In diastolic heart failure, the left ventricular (LV) ejection fraction (EF) is normal and there is increased passive stiffness with impaired relaxation of the ventricle, resulting in disturbances in the pattern of filling and elevated diastolic pressure.1–3 The mechanism underlying such failure has been thought to be principally diastolic because LV diastolic function is universally abnormal a...
The idea that diastolic dysfunction may give rise to symptoms of cardiac disease independent of any impairment of systolic function is not new, and was appreciated centuries ago.2 Traditional definitions of heart failure have focused on abnormalities of systolic or pump function ofthe heart, emphasizing the failure of cardiac output to meet the metabolic requirements of the body at peak workloa...
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...
Background: Cerebrovascular Accident (CVA) is the second cause of death and disability in the world. Heart failure can co-occur with CVA and increases the risk of death and disability in patients. Objectives: This study aimed to evaluate the prevalence of heart failure in patients with ischemic stroke. Materials & Methods: In this cross-sectional study, the information of patients with ischem...
Objective(s): Exercise training is a well-known accelerator for the treatment of chronic heart failure (CHF). The current study aimed to investigate the restorative effects of aerobic interval training (AIT) intervention on myocardial energy metabolism in CHF rats. Materials and Methods: Post-myocardial infarction (MI) heart failure animal model was established. The Sprague-Dawley rats were ran...

Despite the fact that up to half of all heart failure occurs in patients without evidence of systolic cardiac dysfunction, there are no universally accepted diagnostic markers and no approved therapies for heart failure with preserved ejection fraction (HFpEF). HFpEF, otherwise known as diastolic heart failure, has nearly the same grim prognosis as systolic heart failure, and diastolic heart fa...
