Reference Values of Tissue Doppler Imaging and Pulsed Doppler Echocardiography for Analysis of Left Ventricular Diastolic Function in Healthy Adults

, 2010
To determine reference values for tissue Doppler imaging (TDI) and pulsed Doppler echocardiography for left ventricular diastolic function analysis in a healthy Brazilian adult population. Observations were based on a randomly selected healthy population

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Usefulness of color Doppler in the diagnosis of ventricular septal rupture after myocardial infarction

, 1990
Ten consecutive patients with ventricular septal rupture complicating acute myocardial infarction were studied by means of Doppler echocardiography (including two-dimensional, conventional and color Doppler techniques) and bedside right heart ...

Perivalvular Abscess of Tricuspid Valve: A Rare Complication of Infective Endocarditis [PDF]

Journal of Tehran University Heart Center, 2010
Infective endocarditis is a serious complication of intravenous (IV) drug abuse, with a reported mortality of 5 to 10%. A 21-year-old man, who was an intravenous drug abuser, presented with fever and dyspnea.

Echo-Doppler Features of Pulmonary Valve Endocarditis [PDF]

, 1989
Three patients with fever and pneumonitis were found to have pulmonary valve vegetations by echocardiography. Pulsed and color flow Doppler studies demonstrated mild to moderate pulmonary valve insufficiency in these patients.

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.

Multiscale four‐dimensional imaging of cardiac remodelling after myocardial infarction

The Journal of Physiology, EarlyView.
Abstract figure legend Multiscale 4D imaging framework for integrated phenotyping of post‐infarction remodelling. Myocardial infarction triggers dynamic changes across mechanical, haemodynamic and biological axes, progressing from acute injury and inflammation to extracellular matrix remodelling and scar maturation.

Asymptomatic Cardiotoxicity After High‐Dose Anthracycline Treatment in Sarcoma Patients Assessed by Biomarkers and Echocardiography

International Journal of Cancer, Volume 159, Issue 11, Page 2755-2765, 1 December 2026.
ABSTRACT Treatment of sarcoma includes high‐dose anthracyclines, which can cause cardiotoxicity. This study assesses the correlation of cardiac biomarkers and echocardiographic parameters on asymptomatic cardiotoxicity in sarcoma patients treated with anthracyclines.
