Hypertensia pressure and atherosclerosis
Atherosclerosis is a scourge of the 20 th century. A factor is the pressure of their hypertensia progress. In a breach of atherosclerosis, the balance of blood lipids showed increasing levels of LDL and lower levels of high density lipoprotein is marked. It leads to the formation of the vascular wall, called plaque, which will consist of various salts of calcium, the fibrin fibers and cholesterol. And, in turn, leads to decrease the brightness of vessels, and most seriously regard vessels of the heart (coronary arteries) that cause disease and ischemic heart attack, myocardial infarction, and vessels of the brain that are designated as infringements of the bloodstream and brain damage.
Sample of atherosclerosis
Atherosclerosis abroad generally not displayed in any way to narrowed vessels will not reach that level where the blood flow in organs and tissues have been seriously depleted. For example, can be a pain behind Brest, related to physical activity, and sometimes at rest, pain in the finitude that are also related to a reduction of the arteries.
Heart attack of myocardial perfusion
Crises cardiac infarction is a condition in which a thigh heart – myocardium – there is a serious failure of blood circulation due to the glow plug of a complete coronary atherosclerotic plaque or a blood clot (which occurs less frequently). In the absence of circulation for some time in a network myocardial necrosis, which is already irreversible. In this necrosis was then replaced by scar material.
Diagnosis of atherosclerosis
Atherosclerosis usually comes to light only when the conditions caused by it are marked: one stenocardia an attack of heart attack, insult, infringement of blood circulation in finitude. Diagnosis of atherosclerosis is based on the following research methods
* The electrocardiogram. It This method is based on records the electrical activity heart. As we talked, the heart is a system to pass an electrical impulse passes unit which forms the other muscles. These potentials reflect the work heart. In particular pathology, an electrocardiogram or other attributes are marked. This particularly affects anisorhythmia, events ischemic attacks, which are characteristic of a heart attack, myocardial infarction.
* Ergometry cycling. This approach also relies on an electrocardiogram, but conducted under load when the patient receives a physical activity for free access. Due to the load demand at heart blood supply amplified, and is not visible from the availability of cleft defects in the blood to the heart.
* Coronary. These methods of radiological diagnosis of coronary vessels to introduce a catheter, often long and thin, enter a brachial or femoral artery. After reaching a catheter into the coronary artery is contained in their opaque medium. After the x-ray image This will be the sites of narrowing of the arteries of the plaque is made.
* An echocardiogram (ultrasound of the heart). This method can reveal structural changes of heart, for example, a thickening of the ventricular walls, talking about their hypertrophy. It is one of the signs a hypertensia pressure.
* The CT. It is a radiological method that can receive level by level in the heart sections tissue.
* The procedure imaging by magnetic resonance. The method can also receive up level by level in tissue sections, especially the boats because it is very sensitive. But there is an x-ray method in which electromagnetic waves are applied firmly to a magnet in a field.
Treatment of atherosclerosis
The treatment of atherosclerosis include, first, the change of regime food, exercise, and preparations for reducing levels of cholesterol in the blood. A concern of surgical angioplasty procedures first ball, where one plate lightning fell from a vessel a catheter is inserted long, thin cartridge Inflation at the end then the flash of an artery that extends, and a stent, when in a flash of an artery called stent is established, playing a portion of a skeleton ship. In some cases, other interventions, for example, are devoted to maneuver.
