A message for men who want a healthy heart…and why some people should test their blood pressure at home.
People who show normal blood pressure readings in the doctor's office and elevated readings at home have an increased risk of heart attack.   Doctors call the condition masked hypertension and say people with it are more likely to be male, smoke or have a history of cardiovascular disease.  People at risk of masked hypertension should closely monitor their blood pressure at home.
Not all FDA trials for new drugs are the same.   A new study published in JAMA shows a wide variation in the evidence used when federal health officials approve new medications.  Researchers found that experimental trials vary in size, design and duration.  They say the flexible approach can be beneficial, allowing fast approval of life-saving drugs.
California researchers have a simple message for men looking to prevent heart problems:  be active and sit less.   In a new study, they found the risk of heart failure more than doubled for men who sat for at least 5 hours a day and got little exercise.  That's compared to active men who sat less than 2 hours a day.  The American Heart Association recommends that men and women get at least 150 minutes of moderate aerobic exercise each week.
