Exercise capacity in patients with LV dysfunction.
In the dysrhythmias shown in our figure 1, two appeared before ST-segment elevation reached its acme and therefore were classified as representing an occlusive type of dysrhythmia. Some of the electrical abnormalities produced during the occlusive phase (i.e., progressive delay of subepicardial activation),7 are maintained during early phase immediately after coronary reperfusion. These may be ...
متن کاملExercise capacity in patients with severe left ventricular dysfunction.
Normal or near-normal exercise capacity has been thought to reflect normal left ventricular function. Many compensatory mechanisms could preserve exercise capacity in patients with severe left ventricular dysfunction. We evaluated exercise capacity using a treadmill exercise test in 26 patients with severe left ventricular dysfunction defined by a left ventricular ejection fraction of 30% or le...
متن کاملRegular physical exercise corrects endothelial dysfunction and improves exercise capacity in patients with chronic heart failure.
BACKGROUND The purpose of this study was to determine the effects of systemic exercise training on endothelium-mediated arteriolar vasodilation of the lower limb and its relation to exercise capacity in chronic heart failure (CHF). Endothelial dysfunction is a key feature of CHF, contributing to increased peripheral vasoconstriction and impaired exercise capacity. Local handgrip exercise has pr...
متن کاملSubclinical LV Dysfunction Detection Using Speckle Tracking Echocardiography in Hypertensive Patients with Preserved LV Ejection Fraction
BACKGROUND Early detection of subclinical left ventricular (LV) systolic dysfunction in hypertensive patients is important for the prevention of progression of hypertensive heart disease. METHODS We studied 60 hypertensive patients (age ranged from 21 to 49 years, the duration of hypertension ranged from 1 to 18 years) and 30 healthy controls, all had preserved left ventricular ejection fract...
متن کاملContribution of exercise-induced mitral regurgitation to exercise stroke volume and exercise capacity in patients with left ventricular systolic dysfunction.
BACKGROUND Functional mitral regurgitation (MR) is common in patients with heart failure and left ventricular (LV) dysfunction, and its severity may vary over time, depending primarily on the loading conditions. Because dynamic changes in the severity of functional MR may affect forward stroke volume, we hypothesized that exercise-induced changes in MR severity influence the stroke volume respo...
