Effects of exercise and stress management training on nighttime blood pressure dipping in patients with coronary heart disease: A randomized, controlled trial

Health football beats them all: subgroup analysis of the 3F (Fit&Fun with Football) study on white-coat hypertension, sustained hypertension, dippers, nondippers, and on pharmacologically un(treated) arterial hypertension

BACKGROUND

The 3F study (Fit&Fun with Football) demonstrated a significant reduction in blood pressure, antihypertensive medication, body weight, stress and depression through health football. Health football could be a popular tool to unleash the full preventive potential of physical activity. This work analyses the effect of health football on hypertensive subgroups: dipper, nondipper, white-coat hypertension (WCH), sustained hypertension, (un)treated hypertensive patients (UH, TH).

METHODS

A prospective interventional study with 1-year follow-up. Football group (FG): n  = 103, 'health'-football training (1×/week, 90 min) led by licensed football coaches. Physical inactive, hypertensive patients older than 45 years were compared with a control group (CG) ( n  = 105). Subgroups were divided by ambulatory blood pressure monitoring (ABPM), casual blood pressure (CBP), medication schedule and compared by blood pressure (BP), laboratory results and weight.

RESULTS

In all three subgroups (WCH vs. sustained hypertension, TH vs. UH, D vs. ND), health football reduced BP and weight significantly compared with the CG, and compared with the admission. An even greater effect in CBP was found in people with WCH than in sustained hypertension (FG: WCH: 141-127 mmHg, sustained Hypertension (SH): 142-132 mmHg; CG: WCH: 141-143 mmHg, SH: 140-141 mmHg). In contrast, the significant reduction in CBP and ABPM was comparable in treated and untreated patients, although antihypertensive drugs were reduced significantly more frequently in FG than in CG. BP reduction in nondippers and dippers was also comparable. In the nondipper group, nocturnal BP was significantly reduced in the FB (122.0-111.5 mmHg), but not in the CG or the dippers.

CONCLUSION

All evaluated football subgroups achieved a significant BP reduction (compared with CG). This applied to dipper, nondipper, (un)treated hypertension, WCH and SH. All mentioned subgroups displayed a clear benefit. The even greater reduction in BP in WCH demonstrates the importance of physical activity before the additional prescription of antihypertensive medications, underscoring the recommendations of the ESC and ISH in WCH.

Evaluating the Feasibility and Efficacy of A Novel CBTi/SMT Treatment Protocol for Cardiac Rehab Patients: A Non-Randomized Pilot Trial

INTRODUCTION

Cardiac patients and those with chronic medical conditions often suffer from comorbidities such as insomnia and mood disorders. Previous treatment protocols have focused on resolving symptoms of anxiety and depression in this population using Stress Management Training (SMT). However, these treatments have neglected the importance of sleep problems in these patients. This pilot trial sought to address this by examining the feasibility of a novel CBTi/SMT treatment protocol.

METHODS

42 participants attending a Cardiac Rehab (CR) exercise program registered in this 7-week non-randomized pilot trial. The primary objective of the pilot trial was to determine the feasibility of the protocol for retention and adherence rates. Secondarily, the authors sought to examine the potential efficacy of the program in terms of treating insomnia, depression, anxiety, emotion dysregulation, and arousal.

RESULTS

29 participants attended at least 1 class, with 21 participants completing the program. The average attendance for the program completers was 6 out of 7 classes (SD = 0.8) with four days of practice each week (SD = 1.6) for 33 minutes daily (SD = 16.8). Moreover, the number of participants meeting clinical threshold for insomnia, anxiety, and/or depression was significantly reduced at post-treatment and follow-up. Similarly, raw scores on the relevant scales were significantly reduced at both timepoints.

CONCLUSION

This pilot trial provided preliminary evidence for the feasibility and efficacy of targeting sleep improvement with a combined CBTi/SMT protocol. This provides the groundwork for future RCTs to establish the effectiveness of targeting insomnia in a range of medical populations.

Aerobic exercise training improves nocturnal blood pressure dipping in medicated hypertensive individuals

OBJECTIVE

The absence of nocturnal blood pressure (BP) reduction at night in hypertensive individuals is associated with an increased cardiovascular risk. The main purpose of the present study was to investigate the effects of an aerobic training intervention on nocturnal BP dipping in medicated hypertensive individuals.

