RESUMEN
Background: Acute Decompensated Heart Failure (ADHF) is associated with frequent hospitalizations, posing a significant health and economic burden globally. Despite advancements in heart failure management, studies delineating temporal trends in ADHF outcomes are sparse.Methods: in this retrospective analysis, ADHF patients admitted to Shamir Medical Center from 2007 to 2017 were categorized into two cohorts: early (2007-2011) and recent (2012-2017). Clinical characteristics, in-hospital interventions, and outcomes were compared. Survival analysis was performed using Kaplan-Meier methods with log-rank tests. Results: 8332 admitted patients were analyzed, 4366 (52.4 %) in the early period, and 3966 (47.6 %) in the recent period. In the recent cohort, ischemic heart disease decreased significantly (from 45.2 % to 34.7 %), while hypertension and smoking rates increased. Additionally, a significant increase in coronary artery bypass grafting (from 0.8 % to 3.5 %) and beta-blockers prescription (from 45.5 % to 63.4 %) post-discharge was observed. However, no substantial improvement in in-hospital mortality (8.9 % in early vs. 8.0 % in recent), 30-day (3.2 % in early vs. 3.1 % in recent), 1-year (23.3 % in early vs. 23.8 % in recent), or 5-year survival rates was noted between cohorts. A subset analysis of patients admitted to cardiology departments showed a significant reduction in in-hospital mortality in the recent cohort (12.3 % in early vs. 6.3 % in recent), yet without a corresponding long-term survival benefit. Conclusions: Advancements in heart failure management over the 11-year study period did not demonstrate an improvement in clinical outcomes for ADHF patients, highlighting the challenge of translating advancements in the medical care of ADHF patients into long-term survival benefits.
RESUMEN
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.
RESUMEN
This study shows that we can use synthetic cohorts created from medical risk calculators to gain insights into how risk estimations, clinical reasoning, data-driven subgrouping, and the confidence in risk calculator scores are connected. When prediction variables aren't evenly distributed in these synthetic cohorts, they can be used to group similar cases together, revealing new insights about how cohorts behave. We also found that the confidence in predictions made by these calculators can vary depending on patient characteristics. This suggests that it might be beneficial to include a "normalized confidence" score in future versions of these calculators for healthcare professionals. We plan to explore this idea further in our upcoming research.

(1) Background: The "obesity paradox" refers to a protective effect of higher body mass index (BMI) on mortality in acute infectious disease patients. However, the long-term impact of this paradox remains uncertain. (2) Methods: A retrospective study of patients diagnosed with community-acquired acute infectious diseases at Shamir Medical Center, Israel (2010-2020) was conducted. Patients were grouped by BMI: underweight, normal weight, overweight, and obesity classes I-III. Short- and long-term mortality rates were compared across these groups. (3) Results: Of the 25,226 patients, diverse demographics and comorbidities were observed across BMI categories. Short-term (90-day) and long-term (one-year) mortality rates were notably higher in underweight and normal-weight groups compared to others. Specifically, 90-day mortality was 22% and 13.2% for underweight and normal weight respectively, versus 7-9% for others (p < 0.001). Multivariate time series analysis revealed underweight individuals had a significantly higher 5-year mortality risk (HR 1.41 (95% CI 1.27-1.58, p < 0.001)), while overweight and obese categories had a reduced risk (overweight-HR 0.76 (95% CI 0.72-0.80, p < 0.001), obesity class I-HR 0.71 (95% CI 0.66-0.76, p < 0.001), obesity class II-HR 0.77 (95% CI 0.70-0.85, p < 0.001), and obesity class III-HR 0.79 (95% CI 0.67-0.92, p = 0.003)). (4) Conclusions: In this comprehensive study, obesity was independently associated with decreased short- and long-term mortality. These unexpected results prompt further exploration of this counterintuitive phenomenon.
RESUMEN
BACKGROUND: Conflicting evidence exists regarding the association between marital status and outcomes in patients with heart failure (HF). Further, it is not clear whether type of unmarried status (never married, divorced, or widowed) disparities exist in this context. HYPOTHESIS: We hypothesized that marital status will be associated with better outcomes in patients with HF. METHODS: This single-center retrospective study utilized a cohort of 7457 patients admitted with acute decompensated HF (ADHF) between 2007 and 2017. We compared baseline characteristics, clinical indices, and outcomes of these patients grouped by their marital status. Cox regression analysis was used to explore the independency of the association between marital status and long-term outcomes. RESULTS: Married patients accounted for 52% of the population while 37%, 9%, and 2% were widowed, divorced, and never married, respectively. Unmarried patients were older (79.8 ± 11.5 vs. 74.8 ± 11.1 years; p < 0.001), more frequently women (71.4% vs. 33.2%; p < 0.001), and less likely to have traditional cardiovascular comorbidities. Compared with married patients, all-cause mortality incidence was higher in unmarried patients at 30 days (14.7% vs. 11.1%, p < 0.001), 1 year, and 5 years (72.9% vs. 68.4%, p < 0.001). Nonadjusted Kaplan-Meier estimates for 5-year all-cause mortality by sex, demonstrated the best prognosis for married women, and by marital status in unmarried patients, the best prognosis was demonstrated in divorced patients while the worst was recorded in widowed patients. After adjustment for covariates, marital status was not found to be independently associated with ADHF outcomes. CONCLUSIONS: Marital status is not independently associated with outcomes of patients admitted for ADHF. Efforts for outcomes improvement should focus on other, more traditional risk factors.

