Levels of BP have been associated with increasing rates of renal allograft failure from cadaveric donors, independent of renal function. The effect of BP, a modifiable risk factor, on the failure rates of renal allografts from living donors is unknown and maybe obscured by the rate of decline of renal function from this source of organs. A nonconcurrent cohort study collecting data from 392 rec...
BACKGROUND Cardiac resynchronization therapy results in improved ejection fraction in patients with heart failure. We sought to determine whether these effects were mediated by changes in contractility, afterload, or volumes. METHODS AND RESULTS In 610 patients with New York Heart Association class I/II heart failure from the Resynchronization Reverses Remodeling in Systolic Left Ventricular ...
The aim of this study was to determine the relationship between falls and beat-to-beat blood pressure (BP) variability.Continuous noninvasive BP measurement is as accurate as invasive techniques. We evaluated beat-to-beat supine and standing BP variability (BPV) using time and frequency domain analysis from noninvasive continuous BP recordings.A total of 1218 older adults were selected. Continu...
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...
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...
AIM Chronic heart failure is associated with endothelial dysfunction and insulin resistance. The aim of this investigation was to study insulin-stimulated endothelial function and glucose uptake in skeletal muscles in patients with heart failure in comparison to patients with type 2 diabetes. METHODS Twenty-three patients with systolic heart failure and no history of diabetes, seven patients ...
background: hypertension is a risk factor for many diseases. nutritional methods are considered as major tools in lifestyle modification for lowering blood pressure. the present study was conducted to determine the level of dietary adherence in hypertensive patients. methods: this descriptive-analytical study was performed in 2015, on hypertensive patients who were referred to heart clinic of s...
Background and purpose: Heart failure (HF) is characterized by decreased ability of the heart to provide sufficient blood flow or fill with the blood. Hyponatremia is the most commonly seen electrolyte abnormality in patients with heart failure that is associated with increased morbidity and mortality. The aim of this study was to assess the correlation between hyponatremia and high risk clinic...
