Iso-osmolar vs low-osmolar contrast agents for coronary optical coherence tomography: a blinded prospective randomized controlled study.

The impact of contrast type on coronary optical coherence tomography (OCT) imaging has received limited research. We conducted a blinded, prospective, single-center, randomized, controlled crossover study comparing iso-osmolar contrast media (IOCM) with low-osmolar contrast media (LOCM) in patients undergoing clinically indicated coronary OCT imaging. Patients were randomly assigned to undergo OCT imaging with either IOCM or LOCM as the initial contrast medium. Following a washout period, a second run of OCT imaging of the same coronary vessel was performed using the other contrast medium. A total of 62 patients were randomized to IOCM first (n = 31) or LOCM first (n = 31). Mean patient age was 65.9 ± 11.2 years and 74.2% were male, with high prevalence of dyslipidemia (82.3%) and prior myocardial infarction (41.9%). Percutaneous coronary intervention was performed in 60 cases (96.8%) and the left anterior descending artery was the most common target vessel (53.3%). The contrast volume used for OCT imaging was similar for IOCM and LOCM (8.0 [6.9, 9.0] mL vs 8.0 [6.7, 9.0] mL; P = .89), as was the length of clear OCT images (70.0 [62.8, 74.0] mm for IOCM vs 70.0 [64.0, 74.0] mm for LOCM; P = .65). Electrocardiographic changes were observed in 11 runs with IOCM (ventricular repolarization changes in 9 runs and premature ventricular contractions [PVCs] in 2 runs) vs 12 runs with LOCM (ventricular repolarization changes in 9 runs and PVCs in 3 runs). The use of IOCM in coronary OCT is associated with similar contrast volume and clear imaging length when compared with LOCM.

Comparison of successful versus failed percutaneous coronary intervention in patients with chronic total occlusion: A systematic review and meta-analysis.

The optimal treatment strategy of chronic total occlusion (CTO) is currently debated. This meta-analysis aimed to evaluate the long-term clinical outcomes of successful percutaneous coronary intervention (PCI) of CTO. Electronic databases were searched for studies comparing long-term outcomes between successful PCI in patients with CTO using drug-eluting stents and failed procedures. Meta-analysis was conducted with major adverse cardiac events (MACE) and all-cause mortality during the longest follow-up as endpoints. The combined hazard ratios (HRs) were applied to assess the correlation between successful CTO PCI and MACE/all-cause mortality. Eight studies consisting of 6,211 patients published between 2012 and 2020 met our inclusion criteria, and the CTO PCI success rate was 81.2%. Patients in the failed group were much older, and more likely to have morbidities (hypertension and prior myocardial infarction), reduced left ventricular ejection fraction, and severe lesion characteristics (multivessel disease and moderate/severe calcification). Pooled results indicated that successful CTO PCI was significantly associated with prognosis. Compared to failed recanalization, patients receiving successful procedures had an improved MACE (HR: 0.50, 95% CI: 0.40-0.61, p < 0.001). Subgroup analyses further revealed the prognostic value of successful CTO PCI. However, no difference was observed regarding all-cause mortality (HR: 0.79, 95% CI: 0.61-1.02, p = 0.074). The present study showed that CTO recanalization was associated with improved long-term outcomes. However, randomized trials are needed to confirm the results due to the mismatch of baseline characteristics.

Cardiovascular Eligibility Criteria and Adverse Event Reporting in Combined Immune Checkpoint and VEGF Inhibitor Trials

BackgroundCombination therapy with immune checkpoint inhibitors (ICIs) and vascular endothelial growth factor inhibitors (VEGFIs) has improved cancer outcomes and is increasingly used. These drug classes are associated with cardiovascular toxicities when used alone, but heterogeneity in trial design and reporting may limit knowledge of toxicities in patients receiving these in combination. ObjectivesThe aim of this study was to assess consistency and clarity in definitions and reporting of cardiovascular eligibility criteria, baseline characteristics, and cardiovascular adverse events in ICI and VEGFI combination trials. MethodsA scoping review was conducted of phase 2 to 4 randomized controlled trials of ICI and VEGFI combination therapy for solid tumors. Trial cardiovascular eligibility criteria and baseline cardiovascular characteristic reporting in trial publications was assessed, and cardiovascular adverse event definitions and reporting criteria were also examined. ResultsSeventeen trials (N = 10,313; published 2018-2022) were included. There were multiple cardiovascular exclusion criteria in 15 trials. No primary trial publication reported baseline cardiovascular characteristics. Thirteen trials excluded patients with prior heart failure, myocardial infarction, hypertension, or stroke. There was heterogeneity in defining cardiovascular conditions. “Grade 1 to 4” cardiovascular adverse events were reported when incidence was ≥5% to 25% in 15 trials. Incident hypertension was recorded in all trials, but other cardiovascular events were not consistently reported. No trial specifically noted the absence of cardiovascular events. ConclusionsIn ICI and VEGFI combination trials, there is heterogeneity in cardiovascular exclusion criteria, reporting of baseline characteristics, and reporting of cardiovascular adverse events. This limits an optimal understanding of the incidence and severity of events relating to these combinations. Better standardization of these elements should be pursued.

