In Reply Our study adjusted the FIT cutoff to yield the same overall positivity rate as reported for the mt-sRNA test (17%) to enhance comparability of diagnostic performance of both tests. Below we address each of the 3 points made by Drs Yang and Ma.

Gastric cancer is a leading cause of cancer death globally. Although endoscopy-based screening has led to a decrease in gastric cancer mortality in Eastern Asian countries with populations at high risk, lack of risk stratification and the cost of health care infrastructure and trained personnel limit its use in most of the world. Availability of noninvasive biomarkers for the identification of high-risk individuals could optimize endoscopy-based screening programs for a more general application, including in regions where gastric cancer rates in the general population are low.

To the Editor We read with interest the recent study that compared the fecal immunochemical test (FIT) positivity threshold vs multitarget stool RNA (mt-sRNA) testing for colorectal cancer screening. However, we have concerns regarding the study methodology and the capability of FIT to fully replace the mt-sRNA panel.

Objectives
This study developed and investigated the possibility of using the walking and turning test (WTT) to indicate fall risk in community-dwelling older adults.

Design
Retrospective diagnostic study.

Setting
The study was carried out in a community setting.

Participants
The study focused on community-dwelling older Thai adults.

Primary and secondary outcome measures
The participants were assessed based on demographics, fear of falls using a ‘yes/no’ question and the Short Falls Efficacy Scale International, as well as fall data in the previous 6 months. The participants then performed the WTT, timed up and go test, five times sit-to-stand test and handgrip strength test (HG) in random order.

Results
There were a total of 86 participants with an average age of 69.95±6.10 years (range from 60 to 88 years), most of whom were female (67.44%). 40 participants (46.51%) reported that they had fallen at least once in the previous 6 months. A comparison of various physical ability tests revealed significant differences between faller and non-faller participants (p

Circulation, Volume 150, Issue Suppl_1, Page A4146434-A4146434, November 12, 2024. Background:PET/CT stress test may be performed to risk stratify patients including those without known coronary artery disease (CAD) who may be at risk for short-term adverse cardiac events. In patients with low- to moderate (LTM) risk for short-term MACE and without a known history of CAD, a small percentage of these patients will undergo a coronary angiogram within 90-days, of which some will be diagnosed with high-grade stenosis. The purpose of this study is to determine factors associated with this approach and findings.Methods:Patients without a history of known CAD (n=43,271) undergoing a PET/CT from 2018-2023 at Intermountain Health, with scan interpreted clinically as LTM short-term risk for adverse cardiac events, and ischemic burden 70% stenosis in any vessel), an a priori list of clinical data and PET/CT results were examined.Results:Within 90 days of the LTM risk PET/CT, 3,163 (8.2%) had a coronary angiogram. Of these, 806 (25.5% of angiograms and 2.1% of total LTM) had high-grade CAD. The PET/CT ancillary findings were associated with the largest odds of performing an angiogram and the presence of high-grade CAD (Tables). Factors most likely to be associated with performing an angiogram were an ischemic burden of 7.5-10% (adjusted-OR [adj. OR]=11.54), coronary artery calcification (CAC) score of >300 (adj.-OR =1.62), and myocardial blood flow (MBF) of MBF 2.3). Other clinical parameters associated, after adjustment, with an angiogram were age, male sex, hypertension, elevated troponin, and inpatient status. Many of the same factors were found to be associated with the identification of high-grade CAD. However, being an inpatient was associated with increased odds of angiogram but a decrease in odds of high-grade CAD.Conclusions:In patients without a known history of CAD who underwent PET/CT clinically adjudicated as LTM short-term risk and ischemic burden

Circulation, Volume 150, Issue Suppl_1, Page A4141670-A4141670, November 12, 2024. Background:Whole blood gene expression is modified in response to signals from various tissues, including the liver. Steatotic (fatty) liver disease (SLD) is a hallmark of cardiometabolic disorder strongly associated with vascular disease (50% of patients undergoing coronary angiography). The main goal of this study was to evaluate the classification performance of peripheral whole blood RNAseq analyzed by artificial intelligence (AI) in identifying or ruling out SLD.Methods:The training set consisted of 118 men 40-70 years and women 50-70 years with no history of cardiovascular disease enrolled in a clinical study for assessing coronary artery calcification via a chest computed tomography scan. SLD was defined as

Circulation, Volume 150, Issue Suppl_1, Page A4143109-A4143109, November 12, 2024. Background:The use of cardiac resynchronization therapy (CRT) devices has significantly increased in usage in recent years. Identifying predictors of mortality in CRT patients remains an area of investigation.Objective:To establish a relationship between timed up-and-go test time (TUGT) and mortality in heart failure patients (HF) with CRT devices.Methods:This retrospective study included 506 patients with heart failure with reduced ejection fraction (HFrEF) who underwent CRT implantation at our institution between 2017-2022. All patients were followed up with a multidisciplinary team, including electrophysiology and HF physicians about 6 months after CRT implantation, where frailty was assessed. We used TUGT as a measure of frailty and divided patients into 2 groups: TUGT: >15 seconds (n=73) and ≤15 seconds (n=433). The primary endpoint was a composite of left ventricular assist device implantation, transplant, or death at 2 years post-CRT. Data was collected retrospectively from electronic medical records.Results:The study population was 65.6% male, with a mean age of 69.1 years, and 79.4% of devices being CRT-D.Response was defined as an improvement in LVEF >5% with reduction in LVESV >10%; anybody not meeting this definition was classified as a non-responder. Responder and non-responder rates among TUGT >15 and TUGT15s have worse outcomes (Figure 1).Conclusion:Frailty testing using TUGT post-CRT implantation is a strong predictor of mortality in HFrEF patients after CRT implantation.

Circulation, Volume 150, Issue Suppl_1, Page A4140902-A4140902, November 12, 2024. BACKGROUND:Coronary artery spasm (CAS) is a cause of variant angina and is typically diagnosed by intracoronary provocation test. Investigations regarding association between the burden of coronary artery stenosis and the minimum responsive dose of ergonovine (ERG) required for provocation is limited.METHODS:In this study, 356 patients who underwent the ergonovine (ERG) provocation test and showed CAS between October 2004 and December 2022 were enrolled. Significant CAS was defined as temporary narrowing of ≥70% during the ERG test. Patients were divided into three groups, based on the minimum responsive dose of ERG: E1 group (20ug, n=13), E2 group (40ug, n=53) and E3 group (80ug, n=290).RESULTS:In patients who were documented with positive intracoronary ERG provocation test, 3.7% responded at the lowest dose (20ug), 14.9% responded at the medium dose (40ug) and 81.5% responded only at the highest dose of ERG (80ug). The baseline characteristics of the patients among the 3 groups were similar, demonstrating no significant difference in the prevalence of hypertension, diabetes mellitus, and dyslipidemia. However, patients who responded at E2 dose showed higher proportion of smokers than E3 dose (E2 34.0% vs. E3 25.9%, p=0.043). E1 group demonstrated the highest proportion of severe stenosis (92.3%), followed by E2 group (90.6%) and E3 group (71.4%) (Figure 1). In addition, incidence of focal CAS and multi-vessel CAS were higher among those who responded to lower doses (focal CAS: 23.1% vs. 20.8% vs. 10.0%; multi-vessel CAS: 61.5% vs.50.9% vs. 36.6%).CONCLUSION:In patients with chest pain with positive intracoronary ERG provocation test, higher burden of stenotic lesions was found to be more frequent and more susceptible in patients who responded at lower doses of ERG.