METHODS

At baseline, hypertensive individuals under pharmacological treatment underwent 24-h ambulatory BP monitoring and a morning urine sample to analyze albumin creatinine ratio (UACR). Then, participants were divided into nocturnal dippers ( N = 15; 59 ± 6 years) and nondippers ( N = 20; 58 ± 5 years) according to a day-to-night BP reduction of >10% or <10%, respectively. Next, participants underwent a 3-weekly, 4-month aerobic interval training intervention.

RESULTS

Follow-up measurements revealed a reduction in daytime diastolic BP in dippers and nondippers ( Ptime < 0.001), whereas nighttime systolic BP was reduced only in nondippers ( P = 0.004). Regarding dipping pattern, nocturnal systolic BP dipping increased after training in nondippers (5 ± 3 to 9 ± 7%; P = 0.018), whereas in dippers, there was a decrease in nocturnal dipping after training (14 ± 4 to 10 ± 7%, P = 0.016). Nocturnal diastolic BP dipping did not change in nondippers (8 ± 5 to 10 ± 7%; P = 0.273) but decreased in dippers (17 ± 6 to 12 ± 8%; P = 0.004). In addition, UACR was significantly reduced in both groups after training ( Ptime = 0.020).

CONCLUSION

Aerobic exercise training is associated with nocturnal BP dipping as nighttime BP was lower than before the program in medicated hypertensive individuals with an initial nondipping phenotype. The lack of improvement in individuals with a dipping phenotype warrants further investigation to discern whether dipping phenotypes influence BP responses to exercise training.

Exercise Intervention to Normalize Blood Pressure and Nocturnal Dipping in HyperTensive Patients (END-HT): Protocol of a Randomized Controlled Trial

BACKGROUND

Lack of decrease (≤10%) in systolic blood pressure (BP) during sleep, referred to as non-dipping (ND), independently predicts cardiovascular events and mortality. There has been no prospective and adequately powered randomized controlled trial (RCT) to determine whether exercise, when compared with standard treatment, can normalize ND in patients with hypertension (HT). Further, most patients do not sustain an exercise program by 12 months.

METHODS

A 2-arm, assessor-blinded RCT, involving 198 hypertensive Chinese patients who have ND will be conducted to evaluate the effectiveness of a combined exercise (aerobic exercise and resistance training) program to normalize ND. The combined exercise program, "exercise is medicine" (EIM), was developed to maintain exercise habit using a variety of techniques (e.g. 12-week exercise classes, mobile application, wrist trackers, self-scheduling, monitoring, regular feedback, and motivational interviewing). Eligible patients will be randomized to EIM plus usual care or to usual care in 1:1 ratio by stratified randomization according to age and sex. The randomization sequence is blinded to the investigators and allocation is disclosed only after valid consent. Ambulatory BP measurements will be performed at baseline, 3, and 12 months. The primary outcome is proportion of participants with ND at 3 months; secondary outcomes include proportion of participants with ND at 12 months, absolute BP values at 3 and 12 months. Exercise level will be detected by validated questionnaire and compared between 2 arms at 3 and 12 months.

CONCLUSION

The trial will examine the efficacy of treating ND and HT by an exercise program.

The relationship between the carotid atherosclerosis ultrasound parameters and the cardiac and endothelial functions of coronary heart disease patients

PURPOSE

This study aimed to discover the relationship between the carotid atherosclerosis ultrasound parameters and the cardiac and endothelial functions of coronary heart disease patients.

METHODS

150 patients with coronary artery disease were divided into a single-branch group (one coronary artery with stenosis > 50%), a double-branch group (two coronary arteries with stenosis > 50%), and a multi-branch group (multiple coronary arteries with stenosis > 50%) based on the severity of each patient's coronary stenosis. Meanwhile, 50 healthy volunteers who were admitted to the hospital for routine health checks were recruited as the control group. This study tested the ultrasound parameters of carotid artery atherosclerosis among all the subjects in each group [common carotid artery sclerosis (β), carotid artery compliance (AC), elastic coefficient (Ep), pulse wave conduction velocity (PWVβ)], including the left ventricular end diastolic inner diameter (LVEDD), left ventricular ejection fraction (LVEF) and endothelial function parameters [endothelin-1 (ET-1), von Willebrand factor (vWF), and nitric oxide (NO)].

