wall myocardial infarction (MI), and the majority (77%) had at least mildly reduced left ventricular ejection fraction (LVEF < 45%). The sensitivity for thrombus formation of the first and second TTE was 5.9% and 59%, respectively. Multivariate logistic regression model revealed that elevated C-reactive protein levels, lack of ST-segment elevation (STe) resolution, elevated creatine phosphokinase levels, and STe in anterior ECG leads are robust independent predictors for developing an LV thrombus. These variables were incorporated to construct the ThrombScore: a simple six-point risk model. The odds ratio for developing thrombus per one-point increase in the score was 3.2 (95% CI 2.1-5.01; p < 0.001). The discrimination analysis of the model revealed a c-statistic of 0.86 for thrombus development. The model identified three distinct categories (I, II, and III) with corresponding thrombus incidences of 0%, 1.6%, and 27.6%, respectively. Conclusion: ThrombScore is a simple and practical clinical model for risk stratification of thrombus formation in patients with STEMI.

The Use of Brain Natriuretic Peptide as a Decision-supporting Tool in Hospitalized Patients.

BACKGROUND: Most dyspneic patients in internal medicine departments have co-morbidities that interfere with the clinical diagnosis. The role of brain natriuretic peptide (BNP) levels is well-established in the acute setting but not in hospitalized patients. OBJECTIVES: To evaluate the additive value of BNP tests in patients with dyspnea admitted to medical wards who did not respond to initial treatment. METHODS: We searched the records of patients who were hospitalized in the department of internal medicine D at Sheba Medical Center during 2012 and were tested for BNP in the ward. Data collected included co-morbidity, medical treatments, diagnosis at presentation and discharge, lab results including BNP, re-hospitalization, and mortality at one year following hospitalization. RESULTS: BNP results were found for 169 patients. BNP was taken 1.7 ± 2.7 days after hospitalization. According to BNP levels, dividing the patients into tertiles revealed three equally distributed groups with a distinctive character. The higher tertile was associated with higher rates of cardiac co-morbidities, including heart failure, but not chronic obstructive pulmonary disease. Higher BNP levels were related to one-year re-hospitalization and mortality. In addition, higher BNP levels were associated with higher rates of in-admission diagnosis change. CONCLUSIONS: BNP levels during hospitalization in internal medicine wards are significantly related to cardiac illness, the existence of heart failure, and patient prognosis. Thus, BNP can be a useful tool in managing dyspneic patients in this setting.

Sex related differences in the characteristics and outcomes of heart failure: A sub analysis of heart failure disease management study.

Aims: This is a sub-analysis of a randomized controlled trial on heart failure (HF) disease management (DM) in which patients with HF (N = 1,360; 27.5% women) were assigned randomly to DM (N = 682) or usual care (UC) (N = 678). Study intervention did not significantly affect the rate of hospital admissions or mortality. This study evaluates sex-related differences in baseline characteristics, clinical manifestations, adherence to treatment and outcomes among the study cohort. Methods: Association between sex and hospital admissions and mortality was tested in multivariable models adjusted for the patients' baseline characteristics. The primary composite outcome of the study included time to first HF hospitalization or all-cause mortality. Secondary composite outcome included number of hospital admissions and days of hospitalization, for HF and all other causes. Results: Compared to males, females recruited in the study were on average 3 years older [median age 72 (62, 78) vs. 75 (65, 82), p = 0.001], with higher prevalence of preserved left ventricular function (LVEF ≥50%) and lower frequency of ischemic heart disease (IHD) (p ≤ 0.001). Females had shorter 6-min walking distance and worse quality of life and depression scores at baseline (p < 0.001). The proportion of patients receiving HF recommended medical treatment was similar among females and males. During a median follow-up of 2.7 years (range: 0-5), there were no significant differences between females and males with respect to the time elapsed until the study primary endpoint and its components in univariate analysis [557 (56.5%) males and 218 (58.3%) females were hospitalized for HF or died for any cause; p > 0.05]. Multivariable analysis showed that females were significantly less likely than males to experience the primary outcome [adjusted hazard ratio (HR) = 0.835, 95% CI: 0.699, 0.998] or to die from any cause [adjusted HR = 0.712; 95%CI: 0.560, 0.901]. The sex-related mortality differences were especially significant among patients with non-preserved EF, with IHD or with recent HF hospitalization. Females also had lower rates of all-cause hospital admissions [adjusted rate ratio = 0.798; 95%CI: 0.705, 0.904] and were more likely to adhere to HF medical therapy compared to males. Conclusion: Females with HF fare better than men. Sex related differences were not explained by baseline and morbidity-related characteristics or adherence to medical treatment.

