Frequency and Clinical Implications of Referrals to Heart Failure Among Patients with Peripartum Cardiomyopathy.

Peripartum cardiomyopathy (PPCM) is a rare but significant cause of new-onset heart failure (HF) during the peri- and post-partum periods. Advances in GDMT for HF with reduced ventricular function have led to substantial improvements in survival and quality of life, yet few studies examine the longitudinal care received by patients with PPCM. The aim of this research is to address this gap by retrospectively characterizing patients with PPCM across a multihospital health system and investigating the frequency of cardiology and HF specialty referrals. Understanding whether surveillance and medical management differ among patients referred to HF will help to underscore the importance of referring patients with PPCM to HF specialists for optimal care.

Investigating the time-lapsed effects of rigid cervical collars on the dimensions of the internal jugular vein.

Protocol advocates the use of rigid cervical collars (RCCs) in head trauma patients as they are at risk of concomitant cervical spine injury. Literature has shown RCCs to be a potential cause of venous outflow obstruction, changing internal jugular vein (IJV) cross-sectional area (CSA), and raising intracranial pressure (ICP). This study aims to investigate the effects of applying a RCC, for a period of four hours, on the dimensions of the IJV, in healthy participants. Seventeen participants (nine male, eight female) took part in this study. Circumference and CSAs of the IJV were measured bilaterally by a single observer using a GE LOGIQ e ultrasound system. Measurements were taken pre-RCC application, immediately after, every hour over four hours, and five minutes postcollar removal. The CSA of the IJV was 8.3 ±6.0 mm2 pre-RCC application. The CSA of the IJV doubled (18.92 ±10.55 mm2 ) after four hours and decreased back to 9.36 ±6.8 mm2 five minutes postcollar removal. The circumference of the IJV was 17.29 ±6.03 mm pre-RCC application, increasing to 20.34 ±5.59 mm by the end of the fourth hour and returning to 16.14 ±5.16 mm five minutes postcollar removal. Related-samples Friedman's ANOVA test showed statistically significant differences for both left and right CSAs and circumferences of the IJV measured across the four hours (P-value<0.05). Ultrasound assessment of CSA of the IJV may correlate with changes in ICP. Further studies may provide insight into the effects of collar design, and guide future trauma protocol to minimize intracranial pressure fluctuations. Clin.

Aortic Thrombosis and Ischemic Stroke With Hemorrhagic Conversion in a Patient With Remote COVID-19 Infection: A Treatment Dilemma.

Coronavirus disease 2019 (COVID-19) is primarily known to affect the lungs; however, several studies indicate that it can be a multisystem disease. There is documentation detailing different sequelae of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Patients affected with this virus have been seen to develop a hypercoagulable state leading to systemic thrombosis in some cases or embolism leading to catastrophic outcomes in others. Data regarding anticoagulation in these patients is limited. Further research needs to be carried out for management and prophylaxis for patients with COVID-19 at risk of aortic thrombosis.  We present a case of a middle-aged man with multiple comorbidities and remote COVID-19 infection who came to the emergency room with signs and symptoms worrisome for a cerebrovascular accident (CVA). Brain imaging revealed multiple cortical infarcts suggestive of a cardioembolic etiology. During his hospitalization, he underwent a transesophageal echocardiogram (TEE) that showed a 1x1 cm mobile thrombus in the distal descending aorta. Laboratory workup was negative for any hypercoagulable condition; it was thought that this patient might have a hypercoagulable state post-COVID-19 infection. After a thorough risk vs. benefit discussion, patient was started on apixaban. He remains alive and is doing well in a recent follow-up in our clinic.
