Angina

Is known as coronary heart disease any disorder caused by a restricci’re in the blood supply to the m&number;muscle cardíaco. The manifestations más currents are angina pectoris and myocardial infarction. Angina is a sísevere clínico discomfort torácica transient, with painful crises s&number;bitts, and difficulty breathing as a result of the increase in demand miocárdica of oxígeno and the coronary stenosis.

The manifestations más currents are angina pectoris and myocardial infarction. Angina is a sísevere clínico discomfort torácica transient, with painful crises s&number;bitts, and difficulty breathing as a result of the increase in demand miocárdica of oxígeno and the coronary stenosis. 

Títypically, the angina begins with a sore atenazante or oppressive by detrás del estern’n, which may radiate to the neck and the mandíbula, or towards the left arm. The pain refers to ráquickly with the rest. The strong emotions or the fríor may determine that it is not necessary a great effort to cause the angina.

TERM ANGINA

téterm «angina» it comes from latín «angor pectoris», and means «constriction in the chest». Patients who suffer from angina often say they feel a feeling’re choking, or president’n or a burning sensation in the chest, but an episode of angina is not an attack cardíaco. The pain often appears after effort físico. Unlike an attack on the heart,’n, m&number;muscle cardíaco does not suffer a da&bath;or permanent and the pain usually goes away with rest. 

&are you;C&Number;AT IS THE CAUSE OF ANGINA pectoris? 

angina is the pain that occurs when a coronary artery to diseased coronary arteries are the vessels sanguíneos that supply blood to the heart’n) can not deliver enough blood to a part of the heart’n to satisfy their need for oxígeno. The contribution of poor blood rich in oxígeno to the heart’re called «ischemia». Angina usually occurs when the heart’n have a greater need of blood rich in oxígeno, for example, during the year, físico. Other triggers include strong emotions, extreme temperatures, heavy meals, alcohol, and tobacco.

In men, angina attacks usually occur afterés of the 30 to&years of age and are almost always caused by a disease of the arteries and coronary artery disease (CAD). In women, angina tends to occur at an older age and can result from several conditions. Causes apart from the CAD is the narrowing of the vávalve to the’rtica in the heart’n (stenosis’rtica), a low level of gl’red blood cells in the stream sanguínea (anemia) or a glágland overactive thyroid (hyperthyroidism).

&are you;CUÁTHEM ARE THE S&Rsquo;SYMPTOMS?

angina is usually a síntoma of coronary artery disease (CAD). People who suffer from angina have an increased likelihood of suffering an attack cardíaco than those that do not have s’symptoms of CAD.

The angina tends to start in the center of the chest, but the pain can spread to the left arm, the neck or the mandíbula. It is possible to suffer numbness or péloss of sensation in the arms, shoulders or mu&bath;rct. The episodes usually last s’what a few minutes. If the pain lasts for más of a few minutes, you couldíto be a sudden obstrucci’n total of a coronary artery or an attack cardíaco.

There are different types of angina. Patients with stable angina usually know the level of activity or estrés which causes an attack. Patients alsoén must remember cuánto tiempo duran attacks, if new attacks feel different than a previous attack and if they are relieved with medications. Sometimes changes occur in the attacks: strike with greater frequency, duran más time, or occur when the person has not exercised. A change in the mode of the attacks can’to mean that the patient suffers from what is called «unstable angina», in which case it is important to consult the médico as soon as possible. Patients who feel a new pain, worse, or constant chest have a higher risk of suffering an attack cardíaco, an irregularity of the heartbeat (arrhythmia) and even a death s&number;bita.

OTHER TYPES OF ANGINA

angina variant or Prinzmetal’s angina is a type of angina little com&number;n caused by what is called the «coronary spasm» (vasospasm). The spasm close momentásimultaneously the coronary artery preventing the heart’re getting enough blood. Can occur in patients who have además a acumulaci’re significant of fatty plaque (atherosclerosis) in at least one glass of sanguíneo important. Unlike angina típica, angina variant usually appears in moments of rest. These attacks can be very painful and tend to occur primarily between midnight and 8 of the ma&bath;ana. Often occur every díto at the same time.

angina microvascular is a type of angina in which patients feel pain in the chest but don’t seem to have any obstrucci’re in the coronary arteries. Feel pain in the chest because the small&years vessels sanguíneos that feed the heart’n, the arms and legs do not function normally. Patients tend to cope with this type of angina and have very few long-term side effects.

&are you;C&Rsquo;MO WAS DIAGNOSED with ANGINA?

méphysicians can usually determine if a patient suffers from angina basáon s’symptoms éste described and their frequency, length’n and intensity. Studies can be undertaken such as radiografías, an electrocardiogram (ECG) at rest and during and afterés of exercise, a stress test with is’moles and a angiograf’to coronary artery disease.

angina variant can be diagnosed using a Holter monitor. Studies Holter allow to obtain a continuous reading of frequency and rate cardíaco during a space of 24 hours or the más. The patient wears a device for recording’n (the Holter monitor), which is connected to small branches;os disks of metal called «electrodes», which are placed on the chest. With certain types of monitors, the patient can press a bot’n of recording’ve to catch the rhythm, cardíaco at the time of the feel of the sísymptoms of angina.

&are you;C&Rsquo;MO IS ANGINA?

The medicines and changes in lifestyle are the means of más com&number;commonly used to control angina. In the case más serious, couldíto be necessary to perform a procedure called «revascularizaci’n».

Changes in the style of life

Although angina can be caused by the exercise físico, this does not mean that the patient should stop exercising, but you must follow an exercise program approved by the médico. Should be checked the risk factors of EAC (títypically atherosclerosis), among them the hipertensi’n blood, the consumption of cigarettes, high cholesterol levels and excess weight. If the patient eats a healthy diet, not smoke, limit your consumption of alcohol, and avoid the estrés, couldá live más c’modamente and suffer from attacks of angina with a lower frequency.

Medicines

Certain medications may help to prevent or relieve s’symptoms of angina. The más known is nitroglycerin, which, by reducing the pressure’n blood, you can help relax arteries and keep them open or dilated. Nitroglycerin act&number;in question’n of seconds. In general, it is indicated to patients who sit or lie down in as suffer an attack, and then take your nitroglycerin. If an activity such as climbing stairs causes angina, the patient may take the nitroglycerin before the activity, to avoid an attack.

Other medications used to control angina típica and angina microvascular are the beta-blockers and-blockers cálcicos. These medications reduce the demand for oxígeno on the part of the heart’n to reduce the frequency cardíaca or the president’n arterial. Alsoén reduce the likelihood that the patient suffers from an irregularity in the beats of the heart’n (arrhythmia). Blockers cálcicos and nitrates alsoén can be used to prevent the spasms that cause the angina variant.

For patients who suffer from unstable angina, the méphysicians usually suggest bed rest and alg&number;n type of blood thinner, such as heparin.

surgery, laser treatment’and interventions elapsedatéter

If an angina típica or an angina variant is caused by a CAD severe, it may be necessary to perform a procedure of revascularizaci’n to improve the blood supply to the heart,’no. The revascularizaci’n can be performed by using a hand’n transcatéter or a surgery, laser treatment’to bypass.
