Deans' stroke musings: GW25-e0837 Effects of tea intake on blood pressure: a meta-analysis of 21 randomized controlled trials

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

GW25-e0837 Effects of tea intake on blood pressure: a meta-analysis of 21 randomized controlled trials

You'll have to ask your doctor what you need to do about your blood pressure. Ask for the protocol. Because if we don't start demanding protocols our doctors will never write one up. That is because they probably still believe in the incredibly stupid comment, 'All strokes are different, all stroke recoveries are different'. Challenge them on that and ask for published research. Or are they just pulling crap out of thin air because they need to say something to sound knowledgeable.

The effect of tea intake on blood pressure (BP) is controversial. We undertook a meta-analysis of randomized controlled trials to determine changes in systolic and diastolic BP due to the intake black and green tea.

Methods

Objectives | Methods | Results | Conclusions

MEDLINE, EMBASE, and the Cochrane Controlled Trials Register were searched from 1966 until January 2014 for studies in parallel group or crossover design in which BP was assessed before and after receiving black or green tea for at least 1 week. The weighted mean difference was calculated for net changes in BP by using fixed-effects or random-effects models. Previously defined subgroup analyses were performed to explore the influence of study characteristics.

Results

Objectives | Methods | Results | Conclusions

21 eligible randomized controlled trials with 1323 subjects were enrolled. After the tea intake, the pooled mean systolic and diastolic BP were −1.8 mmHg (95% confidence interval [CI], −2.4- −1.1 mmHg) and −1.4mmHg (95% CI, −2.2- −0.6 mm Hg) lower, respectively, compared with the tea-free controls. Subgroup analyses showed that the BP-lowering effect was apparent in the subjects who consumed a tea over a median of 12 weeks (systolic/diastolic BP, -2.6/-2.1 mmHg, both P <0.001). Stratified by type of tea, green tea significantly reduced systolic and diastolic BP of -2.1 (95% CI, −2.9- −1.2) and -1.7 (95% CI, −2.9- −0.5) mm Hg, and black tea significantly reduced systolic and diastolic BP of -1.4 (95% CI, −2.4- −0.4) and -1.1 (95% CI, -1.9- −0.2) mm Hg, respectively. The benefits of tea intake were not influenced by ethnicity, treatment dose of tea catechins, individual health status, or caffeine intake.
