Different types of rapid heart rhythms

Atrial fibrillation and supraventricular tachycardia are rapid, abnormal heart rhythms that originate in the upper part of the heart. But they tend to arise at different ages, and they require different treatments.

Gratitude enhances health, brings happiness � and may even lengthen lives

Gratitude has the power to boost well-being, improve sleep, lessen depression, and help heart health. Now new data from the long-term Nurses' Health Study shows that it may extend lives. How can you jump start a gratitude practice in your life?

Body roundness may beat body mass for identifying risky fat

Body roundness index, which is calculated based on a person's height, waist, and hip size, might be a more accurate measurement than body mass index for predicting weight-related health risks, according to a 2024 study.

Should you really take that daily aspirin?

A 2024 analysis found that many people without heart problems are taking daily low-dose aspirin therapy, even though it might have more health risks than benefits. Some of them have not consulted with a doctor about whether daily aspirin is safe for them.

When fear strikes the heart: Post-traumatic stress disorder

People with post-traumatic stress disorder (PTSD) are especially vulnerable to cardiovascular problems, including a 40% increased risk of heart attack. The amygdala, a brain structure involved in processing anxiety, fear, and stress, is overactive in people with PTSD. But these people also have decreased activity in the ventromedial prefrontal cortex, which is responsible for regulating emotions and dampening the fear response. This brain activity imbalance triggers chronic activation of the body's "fight-or-flight" response. The resulting physiological changes appear to underlie the development of atherosclerosis.

A brief bout of anger may be bad for your blood vessels

A short episode of anger may have adverse effects on the cells lining the blood vessels, according to a 2024 study. The findings may help explain the long-observed link between negative emotions and an increased likelihood of cardiovascular problems.

Chemical pollutants: A growing concern for your heart

Chemical pollutants such as lead, perfluoroalkyl and polyfluoroalkyl substances (also known as PFAS), and pesticides may contribute to heart disease risk. Possible routes of exposure for all three include drinking water and food. Residue and dust from many common items (such as water-resistant clothing and personal care products) may expose people to PFAS. People can limit their exposure by testing and, if needed, filtering their drinking water; choosing PFAS-free products when possible; using non-chemical pest control methods; and choosing organic foods.

Another risk related to atrial fibrillation

A 2024 study suggests that for people with atrial fibrillation (afib), heart failure may be a more common complication than stroke. People with afib should be vigilant for the early warning signs of heart failure, such as feeling tired and winded.

Low testosterone levels linked to shorter life span

In a 2024 study of men ages 49 to 76, low levels of testosterone were associated with higher rates of death from any cause and specifically deaths from cardiovascular causes, such as heart attack, cardiac arrest, heart failure, or stroke.