RESULTS

The study found that the β, AC, Ep, PWVβ, LVEDD, LVESD, ET-1, and vWF levels of patients with coronary artery disease were all higher than the corresponding levels in the control group (P < 0.05). The values increased as the number of coronary artery branches with stenosis increased (P < 0.05). The LVEF and NO of the patients with coronary artery disease were lower than they were in the control group (P < 0.05). The LVEF and NO decreased as the coronary artery branches with stenosis increased (P < 0.05). The correlation analysis indicated that the ultrasound parameter of carotid atherosclerosis has a significant positive relation with the LVEDD, LVESD, ET-1, and vWF levels (P < 0.05) and a negative relation with the LVEF and NO levels (P < 0.05).

CONCLUSION

The ultrasound parameter of carotid atherosclerosis, cardiac function, and endothelial function can be used for the early diagnosis of coronary heart disease.

The effectiveness of dialectical behavior therapy on adherence to treatment and self-caring behavior in patients with coronary heart disease

BACKGROUND

The aim of this study was to investigate the effectiveness of dialectical behavior therapy (DBT) on adherence to treatment and self-caring behavior in patients with coronary heart disease (CHD).

METHODS

This was an experimental study based on control and experimental groups with pre-test and post-test. 32 male and female patients with CHD having at least high school diploma, referring to Isfahan cardiovascular research institute, Isfahan, Iran, were selected and placed randomly in two groups of control and experimental. Pre-test stage was done for both two groups by 8-item Morisky Medication Adherence Scale (MMAS-8) and Self-Care of Coronary Heart Disease Inventory (SC-CHDI). The experimental group was placed under the intervention of DBT for 8 sessions of 2 hours (once a week). Afterwards, the post-test was done for both groups.

RESULTS

It was shown by analyzing results from t-test that adherence to treatment and self-care behavior significantly increased in experimental group comparing to control group [(1.81 ± 0.75 vs. 5.19 ± 1.22, P < 0.001) and (72.50 ± 4.38 vs. 55.50 ± 7.42, P < 0.001), respectively]. Also results showed that self-caring and adherence to treatment significantly increased after being adjusted for baseline measurement (P < 0.001). The findings showed that DBT had effect on adherence to treatment and self-caring behavior of patients with CHD.

CONCLUSION

On the basis of results, it could be said that DBT intervention can have positive impact on adherence to treatment and self-caring behavior of patients with CHD.

InVestiGation of the Association of Physical Activity and Sedentary Behavior with tHe Occurrence of Future Cardiovascular Disease and Long Term Outcome in General Population Using the HEALTHCARE Database (VGH-HEALTHCARE)

BACKGROUND

Current evidence supports the beneficial effect of physical activity in reducing adverse events, however studies on Asian populations are limited and have reported inconsistent findings. The aim of this study was to investigate the association between physical activity and the development of cardiovascular disease, diabetes, hypertension and malignancy in a large Asian cohort. We also investigated interactions between the intensity of physical activity, environmental exposure and biochemical markers.

METHODS

Subjects who received annual checkups at Taipei Veterans General Hospital were invited to join this study. Information on physical activity was evaluated using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Associations between the occurrence of clinical events including cardiovascular events, diabetes and malignancies and the intensity of physical activity, biochemical markers, imaging findings, personality trait evaluations and nutrition were evaluated.

RESULTS

In the initial stage of this study, a total of 1010 patients enrolled, 626 (62%) were male, 74 (7.4%) had diabetes, 183 (18.3%) had hypertension, and 220 (21.8%) were smokers. The total cholesterol was 202.1 ± 36.2 mg/dL and low-density lipoprotein-cholesterol was 125.7 ± 32.9 mg/dL, including 49.3 ± 13.1 mg/dL for serum high-density lipoprotein-cholesterol and 120.7 ± 70.7 mg/dL for triglycerides. The fasting glucose level was 93.8 ± 21.9 mg/dL, and HbA1c was 5.7 ± 0.7%. All information collected will be incorporated with future events to analyze the relationship between biochemical parameters, physical activity and future adverse events.

