Abstract Background Skeletal scintigraphy with bone tracers is a key tool for cardiac ATTR diagnosis. However its prognostic value has not been systematically assessed. Purpose We evaluated the prognostic relevance of a quantitative method to assess regional 99mTc-DPD uptake by SPECT in the heart of ATTRwt patients. Methods All ATTRwt patients (n=229) undergoing clinical assessment and bone scintigraphy at our center (from 2012 to 2019) were enrolled. Theyreceived approximately 700 MBq of 99mTc-DPD. Planar whole body acquisition 10' after the injection followed by cardiac SPECT after 3 hours were performed. SPECT data were reconstructed into 64x64 matrices with an ordered-subset expectation maximization algorithm. For each wall region and for the apex, a circular region of interest (ROI, 20 pixels) was manually drawn and a value equating to the number of counts contained in the ROI was obtained. Partial correlation of ln-transformed ROI and biomarkers was retrieved from a multivariable regression model, while controlling for each cardiac wall region. Multivariable Cox regression was used to assess the prognostic role of lnROI while adjusting for wall region, NT-proBNP, cTnI and eGFR. Hazard ratios and 95% confidence intervals (HR, 95% CI) were computed. The Harrell's c statistic was reported for model discrimination. The interaction of biomarker and regional wall on survival was assessed; also, to account for intra-subject correlation of measures, within subject robust standard errors were computed. Results Median follow-up was 21 months (IQR 11, 40) and 39 (17%) patients died. Median age was 76 years (IQR, 72–80), NT-proBNP 2944 ng/L (IQR, 1815–5319), cTnI 0.095 ng/L (IQR, 0.062–0.144) and eGFR 62 mL/min (IQR, 51–77). ROI did not correlate with any of NT-proBNP, eGFR, age, cTnI or mLVWT (R<1% in all cases). All analyses were adjusted for cardiac wall. At the multivariable Cox regression (Harrell's c=0.75), there was a linear increase in the risk of death associated with lnROI (HR 2.14, P=0.014), which was independent of cardiac wall region, NTproBNP, cTnI and eGFR. Only cTnI maintained a significant prognostic value. The association of lnROI and mortality was not modified by the site of measurement test for interaction with cardiac wall p=0.818). At the predefined subgroup analysis, the risk of death was similar for all walls; we computed the optimal cut-off for 12 months survival at the apex (a region usually lately involved) to 4193 (AUC: 0.68, sensitivity 80%, specificity 68%). At the multivariable Cox regression (Harrell's c 0.76), apex ROI>4193 was an independent predictor of death (HR 3.60, 95% CI 1.45–8.93, p=0.006) and outperformed all the biomarkers tested. Conclusions Quantitative assessment of ROI uptake at cardiac SPECT is a powerful predictor of survival in ATTRwt patients, independent of and outperforming the other known prognostic factors. This observation warrants validation with prolonged follow-up and in independent patient series. Funding Acknowledgement Type of funding source: None

Background: Myocardial bridging (MB) is frequently seen on coronary CT angiography (CCTA). However, there has been conflicting data on the prognostic value of MB. The aim of this analysis is to determine the prognostic value of MB in patients without obstructive coronary artery disease (CAD) (<50 diameter stenosis). Methods: We included patients with no known prior coronary artery disease (CAD) who underwent CCTA for various clincial reasons. Patients with obstructive CAD on CCTA were excluded. The study cohort was followed for all cause mortality or myocardial infarction (MI) (median follow-up 1.7 years). Group comparisons were made between patients with patients with or without MB. Results: A total of 715 patients were included in this analysis of which 68 patients had MB (10%). 73% of the bridges were in the mid LAD and 22% had bridging in the distal LAD. 48% of the study cohort had normal coronaries, while 52% had evidence of non obstructive CAD. There were no differences in the baseline characteristics, symptomatic status or prevalence of non obstructive CAD between the two groups (all p>0.5). After a median follow-up duration of 1.7 years, 23 patients died and 10 patients experienced myocardial infarction. There were no statistically significant differences in the rate of death/MI between the two groups (figure). Using multivariable Cox regression, the presence of MB was not associated with increased risk for death/MI (Adjusted HR 0.4, 95% confidence interval 0.1 -2.8, p=0.34) Conclusions: In patients with non-obstructive CAD, MB is not associated with increased risk for all cause death or MI.

