A 2025 study suggested that women with diabetes are nearly twice as likely as men to have hidden heart disease. These women might especially benefit from early screening for problems in the small blood vessels of the heart.

Many people with atrial fibrillation (afib) - a rapid, irregular heart rhythm - need to control symptoms, such as the feeling that the heart is racing or fluttering. Medication options include drugs that slow down the heart or help restore its rhythm. Because afib can also increase the risk of blood clots that can lead to a stroke, many of these people also need to take clot-preventing medications.

A type of artificial intelligence that uses a deep machine learning tool to analyze different features from routine mammograms can predict a woman's risk of heart-related problems, according to a 2025 analysis.

A free online tool that estimates your heart's age suggests that most adults have a heart that is older than their chronological age, according to a 2025 study.

Heart rate variability (HRV) is a measure of the tiny fluctuations in timing from one heartbeat to the next. Higher values are linked to better fitness levels and stress resilience.

A 2025 study suggests that higher fitness levels may help protect people from developing atrial fibrillation.

Exercise is one of the most powerful tools for preventing heart disease and extending life. Physical activity triggers favorable changes such as making cells more sensitive to insulin and reducing inflammation. It also helps keep blood vessels supple and flexible (which supports efficient blood flow), strengthens muscles (which helps burn more calories), and remodels the heart, making it more efficient at pumping blood through the body. Together, these changes all reduce a person's chances of developing common risk factors for heart disease, including diabetes, high blood pressure, high cholesterol, and obesity.

A 2025 study finds that smoking and high blood pressure are the two most important factors driving heart disease risk. Together with high cholesterol, excess weight (or being underweight), and diabetes, these five factors account for about 50% of the burden of cardiovascular disease. Compared to people with all five risk factors at age 50, those who had none of the factors were far less likely to develop cardiovascular disease or die early. On average, women with none of the risks at midlife lived 13 more years without heart disease, while men lived an additional 11 years.

For some people with atrial fibrillation, cold drinks and foods can trigger a bout of the rapid, irregular heartbeat that characterizes the disorder. Avoiding those triggers nearly always prevents this phenomenon, dubbed "cold drink heart."