Statin use and mortality in patients with deep vein thrombosis. Data from the RIETE Registry

BackgroundThe association between statin use and mortality in patients with deep vein thrombosis (DVT) has not been rigorously evaluated. MethodsWe used the data in the RIETE registry to examine the association between statin use and mortality at 3 months. We used mixed effects survival models accounting for clinical covariates and clustering of patients in enrolling centers. ResultsFrom January 2009 through April 2022, there were 46,440 patients with isolated DVT in RIETE (in the lower-limbs 42,291, in the upper limbs 4149). Of these, 21 % and 18 %, respectively, were using statins. Statin users were older than non-users (72 ± 12 vs. 62 ± 18 years), and more likely had diabetes, hypertension, prior myocardial infarction or ischemic stroke, or were receiving antiplatelets. The 3-month mortality rates were: 6.0 % vs. 5.8 %, respectively. On multilevel multivariable analysis, the adjusted hazard ratio (aHR) for all-cause death in statin users vs. non-users was 0.77 (95%CI: 0.69–0.86). The 3-month risk of death in statin users was significantly lower than in non-users in patients with upper-limb DVT (aHR: 0.81; 95%CI: 0.72–0.91), distal lower-limb DVT (aHR: 0.48; 95%CI: 0.32–0.72), or proximal lower-limb DVT (aHR: 0.69; 95%CI: 0.50–0.95), and in those receiving simvastatin (aHR: 0.73; 95%CI: 0.60–0.90), atorvastatin (aHR: 0.70; 95%CI: 0.59–0.85), or rosuvastatin (aHR: 0.47; 95%CI: 0.27–0.80). Major bleeding, used as a falsification endpoint, did not show an association with use of statins at 3-month follow-up. ConclusionsStatin users with isolated DVT were at significantly lower risk for death at 3 months than non-users.

Performance of the European Society of Cardiology 0/1-hour algorithm with high-sensitivity cardiac troponin T at 90 days among patients with known coronary artery disease

BackgroundThe European Society of Cardiology (ESC) 0/1-h high sensitivity troponin T (hs-cTnT) algorithm does not differentiate risk based on known coronary artery disease (CAD: prior myocardial infarction [MI], coronary revascularization, or ≥ 70% coronary stenosis). We recently evaluated its performance among patients with known CAD at 30-days, but little is known about its longer-term risk prediction. The objective of this study is to determine and compare the performance of the algorithm at 90-days among patients with and without known CAD. MethodsWe performed a pre-planned subgroup analysis of the STOP-CP cohort, which prospectively enrolled ED patients ≥21 years old with symptoms suggestive of ACS without ST-elevation on initial ECG across 8 US sites (1/25/2017–9/6/2018). Participants with 0- and 1-h hs-cTnT measures (Roche, Basel, Switzerland) were stratified into rule-out, observe, and rule-in groups using the ESC 0/1-h algorithm. Algorithm performance was tested among patients with or without known CAD, as determined by the treating provider. The primary outcome was cardiac death or MI at 90-days. Fisher's exact tests were used to compare 90-day event and rule-out rates between patients with and without known CAD. Negative predictive values (NPVs) for 90-day cardiac death or MI with exact 95% confidence intervals were calculated and compared using Fisher's exact test. ResultsThe STOP-CP study accrued 1430 patients, of which 31.4% (449/1430) had known CAD. Cardiac death or MI at 90 days was more common in patients with known CAD than in those without [21.2% (95/449) vs. 10.0% (98/981); p < 0.001]. Using the ESC 0/1-h algorithm, 39.6% (178/449) of patients with known CAD and 66.1% (648/981) of patients without known CAD were ruled-out (p < 0.001). Among rule-out patients, 90-day cardiac death or MI occurred in 3.4% (6/178) of patients with known CAD and 1.2% (8/648) without known CAD (p = 0.09). NPV for 90-day cardiac death or MI was 96.6% (95%CI 92.8–98.8) among patients with known CAD and 98.8% (95%CI 97.6–99.5) in patients without known CAD (p = 0.09). ConclusionPatients with known CAD who were ruled-out using the ESC 0/1-h hs-cTnT algorithm had a high rate of missed 90-day cardiac events, suggesting that the ESC 0/1-h hs-cTnT algorithm may not be safe for use among patients with known CAD.

Correlation of Plasmatic Amyloid Beta Peptides (Aβ-40, Aβ-42) with Myocardial Injury and Inflammatory Biomarkers in Acute Coronary Syndrome.

