Diabetes and cardiovascular disease, are women protected or at higher risk?Journal of Nuclear Cardiology
Nathan Gargus, et al.
For many years, data have accumulated demonstrating that diabetes mellitus (DM) promotes atherosclerosis progression and imparts risk of major adverse cardiovascular events (MACE), including revascularization, myocardial infarction (MI), and cardiac death. Among patients without known cardiovascular disease (CVD), having DM is a “risk equivalent,” meaning that they are at the same risk of MACE as a patient with known CVD.
Ethnic comparison in takotsubo syndrome: novel insights from the International Takotsubo RegistryClinical Research in Cardiology
Yoichi Imori, et al.
Ethnic disparities have been reported in cardiovascular disease. However, ethnic disparities in takotsubo syndrome (TTS) remain elusive. This study assessed differences in clinical characteristics between Japanese and European TTS patients and determined the impact of ethnicity on in-hospital outcomes. TTS patients in Japan were enrolled from 10 hospitals and TTS patients in Europe were enrolled from 32 hospitals participating in the International Takotsubo Registry.
The New Role of Telehealth in Contemporary MedicineCurrent Cardiology Reports
Morgan H. Randall and David E. Winchester
Understand the current uses for telehealth as well as future directions as it relates to the COVID-19 pandemic and cardiovascular medicine. Telehealth interventions in various forms have proven to be efficacious in the management of obesity, hypertension, glycemic control in diabetes, hyperlipidemia, medication adherence, and ICU length of stay and mortality. The use and study of such interventions have been greatly expanded during the pandemic partly due to the expanded coverage by payers.
