Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Signal frequency dependence of ionospheric amplitude scintillations

open access: yes, 1990
The S4 index, which is a measure of the strength of amplitude scintillations, is assumed to vary with signal frequency f according to S4αf-n, and the frequency exponent n is derived from observed equatorial amplitude scintillations on 40- and 140 ...

A phenomap of TTR amyloidosis to aid diagnostic screening

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.
