Diastolic heart failure, diastolic left ventricular dysfunction and exercise intolerance.
The phenomenon of “diastolic heart failure” is rightly receiving greater attention (1–4); community-based studies such as those in Framingham (5) and Olmsted County (6) show that up to 50% of older persons with heart failure do not have impaired left ventricular (LV) systolic function to account for this, and that the condition is usually associated with LV hypertrophy and is preceded by elevat...
متن کاملDiastolic Mechanisms for Systolic Dysfunction During Exercise
many patients with essential hypertension. To assess the determinants of the abnormal ejection fraction response to exercise, we performed radionuclide angiography at rest and during exercise in 41 hypertensive patients without coronary artery disease. In 22 patients (group 1), the ejection fraction increased more than 5% during exercise; in the other 19 patients (group 2), the ejection fractio...
متن کاملExercise training attenuates age-associated diastolic dysfunction in rats.
BACKGROUND In contrast to systolic function, which is relatively well preserved with advancing age, diastolic function declines steadily after age 30. Our goal was to determine whether changes in diastolic function that occur with aging could be reversed with exercise training. Methods and Results-- Adult (6-month-old) and old (24-month-old) Fischer 344/BNF1 rats were studied after either 12 we...
متن کامل[Dysfunction of diastolic [Ca²⁺] in cardiomyocytes isolated from chagasic patients].
INTRODUCTION AND OBJECTIVES Chagas is an endemic disease in Latin America, caused by the parasite Trypanosoma cruzi, which usually affects the functioning of the heart. We have studied the regulation of intracellular calcium in cardiomyocytes isolated from chagasic patients with different degrees of heart dysfunction. METHODS Calcium selective microelectrodes were used to simultaneously measu...
