HLA-DQ2 and HLA-DQ8 Haplotypes in Heart Failure Patients with Reduced Ejection Fraction

Objectives: Genetic predisposition is one of the factors that contribute to the etiology of heart failure (HF). This study aimed to compare the prevalence of human leukocyte antigen (HLA)-DQ2 and HLA-DQ8 haplotypes in patients with HF with reduced ejection fraction (HFrEF) and healthy controls. Methods: This case contr …

A Pattern Recognition Technique Based on Wavelet Decomposition for Identification of Patients With Congestive Heart Failure

… lted from wavelet decomposition of R-R interval (RRI) data for identification of patients with Congestive Heart Failure (CHF) is investigated. Both trial and test data used in this work are drawn from MIT databases. Two standard patterns of the base-2 logarithmic values of the reciprocal of the probability measure of t …

Heart Rate Variability Time Analyses of the Streptozotocin- Diabetic Rat

… lycaemia. This study confirms that this animal model also displays DM physiological effects in the animal heart rate (HR) and heart rate variability (HRV). In particular, 5 minutes of rat (n=13) electrocardiogram (ECG) is acquired hourly for 30 days. At day 10, the animal (n=7) is dosed with STZ and the ECG is analyzed …

Statistical Signal Characterization of Spectral Analysis of Heart Rate Variability for Screening of Patients with Obstructive Sleep Apnea

A new screening technique for obstructive sleep apnea (OSA) is implemented. This technique is based on finding the statistical signal characterization (SSC) parameters of the spectrum of pre-processed R-R-interval (RRI) data. A single classification factor (CR) is selected to classify between patients with obstructive …

Effects of head posture on intraocular pressure and heart rate of human beings

… ead posture on intraocular pressure (IOP). The study aimed to evaluate and measure the changes in IOP and heart rate (HR) of human beings on head-down posture. The study included 105 patients at the department of ophthalmology of a tertiary care center in India. Subjects and methods: Patients underwent applanation tono …

Some Risk Factors for Coronary Heart Disease among Omani Males A matched case-control study

Objectives: Evaluation of some of the leading risk factors for coronary heart disease (CHD) among males in Oman. Methods: We conducted a hospital-based pair-wise matched case-control study among Omani CHD patients admitted in the Sultan Qaboos University Hospital and the Royal Hospital located in Muscat, Oman. The case …

Screening of Patients with Snoring and Obstructive Sleep Apnoea using Heart Rate Variability Indices

… on disorders. Snoring associated with excessive daytime sleepiness is the most prevalent symptoms of OSA. Heart rate variability (HRV) is altered in patients with OSA and the degree of alteration may be linked to the severity of OSA. Alterations in HRV in 24 hour tachograms have recently been used in screening OSA pati …
