Complications

Flu shots and heart disease

If you have heart disease, flu shots can reduce your risk of flu-related complications that could worsen your condition. Find out why.

Symptoms

Fatigue

Fatigue can signal many things. Here are some tips to help you decipher why you're wiped out and to regain your energy.

Heart murmurs

Heart palpitations

Heart palpitations are skipped, fluttering or racing heartbeats that aren't usually a symptom of a serious heart problem. Discover the causes and symptoms of this condition.

Shortness of breath

Shortness of breath can be frightening. Most of the time, a heart or lung condition is the cause.

Tests and diagnosis

Cardiac catheterization

Cardiac catheterization is used as a test for some heart conditions and as a procedure to treat some types of heart disease. Find out more.

Chest X-rays

Echocardiogram

Echocardiogram allows your doctor to see your heart in motion. Here's what you need to know about the test.

Electrocardiogram

An electrocardiogram (ECG or EKG) is a test that provides valuable clues about your heart health. Here's what you need to know about the test.
