Cardiovascular is made up of the words "cardio" meaning heart and "vascular" meaning blood vessels. Cardiovascular disease (CVD) thus encompasses diseases of the heart and diseases of the blood vessels. CVD includes angina (chest pain), myocardial infarction (heart attack), and stroke.
Anything that injures the heart, making it less able to function properly, is a disease of the heart. Often the various types are grouped according to whether the dysfunction is congenital (i.e., inborn or present at birth) or acquired (e.g., due to another disease or condition).
The most common disease in the industrialized world and the number one killer of Canadians is coronary heart disease (CHD), also sometimes called CAD, coronary artery disease. It is a disease of the arteries that supply blood to the heart muscle that can lead to heart attacks. When people speak of heart disease, they are usually talking about CHD.
Some people with cardiovascular disease don't realize it, especially in the early stages, but most people have some indication. Common symptoms include:
The symptoms experienced by some women may be different from those of men; they include indigestion-like discomfort, nausea, back pain.
Most acquired cardiovascular diseases are caused by atherosclerosis which occurs when fatty buildups of plaque narrow the arteries, thus slowing blood flow to the heart.
If you think you may have CVD, visit your doctor as soon as possible. Besides taking a thorough medical history and carrying out a physical examination, your doctor will probably follow up with some tests. Diagnostic tests include blood tests, electrocardiograms (ECGs), echocardiograms (an ultrasound of the heart), chest X-rays, dynamic stress tests (using a treadmill), and tests involving nuclear medicine studies (MUGA scan) that use radioactive material injected into your vein to see how your heart is functioning. Another helpful diagnostic tool is the Holter monitor, a small box the size of a pocket book that's really just an ECG. You wear it for about 24 hours as you go about your day and it records how your heart is behaving.
When someone is diagnosed with cardiovascular disease, it often means that the person has more than one problem. Frequently the primary heart problem leads to other problems, all of them worsening each other. This is what happens with high blood pressure: It can lead to coronary heart disease, congestive heart failure, heart attack, stroke, and damage to vital organs such as the kidneys and eyes. Early diagnosis of CVD means that treatment can intervene before other diseases can develop.
There are certain things that make you more likely to develop heart disease; some of them you can change, and some you can't:
Doctors today have a broad range of medications at their disposal for the treatment of cardiovascular disease. Other treatment options include surgical procedures such as angioplasty and bypass surgery, valve replacement, pacemaker installation, and heart transplantation.
But the most important treatments for cardiovascular disease usually involve lifestyle changes that only you can implement. At the top of the list are diet and exercise. Ask your doctor to help you put together an achievable program to become healthier. You may be referred to a nutritionist or dietician for advice on what to eat - and not eat. Many community health centres offer specialized exercise programs to help people with heart problems get in shape as well as support groups for dealing with the limitations created by the cardiovascular disease.
You can reduce your risk of cardiovascular disease if you:
