Silent Heart Attack

Silent heart is also known as silent killer.

According to medical reports till today heart attack is one of the major cause of death and disability in American citizens. Generally people assume that heart attack begin by series of symptoms such as breathing trouble, pain in the chest, pain in shoulders, indigestion, or vomiting. However, for the victim of silent heart attack this not the case. The silent heart attack comes with unnoticeable symptoms and be just deadly as massive heart attack.

Heart attack occurs when heart does not get sufficient blood and oxygen flow. This process slowly damages the heart muscle leading to a serious heat troubles or sometime life is at stake.

Anyone with science knowledge can easily tell a person complaining of chest pain might be suffering from heart trouble. However, there is yet another deadly form of heart malfunction where casualty and person around him are totally unaware of the danger standing next door. Since there is no major symptoms this heart trouble goes unnoticed. This is the reason it is called mild or silent killer and medically termed as silent heart attack.

The symptoms of the silent heart attack are so inconspicuous that casualty might be treated with immediate cardiac arrest. In silent heart attack victim loses the golden hour of treatment and hence saving his life becomes a much more difficult task. This delay is due to no extreme  symptoms of silent heart attack. Chest pain or pain in left shoulders is the red sign for an oncoming heart attack however; this is not present in silent heart attack. Therefore, saving the causality’s life is bigger challenge for doctor’s in-charge. There is a history as well as huge science behind the silent heart attack. People who are: aged 55 or above, uncontrolled diabetes, follow an unhealthy lifestyle, no workout regime are more in danger to suffer from this deadly attack. Quick treatment  is the key to save silent heart attack casualty’s life. In silent  attack chest pain is reduced after couple of hours rest and this delay’s the right treatment which can be in turn more  devastating.

Here are few silent heart attack symptoms which are generally misconstrued-

  1. Jaw  pain
  2. Pain in left arm
  3. Tiredness
  4. Heart burn or gas trouble
  5. Indigestion

These symptoms are misdiagnosed by the people at home and they themselves lose their life in the hands of silent heart attack. If you determine any of the above mentioned symptoms consult your doctor immediately. Smoking and regular consumption of alcohol can also increase the risk of silent heart attack.

The important point to remember is that everyone can easily reduce or minimize the risk of heart attack by just following some simple steps-

  1. Eat healthy meals
  2. Drink plenty of water
  3. A regular workout regime
  4. Quite smoking
  5. Regular check-up.

Silent heart attack can be fought back by making certain changes in your lifestyle. If you notice chest pain, or have difficulty in breathing don’t wait undergo a heart stress test to ease the future trouble.

Silent Heart Attack

As per the statistics, approximately 25% of all myocardial infarctions are silent in nature and they occur without chest pain or any other symptoms. The silent heart attacks can occur in anyone but it is more likely to occur in persons with prior heart attack, diabetes, older women and those prone to strokes. In fact, those individuals who are taking medication regularly can also experience a silent heart attack.

It is difficult to identify the silent heart attack because it does not have more pronounced symptoms and the best way to identify  is through careful study of medical history of patients, studying ECG and testing blood for cardiac enzymes. The symptoms of a silent heart attack may include discomfort in your chest, jaws or arms which disappears on resting. An individual may also experience shortness of breath and tiredness.

Once it is detected that a person is undergoing a silent heart attack, the best treatment available is to restore the blood supply back to the heart. In order to restore the blood flow to the patient’s hearts, the clots found in the artery should be dissolved (thrombolysis) or arteries can be pushed open by using a balloon (angioplasty). If required, both the thrombolysis and angioplasty can be performed at the same time.

As per the reports, almost 25 percent of individuals who suffered heart attack and are diabetic, did not feel any of the common warning signs like crushing chest pressure, short breathing, arm pain, weakness, or others. The major issue in the providing the treatment to the individual undergoing silent heart attack is the speed at which the patient receives the treatment. As in the case of a silent heart attack, the patient do not feel the symptoms of the Myocardial infarction, therefore the timing of treatment is crucial for saving the life of the affected person and delay may cause the permanent damaged to the heart.

Classification of Heart Attack

There are basically two types of acute myocardial infarction or Heart Attacks including Transmural and Subendocardial.

Transmural MI – It is related to the atherosclerosis that involves major coronary artery. This MI can be further sub classified into anterior, posterior, or inferior Transmural MI depending on the location. Transmural infarcts spread across the entire thickness of the heart muscle and it results from complete blockage of the area’s blood supply.

Subendocardial – This MI involves a small area in the subendocardial wall of the ventricular septum, left ventricle, or papillary muscles. The Subendocardial infarcts results from locally decreased blood supply due to narrowing of the coronary arteries. The subendocardial area is more prone to MI as it is located the farthest from the heart’s blood supply.

In addition to the above mentioned classification, MI can be further sub classified clinically into a ST elevation MI (STEMI) and a non-ST elevation MI (non-STEMI) depending on the ECG changes.

The term “heart attack” is used to refer the sudden cardiac death sometimes that may not be result from acute myocardial infarction. A heart attack is different from cardiac arrest and the heart attack may lead to cardiac arrest. The term cardiac arrest refers to the stopping of the heartbeat, and cardiac arrhythmia. In this case, heart loses its ability to pump the blood to the body parts. In fact, the severe myocardial infarction may cause heart failure however it is not always the case.

The Myocardial Infarction can be classified into five main types:

Type 1 – This refers to the impulsive myocardial infarction that is associated to ischaemia because of primary coronary event like plaque erosion, or dissection

Type 2 – This refers to the Myocardial infarction that is secondary to ischemia. It results from to increased oxygen demand or decreased supply in events like coronary embolism, coronary artery spasm, arrhythmias, and others.

Type 3 – This refers to the sudden unexpected cardiac death comprising of cardiac arrest with symptoms that suggests myocardial ischemia. In this case, the death occurs before the appearance of cardiac biomarkers in the blood

Type 4 – This refers to Myocardial infarction associated with coronary angioplasty or stents.

Type 5 – This refers to the Myocardial infarction linked with CABG (Coronary artery bypass grafting).