CONCLUSIONS

These findings will contribute to the understanding of the value of physical activity in determining future cardiovascular and non-cardiovascular events in Asian populations.

The Impact of Blood Pressure Dipping Status on Cognition, Mobility, and Cardiovascular Health in Older Adults Following an Exercise Program

Objectives: To determine whether a dual-task gait and aerobic exercise intervention differentially impacted older adults with normal blood pressure (BP) dipping status (dippers) compared to those with nondipping status (nondippers). Methods: This study was a secondary analysis involving participants (mean age = 70.3 years, 61% women) who attended a laboratory-based exercise intervention over a 6-month period (40 min/day and 3 days/week). Participants were assessed in measures of cognition, mobility, and cardiovascular health at baseline, 3, 6, and 12 months (after a 6-month no-contact follow-up). Results: We observed improvements in cognition in both groups at 6 and 12 months, although no between-group differences were seen. Nondippers demonstrated superior improvements in usual gait velocity and step length after the exercise intervention compared to dippers. Dippers reduced daytime systolic BP at 6 and 12 months to a greater extent than nondippers. Discussion: BP dipping status at baseline did not influence exercise benefits to cognition but did mediate changes in mobility and cardiovascular health.

Heme Oxygenase-1 Activity as a Correlate to Exercise-Mediated Amelioration of Cognitive Decline and Neuropathological Alterations in an Aging Rat Model of Dementia

Alzheimer's disease (AD) is a neurodegenerative disorder with cognitive impairment. Physical exercise has long been proven to be beneficial in the disorder. The present study was designed to examine the effect of voluntary exercise on spatial memory, imaging, and pathological abnormalities. Particular focus has been given to the role of heme oxygenase-1 (HO-1)—an important cellular cytoprotectant in preserving mental acuity—using an aging rat model of dementia. Male and female Wistar rats were segregated into six groups—namely, (i) aged sedentary (control) females (ASF, n = 8); (ii) aged sedentary (control) males (ASM, n = 8); (iii) aged running females (ARF, n = 8); (iv) aged running males (ARM, n = 8); (v) young control females (YCF, n = 8); and (vi) young control males (YCM, n = 8). Rats in the ARF and ARM groups had free access to a standardized inbuilt running wheel during the 3-month evaluation period. Spatial memory was investigated using the Morris Water Test, imaging and pathological alterations were assessed using positron emission tomography (PET) imaging and histopathological examinations (H&E, Congo red staining), respectively, and HO-1 enzyme activity assays were also conducted. The outcomes suggest that voluntary physical exercise mitigates impaired spatial memory and neuropathological changes exhibited by the aging sedentary group, via elevated HO-1 activity, contributing to the antioxidant capacity in the aging brain.

Advances in psychological interventions for lifestyle disorders: overview of interventions in cardiovascular disorder and type 2 diabetes mellitus

PURPOSE OF REVIEW

The present review examines the recent advances in psychological interventions for two major lifestyle disorders in adults namely, type 2 diabetes mellitus and cardiovascular disorders. The review summarizes findings from studies carried out between the years 2015 and 2017.

RECENT FINDINGS

The effectiveness of psychological interventions in the management of lifestyle disorders has been examined with respect to adaptation, self-care, adherence, negative emotions and improving quality of life. There is an increasing recognition that psychological interventions are important for prevention of lifestyle disorders and promotion of health. Key psychological interventions include self-management and educational interventions based on learning and motivational principles, patient empowerment, cognitive behaviour therapy, behavioural skills and coaching. Recent developments also include the use of information technology to deliver these interventions through internet, mobile applications and text messages. Another significant development is that of mindfulness-based interventions within the third-generation behaviour therapy approaches to reduce distress and increase acceptance. In addition, family and couples interventions have also been emphasised as necessary in maintenance of healthy behaviours.

SUMMARY

Studies examining psychological interventions in cardiovascular and type 2 diabetes mellitus support the efficacy of these interventions in bringing about changes in biochemical / physiological parameters and in psychological outcomes such as self-efficacy, knowledge, quality of life and a sense of empowerment.
