An US randomized crossover study showed that chronic dietary red meat increases systemic trimethylamine N-oxide (TMAO) levels through enhanced dietary precursors, increased microbial trimethylamine (TMA)/TMAO production from carnitine, but not choline, and reduced renal TMAO excretion. Discontinuation of dietary red meat reduces plasma TMAO within 4 weeks. There were 113 healthy […]
A prospective global cohort study suggested that total sleep duration of 6–8 h per day is associated with the lowest risk of deaths and major cardiovascular events (MCEs). Daytime napping is associated with increased risks of MCEs and deaths in those with >6 h of nighttime sleep but not in those sleeping […]
The U.S. Food and Drug Administration (FDA) responded to a petition for a new qualified health claim for edible oils containing high levels of oleic acid, a monounsaturated fat that’s been shown to have cardiovascular benefits when it replaces heart-damaging saturated fat. Manufacturers of these oils can choose to include […]
A nationwide, randomized, placebo-controlled trial revealed that daily supplementation with high-dose vitamin D or n-3 fatty acids for 5 years among initially healthy adults in the US did not reduce the incidence of cancer or the incidence of major cardiovascular events. The trial included 25,871 participants (5106 black, ages >/=50 […]
An UK prospective population based cohort study found that genetic and lifestyle factors were independently associated with risk of incident stroke. The study recruited 306 473 men and women, aged 40-73 years, between 2006 and 2010. During a median follow-up of 7.1 years (2 138 443 person years), 2077 incident strokes (1541 ischemic […]
A population based cohort study in the UK showed that the use of angiotensin converting enzyme inhibitors (ACEIs) was associated with an increased risk of lung cancer. The association was particularly elevated among people using ACEIs for more than five years. The cohort of 992 061 patients newly treated with antihypertensive […]
A prospective, population-based and nationwide Swedish study revealed that low air temperature, low atmospheric air pressure, high wind velocity, and shorter sunshine duration were associated with risk of myocardial infarction (MI) with the most evident association observed for air temperature. A total of 280 873 patients were included from 1998 […]
A population-based, prospective cohort study in Iceland revealed that the long-term mortality risk of unrecognized myocardial infarction (UMI) can be as high as clinically recognized myocardial infarction (RMI). 935 participants (aged 67-93 years, 48.3% men) were characterized with cardiac magnetic resonance (CMR) from January 2004 to January 2007 and followed […]
Findings of two randomized, placebo controlled clinical trials challenged the role of aspirin in primary prevention in a low-risk population and in patients of diabetes. A randomized, double-blind, placebo-controlled, multicenter study was done in seven countries. Between July 5, 2007, and Nov 15, 2016, 12 546 eligible patients aged 55 years […]
Major world cardiology associations have updated and standardized what defines a heart attack and have added the concept of “myocardial injury.” Myocardial injury is defined as an elevated cardiac troponin. The myocardial injury is considered acute if there is rise and/or fall of troponin values. Acute myocardial infarction is defined […]
