According to new research, nearly half of all heart attacks are 'silent', with symptoms appearing so mild that they are barely noticed. Silent heart attacks increase the risk of dying from heart disease and other causes, and can be as deadly as those with classic symptoms.
A study of 90,000 nurses found that high fruit consumption during adolescence was associated with a 25% lower risk of breast cancer diagnosed in middle age. Increasing alcohol intake in later life was linked to a higher risk of breast cancer and heart disease.
Researchers found that HDL is not uniformly predictive of cardiovascular risk, with triglycerides and LDL modifying the incidence of CVD in both low- and high-level HDL. High levels of LDL or TG can increase cardiovascular risk by 30-60% compared to isolated low HDL.
Medical errors are a leading cause of death in the US, with estimates suggesting 210,000 to 400,000 deaths per year among hospital patients. Experts call for better reporting and strategies to reduce medical errors, including making errors more visible and having remedies at hand.
A study of over 189,000 initially healthy women found that working rotating night shifts for 5 years or more was associated with a small increase in coronary heart disease risk. The researchers also discovered waning risk after cessation of shift work and decreased risk among those who quit earlier.
Researchers found that women who worked rotating night shifts for five or more years had a 15-18% increased risk of developing coronary heart disease. Changing shift schedules may help offset this risk, which is modifiable and important to note.
