Heart Attack: Early Warning Signs, Causes and Treatment Options

Posted on by Prof. Dr. İbrahim Cansaran TANIDIR

A heart attack occurs when the coronary arteries supplying the heart suddenly become blocked, depriving the heart muscle of oxygen and causing serious damage. The most common symptoms of a heart attack include severe pressure or tightness in the chest, pain radiating to the left arm or neck, shortness of breath, and sudden profuse sweating. Genetic predisposition, high cholesterol, and plaque buildup inside the arteries are among the main causes of a heart attack. Current treatment methods include rapid administration of medications to open the blocked vessel, balloon and stent procedures, and surgical intervention when necessary. Early diagnosis and proper medical guidance are the key factors in minimizing heart muscle loss and protecting the individual’s health.

What Are the Symptoms of Heart Attack and Heart Damage in Children?

Children, especially infants, provide clues through their body language because they cannot directly express the discomfort they feel. When the heart becomes fatigued or has difficulty pumping blood, their overall energy levels and physical endurance are directly affected. The main symptoms that may be observed in infants and children include:

  • Excessive sweating during feeding
  • Becoming tired quickly while breastfeeding or eating
  • Rapid and wheezing breathing
  • Pale or bluish skin color
  • Unexplained crying episodes
  • Chest pain during exertion and crying related to the pain
  • Dizziness
  • Fainting episodes
  • A sensation of palpitations
  • Growth retardation

Does Chest Pain in Children Always Mean a Heart Attack?

It is completely understandable for parents to panic when a child says, “My chest hurts.” However, the reassuring fact is that the vast majority of chest pain experienced during childhood and adolescence does not originate from the heart. Simple problems involving the muscles, bones, or cartilage supporting the chest wall are generally the source of these pains. Chest pain unrelated to the heart has several typical characteristics:

  • A stabbing sensation
  • Short duration
  • Worsening with movement or deep breathing
  • Localized tenderness
  • Spontaneous relief while resting
  • A needle-pricking sensation
  • No association with physical exertion

How Different Are the Causes of Heart Attack and Heart Damage in Children Compared with Adults?

While heart attacks in adults occur when plaques accumulated in the arterial walls cause a blockage, this process in children is based on biologically very different mechanisms. Children’s hearts belong to different risk groups because of structural abnormalities and genetic predispositions. The main factors responsible for this difference are summarized below:

  • Coronary artery anomalies
  • Inflammation of the heart muscle
  • Genetic cardiomyopathies
  • Kawasaki disease
  • Familial high cholesterol
  • Congenital heart defects
  • Sequelae of rheumatic fever

How Can Myocarditis Be Confused with a Heart Attack?

Sometimes the heart muscle itself may be affected following a viral infection or a severe cold. This condition, medically known as “myocarditis,” refers to inflammation of the heart muscle. Surprisingly, myocarditis can sometimes mimic the symptoms of a heart attack. The clinical findings and tests evaluated during the diagnostic process include:

  • ECG changes
  • Elevated troponin levels
  • Increased CRP and erythrocyte sedimentation rate
  • Elevated erythrocyte sedimentation rate
  • Increased serum BNP or NT-proBNP levels
  • Enlargement of the heart on a chest X-ray
  • Impaired contraction detected by echocardiography

What Is the Treatment Process for Congenital Anomalies Such as ALCAPA Syndrome?

ALCAPA (Anomalous Left Coronary Artery from the Pulmonary Artery) is a rare condition in which the coronary artery originates from an abnormal location. As pulmonary pressure decreases after birth, the perfusion of the artery supplying the heart changes, and the heart becomes unable to receive sufficient blood. Surgical and medical treatment options for this condition include:

  • Inotropic support therapy
  • Heart failure medications
  • Coronary artery reimplantation
  • Creation of a dual coronary artery system
  • Surgical or angiographic closure from the distal opening site

How Is the Risk of Sudden Cardiac Arrest Managed in Young People?

Sudden cardiac arrest in young athletes or children participating in sports is generally caused by thickening of the heart muscle, known as hypertrophic cardiomyopathy. This condition may prevent the heart from pumping blood with sufficient pressure or may cause an abnormal rhythm during exertion. The main methods used in management strategies include:

  • Regular annual examinations
  • ECG monitoring
  • Echocardiography (ECHO) screening
  • Genetic testing
  • Use of a 24-hour Holter rhythm monitor
  • Exercise testing
  • MRI and/or scintigraphy imaging
  • Beta-blocker therapy
  • Septal myectomy surgery

How Does Kawasaki Disease Affect the Coronary Arteries?

Kawasaki disease is an inflammatory condition affecting medium-sized blood vessels. It most commonly presents with high fever in children between the ages of 2 and 7. Its most critical feature is the weakness it may cause in the vessel walls. Standard methods used in the treatment protocol include:

  • Intravenous Immunoglobulin (IVIG) infusion
  • High-dose aspirin therapy
  • Corticosteroid treatment
  • Biological agents
  • Low-molecular-weight heparin
  • Warfarin therapy
  • Regular angiographic monitoring

Coronary artery involvement may occur in one out of every four untreated children with Kawasaki disease. IVIG treatment can reduce this rate by six to eight times, bringing it down to approximately 1-2%.

Why Should Familial Hypercholesterolemia Be Taken Seriously in Children?

Familial hypercholesterolemia, which is inherited genetically, is a condition in which LDL cholesterol cannot be effectively removed from the body. Extremely high cholesterol levels during childhood may cause arterial hardening, which would normally be expected in adulthood, to begin much earlier. The main approaches followed in children within this group include:

  • Early lipid profile screening
  • Statin therapy
  • Use of ezetimibe
  • Lifestyle modifications
  • Apheresis
  • Dietary counseling
  • Pediatric endocrinology follow-up
  • Regular cardiology follow-up

Which Lifestyle Recommendations Are Important for Protecting Heart Health in Children?

Regulating daily habits to support heart health in children may help minimize long-term risks. Simple but effective habits that parents should pay attention to include:

  • A balanced diet
  • Avoiding processed foods
  • Regular physical activity
  • Limiting screen time
  • Stress management techniques
  • A healthy sleep routine
  • Increasing water consumption

Which Diagnostic Methods Are Used in Heart Health Screening?

Thanks to modern technology, noninvasive methods are now available for examining the heart in detail. Diagnostic tools frequently used in pediatric cardiology centers include:

  • Echocardiography (ECHO)
  • Fetal ECHO
  • Electrocardiography (ECG)
  • 24-hour rhythm Holter monitoring
  • Exercise tests
  • Cardiac MRI imaging
  • Diagnostic cardiac catheterization

What Treatment Options Do Catheterization Methods Offer for Children?

Modern techniques that do not require opening the chest are used to treat certain structural heart defects or vascular narrowing. Common interventional treatments performed through a catheter include:

  • ASD closure procedure
  • VSD closure procedure
  • PDA closure procedure
  • Balloon valvuloplasty/angioplasty
  • Stent procedures
  • Transcatheter valve replacement
