Beta blockers and mortality after a heart attack

Beta blockers after an acute myocardial infarction appear to reduce 30 day mortality. Discontinuation of beta blockers at one year in patients without heart failure or left ventricular dysfunction appears safe. BMJ. 2016 Sep 20;354:i4801

Comment: In patients without heart failure or left ventricular dysfunction, the early use of beta blockers appears to decrease mortality, but prolonged use after 1 year appears unlikely to improve long-term survival.

High-intensity interval training versus moderate-intensity continuous training in persons with elevated cardiovascular risk.

This review highlights advances in our understanding of high-intensity interval training compared to moderate-intensity continuous training. F1000Res. 2016 Sep 7;5. pii: F1000 Faculty Rev-2254.

Comment: More and more evidence is accumulating that high-intensity interval training results in greater benefits than moderate-intensity continuous training for the time spent training.

Economic Impact of Moderate-Vigorous Physical Activity Among Those With and Without Established Cardiovascular Disease: 2012 Medical Expenditure Panel Survey.

Moderate to vigorous physical activity for at least 30 minutes a day 5 days a week was found to be associated with significantly reduced health care spending. J Am Heart Assoc. 2016 Sep 7;5(9).

Comment: The key here seems to be that the exercise intensity was moderate to vigorous. Any activity is good, however, short bursts of intensity appear to be particularly beneficial.

Viewers vs. Doers. The relationship between watching food television and BMI.

Obtaining cooking information from television shows and social media was found to be associated with increased body weight. Cooking from scratch was also associated with increased weight. Obtaining cooking information from other print, online, or in-person sources was not significantly associated with body weight.  (Appetite. 2015 Jul 1;90:131-5.)

Therapies that appear to be helpful include patient-centered care, dementia care mapping, sensory therapy activities, and structured music therapies.  (Health Technol Assess. 2014 Jun;18(39):1-226, v-vi.)
