Heart Disease Information
Heart disease is a general term for a variety of diseases and conditions that affect heart function. The main job of the heart pumps blood through the body. The main concern of the conditions of the heart is much more than affecting the ability of the heart to pump blood. When people use the term heart-disease, often called atherosclerosis or blocked arteries. Blocked heart arteries cause heart disease or CAD. In turn, coronary artery disease can lead to:
Chest pain in the form of stable angina or unstable
Congestive heart failure, when the heart stops pumping enough blood to body tissues
Heart attack
Irregular heartbeats or arrhythmias
But heart disease can also refer to many others. It's important for people to remember when they see or hear the term heart disease. Heart disease is the main cause of death.
Understanding Heart Disease
What are the causes and risks of the disease?
There are many causes of heart disease. Atherosclerosis, or blockage of the arteries, is partly or wholly responsible for many diseases affecting the heart, including: Inadequate heart failure, a condition in which a weakened heart can not pump enough blood through the body.
Factors that increase the risk of person to develop atherosclerosis include:
Diabetes
Overweight and obesity
History Family of atherosclerosis or coronary artery disease
Hypertension
High levels of cholesterol
Increasing age
Lack of exercise
Smoking
High blood pressure can cause heart disease, even when the arteries are not blocked. High blood pressure can cause enlargement of the heart, known as hypertrophy and congestive heart failure. It also increases the risk of blocked arteries This can damage the heart.
Congenital heart disease, meaning that heart disease is present at birth, may cause a heart has abnormal structure or defect in the atrial septum is the function and / or ventricular septal defect. The conditions of the heart valves, as stenosis lung may be present at birth.
What are the signs and symptoms of the disease?
Symptoms depend on the cause, the severity and type of heart disease. Signs and symptoms of heart disease are:
Pain or chest discomfort
Cough
Cyanosis or bluish skin
Enlarged neck veins
Fainting or fainting
Loss of appetite and loss weight
Palpitations or an awareness of unusual heart beat
Shortness
Swollen leg
Weakness and fatigue
How is the disease diagnosed?
Heart disease is often suspected after a medical history and pass a physical examination is done. Other tests may be done to determine the type, severity and cause of heart disease. These may include:
Chest radiograph
Echocardiography, which uses sound waves to visualize the beating heart
Electrocardiogram or ECG, which shows activity heart's electrical
The exercise ECG test in which a person walks on a treadmill or receives a product, while considering effects on the heart with an electrocardiogram or a test image
Blood and urine
Angio CT, a special study in which a contrast agent is injected vein and CT is performed when the contrast agent passes through the coronary arteries.
Angiography coronary mini – invasive access to the coronary circulation and blood filled chambers of the heart by the cardiac catheter and a special x-ray made with a contrast agent to watch the heart and its blood supply.
What can be done to prevent the disease?
Preventing heart disease is linked to its question. Heart disease caused by atherosclerosis could be prevented by not smoking and controlling blood pressure, diabetes and cholesterol. Avoiding alcohol can prevent cases due to this cause. Maintain a healthy body weight, including physical activity in everyday life, and a diet to reduce heart disease minimum can help reduce the risk of heart disease.
What are the effects long term illness?
The long-term effects depend on the nature, severity and causes of heart disease. Heart attacks and inadequate heart failure are common causes of death. May heart infections disappear completely after treatment and have no effects long term.
What are the risks to others?
Heart disease is not contagious. Some causes of hereditary heart disease can be transmitted to children. If the underlying cause is infection, infection can be contagious.

Tim Russert enlarged heart – may or ultrasound imaging have been detected before?
"An autopsy determined Mr. Russert had an enlarged heart and significant coronary artery disease. "Does that mean they did not have regular health check? If not detected before it is too late? Then an ultrasound or other images you find an enlarged heart?
They have already reported that Russert had known coronary disease, but was "controlled" with medication and exercise. Sometimes, all the treatment in the world will not help you unless you change your diet. If rupture of the plate, he hit a really bad time. Their vessel may have been reduced. Many people have mild cardiac hypertrophy and not be dead at 58. His body associated with food and luck to create the perfect storm. An echocardiogram (ultrasound) or magnetic resonance imaging could demonstrate the problem. Even a standard chest radiography can detect cardiac hypertrophy probably obvious to the pathologist at autopsy. He probably had at least one of these tests, but one of the following occurred: – he had an enlarged heart at the time of the tests – the skill level of the physician's interpretation was too low to diagnosis – there was a problem with the quality of the evidence if you or a family member to be a study of the image, try to get at least one other physician types (who reads this type of study) to give a second opinion if possible, with the help of your insurance company or primary care physician.
