Contralateral differences in ankle SBP and pulse wave velocity: associations with incident heart failure and mortality.

Background: Contralateral differences in brachial SBP are indicative of underlaying cardiovascular issues.

Objectives: To examine the association of contralateral differences in ankle SBP, brachial-ankle pulse wave velocity (baPWV), and heart-ankle pulse wave velocity (haPWV) with incident heart failure and all-cause and cardiovascular mortality.

Methods: Cox proportional-hazards models were used to calculate hazard ratios and 95% confidence intervals (95% CIs) in 5077 participants (75 ± 5 years) of the Atherosclerosis Risk in Communities study.

Effectiveness of different recovery postures during high-intensity interval training.

Background: High-intensity interval training (HIIT) has become a very popular mode of exercise practiced by the elite as well as recreationally active adults. The aim of this study was to evaluate the effects of four recovery postures that are typically used by exercisers on recovery rate and performance in subsequent bouts of HIIT.

Methods: Sixteen young, healthy adults performed four HIIT trials with randomized recovery postures.

Estimated pulse wave velocity and incident heart failure and its subtypes: Findings from the multi-ethnic study of atherosclerosis.

Unlabelled: Age-associated increase in aortic stiffness, measured as carotid-femoral pulse wave velocity (PWV), is an important effector of cardiac damage and heart failure (HF). Pulse wave velocity estimated from age and blood pressure (ePWV) is emerging as a useful proxy of vascular aging and subsequent cardiovascular disease risk. We examined the association of ePWV with incident HF and its subtypes in a large community sample of 6814 middle-aged and older adults from the Multi-Ethnic Study of Atherosclerosis (MESA).

Arterial stiffness and contralateral differences in blood pressure: The Atherosclerosis Risk in Communities (ARIC) study.

A large interarm difference in brachial systolic blood pressure (SBP) (≥10 or ≥15 mmHg) is strongly associated with elevated cardiovascular events and mortality. Evidence demonstrating whether such contralateral differences in SBP occur in ankle blood pressure and its association with arterial stiffness is scarce. The aims of this study were to characterize arm and ankle contralateral SBP differences in a sample of community-dwelling older adults (5077), and to determine whether this difference is associated with arterial stiffness assessed by pulse wave velocity (PWV) between the heart and ankle (haPWV), femoral artery and ankle (faPWV), and brachial artery and ankle (baPWV) in the right and left sides.

Total brachial artery reactivity and incident heart failure and heart failure subtypes: multi-ethnic study of atherosclerosis.

Endothelial dysfunction may be a phenotypic expression of heart failure (HF). Total brachial artery reactivity (TBAR) is a non-invasive measurement of endothelial function that has been associated with increased risk of cardiovascular outcomes. Limited information is currently available on the impact of TBAR on incident HF and its subtypes.
