Heart Attack: the Silent Killer in 21st Century

Introduction:

Heart diseases are extremely common in the present day, given the modern lifestyle and the numerous stresses existing in the 21st century. Ischemia refers to an obstruction in blood flow. Ischemic heart disease (IHD) is a spectrum that includes angina pectoris, atherosclerosis, coronary artery disease, and myocardial infarction. Acute myocardial infarction, commonly known as heart attack, is a serious problem. Approximately one in seven deaths in the United States is because of coronary heart disease, which includes heart attacks.

What Is a Heart Attack?

A heart attack occurs when a part of the heart muscle does not get sufficient blood or the blood flow to the heart is blocked. Angina is a medical term for commonly experienced chest pain. The typical presentation of a heart attack includes left-sided chest pain, chest discomfort, and the feeling of a band being tied around the chest. This pain may radiate to the jaw, left arm, or shoulder. Many perceive this discomfort as vague chest tightness, epigastric discomfort, or burning sensation in the chest. This may also be accompanied by diarrhea. It is frequently misdiagnosed as acidity or gastric trouble. Suffice it to say that consulting a cardiologist is of vital importance in such a situation.

What Are the Symptoms of a Heart Attack?

The symptoms of a heart attack may vary among men and women. The common symptoms include:

What Is the Cause of a Heart Attack?

The cause of a heart attack is a syndrome complex called coronary artery disease (CAD). CAD is caused by plaque, which is the build-up of fatty material in the walls of the blood vessels supplying the heart. These are termed coronary arteries. The components of this fatty material include cholesterol, fibrin, platelets, and other substances. These serve to narrow down the lumen (thickness) of a blood vessel. Such a narrowing down results in obstruction of blood flow to the heart and further leads to a heart attack.

What Are the Tests Done to Diagnose Coronary Artery Disease?

There are several cutting-edge and effective tests available to diagnose CAD. These tests are to be interpreted by a well-trained cardiologist as an interpretation of these tests lays the foundation for further management.

  1. Electrocardiogram (ECG) - This is an electrical recording of the heart which measures the pattern of electrical activity, rate, and regularity of the heart.

  2. Echocardiogram (Echo) - This requires specialized training in its interpretation. This detects areas of poor contractility, areas that are poorly perfused, and structural heart changes. This employs sound waves to create an image of the heart that gets displayed on a screen.

  3. Exercise Stress Test - This is also called the treadmill test (TMT). This determines how efficiently the heart copes during periods of stress when it has to pump at a faster rate to meet the exercising body's increasing demands.

  4. Chest X-Ray - This delineates the enlargement of the heart and gives an idea of the state of the lungs.

  5. Coronary Angiogram - This is the most definitive and important test in determining the blockage of arteries. Angiography is done only by an interventional cardiologist. Here, a thin, slender, flexible guide wire is passed from a major artery in the thigh (femoral) or arm (radial), reaching the heart. A dye is injected, and the blocked or poorly perfused areas where the dye cannot perfuse are displayed on a monitor. This is done under fluoroscopic guidance. The cardiologist then determines the blocked areas by carefully inspecting the screen monitor. This is a safe and painless procedure.

What Are the Treatment Options for Heart Attack?

Several effective treatments are available to treat heart attacks. First and foremost is a lifestyle change, including healthy food habits and regular exercise. Then it has to be followed by drugs and interventional procedures.

1. Drug Therapy

2. Interventional Procedures

3. First Aid

One should also know the following first aid steps for a heart attack, as they must help at times.

Conclusion:

Heart attacks are an important public health problem, and it is critical to increase awareness about them. It is equally critical to consult the right person in such an emergency situation. If a person is at higher risk of heart attack, go for regular follow-ups, testing, and care to avoid any such occurrence.

Frequently Asked Questions


1.

What Is the Duration of a Silent Heart Attack?

The duration of a silent heart attack can vary from person to person. A silent heart attack is chest pain that can last for more than a few minutes. It can stop the blood flow to the heart, hence medical opinion should be obtained at the earliest.

2.

What May Be the Indications of a Silent Attack?

Apart from the physical symptoms, a silent heart attack does not have other indications. Hence, to verify the occurrence of a silent attack the doctor may run a few tests. An echocardiogram or an electrocardiogram can be performed to detect a silent attack.

3.

What Is the Reason for the Occurrence of a Silent Attack?

A silent heart attack may occur when there is an obstruction of blood flow. This obstruction may be caused due to a block in the arteries that may be caused due to plaques. These plaques are calcifications of fat that occur in the blood vessels of the heart.

4.

Can a Silent Heart Attack Cause Death?

A silent heart attack can be the cause of death when left untreated. A silent heart attack can cause considerable damage to the blood supply of the heart. Hence medical opinion should be obtained at the earliest.

5.

What Are the Ways To Prevent a Silent Attack?

The ways to prevent a silent attack may include:
- Regular exercise.
- Eating balanced food. 
- Avoiding alcohol and tobacco.
- Keeping stress at bay.
- Consulting a doctor in case of any symptoms.
- Managing weight.

6.

Can Healthy People Get Heart Attack?

Healthy-looking people may not be always healthy. They may appear seemingly healthy but can have complications of the heart and the arteries. Some basic non-invasive cardiac tests can detect this abnormality and prevent such conditions.

7.

At What Age Do Heart Attacks Occur?

Heart attacks can occur at any given point of time. Heart attacks can affect men at a younger age compared to women. Men over the age of 45 and women over the age of 55 are at a greater risk of a heart attack.

8.

Can Chest Pain Occur Due to Anxiety?

Anxiety can sometimes manifest as chest pain. Chest pain due to anxiety is most often caused due to panic attacks. This may also be associated with shortness of breath. Hence, some symptoms of anxiety can mimic a heart attack.

9.

Can a Stress Test Detect the Blockage of the Arteries?

Yes, the stress test is effective in detecting arterial blockage. It can also detect the reduction of blood flow due to a blockage. However, a stress test can only detect blockages that are more than 70 %.

10.

Is Crying Related To Weakening of the Heart?

Yes, crying and emotional stress can cause weakening of the heart. Sudden emotional stress can cause the weakening of the heart's musculature. This condition may also be known as broken heart syndrome.
