Adopting a healthy lifestyle, along with ongoing care and emotional support, may help you prevent or delay atherosclerosis and the problems it can cause.

Carotid artery disease may not cause signs or symptoms until it severely narrows or blocks a carotid artery. Signs and symptoms may include a bruit, a transient ischemic attack (TIA), or a stroke. It is important to call 9–1–1 for emergency help if you think you are having a TIA or stroke.

Your doctor will diagnose carotid artery disease based on your medical history, a physical exam, and results from one or more tests: ultrasound, angiography, magnetic resonance angiography (MRA), and computed tomography (CT) angiography.

Doctors diagnose a stroke by reviewing your signs and symptoms, medical history, physical exam, and results from one or more tests: brain computed tomography (CT) scan, magnetic resonance imaging (MRI), CT or magnetic resonance arteriogram, carotid ultrasound, carotid angiography, electrocardiogram (EKG), echocardiography, and blood tests.

To diagnose hypersensitivity pneumonitis, your doctor will collect your medical history, assess exposure history to possible causative substances, perform a physical exam, and possibly order diagnostic tests and procedures such as: blood tests, bronchoalveolar lavage (BAL), computed tomography (CT), inhalation challenge tests, lung biopsies, lung function tests, precipitin tests, or chest x-rays.

Regular physical activity can help you lose excess weight; improve physical fitness; lower many heart disease risk factors such as “bad” LDL cholesterol levels, increase “good” HDL cholesterol levels, and manage high blood pressure; lower stress and improve your mental health; and lower your risk for other conditions such as type 2 diabetes, depression, and cancer. Even modest amounts of physical activity are good for your health.
