People who follow a healthy lifestyle can still have the early stages of coronary artery disease (CAD), the most common type of heart disease. There are many ways people can find out if they have CAD. This includes paying attention to whether exercise causes discomfort, doing a 10-year heart risk assessment, and seeing their doctor for diagnostic testing, such as a coronary artery calcium scan, a resting electrocardiogram, a walking stress test, or an echocardiogram. A doctor uses this information to determine the best treatment path.

Prostate cancer often develops quietly, with few or no early warning signs, and can resemble normal age‑related prostate changes. When symptoms arise, they usually involve subtle changes in urination. Doctors combine careful questioning, physical examination, blood tests, and modern scans to distinguish harmless enlargement from serious disease.

Heart palpitations are sensations of a pounding or racing heartbeat, often triggered by stress, stimulants, or hormonal changes. They're usually harmless but should be checked by a doctor. Palpitations may improve with lifestyle changes or treatment for underlying conditions.

Performed during an echocardiogram, a bubble study involves injecting a small amount of fluid filled with tiny bubbles into an arm vein. It can reveal the path of blood flow through the heart and provide clues about the cause of an unexpected stroke.
