Adding a little extra spice to your food may help you eat less salt, according to a study in the December 2017 issue of Hypertension. A salty diet may raise your risk of high blood pressure, leaving you more prone to heart attack and stroke.
For the study, Chinese researchers recruited 606 people and determined their preferences for salty and spicy foods, in part by asking how often they ate foods such as salted fried pork and pickled Chinese cabbage.
Weighing the risks and benefits of aspirin therapy

Maybe you've heard about people who take a low-dose aspirin each day to ward off heart problems. Since aspirin is a medicine you've probably used now and then without a problem, and since it is available without a prescription, you might consider trying a daily low-dose aspirin yourself. Don't do it. Unlike deciding to take a multivitamin, taking a daily aspirin isn't something you should decide to do on your own.
Aspirin therapy is typically prescribed to people who have atherosclerosis of the arteries of the heart or brain, or risk factors for such disease. Just who should take a daily aspirin, how much aspirin, and what type of aspirin are hotly debated issues, with clinical trials under way in search of answers. "Until those results are in, you should talk to your doctor before starting aspirin," says Dr. Deepak Bhatt, a cardiologist and the editor in chief of the Harvard Heart Letter.
Can shingles raise your risk for heart attack and stroke?
Research we're watching
A research letter published in the July 3 issue of the Journal of the American College of Cardiology says that shingles, a painful rash caused by the varicella-zoster virus (the same virus that causes chickenpox) may be linked to an increased risk of stroke and heart attack.
South Korean researchers used a national medical database to identify diagnoses of shingles, stroke, and heart attack and followed them from 2003 to 2013. They compared 23,213 individuals who had developed shingles during this period and compared their subsequent rates of heart attack and stroke to approximately 23,213 shingles-free individuals. They found that people who had shingles had a 35% higher risk of heart attack and a 59% higher risk of stroke.
Shingles may raise heart attack risk

People who develop the painful, blistering rash known as shingles may be more susceptible to a heart attack, according to a study in the July 11, 2017, Journal of the American College of Cardiology. Also known as herpes zoster, shingles results from a reactivation of the virus that causes chickenpox, which most adults had during childhood.
Researchers relied on a Korean health database to identify people newly diagnosed with shingles, stroke, or heart attack over 10 years. Among the nearly 520,000 people they followed for that period, just over 23,000 were diagnosed with shingles, whom they compared with a similar number of people without shingles. People who'd had shingles had a 59% higher risk of later having a heart attack and a 35% higher risk of having a stroke compared with people who did not have shingles. The risk was highest during the first year after the onset of shingles and then diminished over time.
The push you need to learn CPR
After calling 911, do you know what to do if a person is unresponsive and not breathing?

Each year, an estimated 600,000 Americans suffer a cardiac arrest, during which the heart suddenly and unexpectedly stops beating. If someone nearby immediately begins cardiopulmonary resuscitation (CPR), the chest compressions can keep blood flowing to the person's brain and other vital organs — and more than double the odds of survival.
"About 70% of cardiac arrests happen at home. If this happened to your spouse or loved one, wouldn't it be awful if you didn't know what to do?" says Dr. Charles Pozner, associate professor of emergency medicine at Harvard-affiliated Brigham and Women's Hospital. But only 18% of adults in the United States have been trained in CPR within the past two years, according to a recent nationwide survey of 9,022 people, published in the May 24, 2017, Journal of the American Heart Association.
Pain relievers and heart attack risk

Heart attack risk may rise within a week of taking daily high doses of certain over-the-counter pain relievers, according to a new study.
Previous research has linked the use of pain relievers known as nonsteroidal anti-inflammatory drugs (NSAIDs) to a heightened risk of heart attack. The new report, published in the May 9, 2017, issue of The BMJ, analyzed data from nearly half a million people, of whom about 61,000 had heart attacks.
How steak and eggs may increase heart attack risk

New research may help explain why diets rich in animal-based foods are linked to a higher risk of heart attack.
The average American diet contains about 300 milligrams per day of choline, a nutrient found in meat, eggs, and milk. Earlier research found that when gut bacteria feed on choline, they make a compound called TMA. In the liver, TMA is converted to TMAO — a compound closely tied to heart disease risk.
Do premature heart attacks run in your family?
If so, be extra vigilant about measuring and managing your blood pressure and cholesterol.
Filling out those family history forms at the doctor's office can be tedious. But sometimes, the devil is in those details. Because heart disease is so common, many people check "yes" to the question about whether their father or mother had heart disease. But if your father had a heart attack at age 77, that's likely different than if his heart attack happened when he was only 44.
"If you have any family history of heart disease, that should serve as a keen reminder to pay attention to factors that can raise your risk of a heart attack, such as high cholesterol, high blood pressure, and diabetes," says Dr. Howard Sesso, an epidemiologist with the division of preventive medicine at Harvard-affiliated Brigham and Women's Hospital. But if a parent or sibling had a premature heart attack, that's an even stronger signal to be more proactive in monitoring and lowering your risk, he adds. A premature or early heart attack is one that occurs before age 55 in a man or before age 65 in a woman.
Aspirin therapy may not lower heart attack risk for those with type 2 diabetes
In the journals
Low-dose aspirin therapy is standard treatment for people who have suffered a heart attack or stroke to protect them from a second one. But what about people who don't have cardiovascular disease, but do have specific risk factors, such as type 2 diabetes? A study published in the Feb. 14, 2017, Circulation found that low-dose aspirin therapy in fact did not lower this group's risk for heart attack or stroke.
The researchers recruited more than 2,500 people, ages 30 to 85, with type 2 diabetes and randomly assigned them to take either 81 mg or 100 mg of aspirin daily, or no aspirin, for three years. At the 10-year follow-up, they found that the aspirin therapy did not lower risk of either heart attack or stroke compared with taking no aspirin at all. The reason is not clear, but the researchers speculated that people with diabetes might not experience the expected anti-clotting action of aspirin.
Implanted defibrillators in older people: What to expect
Research we're watching
Implantable cardioverter-defibrillators (ICDs) are miniature electronic devices placed under the skin below the collarbone to sense and stop abnormal heart rhythms. A study in the Jan. 24, 2017, Journal of the American College of Cardiology provides new information about outcomes in older people who receive these lifesaving devices.
The study included 12,420 people with an average age of 75. All had survived a sudden cardiac arrest and received an ICD. Nearly four in five of the participants survived at least two years. During the two-year period, nearly 65% were hospitalized at some point. Many were admitted to skilled nursing facilities during the study, including about 32% of those ages 80 and older.