Abstract Background Associations between D-dimer and outcomes of patients with acute coronary syndromes (ACS) remain controversial. This study aimed to investigate the prognostic value of D-dimer in ACS patients treated by percutaneous coronary intervention (PCI). Methods In this observational study, 3972 consecutive patients with ACS treated by PCI were retrospectively recruited. The X-tile program was used to determine the optimal D-dimer thresholds for risk stratifications. Cox regression with multiple adjustments was used for outcome analysis. Restricted cubic spline (RCS) analysis was performed to assess the dose-response association between D-dimer and outcomes. The C-index was calculated to evaluate the additional prognostic value of D-dimer when added to clinical risk factors and commonly used clinical risk scores, with internal validations using bootstrapping methods. The primary outcome was all-cause death. Results During a median follow-up of 720 days, 225 deaths occurred. Based on the thresholds generated by X-tile, ACS-PCI patients with median (420–1150 ng/mL, hazard ratio [HR]: 1.58, 95 % confidence interval [CI]: 1.14–2.20, P = 0.007) and high (≥ 1150 ng/mL, HR: 1.98, 95 % CI: 1.36–2.89, P < 0.001) levels of D-dimer showed substantially higher risk of death compared to those with low D-dimer (< 420 ng/mL). RCS analysis depicted a constant relation between D-dimer and various outcomes. The addition of D-dimer levels significantly improved risk predictions for all-cause death when combined with the fully adjusted models (C-index: 0.853 vs. 0.845, P difference = 0.021), the GRACE score (C-index: 0.826 vs. 0.814, P difference = 0.027), and the TIMI score (C-index: 0.804 vs. 0.776, P difference < 0.001). The predicted mortality at the median follow-up (two years) was 1.7 %, 5.2 %, and 10.9 % for patients with low, median, and high D-dimer, respectively, which was well matched with the observed mortality (low D-dimer group: 1.2 %, median D-dimer group: 5.2 %, and high D-dimer group: 12.6 %). Conclusions For ACS patients treated by PCI, D-dimer level was an independent predictor for adverse outcomes, and provided additional prognostic value when combined with clinical risk factors and risk scores. Risk stratifications based on D-dimer was plausible to differentiate ACS-PCI patients with higher risk of death.

Abstract Background Global longitudinal strain (GLS) demonstrated a superior prognostic value over left ventricular ejection fraction (LVEF) in acute heart failure (HF). Its prognostic value across American Heart Association (AHA) stages of HF – especially under considering of conventional echocardiographic measures of systolic and diastolic function – has not yet been comprehensively evaluated. Purpose To evaluate the prognostic value of GLS for HF-specific outcome across AHA HF stages A to D. Methods Data from the MyoVasc-Study (n=3,289) were analysed. Comprehensive clinical phenotyping was performed during a five-hour investigation in a dedicated study centre. GLS was measured offline utilizing QLab 9.0.1 (PHILIPS, Germany) in participants presenting with sinus rhythm during echocardiography. Worsening of HF (comprising transition from asymptomatic to symptomatic HF, HF hospitalization, and cardiac death) was assessed during a structured follow-up with subsequent validation and adjudication of endpoints. AHA stages were defined according to current guidelines. Results Complete information on GLS was available in 2,400 participants of whom 2,186 categorized to AHA stage A to D were available for analysis. Overall, 434 individuals were classified as AHA stage A, 629 as stage B and 1,123 as stage C/D. Mean GLS increased across AHA stages of HF: it was lowest in stage A (−19.44±3.15%), −18.01±3.46% in stage B and highest in AHA stage C/D (−15.52±4.64%, P for trend &lt;0.0001). During a follow-up period of 3.0 [1.3/4.0] years, GLS denoted an increased risk for worsening of HF after adjustment for age and sex (hazard ratio, HRGLS [per standard deviation (SD)] 1.97 [95% confidence interval 1.73/2.23], P&lt;0.0001) in multivariable Cox regression analysis. After additional adjustment for cardiovascular risk factors, clinical profile, LVEF and E/E' ratio, GLS was the strongest echocardiographic predictor of worsening of HF (HRGLS [per SD] 1.47 [1.20/1.80], P=0.0002) in comparison to LVEF (HRLVEF [per SD] 1.23 [1.02/1.48], P=0.031) and E/E' ratio (HRE/E' [per SD] 1.12 [0.99/1.26], P=0.083). Interestingly, when stratifying for AHA stages, GLS denoted a similar increased risk for worsening of HF in individuals classified as AHA stage A/B (HRGLS [per SD] 1.63 [1.02/2.61], P=0.039) and in those classified as AHA stage C/D (HRGLS [per SD] 1.95 [1.65/2.29], P&lt;0.0001) after adjustment for age and sex. For further evaluation, Cox regression models with interaction analysis indicated no significant interaction for (i) AHA stage A/B vs C/D (P=0.83) and (ii) NYHA functional class &lt;II vs ≥II in individuals classified as AHA stage C/D (P=0.12). Conclusions GLS demonstrated a higher predictive value for worsening of HF than conventional echocardiographic measures of systolic and diastolic function. Interestingly, GLS indicated an increased risk for worsening of HF across AHA stages highlighting its potential value to advance risk prediction in chronic HF.

