Vasovagal Syncope: A Review of Current and Emerging Therapies for a Common Cardiology Condition.

J Tehran Heart Cent

January 2024

Department of Cardiac Sciences, Libin Cardiovascular Institute, Cumming School of Medicine, University of Calgary, Calgary, Alberta, Canada.

Vasovagal syncope (VVS), characterized by transient loss of consciousness, is among the most prevalent reasons for emergency visits worldwide. Although benign in nature, VVS can be accompanied by traumatic injury, leading to morbidity and decreased quality of life, especially in those with VVS recurrence. The management includes non-pharmacologic and pharmacologic therapies (if resistant), patient education and reassurance, salt and fluid intake increase, and physical counter-pressure maneuvers.

Background: Right ventricular (RV) stroke volume (SV) can be calculated via Doppler echocardiography at multiple sites in the right chambers. However, the agreement between the calculated SVs at these sites is unknown. We aimed to assess the repeatability, reliability, and precision of the distal right ventricular outflow tract diameter (RVOTD), the mid-pulmonary artery diameter (MPAD), the right ventricular outflow tract velocity time integral (VTI), and the mid-pulmonary artery velocity time integral (MPAVTI).

Article Synopsis
  • - The systematic review and meta-analysis explored the link between blood levels of heavy metals (like cadmium, mercury, lead) and essential metals (like chromium, iron, manganese, magnesium, copper) with the risk of metabolic syndrome (MetS).
  • - The analysis included 29 studies, revealing that higher levels of cadmium and mercury are associated with a greater risk of MetS, while increased chromium levels correlate with a reduced risk.
  • - The study concluded that certain heavy metals significantly increase the odds of developing MetS, while chromium acts protectively, highlighting the complex relationship between these metals and metabolic health.

Heart transplantation is a vital procedure for patients with end-stage heart failure, but it faces significant challenges, including graft dysfunction, rejection, and cardiac allograft vasculopathy (CAV), which can compromise long-term graft success. Research suggests that statin therapy may offer significant benefits to heart transplant recipients, such as improved long-term survival and reduced rates of graft rejection and mortality. The aim of this review is to thoroughly examine the recent literature on this topic since 2005.