Background/Objective: Amyloid beta (β) -40 levels increase with age and inflammation states and appear to be associated with clinical manifestations of acute coronary syndrome (ACS). We investigated the correlation of Aβ peptides with myocardial injury and inflammation biomarkers in patients with or without ST elevation myocardial infarction (STEMI, NSTEMI). Methods: This singe-center, cross-sectional, observational, and correlation study included 65 patients with ACS (n = 34 STEMI, 29 males, age = 58 ± 12 years; n = 31 NSTEMI, 22 males, age = 60 ± 12 years) who were enrolled in the coronary care unit within 12 h after symptom onset from February 2022 to May 2023. Aβ peptide levels and biochemical parameters were assessed. Results: NSTEMI patients had a higher prevalence of hypertension (p = 0.039), diabetes (p = 0.043), smoking (p = 0.003), and prior myocardial infarction (p = 0.010) compared to STEMI patients. We observed a higher level of Aβ-42 in NSTEMI (p = 0.001) but no difference in Aβ-40 levels. We also found a correlation between age and NT-proBNP with both Aβ peptides (Aβ-40, Aβ-42) (p = 0.001, p = 0.002 respectively). Conclusions: Our results show that patients with NSTEMI had a higher prevalence of cardiovascular risk factors (hypertension, diabetes, smoking, and prior myocardial infarction). Considering these results, we propose that Aβ-42 can add value to risk stratification in NSTEMI patients.

Abstract 13: Prior Bariatric Surgery is Associated With Reduced Risk of Recurrent Stroke Among Elderly Obese Stroke Survivors: A National Inpatient Sample Study (2016-2019)

Introduction: The paucity of large-scale data exploring the effect of prior bariatric surgery on recurrent stroke outcomes in elderly obese stroke survivors led us to address the gap, with an emphasis on the risk of recurrent stroke and its trends. Methods: A retrospective study was conducted using National Inpatient Sample data from 2016-2019. Elderly obese stroke survivors (&gt; 65 years) having a recurrent acute ischemic stroke (AIS), with or without prior bariatric surgery (PBS), were identified using ICD-10 codes. We compared recurrent stroke trends, demographic characteristics, and comorbidities between the cohorts, employing multivariable and other statistical analyses. Results: The study included 643,505 elderly obese stroke survivors, of which 1.8% (11,820) had PBS. Both groups (PBS vs. no PBS) were predominantly female (59.7% vs. 73.7%), identified as white (76.5% vs. 83.8%), and covered by Medicare (91.7% vs. 90.7%). Despite being the most prevalent comorbidity, hypertension (83.6% vs. 83.2%) was not significantly associated with bariatric surgery status, followed by hyperlipidemia (68.2% vs. 61.6%), diabetes mellitus (60% vs. 52.2%), tobacco use (37.5% vs. 36.4%), prior myocardial infarction (12.8% vs. 15.7%), peripheral vascular disease (8.8% vs. 11.9%), valvular disease (3.9% vs. 3.5%), and drug abuse (1.6% vs. 1.1%). Between 2016 and 2019, recurrent AIS decreased in the PBS group (from 4% to 2.9%, p=0.035) whilst remaining stable in the other group (4.4% to 4.2%, p=0.064). The PBS group exhibited a significantly lower adjusted odds ratio for recurrent AIS (aOR: 0.77, 95% CI: 0.60 - 0.98). Conclusion: Prior bariatric surgery in elderly obese stroke survivors was associated with a 23% lower risk of recurrent AIS and a decreasing trend of AIS recurrence over time. These findings could influence clinical practice and contribute to developing secondary prevention strategies for recurrent stroke among these patients.

Relationship between resting heart rate and long-term outcomes in stabilized patients with myocardial infarction: A prospective community-based cohort study

BackgroundResting heart rate (RHR) during hospitalization has been shown to be associated with adverse outcomes in patients with myocardial infarction (MI). This study aimed to evaluate the long-term prognostic effect of RHR during the stable phase after MI in post-MI patients. MethodsPatients who had prior or new-onset MI and RHR measurements during the stable period after MI between 2006 and 2018 in the community-based Kailuan Study were enrolled. RHR was divided into four groups based on quartiles. Cox regression analysis was used to analyze the association of RHR with primary composite outcome of all-cause death, hospitalization for heart failure (HF), stroke, and recurrent MI and its components. ResultsA total of 4447 post-MI patients were included. During a median follow-up of 7.5 years, 1813 patients (40.8%) developed primary outcomes. Compared to RHR ≤67 bpm, patients with 72 < RHR ≤80 bpm and RHR >80 bpm had increased risks of primary outcome, with adjusted hazard ratios (95% confidence intervals) of 1.23 (1.08–1.40) and 1.35 (1.18–1.55), respectively. The risk of primary outcome increased by 12% (1.07–1.17) for each 10-bpm increase in RHR. Similar results were observed in all-cause death and hospitalization for HF. Restricted cubic splines revealed a linear relationship between RHR and primary outcome, all-cause death, and hospitalization for HF (P for nonlinearity >0.05). ConclusionsRHR during the stable phase after MI was an independent predictor for primary outcome and all-cause death in post-MI patients, and RHR >72 bpm was associated with increased risk for primary outcome and all-cause death.

