Objective: To study the clinical efficacy of meglumine adenosine cyclophosphate combined with perindopril in treating patients with chronic heart failure. Methods: Three hundred and twelve patients with chronic heart failure were enrolled and divided evenly into an observation group and a control group according to treatment methods, one hundred and fifty-six patients in each group. Patients in...
Thirty-one left ventricular (LV) biplane angiograms were performed in 28 patients with tricuspid atresia. Measurements of left ventricular end-diastolic volume (LVEDV) and left ventricular end-systolic volume were obtained by the modified Simpson's rule and systolic ejection fraction (EF) calculated. Left ventricular volumes and ejection fractions were also obtained in 19 control patients with ...
Felodipine is a new calcium antagonist with a high degree of vascular selectivity. To examine its potential value as an afterload reducing agent in congestive heart failure 11 patients were studied. Substantial increments in cardiac index were associated with a fall in systemic vascular resistance. Left ventricular end diastolic pressure was also significantly reduced. Although left ventricular...
Left ventricular end-systolic pressure-wall thickness and pressure-segment length relations have been used to assess regional myocardial contractility. The purpose of these studies was to determine whether the method of afterload alteration, coronary perfusion pressure, and the definition of end systole affected regional end-systolic relations. In paced open-chest pig hearts (n = 10), left vent...
To determine whether a ventricular (LV) end-systolic dimension (ESD) > 55 mm and LV left fractional shortening < 25% are risk factors for aortic valve replacement (AVR) in patients with aortic insufficiency, we analyzed the clinical course and M-mode echocardiograms in 47 consecutive patients who underwent AVR for isolated symptomatic Al. Group 1 patients (n = 27) had a preoperative ESD < 55 mm...
Glossopharyngeal insufflation (GI), a technique used by breath-hold divers to increase lung volume and augment diving depth and duration, is associated with untoward hemodynamic consequences. To study the cardiac effects of GI, we performed transthoracic echocardiography, using the subcostal window, in five elite breath-hold divers at rest and during GI. During GI, heart rate increased in all d...
BACKGROUND The diabetic heart exhibits increased left ventricular (LV) mass and reduced ventricular function. However, this relationship has not been studied in patients with aortic stenosis (AS), a disease process that causes LV hypertrophy and dysfunction through a distinct mechanism of pressure overload. The aim of this study was to determine how diabetes mellitus (DM) affects LV remodeling ...
Objective: Acute coronary syndromes (ACS) represent the acute life threatening phase of coronary artery disease [1] , registries and surveys have the potential to define the 'gaps' between evidence and practice as well as implementation of guidelines [2] . Aim of the Work: To assess the application of a newly designed registry among Egyptian patients with ACS and to compare the results with tho...
The relation between the left atrial systolic pressure waveform and left ventricular end-diastolic pressure was observed in 17 patients who underwent diagnostic cardiac catheterization. Left atrial pressure and left ventricular pressure were simultaneously recorded from a multisensor catheter before and during angiotensin infusion. Left ventricular systolic pressure and left ventricular end-dia...
The value for the slope of the left ventricular (LV) end-systolic pressure-dimension and pressure-volume relations has been proposed as a quantitative measure of the LV inotropic state. This measure of LV inotropic state is attractive because it is independent of preload and incorporates afterload. To investigate the sensitivity of the slope of these relations to alterations in contractile stat...
