Light-chain-related amyloidosis is a systemic disease characterized by continuous accumulation of insoluble fibrillar proteins in different organs. Cardiac involvement is frequent in this condition. However, atypical presentations and unusual amyloid deposits localization may be encountered making the diagnosis challenging. We present here a case of a light-chain-related pericardial amyloidosis without evidence of myocardial involvement and emphasize the difficulty and importance of amyloidosis typing before starting treatment.

Increased activity of acid sphingomyelinase (ASMase) has been linked to diabetes and organ fibrosis. Nevertheless, the precise influence of ASMase on diabetic myocardial fibrosis and the corresponding molecular mechanisms remain elusive. In this study, we aim to elucidate whether ASMase contributes to diabetic myocardial fibrosis through the phosphorylation mediated by MAPK, thereby culminating in the development of diabetic cardiomyopathy (DCM).

Cardiac involvement in cancer is increasingly important in the diagnosis and follow-up of patients. A thorough cardiovascular evaluation using multimodal imaging is crucial to assess any direct cardiac involvement from oncological disease progression and to determine the cardiovascular risk of patients undergoing oncological therapies. Early detection of cardiac dysfunction, particularly due to cardiotoxicity from chemotherapy or radiotherapy, is essential to establish the disease's overall prognostic impact.

: Takotsubo syndrome (TTS) shares many clinical features with acute myocardial infarction (AMI); however, its underlying pathophysiology remains elusive due to specific characteristics (i.e., reversibility, presence of stressors, and low mortality rate).

Cardiovascular diseases such as myocardial infarction or limb ischemia are characterized by regression of blood vessels. Local delivery of growth factors (GFs) involved in angiogenesis such as fibroblast blast growth factor-2 (FGF-2) has been shown to trigger collateral neovasculature and might lead to a therapeutic strategy. In vivo, heparin, a sulfated polysaccharide present in abundance in the extracellular matrix (ECM), has been shown to function as a local reservoir for FGF-2 by binding FGF-2 and other morphogens and it plays a role in the evolution of GF gradients.

Two billion people worldwide suffer from anemia, which can lead to the onset of cardiac disorders; nevertheless, the precise mechanisms remain unclear. There are at least three distinct mechanisms by which iron deficiency (ID) contributes to the development of cardiac disorders. First, ID increases concentrations of intact fibroblast growth factor-23 (iFGF-23), which promotes left ventricular hypertrophy.