ObjectiveTo determine the prevalence and prognostic value of weight loss (WL) prior to diagnosis in patients with amyotrophic lateral sclerosis (ALS).MethodsWe enrolled patients diagnosed with ALS between 2010 and 2018 in a population-based setting. At diagnosis, detailed information was obtained regarding the patient’s disease characteristics, anthropological changes, ALS-related genotypes and cognitive functioning. Complete survival data were obtained. Cox proportional hazard models were used to assess the association between WL and the risk of death during follow-up.ResultsThe data set comprised 2420 patients of whom 67.5% reported WL at diagnosis. WL occurred in 71.8% of the bulbar-onset and in 64.2% of the spinal-onset patients; the mean loss of body weight was 6.9% (95% CI 6.8 to 6.9) and 5.5% (95% CI 5.5 to 5.6), respectively (p<0.001). WL occurred in 35.1% of the patients without any symptom of dysphagia. WL is a strong independent predictor of survival, with a dose response relationship between the amount of WL and the risk of death: the risk of death during follow-up increased by 23% for every 10% increase in WL relative to body weight (HR 1.23, 95% CI 1.13 to 1.51, p<0.001).ConclusionsThis population-based study shows that two-thirds of the patients with ALS have WL at diagnosis, which also occurs independent of dysphagia, and is related to survival. Our results suggest that WL is a multifactorial process that may differ from patient to patient. Gaining further insight in its underlying factors could prove essential for future therapeutic measures.

The Impact

Cholinesterase inhibitors (ChEIs) are the mainstays of symptomatic treatment of Alzheimer’s disease (AD); however, their efficacy is limited, and their use was associated with deaths in some groups of patients. The aim of the current study was to assess the impact of the long-term use of ChEIs on mortality in patients with AD. This observational, longitudinal study included 1171 adult patients with a diagnosis of AD treated with donepezil or rivastigmine. Each patient was observed for 24 months or until death. The cognitive and functional assessments, the use of ChEIs, memantine, antipsychotics, antidepressants, and anxiolytics were recorded. The total number of deaths at the end of the observational period was 99 (8.45%). The patients who had received rivastigmine treatment were at an increased risk of death in the follow-up period. The higher risk of death in the rivastigmine group remained significant in multivariate Cox regression models.

The aims were to prospectively assess the mortality risk following proximal hip fractures, identify factors predictive of increased mortality and to investigate the time trends in mortality with comparison to previous studies. Prospectively collected data from 68 consecutive patients who had been admitted to a regional hospital from May 2001 to September 2001 were reviewed. The mean age of the patients was 79.3 years old (range, 55–98) and 72.1% females. Patients were followed prospectively to determine the mortality risk associated with hip fracture over a two-year follow-up period. The acute in-hospital mortality rate at six months, one year and two years was 5.9% (4/68), 14.7% (10/68), 20.6% (14/68) and 25% (17/68) respectively. One-year and two-year mortality for those patients who were 80 or older was significantly higher than for other patients and the number of co-morbid illnesses also had significant effect. Cox regression was performed to determine the significant predictors for survival time. It was noted that patients 80 years or older were at higher risk of death compared with those less than 80 years as well as those with higher number of co-morbid illnesses. Our mortality rates have not declined in the past 10 years when compared with previous local studies. We conclude that for this group of patients studied, their mortality at one year and two years could be predicted by their age group and their number of co-morbid illnesses.

