Diseases And Conditions Affecting The Heart

Anatomy of the Heart

Inflammation of Heart Tissue

Rheumatic heart diseaseis caused by streptococcal infection, affecting mostly the young children. Toxins that inflected by a pathogen can cause systemic immune reaction leading to rheumatic fever. It is usually occur 2-4 weeks after the infection.The immune reaction caused by pathogen can inflamed the endocardium, this called rheumatic endocarditis. Rheumatic endocarditis inflamed the valves specifically the bicuspid valve, and become incompetent or stenosed. Antibiotic is the effective medication to treat streptococcal infection.

MyocarditisIt is a myocardial infection where the inflammation if focus in myocardium and can lead to heart failure and sudden death.

EndocarditisIt is an endocardial infection affect mostly the valves especially the bicuspid valve, causing valve to become incompetent.

PericarditisThe infection is either result from a viral or bacterial pathogen. Pericardium is the site of inflammation which characterized an extreme painful sensation.

Condition Cause to reduced Blood Flow to Cardiac Muscle

Coronary heart diseaseprimarily reduces the blood production from the coronary arteries to myocardium. The insufficient blood flow can damage the myocardium. As age increase the wall of the arteries thicken and harden caused the blood supply decrease, and the capacity of the heart to pump blood decrease as well. Poor blood circulation in the heart caused cellular death resulting to aginapectoriswhere the pain sensation can extremely radiate to left arm, left shoulder and epigastria area. Coronary thrombosis also contributes to blood flow reduction because it is a form of blood clot in coronary blood vessel. An area of cardiac tissue that has been damage by insufficient blood flow is termed as infarct. The outcome usually depends on the extent of cellular death in the cardiac muscle and weather the other blood vessels can sustain amount of blood to maintain the heart functions. In most cases, the portion that has infarct normally replaced by a scar tissue. Patient can survi ve from infarction can often live normally if they take precautions. Moderate exercise with adequate rest, proper diet and stress reduction are frequently advice by health care provider. Aspirin and other medication are commonly administer to reduce high blood pressure appear to protect against the development of infarction.

Congenital Conditions Affecting the Hearth

Congenital heart disease is occurring at birth and result to abnormal development. Here are the following common congenital heart diseases:

Septal Defectis in two forms, the atrial septal defect and ventricular septal defect which allowing blood to flow from one side of the heart to the other side and causing to reduce the heart ability to pump.

Patent DuctusArteriosusis occurs when ductusarteriosus fail to close after birth. Ductusarteriosus in the fetus allowing blood flow from pulmonary trunk to the aorta of the heart, thus by passing the lung, and it will normally close after birth.

Stenosis of the Heart Valvesis an opening through one or more of the valves. Is in two forms the mitral valve stenosis and aortic valve stenosis.

Cyanosisis a usual sign of inadequate heart function in babies. This congenital heart disease is termed as blue baby referred to infant with cyanosis. This is caused by low oxygen level in the blood specifically in the peripheral blood vessels.