Early detection of left ventricular systolic dysfunction (LVSD) may prompt early care and improve outcomes for asymptomatic patients. Standard 12-lead ECG may be used to predict LVSD. We aimed to compare the performance of Machine Learning Algorithms (MLA) and physicians in predicting LVSD from a standard 12-lead ECG. By utilizing a dataset of 13,820 pairs of ECGs and echocardiography, a deep residual convolutional neural network was trained for predicting LVSD (ejection fraction (EF) < 50%) from ECG. The ECGs of the test set (n = 850) were assessed for LVSD by the MLA and six physicians. The performance was compared using sensitivity, specificity, and C-statistics. The interobserver agreement between the physicians for the prediction of LVSD was moderate (κ = 0.50), with average sensitivity and specificity of 70%. The C-statistic of the MLA was 0.85. Repeating this analysis with LVSD defined as EF < 35% resulted in an improvement in physicians' average sensitivity to 84% but their specificity decreased to 57%. The MLA C-statistic was 0.88 with this threshold. We conclude that although MLA outperformed physicians in predicting LVSD from standard ECG, prior to robust implementation of MLA in ECG machines, physicians should be encouraged to use this approach as a simple and readily available aid for LVSD screening.
RESUMEN
BACKGROUND: The European Society of Cardiology (ESC) guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation (non-ST-segment elevation myocardial infarction [NSTEMI]) has recommended immediate (<2 h) percutaneous coronary intervention (PCI) in very-high risk patients and early (<24 h) PCI in high-risk patients. HYPOTHESIS: To examine the ESC NSTEMI guidelines adherence in a nationwide survey in Israel using the Acute Coronary Syndrome Israeli Survey (ACSIS). We hypothesized that adherence to the guidlines' recommnded PCI timing in NSTEMI pateints will be inadequate, partly due to the inconsistent evidence regarding its effect on clinical outcomes. METHODS: All NSTEMI patients who underwent PCI during the ACSIS surveys in 2016 and 2018 were included in the analysis. RESULTS: Out of 1793 NSTEMI patients, 1643 (92%) patients underwent PCI, and door to balloon time was documented in 1078 of them. One hundred and fifty-six (14.5%) patients and 922 (85.5%) patients were defined as very high-risk and high-risk NSTEMI patients, respectively. Of the very high-risk NSTEMI patients, only 10 (6.4%) underwent immediate coronary angiography, and 50 (32.1%) underwent early coronary angiography. Acute heart failure 139 (89.1%) was the main reason for including NSTEMI patients in the very high-risk category. Of the high-risk patients, early coronary angiography was performed in only 405 (43.9%) patients. Patients in whom coronary angiography was postponed were older and had more comorbidities. CONCLUSIONS: Despite guidelines recommendations for immediate and early PCI in very high-risk and high-risk NSTEMI patients, respectively, most patients do not undergo immediate or early PCI according to contemporary guidelines. Further studies are needed to better understand the reasons for guidelines' nonadherence in those high-risk patients.