Navigating Heart Failure: Unveiling Sex Disparities in Guideline-Directed Medical Therapy Combinations

Major heart failure (HF) trials remain insufficient in terms of assessing the differences in clinical characteristics, biomarkers, treatment efficacy, and safety because of the under-representation of women. The study aimed to present sex-related disparities in HF management, including differences in demographics, co-morbidities, cardiac biomarkers, prescribed medications, and treatment outcomes. The study utilized anonymized data from the Turkish Ministry of Health's National Electronic Database between January 1, 2016, and December 31, 2022. The cohort analysis included 2,501,231 adult patients with HF. Specific therapeutic combinations were analyzed using a Cox regression model to obtain relative risk reduction for all-cause death. The primary end point was all-cause mortality. In the cohort, 48.7% (n = 1,218,911) were male, whereas 51.3% (n = 1,282,320) were female. Female patients exhibited a higher median age (71 vs 68 years) and manifested higher prevalence of diabetes mellitus, anemia, atrial fibrillation, anxiety, and ischemic stroke. Male patients demonstrated higher rates of previous myocardial infarction, dyslipidemia, chronic obstructive pulmonary disease, and chronic kidney disease. Higher concentrations of natriuretic peptides were observed in female patients. Renin-angiotensin aldosterone inhibitor, β blockers, mineralocorticoid receptor antagonists, sodium/glucose cotransporter 2 inhibitor (SGLT2i), and ivabradine were more commonly prescribed in male patients, whereas loop diuretics, digoxin, and ferric carboxymaltose were more frequent in female patients. Male patients had higher rates of cardiac resynchronization therapy and implantable cardioverter defibrillator implantation rates. All-cause mortality and hospitalization rates were higher in male patients. Compared with monotherapy, all combinations, including SGLT2i, showed a beneficial effect on all-cause mortality in both female and male patients with HF. In hospitalized patients with HF, the addition of digoxin to renin-angiotensin aldosterone inhibitor, mineralocorticoid receptor antagonists, and β blockers was superior to monotherapy regarding all-cause mortality in female patients with HF compared with male patients with HF. In conclusion, this study highlights that sex-specific responses to HF medication combinations compared with monotherapy and differences in co-morbidities underscore the importance of tailored management strategies. Digoxin showed a contrasting effect on all-cause mortality between both sexes after hospitalization, whereas SGLT2i exhibited a consistent beneficial effect in both sexes when added to all combinations.

Prediabetes: An overlooked risk factor for major adverse cardiac and cerebrovascular events in atrial fibrillation patients.

Prediabetes is a well-established risk factor for major adverse cardiac and cerebrovascular events (MACCE). However, the relationship between prediabetes and MACCE in atrial fibrillation (AF) patients has not been extensively studied. Therefore, this study aimed to establish a link between prediabetes and MACCE in AF patients. To investigate a link between prediabetes and MACCE in AF patients. We used the National Inpatient Sample (2019) and relevant ICD-10 CM codes to identify hospitalizations with AF and categorized them into groups with and without prediabetes, excluding diabetics. The primary outcome was MACCE (all-cause inpatient mortality, cardiac arrest including ventricular fibrillation, and stroke) in AF-related hospitalizations. Of the 2965875 AF-related hospitalizations for MACCE, 47505 (1.6%) were among patients with prediabetes. The prediabetes cohort was relatively younger (median 75 vs 78 years), and often consisted of males (56.3% vs 51.4%), blacks (9.8% vs 7.9%), Hispanics (7.3% vs 4.3%), and Asians (4.7% vs 1.6%) than the non-prediabetic cohort (P < 0.001). The prediabetes group had significantly higher rates of hypertension, hyperlipidemia, smoking, obesity, drug abuse, prior myocardial infarction, peripheral vascular disease, and hyperthyroidism (all P < 0.05). The prediabetes cohort was often discharged routinely (51.1% vs 41.1%), but more frequently required home health care (23.6% vs 21.0%) and had higher costs. After adjusting for baseline characteristics or comorbidities, the prediabetes cohort with AF admissions showed a higher rate and significantly higher odds of MACCE compared to the non-prediabetic cohort [18.6% vs 14.7%, odds ratio (OR) 1.34, 95% confidence interval 1.26-1.42, P < 0.001]. On subgroup analyses, males had a stronger association (aOR 1.43) compared to females (aOR 1.22), whereas on the race-wise comparison, Hispanics (aOR 1.43) and Asians (aOR 1.36) had a stronger association with MACCE with prediabetes vs whites (aOR 1.33) and blacks (aOR 1.21). This population-based study found a significant association between prediabetes and MACCE in AF patients. Therefore, there is a need for further research to actively screen and manage prediabetes in AF to prevent MACCE.