AbstractBackground:As epidemiological studies have become more complex, demands for short, easily administered measures of risk factors have increased. This study investigates whether such a measure of physical activity is associated with the risk of death from all causes and death from specific causes.Methods:A prospective follow-up study of 11 090 men and women, aged 35–64 years, recruited from five UK general practices who responded to a postal questionnaire in 1989. Self-reported frequency of vigorous-intensity physical activity and data on confounding factors were collected at baseline survey. Death notifications up to 31 December 2001 were provided by the Office for National Statistics. The relative risk (and 95% confidence interval) of dying associated with each level of exposure to physical activity was estimated by the hazard ratio in a series of Cox regression models.Results:After > 10 years' follow-up there were 825 deaths among the 10 522 subjects with no previous history of angina or myocardial infarction. Participation in vigorous exercise was associated with a significantly lower risk of all-cause mortality. Similar associations were found for ischaemic heart disease and cancer mortality, although the relationships were not significant at the 5% level.Conclusions:Simple measures of self-reported vigorous physical activity are associated with the risk of future mortality, at least all-cause mortality in a somewhat selected group. Interpretation of the finding should be treated with caution due to the reliance on self-report and the possibility that residual confounding may underlie the associations. Because moderate-intensity physical activity is also beneficial to health, short physical activity questionnaires should include measures of such physical activity in the future.

SummaryBackground:Since serial analyses of NT-proBNP in patients with acute coronary syndromes have shown that levels measured during a chronic, later phase are a better predictor of prognosis and indicator of left ventricular function than the levels measured during an acute phase, we sought to assess the association of NT-proBNP, measured 6 months after acute myocardial infarction (AMI), with traditional risk factors, characteristics of in-hospital and early postinfarction course, as well as its prognostic value and optimal cut-points in the ensuing 1-year follow-up.Methods:Fasting venous blood samples were drawn from 100 ambulatory patients and NT-proBNP concentrations in lithium-heparin plasma were determined using a one-step enzyme immunoassay based on the »sandwich« principle on a Dimension RxL clinical chemistry system (DADE Behring-Siemens). Patients were followed-up for the next 1 year, for the occurrence of new cardiac events.Results:Median (IQR) level of NT-proBNP was 521 (335–1095) pg/mL. Highest values were mostly associated with cardiac events during the first 6 months after AMI. Negative association with reperfusion therapy for index infarction confirmed its long-term beneficial effect. In the next one-year follow-up of stable patients, multivariate Cox regression analysis revealed the independent prognostic value of NT-proBNP for new-onset heart failure prediction (p=0.014), as well as for new coronary events prediction (p=0.035). Calculation of the AUCs revealed the optimal NT-proBNP cut-points of 800 pg/mL and 516 pg/mL, respectively.Conclusions:NT-proBNP values 6 months after AMI are mainly associated with the characteristics of early infarction and postinfarction course and can predict new cardiac events in the next one-year follow-up.

Background: Brain metastases are a frequently occurring and devastating complication of solid organ malignancies. Individuals with brain metastases are noted to be high risk for venous thromboembolism (VTE) due to hypercoagulability from their malignancy, immobility, and need for cancer directed therapies. The management of VTE in patients with brain metastases is challenging due to the risk of intracranial hemorrhage (ICH) with therapeutic anticoagulation. Inferior vena cava filter (IVCF) are often used to mitigate the risk of ICH, however the utility of this practice and the impact on survival is not clear. Methods: We performed a retrospective cohort study using the linked California Cancer Registry (CCR) and California Patient Discharge Database (PDD) between 2005-2017 with follow up available to 2018. We identified individuals with breast and lung cancer (because they are common), and renal cell carcinoma and melanoma (because of bleeding tendency of brain metastases) who had an incident hospitalization with VTE (either pulmonary embolism, deep vein thrombosis or both). Brain metastasis were identified using the presence of International Classification of Diseases, 9th Edition, Clinical Modification (ICD-9-CM) code 198.3 or ICD-10-CM code C79.31 present anytime in PDD and cases were classified as having brain metastases if the code was present prior to or at the time of the index VTE. Cases with multiple malignancies were excluded. ICD-9-CM code 38.7 and ICD-10-CM code 02HV was used to identify patients who received an IVCF. Univariate analysis was used to determine differences in baseline characteristics between those that did and did not receive an IVCF. A logistic regression model that included patient and index VTE hospital characteristics was used to develop a propensity score for IVCF placement. The primary outcomes were 30-day mortality and 180-day intracranial hemorrhage (ICH) determined by ICD codes. A Cox proportional hazards model, inverse propensity weighted for IVCF placement, was used to assess the effect of IVCF placement (as a time-dependent variable) on 30-day mortality. The effect of IVCF on ICH was assessed with a 1:3 propensity matched Fine-Gray model, accounting for the competing risk of death. Results: There were 17,182 patients with a diagnosis of VTE present on admission and an active first primary cancer diagnosis of interest, of these 3,309 (19.3%) had a diagnosis of brain metastasis with median follow-up of 96.8 months. The baseline characteristics of patients are summarized in Table 1. Among patients with brain metastases, 757 of 3309 (22.9%) had an IVCF inserted versus 1801 of 13873 (13.0%) in those without brain metastases (p&lt;0.001). In a multivariable logistic regression model the presence of brain metastasis was an independent predictor for the placement of IVCF (Odds Ratio (OR) 1.84 (95% CI 1.64-2.05). Using balanced (standardized mean difference less than 0.1 for all covariates included in the model) IPW-adjusted Cox regression model, the use of IVCF did not reduce the 30-day risk of death in those with acute VTE (Hazard Ratio (HR) 1.08 (95% CI 0.95-1.23). The presence of brain metastases was associated with a higher 30-day risk of death (HR 1.23 (95% CI 1.13- 1.35). Using IPW-adjusted Cox model restricted to those with brain metastasis, IVCF use was associated with a trend towards reduced 30-day risk of death (HR 0.86 (95% CI 0.73-1.01). In a propensity matched Cox regression competing risk model, the presence of brain metastases was significantly associated with an increased 180-day risk of ICH (HR 6.91 (95% CI 3.54-13.48), with no difference for those that received an IVCF (HR 1.31 (95% CI 0.85-2.01). When compared to breast cancer patients, those with lung cancer had lower risk of ICH (HR 0.28, CI 0.13-0.64), but melanoma and renal cell cancer did not have higher risk. Conclusions: This real-world retrospective population-based study demonstrated the use of IVCF was higher for patients with brain metastases among these four tumor types. There was a suggestion of reduced short-term mortality associated with IVCF placement in VTE patients and brain metastases, but this was not statistically significant. Although limited by the lack of data on anticoagulation use, there was no effect of IVCF placement on the risk of ICH. Randomized clinical trials are needed to determine the effect of IVCF on clinically relevant outcomes for VTE in patients with brain metastasis.

