Cardiac amyloidosis is a manifestation of amyloidosis which is a multisystem disorder. This is difficult to diagnose, rare disease which eventually leads to the mortality. Diagnosis requires a high index of clinical suspicion along with echocardiographic clues like, diastolic dysfunction, bi-atrial enlargement and ventricular thickening. Treatment is mainly supportive with disappointing outcomes. We present a case of systemic amyloidosis with negative congo red staining, presenting with predominantly cardiac features.

Background: Speckles tracking echocardiography imaging enables clinicians to detect subtle systolic dysfunction. The aim of the present study was to elucidate the differences in speckle tracking echocardiographic findings between immunoglobulin light chain amyloid cardiomyopathy (AL-CM) and transthyretin amyloid cardiomyopathy (TTR-CM).
Methods: The patients with a confirmed diagnosis of cardiac amyloidosis through cardiac biopsy from March 2013 to October 2022 were included.

Primary amyloidosis (AL type) is a systemic disease that can lead to structural and functional damage to organs and tissues such as the kidney, heart and liver with non-specific symptoms. Most of the affected patients develop thyroid infiltration and thus diffuse enlargement of the thyroid gland, while cases leading to hypothyroidism are exceedingly rare. Some researchers have analyzed thyroid function in newly diagnosed patients with AL amyloidosis, and found that the incidence of overt hypothyroidism is only 7%.

Background: Despite previous histopathologic evidence for its presence, the role of myocardial inflammation in the development and progression of cardiac transthyretin amyloidosis (ATTR-CA) remains insufficiently understood. Thus, this study sought to characterize the prevalence and potential prognostic implications of myocardial inflammation in ATTR-CA.
Methods: A retrospective observational study including patients with ATTR-CA diagnosed by endomyocardial biopsy was conducted.