Protruding Aortic Plaque and Coronary Plaque Vulnerability.

Protruding aortic plaque is known to be associated with an increased risk for future cardiac and cerebrovascular events. However, the relationship between protruding aortic plaque and coronary plaque characteristics has not been systematically investigated. A total of 615 patients who underwent computed tomography angiography, and preintervention optical coherence tomography imaging were included. Coronary plaque characteristics were compared to evaluate coronary plaque vulnerability in patients with protruding aortic plaque on computed tomography angiography. 615 patients, the 186 (30.2%) patients with protruding aortic plaque were older and had more comorbidities such as hypertension, chronic kidney disease, and a prior myocardial infarction than those without. They also had a higher prevalence of coronary plaques with vulnerable features such as thin-cap fibroatheroma (85 [45.7%] versus 120 [28.0%], P<0.001), lipid-rich plaque (165 [88.7%] versus 346 [80.7%], P=0.014), macrophages (147 [79.0%] versus 294 [68.5%], P=0.008), layered plaque (117 [62.9%] versus 213 [49.7%], P=0.002), and plaque rupture (96 [51.6%] versus 111 [25.9%], P<0.001). Patients with protruding aortic plaque experienced more major adverse cardiac and cerebrovascular events, including all-cause mortality, nonfatal acute coronary syndromes, and stroke (27 [14.7%] versus 21 [4.9%], P<0.001; 8 [4.3%] versus 1 [0.2%], P<0.001; 5 [2.7%] versus 3 [0.7%], P=0.030; and 5 [2.7%] versus 2 [0.5%], P=0.013, respectively). The current study demonstrates that patients with protruding aortic plaque have more features of coronary plaque vulnerability and are at increased risk of future adverse events.

Factors associated with early, late, and very late stent thrombosis among patients with acute coronary syndrome undergoing coronary stent placement: analysis from the ATLAS ACS 2-TIMI 51 trial.

Stent thrombosis (ST) is an uncommon but serious complication of stent implantation. This study aimed to explore factors associated with early, late, and very late ST to help guide risk assessment and clinical decision-making on ST. The analysis included patients who received stent placement for the index acute coronary syndrome (ACS). Cumulative incidence of ST was assessed at 30 days (early ST), 31-360 days (late ST), 361-720 days (very late ST), and up to 720 days. Cox proportional hazards models were used to assess associations between ST and various factors, including patient characteristics [i.e., age, sex, ACS presentation, history of hypertension, smoking, diabetes, prior myocardial infarction (MI), heart failure, prior ischemic stroke, and cancer], laboratory tests [i.e., positive cardiac biomarker, hemoglobin, platelet count, white blood cell (WBC) count], and treatment [i.e., drug-eluting stent (DES) vs. bare-metal stent (BMS) and anticoagulant with rivaroxaban vs. placebo]. Among the 8,741 stented patients, 155 ST events (2.25%) occurred by Day 720. The cumulative incidences of early, late, and very late ST were 0.80%, 0.81%, and 0.77%, respectively. After multivariable adjustment, age ≥ 75 [hazard ratio (HR) = 2.13 (95% confidence interval, CI: 1.26-3.60)], a history of prior MI [HR = 1.81 (95% CI: 1.22-2.68)], low hemoglobin level [HR = 2.34 (95% CI: 1.59-3.44)], and high WBC count [HR = 1.58 (95% CI: 1.02-2.46)] were associated with a greater risk of overall ST, whereas DES [HR = 0.56 (95% CI: 0.38-0.83)] and rivaroxaban therapy [HR = 0.63 (95% CI: 0.44-0.88)] were associated with a lower risk of overall ST up to 720 days. Low hemoglobin level and high WBC count were associated with early ST (low hemoglobin: HR = 2.35 [95% CI: 1.34-4.12]; high WBC count: HR = 2.11 [95% CI: 1.17-3.81]). Low hemoglobin level and prior MI were associated with a greater risk of late ST (low hemoglobin: HR = 2.32 [95% CI: 1.26-4.27]; prior MI: HR = 2.98 [95% CI: 1.67-5.31]), whereas DES was associated with a lower risk of late ST [HR = 0.33 (95% CI: 0.16-0.67)]. Age ≥75 years was associated with very late ST. The study identified positive and negative associations with early, late, and very late ST. These variables may be useful in constructing risk assessment models for ST. http://www.clinicaltrials.gov, identifier NCT00809965.

