Phenotype and prognostic factors in geriatric and non-geriatric patients with transthyretin cardiomyopathy.
Observational study in ESC heart failure, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsTransthyretin cardiac amyloidosis (ATTR-CM) may be an underestimated cause of heart failure among geriatric patients and represent a unique phenotype and prognostic profile. METHODS AND
resultsThis retrospective, observational, cohort study characterizes cardiac and extracardiac disorders at diagnosis and assesses prognosis among ATTR-CM patients based on age (geriatric vs. non-geriatric) and amyloidosis subtype (wild type, ATTRwt and hereditary, ATTRv). In total, 943 patients with ATTR-CM were included, of which 306 had ATTRv and 637 had ATTRwt. Among these, 331 (35.1%) were non-geriatric (<75 years), and 612 (64.9%) were geriatric (≥75 years). The population exhibited conduction abnormalities, atrial fibrillation and ischaemic heart disease that progressively deteriorated with age. Among ATTRwt patients, peripheral neuropathy, neurovegetative symptoms, and hearing loss were present across all age groups, but reports of carpal tunnel symptoms or surgery decreased with age. Conversely, among ATTRv patients, reports of extracardiac symptoms increased with age and Val122ILe mutation was highly prevalent among geriatric patients. The 3-year survival was higher among non-geriatric ATTR-CM patients (76%) than geriatric patients (55%) and predictors of 3-year mortality differed. Notably, predictors identified among geriatric patients were alkaline phosphatase (ALP) (HR = 1.004, 95% CI: [0.001-1.100)], troponin T hs (HR = 1.005, 95% CI: [1.001-1.120)] and tricuspid insufficiency (HR = 1.194, 95% CI: [1.02-1.230)]. Whereas, among non-geriatric patients, NT-proBNP (HR = 1.002, 95% CI: [1.02-1.04], global longitudinal strain (HR = 0.95, 95% CI: [0.922-0.989], and glomerular filtration rate (HR = 0.984, 95% CI: [0.968-1.00) were identified. We propose a 3-stage prognostic staging system combining troponin T hs (≥44 ng/L) and ALP levels (≥119 UI/L). In the geriatric population, this model discriminated survival more precisely than the National Amyloidosis Centre staging, particularly for classifying between stage 1 (82%), stage 2 (50%) and stage 3 (32%) for ATTRv and ATTRwt.
conclusionsThese diagnostic and prognostic indicators, along with ATTR subtype, highlight the distinct characteristics of this important, geriatric ATTR-CM patient group. Recognizing these mortality markers can be valuable for geriatricians to improve the prognostic quality management of geriatric patients with ATTR-CM.
