Conquer your fear of dietary fat

For decades, high intake of fat was thought to cause weight gain, heart disease, and maybe even cancer. The solution? Go low-fat, which often meant consuming more carbs and more sugar. But nutritionists now suggest people actually need adequate amounts of "good" unsaturated fat, and less "bad" saturated fat, for optimal health. Following popular heart-healthy diets, like the Mediterranean and MIND diets, and making simple dietary changes can help people get adequate amounts of good fats.

Should I get a calcium score?

A coronary artery calcium scan (often called a calcium scan) uses a special type of CT scan to look for calcium deposits in the lining of the heart's arteries. The results can help people decide whether to start taking a statin.

Air pollution: An invisible threat to your heart

Exposure to microscopic particles called PM2.5 in air pollution may increase a person’s risk of heart attack, stroke, and heart rhythm disorders. The tiny particles pass from the lungs into the bloodstream, triggering inflammation and other cell-damaging processes. Air pollution comes mainly from coal-fired power plants, industrial factories, and motor vehicles. To limit exposure, people should try to avoid exercising outdoors near busy roads or industrial areas.

Feel woozy? Do this first

People who’ve never experienced wooziness should call 911 if the symptom comes on suddenly or severely, especially if it’s accompanied by other symptoms. However, a person who has experienced wooziness before or been unwell recently should sit down, have a drink of water or juice, and rest for 10 to 15 minutes. If the feeling of wooziness persists, if other symptoms develop, or if it’s hard to get up without feeling faint, one should call 911.

Harvard study: Shingles linked to a spike in risks for heart attack and stroke

A 2022 observational study that included more than 200,000 people found that those who'd had shingles at some point had a 30% higher long-term risk for a major cardiovascular event, compared with people who didn't have shingles.

Spot the warning signs of 4 dangerous conditions

Sometimes people miss the symptoms of life-threatening conditions such as a heart attack, a stroke, atrial fibrillation, or a pulmonary embolism. To detect the warning signs, people should pay attention to sudden, new symptoms, especially if they include shortness of breath, chest pain, heart palpitations, lightheadedness, confusion, weakness, fatigue, fainting, or a terrible headache. Someone experiencing any of these symptoms should call 911. If symptoms aren't sudden or intense, and people aren't sure if they warrant emergency help, they should call their doctor.

Stopping unneeded aspirin may prevent dangerous bleeding

Some people who take the anti-clotting drug warfarin (Coumadin) may not need to take low-dose aspirin. Stopping unneeded aspirin use may prevent dangerous bleeding.

Ready to learn CPR?

When a person's heart stops beating and they go into cardiac arrest, receiving CPR can double their odds of surviving. And since the majority of cardiac arrests happen at home, knowing the basics of CPR may save the life of a loved one.

Gout linked with risk for heart attack and stroke

Gout strikes when too much uric acid builds up in the body and triggers severe pain, swelling, and redness in one or more joints, often in the big toe. New research suggests that an episode may increase the risk for a heart attack or stroke over the following two months.

Poor physical function may predict cardiovascular disease

A new study suggests that older adults who maintain an high level functional fitness have a lower their risk of heart attack, heart failure, and stroke compared with those who are not as fit.
