UNASSIGNED: Low QRS voltages (LQRSVs) are a common electrocardiographic feature in patients with light chain amyloidosis (AL) and transthyretin amyloidosis (ATTR) cardiac amyloidosis (CA).
UNASSIGNED: The aim of this study was to identify clinical and echocardiographic correlates of LQRSV and to investigate their prognostic significance in patients with CA.
UNASSIGNED: This was a multicenter, retrospective study performed in 6 CA referral centers including consecutive patients with AL and ATTR CA. LQRSVs were defined as a QRS amplitude ≤5 mm (0.5 mV) in all peripheral leads. The study outcome was cardiovascular (CV) mortality.
UNASSIGNED: Overall, 411 (AL CA: n = 120, ATTR CA: n = 291) patients were included. LQRSVs were present in 66 (55%) patients with AL CA and 103 (35%) with ATTR CA (P < 0.001). In AL CA, LQRSVs were independently associated with younger age (P = 0.015), higher New York Heart Association functional class (P = 0.016), and natriuretic peptides (P = 0.041); in ATTR CA, LQRSVs were independently associated with pericardial effusion (P = 0.008) and lower tricuspid annulus peak systolic excursion (P = 0.038). During a median follow-up of 33 months (Q1-Q3: 21-46), LQRSVs independently predicted CV death in both AL CA (HR: 1.76; 95% CI: 2.41-10.18; P = 0.031) and ATTR CA (HR: 2.64; 95% CI: 1.82-20.17; P = 0.005). Together with the National Amyloidosis Centre (NAC) staging, LQRSVs provided incremental prognostic value in ATTR CA (AUC for NAC model: 0.83 [95% CI: 0.77-0.89]; AUC for NAC + LQRSV model: 0.87 [95% CI: 0.81-0.93]; P = 0.040).
UNASSIGNED: LQRSVs are common but not ubiquitous in CA; they are more frequent in AL CA than in ATTR CA. LQRSVs reflect an advanced disease stage and independently predict CV death. In ATTR CA, LQRSVs can provide incremental prognostic accuracy over the NAC staging system in patients with intermediate risk.

UNASSIGNED: Clinicians have limited time during patient encounters which can result in patients\' concerns not being addressed. This study\'s objective was to test whether an electronic patient-reported outcome quality of life tool (PROQOL) in which patients identify their primary concern during clinic visits improves cancer patient quality of life (QOL).
UNASSIGNED: This single center non-blinded prospective clinical trial randomized patients (2:1) to PROQOL versus usual care (UC). Two patient cohorts were enrolled: those with hematologic malignancies (multiple myeloma [MM] or light chain amyloidosis [AL]) and solid tumors (head and neck [H/N] or gynecologic [GYN] malignancies). Primary endpoint was patient-reported QOL at 12 months measured by a single-item Linear Analog Self-Assessment. Value to patients and impact on clinician workflow was measured using a \"was it worth it\" survey. The study was powered to detect a 0.5 standard deviation difference between groups.
UNASSIGNED: Overall 383 patients were enrolled, 171 with MM, 62 AL, 113 GYN, and 37 H/N between July 2016 and April 2018, with 12-month follow-up. There were 171 (44.6%) male patients and median age was 62 years (range 31-87). The most often selected concern was physical health (30.9%), and second was cancer diagnosis and treatment (29.1%). Mean QOL was 7.12 for PROQOL and 6.98 for UC (0-10 scale) at 12 months, with no between-group difference overall (p = 0.56) or within hematologic or solid tumor cohorts, respectively. Among patients, 74% thought the PROQOL tool was worthwhile, 86% would choose PROQOL again, and 81% would recommend it to others. Among clinicians, 95% responded that PROQOL was worthwhile and did not think that PROQOL negatively impacted their workflow.
UNASSIGNED: Although we did not demonstrate a QOL difference between PROQOL and UC groups; the PROQOL tool held considerable value in identifying patients\' main concerns over time and was worthwhile for patients and clinicians.

Cardiac amyloidosis (CA) has emerged as a previously underestimated cause of heart failure and mortality. Underdiagnosis resulted mainly from unawareness of the true disease prevalence and the non-specific symptoms of the disease. CA results from extracellular deposition of misfolded protein fibrils, commonly derived from transthyretin (ATTR) or immunoglobulin light chains (AL). A significant proportion of older patients with heart failure and other extracardiac manifestations suffer from ATTR-CA, whereas AL-CA is still considered a rare disease. This article provides an overview of CA with a special focus on current and emerging diagnostic modalities. Furthermore, we provide a diagnostic algorithm for the evaluation of patients with suspected CA in every-day practice.

Cardiac amyloidosis is a restrictive cardiomyopathy that results from the deposition of misfolded light chain or transthyretin proteins, most commonly, in cardiac tissue. Traditionally, treatment options for light chain (AL) and transthyretin (ATTR) amyloidosis have been limited. However, there are now multiple novel therapeutics in development and several therapeutics recently approved that promise to revolutionize clinical management of AL and ATTR. Most of these agents disrupt specific stages of amyloidogenesis such as light chain or transthyretin protein production, formation of amyloidogenic intermediates, or amyloid fibril aggregation. Others aim to remove existing amyloid tissue deposits using monoclonal antibody technology. Although these advances represent an important step forward in the care of cardiac amyloidosis patients, additional studies are needed to define the optimal treatment paradigms for AL and ATTR and to validate clinical, imaging, or serum biomarker strategies that may confirm a cardiac response to therapy.