Abstract Introduction Contemporary guidelines recommend a universal cutoff of 14 for the ratio between early mitral flow wave and early diastolic mitral annulus velocity measured by tissue doppler (E/e' ratio). While age-dependent normal E/e' values have been suggested, outcome data is lacking. Purpose We sought to evaluate the modification effect of age and gender on the prognostic value of the E/e' ratio. Methods Consecutive patients who underwent echocardiographic evaluation between 2009 and 2021 (N=104,315) in a single tertiary cardiovascular center. Patients with left or right ventricular dysfunction, any significant valvular disease, structural heart disease or evidence of pulmonary hypertension were excluded. Cancer and mortality data were available for all subjects from national registries. Patients with a metastatic malignancy at baseline or during follow up were excluded. Cox regression models were applied. Results Overall, 44,541 patients were included in the final analysis. Mean age was 55±17, 59% were male and 63% of the exams were performed in an outpatient setting. An elevated E/e' ratio above 14 was documented in 2,598 (7%) patients. During a median follow-up of 5.7 (IQR 2.8–9.1) years, 5,015 (11.3%) patients died. Kaplan Meier survival analysis demonstrated that the cumulative probability of death at 6 years was 23.4% (21.6–25.3) among patients with elevated E/e' ratio compared with 9.7% (9.3–10.0) among patients with E/e'&lt;14 (p Log rank &lt;0.001). This difference was less significant as age progressed (figure 1). Multivariate cox-regression model yielded consistent results such that an elevated E/e' ratio was associated with 2.66-fold increased risk of death during follow up (95% CI 2.44–2.89, p&lt;0.001), and there was a decline in the increased risk and significant as age advanced in both genders (figure 2). Interaction analysis was significant for both gender and age such the association of elevated E/e' ratio with poor survival was more significant among men compared with women and among young vs. older subjects. Among women, elevated E/e' was associated with 2.4-fold increased risk of death versus 2.7-fold increased risk among men. Similarly, the hazard ratio for death associated with elevated E/e' was 2.29 (95% CI 1.74–3.02), 1.8 (95% CI 1.5–2.1), 1.13 (95% CI 0.97–1.31) and 1.07 (95% CI 0.92–1.25) for the age groups of &lt;60, 60–70, 70–80 and &gt;80, respectively. In a sensitivity analysis, similar findings were seen in when excluding patients with mild hypertrophy (maximal wall thickness &gt;12mm) and without any mitral annulus calcification. Conclusion In apparently normal hearts, an elevated E/e' ratio is independently associated with increased mortality. This association is more pronounced among men and is attenuated with increased age. This study supports the need for gender-specific and age-specified outcome data with respect to measures of diastolic dysfunction. FUNDunding Acknowledgement Type of funding sources: None.
