This condition occurs when blood flow to a part of your heart is blocked for a long enough time that part of the heart muscle is damaged or dies. This is caused by decreased or complete cessation of blood flow to a portion of the myocardium. The lack of blood flow can damage or destroy part of the heart muscle. Treatment will include medications, Coronary angioplasty surgery, coronary bypass surgery, and cardiac rehabilitation.

This condition occurs when blood pressure is regularly 140/90 or higher.

If this is left untreated it will increase the risk of heart attack, stroke and other serious health problems. Most people with this condition have no symptoms, even if blood pressure readings reach dangerously high levels. Treatment is to make lifestyle changes and medications.

This condition occurs when blood pressure is regularly 90/60 or lower. This may not cause noticeable symptoms in some, or it could cause dizziness and fainting. Sometimes this can be life threatening. This condition may be caused from dehydration to serious medical conditions.

This condition results in hardening and narrowing of the arteries. This is a result of the buildup of fats, cholesterol, and other substances in and on your artery walls. This condition interferes with the normal workings of your cardiovascular system and may lead to coronary artery disease, heart attacks, and strokes.

This condition occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. It happens when the brain's blood vessels become narrowed or blocked, causing severely reduced blood flow. Brain cells begin to die in minutes so this is a medical emergency and prompt treatment is crucial.

This disorder refers to abnormal heart rates and rhythms. This condition occurs when the electrical signals that tell the heart to beat don't work properly. The heart can beat too fast, too slowly, or with an irregular rhythm. When a heart beats too fast, the condition is called tachycardia. When a heart beats too slowly, the condition is called bradycardia. This condition may feel like a fluttering, pounding or racing heartbeat. Some forms of this condition are harmless while others may cause life-threatening symptoms. Treatment may include medicines, devices such as pacemakers, or a procedure or surgery.

This disorder is a term used to describe a heart that cannot keep up with its workload and is not pumping as well as it should. The body depends on the heart’s pumping action to deliver oxygen- and nutrient-rich blood to the body’s cells and with this condition the weakened heart cannot supply the cells with enough blood. This results in fatigue and shortness of breath, and some people experience excessive coughing. Everyday activities such as walking, climbing stairs or carrying groceries can become very difficult. Surgeries and medications may help with some types of this, but severe forms may need a donor heart.

This disorder is a problem of not having enough healthy red blood cells or hemoglobin to carry oxygen to the body's tissues. This can cause tiredness, weakness and shortness of breath. There are many forms of this and each type has its own cause. This may be a warning sign of a serious illness. Treatments for this condition might involve taking supplements or having medical procedures.

This disorder is a cancer of the blood, characterized by the rapid growth of abnormal blood cells. It begins in cells in the bone marrow. There are many types of this disorder with some being more common in children and some more common in adults. Treatments for this condition depend on the type of this disorder that the person has, their age and overall health, and if it has spread to other organs or tissues.

This condition is a rare genetic disorder in which the blood doesn't clot in the typical way because it doesn't have enough blood-clotting proteins (clotting factors). People that have this condition might bleed for a longer time after an injury than they would if their blood clotted properly. Treatment includes regular replacement of the specific clotting factor that is reduced.