Effect of levosimendan infusion prior to left ventricular assist device implantation on right ventricular failure.

OBJECTIVE: Investigate the safety and efficacy of preoperative levosimendan in patients undergoing left ventricular assist device (LVAD) implantation. METHODS: Consecutive patients who received LVADs (HeartMate-2, 3, HVAD) in a single tertiary medical center (2012-2018). INTERMACS profile 1 patients were excluded. The primary outcome was post-LVAD right ventricular failure (RVF) and inhospital mortality rates. The secondary outcomes included other clinical, echocardiographic and hemodynamic parameters at follow-up. RESULTS: Final cohort consisted of 62 patients (40[65%] in the levosimendan group and 22[35%] in the no-levosimendan group). Post-operative RVF rate and inotrope or ventilation support time were similar in the levosimendan and no-levosimendan groups (7.5% vs. 13.6%; P = 0.43, median of 51 vs. 72 h; P = 0.41 and 24 vs. 27 h; P = 0.19, respectively). Length of hospitalization, both total and in the intensive care unit, was not statistically significant (median days of 13 vs. 16; P = 0.34, and 3 vs. 4; P = 0.44, respectively). Post-operative laboratory and echocardiographic parameters and in-hospital complication rate did not differ between the groups, despite worse baseline clinical parameters in the Levosimendan group. There was no significant difference in the in-hospital and long term mortality rate (2.5% vs. 4.5%; P > 0.999 and 10% vs. 27.3% respectively; P = 0.64). CONCLUSIONS: Levosimendan infusion prior to LVAD implantation was safe and associated with comparable results without significant improved post-operative outcomes, including RVF.

Hemodynamic Changes After Left Ventricular Assist Device Implantation Among Heart Failure Patients With and Without Elevated Pulmonary Vascular Resistance.

Background: Left ventricular assist devices (LVADs) may reverse elevated pulmonary vascular resistance (PVR) which is associated with worse prognosis in heart failure (HF) patients. We aim to describe the temporal changes in hemodynamic parameters before and after LVAD implantation among patients with or without elevated PVR. Methods: HF patients who received continuous-flow LVAD (HeartMate 2&3) at a tertiary medical center and underwent right heart catheterization with PVR reversibility study before and after LVAD surgery. Patients were divided into 3 groups: normal PVR (<4WU); reversible PVR (initial PVR ≥4WU with positive reversibility); and non-reversible (persistent PVR ≥4WU). Results: Overall, 85 LVAD patients with a mean age of 58 years (IQR 49-64), 65 patients (76%) were male; 60 patients had normal PVR, 20 patients with reversible and 5 patients with non-reversible PVR pre-LVAD. All patients with elevated PVR (≥4WU) had higher pulmonary pressures (PP) and increased trans-pulmonary gradient (TPG) compared to patients with normal PVR (p < 0.05). Patients with non-reversible PVR were more likely to have a significantly lower baseline cardiac output (CO) compared to all other groups (p ≤ 0.02). Hemodynamic parameters and PVR post LVAD were similar in all study groups. Patients with baseline elevated PVR (reversible and non-reversible) demonstrated a significant improvement in PP and TPG compared to patients with normal baseline PVR (p ≤ 0.05). The improvement in CO and PVR post-LVAD in the non-reversible PVR group was significantly greater compared to all other groups (p < 0.01). There were no significant differences between study groups in post LVAD and post heart transplantation course. Conclusion: Hemodynamic parameters improved after LVAD implantation, regardless of baseline PVR and reversibility, and enabled heart transplantation in patients who were ineligible due to non-reversible elevated PVR. Our findings suggest that mitigation of elevated non-reversible PVR is related to reduction in PP and increase in CO.

