https://www.selleckchem.com/products/pq912.html The black widow spider (BWS) is a venomous spider whose bite can cause various clinical conditions that range from local damage to serious systemic complications, including death. Cases of myocarditis following a BWS bite are rare but they can be fatal on occasion. However, the prognostic significance of the bite and presentation of myocarditis is unknown. Our case involved a 50-year-old man who presented with myocarditis after being bitten by a BWS and subsequently admitted to the intensive care unit for cardiac monitoring. During the hospital stay, he showed worsening signs on both the electrocardiographic and echocardiographic evaluations despite therapeutic success. Subsequent cardiac magnetic resonance and coronary angiography investigations showed no significant alterations; blood and instrumental test results slowly improved, and the patient was discharged home after 12 days of hospitalization without complications. This case illustrates that acute myocarditis, although an infrequent complication of BWS bite, has the potential to be lethal. The correct diagnosis, which is not always easy to formulate, is important to identify those patients who can benefit from careful monitoring and specific therapies aimed at reducing the risk of life.Introduction This study was designed to gain insight into the treatment experiences and expectations of patients with atrial fibrillation (AF) who were treated with vitamin K antagonists (VKA) or recently switched from VKA treatment to direct oral anticoagulant (DOAC) therapy. Little is known about the perceptions and expectations of patients with AF who are being prescribed oral anticoagulants (OACs), leading to different expectations of patient and doctor of their respective roles in disease management between the doctor [general practitioner (GP) or cardiologist] and patient on their respective roles in disease management.
