Arterial wave reflection in heart failure.

PATHOPHYSIOLOGY AND NATURAL HISTORY CONGESTIVE HEART FAILURE Arterial wave reflection in heart failure

Arterial wave reflection may adversely influence both left ventricular afterload and ejection performance. Therefore, using multisensor catheter manometers, we derived wave reflection indexes from ascending aortic pressure and velocity recordings in 17 subjects with clinical heart failure secondary to idiopathic dilated cardiomyopathy and 11 control subjects free of detectable cardiovascular di...

Reduced systolic wave generation and increased peripheral wave reflection in chronic heart failure.

In human heart failure the role of wave generation by the ventricle and wave reflection by the vasculature is contentious. The aim of this study was to compare wave generation and reflection in normal subjects with patients with stable compensated heart failure. Twenty-nine normal subjects and 67 patients with heart failure (New York Heart Association class II or III) were studied by noninvasiv...

Uncertainties in estimating the site of arterial wave reflection.

Heritability and a genome-wide linkage scan for arterial stiffness, wave reflection, and mean arterial pressure: the Framingham Heart Study.

BACKGROUND Arterial stiffness and mean arterial pressure variably contribute to systolic hypertension and increased cardiovascular risk. However, few prior community-based studies have evaluated the genetics of arterial stiffness and separate mean and pulsatile components of blood pressure. METHODS AND RESULTS Using arterial tonometry, we evaluated heritability and linkage of forward and refl...