RESUMEN
BACKGROUND: Post-procedure readmissions are associated with lower quality of life and increased economic burden. The study aimed to identify predictors for long-term all-cause readmissions in patients who underwent transcatheter aortic valve replacement (TAVR) in a community hospital. METHODS: A Historical cohort study of all adults who underwent TAVR at Cape-Cod hospital between June 2015 and December 2017 was performed and data on readmissions was collected up-to May 2020 (median follow up of 3.3 years). Pre-procedure, procedure and in-hospital post-procedure parameters were collected. Readmission rate was evaluated, and univariate and multivariable analyses were applied to identify predictors for readmission. RESULTS: The study included 262 patients (mean age 83.7±7.9 years, 59.9% males). The median Society of Thoracic Surgeons (STS) probability of mortality (PROM) score was 4.9 (IQR, 3.1-7.9). Overall, 120 patients were readmitted. Ten percent were readmitted within 1-month, 20.8% within 3-months, 32.0% within 6-months and 44.5% within 1-year. New readmissions after 1-year were rare. STS PROM 5% or above (HR 1.50, p = 0.039), pre-procedure anemia (HR 1.63, p = 0.034), severely decreased pre-procedure renal function (HR 1.93, p = 0.040) and procedural complication (HR 1.65, p = 0.013) were independent predictors for all-cause readmission. CONCLUSIONS: Elevated procedural risk, anemia, renal dysfunction and procedural complication are important predictors for readmission. Pre-procedure and ongoing treatment of the patient's background diseases and completion of treatment for complications prior to discharge may contribute to a reduction in the rate of readmissions.

BACKGROUND: Polycythemia has not been extensively studied for its impact on acute coronary syndrome (ACS) outcomes. A previous study reported only 30-day outcomes to be worse in these patients. METHODS: Data from the ACS Israeli survey between 2000 and 2018 were utilized to compare between 3 groups of patients with ACS: anemic group (hemoglobin <12 g/dL for women and <12.5 g/dL for men), normal hemoglobin group, and polycythemic group (>16 g/dL and >16.5 g/dL, respectively). Measured outcomes included 30-day major adverse cardiac events (MACE comprising all-cause mortality, recurrent ACS, need for urgent revascularization, and stroke) and 1- and 5-year all-cause mortality. RESULTS: Of 14,746 ACS patients, 10,752 (72.9%) had normal hemoglobin levels, 3,492 (23.7%) were anemic, and 502 (3.4%) were polycythemic. In comparison with normal and anemic patients, polycythemic patients were younger (55.9 ± 10.5 vs. 61.9 ± 12.4 and 71.1 ± 12.2 for anemic, respectively, p < 0.001 for both), more frequently men (93.8% vs. 81.3% and 63.1%, respectively, p < 0.001), and less likely diabetic or hypertensive. Upon adjustment to baseline characteristics, compared with normal hemoglobin, polycythemia was not independently associated with 30-day MACE or 1-year mortality, but it was independently associated with higher risk for 5-year mortality (HR 1.76, 95% CI: 1.19-2.59, p = 0.005). Similar results were observed after propensity score matching. CONCLUSIONS: Although younger and with fewer comorbidities, polycythemic ACS patients are at increased risk for long-term all-cause mortality. Further study of this association is warranted to understand the causes and possibly to improve the outcomes of these patients.

BACKGROUND: Non-Vitamin K antagonist oral anticoagulants (NOACs) emerged as an alternative with comparable or superior efficacy and safety to vitamin K antagonists (VKAs) for stroke prevention in patients with non-valvular atrial fibrillation (AF). OBJECTIVES: The aim of the current study was to investigate the patterns, predictors, timelines and temporal trends of shifting from VKAs to NOACs. METHODS: In this retrospective observational study, the computerized database of a large healthcare provider in Israel, Maccabi Healthcare Services, was searched to identify patients with AF for whom either a VKA or NOAC was prescribed between 2012 and 2015. Time from diagnosis to therapy initiation and to shifting between therapies was evaluated. RESULTS: Out of 6987 eligible AF incident patients, 2338 (33.4%) initiated treatment with a VKA and 2221 (31.7%) with a NOAC. In addition, 5259 prevalent patients were analyzed. During the study period, NOAC prescriptions proportion among the newly diagnosed cases increased from 32 to 68.4% (p for trend < 0.001). The median time from diagnosis to first dispensing was greater in NOAC than VKA and decreased among patients treated with NOAC during the study period (2012: 1.9 and 0.3 months, 2015: 0.7 and 0.2 months, respectively). During follow-up, 3737 (49%) patients (54.3% and 47.1% of the incident and prevalent cases, respectively), shifted from a VKA to a NOAC, after a median of 22 months and 39 months in the incident and prevalent cases, respectively, decreasing throughout the study period. Female gender, younger age, southern district, higher CHADS2 and CHA2DS2-VASC score, non-smoking, and treatment with antiplatelets were associated with a greater likelihood for therapy shift. Shifting from a NOAC to a VKA decreased over time from 8 to 4.5% in 2012 to 0.5% and 0.7% in 2015 in the incident and prevalent groups, p < 0.001 respectively. CONCLUSIONS: Shifting from VKA to NOAC occurred in 50% of the cases, more frequently among incident cases, and younger patients with greater stroke risk. Shifting from a NOAC to a VKA was much less frequent, yet it occurred more often in incident cases and decreased over time. A socially and economically sensitive program to optimize the initiation of OAC therapy upon diagnosis is warranted.