Prescription patterns and their appropriateness within guidelines in chronic coronary syndrome patients

Chronic coronary syndrome (CCS) is a disease that can progress to an acute fatal phase, and appropriate intervention with first-line CCS drugs (aspirin, beta-blockers, angiotensin-converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB)/angiotensin receptor neprilysin inhibitor (ARNI), and statin) is crucial to reduce cardiovascular mortality. This study aims to describe the prescription patterns and their appropriateness within guidelines in CCS patients. This is a descriptive cross-sectional study conducted in a central general tertiary hospital in Bandung, where data are collected retrospectively to include CCS patients. Data are excluded when information on prescription and contraindication factors in those not receiving first-line drugs is absent. 152 patients are included for analysis, where the majority are male with a median of 60.5 years from an outpatient setting and mostly having a history of hypertension and prior myocardial infarction (MI). Most prescribed medications are first-line CCS drugs: statin (99.3%), beta-blockers (87.5%), ACEi/ARB/ARNI (87.5%), and aspirin (83.6%). In addition, 97.7% have received at least one antithrombotic, only 66.2% received high-intensity statin, and only 1.9% achieved an low-density lipid level target below 55 mg/dl. After accounting for contraindication factors, appropriateness within guidelines in CCS patients reaches 82.2%. In conclusion, most prescribed medications are first-line CCS drugs, and appropriateness within guidelines is high, but improvement in high-intensity statin use is still needed.

Prevalence of Cardiovascular Disease and Rate of Major Adverse Cardiovascular Events in Severe Alpha-1 Antitrypsin Deficiency COPD.

Alpha-1 antitrypsin deficiency is an autosomal co-dominant condition that predisposes individuals to early-onset emphysema. As with COPD, AATD-COPD is associated with pulmonary exacerbations, which impacts on overall mortality and quality of life. Though there is evidence that COPD is associated with a higher prevalence of cardiovascular disease and major adverse cardiovascular events (MACE), it is unclear if this is true for patients with AATD-COPD. Prevalence of cardiovascular disease was determined in two separate severe AATD cohorts: AlphaNet, USA and the Birmingham AATD registry, UK. All patients had preexisting lung disease. Cardiovascular disease was defined as presence of any of the following: heart failure, ischaemic heart disease, atrial fibrillation, stroke, and myocardial infarction. A Cox proportional hazards model was used to assess the impact of prior cardiovascular disease and frequent exacerbator phenotype on risk of future MACE. Out of 3493 patients with severe AATD, 14.7% had prior cardiovascular disease, including stroke (2.3%), myocardial infarction (2.2%), and heart failure (2.5%). Frequent exacerbators were more likely to have preexisting cardiovascular disease compared with those with one or no exacerbations in the preceding year (63% vs 44.8%, p = 0.001). There was increased risk of future MACE in frequent exacerbators (HR 1.85, 95% CI 1.24 to 2.75), former and current smokers (HR 1.80, 95% CI 1.07 to 3.02, p = 0.026, and HR 4.04, 95% CI 1.44 to 11.32, p = 0.008, respectively), and those with prior cardiovascular disease (HR 3.81, 95% CI 2.60 to 5.58, p < 0.001). In severe AATD-COPD, MACE are associated with an increased exacerbation frequency, previous cardiovascular disease, and a history of smoking.

Rationale and design of the effect of evolocumab in patients at high cardiovascular risk without prior myocardial infarction or stroke (VESALIUS-CV) trial

The reduction of low-density lipoprotein cholesterol (LDL-C) with evolocumab, a fully human monoclonal antibody inhibitor of proprotein convertase subtilisin/kexin type 9 (PCSK9i), reduces the risk of major adverse cardiovascular events in patients with established atherosclerotic cardiovascular disease (ASCVD) with a prior MI, prior stroke, or symptomatic peripheral artery disease, with no offsetting safety concerns. The effect of evolocumab on CV outcomes in lower risk patients without a history of MI or stroke has not been explored. VESALIUS-CV is a randomized, double-blind, placebo-controlled, global clinical trial designed to evaluate the effect of evolocumab on the risk of major cardiovascular events in patients at high cardiovascular risk but without a prior ischemic event. The study population consists of 12,301 patients with atherosclerosis or high-risk diabetes mellitus without a prior MI or stroke; an LDL-C ≥ 90 mg/dL, or non-high-density lipoprotein cholesterol (non-HDL-C) ≥ 120 mg/dL, or apolipoprotein B ≥ 80 mg/dL; and treated with optimized lipid-lowering therapy. Patients were randomized in a 1:1 ratio to evolocumab 140 mg subcutaneously every 2 weeks or matching placebo. The primary efficacy objective is to assess whether evolocumab reduces the risk of the dual primary composite endpoints of coronary heart disease (CHD) death, myocardial infarction (MI), or ischemic stroke (triple primary endpoint) and of CHD death, MI, ischemic stroke, or ischemia-driven arterial revascularization (quadruple primary endpoint). Recruitment began in June 2019 and completed in November 2021. The trial is planned to continue until at least 751 patients experience an adjudicated triple endpoint, at least 1254 experience an adjudicated quadruple endpoint, and the median follow-up is ≥4.5 years. VESALIUS-CV will determine whether the addition of evolocumab to optimized lipid-lowering therapy reduces cardiovascular events in patients at high cardiovascular risk without a prior MI or stroke.

