CDC figures show that 165,393Trusted Source people died from cerebrovascular disease in 2022. Stroke is the most common type of cerebrovascular disease.

- numbness or weakness in the face, arm, or leg, usually affecting just one side of the body
- confusion
- difficulty speaking or understanding others
- vision problems
- dizziness, problems walking, loss of balance, or a lack of coordination
- a severe headache
There are three main typesTrusted Source of stroke. Two require immediate, emergency medical attention, while the other may resolve without treatment.
Ischemic stroke
An ischemic stroke happens when a clot blocks the vessel that takes blood to the brain. It requires emergency medical attention. A doctor may use drugs to break up the clot.
Hemorrhagic stroke
A hemorrhagic stroke occurs when a blood vessel bursts in the brain. It requires urgent medical attention, usually in the form of an operation. Surgeons can repair the burst vessel with a metal clip.
Transient ischemic attack (TIA)
TIA is when blood flow to the brain is inadequate for a short period. Normal blood flow usually resumes shortly afterward. For many people, the symptoms resolve without treatment. This is sometimes called a ministroke.
5. Chronic lower respiratory disease
A total of 147,382 people died from chronic lower respiratory disease in 2022. Chronic lower respiratory disease refers to a group of conditions that affect the lungs.

Pulmonary hypertension is the term for high blood pressure in the arteries that deliver blood to the lungs. Over time, vessels become hard and narrow, meaning that the heart must work harder to pump the blood through them. Pulmonary hypertension can lead to heart failure.
The common symptoms include:
- shortness of breath
- feeling tired
