Pulmonary haemorrhage and extensive arterial thrombosis with anabolic steroid abuse.

Anabolic-androgenic steroids (AASs) are commonly implicated in thromboembolic events but rarely cause diffuse alveolar haemorrhage. We report the case of a Caucasian man in his late 40s who was consuming supratherapeutic doses of AAS and presented with shortness of breath and haemoptysis. Chest imaging showed bilateral patchy infiltrates in the lungs with diffuse blood throughout the airways on bronchoscopy. Extensive infectious and autoimmune workup were unremarkable. The patient then developed right foot ischaemia and was found to have extensive aortic and bilateral lower extremity arterial thrombosis. Anticoagulation was attempted despite haemoptysis. Thrombectomy procedures were unsuccessful and the patient eventually developed worsening rhabdomyolysis requiring intubation and bilateral amputation. His clinical condition continued to worsen and he passed away 10 days after admission. This case highlights the rare synchronous occurrence of two life-threatening complications secondary to anabolic steroid abuse which can pose a significant diagnostic and therapeutic challenge for clinicians.

Impact of Yoga on Cardiac Autonomic Function and Arrhythmias.

With the expanding integration of complementary and alternative medicine (CAM) practices in conjunction with modern medicine, yoga has quickly risen to being one of the most common CAM practices across the world. Despite widespread use of yoga, limited studies are available, particularly in the setting of dysrhythmia. Preliminary studies demonstrate promising results from integration of yoga as an adjunct to medical therapy for management of dysrhythmias. In this review, we discuss the role of autonomic nervous system in cardiac arrhythmia,interaction of yoga with autonomic tone and its subsequent impact on these disease states. The role of yoga in specific disease states, and potential future direction for studies assessing the role of yoga in dysrhythmia.

Implantable loop recorders for cardiac dysrhythmia monitoring.

Incorporation of technological advances in healthcare delivery has played a foundational role in development of modern healthcare. With the use of wireless transmission in conjunction with digitization of electrocardiography, continuous monitoring strategies have redefined our approach to dysrhythmia. These devices show promising results in evolving implantable loop recorder technology. In this review, we summarize the history of remote monitoring, indications for loop recorders, devices available, evidence for specific devices and anticipated studies.

Safety and efficacy of leadless pacemaker for cardioinhibitory vasovagal syncope.

BACKGROUND: Single-chamber leadless pacemakers (LPs) have been shown to be an effective alternative to conventional transvenous pacemakers (CTPs), but their benefit in the context of cardioinhibitory vasovagal syncope (CI-VVS) is unknown. OBJECTIVE: The purpose of this study was to evaluate the safety and efficacy of LP compared with dual-chamber CTP for CI-VVS. METHODS: We conducted a multicenter, retrospective study comparing patients who received LP or dual-chamber CTP for drug-refractory CI-VVS. CI-VVS was diagnosed clinically and supported by cardiac monitoring and head-up tilt table testing. The primary efficacy endpoint was freedom from syncope during follow-up. Secondary endpoints included device efficacy and safety estimated by device-related major and minor adverse events (AEs). RESULTS: Seventy-two patients (24 LP, 48 CTP; age 32 ± 5.5 years; 90% female; syncope frequency 7.6 ± 3.4 per year) were included. At 1 year, 91% of patients (22/24) in the LP group and 94% of patients (43/48) in the CTP group met the primary efficacy endpoint (P = .7). Device efficacy endpoint was met in 92% of the LP group and 98% of the CTP group (P = .2). Early major AEs occurred in 2 of 24 in the LP group and 3 of 48 in the CTP group (P = .4). Late major AEs occurred in 0 of 24 in the LP group and 2 of 48 in the CTP group (P = 1). CONCLUSION: In patients with CI-VVS, single-chamber LP demonstrated equivalent efficacy in reducing syncopal events compared to dual-chamber CTP, with a similar safety profile.
