How to interpret a cardiorespiratory fitness assessment - Key measures that provide the best picture of health, disease status and prognosis.

Graded exercise testing is a widely accepted tool for revealing cardiac ischemia and/or arrhythmias in clinical settings. Cardiopulmonary exercise testing (CPET) measures expired gases during a graded exercise test making it a versatile tool that helps reveal underlying physiologic abnormalities that are in many cases only present with exertion. It also characterizes one's health status and clinical trajectory, informs the therapeutic plan, evaluates the efficacy of therapy, and provides submaximal and maximal information that can be used to tailor an exercise intervention.

A Cyclist on a Tricyclic: Exercise Intolerance Due to Chronotropic Incompetence.

Depression in athletes is prevalent, and antidepressant treatment may have a cardiovascular impact. We present a case, documented by serial exercise testing, of exertional intolerance due to chronotropic incompetence associated with tricyclic antidepressant use. This case underscores the importance of understanding the mechanism of action and side effects of antidepressants.

Racial disparities in inferior vena cava filter use in metabolic and bariatric surgery patients: Nationwide insights from the MBSAQIP database.

Background: Prophylactic inferior vena cava (IVC) filter use in bariatric surgery patients is a physician- and patient-dependent practice pattern with unclear safety and efficacy. Factors that mediate physicians' decisions for IVC filter placement preoperatively remain unclear. The role of race in decision-making also remains unclear.

Prophylactic Inferior Vena Cava Filters Prior to Bariatric Surgery: Insights From the National Inpatient Sample.

Objectives: The aim of this study was to determine in-hospital mortality, post-surgical thromboembolic events, and health care costs associated with the placement of prophylactic inferior vena cava filters (IVCFs) prior to bariatric surgery.

Background: The role of prophylactic IVCFs prior to bariatric surgery is controversial, and the nationwide clinical outcomes associated with this practice are unknown.

Methods: This observational study used the National Inpatient Sample database to identify obese patients who underwent bariatric surgery from January 2005 to September 2015.

Association Between Contemporary Trends in Inferior Vena Cava Filter Placement and the 2010 US Food and Drug Administration Advisory.

This study uses the National Inpatient Sample database to assess the association between rates of inferior vena cava filter placement in the United States and the 2010 US FDA device safety warning.

Genetics of coronary artery disease - a clinician's perspective.

Coronary artery disease (CAD) is the major cause of fatality and disability among all cardiovascular diseases (CVD). Intricate interactions of genes and environment dictate the outcomes of CAD. Technological advances in the different fields of genetics including linkage studies (LS), candidate gene studies (CGS) and genome-wide association studies (GWA studies) have augmented the knowledge of pathogenesis of CAD.
