Incidence of chronic heart failure with preserved left ventricular ejection fraction in patients with hypertension and isolated mild diastolic dysfunction.
INTRODUCTION Heart failure (HF) with preserved ejection fraction (HFPEF) is still a challenge in clinical practice. The prognosis of patients with HFPEF is similar to or only slightly better than that of patients with HF with reduced ejection fraction (HFREF). Impaired relaxation is the mildest form of diastolic dysfunction, which should not be accompanied by symptoms of HFPEF. OBJECTIVES The...
متن کاملPrognostic Relevance of Left Atrial Dysfunction in Heart Failure With Preserved Ejection Fraction.
BACKGROUND Left atrial (LA) size is an established marker of risk for adverse outcomes in heart failure with preserved ejection fraction (HFpEF). However, the independent prognostic importance of LA function in HFpEF is not known. METHODS AND RESULTS We assessed LA function measured by speckle-tracking echocardiography in 357 patients with HFpEF enrolled in the Treatment Of Preserved Cardiac ...
متن کاملEffects of exercise on left ventricular systolic and diastolic properties in patients with heart failure and a preserved ejection fraction versus heart failure and a reduced ejection fraction.
BACKGROUND The purpose of the current study was to define exercise-induced changes in indices of left ventricular (LV) systolic and diastolic properties in patients with chronic heart failure (HF), compare these changes in patients with HF and a reduced ejection fraction (EF) versus HF and a preserved EF, and compare the hemodynamic responses to activities of daily living with symptom-limited u...
متن کاملLeft ventricular diastolic and systolic dyssynchrony and dysfunction in heart failure with preserved ejection fraction and a narrow QRS complex
Aims: Mechanical dyssynchrony has been reported in heart failure with preserved ejection fraction (HFpEF), with a majority of patients having a narrow QRS complex; however, whether any benefit is observed with restoration of dyssynchrony remains unclear. We sought to assess left ventricular (LV) dyssynchrony and function in HFpEF and elucidate the underlying mechanisms that may account for HFpE...
