Heart Disease

Heart Disease

How ill If There's Disease in the Human Body. How ill, if you have heart disease. Surely we feel is the pain and discomfort. Heart attack (myocardial infarction), (myocardial infarct), (myocardial infarction) is a state where all of a sudden happen restriction or termination of blood flow to the heart, which causes the heart muscle (myocardium) to die from lack of oxygen.

Causes of heart attack usually occurs when a blockage in the coronary arteries results in limited or cut off blood flow to a part of the heart. If the interruption or reduction of blood flow lasts more than a few minutes, then the heart tissue will die.

Pumping ability of heart after a heart attack is directly related to the extent and location of tissue damage (infarct). If more than half of the damaged heart tissue, usually the heart can not function and the possibility of death. Even though the damage was not extensive, the heart can not pump properly, resulting in heart failure or shock.

Damaged heart can be enlarged, and partly an attempt to compensate for cardiac pumping ability is decreased (due to a larger heart will beat more powerful). The enlarged heart is also a picture of the damage to heart muscle itself. Enlargement of the heart after a heart attack give poorer prognosis.

Other causes of heart attack are:

• A clot from the heart itself. Sometimes a clot (embolus) formed in the heart, then broke and stuck in the coronary arteries.
• Spasm in the coronary arteries that causes cessation of blood flow. Seizures can be caused by drugs (like cocaine) or because of smoking, but sometimes the cause is unknown.

Symptoms of heart attack:

About 2 of 3 people who have heart attacks, a few days before the occurrence of chest pain attacks of relapsing-remitting, shortness of breath or fatigue. Chest pain more often arise even after a mild physical activity. Unstable angina like this could end up being a heart attack.

At mid-chest pain radiating to the back, jaw or left arm, or more rarely spreads to the right arm. Pain may occur in places without chest pain at all.

Pain in heart attacks more severe and longer, is not relieved by rest or administration nitroglliserin. Sometimes the pain is felt in the abdomen and be mistaken as one meal, especially because after burping pain sufferers somewhat diminished or disappeared for a while.

Other symptoms are feeling like going to faint and palpitations. Abnormal heart rhythms (arrhythmias) can affect the heart's pumping ability or may lead to cardiac arrest (heart stops pumping effectively), resulting in loss of consciousness or death.

During the attack, the patient may feel restless, anxious and sweaty and could feel his death will come soon enough. Lips, hands and feet appear bluish. Elderly patients can be disoriented (dazed).

As many as 1 in 5 people who have heart attacks, have only mild symptoms or no symptoms at all. Heart attack like this could only be identified from routine ECG examination some time later.

Frequent complication is myocardial rupture, blood clots, arrhythmia (heart rhythm disorder), heart failure or shock, or pericarditis.

If a man above 35 years old or above 50 years old woman complaining of chest pain, usually considered the possibility of a heart attack.

Diagnosis of heart attacks could be strengthened by performing the following checks:

• ECG

When a suspected heart attack, then the initial ECG is diagnostic examination of the most important.

Some abnormalities can be seen on the ECG, depending on the size and location of heart damage.

• Blood tests

Blood tests performed to determine the levels of certain enzymes.

CK-MB enzyme normally found in heart muscle and is released into the blood when heart damage occurs. Elevated levels of this enzyme would appear within 6 hours after a heart attack and persist for 36-48 hours. Levels of these enzymes are usually checked at the time of patient admission and every 6-8 hours during the next 24 hours.

• Echocardiogram

Echocardiogram will describe the reduced movement of a portion of the wall of the left ventricle (heart chamber that pumps blood throughout the body), which is an indication of damage from a heart attack.

• Radionuclide imaging.

The depiction of the radionuclides could indicate reduced blood flow to one part of the heart muscle, which is indicative of scar tissue (dead tissue) from a heart attack.

If you experience signs of heart attack as above it should be the prevention and treatment of heart attacks.
