A new study on thyroid functionality may prove helpful for doctors to decide when to treat people with an underactive thyroid gland that doesn’t have any worrying symptoms.

Almost 27 million people in the US have some sort of thyroid problem and more than half of these people have not been diagnosed with the disease, the American Association of Clinical Endocrinologists says.

According to Dr. Anne R. Cappola, who is an assistant professor of medicine and epidemiology at the University of Pennsylvania, “At this point, it is not clear how to manage older people with subclinical thyroid dysfunction.” The findings of the study will be published in the Journal of the American College of Cardiology in its Sept.30 issue.

According to a new study conducted by the Harvard University researchers, air pollution causes to hamper heart’s ability in conducting electrical signals. The researchers noticed worrying changes on the heart traces of 48 heart patients because of small particulates exposure.

Many studies have already pointed out that particulate pollution is a cause of increasing heart attack risk. The circulation study seems to support these previous studies.

The researchers studied the electrocardiograms of 48 patients who were hospitalized because of heart attack and worsening symptoms of coronary heart disease. The researchers noticed some unusual changes on the heart traces that were known as St-segment depression.

NEW YORK - According to Australian researchers if diabetes is treated aggressively, it can be the guarantee to put off heart problems and deaths better than standard treatment that is used to lower blood sugar.

It was the second large study (as thousands of patients were involved in it) that showed no heart benefit from significantly decreasing blood sugar levels of the diabetics. Experts opined that doctors must follow the suggested aimed levels.

Almost two-third of diabetics die of heart disease. The researchers attempted to push down blood sugar to usual levels to notice whether it protected the hearts of high-risk patients with Type 2 diabetes or not.
