Coronary haemodynamics in left ventricular hypertrophy.
BACKGROUND Left ventricular hypertrophy is associated with an increased risk of cardiovascular morbidity and mortality. Previous studies have shown that patients with left ventricular hypertrophy develop electrocardiographic changes and left ventricular dysfunction during acute hypotension, and suggest that the lower end of autoregulation may be shifted upwards. AIM To measure coronary blood ...
متن کاملAssessment of left ventricular performance during laparoscopy.
OBJECTIVES Cardiovascular changes during laparoscopic surgery have been described in several studies. Pneumoperitoneum effects on cardiac performance instead have not been much investigated and are less known. The carbon dioxide insufflation necessary in order to perform laparoscopic procedures represents a higher force against which the myocardial fibers must shorten during ventricular contrac...
متن کاملHypertension, arterial haemodynamics and left ventricular disease: historical observations.
The importance of arterial stiffening in the pathogenesis of cardiovascular disease has been gaining acceptance in recent years but is still widely overlooked, with the present preoccupation being atherothrombosis. Arteriosclerosis is a result of a combination of endothelial dysfunction and structural abnormalities of the media of conduit arteries (in contrast to atherosclerosis which is an int...
متن کاملPhysiological relationships between central vascular haemodynamics and left ventricular structure.
Left ventricular hypertrophy is an independent cardiovascular risk factor. In hypertensives, the pattern of hypertrophy is influenced by central haemodynamic characteristics. Central haemodynamics may also determine physiological differences in left ventricular structure and predispose to particular responses of the left ventricle to pathological increases in load. M-mode echocardiography was u...
متن کاملCerebral haemodynamics during experimental intracranial hypertension.
Intracranial hypertension is a common final pathway in many acute neurological conditions. However, the cerebral haemodynamic response to acute intracranial hypertension is poorly understood. We assessed cerebral haemodynamics (arterial blood pressure, intracranial pressure, laser Doppler flowmetry, basilar artery Doppler flow velocity, and vascular wall tension) in 27 basilar artery-dependent ...
