Silent heart attacks: Much more common than we thought in both men and women
We typically think of heart attacks as sudden, chest-clutching agony. But the reality is that nearly half of all heart attacks have no symptoms at all and go completely unnoticed by the people experiencing them — and, alarmingly, these “clinically silent” heart attacks are nearly identical to more overt heart attacks in terms of the damage they cause and the risk to a person’s future health.
Thyroid disorders and heart conditions: What’s the connection?
Watch for an irregular heartbeat and cardiovascular disease.
Thyroid disorders are often overlooked as potential causes of heart problems, but there is a well-established link.

The thyroid is a butterfly-shaped gland in your neck. It produces hormones—thyroxine (T4) and triiodothyronine (T3)—that tell your cells if they need to speed up or slow down. But if the thyroid gland is overactive or underactive, the result is a number of consequences and symptoms, sometimes involving the heart. "The connection to the heart is well established, but thyroid problems are often overlooked as the cause," says Dr. Giuseppe Barbesino, an endocrinologist at Harvard-affiliated Massachusetts General Hospital.
What to do about a high blood pressure diagnosis
A high blood pressure diagnosis can come as a shock due to a lack of symptoms, but the condition is manageable. Dr. Naomi Fisher explains what to do after you are diagnosed.
Cardiac rehab: Even better with stress reduction
Cardiac rehabilitation—a supervised program to help people recover after a heart attack or heart surgery—may be more helpful if it includes stress reduction training, according to a study published online March 21 in the journal Circulation.
Researchers compared three groups of heart patients: people who did cardiac rehab for 12 weeks, those who did cardiac rehab plus stress reduction, and those who chose not to participate in cardiac rehab. The stress reduction group engaged in weekly, 1.5 hour-long sessions that included small group discussions and training in stress reduction, coping skills, and relaxation techniques.
Drink more water to cut calories, fat, and sugar?
Increasing daily water intake by one, two, or three cups daily can help reduce total calorie intake and lower a person’s intake of saturated fat, sugar, sodium, and cholesterol.
Mammograms identify heart disease risk
Research We’re Watching

When specks of calcium appear in ductal tissue on mammograms, they can indicate a small cancer. But when calcifications are found in the breast arteries, they haven't been a cause for concern. However, in recent years, physicians have begun to suspect that arterial calcifications in the breast, like calcifications in the coronary arteries of the heart, can be an early sign of cardiovascular disease.
A team of researchers at Mount Sinai St. Luke's Medical Center in New York City studied the test results of 292 women who'd had digital mammography and non-contrast CT chest scans within a year. None of the women were known to have heart disease. They found that 42.5% of the women had evidence of breast artery calcifications on mammography, and of these, 70% also had evidence of coronary artery calcification on their CT scans. Moreover, 63% of those whose CT images revealed coronary artery calcifications had breast artery calcifications as well. Over all, the results indicated that women with breast artery calcifications are three times as likely as those who don't to have coronary artery calcifications. The study was published online March 24, 2016, by JACC Clinical Imaging.
