Progressive breathlessness in an Afro Caribbean hypertensive subject.
The sensitivity and specificity of structural assessment of the heart by echocardiography in black hypertensive patients presenting with symptoms of heart failure is often incomplete. Cardiovascular magnetic resonance, mainly by virtue of its ability to characterize myocardial tissue composition, may be of value in differentiating some of the common pathologies noninvasively. We present an ...
متن کاملBreathlessness in hospitalised adult patients.
Dyspnoea is defined as a sensation of difficult breathing. It is common in hospitalised patients and is often a harbinger of serious and potentially fatal pathology. The pathophysiology of dyspnoea involves complex interactions between peripheral and central receptors and cognition. Given the myriad causes of dyspnoea, a systematic approach to diagnosis is important. A good history and systemic...
متن کاملLack of effect of inhaled morphine on exercise-induced breathlessness in chronic obstructive pulmonary disease.
BACKGROUND Inhaled nebulised morphine may reduce breathlessness in patients with lung disease, although the results of controlled trials are conflicting. A direct action of morphine on the lung has been postulated. This study aimed to investigate whether nebulised morphine reduced exercise-induced breathlessness in patients with chronic obstructive pulmonary disease (COPD) and to determine if t...
متن کاملEndogenous endothelin-1 limits exercise-induced vasodilation in hypertensive humans.
Essential hypertension is a common disorder, associated with increased endothelin-1-mediated vasoconstrictor tone at rest. We hypothesized that increased vasoconstrictor activity of endothelin-1 might explain why the normal decrease in peripheral vascular resistance in response to exercise is attenuated in hypertensive patients. Therefore, we investigated the effect of endothelin A (ET(A)) rece...
متن کاملVoluntary physical exercise-induced vascular effects in spontaneously hypertensive rats.
Forced training has been shown to have beneficial vascular effects in various animal exercise models. In the present study, we explored possible physiological and molecular effects of voluntary physical exercise on various vascular beds. SHR (spontaneously hypertensive rats) performed voluntary exercise for 5 weeks in a computerized wheel cage facility. Ex vivo myograph studies revealed an incr...
