background : sleep apnea is accompanied by some cardiovascular complications. it has even been hypothesized that sleep apnea, itself, can induce some of these complications. given such controversies, we assessed the left ventricular mass index (lvmi) and systolic pulmonary artery pressure in patients with sleep apnea. methods: through convenience sampling, 56 patients with the obstructive sleep...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

The calculated systolic, diastolic and mean pulmonary artery pressure, the ratio of sizes right left ventricles heart, eccentricity index ventricle, systolic excursion fibrous ring tricuspid valve, movement myocardium at level valve area atrium are main echocardiographic indicators for assessing idiopathic similar forms hypertension according to current Russian, Eurasian European guidelines in ...

Aim. To evaluate the change in parameters of systolic and diastolic myocardial functions patients with severe obstructive sleep apnea (OSA) syndrome before after CPAP therapy.
 Materials methods. Forty eight OSA aged 4574 years were examined. All underwent questionnaires, echocardiography tissue Dopplerography, speckle-tracking echocardiography. At end three-month course therapy, re-examin...

Objective: Patients with single functional ventricles have a bad prognostic; most result in heart failure even after operation. The right heart bypass operations, except for right atrium and right ventricle connections, lack pulsatile flow and the volume returning to the common ventricle is low. To solve this problem, we tried to experimentally create a pulmonary ventricle which produces pulsat...

By its heat and continuous motion, the lung further concocts the blood brought to it through the arterylike vein [pulmonary artery], and renders it foamier, such as that [blood] already is which reaches the lung through the veinlike artery [pulmonary vein] from the left ventricle of the heart, since it has already been elaborated in both ventricles of the heart.

AMINOPHYLLINE (theophylline ethylenediamine) has been used traditionally in the treatment of bronchospasm associated with asthma, obstructive bronchitis, and emphysema, and its effect on reducing airway obstruction has been clearly shown.' The hemodynamic effects of this agent, however, have not been fully explored. Aminophylline has been shown to reduce the pulmonary artery pressure in patient...

The Chinese alligator (Alligator sinensis) belongs to the genus Alligator, which is a unique crocodile in China. In order study macroscopic structure of heart alligator, we performed detailed cardiac anatomy on five specimens. cranial mediastinum. It caudally involved by liver margins, and ventrally ribs, intercostal muscles, sternum dorsally lungs. wild typical four-chamber heart, with two (ri...

BACKGROUND There are limited data on the prevalence, pathophysiology, and management implications of pulmonary hypertension in patients with obstructive hypertrophic cardiomyopathy and advanced heart failure. METHODS AND RESULTS To assess the clinical significance of measured cardiopulmonary hemodynamics in hypertrophic cardiomyopathy patients with heart failure, we retrospectively assessed r...