OBJECTIVES: This study aimed to compare permanent pacemaker implantation (PPMI) rates among patients undergoing Trans-catheter Aortic Valve Implantation (TAVI) with first generation (G1) versus second generation (G2) valves and the impact of PPMI on long-term mortality. BACKGROUND: PPMI is a known adverse event after TAVI. Recently, two novel iterations of valve designs of both the balloon expandable valves (BEV) and self-expanding valves (SEV) were introduced as a second generation valves. METHODS: All patients included in the Israeli multicenter TAVI registry were grouped according to valve type (BEV vs. SEV) and generation (G1 vs. G2). A comparison was made for clinical and outcome indices of patients undergoing TAVI with G1 and G2 in each of the valve systems. RESULTS: A total of 1377 patients were included. The incidence of PPMI did not differ between G1-BEV versus G2-BEV (15.3% vs. 17.4%; p = 0.598) nor between G1-SEV versus G2-SEV (23.4% vs. 20.3%; p = 0.302). Depth of implantation and complete right bundle branch block were independently associated with PPMI post-TAVI in both valve systems. PPMI was not associated with an increased risk for 2-year mortality. CONCLUSIONS: The incidence of PPMI remains a relevant adverse event post-TAVI even when the newer generation valves are used. Since the predictors for PPMI are well established, a standardized approach for the management of conduction disorders is much needed.

BACKGROUND: Hypertension in dialysis patients is common. In daily practice, it is not always clear whether adjustment of dry weight or vasodilatory medication should be administered and treatment strategy is often based on clinical impression. We used a whole-body bio-impedance based, non-invasive, hemodynamics monitoring technology to acquire hemodynamic data in order to evaluate the incidence and causes of hypertension in dialysis patients. METHODS: Novel noninvasive impedance based technique was used to collect hemodynamic data from patients undergoing chronic hemodialysis in four different dialysis units. Patients were defined as having hypertension if their predialysis systolic or diastolic BP results were >140mmHg or >90 respectively and as hypervolemic if their total body water (TBW) was greater than normal according to the Kushner formula+1SD. Vasoconstriction was defined as total peripheral resistance index (TPRI) greater than 3000 dyn*sec/cm5*m2. RESULTS: Of 144 hemodialysis patients, 81 (56%) were male; mean age was 67.3±12.1 years and 67 (47%) had hypertension. Among the hypertensive patients, only 18(27%) met hypervolemia criteria and thirty (45%) met vasoconstriction criteria (mean TPRI of 4474±1592dyn*sec/cm5*m2). Patients with hypertension due to vasoconstriction had higher vintage (50±45 vs 20±8 months 0=0.018), lower heart rate (71±11 vs 79±11 BPM p=0.002), lower stroke index (28±7 vs 44±8ml/m2 p<0.001) and cardiac index (2.1±0.5 vs 3.5±0.6 p=0<0.001) compared to patients without vasoconstriction. CONCLUSIONS: Vasoconstriction was the main etiology for pre-dialysis hypertension in chronic hemodialysis patients. This calls for individualized, hemodynamic-based therapeutic intervention.

