Testosterone therapy is commonly utilized to treat hypogonadism. After diagnosis with morning serum testosterone level in patients with symptoms of hypogonadism, therapy has been shown to improve symptoms. Research focusing on cardiovascular risks associated with testosterone therapy have produced contradictory statements. We review trials that have investigated the impact of testosterone supplementation on heart failure, coronary artery disease, and myocardial ischemia.

Background Amyloidosis is a systemic disorder of abnormal protein folding and deposition resulting in a range of symptoms including neuropathy, heart failure, renal disease, and dermatologic findings. The two most common types of amyloidosis that affect the heart are transthyretin (ATTR) amyloidosis and light chain (AL) amyloidosis, which vary in clinical presentation. Skin findings such as periorbital purpura are considered more specific for AL amyloidosis. However, there are rare cases of ATTR amyloidosis causing the same dermatologic findings. Case Summary A 69-year-old female presented for evaluation of amyloidosis after cardiac imaging done at the time of a recent atrial fibrillation ablation showed signs of infiltrative disease. On examination, she had periorbital purpura which she reportedly had for years without receiving a diagnosis, as well as macroglossia with teeth indentation. These exam findings, in addition to her transthoracic echocardiogram showing apical sparing, are typically considered characteristic of light chain amyloidosis. Subsequent workup revealed the presence of hereditary transthyretin amyloidosis (hATTR) with a heterozygous pathogenic variant in the TTR gene producing the p.Thr80Ala mutation. Conclusion Spontaneous periorbital purpura is thought to be pathognomonic for light chain (AL) amyloidosis. However, we describe a case of hereditary transthyretin amyloidosis (ATTR) with the Thr80Ala TTR genetic variant presenting initially with periorbital purpura, the first case documented in the literature to our knowledge.

Background and Objective: The published cardiology literature is critical for scientific communication, and we sought to determine if the published clinical cardiology evidence base has evolved over time. Methods: We evaluated the cardiology related publications in the medical journals (M) JAMA (J) and the New England Journal of Medicine (N) and all publications by the specialty journals (CA) Circulation (Ci) and the European Heart Journal (E) in 2000, 2010, and 2020 and added 2001, 2011, and 2021 for JAMA to account for potential annual variability. Results: Publication information is shown in the graph. For the M journals there has been an increase in the percentage of randomized controlled trials (RCT). For the CA journals there has been a significant decrease in single center studies (Si) and a proportionate increase in reanalysis (Re) of data whether from subanalysis of an RCT, registry, or meta-analysis. For CA journals there has been an increase in the size of clinical studies mainly due to the use of larger datasets from registries or claims (Ci: 2000: 4,500/study; 2010: 9,298/study; 2020: 258,725/study and E: 2000: 2,282/study; 2010: 12,652/study; 2020: 249,388/study). CA journals have an increased of studies with patients from multiple continents (Ci: 2000: 5.5%; 2010: 13%; 2020: 35% and E: 2000: 7%; 2010: 14.8%; 2020: 18.8%). There has been an increase in the percentage of clinical studies with documentation of different populations by region or color (In 2020, 58% for all Ci articles and 52% for US and multicontinental EHJ articles), although the number of nonwhites remains small in most studies unless the study was specifically addressing disparities in care. Conclusions: Over the last two decades, the published evidence base has changed with more RCT in the Med journals and more studies that reanalyze large datasets in CA journals. Published studies are now larger, more likely to involve multiple continents, and document population details.