Diastolic Plateau - Invasive Hemodynamic Marker of Adverse Outcome Among Left Ventricular Assist Device Patients.

Background: Diastolic plateau is an invasive hemodynamic marker of impaired right ventricular (RV) diastolic filling. The purpose of the current analysis was to evaluate the prognostic importance of this sign in left ventricular assist device (LVAD) patients. Methods: The analysis included all LVAD patients who received continuous-flow LVAD (HeartMate 3) at the Sheba medical center and underwent right heart catheterization (RHC) during follow up post-LVAD surgery. Patients were dichotomized into 2 mutually exclusive groups based on a plateau duration cutoff of 55% of diastole. The primary end point of the current analysis was the composite of death, heart transplantation, or increase in diuretic dosage in a 12-month follow-up period post-RHC. Results: Study cohort included 59 LVAD patients with a mean age of 57 (IQR 54-66) of whom 48 (81%) were males. RHC was performed at 303 ± 36 days after LVAD surgery. Patients with and without diastolic plateau had similar clinical, echocardiographic, and hemodynamic parameters. Kaplan-Meier survival analysis showed that the cumulative probability of event at 1 year was 65 ± 49% vs. 21 ± 42% for primary outcomes among patients with and without diastolic plateau (p Log rank < 0.05 for both). A multivariate model with adjustment for age, INTERMACS score and ischemic cardiomyopathy consistently showed that patients with diastolic plateau were 4 times more likely to meet the study composite end point (HR = 4.35, 95% CI 1.75-10.83, p = 0.002). Conclusion: Diastolic plateau during RHC is a marker of adverse outcome among LVAD patients.

Characterization of heart failure patients with reverse left ventricular remodelling post-angiotensin receptor blockers/neprilysin inhibitors therapy.

AIMS: To assess the effect of angiotensin receptor blockers/neprilysin inhibitors (ARNI) on left ventricular (LV) ejection fraction (LVEF) and LV dimensions in a real-life cohort of heart failure and reduced ejection fraction (HFrEF) patients, while analysing patient characteristics that may predict reverse LV remodelling. METHODS AND RESULTS: The ARNI-treated HFrEF patients followed at a single tertiary medical centre HF-outpatient clinic were included in the study. Clinical and echocardiographic parameters were evaluated prior to ARNI initiation, and while on ARNI therapy, assessing patient characteristics associated with reverse LV remodelling. The cohort included 91 patients (mean age 60.5 years, 90% male) and 47 (52%) patients exhibited ARNI responsiveness, defined as an increase in LVEF during therapy. Overall, LVEF increased by 19% post-ARNI (23.8 to 28.4%, P < 0.001). Subgroup analysis revealed several parameters associated with significant LVEF improvement, including baseline LVEF <30%, non-ischaemic HF aetiology, lack of cardiac resynchronization therapy (CRT), better initial functional class and ARNI initiation within 3 years from HF diagnosis (P ≤ 0.001 for all). Significant reduction in LV dimensions was noted in patients with lower initial LVEF, non-ischaemic HF and no CRT. Further combined subgrouping of the study population demonstrated that patients with both LVEF <30% and a non-ischaemic HF gained most benefit from ARNI with an average of 51% improvement in LVEF (19.9 to 30%, P < 0.001). CONCLUSIONS: The ARNI treatment response is not uniform among HFrEF patient subgroups. More pronounce reverse LV remodelling is associated with early ARNI treatment initiation in the course of HFrEF, and in those with LVEF <30%, non-ischaemic HF and no CRT.

The impact of diabetes on short-, intermediate- and long-term mortality following left ventricular assist device implantation.

