Background and Objective: Various biomarkers lead to the incidence of pathologic left ventricular hypertrophy such as Cardiotrophin-1. The aim of the present study was to investigate the impact of 12 weeks of aerobic exercise on serum levels of cardiotrophin-1, blood pressure and left ventricular hypertrophy in hypertensive elderly women. Materials and Methods: In this study, 40 women age...
Background: The aim of this study was to evaluate the effect of eight weeks of endurance training and Empagliflozin consumption on inflammatory markers and their relationship with heart structure and function of diabetic male Rats. Methods: 40 male Wistar rats were randomly divided into five groups: healthy control, diabetic control, diabetic + empagliflozin, diabetic + endurance training and ...
Objective: To compare clinical and haemodynamic variables between left ventricular and biventricular pacing in patients with severe heart failure; and to analyse haemodynamic changes during daily life and maximum exercise during chronic left ventricular and biventricular pacing. Design: Prospective single blinded randomised study with crossover. Setting: University hospital (tertiary referral c...
Background Surgical ventricular restoration (SVR) after anterior myocardial infarction with post infarction aneurysm, significantly improves left ventricular (LV) performance. To describe mid-term postoperative changes of shape and performance of the newly created LV and mitral valve function through the classical (SI) and apical (ASI) left ventricular sphericity index, and determinants of mitr...
Left ventricular performance during percutaneous transluminal coronary angioplasty was assessed in 52 patients by intravenous digital subtraction ventriculography. After injection of contrast into the right atrium ventriculograms were obtained before and during balloon inflation. In 37 patients they were also obtained after the procedure. A 12 lead electrocardiogram was monitored throughout. Du...
As the mitral valvular apparatus tenses during systole, forces transmitted along the chordae tendineae to the left ventricular chamber may influence left ventricular performance. To test this hypothesis, 10 dogs anesthetized with fentanyl were studied during cardiopulmonary bypass. The importance of the mitral apparatus in left ventricular systolic function was assessed independent of load by m...
A woman with advanced coronary artery disease underwent heart transplantation. The donor heart had left ventricular hypertrophy. The electrocardiographic and echocardiographic evidence, of left ventricular hypertrophy regressed during follow up; estimated left ventricular mass decreased from 393 g to 171 g. The adaptation of myocardial mass and performance after transplantation is not fully und...
The effect of beta-adrenergic blockade with oral propranolol on resting, exercise and postexercise ventricular performance was evaluated using multiple-gated equilibrium cardiac blood and pool images in normal volunteers and patients with coronary artery disease. Propranolol produced no detectable effect on basal left ventricular function in normal subjects at doses producing intermediate (160 ...
