Assessment of left ventricular diastolic function and recognition of diastolic heart failure.
Left ventricular (LV) diastolic dysfunction, as occurs in patients with hypertension, diabetes mellitus, and/or aging, carries a substantial risk of the subsequent development of heart failure and reduced survival, even when it is asymptomatic or “preclinical.”1–4 Diastolic dysfunction is defined as functional abnormalities that exist during LV relaxation and filling. When such abnormalities ca...
متن کاملDiastolic 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 کاملEchocardiographic Assessment of Left Ventricular Diastolic Function
J Echocardiogr Vol.6, No.3, 2008 57 The concepts for the assessment of left ventricular (LV) diastolic function were established in the cardiac catheterization laboratory and necessitate the use of high fidelity pressure and conductance catheters. The most recent [1] set of criteria (Figure 1) for diagnosing diastolic heart failure (DHF) include the presence of increased LV filling pressures (m...
متن کاملLeft atrial function in diastolic heart failure.
BACKGROUND Abnormalities in left ventricular (LV) structure and function occur in patients with diastolic heart failure (DHF). The reasons for the transition from asymptomatic dysfunction to heart failure need better definition, including noninvasive measurements that can detect the transition. METHODS AND RESULTS In 64 patients undergoing right heart catheterization, simultaneous echocardiog...
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 ...
