Detailed Description:
Introduction
Assessment of the heart rate HR is an essential process to determine proper exercise training intensity 1 Utilization of the 12-leads electrocardiogram ECG is considered most objective heart rate assessment procedure Polar chest strap arises as an alternative to the ECG when it is not accessible to use it outside the laboratories The Polar chest strap proved valid and reliable instrument when tested against the ECG in healthy subjects 2-4 and patients with cardiac diseases 5 at rest and during training Monitoring the resting as well as the post-training heart rate heart rate recovery is essential because it helps predicting the cardiopulmonary fitness level as well as the mortality risk among evaluated personnel 6
Diabetes mellitus is a rapidly growing non-communicable chronic disease worldwide becoming one of the most alarming health problems in the 21st century The overall estimated prevalence of diagnosed diabetes in 2018 was 269 million US subject of all ages 82 of the US population 7 The International Diabetes Federation IDF has estimated the total number of persons with DM across the world will rise from 5366 million in 2021 to 7832 million by 2045 with about 94 of the increase in the number of subjects with diabetes by 2045 will be within the low and middle-income countries The global incidence also projected to increase from 163 in 2021 to 192 by 2025 in middle- and low-income countries The prevalence of diabetes in adults 20-79 years old in the Middle East and North Africa was estimated to be 162 compared to 193 in 2045 8 Hypertension possess significantly increased public health risk and population challenge The prevalence of hypertension was 60 42 and 49 in male female and all subjects respectively 9 Hypertension prevalence is increasing in KSA the rate exceeds 25 among the adult Saudi subjects Monitoring the hypertension-related disturbances is an urgent concept to prevent its organs-damaging 10 Regional study at Majmaah Saudi Arabia reported that the hypercholesterolemia prevalence was 453 with no significant difference between both genders 11 A study by Al-Nozha et al reported that the hyperlipidemia continues reaching higher prevalence rate recently The hypercholesterolemia prevalence among the 30-70 years old subjects reached 549 and 532 for males and females respectively Hypertriglycemia prevalence was 476 in male compared to 337 in females 12 More recently a study by reported that the prevalence of Hypercholesterolemia among Saudi population years old is around 125 with males have higher rate 567 compared to females who have lower s rate 433 Close monitoring of the vital signs and cardiovascular variables in patients with chronic non-communicable diseases is indicated since many harmful consequences can be prevented via increasing community awareness and education 13 Diabetes Mellitus is chronic debilitating disorder requires well-organized efforts and continuous monitoring to limit the impact of disease-associated hazards and long-term complications 14 The process of SpO2 evaluation is important because it indirectly reflects the subjects organs oxygen requirements The traditional SpO2 measuring procedure is invasive and painful requiring collection and assay of arterial blood sample using a blood gas analyzer 15 Previous trials proposed evaluating the SpO2 non-invasively using simple procedure with keeping maximum accuracy 16 Pulse oximetry is a well-known noninvasive instrument used for monitoring and evaluation of SpO2 17 Routine and frequent screening of patients with chronic diseases is recommended especially with age over 50 years and presence of other comorbidities as HTN and hyperlipidemia 18 Pulse oximetry is used to measure the level of the SpO2 with low blood flow is associated with lower SpO2 19 The HR is tightly and linearly correlated with the oxygen consumption at specified time point20 Monitoring of other vital variables as the oxygen saturation SpO2 is recommended in patients suffering hypoxia to improve their survival 21 as in post-operative and post-arrest cardiac patients 22 with the pulse oximeter is the widely used instrument to evaluate the SpO2 because of accuracy and ease of application 23 Quiet recently the Apple smart watch appeared as a new tool to measure the HR all the Apple watch versions can monitor the HR but the blood SpO2 can be only measured by only the latest 6 and 7 versions The concept of utilizing the Apple watch to measure the HR depends on the Photoplethysmography PPT non-invasive measurement procedure applied using wrist-worn watch that continuously monitors both heart beats and blood color changes over time The PPT is a commonly used approach to measure the cardiac output blood pressure and SpO2 in verities of medical instruments 24 that can help discovering the cardiovascular insults and complications at early stages 25 Implemented new technology and updated features that enable the Apple watch to monitor the HR is available only in updated series-6 and 7 Very limited number of studies evaluated the validity of the Apple watch against pulse oximeter in measuring the SpO2 the Spo2 was evaluated in 23 patients with chronic obstructive pulmonary disease 61 patients with interstitial lung diseases and 16 health control subjects the Apple watch results showed strong positive correlations with that of the pulse oximeter r081 P00001 furthermore this study recommended testing the Apple watch validity for measuring the SpO2 in other groups of patients 26 The Apple watch is a smart instrument with advanced technology measuring the Spo2 and heart rate but its validity in patients with chronic diseases including patients with diabetic mellites hypertension and hyperlipidemia is still unknown Therefore this will be the first study to evaluate the Apple watch accuracy and validity in measuring the Spo2 and heart rate in patients with chronic diseases including diabetic mellitus hypertension hyperlipidemia
Method
A cross sectional study will be conducted ninety-five chronic patients will be invited to participate in this study The study design will be in form of 3-groups first group will include 35 patients with diabetes and the second group will include 35 patients with hypertension The third group will be around 35 patients with hyperlipidemia The distribution of patients and number of groups will be based on the availability of the patients with chronic non-communicable diseases at Umm Al-Qura University Medical Center All participants in this study will wear the Polar chest strap HR and the Apple Watch at rest during short session of mild to moderate intensity exercise 50-70 maximum heart rate-Resting heart rate resting heart rate for 15 minutes and after exercise The pulse oximeter will be used at rest pre and after exercise
Under resting condition the pulse oximeter will be fitted on a warm finger while the participant assumes setting position with the patient in the upright sitting position and resting The SpO2 reading will be recorded after being stabilized on the pulse oximeter instrument 27 28 The exercise session will be about 15-minutes duration at mild to moderate intensity according to the heart rate reserve HRR using the treadmill and the cycle ergometer preceded by a 3-minutes warm-up and followed by 3-minutes cool-down The HR will be recorded every 30 seconds during whole period and the oxygen saturation will be recorded five times at rest and after exercises