INTRODUCTION: Atrial fibrillation (AF) is a major increasing public health problem worldwide, with clinical and epidemiological differences between men and women. However, contemporary population-level data on incidence and survival are scarce. AIM: To evaluate sex-specific contemporary trends in the incidence, prevalence, and long-term survival of non-valvular AF in a real-world setting. METHODS: AF patients diagnosed between 2007-2015, insured by a large, state-mandated health organization in Israel (Maccabi Healthcare Services) were included. AF was diagnosed based on registered diagnoses. Patients with valvular disease, active malignancy, cardiac surgery ≤ 6 months, or recent pregnancy, were excluded. Annual incidence rate, period prevalence, and 5-year survival for each calendar year during the study period, were calculated. RESULTS: A total of 15,409 eligible patients (8,288 males, 7,121 females) were identified. Males were more likely to be younger, have higher rates of underlying diseases (ischemic heart disease, heart failure, and chronic obstructive pulmonary disease), but with lower rates of hypertension and chronic kidney diseases as compared to female patients. During the study period, age-adjusted incidence decreased both in men: (-0.020/1,000-person year, p-for trend = 0.033) and, women (-0.025/1,000 person-year p = 0.009). The five-year survival rate was significantly higher among men vs. women (77.1% vs. 71.5%, respectively, p<0.001). Age-adjusted prevalence increased significantly among men (+0.102 per year, p-for trend<0.001) yet decreased among women (-0.082 per year, p-for trend = 0.005). A significant trend toward improved long-term survival was observed in women and not in men. CONCLUSIONS: The current study shows significant sex-related disparities in the incidence, prevalence, and survival of AF patients between 2007-2015; while the adjusted incidence of both has decreased over-time, prevalence and mortality decreased significantly only in women.

Background Shortening the pain-to-balloon (P2B) and door-to-balloon (D2B) intervals in patients with ST-segment-elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PPCI) is essential in order to limit myocardial damage. We investigated whether direct admission of PPCI-treated patients with STEMI to the catheterization laboratory, bypassing the emergency department, expedites reperfusion and improves prognosis. Methods and Results Consecutive PPCI-treated patients with STEMI included in the ACSIS (Acute Coronary Syndrome in Israel Survey), a prospective nationwide multicenter registry, were divided into patients admitted directly or via the emergency department. The impact of the P2B and D2B intervals on mortality was compared between groups by logistic regression and propensity score matching. Of the 4839 PPCI-treated patients with STEMI, 1174 were admitted directly and 3665 via the emergency department. Respective median P2B and D2B were shorter among the directly admitted patients with STEMI (160 and 35 minutes) compared with those admitted via the emergency department (210 and 75 minutes, P<0.001). Decreased mortality was observed with direct admission at 1 and 2 years and at the end of follow-up (median 6.4 years, P<0.001). Survival advantage persisted after adjustment by logistic regression and propensity matching. P2B, but not D2B, impacted survival (P<0.001). Conclusions Direct admission of PPCI-treated patients with STEMI decreased mortality by shortening P2B and D2B intervals considerably. However, P2B, but not D2B, impacted mortality. It seems that the D2B interval has reached its limit of effect. Thus, all efforts should be extended to shorten P2B by educating the public to activate early the emergency medical services to bypass the emergency department and allow timely PPCI for the best outcome.

BACKGROUND: Efforts to mitigate the risk for perioperative cardiac events focus on both patient's and operation's risk and often include a preprocedural electrocardiogram (ECG). The merits of postprocedural ECG for detection of occult cardiac events occurring during surgery are unknown. We aim to explore the incidence of pre, and new postprocedural ECG pathologies in an intermediate-high risk population undergoing non-cardiac surgery. METHODS: This single-center, prospective, observational study, included patients older than 18 years with at least two cardiovascular risk factors who were scheduled for non-cardiac surgery. All patients had pre, and postprocedural ECG. The ECG was analyzed and coded according to the Minnesota criteria. A multivariable logistic regression analysis was performed for indices associated with new postoperative ECG pathologies. RESULTS: A total of 217 patients were enrolled. Preoperative pathologic ECG changes were recorded in 62.2% of the patients. Postoperatively, new ECG pathologies were documented in 49.8% of patients, most commonly T-wave changes (36.4% of changes). Pathologic ECG changes at baseline (OR 3.15, 95% CI [1.61-6.17]; P<0.01), diabetes (OR 1.93, 95% CI [1.02-3.64]; P=0.04), history of ischemic heart disease (OR 2.14, 95% CI [1.03-4.47]; P=0.04), higher volumes of fluid replacement (OR 1.70, 95% CI [1.10-2.61]; P=0.01) and higher levels of preoperative hemoglobin (OR 1.24, 95% CI [1.04-1.47]; P=0.01) were all independently associated with postoperative ECG changes. CONCLUSIONS: Pre-, but most importantly, postoperative ECG changes are common in intermediate-high risk surgical patients. Postoperative ECG may be valuable to disclose silent cardiovascular events that occurred during surgery.

