Women in the highest quartile for light physical activity--more than 5.6 hours per day--had a 32% lower risk of
coronary heart disease than those in the lowest quartile of activity, who engaged in less than 3.9 hours per day, after adjusting for factors such as comorbidities, lifestyle, and cardiovascular risk.
Coronary heart disease occurs when your heart's blood supply is blocked or interrupted by a build-up of fatty substances in the arteries.
Therefore, the researchers say it is unclear whether the increased risk of heart failure,

The researchers found that the underlying pathoanatomic substrate was comorbid
coronary heart disease and cardiomegaly/left ventricular hypertrophy in 82 percent of cardiac cases.
A coronary angiography is the most conventional diagnostic method of
coronary heart disease in China.
In addition, total testosterone levels were associated with increased cardiovascular disease and
coronary heart disease, while estradiol is associated with a reduced risk of
coronary heart disease and heart failure with reduced ejection fraction, investigators reported in the Journal of the American College of Cardiology.
360,000 people a year are killed by
coronary heart disease.
For the study, published in the American Heart Association's journal Circulation, the researchers took women aged between 27-44 and found that women with the highest level of light physical activity were at a 25 per cent lower risk incidence of
coronary heart disease.
For subjects whose serum magnesium was categorized as low, there was a 36% higher risk of
coronary heart disease mortality and a 54% greater risk of sudden cardiac death in comparison with those who had levels in the middle range.
Working more than the standard 35- to 40-hour work week could increase a person's risk of stroke and
coronary heart disease, found a study published in August in The Lancet.
