Silent Heart Attack: What to Know About It

A silent heart attack or Myocardial infarction occurs when your heart doesn’t get enough oxygen. It is called a “silent heart attack” as there are mild to no symptoms associated with it.

It has symptoms that people do not associate with a heart attack. According to the studies conducted, approximately 50% to 80% of all heart attacks are silent.

According to the best cardiologists in Delhi, the risk factors associated with a silent heart attack. These include:

  • Age
  • Diabetes
  • Obesity
  • Family history of heart disease
  • High blood pressure
  • High cholesterol
  • Lack of exercise
  • Prior history of heart attack
  • Tobacco use

Having a silent heart attack increases the risk of having a repeat heart attack that can be deadly to you. Although there are no tests available to calculate your chances of a silent heart attack, a cardiologist in Delhi may evaluate your risk factors and treat them to prevent and minimize the chances of having a myocardial infarction.

Reasons Behind a Silent Heart Attack

  1. Higher pain tolerance: People having a higher pain threshold may not feel the pain as acutely and may ignore it as some other minor discomfort.
  2. Medical conditions:Certain medical conditions like diabetes and chronic kidney diseases affect the nerves sending pain signals to your brain. As such, the pain of a heart attack feels reduced.
  3. Cardiac ischemia: Characterized by reduced blood flow to the heart, this symptom may sometimes produce atypical heart attack symptoms. A person may only experience shortness of breath.

Causes of A Silent Heart Attack

The reasons behind a silent heart attack are similar to that of a normal heart attack. They are:

  1. Thickening of the ventricles: 

Sometimes, the ventricles of the heart’s main pumping chamber may stiffen and not fill the blood with each beat. The heart muscle may also weaken, and the ventricle may ultimately stretch to a point where the heart cannot pump enough blood to the body.

  1. Coronary Artery Diseases:

This affects the arteries carrying blood and oxygen to the heart, causing standard lining inside the arteries to break down. This makes the artery walls thick and deposits fat and plaque, blocking blood flow. When the arteries become too narrow or completely blocked, a patient experiences a heart attack. According to the cardiologist in Delhi, immediate heart failure treatment is needed when this occurs.

  1. High Blood Pressure:

High blood pressure refers to the force of blood pushing against the artery walls being higher than usual. When the blood pressure is high, the heart needs to pump harder to move the blood into the body. Over time, this causes stiffening of the left ventricle or narrows the coronary arteries, ultimately leading to a heart attack.

Apart from the above-mentioned causes, the following factors may also increase the chances of a heart attack:

  • Cardiomyopathy
  • Diabetes
  • Congenital Heart Diseases
  • Arrhythmia
  • Kidney Diseases
  • Smoking
  • Obesity
  • Certain medications

Symptoms Of a Silent Heart Attack

Silent heart attack symptoms are less severe than those associated with a regular heart attack. These symptoms are often mistaken for other mild conditions. The best cardiologist in Delhi suggests the following symptoms of a silent heart attack:

  1. Mild discomfort:There may be mild or little pain, but it won’t be as severe as a regular heart attack. There may be discomfort in the upper abdomen, in your jaw, or the back, with pain similar to that of straining a muscle.
  2. Heartburn:There also may be mild pain or irritation and discomfort in the throat or chest that can be confused with gastric reflux, heartburn, or indigestion.
  3. Shortness of breath:If you have breathing trouble after doing any light activity, it may be a symptom of a silent heart attack.
  4. Fatigue:Fatigue or physical tiredness can be a symptom of many other medical conditions. But when associated with a silent heart attack, it is easily confused with other issues like age-related pain or lack of sleep.
  5. Light-headedness:Breaking out in a cold sweat, feeling nausea, or being lightheaded may very well be a symptom of a silent heart attack.

A silent heart attack is often followed by another severe one. To prevent and reduce the risk of a second attack, a cardiologist in Delhi suggests the following measures:

  • A healthy balanced diet
  • Stress management
  • Maintaining a healthy body weight
  • Physical exercise
  • Reducing tobacco use

Following an active and healthy lifestyle and seeking treatment by the best cardiologist in Delhi may reduce your chances of a silent heart attack manifold and prevent it before it happens. Make sure to eat and stay healthy. Also, don’t let stress affect you and try to relax.
