"Diastolic heart failure" or heart failure caused by subtle left ventricular systolic dysfunction?
OBJECTIVES To determine whether patients with suspected heart failure but preserved systolic function, as determined by conventional echocardiographic measures (often said to have "diastolic heart failure), might have subtle left ventricular systolic dysfunction detectable by a new measure of left ventricular systolic function-left ventricular systolic atrioventricular plane displacement. DES...
متن کاملmiR-21 is associated with fibrosis and right ventricular failure.
Combined pulmonary insufficiency (PI) and stenosis (PS) is a common long-term sequela after repair of many forms of congenital heart disease, causing progressive right ventricular (RV) dilation and failure. Little is known of the mechanisms underlying this combination of preload and afterload stressors. We developed a murine model of PI and PS (PI+PS) to identify clinically relevant pathways an...
متن کاملIs there any difference between Vitamin D deficiency among heart failure and Non-heart failure elderly with cardiovascular disease?
Vitamin D deficiency is common among the elderly with and without heart failure (HF). This study was designed to identify the degree of vitamin D deficiency among HF and Non- HF elderly with cardiovascular disease. In this study, fifty hospitalized elderly patients with HF (26 women and 24 men, age range 60-90 years) and fifty elderly without HF were randomly selected. The level of serum 25-hyd...
متن کاملLeft and right ventricular diastolic dysfunction and diastolic heart failure: does one lead to the other?
Background and Objective Diastolic dysfunction of the left ventricle is a mechanical abnormality diagnosed primarily by echocardiogram, and can be distinguished into three separate degrees based on the severity of reduction in passive compliance and active myocardial relaxation. Methods A literature search was performed for basic science studies, clinical studies and major practice guidelines o...
متن کاملThe clinical quandary of left and right ventricular diastolic dysfunction and diastolic heart failure
Diastolic heart failure is a common clinical entity that is indistinguishable from systolic heart failure without direct evaluation of left ventricular function. Diastolic heart failure is a clinical diagnosis in patients with signs and symptoms of heart failure but with preserved left ventricular function and normal ejection fraction, and is often seen in patients with a long-standing history ...
