What role does the right side of the heart play in circulation? [PDF]

, 2006
Right ventricular failure (RVF) is an underestimated problem in intensive care. This review explores the physiology and pathophysiology of right ventricular function and the pulmonary circulation.

O bloqueio do sistema renina-angiotensina atenua a remodelação cardíaca de ratos submetidos a estenose aórtica Blockade of renin-angiotensin system attenuates cardiac remodeling in rats undergoing aortic stenosis

Arquivos Brasileiros de Cardiologia, 2005
OBJETIVO: Avaliar o papel do bloqueador dos receptores AT1 e do inibidor da enzima conversora da angiotensina na remodelação cardíaca induzida por estenose aórtica em ratos.

Right ventricular volumes and function in thalassemia major patients in the absence of myocardial iron overload [PDF]

, 2010
Aim: We aimed to define reference ranges for right ventricular (RV) volumes, ejection fraction (EF) in thalassemia major patients (TM) without myocardial iron overload.Methods and results: RV volumes, EF and mass were measured in 80 TM patients who had ...

Perfil nutricional e cardiovascular de ratos normotensos e hipertensos sob dieta hiperlipídica Perfil nutricional y cardiovascular de ratas normotensas e hipertensos bajo dieta hiperlipídica Nutritional and cardiovascular profiles of normotensive and hypertensive rats kept on a high fat diet

Arquivos Brasileiros de Cardiologia, 2009
FUNDAMENTO: Embora dietas hiperlipídicas (DH) promovam distúrbios nutricionais e cardíacos, poucos estudos avaliaram sua influência em ratos normotensos Wistar-Kyoto (WKY) e espontaneamente hipertensos (SHR).

Improved ventricular function during inhalation of PGI(2) aerosol partly relies on enhanced myocardial contractility [PDF]

, 2005
Inhaled prostacyclin (PGI(2)) aerosol induces selective pulmonary vasodilation. Further, it improves right ventricular ( RV) function, which may largely rely on pulmonary vasodilation, but also on enhanced myocardial contractility.

Aortic calcification and femoral bone density are independently associated with left ventricular mass in patients with chronic kidney disease [PDF]

, 2012
Background Vascular calcification and reduced bone density are prevalent in chronic kidney disease and linked to increased cardiovascular risk. The mechanism is unknown.

How to achieve balloon stability in aortic valvuloplasty using rapid ventricular pacing [PDF]

, 2004
Balloon aortic valvuloplasty is now the treatment of choice for congenital aortic stenosis. Balloon stability may be difficult to achieve and this may result in a suboptimal result or even valve damage.

The self-maintaining nature of ventricular fibrillation : contribution of L-type Ca²+ channels and Na+/Ca²+ exchange to cardiomyocyte Ca²+ overload in ventricular fibrillation : surface fluorescence study in isolated perfused rat hearts [PDF]

, 2004
Approximately 40% of all deaths in Switzerland are due to cardiovascular diseases.1 An important part of these deaths happen because of life-threatening cardiac arrhythmias.
