Angina pectoris is the partial obstruction of the coronary arteries due to lack of oxygen. It can occur when the heart is forced to work harder and the body is unable to increase the blood flow to that organ, and the heart nerves transmit urgent pain signals to the brain. Angina pectoris is very common in men after the age of 30 and in women at a later age. The cause is atherosclerosis in most cases.
Angina is a symptom, not a disease. It is a direct result of the lack of blood in the heart muscle, which is known as ischemia. Unlike a myocardial infarction (heart muscle), an angina is due to temporary lack of oxygen and partially blocked blood vessels (coronary arteries). Infarction causes necrosis (death) of the myocardial cells and the coronary arteries are completely blocked.
The symptoms are:
Severe chest pain, acute and suffocating chest tightness, usually behind the breastbone and sometimes extended to the arm.
Strong feeling of anxiety, distress or imminent death.
Coronary angioplasty is a procedure to be performed when other drug treatments have not succeeded. It is performed in a hospital under general anesthesia and its goal is to clear the coronary arteries which are narrowed or clogged by cholesterol and/or thrombus (blood clot). The stent is a tube, often biodegradable, which can be permanent or temporary, and can be classified according to the organ or vessel where it is placed. It can be made of metal, plastic or biodegradable material in the shape of a mesh or spiral. It may be coated with medication.
Less invasive modern techniques such as endoscopy, interventional radiology and catheterization make possible the placement of these devices in anatomical tubular structures or conduits such as vessels, coronary arteries, femoral and aorta arteries. The most common and frequent technique is the intravascular coronary procedure that complements the angioplasty which came to replace revascularization, in most cases, through bridges or Bypass.