RECURRENT FALLS IN OLDER ADULTS ARE ASSOCIATED WITH MORTALITY AND HOSPITALIZATION

Abstract Annually, 1 in 4 older adults fall and roughly half have a second fall within 6 months. We studied 57 hospitals in the TriNetX Network. We included all older adults discharged home from the emergency department (ED) after a fall in 2022 for a total of 89,061 patients. Of these, 13,389 (15%) patients returned to the ED for another fall within 6 months. Patients with repeat falls were older (78.7 vs 76.5 years), more likely to have hypertension (76 vs 56%), prior myocardial infarction (14 vs 3%), heart failure (29 vs. 15%), peripheral vascular disease (18 vs 10%), cerebrovascular event (19 vs 10%), chronic obstructive pulmonary disease (COPD) (23 vs 14%), diabetes (40 vs 23%), liver disease (17 vs 11%), chronic kidney disease (30 vs 16%), and cancer (45 vs 32%); P&amp;lt; 0.001. Patients with recurrent falls were more likely to be prescribed cardiovascular medications (84 vs. 66%), central nervous system medications (87 vs 69%), opioids (71 vs 52%), sedatives/hypnotics (59 vs 42%), antipsychotics (23 vs 12%), antidepressants (51 vs 32%), antiparkinsonian agents (9 vs 4%), and antivertigo agents (15 vs 9%); P&amp;lt; 0.001. Patients with a recurrent fall within 6 months had higher hospital admission rate (46.2 vs 15.8%, OR 4.6 [95%CI, 4.4-4.7]) and higher mortality rate (6.2 vs 3.5%, OR 1.83 [95%CI 1.7-2.0]). Older adults discharged home from the ED after falling are at high risk of a second fall and those who have a repeat fall within 6 months are at higher risk of hospital admission and mortality.

Classification of longitudinal strain curves measured by speckle-tracking echocardiography in normal and pathological myocardial segments

Abstract Background Two-dimensional speckle-tracking echocardiography (2D-STE) provides a quantitative tool to evaluate LV function at the regional level. The purpose of this study was to classify the types of regional longitudinal strain curves (LSC). Moreover, we propose a novel longitudinal strain curve index (LSCI) which we compared to the wall motion score index (WMSI). Methods We enrolled 100 healthy volunteers and 50 patients with prior myocardial infarction (MI). Each LSC was classified considering the positive peak (peak P), peak maximum strain (PMS), and time to maximum peak strain (TPMS) as follows: Type 1 (Peak P&lt;6%, PMS&gt;6%, TPMS before aortic valve closure [AVC]); Type 2 (Peak P&lt;6%, PMS≥6%, TPMS after AVC); Type 3 (Peak P≥6%, PMS≥6%, TPMS before AVC); Type 4 (Peak P≥6%, PMS≥6%, TPMS after AVC); Type 5 (Peak P&lt;6%, PMS≥6%, TPMS first third of systole); Type 6 (Peak P&lt;6%, PMS&lt;6%); and Type 7 (Peak P≥6%, PMS&lt;6%). The longitudinal curve score index (LCSI) was obtained (sum of LSC type/18 segments). Results A total of seven types of LSC were identified. In the healthy subjects, LSC Type 1 (T1) and Type 2 (T2) were the most frequent. Type 3 (T3) and Type 4 (T4) were found in insignificant percentages while Type 5 (T5), Type 6 (T6), and Type 7 (T7) were not identified. When analyzed for the entire population, LSCI correlated strongly with WMSI (r=0.83, p&lt;0.01). Conclusions Analysis of LSC may provide a substantial support to visual assessment of regional LV function and the LCSI represents an index that is highly reproducible, independent of the examiner’s experience.

DETERMINANTS OF MYOCARDIAL INFARCTION OUTCOMES IN A NON-PERCUTANEOUS CORONARY INTERVENTION HOSPITAL IN JAKARTA

Background: Global cardiovascular challenges persist, notably in myocardial infarction (MI). Despite studying factors such as age, sex, MI type, and comorbidities impacting survival, knowledge gaps exist, particularly in Indonesia without recent MI data, especially in non-PCI settings.&#x0D; Objectives: This study seeks to bridge the knowledge gap concerning determinants of post-MI survival in hospitals without PCI facilities in Jakarta, Indonesia.&#x0D; Methods: Adopting a retrospective cross-sectional design, 112 medical record patients from an Emergency Department of non-PCI hospital in Jakarta were selected via purposive sampling. A structured checklist was utilized to assess 16 variables and the primary endpoint was post-treatment status. The study employed Chi-square, Fisher's exact, and Likelihood ratio tests to analyze the relationship between demographics, risk Factors, and MI treatment access and the post-treatment status.&#x0D; Results: Results highlighted that of 112 myocardial infarction (MI) patients, males constituted 70.5%, with Non-ST Elevation Myocardial Infarction as the predominant subtype (57.1%). Most participants (86.6%) were ≥45 years old. Prevalence rates included hypertension (56.3%), Diabetes Mellitus (40.2%), Congestive Heart Failure (42.0%), and prior MI (27.7%). Post-MI survival stood at 92.9%, with 7.1% mortality. The results revealed a significant correlation between cardiogenic shock and MI outcomes (p=0.000), indicating a protective advantage (OR: 0.018) for those without cardiogenic shock against MI-related mortality.&#x0D; Conclusion: While cardiogenic shock has been reaffirmed as the sole predictor of post-myocardial infarction mortality in our study, it's crucial to heighten awareness of other MI determinants, including age, gender disparities, smoking status, and the dynamics of therapeutic measures. This underlines the pressing need for early identification and evidence-based management strategies.&#x0D;

