Causes Of Heart Attack – Atherosclerosis

What causes a heart attack?

Atherosclerosis

Atherosclerosis is a gradual process which plaques (collections) of cholesterol deposited on artery walls. Cholesterol plaques cause hardening of the arterial wall and narrowing of the inner channel (lumen) artery. Arteries, which reduced atherosclerosis can not supply enough blood to maintain normal function of body parts of their supply. For example, atherosclerosis of the arteries of the legs causes reduced blood flow to the legs. Reduced blood flow in the legs can cause leg pain during walking or exercise, leg ulcers, or delayed healing of wounds on their feet. Atherosclerosis of the arteries, which are the blood in the brain, can lead to vascular dementia (mental deterioration due to progressive loss of brain tissue for many years) or stroke (sudden death of brain tissue).

In many people, atherosclerosis can remain silent (causing no symptoms or health problems), for many years or decades. Atherosclerosis may start already in adolescence, but symptoms or health problems usually do not occur later in adulthood, when the narrowing of the arteries becomes severe. Cigarette smoking, hypertension, high cholesterol, diabetes, and can accelerate atherosclerosis and lead to symptoms and complications before, especially in people who have a family history of early atherosclerosis.

Coronary atherosclerosis (or coronary artery disease) refers to the fact that the cause of atherosclerosis hardening and narrowing of the coronary arteries. Diseases caused by reduced blood supply to the heart muscle from coronary atherosclerosis called coronary heart disease (CHD). Coronary heart disease includes heart attacks, sudden unexpected death, chest pain (angina), abnormal heart rhythm and heart failure due to the weakening of the heart muscle.

atherosclerosis and angina

Angina (also called angina) is chest pain or pressure that occurs when blood and oxygen to the heart muscle can not keep pace with the demands of the muscle. When the coronary arteries was reduced by more than 50 to 70 percent, the arteries may not be able to increase the supply of blood to the heart muscle during exercise or other periods of high demand for oxygen. Insufficient supply of oxygen to the heart muscle due to angina. Angina that occurs with exercise or stress is called exertional angina. In some patients, especially patients with diabetes, a gradual decrease in blood flow to the heart can occur without any pain or shortness of breath or fatigue simply unusually early.

Exertional angina usually feels like pressure, heaviness, compression, or pain in the chest. This pain can travel around the neck, jaw, teeth, arms, back, and even, and may be accompanied by shortness of breath, nausea and cold sweat. Exertional angina usually lasts from one to 15 minutes and the rest rejected or taking nitroglycerin, placing a tablet under the tongue. Both resting and nitroglycerin decrease the oxygen demand of the heart muscle, thus relieving angina. Exertional angina may be the first warning sign of advanced coronary artery disease. Pectoral well as a few seconds, rarely due to ischemic heart disease.

Angina can occur even at rest. Angina at rest often indicates that the coronary arteries was reduced to a critical level that the heart does not receive enough oxygen, even at rest. Angina rest can rarely be due to a spasm of the coronary arteries (a condition called Prinzmetal’s or variant angina). Unlike a heart attack, there is no permanent damage to muscle or exertional angina or rest.

atherosclerosis and heart attack

Sometimes the surface of cholesterol plaque in the coronary arteries rupture in May, and formed a blood clot on the surface of plaques. In a clot blocks the flow of blood through the arteries and leads to heart attack (see figure below). The reason for this gap, which leads to the formation of a clot in the main unknown, but factors could include difference in exertional angina or rest, the heart muscle dies during a heart attack and loss of muscle is constant, if the blood flow can be restored quickly, usually within one to six hours.

While heart attacks can occur at any time in heart attack occurs 4:00-10:00 due to higher blood levels of adrenaline released from adrenal glands during the adrenaline chasa.Uvelichenie morning, as already observed, can lead to rupture of plaques of cholesterol.

About 50% of patients who develop the symptoms of heart attack, such as exertional angina or rest angina, heart attacks, but these symptoms may be mild and obvious.

Common Reasons Of Chest Pain

Chest pain generally means heart pain for most people because that is where the vital organs are located. Besides the heart, organs such as lungs, stomach, esophagus and diaphragm are covered by the ribs and muscles in a tight hold that protects them form injury and any external pressure. Chest pains can therefore signal a life threatening situation and the causes can be anything from heart failure to lung problems. Getting help for a heart attack or lung injury could save your life.

The cause of chest pain can be traced to chest wall syndrome in people who don’t have any heart or lung problems. This is the most regular cause chest pain in basic care patients.

Harmless as well as imaginary

Chest wall syndrome is absolutely harmless and musculoskeletal in nature. A person who has chest pain has discomfort originating from the structures of chest wall. Skin, muscles and ribs are included in the chest wall. Pain in chest wall is generally caused by inflammation, injury or infection to these structures. Some common causes of chest wall pain are chest contusion, muscle strain and costochondritis.

Symptoms of chest wall pain include cough, difficulty in breathing, chest swelling, and chest bruising and chest tenderness. The treatments for chest wall pain are muscle relaxants, cold compresses, rest and anti pain nonsteroidal inflammatory medications. Sensitive Heart Syndrome, Atypical Chest Pain and Syndrome X are other chest pains that are caused by blockages in the heart that are not visible.

Besides these kinds of causes, chest pain may also be related to psychiatric conditions and panic disorder. Muscle contractions in the chest wall are likely the cause of chest pain from panic attacks. After panic attack, the chest wall may feel sore for several hours or days. In these cases, patients can be screened by two item questionnaire suggested by American Family Physician online journal. Medication and relaxation techniques can be used for its easy treatment.

Deadly and dangerous

It doesn’t mean that chest pains altogether should be discounted just because many patients complain of chest pains that are often harmless. Heart disease is the leading cause of deaths in the US so far. Aortic dissection, coronary artery spasm, angina, mitral valve prolapsed; Prinzmetals syndrome or Graybiel’s syndrome and Prinzmetalsare are other deadly cardiac causes of chest pain.

Causes of chest pain that are not related to heart are pulmonary embolism, heartburn, pleurisy, pinched nerves, shingles caused by virus, injured ribs, espophageal spasms which are swallowing disorders, lung problems and pancreas or gallbladder problems. Most of these are not quickly dangerous for life but they are as deadly as heart problems when these medical get deteriorated and treatments many not be any more effective. It’s not always easy to tell how one knows when medical help is needed for chest pain. If one is not sure why the chest hurts then it’s best to check it out.