INTRODUCTION: Alternation in traditional vital signs can only be observed during advanced stages of hypovolemia and shortly before the hemodynamic collapse. However, even minimal blood loss induces a decrease in the cardiac preload which translates to a decrease in stroke volume, but these indices are not readily monitored. We aimed to determine whether minor hemodynamic alternations induced by controlled and standardized hypovolemia can be detected by a whole-body bio-impedance technology. METHODS: This was a non-randomized controlled trial that enrolled healthy blood donors. Vital signs, as well as shock index and stroke volume (SV), were recorded using noninvasive cardiac system, a noninvasive whole-body impedance-based hemodynamic analysis system, during phlebotomy. RESULTS: Sixty subjects were included in the study group and 20 in the control group. Blood loss of 450 mL resulted in a significant decrease in systolic blood pressure (5 mm Hg; 95% CI 3, 6) and SV (5.07âmL; 95% CI 3.21, 6.92), and increase in shock index (0.03âbpm/mm Hg; 95% CI 0.01, 0.05). Clinically detectable changes (≥10%) in blood pressure and shock index were detectable in 15% and 5%, respectively. SV decreased by more than 10% in 40% of blood donors. No significant changes occurred in the control group. CONCLUSION: Continuous noninvasive monitoring of SV may be superior to conventional indices (e.g., heart rate, blood pressure, or shock index) for early identification of acute blood loss. As an operator-independent and point-of-care technology, the SV whole body bio-impedance measurement may assist in accurate monitoring of potentially bleeding patients and early identification of hemorrhage.

AIMS: Efforts are constantly made to decrease the rates of readmission after acute decompensated heart failure (ADHF). ADHF admissions to internal medicine departments (IMD) were previously associated with higher risk for readmission compared with those admitted to cardiology departments (CD). It is unknown if the earlier still applies after recent advancement in care over the last decade. This contemporary cohort compares characteristics and outcomes of ADHF patients admitted to IMD with those admitted to CD. METHODS AND RESULTS: The data for this single-centre, retrospective study utilized a cohort of 8332 ADHF patients admitted between 2007 and 2017. We compared patients' baseline characteristics and clinical and laboratory indices of patients admitted to CD and IMD with the outcome defined as 30 day readmission rate. In comparison with those admitted to CD, patients admitted to IMD (89.5% of patients) were older (79 [70-86] vs. 69 [60-78] years; P < 0.001) and had a higher incidence of co-morbidities and a higher ejection fraction. Readmission rates at 30 days were significantly lower in patients admitted to CD (15.9% vs. 19.6%; P = 0.01). Conflicting results of three statistical models failed to associate between the admitting department and 30 day readmission (odds ratio for 30 day readmission in CD: forced and backward stepwise logistic regression 0.8, 95% confidence interval 0.65-0.97, P = 0.02; stabilized inverse probability weights model odds ratio 1.0, confidence interval 0.75-1.37, P = 0.96). CONCLUSIONS: This contemporary analysis of ADHF patient cohort demonstrates significant differences in the characteristics and outcomes of patients admitted to IMD and CD. Thus, focusing strategies for readmission prevention in patients admitted to IMD may be beneficial.

COVID-19 outbreak has a profound impact on almost every aspect of life. Universal masking is recommended as a means of source control. Routinely exercising in a safe environment is an important strategy for healthy living during this crisis. As sports clubs and public spaces may serve a source of viral transmission, masking may become an integral part of physical activity. This study aimed to assess the physiological effects of wearing surgical masks and N95 respirators during short-term strenuous workout. This was a multiple cross-over trial of healthy volunteers. Using a standard cycle ergometry ramp protocol, each subject performed a maximal exercise test without a mask, with a surgical mask, and with an N95 respirator. Physiological parameters and time to exhaustion were compared. Each subject served his own control. Sixteen male volunteers (mean age and BMI of 34 ± 4 years and 28.72 ± 3.78 kg/m2 , respectively) completed the protocol. Heart rate, respiratory rate, blood pressure, oxygen saturation, and time to exhaustion did not differ significantly. Exercising with N95 mask was associated with a significant increase in end-tidal carbon dioxide (EtCO2 ) levels. The differences were more prominent as the load increased, reaching 8 mm Hg at exhaustion (none vs N95, P = .001). In conclusion, in healthy subjects, short-term moderate-strenuous aerobic physical activity with a mask is feasible, safe, and associated with only minor changes in physiological parameters, particularly a mild increase in EtCO2 . Subjects suffering from lung diseases should have a cautious evaluation before attempting physical activity with any mask.
