The causes of a heart attack?
Atherosclerosis
Atherosclerosis is a gradual process which plaques (collections) cholesterol deposited on artery walls. Plaques of cholesterol causes hardening of the arterial wall and narrowing the inner channel (lumen) of the arteries. Arteries, thus reducing atherosclerosis can not deliver enough blood to maintain normal operation of body parts of your offer. For example, atherosclerosis of the leg arteries causes a decrease in blood flow to the legs. Decreased movement blood in the legs can cause leg pain during walking or exercise, ulcers in the legs, or delayed healing of wounds in the feet. Atherosclerosis of the arteries are the blood in the brain may lead to vascular dementia (mental due to the gradual loss of brain tissue for many years of degradation) 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 begin to adolescence, but symptoms or health problems usually do not occur later in adulthood when the reduction arteries is severe. Smoking, hypertension, high cholesterol, diabetes and atherosclerosis accelerated in May and complete symptoms and complications before, especially in people who have a family history of early atherosclerosis.
Atherosclerosis (coronary or coronary artery disease) refers to the fact that the cause of atherosclerosis and hardening artery stenosis coronary. Diseases caused by reduced blood supply to the heart muscle called coronary atherosclerosis artery disease Coronary (CHD). CHD includes href = "http://heartattack.ueuo.com/"> heart attack, sudden death, chest pain (angina) abnormal heart rate and heart failure due to weakened heart muscle.
atherosclerosis and angina pectoris
Angina (also called angina pectoris) is chest pain or pressure that occurs when blood and oxygen to the heart muscle can not keep pace with demands of muscles. When the coronary arteries was reduced by more than 50 to 70 percent, the arteries may not be able to increase blood flow to the heart muscle during exercise or other periods of high demand for oxygen. The insufficient supply of oxygen to the heart muscle due to a sore throat. Angina pectoris occurring during exercise or stress is called angina pectoris of effort. In some patients, particularly patients with diabetes, a progressive decrease in blood circulation to the heart may occur without any pain or difficulty breathing or fatigue simply too early.
Effort angina breast usually feels like pressure, heaviness, squeezing 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 sweats. Effort Angina typically lasts from one to 15 minutes and the rest dismissing or taking nitroglycerin, place a tablet under the tongue. Both resting and nitroglycerin decrease the oxygen demand of the heart muscle, relieving and angina. Angina of effort can be the first warning sign of advanced coronary disease. Pectoral and a few seconds, rarely due to a ischemic heart disease.
Angina may occur even at rest. Angina at rest often indicates that the coronary arteries is reduced to a level critical that the heart does not receive enough oxygen, even at rest. Other rare breast may be due to spasm of coronary artery disease ( called variant angina or variant). Unlike a heart attack, there is no permanent damage muscle and effort angina or rest.
atherosclerosis and heart attack
Some times the surface of cholesterol plaque in the rupture of the coronary artery in May, and form a blood clot on the surface of the plates. In a clot blocks the blood flow in arteries and leads to a heart attack (see figure below). The reason for this difference, which leads to the formation of a clot in the main problem, but some factors could include the difference in effort angina or rest, the heart muscle dies during a heart attack and loss muscle is constant, if blood flow can be restored quickly, usually within one to six hours.
While heart attacks can occur at 4:00-10:00 any time to a heart attack occurs because higher levels of adrenaline released by the adrenal glands during the adrenaline chasa.Uvelichenie morning As mentioned above, can lead to rupture of cholesterol plaques.
About 50% of patients who develop symptoms heart attack, as effort angina or rest angina, heart attacks, but these symptoms may be mild and clear.

Interim dose of nitroglycerin?
You have mild chest pain, I think, but I'm not sure if it refers certain diseases of the heart. I take a sublingual dose of nitroglycerin attempts to check whether to submit the pain? I am 60, so far with no medically proven heart disease.
No, because if it is angina pectoris (Depriation of oxygen heart) and is worst, you may be in difficulty. You really need to see doctor today or go to the emergency room and then let decide if they want to try nitro. I had 2 strokes and 2 heart attacks and learned the hard way himself. Take care of yourself with a doctor, not self-medicate,
