Understanding silent heart attacks
Nearly half of all heart attacks are silent, meaning they are not associated with any reported symptoms. Silent heart attacks, which can be detected on electrocardiograms, should prompt people to follow the same prevention steps as with a more typical heart attack.
Why you should always have aspirin on hand
This old standby may not be your first choice for pain relief, but it still has an important role in disease prevention and first aid.

We have a lot to thank aspirin for. It's cheap and plentiful. It does a good job of relieving pain and bringing down fevers. It has also been shown to reduce the risk of heart attack, stroke, and colon cancer. It can even stop heart attacks and strokes in their tracks. In fact, if you're in your 50s or 60s, you may want to think about taking a low-dose aspirin every day.
After evaluating the results of scores of studies, in April 2016 the U.S. Preventive Services Task Force (USPSTF) recommended that women and men ages 50 through 69 who have a 10% risk of a heart attack or stroke in the next 10 years take 81 milligrams (mg) of aspirin daily. Under the previous recommendations—which, were different for men and women—daily low-dose aspirin was advised for women ages 60 through 79 who were at increased risk for cardiovascular events. The recommendation was revised to reflect a new method of calculating the risk of heart attack and stroke and of increased risk of bleeding in older people.
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.
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.
While waiting for your flight, learn how to save a life
Research we're watching

If your summer vacation plans include a stop at one of the nation's major airline hubs, you can put your waiting time to good use by learning cardiopulmonary resuscitation (CPR). The American Heart Association and the Anthem Foundation partnered to provide interactive training kiosks that teach people how to perform hands-only CPR in just five minutes. The pilot kiosk program at the Dallas/Fort Worth International Airport has trained more than 25,000 people so far.
The training includes a short a "how-to" video followed by a practice session on a rubber torso. You'll receive feedback about proper hand placement and the correct depth and rate of chest compressions—factors that influence the effectiveness of CPR. More than 20% of the estimated 359,000 cardiac arrests that occur outside the hospital each year happen in public places like airports, casinos, and sporting facilities.
The heart attack gender gap
Heart attacks strike men at younger ages than women. But survival rates are worse in women. Why?
Compared with men, women are less likely to recognize and act upon the symptoms of a heart attack.

Imagine someone in the throes of a heart attack. If you picture a man clutching his chest in agony, that's understandable. At younger ages, men face a greater risk of heart disease than women. On average, a first heart attack—the most common manifestation of this prevalent disease—strikes men at age 65. For women, the average age of a first heart attack is 72.
The benefits of positive thinking after a heart attack

A heart attack or unstable angina (sudden chest pain that happens at rest) usually requires a hospital stay. After such events—which doctors call acute coronary syndromes—about one in five people ends up back in the hospital with heart disease or dies in the following year. But there's a bright side: new research suggests that survivors with an optimistic attitude are less likely to be readmitted to the hospital with heart problems.
The study, published in the January 2016 Circulation: Cardiovascular Quality and Outcomes, included 164 people, mostly men, who were hospitalized for acute coronary syndromes. Two weeks after the event, they filled out questionnaires designed to measure their sense of optimism and gratitude.
Heart attack and stroke risk may rise briefly after a bout of shingles
A painful, blistering rash known as shingles may temporarily increase a person's risk of a stroke or heart attack, according to a study in the Dec. 15, 2015 PLOS Medicine. Also known as herpes zoster, shingles results from a reactivation of the virus that causes chickenpox, which most adults had during childhood.
For the study, researchers analyzed the records of more than 67,000 people ages 65 and older diagnosed with shingles and either a heart attack or stroke from 2006 through 2011. They then compared the rates of cardiovascular events before and after a shingles attack. In the first week after a shingles diagnosis, the risk of a stroke rose 2.4 times and the risk of a heart attack increased 1.7 times compared with baseline risk.
Don't ignore signs of sudden cardiac arrest
You may assume that there aren't any symptoms for sudden cardiac arrest (SCA), the deadly condition that occurs when your heart suddenly stops pumping. But a study published Jan. 5, 2016, in Annals of Internal Medicine suggests that warning signs are common and often ignored. The most common warning signs were chest pain, breathlessness, palpitations, lightheadedness or fainting, nausea, and vomiting.
Researchers looked at the health information of more than 800 people who experienced SCA, mostly middle-aged men, and discovered that about half of the people had warning signs during the four weeks leading up to SCA and even 24 hours before their hearts stopped. But most of those with warning signs ignored the symptoms. Thirty-two percent of those who called 911 before SCA survived, compared with only 6% among those who didn't call for help. That's because many of the symptoms that led people to call 911 occurred in the hours just before the SCA, so these people were likely to be in a medical care setting when their hearts stopped.
Heart attack survivors can have sex without fear
Sex does not appear to trigger a heart attack or increase your risk for a second one, suggests a study in the Sept. 21, 2015, issue of the Journal of the American College of Cardiology.
Experts looked at 536 heart attack survivors ages 30 to 70 and evaluated their sexual activity in the 12 months prior to their heart attack. Sexual activity was divided into three categories: less than once a month, less than once a week, and once or more per week.
