Symptoms of Heart Attack

Symptoms of Heart Attack can help a person save his life due to prompt Heart Attack Treatment.


Myocardial Infarction is the bereavement of heart tissue from the abrupt occlusion of the coronary arteries due to a blood clot. Coronary arteries are the vessels of the blood that provides the heart tissues oxygen via blood. Occlusion to the coronary arteries divests the heart tissues of oxygen and blood causing the damage to the heart muscles. Damage to the heart tissues results to chest pressure sensation and chest pain; if the blood supply is not replenished at some period of 20-40 minutes, irremediable infarction of heart muscles will commence to occur. The death of the muscle will continue for 6-8 hrs. The infracted heart muscles will be reinstated by scar tissue.

What are the Causes of the Symptoms of Heart Attack?

Atherosclerosis is the main root of this disorder. It is a slow process of plaque formation of cholesterol that is set down in the walls of the artery. Plaques of cholesterol can result to the hardening of walls of arteries and the narrowing of the inner lumen (channel) of the artery. Narrowed arteries due to atherosclerosis would not be able to deliver a sufficient amount of blood to sustain the normal purpose of the parts of the human anatomy that they supply.

A good example is the buildup of plaques in the arteries of the legs that can result to the impediment of blood supply to the legs. Reduced blood supply to the legs can consequence to intermittent claudication or leg pain while walking, leg ulcer and an impediment in the healing process of wounds on the legs. Coronary atherosclerosis is described as a disease that caused by the abridged blood flow to the heart tissues from the coronary heart disease that the patient has.

Angina Pectoris is chest pressure or pain that takes place when the oxygen and blood supply to the heart tissues can’t sustain with the necessities of the muscle. The narrowing of the coronary arteries for greater than 50-70 percent may not be able to cope up and increase the blood supply to the heart tissues during work outs or other activities which demands high amount of oxygen. An inadequate contribution of oxygen to the heart will cause angina.

Angina that is precipitated by exercise is termed as stable angina. It typically feels like heaviness, pressure, aching or squeezing across the chest. This pain may radiate to the jaw, neck (See: neck pain relief), back, arms or even on the teeth along with shortness of breath, cold sweats and nausea. It can usually last at a range of 1-15 minutes and is relieved by nitroglycerin and rest. Both interventions can decrease the demand for oxygen by the heart muscles.

What are the Symptoms of Heart Attack?

Symptoms of Heart Attack may vary from one person to another. The common manifestation as mentioned earlier is chest pressure or pain. The quality of pain is a squeezing sensation or fullness on the chest. Another pain associated with this condition is toothache, jaw pain and headache. For the respiratory system’s related symptoms, shortness of breath takes place.

Warning signs may include nausea and vomiting, epigastric discomfort at the upper region of the abdomen, sweating, indigestion or heartburn. Arm pain, typically at the left arm, though it may also occur in the other arm may be evident for some patients. Upper back pain may also be experienced. Majority also exhibit a vague feeling of illness or general malaise. In some instances, a rare kind of angina that doesn’t manifest any symptoms; this is a common condition for diabetes mellitus patients.

Although the manifestations of myocardial infarction at times can be indistinguishable and mild; it is essential to be aware about the symptoms of heart attack. Even though it sometimes produces no symptoms, the severity is still the same, detrimental to the patient’s lives. A person cannot exaggerate the significance of seeking immediate medical treatment in the occurrence of manifestation that proposes a heart attack. Early heart attack treatment and diagnosis is the key to save lives in this condition and a delay on either of this may be damaging to the patient.

What is the Laboratory Diagnosis of Heart Attack?

Numerous laboratory biomarkers for heart attack are available. No single laboratory examination is entirely specific and sensitive for confirming the occurrence of heart attack as commenced by the Symptoms of Heart Attack. CK Total or creatine kinase (total) is an inexpensive and simple test that is available for the public. An increase in the CK total is not a specific indicator of myocardial damage. CK-MB portion is the more sensitive for cardiac muscles for 15-40%. It is elevated within 3-4 hrs of myocardial death, and returns to normal during the 36hrs. Troponin I and T composes the structural constituent of heart muscles. It is released into the bloodstream during the attack. This test is highly sensitive and specific for this condition. Myoglobin is a type of protein seen in cardiac and skeletal muscles.
