“…Both genders were obese and carried an unfavorable body composition profile, presenting very high BMI (>30 kg/m 2 ), waist-hip ratio (male >0.9, female >0.85), and total body fat (male >28%, female >40%), and low skeletal muscle levels (male <33.1%, female <24.1%). Females presented high visceral fat levels (10)(11)(12)(13)(14), while males presented very high levels (15-30).…”

“…Previous review studies concur that Ramadan fasting has no significant effect on blood pressure measurements of hypertensive subjects [12,13] and claim that fasting may be a safe practice for patients with controlled hypertension [2]. On the other hand, conflicting results were reported for the variation in body weight [6,7,9], as well as in heart rate [9,10], of hypertensive patients during Ramadan fasting.…”

“…Limited number of studies (5 research manuscripts as for April 2020) demonstrated the effect of Ramadan fasting on blood pressure, and cardiovascular parameters in hypertensive patients, who adhered to their antihypertensive medications [6][7][8][9][10]. Previous research was diverse in terms of hypertension grade of subjects that ranged from prehypertensive state [11] to grade 3 hypertension [7].…”

“…In addition, different inclusion criteria were applied (such as diabetes, cardiac hypertrophy, sinus arrhythmia, renal disease, etc. ), and different fasting durations were studied (from 12 hours [7] to 16 hours [10]). Of note, some cardiac outcomes (such as lipid panel [8] and autonomic nervous system [10]) were only evaluated once with a relatively low sample size.…”

“…In a recent study, Mzoughi et al also assessed the autonomic nervous activity during Ramadan and claimed decreased heart rate variability and enhanced sympathetic activity among hypertensive patients with sinus rhythm, who varied significantly in terms of lifestyle characteristics [10].…”

Background. Conflicting results are reported on the effect of Ramadan fasting on the cardiovascular health of patients with hypertension, a highly prevalent cardiovascular disease risk factor. This research aimed to evaluate the impact of fasting on cardiac health and heart rate variability (as a measure of cardiac stress) of hypertensive patients. Methods. Patients with controlled hypertension were followed in a prospective cohort during and after Ramadan. Lipid panel and blood glucose were measured at the end of each phase. Blood pressure and heart rate variability were monitored in the morning, afternoon, and evening of each follow-up day. Results. The study included 58 subjects (mean age: 54 ± 11.5 years, 52% male). Fasting did not affect body composition, lipid panel parameters, and blood pressure of hypertensive subjects; males only presented lower body weight and hip circumference during Ramadan. Blood glucose was significantly higher during Ramadan. Fasting significantly increased HRV during the afternoon period. Conclusions. Ramadan intermittent fasting reduces cardiac stress among hypertensive patients controlled by and adherent to hypertensive medication, without affecting their hypertensive state.

Heart rate variability (HRV) is a measure of the variation between consecutive heartbeats. It provides a marker of the interplay between the parasympathetic and sympathetic nervous systems, and there is an increasing body of evidence confirming an increased HRV is associated with better mental and physical health. HRV may be a useful marker of stress as it represents the ability of the heart to respond to a variety of physiological and environmental stimuli. HRV tends to decrease as we age and is positively associated with physical activity, fitness, and healthier lifestyles. The relation between HRV and micronutrients (vitamins and minerals) has also received some attention in the research literature. In this review, cross-sectional and interventional studies on human populations examining the relation between HRV and micronutrients are appraised. Micronutrients identified and examined in this review include vitamins D, B-12, C, and E; the minerals magnesium, iron, zinc, and coenzyme Q10; and a multivitamin-mineral formula. Due to the paucity of research and significant heterogeneity in studies, definitive conclusions about the effects of these micronutrients on HRV cannot be made at this time. However, there is accumulating evidence suggesting deficiencies in vitamins D and B-12 are associated with reduced HRV, and zinc supplementation during pregnancy can have positive effects on HRV in offspring up until the age of 5 y. To further elucidate the relation between micronutrients and HRV, additional robustly designed and adequately powered studies are required.

Impact of Fasting on Cardiovascular Outcomes in Patients With Hypertension

Fasting has been frequently practiced for religious or medical purposes worldwide. However, limited literature assesses the impact of different fasting patterns on the physiologic and cardiac-related parameters in patients with hypertension. This review aims to examine the effect of fasting on cardiovascular outcomes in hypertensive patients. Medline, Embase, and Cochrane library were systematically screened until March 2021 for observational prospective cohorts investigating the effect of fasting on cardiovascular outcomes. Articles were assessed by searching for hypertension and fasting, both as Medical Subject Headings (MeSH) terms and text words. The review included studies assessing Ramadan, intermittent, and water-only fasting. Water-only fasting reduces body weight, blood pressure, and lipolytic activity of fasting hypertensive patients without affecting average heart rate. Ramadan fasting enhances lipid profile, although it shows conflicting results for body weight, blood pressure, and heart rate variability. Considering the limited studies in this field, further research should be conducted to support the clinical impact of fasting on the cardiovascular health of patients with hypertension.
