OBJECTIVES To compare the clinical characteristics and short- and long-term prognosis for chronic heart failure with left ventricular systolic dysfunction or preserved systolic function. PATIENTS AND METHOD Three-hundred twenty-eight consecutive patients with decompensated chronic heart failure were studied prospectively. Depending on ejection fraction, participants were classified as having ...

BACKGROUND Regarding the relationship between blood pressure (BP) and shift work (SW), previous studies have reported contradictory results. In the present study, we used Bayesian multilevel modeling to evaluate the association of SW and BP after controlling some confounding factors. METHODS Data of this multicenter historical study were extracted from annual observations of the male workers ...
High blood pressure (BP), a major established predictor of cardiovascular disease, is the leading risk factor for mortality worldwide.1,2 Both systolic BP (SBP) and diastolic BP (DBP) have continuous, independent relations with the risk of cardiovascular disease3; however, considerable uncertainty persists about the relative importance of SBP, DBP, and their combination in predicting cardiovasc...
Congestive heart failure with preserved left ventricular systolic function has emerged as a growing epidemic medical syndrome in developed countries, which is characterized by high morbidity and mortality rates. Rapid and accurate diagnosis of this condition is essential for optimizing the therapeutic management. The diagnosis of congestive heart failure is challenging in patients presenting wi...
Aging is often associated with increased systolic blood pressure and decreased diastolic blood pressure. Isolated systolic hypertension or an elevated systolic blood pressure without an elevated diastolic blood pressure is a known risk factor for incident heart failure in older adults. In the current study, we examined whether isolated diastolic hypotension, defined as a diastolic blood pressur...
Diastolic heart failure (heart failure with preserved systolic function) causes 30% to 50% of all cases of heart failure, and its prognosis is almost as ominous as that of systolic heart failure. Currently, it is diagnosed when clinical criteria for heart failure are present and left ventricular ejection fraction is preserved (higher than 40% to 50%). However, determinations of brain natriureti...
Disturbances in cardiovascular neural regulation, influencing both disease course and survival, progress as heart failure worsens. Heart failure due to left ventricular systolic dysfunction has long been considered a state of generalized sympathetic activation, itself a reflex response to alterations in cardiac and peripheral hemodynamics that is initially appropriate, but ultimately pathologic...
