Heart failure is a common clinical syndrome characterized by dyspnea, fatigue, and signs of volume overload, which may include peripheral edema and pulmonary rales. Heart failure has high morbidity and mortality rates, especially in older persons. Many conditions, such as coronary artery disease, hypertension, valvular heart disease, and diabetes mellitus, can cause or lead to decompensation of...

BACKGROUND The prevalence and clinical outcomes of heart failure with preserved left ventricular ejection fraction after acute myocardial infarction have not been well elucidated. OBJECTIVE To analyze the prevalence of heart failure with preserved left ventricular ejection fraction in acute myocardial infarction and its association with mortality. METHODS Patients with acute myocardial infa...

OBJECTIVES To assess the prevalence, clinical profile and medium-term prognosis in patients with heart failure and preserved systolic ventricular function compared to those with systolic dysfunction. PATIENTS AND METHOD 153 patients were included, 62 with preserved systolic ventricular function (left ventricular ejection fraction > or = 45%) and 91 with impaired systolic ventricular function ...

the present study aimed to compare the serum level of uric acid in patients with and without heart failure and also to determine the association between uric acid level and clinical status by killip class in patients with stemi. this case-control study was conducted on 50 consecutives as control group and 50 patients with acute heart failure, (20 patients had acute stemi), who documented by bot...

Heart failure is frequently a result of impaired systolic ventricular performance. We describe a patient with heart failure and a systemic arteriovenous fistula who had left ventricular enlargement and a normal left ventricular ejection fraction, demonstrated by gated cardiac blood pool scanning. The heart failure was relieved by surgical repair of the fistula, but the left ventricular ejection...

Nearly half of patients with symptoms of heart failure are found to have a normal left ventricular (LV) ejection fraction. This has variously been labelled as diastolic heart failure, heart failure with preserved LV function or heart failure with a normal ejection fraction (HFNEF). As recent studies have shown that systolic function is not entirely normal in these patients, HFNEF is the preferr...
