RESUMEN
PURPOSE OF REVIEW: Sleep is an important component of cardiovascular (CV) health. This review summarizes the complex relationship between sleep and CV disease (CVD). Additionally, we describe the data supporting the treatment of sleep disturbances in preventing and treating CVD. RECENT FINDINGS: Recent guidelines recommend screening for obstructive sleep apnea in patients with atrial fibrillation. New data continues to demonstrate the importance of sleep quality and duration for CV health. There is a complex bidirectional relationship between sleep health and CVD. Sleep disturbances have systemic effects that contribute to the development of CVD, including hypertension, coronary artery disease, heart failure, and arrhythmias. Additionally, CVD contributes to the development of sleep disturbances. However, more data are needed to support the role of screening for and treatment of sleep disorders for the prevention of CVD.

Triglycerides play a crucial role in the efficient storage of energy in the body. Mild and moderate hypertriglyceridemia (HTG) is a heterogeneous disorder with significant association with atherosclerotic cardiovascular disease (ASCVD), including myocardial infarction, ischemic stroke, and peripheral artery disease and represents an important component of the residual ASCVD risk in statin treated patients despite optimal low-density lipoprotein cholesterol reduction. Individuals with severe HTG (>1,000 mg/dL) rarely develop atherosclerosis but have an incremental incidence of acute pancreatitis with significant morbidity and mortality. HTG can occur from a combination of genetic (both mono and polygenic) and environmental factors including poor diet, low physical activity, obesity, medications, and diseases like insulin resistance and other endocrine pathologies. HTG represents a potential target for ASCVD risk and pancreatitis risk reduction, however data on ASCVD reduction by treating HTG is still lacking and HTG-associated acute pancreatitis occurs too rarely to effectively demonstrate treatment benefit. In this review, we address the key aspects of HTG pathophysiology and examine the mechanisms and background of current and emerging therapies in the management of HTG.
RESUMEN
Introduction Cardiology is a complex discipline that requires mastery of key principles and the ability to apply them in varied clinical scenarios, which may be challenging to teach in the traditional lecture-based format. The purpose of this educational intervention was to evaluate the effect of a flipped classroom model on knowledge base and attitudes towards high-yield cardiology concepts in third and fourth-year medical students at our institution. Methods An invitation to this optional course was sent to third and fourth-year medical students at the Icahn School of Medicine at Mount Sinai. Interested students were sent a document providing optional pre-course self-directed educational materials designed to take one hour to review. The materials included videos, graphics, and short sections of articles related to heart failure (HF), acute coronary syndrome (ACS), and tachyarrhythmias (TA). Students were then scheduled for a thirty-minute small-group session with a clinician, during which they reviewed the diagnosis and management of HF, ACS, and TA on an online video conference platform. Anonymous pre- and post-course assessments to measure knowledge and confidence were collected. Results Twenty-one students completed the pre-course assessment, and 19 students completed the post-course assessment. Seventy-nine percent of the students reported completion of at least half of the self-directed pre-work. The average score on the knowledge assessment rose from 42% to 71% after the course (p<0.001). After the course, 18 (95%) felt comfortable contributing to the management of a case of HF, 16 (84%) a case of ACS, and 13 (68%) a case of TA. Conclusion Knowledge assessment scores and learner self-confidence with the management of HF, ACS, and TA rose significantly after undergraduate medical education students completed this flipped classroom training. This exploratory study showed that the flipped classroom model with small group sessions can be a well-received model for medical student cardiology education among a self-motivated group of learners, though further analysis with a larger learner cohort is needed.
