abstract background: hypertension in pregnancy is one of the prevalent disorders resulting in maternal death. the aim of this study was to investigate the effect of stretching exercise and walking on changes of blood pressure in nulliparous women during pregnancy. materials and methods: this was a quasi-experimental trial that consisted three groups of women who took part in pre- and post-tests...

A transducer tipped catheter and simple recording system were used for the continuous measurement of ambulatory pulmonary artery pressure. The pulmonary artery pressure was recorded on a miniaturised tape recorder and replayed via an optical writer. Pulmonary arterial systolic and diastolic pressures can be analysed on a beat to beat basis. Continuous ambulatory monitoring was performed for a t...

The GUIDE-HF team1 should be congratulated on attempting to master congestion, a key driver of symptoms, signs, and progression heart failure. Controlling congestion is associated with an excellent prognosis,2 consideration for new universal definition failure.3 Symptoms signs are late, subjective, insensitive measures compared blood biomarkers, ultrasound, haemodynamics.3,4 Raised (>15 mm Hg) ...

Chronic right ventricular pressure overload is associated with left ventricular diastolic dysfunction. Whether or not an abrupt reduction in pulmonary artery pressure in patients with chronic pulmonary hypertension results in early improvement of left ventricular diastolic function is unknown. To assess this, the Doppler indexes of left ventricular diastolic function and echocardiographic measu...

Ten patients with chronic obstructive pulmonary disease without complicating cor pulmonale were studied by right and left heart catheterization. Respiratory and haemodynamic observations were made during a control period and during the infusion of phentolamine. Phentolamine produced a significant reduction in mean pulmonary artery pressure from I8 8 mmHg to I3 I mmHg, right ventricular end-dias...

BACKGROUND Left ventricular diastolic dysfunction, with secondary atrial pressure elevation, is a well-known concept. On the contrary, effect of left atrial compliance on pulmonary pressure is rarely considered. CASE PRESENTATION We report the echocardiographic case of a 9-year-old child who presented severe rheumatic mitral valve regurgitation with a giant left atrium, in contrast to a norma...

Hypertension is a risk factor for coronary artery disease. Recent genome-wide association studies have identified 30 genetic variants associated with higher blood pressure at genome-wide significance (P<5 × 10(-8)). If elevated blood pressure is a causative factor for coronary artery disease, these variants should also increase coronary artery disease risk. Analyzing genome-wide association dat...

BACKGROUND Dilated cardiomyopathy and ischaemic heart disease can both lead to right ventricular (RV) dysfunction. Direct comparisons of the two entities regarding RV size and function using state-of-the-art imaging techniques have not yet been performed. We aimed to determine RV function and volume in dilated cardiomyopathy and ischaemic heart disease in relation to left ventricular (LV) systo...
