Hemodynamic, hormonal, and renal effects of (pro)renin receptor blockade in experimental heart failure. (2/8)

BACKGROUND: The (pro)renin receptor (P)RR is implicated in blood pressure regulation and the pathophysiology of heart failure (HF). The effects of (P)RR blockade in HF have not been previously investigated. METHODS AND RESULTS: Eight sheep received on 2 separate days a vehicle control and incremental intravenous boluses of a (P)RR antagonist, ovine handle region peptide (HRP) (1, 5, and 25 mg at 90-minute intervals), both before (normal) and after induction of HF by rapid left ventricular pacing. In normal sheep, HRP reduced heart rate (P<0.001) and hematocrit (P=0.019) compared with time-matched control data, without significantly affecting any other hemodynamic, hormonal, or renal variables. In sheep with HF, HRP treatment induced progressive falls in mean arterial pressure (P<0.001) in association with decreases in left atrial pressure (P<0.001), peripheral resistance (P=0.014), and hematocrit (P<0.001). Cardiac contractility tended to decline (P=0.096), whereas cardiac output was unaltered. HRP administration produced a dose-dependent decrease in plasma renin activity (P=0.004), with similar trends observed for plasma angiotensin II and aldosterone (P=0.093 and P=0.088, respectively). Circulating natriuretic peptides, endothelin-1, and catecholamine levels were unchanged. HRP also induced a reduction in plasma sodium concentrations relative to control (P=0.024), a natriuresis (P=0.046), and a tendency for creatinine excretion and clearance to improve. CONCLUSIONS: (P)RR antagonism in experimental HF resulted in cardiovascular and renal benefits in association with inhibition of the renin-angiotensin-aldosterone system. These findings suggest that (P)RR contributes to pressure/volume regulation in HF and identifies the receptor as a potential therapeutic target in this disease.  (+info)

Pulmonary circulation at exercise. (4/8)

The pulmonary circulation is a high-flow and low-pressure circuit, with an average resistance of 1 mmHg/min/L in young adults, increasing to 2.5 mmHg/min/L over four to six decades of life. Pulmonary vascular mechanics at exercise are best described by distensible models. Exercise does not appear to affect the time constant of the pulmonary circulation or the longitudinal distribution of resistances. Very high flows are associated with high capillary pressures, up to a 20 to 25 mmHg threshold associated with interstitial lung edema and altered ventilation/perfusion relationships. Pulmonary artery pressures of 40 to 50 mmHg, which can be achieved at maximal exercise, may correspond to the extreme of tolerable right ventricular afterload. Distension of capillaries that decrease resistance may be of adaptative value during exercise, but this is limited by hypoxemia from altered diffusion/perfusion relationships. Exercise in hypoxia is associated with higher pulmonary vascular pressures and lower maximal cardiac output, with increased likelihood of right ventricular function limitation and altered gas exchange by interstitial lung edema. Pharmacological interventions aimed at the reduction of pulmonary vascular tone have little effect on pulmonary vascular pressure-flow relationships in normoxia, but may decrease resistance in hypoxia, unloading the right ventricle and thereby improving exercise capacity. Exercise in patients with pulmonary hypertension is associated with sharp increases in pulmonary artery pressure and a right ventricular limitation of aerobic capacity. Exercise stress testing to determine multipoint pulmonary vascular pressures-flow relationships may uncover early stage pulmonary vascular disease.  (+info)

The radius of the pulmonary arteries and of the descending thoracic aorta in man was measured by angiographic techniques. Simultaneously with angiocardiography, pressure measurements were carried out, permitting calculation of radius-pressure (ΔR/ΔP) relationships. The results obtained by this method are similar to those obtained by other methods in which the vessel radius was measured more directly.. ...

Noninvasive pulmonary artery systolic pressure (PASP) is calculated by summing the right ventricular systolic pressure obtained from Doppler velocity of regurgitant flow through the tricuspid valve and the right atrial (RA) pressure. The RA pressure is generally assumed from different formulas. An accurate KA pressure estimation will add precision to PASP calculation. One of the methods to estimate RA pressure is the inferior vena cava collapsibility index (IVCCI). In 45 patients referred for right heart catheterization, the authors tested a formula for the calculation of PASP based on the estimation of RA pressure from IVCCI and compared this method with two other formulas. ...
by PWeekly , Aug 9, 2012. New research was presented at ASE 2012, the American Society of Echocardiographys 23rd Annual Scientific Sessions, from June 30 to July 3 in Maryland. The features below highlight just some of the studies that emerged from the conference. Echocardiograms for Diagnosing Pulmonary Hypertension The Particulars: Patients with stable heart failure who have high pulmonary artery systolic pressure are at increased risk for adverse outcomes. A reliable method is needed for measuring pulmonary artery systolic pressure in this patient population. Data Breakdown: Emory University researchers used echocardiography to diagnose pulmonary hypertension- defined as pulmonary artery systolic pressure higher than 45 mm Hg-in stable outpatients with heart failure. Echocardiography was found to strongly predict higher risk of clinical events. The testing also helped determine which patients would have higher hospitalization rates. Take Home Pearl: Pulmonary artery systolic pressure as ...

We read with great interest the article by MacDonald and Struthers (1) in a recent issue of the Journal.The article reports that potassium depletion is important in the pathogenesis of cardiovascular disease and sudden cardiac death. The authors suggest that avoiding hypokalemia is beneficial in several cardiovascular disease states, including acute myocardial infarction, heart failure, and hypertension. The data linking hypokalemia with arrhythmia and cardiac arrest in acute myocardial infarction are fairly strong (2-4).. We want to add atrial fibrillation (AF) after cardiac surgery to the list of cardiovascular diseases where electrolyte imbalance may play an important pathogenetic role. Although the etiology of AF after heart surgery is incompletely understood, stimuli and triggers such as pre-existing structural changes of the atria related to hypertension, mechanical damage, volume overload, age, intraoperative atrial ischemia, and pericardial lesions are thought to play a role in the ...

N2 - The application of three-dimensional (3D) time-of-flight (TOF) magnetic resonance (MR) angiographic techniques to the vasculature of the abdomen and thorax has not, to the authors knowledge, been previously reported; this is possibly due to the large amount of physiologic motion in these regions along with the anticipated sensitivity of the 3D acquisition scheme to image degradation caused by motion artifact. The authors describe an asymmetric short-echo velocity-compensated 3D TOF technique that minimized the effects of physiologic motion on image quality and provided rapid high-resolution 3D MR arteriograms of the abdomen and thorax. Contiguous 3D volumes were often combined to provide sufficient anatomic coverage. Benefits include high spatial resolution and minimization of signal loss; ...