OBJECTIVES: Type 2 diabetes mellitus (DM) is a frequent comorbidity among patients suffering from advanced heart failure necessitating a left ventricular assist device (LVAD) implant. The goal of this study was to evaluate the impact of type 2 DM on early and long-term outcomes of patients following an LVAD implant. METHODS: We performed an observational cohort study in a large tertiary care centre in Israel. All data of patients who underwent a continuous flow LVAD implant between 2006 and 2020 were extracted from our departmental database. Patients were divided into 2 groups: group I (patients without diabetes) and group II (patients with diabetes). We compared short-term (30-day and 3-month) mortality, intermediate-term (1- and 3-year) mortality and long-term (5 year) mortality between the 2 groups. RESULTS: The study population included 154 patients. Group I (patients without diabetes) comprised 88 patients and group II (patients with diabetes) comprised 66 patients. The mean follow-up duration was 38.2 ± 30.3 months. Short- and intermediate-term mortality (30 days, 1 year and 3 years) was higher in the group with DM compared with the group without DM but did not reach any statistically significant difference: 16.1% vs 9.8% (P = 0.312), 24.2% vs 17.3% (P = 0.399) and 30.6% vs 21.9% (P = 0.127) respectively. Long-term 5-year mortality was significantly higher in the group with DM compared to the group without: 38.7% vs 24.4% (P = 0.038). Furthermore, predictors of long-term mortality included diabetes (hazard ratio 2.09, confidence interval 1.34-2.84, P = 0.004), as demonstrated by regression analysis. CONCLUSIONS: Patients with diabetes and those without diabetes have similar 30-day and short- and intermediate-term mortality rates. The mortality risk of diabetic patients begins to increase 3 years after an LVAD implant. Diabetes is an independent predictor of long-term, 5-year mortality after an LVAD implant.

Low ALT levels are associated with poor outcomes in acute coronary syndrome patients in the intensive cardiac care unit.

BACKGROUND: Frailty is an underrecognized and important entity that bears worse prognosis. Although low serum alanine aminotransferase (ALT) can serve as a novel marker of frailty, its use was never assessed in acute coronary syndrome (ACS) patients. METHODS: A retrospective analysis of hospitalized ACS patients in the intensive cardiac care unit (ICCU)between 1/5/2011 and 1/12/2020 at a single tertiary medical center. RESULTS: The study included 3956 patients after excluding patients with ALT >40 IU/L, cirrhosis, and missing data, followed for a medianduration of 47 months (IQR 20-77).Patients were stratified into two groups based on their first ALT measurement within the index hospitalization: low-normal ALT group (ALT ≤10 IU/L) vs. high-normal ALT group (ALT >10 IU/L). Patients with ALT≤10 IU/L were older (mean age 71 years vs. 65 years, p<0.001), presented more frequently with non-ST elevation myocardial infarction (66.4% vs. 53.2%, p< 0.001), had higher rates of comorbiditiesat baseline, and had a lower Norton score upon admission. Hospitalization length was longer in the low-normal ALT group (p< 0.001). Although the in-hospital mortality rate was similar between the groups (0.9% vs. 0.7%, p = 0.99), long-termmortality was significantly higher in the low-normal ALT group (22.7% vs. 7.9%, p< 0.001). In a multivariate regression model ALT ≤10 IU/l was associated with increased mortality (HR 2.1, 95% CI 1.46-3). CONCLUSIONS: Lower serum ALT is associated with worse outcomes in ACS patients admitted to the ICCU.

PESI score for predicting clinical outcomes in PE patients with right ventricular involvement.

