Benefits of exercise training on blood pressure and beyond in cardiovascular diseases

Cardiac events and economic burden among patients with hypertension and treated insomnia in the USA

Background: Cardiovascular (CV) event risk, healthcare resource utilization (HCRU) and costs have not been elucidated among hypertension patients with treated insomnia (H + TI). Materials & methods: Adult patients with H + TI were identified in IBM MarketScan databases. H + TI patients were matched 1:1 on age and sex to controls with hypertension but without sleep disorders. Multivariable models were used to estimate associations between treated insomnia and CV event risk, HCRU and costs. Results: In total, 81,502 H + TI patients (mean age = 62 years, 53% female) were matched. Relative to controls, H + TI patients were 2.4 times as likely to have CV events. H + TI patients incurred higher costs per patient per month (US$2343 vs US$1013). Conclusion: Treated insomnia was associated with higher costs and HRCU in hypertension patients.

Do the combined blood pressure effects of exercise and antihypertensive medications add up to the sum of their parts? A systematic meta-review

Objective

To compare the blood pressure (BP) effects of exercise alone (EXalone), medication alone (MEDSalone) and combined (EX+MEDScombined) among adults with hypertension.

Data sources

PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus and the Cochrane Library.

Eligibility criteria

Randomised controlled trails (RCTs) or meta-analyses (MAs) of controlled trials that: (1) involved healthy adults>18 year with hypertension; (2) investigated exercise and BP; (3) reported preintervention and postintervention BP and (4) were published in English. RCTs had an EX+MEDScombined arm; and an EXalone arm and/or an MEDSalone arm; and MAs performed moderator analyses.

Design

A systematic network MA and meta-review with the evidence graded using the Physical Activity Guidelines for Americans Advisory Committee system.

Outcome

The BP response for EXalone, MEDSalone and EX+MEDScombined and compared with each other.

Results

Twelve RCTs qualified with 342 subjects (60% women) who were mostly physically inactive, middle-aged to older adults. There were 13 qualifying MAs with 28 468 participants (~50% women) who were mostly Caucasian or Asian. Most RCTs were aerobic (83.3%), while the MAs involved traditional (46%) and alternative (54%) exercise types. Strong evidence demonstrates EXalone, MEDSalone and EX+MEDScombined reduce BP and EX+MEDScombined elicit BP reductions less than the sum of their parts. Strong evidence indicates EX+MEDScombined potentiate the BP effects of MEDSalone. Although the evidence is stronger for alternative than traditional types of exercise, EXaloneelicits greater BP reductions than MEDSalone.

Conclusions

The combined BP effects of exercise and medications are not additive or synergistic, but when combined they bolster the antihypertensive effects of MEDSalone.

Effects of aerobic training with and without progression on blood pressure in patients with type 2 diabetes: A systematic review with meta-analyses and meta-regressions

AIMS

To analyze the effects of aerobic training with and without progression on blood pressure in patients with type 2 diabetes.

METHODS

The databases used for the systematic search were PubMed, Cochrane Central, SPORTDiscus and LILACS. Studies which analyzed blood pressure before and after an intervention period of eight or more weeks of aerobic training compared to a control group without training in patients with type 2 diabetes were included.

RESULTS

Of the 4186 studies found, 17 clinical trials were included (912 participants). Systolic blood pressure (SBP) decreased after aerobic training with progression (-6.78 mmHg; 95% CI -8.36, -5.19; p < 0.001) and without progression (-8.07 mmHg; 95% CI -9.37, -6.77; p < 0.001). The same happened regarding diastolic blood pressure (DBP), which decreased with aerobic training with progression (-3.10 mmHg; 95% CI -4.90, -1.31; p < 0.001) and without progression (-5.71 mmHg; 95% CI -7.15, -4.28; p < 0.001).

CONCLUSION

Aerobic training is effective in reducing blood pressure in patients with type 2 diabetes, regardless of progression in training variables.
