چکیده

Abstract Purpose We described the incidence and ECG factors associated with de novo atrial fibrillation (AF) in patients diagnosed wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) to drive tailored arrhythmia screening. Background Data on rate AF ATTRwt CA is limited. Methods Multicenter, retrospective, observational cohort study performed six referral centers for CA. All consecutive ATTRwt-CA between 2004 2020 >1-year follow up (FU) were enrolled divided into three groups according presence of AF: (1)patients ‘known AF’; (2)patients ‘sinus rhythm’ (3)patients developing ‘de AF’ during FU. Incidence primary outcomes. Results Overall, 266 followed a median 469 days: 148 (56%) known AF, 84 (31.6%) sinus rhythm, 34 (12.8%) AF. Age gender similarly distributed. At multivariable analysis, PR (Hazard Ratio[HR]: 1.008 95% C.I. 1.001-1.016), QRS (HR: 1.022 1.002-1.043) left dilatation>50mm 3.429 1.565-7.329) at Patients presenting least two risk (PR>200ms, QRS>120ms or LAD>50mm) had higher compared no (HR 14.918 3.242-31.646). Conclusions 20.7%/year. Longer duration dilation are onset.

Wild-type transthyretin amyloidosis in female patients

Results Comparison of clinical findings between males and females affected by wt-ATTR amyloidosis are shown in table 1. Female patients with wt-ATTR did not differ from male patients regarding demographic or clinical parameters except for modified body mass index (1140±184 vs. 1029±154, p<0.05), glomerular filtration rate (66±23 vs. 85±31 ml/min*m*1.73; p<0.05), NYHA class (2.4±0.7 vs. 2.9±0.3;...

Pressure-volume relationships in patients with transthyretin (ATTR) cardiac amyloidosis secondary to V122I mutations and wild-type transthyretin: Transthyretin Cardiac Amyloid Study (TRACS).

BACKGROUND ATTR cardiac amyloidosis can result from a mutated variant of transthyretin (eg, V122I) or wild-type variant (ATTRwt). We evaluated pressure-volume (PV) indices at baseline and over time to further characterize abnormal pump function in these subjects. METHODS AND RESULTS Twenty-nine subjects (18 with ATTRwt and 11 with ATTRm (V122I) had 2-dimensional echocardiograms with complete ...

Green tea extract as a treatment for patients with wild-type transthyretin amyloidosis: an observational study

BACKGROUND Causative treatment of patients with wild-type transthyretin amyloid cardiomyopathy (wtATTR-CM) is lacking. Recent reports indicate the potential use of epigallocatechin-3-gallate (EGCG), the most abundant catechin in green tea, to inhibit amyloid fibril formation. We sought to investigate changes of cardiac function and morphology in patients with wtATTR-CM after consumption of gree...
