Ratio between right ventricular longitudinal strain and pulmonary arterial systolic pressure: A novel prognostic parameter in patients with severe tricuspid regurgitation.

Background: In terms of pathophysiology, tricuspid regurgitation (TR), right ventricular function and pulmonary artery pressure are linked to each other. Our aim was to analyze whether the echocardiography-derived right ventricular free wall longitudinal strain/pulmonary artery systolic pressures (RVFWLS/PASP) ratio can improve risk stratification in patients with severe tricuspid regurgitation (TR).

Methods: In this single-center retrospective study, 250 consecutive patients with severe TR were enrolled from December 2015 to December 2018.

The 24-hour rhythm of blood pressure differs from that of leg hemodynamics in orthotopic heart transplant recipients.

Background: This study was aimed at investigating whether a circadian rhythm of peripheral resistance exists in patients with orthotopic cardiac transplantation (OCT) and whether it parallels that of blood pressure (BP).

Methods: BP and leg flow and resistance (plethysmography) were monitored for 24 hours in 13 denervated OCT recipients and 13 control patients with native heart, matched for casual blood pressure.

Results: On the basis of BP trend, control patients showed a BP reduction during sleep, whereas OCT recipients did not.

Impaired glucose tolerance and its co-variates among 2079 non-diabetic elderly subjects. Ten-year mortality and morbidity in the CASTEL study. CArdiovascular STudy in the ELderly.

This study evaluated the role of impaired glucose tolerance (IGT) as a risk factor in a general population of 2079 non-diabetic elderly subjects. The 10-year cardiovascular morbidity was similar in normal and IGT subjects. Mortality was greater in IGT, but the Cox equations of the hazard rate were different in younger and older subjects: age, sex, lung function (forced expiratory volume in 1 s, FEV1), serum uric acid, IGT and proteinuria were predictors of overall mortality in the age class 65-79 years, while only the first 4 were associated with cardiovascular mortality.

24 h rhythm of blood pressure and forearm peripheral resistance in normotensive and hypertensive subjects confined to bed.

Objectives: To define whether a diurnal rhythm of peripheral resistance exists in normotensive and hypertensive subjects, has any relationship with that of blood pressure and differs in dipper and non-dipper hypertensives.

Design And Methods: Forty-three subjects (13 normotensives and 30 mild-to-moderate essential hypertensives) confined for 24 h to bed were included. Blood pressure was recorded for 22 h at 15 min intervals, plethysmographic forearm flow was simultaneously measured and forearm resistance calculated.
