Warning and precautions for sudden angina

Angina (angina diphtheria) is a feeling of pain or pressure in the chest, caused by ischemia (a lack of blood supply and thus inbound oxygen) in the heart muscle, usually as a result of blockage or spasms in the coronary arteries (vessels feeding the heart muscle). While angina may stem from anemia, arrhythmia or heart failure, the main cause of angina is coronary heart disease and is caused by atherosclerosis in the arteries of the heart.

There is a weak relationship between the severity of the pain and the degree of hypoxia in the heart muscle (that is, there can be severe pain with very little or no risk of myocardial infarction (heart attack) and heart attacks can occur without pain at all). Sometimes, angina can be very severe, and in the early 20th century angina was known as a sign of impending death.

The heart muscle acts as a pump to deliver blood to all parts of the body and the heart muscle gets the energy it needs (oxygen) to perform that task through the blood it reaches through the three arteries that feed it called coronary or coronary arteries, and angina are the symptoms that occur to the patient when Reduced blood prevalence in coronary arteries supplying the heart muscles, due to an imbalance between the heart’s consumption of food and the percentage of food reaching it.

Stable angina

Also called effort-related angina, this angina refers to the classic angina associated with ischemic heart muscle. A typical symptom of stable angina is chest discomfort, various symptoms after physical activity (such as running, walking, etc.) and very few or even no symptoms at rest or after taking nitroglycerin under the tongue.

Unstable angina

Unstable angina occurs even at rest that differs from the feeling of regular angina and is unexpected.

It is more dangerous and lasts longer than stable angina, as it may last for 30 minutes.

It does not necessarily disappear after resting, or after taking medications to treat angina.

It may indicate a heart attack.

Symptoms

Characteristic pain in the left side of the chest and behind the sternum. The pain is of the compressive type. It may extend to the left shoulder, lower neck and lower jaw, to the left hand and sometimes it may extend to the back or upper abdomen. There is a semi-permanent characteristic in most cases, which is the occurrence of pain with effort and its removal End of effort or rest. There are of course many other causes of chest pain, so it is necessary to consult a doctor immediately for some other examination.

The main diseases that cause blockage of the arteries of the heart and consequently angina are diseases of atherosclerosis, increased harmful cholesterol, diabetes and high blood pressure. The passage of blood may completely stop in one of the branches of the arteries of the heart due to the clotting that occurs in the narrow parts of it, so the blood stops completely from feeding this part of the muscle and the muscle dies, and this is known as myocardial infarction - where symptoms differ with what happens when angina For a long time it may occur at times of rest and sometimes when sleeping with associated feelings of nausea and profuse sweat or may appear indigestion and cause a feeling of extreme cold.

Causes of angina

One of the main causes of angina is the accumulation of fatty substances (cholesterol) on the coronary artery wall, which begins at an early age before adulthood. With continued fatty deposits with complications within this sediment, including bleeding, ulceration, and calcification, which results in his eventual residence, such as angina, as can occur as a cerebral angina that may lead to death or rickets.

Severe narrowing of the arteries or complete blockage, which leads to the appearance of symptoms, and there are risk factors that lead to the rapid occurrence of atherosclerosis, such as age and sex. "It occurs more in males than females, especially before menopause."

There is also a high level of harmful cholesterol (more than 200 mg / dl of blood), high blood pressure and smoking which are a major role in the occurrence of angina, and there are other secondary factors, including low density of high-density lipoprotein in the blood, the occurrence of coronary atherosclerosis In the family, especially at a young age, diabetes, obesity or obesity, reduced mobility and some types of mental or psychological stress.

And the high level of cholesterol in the blood means the proportion of total fats in the blood, and they differ according to the different eating habits between peoples, their percentage increases in people who eat a lot of animal food and much less in people who eat vegetable foods.

Studies and research have proven that high cholesterol increases the risk of arteriosclerosis and the rate of infection rises whenever the cholesterol level increases in the blood (it is recommended that the cholesterol level is less than 200 mg / dl of blood). High blood pressure (more than 140/75) is an important risk factor for angina due to the irregularity in blood flow within the artery, which causes changes inside the lining of the artery wall and increases coronary arteriosclerosis, and high blood pressure increases the work of the left ventricle and leads To swell and increase the need for oxygen.

Scientific research has demonstrated beyond any doubt that the risk of death resulting from blockage of the arteries of the heart increases by up to (70%) annually in smokers than in non-smokers, and that the percentage of sudden death in smokers annually is more than twice that of non-smokers. Smoking leads to increased blood platelet adhesion or arterial contraction due to nicotine, which has a strong astringent effect. It also leads to a decrease in the oxygen content as a result of inhaling carbon monoxide in cigarettes. Scientific studies have shown that the risk of smoking on coronary arteries is less by abstaining completely from Smoking or babysitting.
