Thrombotic thrombocytopenic purpura (TTP) is a rare and potentially devastating blood disorder depicted by thrombocytopenia, fever, widespread small vessel hemolytic anemia, and neurological symptoms. The involvement of the renal and neurological systems is frequently reported in TTP; however, TTP-induced acute coronary syndrome is not widely reported. We describe a case of myocardial infarction induced by TTP in a patient who presented with the typical manifestation of acute coronary syndrome. Echocardiogram revealed a myocardial injury, and detailed investigations revealed increased levels of troponin I, lactate dehydrogenase, diminished levels of haptoglobin and von Willebrand factor-cleaving protease, and schistocytes on peripheral smear, suggestive of TTP-induced myocardial infarction. His condition was stabilized after commencing plasmapheresis, steroids, and rituximab. The initial steps in the management of this patient involve the prompt administration of steroids and the urgent start of plasmapheresis to increase platelet count.
Introduction: The outcomes of Catheter Ablation (CA) and antiarrhythmic drugs (AAD) as the first-line treatment of paroxysmal Atrial Fibrillation (AF) are unclear. The current systematic review reports the evidence on efficacy outcomes of Radiofrequency Ablation (RFA) versus antiarrhythmic drugs (AAD) among these patients.
Methods: Three databases, including PubMed, Cochrane, and Google Scholar, were searched by three independent reviewers to identify relevant randomized control trials (RCTs).
Results: A total of 1,145 patients across five studies were assessed in this systematic review. Among these patients, 577 were randomized to receive ablation, and 568 were randomized to receive AAD. The recurrence rate was significantly higher among patients who received AAD at 1-year and 2-year follow-ups. The health-related quality of life (HR-QoL) was significantly better in the patients who received ablation therapy. The incidence of serious adverse events was 14 (6.4%) in the ablation group and 9 (4.3%) in the AAD group.
Conclusion: CA seems promising for managing AF in terms of any AF recurrence, hospitalization, and quality of life. There was no increase in side effects compared to AAD.
Exercise is widely considered beneficial for cardiovascular health. However, on rare occasions, athletes experience sudden cardiac death without any preceding symptoms. The devastating nature of these events necessitates us to understand the underlying causes. In younger athletes (age <35), the underlying causes are usually hereditary/genetic, whereas in older athletes (age >35), coronary artery disease is prevalent. Sudden cardiac death in athletes can occur regardless of the presence of any structural abnormality in the heart. Despite divergence between guidelines, the majority of cardiology societies recommend at least taking a comprehensive history and performing physical examinations for initial screening for all athletes. This article reviews the consensuses and controversies regarding the incidence, causes, and prevention of sudden cardiac death in athletes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
