Chronic Left Ventricular Heart Failure
The effect of the vasodilator prazosin vs placebo on exercise duration until marked dyspnea, and on left ventricular function measured by echocardiography, was evaluated in a double-blind, randomized study in 24 patients with chronic left ventricular failure despite digitalis and diuretic therapy. Compared with the double-blind placebo, prazosin reduced resting systolic and diastolic blood pres...
متن کاملLeft ventricular failure produces profound lung remodeling and pulmonary hypertension in mice: heart failure causes severe lung disease.
Chronic left ventricular failure causes pulmonary congestion with increased lung weight and type 2 pulmonary hypertension. Understanding the molecular mechanisms for type 2 pulmonary hypertension and the development of novel treatments for this condition requires a robust experimental animal model and a good understanding of the nature of the resultant pulmonary remodeling. Here we demonstrate ...
متن کاملLung Changes in Shock
In the very beginning stage of the lung changes are Perivascular, capillary wall edema, thickening of the interstitial, lymph and vascular dilatation. In the late stage of the shock the following changes will occuree Microthromboses of the lung capillary, polynulcear infiltration into the interstitial, the existence of polynuclear in the alveoli, proliferation of interstitial mesenchyma,...
متن کاملLeft atrial function in diastolic heart failure.
BACKGROUND Abnormalities in left ventricular (LV) structure and function occur in patients with diastolic heart failure (DHF). The reasons for the transition from asymptomatic dysfunction to heart failure need better definition, including noninvasive measurements that can detect the transition. METHODS AND RESULTS In 64 patients undergoing right heart catheterization, simultaneous echocardiog...
متن کاملHeart failure and the lung.
Heart failure (HF) is a highly prevalent disease that leads to significant morbidity and mortality. There is increasing evidence that the symptoms of HF are exacerbated by its deleterious effects on lung function. HF appears to cause airway obstruction acutely and leads to impaired gas diffusing capacity and pulmonary hypertension in the longer term. It is postulated that this is the result of ...