Pulmonary embolism (PE) patients with right ventricular (RV) involvement are a heterogenous group who mandate further risk stratification. Our objective was to evaluate the efficacy of the PE severity index (PESI) for predicting adverse clinical outcomes among PE patients with RV involvement. Consecutive normotensive PE patients with RV involvement were allocated according to admission PESI score (PESI ≤ III vs. PESI ≥ IV). The primary outcome included hemodynamic instability and in-hospital mortality. Secondary outcomes included each component of the primary outcome as well as mechanical ventilation, thrombolytic therapy, acute kidney injury, and major bleeding. Multivariable logistic regression model was performed to assess the independent association between the PESI score and primary outcome. C-Statistic was used to compare the PESI with the BOVA score. A total of 253 patients were evaluated: 95 (38%) with a PESI ≥ IV. Of them, 82 (32%) patients were classified as intermediate-low risk and 171 (68%) as intermediate-high risk. Fifty (20%) patients had at least 1 adverse event. Multivariate analysis demonstrated the PESI to be an independent predictor for the primary outcome (HR 4.81, CI 95%, 1.15-20.09, p = 0.031), which was increased with a concomitant increase of the PESI score (PESI I 4.2%, PESI II 3.4%, PESI III 12%, PESI IV 16.3%, PESI V 23.1%, p for trend < 0.001). C-Statistic analysis for the PESI score yielded an AUC-0.746 (0.637-0.854), p = 0.001, compared to the BOVA score: AUC-0.679 (0.584-0.775), p = 0.011. PESI score was found to predict adverse outcomes among normotensive PE patients with RV involvement.

HeartMate 3: new challenges in ventricular tachycardia ablation.

AIM: To describe clinical characteristics, procedural details, specific challenges, and outcomes in patients with HeartMate3™ (HM3), a left ventricular assist device system with a magnetically levitated pump, undergoing ventricular tachycardia ablation (VTA). METHODS AND RESULTS: Data were collected from patients with an HM3 system who underwent VTA in seven tertiary centres. Data included baseline patient characteristics, procedural data, mortality, and arrhythmia-free survival. The study cohort included 19 patients with cardiomyopathy presenting with ventricular tachycardia (VT) (53% with VT storm). Ventricular tachycardias were induced in 89% of patients and a total of 41 VTs were observed. Severe electromagnetic interference was present on the surface electrocardiogram. Hence, VT localization required analysis of intra-cardiac signals or the use of filter in the 40-20 Hz range. The large house pump HM3 design obscured the cannula inflow and therefore multi imaging modalities were necessary to avoid catheter entrapment in the cannula. A total of 32 VTs were mapped and were successfully ablated (31% to the anterior wall, 38% to the septum and only 9% to the inflow cannula region). Non-inducibility of any VT was reached in 11 patients (58%). Over a follow-up of 429 (interquartile range 101-692) days, 5 (26%) patients underwent a redo VT ablation due to recurrent VTA and 2 (11%) patients died. CONCLUSIONS: Ventricular tachycardia ablation in patients with HM3 is feasible and safe when done in the appropriate setup. Long-term arrhythmia-free survival is acceptable but not well predicted by non-inducibility at the end of the procedure.

Navigating between Scylla and Charybdis: challenges and strategies for implementing guideline-directed medical therapy in heart failure with reduced ejection fraction.

Guideline-directed medical therapy (GDMT) has the potential to reduce the risks of mortality and hospitalisation in patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, real-world data indicate that many patients with HFrEF do not receive optimised GDMT, which involves several different medications, many of which require up-titration to target doses. There are many challenges to implementing GDMT, the most important being patient-related factors (comorbidities, advanced age, frailty, cognitive impairment, poor adherence, low socioeconomic status), treatment-related factors (intolerance, side-effects) and healthcare-related factors that influence availability and accessibility of HF care. Accordingly, international disparities in resources for HF management and limited public reimbursement of GDMT, coupled with clinical inertia for treatment intensification combine to hinder efforts to provide GDMT. In this review paper, authors aim to provide solutions based on available evidence, practical experience, and expert consensus on how to utilise evolving strategies, novel medications, and patient profiling to allow the more comprehensive uptake of GDMT. Authors discuss professional education, motivation, and training, as well as patient empowerment for self-care as important tools to overcome clinical inertia and boost GDMT implementation. We provide evidence on how multidisciplinary care and institutional accreditation can be successfully used to increase prescription rates and adherence to GDMT. We consider the role of modern technologies in advancing professional and patient education and facilitating patient-provider communication. Finally, authors emphasise the role of novel drugs (especially sodium-glucose co-transporter 2 inhibitors), and a tailored approach to drug management as evolving strategies for the more successful implementation of GDMT.