Unraveling the Link: Cannabis Use Disorder and Pulmonary Embolism-Related Hospital Outcomes in Female Breast Cancer Survivors

Background: The use of cannabis in cancer patients has gained significant attention due to its analgesic properties, which help alleviate cancer-related pain. Studies have also shown the interference of cannabis with the coagulation system. We aimed to study the impact of cannabis use disorder (CUD) and Pulmonary embolism (PE) on outcomes in female breast cancer survivors, considering reports suggesting significant overlap between recreational and medicinal use. Our objective was to compare outcomes in CUD+ (with cannabis use disorder) and CUD- (without cannabis use disorder) cohorts to gain critical insights into this group and understand the impact of CUD on PE-related hospitalization and outcomes. Methods: National Inpatient Sample (NIS) data from 2020 was utilized in order to analyze inpatient cohorts of PE hospitalizations. The International Classification of Diseases 10 (ICD 10) codes for pulmonary embolism, cannabis use disorder, and female breast cancer were utilized to classify cohorts. All cases of female breast cancer and pulmonary embolism with an age &amp;gt;18 years were included in the final analysis. The primary outcome was the impact of CUD on PE-related hospitalizations in female breast cancer survivors. We also compared demographic correlations and comorbidities affecting outcomes between cohorts. Results: This study included a total of 508065 admissions among breast cancer survivors, with a median age of 74 years for the entire cohort. The prevalence of PE admissions was lower in CUD+ cohort compared to CUD- cohort (1.3% vs. 2.1%). The CUD+ cohort was relatively younger (median 66 vs 74 years, p&amp;lt;0.001). Overall, admission rates were higher among white patients (77%) and this trend was statistically significantly higher in the 76-100 th percentile household income group (p&amp;lt;0.002) compared to CUD+(50%) and CUD-(26.5%). Most admissions were non-elective (95.4%), with no statistical significance between CUD- and CUD+ patients (p=0.16). The majority of readmissions occurred in urban teaching hospitals (75.5%), with no significant difference observed between CUD- and CUD+ patients (p=0.111). Regionally, the South had a higher admission rate (37.2%) compared to other regions and this difference was statistically significant (p&amp;lt;0.001) between CUD- and CUD+ patients. Among the coexisting comorbidities, hypertension showed a significant difference between CUD- (70%) and CUD+(37.5%) patients (p&amp;lt;0.001). Alcohol use disorder (p&amp;lt;0.001) and cancer (p&amp;lt;0.001) had significant associations with CUD+, along with prior myocardial infarction (p=0.005) and drug use (p&amp;lt;0.001) were significantly associated with CUD+.Furthermore, there was difference in routine patient disposition between between CUD-(45.3%) and CUD+(37.5%),(p=0.033) and length of stay (4 VS 2 days), (p=0.033) and cost of stay (47033 vs 27668 $), (p=0.017). The multivariable logistic regression analysis showed that the odds of PE-related hospitalization in CUD+ vs CUD- cohorts among female breast cancer survivors were not statistically significant, with an OR of 0.79 (CI: 0.38-1.62, p=0.512). Subgroup analysis by age demonstrated no statistically significant differences in odds for PE-related hospitalization between CUD+ and CUD- cohorts. For the age group of 18-44 years, the OR was 1.37 (CI: 0.18-10.60, p=0.762). In the 45-64 years age group, the OR was 0.48 (CI: 0.15-1.53, p=0.215), and for those aged ≥65 years, the OR was 1.32 (CI: 0.48-3.67, p=0.590). Furthermore, the analysis by race indicated that the odds of PE-related hospitalization did not reach statistical significance in both white and black female breast cancer survivors with CUD. For white patients, the OR was 0.64 (CI: 0.23-1.73, p=0.375), while for black patients, the OR was 1.15 (CI: 0.38-3.46, p=0.804). Conclusion: Among female breast cancer survivors, the presence of CUD did not show a statistically significant impact on the odds of PE-related hospitalization. Subgroup analysis by age and race also revealed no significant differences in the odds of PE-related hospitalization between CUD+ and CUD- cohorts. These findings underscore the importance of considering CUD when managing pulmonary embolism in breast cancer survivor females and emphasize the need for further research to understand the complex interplay between these factors.
