Patients with diabetes mellitus (DM) frequently present reduced exercise capacity. We aimed to explore the extent to which peripheral extraction relates to exercise capacity in asymptomatic patients with DM. We prospectively enrolled 98 asymptomatic patients with type-2 DM (mean age of 59 ± 11 years and 56% male sex), and compared with 31 age, sex and body mass index-matched normoglycemic controls. ⋯ A cluster analysis found left ventricular longitudinal strain, E/e', relative wall thickness and peak VO2 in different clusters. In conclusion, impaired peripheral extraction may contribute to reduced peak VO2in asymptomatic patients with DM. Furthermore, a cluster analysis suggests that cardiopulmonary exercise testing and echocardiography may be complementary for defining subclinical heart failure in patients with DM.

REMOVED: The Cardiovascular Physical Examination - Is It Still Relevant?
Advances in technology have reshaped the practice of medicine. These changes have greatly benefited our patients. However, in the setting of these advances, the importance of basic clinical tools is more pertinent than ever. ⋯ We aim to investigate current competency and proficiency, proposals for change in teaching curriculums, and the relationship with technology such as hand-held echocardiography. A skillful exam provides both emotional and intellectual satisfaction. It may be a lost art but it is well worth the effort to restore.

Comparative Study
Transcatheter Versus Surgical Aortic Valve Replacement in the United States (From the Nationwide Readmission Database).
Clinical outcomes of transcatheter aortic valve implantation (TAVI) have significantly improved with the accumulation of operator and institution experience as well as the wide use of newer generation devices. There is limited data on TAVI outcomes compared with surgical aortic valve replacement (SAVR) in contemporary practice in the United States. We queried the 2018 Nationwide Readmission Database of the United States. ⋯ S. dollars) (all p values < 0.001). In-hospital mortality was also lower in TAVI compared with isolated SAVR. TAVI was performed more frequently than SAVR in 2018 in the United States with lower in-hospital mortality of TAVI compared with both SAVR and isolated SAVR.

Chronic pressure-overload induces right ventricular (RV) adaptation to maintain RV-pulmonary arterial (PA) coupling. RV remodeling is frequently associated with secondary tricuspid regurgitation (TR) which may accelerate uncoupling. Our aim is to determine whether the non-invasive analysis of RV-PA coupling could improve risk stratification in patients with secondary TR. ⋯ The cumulative 5-year survival rate was lower in patients with RV-PA uncoupling compared to their counterparts (37% vs 64%, p < 0.001). After correcting for potential confounders, RV-PA uncoupling was the only echocardiographic parameter independently associated with all-cause mortality (HR 1.462; 95% CI 1.192 to 1.793; p < 0.001). In conclusion, RV-PA uncoupling in patients with secondary TR is independently associated with poor prognosis and may improve risk stratification.
