Coronary computed tomography angiography (CCTA) creates a 3D image of the heart and its blood vessels, revealing both obstructive and nonobstructive plaque. Most heart attacks occur when smaller, nonobstructive plaques rupture and form a clot that triggers a heart attack. Used to assess people with stable angina, CCTA may prevent heart attacks by improving how cardiologists find and treat heart disease.

With ticks thriving in a wider geographic range, appearing earlier and sticking around later, it's important to stay vigilant about protecting yourself against ticks that cause Lyme disease and other illnesses. Learn some steps you can take to avoid tick bites.

Long-term research found that higher consumption of butter increases mortality risk, while higher consumption of plant-based oil lowers it. And substituting certain plant oils for butter might help people live longer. What's a butter lover to do?

A free online database provides nutrition facts, ingredient information, and a score that reflects the level of processing for more than 50,000 products at three major supermarkets.

Most people don't need to fast before a lipid test because the difference between LDL cholesterol values when fasting or not fasting is very small. But people who have had high triglyceride levels should fast prior to the test.

Engaging in prosocial, altruistic behavior that benefits other people-such as doing volunteer work, giving money to charity, or performing small acts of kindness-may be beneficial to cardiovascular health. Possible mechanisms include reductions in stress and blood pressure. Volunteering has also been associated with improvements in heart-related risks, including increased step counts and less depression.

Leg pain may be caused by deep-vein thrombosis (DVT), a blood clot that forms in a deep vein, usually in the leg. Left untreated, the clot may break off, travel to the lungs, and cause blockage in a lung artery, known as pulmonary embolism (PE), which can be life threatening. Diagnosis of DVT and PE may include a review of symptoms, a D-dimer blood test, a leg ultrasound, or a chest CT scan. Both conditions are most often treated with direct-acting oral anticoagulants.

Using tobacco in cigars, pipes, or smokeless products such as snuff is associated with distinct heart-related risks.

Intensive blood pressure control that lowers systolic blood pressure (the first number in a reading) below 120 points may lower the risk of cognitive impairment or probable dementia.
