Cardiovascular disease can refer to a number of conditions:
Heart and blood vessel disease (also called heart disease) includes numerous problems, many of which are related to a process called atherosclerosis.
Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. This buildup narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can block the blood flow. This can cause a heart attack or stroke.
A heart attack occurs when the blood flow to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die.
Most people survive their first heart attack and return to their normal lives, enjoying many more years of productive activity. But experiencing a heart attack does mean that you need to make some changes.
The medications and lifestyle changes that your doctor recommends may vary according to how badly your heart was damaged, and to what degree of heart disease caused the heart attack.

An ischemic stroke (the most common type of stroke) occurs when a blood vessel that feeds the brain gets blocked, usually from a blood clot.
When the blood supply to a part of the brain is cut off, some brain cells will begin to die. This can result in the loss of functions controlled by that part of the brain, such as walking or talking.
A hemorrhagic stroke occurs when a blood vessel within the brain bursts. This is most often caused by uncontrolled hypertension (high blood pressure).
Some effects of stroke are permanent if too many brain cells die after being starved of oxygen. These cells are never replaced.
The good news is that sometimes brain cells don’t die during stroke — instead, the damage is temporary. Over time, as injured cells repair themselves, previously impaired function improves. (In other cases, undamaged brain cells nearby may take over for the areas of the brain that were injured.)
Either way, strength may return, speech may get better and memory may improve. This recovery process is what stroke rehabilitation is all about.
When it comes to spotting stroke and getting help, the faster, the better. That’s because prompt treatment may make the difference between life and death — or the difference between a full recovery and long-term disability. Use the letters in F.A.S.T to spot a stroke. F is for face drooping. A is for arm weakness. S is for speech difficulty. T is for time to call 911.

Heart disease, sometimes called congestive heart failure. Means the heart isn’t pumping blood as well as it should. Heart failing does not mean that the heart stops beating that’s a common misperception. Instead, the heart keeps working, but the body’s need for blood and oxygen isn’t being met.
Heart disease can get worse if left untreated. If your loved one has heart failure, it’s very important to follow the doctor’s orders.

Arrhythmia refers to an abnormal heart rhythm. There are various types of arrhythmias. The heart can beat too slow, too fast or irregularly.
Bradycardia, or a heart rate that’s too slow, is when the heart rate is less than 60 beats per minute. Tachycardia, or a heart rate that’s too fast, refers to a heart rate of more than 100 beats per minute.
An arrhythmia can affect how well your heart works. With an irregular heartbeat, your heart may not be able to pump enough blood to meet your body’s needs.

When heart valves don’t open enough to allow the blood to flow through as it should, a condition called stenosis results. When the heart valves don’t close properly and thus allow blood to leak through, it’s called regurgitation. If the valve leaflets bulge or prolapse back into the upper chamber, it’s a condition called prolapse. Discover more about the roles your heart valves play in healthy circulation.

Here are some common treatments for different types of cardiovascular disease:
In the hospital and during the first few weeks at home, the doctor may perform several tests and procedures. These tests help the doctor determine what caused the stroke or heart attack, and how much damage was done. Some tests monitor progress to see if treatment is working.

Learn more about surgical procedures that may have been performed at the hospital.
The medications prescribed in the wake of a cardiac event can aid in recovery and work to prevent another stroke or heart attack.
If you’re a caregiver, make it your responsibility to help your loved one take medications as directed and on time. Educate yourself about the medications that your loved one must take. Know what those medicines do, and what their goal is.
It’s important to follow your doctor’s directions closely, so ask questions and take notes. Learn more about cardiac medications.
