Electrocardiographic and Hemodynamic Changes
To investigate the electrocardiographic and hemodynamic changes in isolated right ventricular infarction, 0.25 ml or 0.5 ml of metallic mercury was injected into the right coronary artery of 14 closedchest dogs. At autopsy, at least 60% of the right ventricle was necrotic in every dog. Heniodynamic observations were made in 11 and electrocardiographic mapping was performed in all 14 dogs. Right...
متن کاملAdverse Effects of Common Drugs: Dietary Supplements.
Dietary supplement-induced adverse effects often resolve quickly after discontinuation of the offending product, especially in younger patients. The potential for unwanted outcomes can be amplified in elderly patients or those taking multiple prescription drugs, especially where interactions exist with drugs metabolized by cytochrome P450 enzymes. Attributing injury or illness to a specific sup...
متن کاملElectrocardiographic and hemodynamic effects of a multicomponent dietary supplement containing ephedra and caffeine: a randomized controlled trial.
CONTEXT Metabolife 356, a multicomponent dietary supplement containing ephedra and caffeine (DSEC) in addition to several other components, is the top-selling dietary weight loss supplement. Given its common use, anecdotal reports of cardiovascular and cerebrovascular adverse events, and paucity of safety data, further research with this DSEC was warranted. OBJECTIVE To determine the impact o...
متن کاملHemodynamic Effects of Dietary Sodium in Man
The effect of dietary sodium manipulation was studied In 27 normal subjects and 19 patients with borderline hypertension. Sodium-loading caused an Increase in blood pressure (BP) in 14 of 19 borderline hypertensive patients but in only 4 of 27 normal subjects (X* = 13.85, p < 0.01). In the normal subjects, a 10 mEq sodium diet resulted in a fall in supine mean blood pressure (MBP) of 43% after ...
متن کاملHemodynamic and Hematologic Profile of Healthy Adults Ingesting Dietary Supplements Containing 1,3-Dimethylamylamine and Caffeine
BACKGROUND 1,3-dimethylamylamine (a constituent of geranium), alone and in combination with caffeine, is widely used within dietary supplements. We have recently determined the hemodynamic effects of 1,3-dimethylamylamine and caffeine alone and in combination, using a single ingestion study. However, no study has determined the hemodynamic effects of these ingredients following chronic use. Mor...
